Subject: D.C. Court Rejects FilmOn X Claim to Compulsory License
Meanwhile, on the East Coast: D.C. Court Rejects FilmOn X Claim to Compulsory
License
By Kevin Goldberg, CommLawBlog, December 16, 2015
But District Court decision could be key to a return to the Supreme Court for
Aereo-related issues.
FilmOn X's fortunes have taken a turn for the worse. But for FilmOn X, that
might not be a totally bad thing.
Longtime readers will be familiar with FilmOn X, the Aereo doppelganger. When
Aereo burst on the scene several years ago with its Internet-based,
tiny-antenna approach to the delivery of over-the-air television programming,
FilmOn X followed suit with its own, near-identical system. Parallel copyright
litigation ensued, Aereo duking it out with broadcasters in New York while
FilmOn X faced off against broadcasters in Los Angeles and elsewhere.
Aereo started strong, winning key victories (in both the U.S. District Court
for the Southern District of New York and the Second Circuit), while FilmOn X
didn't. But in 2014 Aereo's streak ended in the Supreme Court, which reversed
the Second Circuit's decision upholding Aereo's approach. The Supremes seemed
swayed by the fact that Aereo looked for all the world like a cable TV
operation -- not a mere equipment provider (as Aereo urged) -- and,
accordingly, the Court concluded that Aereo was retransmitting copyrighted
content, for which it needed a license that it didn't have.

Subject: History--Automatic Electric Co. advertising
Fading from our memory is the once large Automatic Electric Co,
a competitor to Western Electric and major supplier* to the
Independent (non-Bell) telephone companies. AE was also
a popular supplier of PAX--private automatic exchanges.
In the 1950s, AE ran ads in Computers & Automation magazine
for their line of relay and stepping-switch products. Some
are copied and appear below.
Unlike today, the ads focus literally on the "nuts and
bolts" of the product--down to how the bare metal
is formed and assembled. Other ads talk about
the chemical and physical properties of the raw
iron used in a relay core to make the relay fast
acting.
Perhaps if some readers here had experience with
AE exchange or station equipment, they might offer
some observations.
* Back then, AE focused on step-by-step switchgear, which
was the primary mode used by small independent telephone
companies it served. AE was a descendant of the original
Strowger invention. It was later acquired by General
Telephone, a major Independent company (GTE). GTE later
merged with Verizon.
Unfortunately, the illustrations and graphics of
the ads, such as boldface and large type, cannot
be reproduced here. The magazine is available to
view on the bitsavers.org archive site.

New Series PTW Polar Relay replaces WE 255A
... and costs less!
Since Western Electric announced their polar
relays are no longer available, many relay users
have been looking for a suitable replacement.
Look no longer! Automatic Electric's new PTW
Polarized Relay is the complete equivalent
of WE 255A relays in data transmission
circuits. And the PTW series offers outstanding
advantages over the relays you have been using.
Lower cost, for one thing. Less maintenance,
for another. A new concept of relay design assures
adjustments that stay put practically forever.
It's small ... fast ... sensitive. Adaptable
for new or existing installations.
More good news-we can supply PTW series
in practically any quantity-and on short notice. If
you'd like a complete briefing before you order,
write for Circular 1821. Automatic Electric

STANDARDS THAT DETERMINE RELAY QUALITY
trouble-free coil windings
Solderless splice
ends failures two ways
The two chief causes of relay coil
windings going open in service are:
(1) electrolysis, and (2) breaking
at the terminal. Automatic Electric
prevents these difficulties with
a winding termination technique
that is vitally different.
We do not attach coil endings of
fine wire directly to the terminals.
Instead, we carefully strip the insulating
enamel from several inches
of the coil, endings and tightly
twist this length of wire with
strands of bare tinned copper wire.
This strong solderless splice is then
insulated with a special film sheet.
Because we make terminal connections
over a long section of
stranded wire, electrolysis has no
single point to attack. And this
flexible connection will never snap
under temperature extremes or
other stress-producing factors.
In every step of relay design
and manufacture, we take extra
pains to prevent trouble before it
starts.

STANDARDS THAT DETERMINE RELAY QUALITY
contact points that stay on for keeps
Superior attachment
technique guards against
insecure welds.
When you find a relay that sheds
its contacts, you usually have a relay
that's suffering from "cold
welds"; this means that when the
contact spring was made, the contact
and the spring did not really
weld together. When that happens,
the contact is likely to fall off at any
time.
We prevent that, here at Automatic
Electric, by making contacts
from a continuous length of precious metal
wire. In one combined operation,
we weld the end of this wire
to the spring blank (using very accurate
control of time and voltage),
pinch it off so as to provide exactly
the right amount of material for the
contact, and finally form it into a
dome of the contact metal. Result:
a contact with a polished surface,
welded to the spring for the life of
the relay. This is one more reason
why Automatic Electric relays set
performance records of 200 to 400
million operations without a failure!
This superior method is typical of
the painstaking care that goes into
every relay we make.

[ad #4]
Be sure the rotary stepping switches YOU use have this
"free-floating" pawl
Automatic Electric Rotary Stepping Switches
ensure bind-free operation
Look at the pawl in the small illustration above. Automatic
Electric's Type 44 and 45 rotary stepping switches can't
bind. Automatic Electric has eliminated the old-style pawl
stop block that jammed the pawl and caused binding.
Instead, Automatic Electric uses a unique ufree-floating"
pawl, and a set of stopping teeth on the end of the armature.
These teeth engage the ratchet wheel smoothly,
without jarring or jamming. They stop the wiper assembly
positively, and position it exactly right on the
bank contacts.
Automatic Electric offers many exclusive advantages
over older type rotary stepping switches:
* Pawl breakage is eliminated
* He-adjustment of armature stroke is never required
* There's no possibility of pawl binding, even at very
low temperatures
* There's no possibility of double-stepping or overthrow
No wonder more and more design engineers are choosing
Automatic Electric rotary stepping switches!
Plan now to use the Automatic Electric Type 44 or
Type 45 rotary stepping switch in your products.

dependable relays for printed circuits
Maybe you, too, have been awaiting availability of a
good relay for direct insertion into printed circuits. Now
Automatic Electric can solve your problem with a miniature
relay that is just right.
120 million operations, without a single readjustment
or relubrication! That's what you get from. this rugged,
improved Series SQD Relay, because it features a special
heavy-duty bearing and bearing pin. Also a recess in the
bearing plate retains an adequate supply of lubricant
for long-term lubrication of the bearing pin.'
Consider these additional advantages:
1. The sections of the terminals that insert into the
printed circuit board are NOT brazed or welded
into place, but are integral parts of the coil terminals
and contact springs-thus preventing IDternal
loss in conductivity or continuity.
2. Terminal design permits direct plug-in of the relay
into a printed circuit board, ready to be secured-in
place with any acceptable soldering technique.
Usually the desired contact spring combination, or
pile-up, is sufficiently large so that additional mounting
(support) of the relay is not necessary.
SQD Miniature Printed Circuit Relays are available
with many different contact spring arrangements, and
for a multitude of applications. Springs can be made of
phosphor-bronze, ((Bronco" metal, or other specialpurpose
materials, as required.
Of course the long life, heavy-duty features of the
improved SQD Relay can be had in the conventional
type of plug-in relay, if regular sockets are preferred for
use, whether in printed circuitry or other applications.

TO THE ENGINEER
who can't tolerate a lapse of memory
If you're working on a think machine that
can't afford to break its train of thought,
consider AE's pint-size, fast-stepping OCS
switcher. Unlike electron tubes and relays,
this sophisticated device won't lose stored
memory in the event of power failure or
circuit interruption.
Besides, it can do the work normally assigned
to whole banks of relays.
The AE Series OCS will follow or initiate a
prescribed series of events or cycles at 30
steps per second impulse-controlled, or 65
steps per second self-interrupted. Any pro-
gramming sequence can be set up on one to
six cams with as many as 36 on-and-off steps
per cam. And each cam will actuate as many
as six contact springs.
In any event, if your designs involve relays
or stepping switches, AE circuit engineers
may be able to save you a pretty penny. Or,
if you'd like to leave the switching to us,
we're equipped to supply prewired and
assembled, custom-built control units, or help
you develop complete control systems.
To explore the matter, just write the Director,
Control Equipment Sales, Automatic Electric,
Northlake, Illinois. Also ask for Circular
1698-H: Rotary Stepping Switches; Circular
1702-E: Relays for Industry; and our new
32-page booklet on Basic Circuits.

While Bell System publications liked to focus on its
crossbar developments, in reality Bell was a major
step-by-step user as well, and step-by-step grew
in the Bell System, finally peaking in 1974 with
about half of the lines served by it. Common control
systems like crossbar and ESS weren't economical
for small exchanges until the cost of electronics
dropped in the late 1970s.

Subject: Errors in transit cell phone app cause riders to miss
trains
The Philadelphia Inquirer reported today that a digital tool
designed to make riding the regional rail more convenient seems
to be having the opposite effect as SEPTA [Philadelphia transit
carrier] unveils its big schedule changes. Several colleagues
at the Inquirer reported late trains and, possibly worse, missed
stops because of incorrect information on SEPTA's smart phone app.
"There are some issues between what's on our web site and what's
on the app and we are working to correct those," said Richard
Burnfield, SEPTA's deputy general manager. SEPTA officials gave
two examples of the incorrect information that's been turning up
in the app. The included wrongly labeled train times and stops
that were either ommited or listed for trains that no longer
stop at those stations.

elevated trains, and commuter rail in the Philadelphia area.
