Patent EP-0246784-A3 (EP)
IPC: H01L21/67
Filed: 1987-05-07
Abstract: Apparatus for thermal transfer with a 
semiconductor wafer in a vacuum processing chamber 
includes a platen with a surface for supporting the 
wafer, a clamping ring for clamping the wafer to the 
platen, and passages for supplying a low pressure 
gas into a thermal transfer region between the wafer 
and the platen surface. A low compliance seal 
surrounds the thermal transfer region and inhibits 
the gas from reaching the processing chamber without 
overstressing the wafer. The seal includes an 
elastomer ring having an elongated cross-section, 
and a sealing groove having a first groove portion 
for gripping one edge of the ring and a second 
groove portion which receives the other edge of the 
ring by bending deformation thereof when a wafer is 
clamped to the platen. In a preferred embodiment, 
the ring has a parallelogram-shaped cross-section 
and is oriented at an acute angle to the platen 
surface.

Title: Miniature circuit breaker with improved longevity
IPC: H01H71/16
Filed: 1988-03-25
Abstract: A circuit breaker device has a chamber in which is disposed a 
single break contact system using low contact resistance material 
mounted on movable and stationary supports arranged in a loop 
configuration in order to direct arcs between the contacts 
through an arc chute into a remote portion of the chamber. A 
push-button is connected through a kinematic linkage which 
transfers motion using minimal frictional engagement to a movable 
contact to bring the movable contact into and out of engagement 
with a stationary contact and to latch the contacts in engagement 
during normal operation. A cantilevered current carrying bimetal 
transfers motion caused by I R heating of the bimetal to an 
ambient compensating bimetal connected to the latch mechanism. 
The kinematic linkage includes a latch surface which engages a 
rollable cylindrical reaction surface of the latch mechanism to 
cause the movable contact to come into engagement with the 
stationary contact upon depression of the push-button. Upon 
overload, the latch mechanism is displaced with the latch surface 
moving away from the reaction surface allowing return springs to 
return the push-button to its unactuated position and separate the 
contacts.

Patent EP-0311355-A3 (EP)
Title: Electric motor controllers
IPC: H02P7/298
Filed: 1988-10-04
Abstract: An electric motor controller comprises a circuit for 
selecting between driving and braking an electric motor 
in accordance with the health or otherwise of a pair of 
main electric motor control switches (14 and 16). In a 
preferred embodiment the health of the switch is 
determined by the voltage (A) between the switches. 
The controller also comprises means for detecting the 
sense of movement of the motor. In the event that the 
motor is moving in a sense opposite to that selected, 
the means increase field current to reduce the armature 
current thereby increasing the braking effect of the 
motor. Also in the controller are means for changing 
from armature to field current control and vice versa, 
in response to a given magnitude of control signal. In 
order to provide an unambiguous change-over, a lockout 
circuit is provided to inhibit change-over in a 
transition region. The lockout circuit maintains the 
mode of control to above/beneath the change-over level 
when changing from one level to another. The 
controller has a drive circuit which uses a flywheel 
inductor to provide an enhanced actuating signal for a 
transistor control switch for the motor. In a first 
state, the inductor is connected to by-pass the 
transistor to build-up a flywheel current. In a second 
state, the flywheel current is arranged to be applied 
to the transistor as a spike input.

Patent EP-0350554-A3 (EP)
IPC: G08B25/10
Filed: 1988-11-14
Abstract: A vehicle security system (10) can be fitted to a vehicle 
which has a radio transmitting device (14) such as a 
cellular telephone, PMR or CB set. A control unit (12) is 
arranged to periodically alert the driver of the vehicle to 
record a location message. When an alarm condition is 
signalled to the control unit from an alarm system (22), a 
panic button (20) or a radio receiver co-operable with a 
remote panic button transmitter (26), the control unit (12) 
initiates a transmission from the radio transmitting device 
(14). The message transmitted includes the last recorded 
location message and may also include vehicle identification 
information and a mileage update message generated in 
response to the output of a vehicle odometer (34) to 
indicate the distance travelled by the vehicle since the 
last location message was recorded by the driver. The same 
security system may also be constructed as a portable unit.

Title: Closed circuit television system having seamless interactive television programming and expandable user participation
IPC: H04N7/173
Filed: 1988-10-26
Abstract: A closed circuit interactive television 
system (10) provides a multichannel television signal 
from a localized head end (12) which is used for indi­
vidualized interactive selections by a plurality of 
users (22, 24, 26). Each user station contains a con­
ventional television receiver (32a, 32b, 32c) and 
a smart box or interface and selection device (30a, 
30b, 30c). The smart box or interface and selection 
device (30) is disposed between the television receiver 
(32) and the RF distribution amplifier (36). The 
number of user stations (22, 24, 26) on the system (10) 
is virtually unlimited. The system (10) provides the 
audio/video television signals (14, 16, 18, 20) in at 
least frame accurate synchronization to enable seam­
less video switching between channels, which seamless­
ness is enhanced through the view of a pair of tuners 
in the interface selection box (30a, 30b, 30c) which 
are alternately commanded to pretune to the channel of 
the next actual choice made prior to the changeover 
under control of a microprocessor in response to command 
signals embedded in the television signals being 
received.
