Patent GB-1333137-A (GB)
Title: Elevator control systems
IPC: B66B1/18
Filed: 1971-04-19
Abstract: 1333137 Multi-car lift control HITACHI Ltd 19 April 1971 [8 April 1970] 26516/71 Heading B8L To avoid bunching in a multi-car lift system, a succeeding car is arranged to selectively neglect hall calls as it approaches and passes a preceding car. Determination of distance between cars, Fig. 2.-When car A is several floors behind, say, car B, and moving upwards, a car position signal, say F2UA, which represents the actual position of a stationary car, or a position one or two floors ahead of the actual position for a car moving at medium or high speed, is passed via OR gate 0F2U1A and inhibit element 1F2UA through resistor r a  to ground. The output of 1F2UA provides also a signal for 1F3UA whose output also passes via resistor r a  and provides a signal for 1F4UA &c. Assuming lift B is at the eighth floor and moving upwards, a signal F8UB is present, and via OR gate 0F8U2A inhibits element 1F8U interrupting the chain of currents through r a  and r2UA-r7UA, respectively, whose resistances are equal, r say, since r a  << r, the level of signal SSA is proportional to the number of floors between ears A and B. For distance determination the landing positions are effectively in a ring 1U-9U- 10D-2D-1U, although an upward moving lift responds to "up" calls only from higher landings or a down call from the uppermost landing, and vice-versa. Limitation of the response of following car A to hall calls, Fig. 5a.-The distance signal SSA is combined in a summing device ADD2A, where corrections are made for passenger weight; and total number of cage calls via signals WDA, NCA, proportional to the respective quantities, respectively, and compared with preset voltages V3, V1, V2 corresponding to a basic separation of two, one, or zero floors respectively. As car A approaches from behind, and as the modified signal from ADD2A decreases through V3, V1, V2, respectively, (a) memory MCMA is set, (b) an inhibiting signal E1A is emitted after a given delay provided by T1A, T2A stopping response of car A to hall calls one floor ahead, (c) inhibiting signal E2A, emitted after a delay provided by T3A, stops response of the car to hall calls one or two floors ahead, provided that the total number of hall calls, represented by proportional signal NHC, is less than a given number, and a pulse signal EA is produced, and used to prevent 'the production of signals corresponding to E1A, E2A, EA for the car being passed. The network, using logic elements, which serves to limit the response of car A to hall calls in dependence on signals E1A, E2A is displayed in Figure 6 (not shown).

Title: Improvements in apparatus for recording television images on film
IPC: H04N5/84
Filed: 1951-11-15
Abstract: 710,721. Television. PARAMOUNT PICTURES CORPORATION. Nov. 15, 1951 [April 2, 1951], No. 26785/51. Class 40 (3) Television pictures reproduced at 30 frames per second on cathode-ray tube 12 are recorded on an intermittent motion film camera operating at 24 frames per second under the control of a blanking arrangement 15 which releases the tube beam to reproduce pictures for periods corresponding to the 525 lines forming a complete television frame at a 24 cycle per second rate in synchronism with the camera motion. The driving shaft of the camera intermittent mechanism carries a small magnet 25 by which a pulse is induced in a stationary coil 26 at the end of the film pull-down movement. The pulse passes through a shaping circuit 30 and operates a trigger circuit 22 to open a gate 21 through which the television synchronizing pulses pass to a counter circuit 28 and a blocking tube oscillator 27. The first synchronizing pulse triggers the oscillator which in turn operates a second trigger circuit 29 to release the cathode-ray tube beam. The counter circuit responds to 525 synchronizing pulses and at the completion of the count resets the two trigger circuits the first to close gate 21 and the second to suppress the cathode-ray tube beam. The circuit is thus reset and rests until the next pulse from the camera initiates a further cycle of operation. The magnet and coil 23, 26 may be replaced by a contact system. Specification 672,877 is referred to.

Title: Improvements in or relating to vehicle brakes
IPC: F16D66/00
Filed: 1937-10-04
Abstract: 503,485. Testing brakes ; electric signalling systems. GALLE, J. B. P. H. Oct. 4, 1937, No. 26846. Convention date, Oct. 8, 1936. [Class 103 (i)] [Also in Group XXXVIII] Means for comparing the braking action of the brakes of a vehicle comprises a thermometric resistance or a thermo-electric cell associated with each brake and so connected in a circuit in pairs or otherwise with a galvanometer that when the temperatures of the brakes and thus the braking actions thereof are the same the galvanometer is not deflected. Thermo-electric couples 1, 2, 3, 4, Fig. 1, associated each with one of the four brakes of a vehicle may be connected in opposition in pairs as shown, the pairs 1, 2 and 3, 4 being connected in turn to the galvanometer B by a switch. The switching arrangements may also be such as to allow of connecting the pairs 1, 3 and 2, 4 to the galvanometer. When thermometric resistances 1, 2, 3, 4, Fig. 3, are used instead of thermo-electric cells, these may be arranged as a Wheatstone's Bridge as shown. As long as the temperature of the brakes and thus the resistances remain equal the galvanometer is not deflected. To determine which brake is out of adjustment when the galvanometer is deflected, the resistances may be disconnected in pairs and invariable resistances R1, R2 be substituted in the corresponding branches by switches Dl, D2. In the case of the six brakes of a six-wheeled vehicle, branches 3, 4, for instance, may each include the resistances of two brakes. The thermometric elements may be arranged on a brake shoe or within the drum and with the remainder of the testing apparatus may be removable for use in garages &c. According to the Specification as open to inspection, under Sect. 91, thermometric resistances may be arranged to be connected separately in turn to a galvanometer or a pair may be connected to the two windings of a differential galvanometer. Further, four thermo-electric cells may be connected in series or in opposition in the branches of a bridge in the diagonal of which a galvanometer is connected. Thermometers operating by expansion of solids and liquids and connected to indicators by hydraulic or mechanical means may also be used. The arrangement of a pair of steam-pressure thermometers acting differentially on a pointer through distortable metal manometric tubes is also described. This subject-matter does not appear in the Specification as accepted.

IPC: H01L29/80
Filed: 1967-06-13
Abstract: 1,170,488. Semi-conductor devices. SOC. EUROPEENNE DES SEMICONDUCTEURS. 13 June, 1967 [14 June. 1966]. No. 27192/67. Heading H1K. The channel of a field effect transistor is defined between a buried primary gate region extending parallel to one major surface of the wafer, to which it is connected by a central extension, and at least one annular secondary gate region extending from the major surface into the wafer towards the primary gate region. One of the source and drains region is located in the gap between the central extension of the primary gate region and the secondary gate regions and the other of the source and drain regions is located in the major surface surrounding the secondary gate regions, or, if the edge of the primary gate region stops short of the edge of the wafer, in the opposite major face of the wafer. The device illustrated in Fig. 6 (only one quarter being shown) is produced by diffusing boron into an N-type silicon wafer 1 using an oxide mask to form a P-type region 4, Fig. 1 (not shown). An N-type epitaxial layer 5 is deposited on the surface to bury region 4. During the deposition impurities from region 4 diffuse into the lower part of the epitaxial layer, Fig. 2 (not shown). Region 4 forms the buried primary gate region and its centre is extended to the surface by diffusing boron into the epitaxial layer to form region 8, Fig. 3 (not shown). An annular P-type secondary gate region 11 is diffused into the epitaxial layer, the gap between regions 11 and 4 constituting the channel of the device, Fig. 4 (not shown). Phosphorus, arsenic or antimony is then diffused into the lower face of the wafer to form an N + type drain region 12 and into the epitaxial layer 5 to form an annular N + type source region 13  between regions 8 and 11, Fig. 5 (not shown). The surface is then covered with an oxide passivation layer (18), the source region 13 and gate regions 8 and 11 are contacted by aluminium layers evaporated into windows in this layer, and the drain region 12 is contacted by an antimony-containing gold foil 14 by means of which the device is mounted on a header. In a modification. Fig. 7 (not shown), the gate regions (4 and 11) are connected together by providing region (11) with an inwardly extending arm which contacts region (8). The source region (13) is provided with a gap through which this arm passes. In a second modification, Fig. 8 (not shown) the gate regions 4 and 11 are connected together by diffusing one or more regions (20) into the epitaxial layer simultaneously with region 8 at points lying on the path into which region 11 is subsequently diffused. The device may be provided with two concentric annular secondary gate regions. A plurality of devices may be produced simultaneously in a single wafer. Also the device can form part of an integrated circuit in whch case the drain is formed as an annular region at the same face as, and surrounding, the annular gate regions.

Abstract: 1,107,611. Thermoelectric apparatus. T. M. ELFVING. 29 June, 1965 [1 July, 1964], No. 27580/65. Heading H1K. [Also in Division F4] A thermoelectric heat pump assembly comprises hot and cold junction bridges connected between semi-conductor bodies of opposite conductivity types the cold bridges being in the form of metal containers for receiving a liquid to be cooled. Fig. 2 shows a plurality of cups 12 for containing water to be frozen into ice cubes, the cups 12 constituting electrical bridge connections at the cold positions of thermoelectric elements 13. Tubes 14 containing water provide electrical connections and constitute heat sinks at the hot junctions of the elements 13. The tubes 14 may comprise metallic portions connected by " Teflon " (Registered Trade Mark) rings 15 or may be formed by metallization of portions of a thin ceramic tube. The assembly is mounted in a tray 21 which may be rotated by shaft 22. Fig. 1 (not shown) shows the tray (21) in a heat insulated cabinet with means (19) for filling cups 12 with water and a storage chamber (29) for ice cubes. Tray (21) may be rotated by handle (23) and switch contacts (37-42) are arranged to reverse the polarity of the supply current for the thermoelectric elements when tray (21) is inverted so that cups (12) are heated to release the ice cubes by gravity. A weight (43) restores tray (21) to an intermediate, electrically disconnected, position when the ice is released. In manufacture, the elements 13 may be soldered to tubes 14 by passing hot liquid (glycerin) through pipes 14 to melt bismuth-tin solder. A modification is decribed (Figs. 3 and 4, not shown) in which the hot junctions are air cooled with conduction through copper rods which contact a double walled heat transfer panel filled with a refrigerant such as " Freon " (Registered Trade Mark); in another example, Figs. 5 and 6 (not shown) cooling of the hot junctions is effected by using bridge members of hollow copper sections comprisng arm members to reduce the electrical resistance and increase heat exchange
