Title: Improvements in and relating to Methods of Manufacturing High-Voltage Rectifiers
IPC: H01L25/07
Filed: 1967-08-23
Abstract: 1,190,048. Semi - conductor rectifiers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Aug., 1967 [26 Aug., 1966], No. 38757/67. Heading H1K. In the manufacture of a high-voltage rectifier comprising a stack of diode elements 10 held under pressure between current supply members in an insulating holder 20, the individual diode elements are subjected after their assembly in the insulating holder to a common etching step. By this means the risk of contamination of the diode elements subsequently to their etching is substantially eliminated. In the embodiment described the diode elements are produced by diffusing phosphorus into one face and boron into the other face of a P-type silicon wafer to create an NPP+ type structure which is then provided with a nickel coating on the two faces by electroless deposition. The nickel layers are sintered by heating to 650 C. and intensified by the electrolytic deposition of gold. One gold layer then has a further rhodium layer deposited on it in order that the electrodes in the diode elements may be distinguished. The diode elements are then obtained by cutting the wafer into circular or rectangular elements. These elements are stacked in a jig upon the spring-loaded cap 18 of the current-supply member 13 until a sufficient number have been assembled; the other current supply member 15 is then pressed upon the stack which is then transferred to the insulating holder 20. In order to clean the diode elements, particularly where the junctions emerge to the surface, the holder with its stack of elements is immersed for 30 seconds in an etching solution containing 100 parts of concentrated nitric acid and 20 parts of concentrated hydrofluoric acid. The assembly is then rinsed in water, etched again in a 2¢% caustic soda solution, rinsed again and dried. As a result of this treatment the gold and rhodium layers project slightly from the sides of the elements. After drying, the space between the stack and the inner surfaces of the holder is filled with a silicone resin and the complete assembly is then encased in a thermoplastic resin, which may be slightly conductive or have a high permittivity to improve the uniformity of the voltage distribution over the stack, Fig. 10 (not shown).

Title: Indicating addressing errors on output devices in data processing  systems
IPC: G06F3/147
Filed: 1973-08-17
Abstract: 1441418 Testing store addressing circuits INTERNATIONAL BUSINESS MACHINES CORP 17 Aug 1973 [23 Sept 1972] 39050/73 Heading G4A In a system in which data is read from an addressable store and reproduced on an output medium, e.g. a CRT or printer, at a location corresponding to the address from which it was read, the store addressing circuits are tested by reading into each store address which is accessible by the energisation of a single address line, and, if necessary, into one or more succeeding addresses, one or more test characters indicative of the line so that on a sequential read out of the contents of the store the absence of the correct test data on the output medium is indicative of an addressing error. As described data is read from a store 20 for display on a CRT 25, the beam deflection signals from the CRT providing address signals for the store which is initially loaded using unit 21. The data read from the store modulates the beam intensity in the tube so as to reproduce the data. As described the store contains 16 rows each of 56 character positions, i.e. 896 character positions 0-895, and 10 address lines. Each address line, when energised alone, addresses a particular character position, e.g. line I position 1, line 2 position 2, line 5 position 16, . . . line 10 position 512. In order to test the store a test pattern is loaded, the pattern, Fig. 1, consisting of decimal numbers equivalent to the binary significance of each address line, e.g. 16 for line 5, each number being loaded in the character position which is accessed by the corresponding address line, except that where the number has more than one digit its digits are recorded in successive positions beginning with the highest ordered digit in the position which is accessed by the relevant address line. By reading out the test pattern on to the CRT addressing errors may be identified. For example if address line 1 is permanently fixed at logic 1, when an attempt is made to address the first character position, i.e. position 0, position I will be addressed and the first character displayed will be 1 rather than zero indicating the fault. Other positions will also be disturbed, e.g. when addressing position 16 position 17 will be addressed and a 6 will appear in position 16 instead of 1. If however line 4 is permanently fixed at 0 when an attempt is made to address position 4 position 0 will be addressed instead so a 0 instead of 4 will be displayed at position 4 thus indicating the fault.

Abstract: 1,164,239. Change-speed control. FORD MOTOR CO. Ltd. 31 Aug., 1967 [12 Oct., 1966], No. 39890/67. Heading F2D. A tractor transmission comprises forward and reverse range clutches 86, 88 with a manual selector valve 246, the operation of which may be automatically inhibited by an interlock mechanism actuated by an hydraulic blocker valve 286 if the engine speed exceeds a predetermined value. Transmission details.-An hydraulic torque converter (20), Fig. 1A (not shown), is followed by the range clutches 86, 88, the output members of which carry forward and reverse pinions 60, 64 driving the input shaft 130 of a four-speed constant-mesh gear gear-box with pairs of nipions 140, 142 and 144, 156 meshing output pinions 104, 106 and 122, 126, the ratios being engaged by a pair of double dog clutches 110, 154. Hydraulic system.-An engine-driven pump 32 supplies pressure liquid through a regulator valve 182 to a torque converter supply line 218 and to a second supply line 184 connected to the selector valve 246 which controls the clutch pressure liquid through lines 264, 266. The valve 246 is held in its reverse, neutral and forward settings by spring detents 276 engageable with recesses 278, 280, 282 in the valve casing. The blocker valve 286, Fig. 5, comprises a pair of vertical plungers 290, 292 normally urged upwards by springs 296, 298, the lower ends of the plungers engaging blocker pins 306, 308 whose lower ends are located adjacent the lands 256, 258 of selector valve spool 248. The pump pressure line 184 is extended to communicate with the upper surfaces of plungers 290, 292, the lower surfaces of which communicate with the clutch supply ports 260, 262 through cross connections 314, 316. Operation.-Forward or reverse drive is effected by valve 246 connecting clutch supply line 266 or 264 with pressure line 184 through port 262 or 260, while the desired ratio is engaged by the appropriate dog clutch 110 or 154. In the event of the engine speed becoming excessive with valve spool 248 in its neutral setting the pressure in line 184 acting on plungers 290, 292 overcomes springs 296, 298 and both blocker pins 306, 308 are projected to prevent movement of the valve. If the selector valve is set for forward drive the connection 316 is open to exhaust so that the pressure acting on plunger 290 causes pin 306 to be projected and thus prevent valve spool 248 from being moved to the reverse setting. At the same time passage 314 is pressurized, so that pin 308 is held raised to allow movement of valve spool 248 from forward to neutral setting. If the selector valve is set for reverse drive the operation of pins 306, 308 is reversed, to prevent engagement of forward drive but allow the selector valve to be returned to the neutral setting.

Filed: 1972-08-30
Abstract: 1395193 Automatic exchange systems SIEMENS AG 30 Aug 1972 [30 Aug 1971] 40102/72 Heading H4K In an exchange system in which some of the subscribers have two different transmitter/ receiver units, e.g. a telephone set and a data unit, and in which the priority afforded to the connection is dependent on the particular transmitter/receiver unit in use, a priority store associated with the exchange junctor supervising the connection is arranged to be updated when a subscriber switches from one transmitter/receiver unit to the other during an existing connection. This enables for example a break-in inhibition to be introduced when a data unit is switched in without a break in the connection following a normal telephone conversation between two subscribers. The arrangement is particularly applicable to PBX's. It may also allow different metering rates for normal and data calls to be charged. As shown diagrammatically two subscribers are interconnected via subscriber line circuits TS1, TS2, switching stages KF1, KF2 and a junctor Ue, having associated therewith a signal analyser AW, a pulsing device TK and a memory BK in which the priority of the connection associated with the junctor is stored. The change in priority is initiated by the operation of the subscriber switches W1 or W2, either manually or automatically, this operation being signalled to the junctor using A.C. or D.C., e.g. impedance, signalling. Separate signalling wires may be used for this purpose. The junctor may in fact intercept a signal from subscriber station 1 to subscriber station 2 which signal is indicative of the switching in or out of the data unit. Where D.C. signalling is used the junctor may be provided with a line transformer to enable D.C. signals to be intercepted. Alternatively the junctor may intercept a preliminary data signal, this being achieved using a transformer winding and filters or the junctor may detect the change in line impedance that will occur when a switch from a speech to a data unit or vice versa takes place. In addition to changing the break-in criteria, the switching of the priority may also be used to initiate a change in charge rate, e.g. when a data unit is switched in, a change in the metering pulse train may take place in such a fashion that a trunk connection is simulated i.e. the call is charged at a higher rate.
