Title: Alarm system
Inventor: JONES LEONARD HAMILTON HOWARD
IPC: G08B13/20
Filed: 1969-11-04
Abstract: 1,254,130. Burglar alarms. LIGNIN ENG. CO. Ltd. 4 Nov., 1969, No. 54012/69. Headings G4H and G4N.  A burglar alarm for a protected enclosure arranged to be pressurized by a predetermined air flow therethrough comprises a switch 10 associated with a time delay 19 so that an alarm 31 operates at a predetermined time after a variation in the air flow associated with switch 10. A flow of air through the protected enclosure is created by means of a fan 1 driven by the mains or from a floating battery. Reduction in air pressure in the region of the outlet 6 due to opening of a door or window results in a vane 7 opening switch 10, so as to release relay 17 which de-energizes the heater of a thermal delay switch 19 so that its contacts open after a predetermined period, releasing relay 32 and initiating a local or remote bell 31. Nullifying devices for initiated persons.-The time delay switch 19 has sufficient delay to enable an authorized person to enter the enclosure and nullify the system by dialling an appropriate code in inhibitor 33 so as to energize the appropriate points of a cross-bar matrix (not described in detail) and have to energize relay 37 and short circuit the contacts of the thermal delay switch 19. A reset button 39 is provided. The inhibitor 31 may be replaced by a key switch. Preventing incorrect operation.-A fuse F is provided, arranged to operate in the event of short circuit of conductors 14<SP>1</SP>. Modifications.-In Fig. 2 (not shown) long and short time delays are included, the latter preventing unwanted response due to temporary draughts &c. Manual test facilities and indicator lights are included. Signalling to and from a central station.- Fig. 3 shows part of a system in a central station and comprises a plurality of oscillators 102, each capable of producing a different frequency or code, but arranged so that oscillation is inhibited except when a core is set to an inward position by means of cam 104 driven by a motor. Each subscriber is provided with a decoder tuned to present a closed circuit only to the particular frequency or code from the central station. Each oscillator in turn transmits a signal over a common line but only one of the decoders responds to any particular signal; each decoder is associated with the alarm contacts so that when the cam 104 is directed towards an oscillator 102 associated with a subscriber having an alarm condition, the signal across resistor 106 will fail and an alarm 109 will operate and the motor will stop.

Title: Microinstruction controlled computer
IPC: G06F9/22
Filed: 1973-11-23
Abstract: 1456849 Data processing systems HONEYWELL INFORMATION SYSTEMS Inc 23 Nov 1973 [24 Nov 1972] 54383/73 Heading G4A A data processing system includes a memory (102, Fig. 1, not shown) for microinstructions, source selection circuitry 200, 202 (Fig. 4) for selecting one of a plurality of data sources under the control of part of a selected microinstruction and logic circuitry 204 for operating on the signals received from the seected source under the control of a further part of the selected microinstruction. As described, microinstructions may be of three types, the first being characterized by a "0" in bit position 14, bits 1-6 specifying a source, the second being characterized by a "1" in bit position 14 and "zeroes" in bit positions 1-6, the data source being a main memory address register (112) and the third being characterized by a "1" in bit 14, bits 1-8 specifying a source of an address in main memory (116). Bits 9-12 specify for all microinstructions the arithmetic/logic operation to be performed on the data and bit 13 is a test and modify bit used to determine inter alia if the result of the logic operation or the original data is to be re-stored. In selection circuitry 200 bits 0-3 are fed to a first level of multiplexers and bits 4-6 to a second level multiplexer so that data from the selected source, when bit 14 is "zero" is fed in inverted form through gate 218 (unless the arithmetic/logic function is "rotate" or "nothing" recognized by gate 220). If bit 14 is "1" and the function is not "rotate" or "nothing" the data from memory is fed in inverted form via gate 222. A subtract operation is recognized by gate 228 and controls an exclusive OR gate 226 to re-invert the data if necessary before it is fed to the logic circuitry 204. NAND gate 228 in source selection circuitry 202 recognizes "increment" functions and NAND gate 230 recognizes the "load" or "nothing" function to inhibit the second source data from serial register (122). Logic 204 performs the operation OR, AND, exclusive OR and add, the carry input being inhibited if the operation is not an arithmetic one. Carry logic 206 controls a carry flip-flop 256. Test and modify circuitry (Fig. 5, not shown) writes back the output of logic 204 into the source registers for some of the arithmetic functions if the test bit is "1". If the test bit is "0" or other of the arithmetic functions are performed the old data is rewritten into the source register.

Abstract: 1283372 Video recording and playback RCA CORPORATION 10 Nov 1969 [12 Nov 1968] 54924/69 Heading H4F [Also in Division G5] To ensure that a video signal recorded according to one of the three frequency modulation deviation standards (in which different frequencies are associated with black and white video signal levels) is passed through the corresponding standard record-reproduce circuitry during playback, the back porch (black level) portion of the played back FM signal is gated out and the frequency thereof compared with a standard frequency to derive a control signal which identifies the FM standard employed. This control signal is used to switch the played back FM signal to the correct one of the three record-reproduce circuits. To ensure that any new video information which supplements existing record and video information on a given record medium is recoded according to the same FM standard, the existing recorded information is played back to derive a control signal which switches into circuit the correct record-reproduce circuit before the new video information is recorded. The logic circuitry which produces the control signal is such that its last output control signal is maintained, even when there is no output from the comparison circuit, until a different output is derived from the comparison circuit.

Abstract: 1451915 Lamp failure alarms TEXAS INSTRUMENTS Ltd 29 Nov 1973 55387/73 Heading G4N [Also in Division H2] A lamp failure indicator for a motor vehicle has a first circuit (such as TR2, TR4 &c.) connected to respond if the voltage across a fuse F1 in series with the lamp L1 falls to zero and a second circuit (such as TR13, TR12 &c.) connected to respond if the voltage across the lamp L1 falls to zero, the arrangement being such as to produce an output signal (as at 8) in response to either circuit and being operative only when the lamp Ll is switched on. The transistors TR2, TR4 have their bases connected to points on a series circuit across the lamp supply at 3, 6 which includes transistors TR1 and TR9 with resistors R1 and R2 to produce a balance arrangement provided with a resistor R3 to provide sufficient unbalance to compensate for the normal small voltage drop across the fuse so that when this voltage drops to zero the voltage change between the collectors of TR2 and TR4 sets off the transistor TR6 of the three input Darlington circuit TR14, TR6, TR7, TR8 so that latter transistor TR4 conducts a substantial current from the terminal 8. A second series lamp L2 and fuse F2 have a fuse voltage responsive circuit with series transistors TR3, TR5 controlling the input transistor TR7 of the Darlington circuit. Diodes D2, D3 are arranged so that when a fuse blows and the voltage across a lamp L1 or L2 is zero a transistor TR13 of a long-tailed pair circuit (including TR10 and TR11) conducts to activate the other input TR14 of the Darlington circuit to provide an output signal.

Abstract: 1,201,507. Continuous casting. LCMA MACHINE MFG. CO. Inc. 7 Dec., 1967, No. 55774/67. Heading B3F.  For casting metal from a trough tundish 30 to form strip 12, a vertical mould has two large walls (each comprising a copper plate 40, or 52, held by bolts 41, or 53, on a backing plate 37, or 49, with a coolant passage 42 therebetween) each driven to swing about pivots at the ends of a horizontal enlargement 39, or 51, along its upper end, so that periodically the bottom ends approach each other and the walls converge downwardly to enhance the cooling and to work the hot metal before it is withdrawn by rolls. The vertical ends of the mould are closed by narrow copper plates 60 urged by springs (61) against the edges of the large, swinging walls. A gear 120, through a synchronizing gear (122) drives a gear 121 so that horizontal shafts 70, 100 are rotated and eccentric portions 73 (103) thereof each reciprocate a spring-loaded thrust link 75, 80 (105) to swing the mould walls. The plate 40 swings to a position 40a and back but the swing may be limited by adjusting a screw 92. Coolant passes out between the tapered lower end 44 of the plate 40 and the oblique lower end 38 of the backing plate 37. The other large mould wall is similarly arranged. Molten metal enters the tundish 30 from a pipe 144 by way of horizontal slots 146 in a spout 145 extending along the tundish trough. The tundish comprises a metal shell 131 and bottom frame 140 lined with refractory 134 and is mounted on bolts 137, 138 at its corners to be urged by springs 141 against the top edge of the mould. The slight movement of the top edges of the larger mould walls permits lubricant to be forced between the mould and tundish 30 into the mould. The tundish and mould-driving elements are mounted on four brackets (26), 27, 28 (29) which bear stub-shafts (35, 36 and 47, 48) on which the large mould walls swing. The brackets are bolted at either side of an opening 10 in a base 11.

Filed: 1966-12-21
Abstract: A metal A such as Ni or Co-Ni is deposited from a reducing bath on to a body B comprising a semi-conductor or a metal more noble than A, the surface of which is seeded with a metal C e.g. Al equally or less noble than A by suspending particles of the metal C in the reducing bath e.g. by stirring the bath or heating it to its boiling point. The bath may be a solution of (1) NiCl2, NaH2PO2, Na citrate and NH4Cl; or (2) CoCl2, NiCl2, Na glycolate and NaH2PO2. For example, semi-conductor wafers e.g. discs of bismuth telluride, selenide or antimonide, cleansed with sand jets and boiled in methanol, are introduced into the reducing bath in which is suspended Al powder of grain size 15.10-3 mm to produce a coating thereon of metal A 3.10-3 mm thick.  After again boiling in methanol, the coated wafers are dried and heat treated at 120 DEG C.  The wafers were then divided into pieces to form legs of thermocouple elements and the process is repeated to provide the legs with a second coating of metal A 1.10-3 mm thick.
