Patent EP-0168149-A3 (EP)
IPC: G01L1/22
Filed: 1985-05-28
Abstract: Strain gauges (R1, R2, R3, R4) are arranged in a bridge 
formation to eliminate errors. To reduce these further, 
particularly those arising from temperature variation, each 
branch of the bridge may be composed of a series of small 
gauges  
(R, R, R, R)   
 
and these are all spatially intermixed over the area of the 
transducer. Alternatively, the gauges (6, 8) are stacked on 
each other, with insultating film (7) between, to reduce the 
overall area, or pairs (9, 10) may be interdigitated and the 
pairs stacked with insulating film (11) between.

Abstract: Apparatus for producing high definition projected 
video images comprising light-emitting means providing in 
use at least one collimated beam of light, acousto-optic 
means for modulating said at least one beam of light, 
means for scanning said at least one beam of light at a 
substantially constant angular velocity in a plane 
aligned with the direction of travel of the modulating 
sound in the acousto-optic means and means for matching 
optically the angular velocity with respect to the 
scanning means of the modulating sound in the acousto-­
optic means to the angular velocity of beam scanning of 
the scanning means so that said modulating sound angular 
velocity or the angular velocity of an image of the 
pattern thereof is substantially equal to and aligned 
with said beam scanning angular velocity and, for a 
given length of optical path intermediate the position 
of modulation and the scanning means, the bandwidth of 
the projected video image is substantially greater in 
use than the bandwidth achievable with a single channel 
acousto-optic modulator positioned at the Scophony

being no less than said given length of optical path.
Patent EP-0219200-A3 (EP)
IPC: B41C1/18
Filed: 1986-08-06
Abstract: By using the power and controllability of 
computer-controlled gravure cylinder-making, and by 
careful coordination of this with the manufacture of 
lithographic proof prints via scanning and platemaking, it 
is possible to ensure that a litho proof looks exactly the 
same as the final gravure printed product. Working in 
this way avoids the substantial inconvenience and cost of 
final proofing "on machine", and the risks of having to 
remake one or more gravure cylinders. This approach to 
proofing for gravure work is controlled, in accordance 
with the invention, by the use of a test strip or area 
which is subjected to processing in parallel to the image. 
Use of a test strip enables gravure cylinder engraving to 
be specified, checked and accurately monitored by a 
printer without needing to place the cylinder in a 
printing press. Furthermore, when the cylinders are on 
press, final adjustments before a run can be made easier 
and more rapidly using the test strip or area and a narrow 
format stock.
Patent EP-0232594-A3 (EP)
IPC: F41B6/00
Filed: 1986-11-14
Abstract: A projectile (16) is accelerated in a barrel bore by apply­
ing a plasma jet to a projectile propelling fluid (102). The 
plasma jet is derived from a structure forming a capillary pas­
sage (22) having a wall formed by a low molecular weight, di­
electric powdery filler or water in many rigid containers, 
shaped as spheres (69) or strawlike tubes having axes parallel 
to the passage longitudinal axis. The fluid and jet interact so 
the fluid is heated by the jet, whereby low atomic weight con­
stituents of the fluid are sufficiently heated to become mixed 
with the plasma to form a high pressure mixture that is injected 
into the bore to accelerate the projectile. The fluid (102) is 
dragged into the plasma during mixing to cool the plasma and 
form a boundary layer between the plasma and the barrel walls 
so that the mixture does not cause substantial damage to the 
walls of the bore. The plasma is energized by applying voltage 
from an electric pulse source to electrodes (23, 24) at opposite 
ends of the passage (22). The pulse has a wave shape and du­
ration for initially igniting the plasma source and for thereafter 
applying energy to the ignited plasma to control the pressure 
of the mixture. Initially, the fluid cools the plasma without the 
mixture developing sufficient pressure to accelerate the pro­
jectile appreciably. The wave shape and duration are such that 
the pressure applied to the projectile remains substantially 
constant while the projectile is being accelerated through the 
barrel, as occurs during about one-half of the projectile travel 
time in the barrel.

Title: Combination tasi and adpcm apparatus
IPC: H04J3/17
Filed: 1986-04-10
Abstract: A digital circuit multiplication system for interconnecting a transmission trunk link having a plurality of bearer channels to a second plurality of telephone communication trunks, with the second plurality exceeding the first. The system comprises transmission apparatus at a first end of the transmission link within which there is apparatus for detecting signals on the second plurality of telephone communication trunks and apparatus for assigning each trunk on which signals are present to an available one of the first plurality of bearer channels and for providing assignment messages indicating such assignments. The speech signals are transmitted in bit reduced form by adaptive differential pulse code modulation (ADPCM) transmitting apparatus which is operative to be coupled to the first plurality of bearer channels. The output of the ADPCM transmitting apparatus is combined with the assignment messages along the first plurality of bearer channels, and the assignment messages are stripped from the speech signals at the other end of the transmission link by a signal receiving and message detection apparatus. A receiving apparatus operates to assign each of the first plurality of bearer channels carrying signals to a corresponding one of the second plurality of trunks in accordance with the assignment information received from the transmission apparatus. The signal receiving and detection apparatus contains delay circuitry for temporarily storing the received signals and detecting whether there are assignment messages contained in them, whereupon if these are detected, a message extractor apparatus replaces them with output signals constituting a predetermined signal pattern.

Title: Mixer drive apparatus
IPC: B01F15/00
Filed: 1987-03-27
Abstract: Mixer drive apparatus, which provides gear reduction for driving the impeller shaft of the mixer. A drive shaft (22) from an electric motor (18) is parallel to the impeller shaft (34) which extends through a support collar of a housing where the collar has a hole therethrough into which the impeller shaft extends into the housing. A hub (38) is rotatably mounted on the outside of the housing (10) and carries a gear (42) which is coupled to a pinion on the motor drive shaft. A coupling (70) is attached to the hub and bridges the hole in the collar. The end of the impeller shaft is cantilevered and overhung from the coupling. A gap is defined between the impeller shaft and the inside surface of the support collar which is adapted to receive a seal assembly. The seal assembly (30) includes a retainer hub which captures a sleeve containing the seal structure in the gap between the coupling and the retainer. The seal sleeve (40) may readily be removed upon disassembly of the coupling, which has two sections defining a split ring which clamps the upper end of the impeller shaft, and has a thrust plate with a bolt therethrough into the end of the impeller shaft for axially adjusting the location of the shaft so as to bring the seal sleeve into engagement with the coupling for rotation therewith. A support collar on the impeller shift engages the retaining hub when the coupling releases the shaft for the removal and replacement of the seal sleeve assembly. A seal captured by the collar engages the retainer hub and provides a pressure seal to facilitate replacement of the seal sleeve when the mixer is used with a pressurized vessel.

Abstract: A process for manufacturing a DMOS transistor in 
accordance with the present invention including the steps of 
forming a layer of gate insulation (12, 14) on an N type 
substrate (10). A layer of polycrystalline silicon (16) is 
formed on the gate insulation layer. A first mask is 
used to define the polycrystalline silicon gate. A layer of 
silicon dioxide (20) is then formed on the polycrystalline 
silicon gate. A second photolithographic mask is 
formed on the wafer. The second photolithographic mask 
defines the region where electrical contact is to be made to 
the polycrystalline silicon gate as well as where a deep 
body region (24) is to be formed in the semiconductor 
substrate. The deep body region is then formed. There­
after, portions of the gate insulation layer not covered by 
the polycrystalline silicon gate are removed. The P type 
body region (26) and N+ source region (28) are then formed 
having a lateral extent defined by the edge of the 
polycrystalline silicon gate. A conductive layer 30 is 
formed on the wafer and photolithographically patterned, 
thereby leaving a gate contact and a source and body 
contact. A passivation layer 34 is then formed on the 
wafer, portions of which are photolithographically removed, 
thereby defining bonding pads. Of importance, the above-­
described process uses only four photolithographic masking 
steps.

composition with respect to the OH groups and contacting 
the thus-formed magnesium-containing carrier with a solu­
tion of at least one transition metal compound. Prior to con­
tacting the magnesium-containing carrier with the transition 
metal compound, most of the liquid must be removed there­
from, so that it comprises not more than about 6% of the 
liquid. The amount of the transition metal compound is such 
that the molar ratio of the transition metal to magnesium in 
the reaction mixture is about 0.3 to about 0.9. Also disclosed 
is a process for polymerizing alpha-olefins in the presence of 
the catalyst of the invention.

Title: Circuit for reducing electromagnetic interference from magnetic core keyboards
IPC: H03K17/16
Filed: 1987-02-24
Abstract: The present disclosure describes circuit variants for reducing electromagnetic interference from saturable core keyboards to acceptable levels. The invention finds particular application in conjunction with capacitive-discharge scan techniques used in such keyboards. In order to attenuate the external field resulting from such techniques, a circuit is taught which effectively disconnects the scan line array from the capacitor charging circuit during the time between scans. A second variant, when added to the first, further reduces interference by disconnecting the entire scan circuit from the supply potential during the scan time thereby eliminating steady-state currents and turnoff oscillatory transients.

IPC: H03F3/45
Filed: 1987-12-14
Abstract: An improved line receiver with high common mode 
rejection is operable at voltages above the power supply 
voltage (VCC) as well as below ground. Input resistors 
provide high input impedence as well as means through which 
current summing of current mirror currents at the input 
transistor base nodes is translated into voltage drops which 
boosts the common mode rejection range of the circuit. 
Built-in hysteresis circuitry ensures proper detection of 
non-common mode signals. The high input impedence and high 
sensitivity allow multiple receivers of the type to be 
connected in parallel across a common bus for interrogation 
by a remote system. The preferred embodiment of the present 
invention is implemented in integrated circuit technology.
