Title: A multi-colour liquid crystal display device
Inventor: UCHIDA TATSUO
IPC: G02F1/133
Filed: 1983-09-06
Abstract: A multi-colour liquid crystal display device is described comprising two base plates 11 (11'), each having a plurality of electrodes 12 provided thereon in the form of a plurality of parallel rows, the rows of electrodes on one base plate being not parallel to, and preferably perpendicular to, the rows of electrodes on the other base plate. A plurality of colour filters 13-1, 13-2 13-3, (and 13-4) are provided between the base plates. At least one colour filter is provided in the form of rows parallel to the plurality of electrodes on each of the base plates (11 and 11') so that at least two colour filters overlap. A light path from an electrode on one plate to the corresponding electrode on the other plate passes through one or more of the filters so that a colour display of many different hues is obtained. Subtractive or additive mixing of the colours may occur which may include a combination of primary and secondary colours. A protective film 14 may separate the two sets of filters. <IMAGE>

Title: Seismic exploration system including analog-to-digital converter using delta modulation
Inventor: SHIRLEY THOMAS EDWARD
IPC: H03M3/02
Filed: 1983-11-17
Abstract: An analog-to-digital converter for use in seismic data processing applications is disclosed which features variants on delta modulation and delta-sigma modulation methods. A series of single bits is output by an analog-to-digital converter based on comparison of a predicted analog signal with the actual analog signal. A low pass filter and subsampling operation is applied to the output digital bits to provide digital words corresponding to the analog signal amplitude. Plural integrator stages are shown which allow reduction of quantization error.

Title: Method and arrangement for controlling the combustion process in an internal combustion engine
Inventor: DE FIGUEIREDO NUNO RYBERG MOUS
IPC: F02D41/24
Filed: 1984-07-04
Abstract: In an internal combustion engine (10), the combustion process is controlled by successively adjusting a variable quantity e.g. ignition timing, fuel supply, in dependence upon the instantaneous values of two different parameters e.g. map, rpm, subject to limitations dependent upon the portion of the operating range of the engine. Memory 18 stores values of the quantity corresponding to the values of the parameters. Memory 19 stores limiting values for the variable quantity in different parts of the operating range. Unit 22 forwards the output of memory 18 if it is within the limiting value, otherwise the output of memory 19 is forwarded. An adjustment for fuel type can be provided by unit 21. A knock sensor can be used to modify the contents of memory 19 by means of unit 28. The unit 28 can alternatively respond to undesirable levels of CO in the exhaust or engine temperature to modify the contents of memory 19. <IMAGE>

Title: Gun for driving fasteners
Inventor: LEE KOLYMA
IPC: B25C1/02
Filed: 1984-08-14
Abstract: A gun for driving fasteners such as nails having a guide tube (3) for containing a fastener (N), the guide take being telescopically displaceable into a barrel (H<1>) against a flange (5) carried by a punch member (4) which drives back a hammer (8) against a spring (11) which is thus compressed. A trigger (10) blocks movement of the punch member (4) into a bore (8f) of the hammer member until displaced by a step (H11) in the barrel, upon movement of the tube, flange and hammer rearwardly against the spring 11, to fire the hammer against flange (5) carried by the punch member. In the non-operative mode the trigger 10 engages a stepped portion 4d' of the member 4 to prevent the end part 4e thereof from engaging the bore 8f. When the trigger 10 is displaced the recess 10d thereof becomes aligned with the portion 4d of the member 4 and the bore 8f to cause the mutual engagement of the part 4e and the bore 8f to fire the pin 4 in consequence of the release of the spring 11 tension. <IMAGE>

Title: Method and apparatus for protecting press from being damaged by overload conditions
Inventor: CHI CHARLES HOAI
IPC: G08B21/20
Filed: 1985-07-01
Abstract: A flywheel press is protected from pressure, torsional, energy and power overloading by a computerised safety arrangement. The angular position of a rotating component (eg crankshaft or flywheel) is monitored from which the angular velocity and angular acceleration may be derived. The values of the abovementioned loads can therefore be calculated and compared to determine whether an overload exists. A protective mechanism (eg braking and releasing a buffer) is triggered if any of the above parameters are overloaded. <IMAGE>
