Title: Magnetic core logic circuits
IPC: H03K17/82
Filed: 1961-11-27
Abstract: 929,744. Magnetic logical circuits. AMP Inc. Nov. 27, 1961 [Dec. 7, 1960], No. 42305/61. Class 40 (9). A magnetic OR or AND circuit comprises input cores 11, 13 coupled by transfer windings 22, 32 to an output core 16, each core being of the multi-aperture type having " clear," " set " and " prime " dispositions of the remanent magnetic flux. Initially, a pulse in an advance winding 38 brings the input cores into the " clear " state in which the remanent flux is unidirectional about the main apertures 1, 2. Input signals are then applied to windings 18, 28 passed through receive apertures 20, 30 in the input cores, and the core fluxes are redistributed into the " set " state in which local fluxes are established about the receive and transmit apertures 20, 30 and 24, 34. The " set " state local flux is in a direction opposite to the main aperture flux in the limb of each core between the transmit and main apertures. The input cores are next brought into the "prime" " state by a pulse or steady bias applied to conductor 42 so that the flux about each transmit aperture is reversed. Subsequently, the input cores are cleared by an advance winding pulse and outputs induced in the transfer windings. If both input cores produce outputs, the cumulative effect of the transfer currents through transmit aperture 26 switches the output core to the " set " state This core in turn produces an output in winding 36 after priming and the application of an advance pulse to winding 40. For operation as an OR circuit either transfer current from the input cores is effective in setting the output core.

Abstract: 997,507. Cold separation of gas mixtures. COUCH INTERNATIONAL METHANE Ltd. Nov. 4, 1963, No. 43416/63. Heading F4P. Natural methane is separated from a substantial carbon dioxide content by cooling and partially liquefying compressed feed gas from a line 1 in a first heat absorber 5 charged with cold separated carbon dioxide, fractionating in a column 7, partially condensing effluent gas containing a small amount of carbon dioxide in a second heat absorber 8 also charged with cold separated carbon dioxide, recompressing at 10, cooling at 8 and expanding at a valve 11 the gaseous fraction thereby freezing out the carbon dioxide content, combining said frozen out constituent with the bottoms of the reboiler 2 of column 7 and using the combined stream as coolant in said heat absorbers 5, 8. Preliminary cooling of the feed gas is effected by passage through the reboiler 2 traversed by a separate ammonia cycle followed by passage through a heat exchanger 3 traversed by reversely flowing separated methane and carbon dioxide products and by passage through an ammonia devaporator 4 which is included in the circuit containing reboiler 2, a compressor 18 and an aftercooler 19. Solid carbon dioxide resulting from expansion at valve 11 is collected in a first flash chamber A which when full is switched with a second chamber B in the liquid carbon dioxide line leading from reboiler 2 in which the solid carbon dioxide is dissolved. The combined stream is further cooled at 13 and is expanded at valve 15, 16 into heat absorbers 5, 8 forming a slurry of solid carbon dioxide in a carrier liquid, e.g. toluene therein.

Title: Improvements in and relating to arithmetic devices
IPC: G06F11/16
Filed: 1959-12-24
Abstract: 898,594. Digital calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 24, 1959 [Dec. 29, 1958], No. 43832/59. Class 106 (1). An arithmetic device includes means for performing a first arithmetic operation on two numerical quantities represented by input signals and producing an output, means for performing the inverse operation to the first on two numerical quantities represented by one of the input signals and the output and means producing a check signal when the result of the inverse operation is the number represented by the other input signal. The circuit of Fig. 3 shows number registers 2 to 4, an adder 5, a subtracter 6, an AND circuit 7 and addition and subtraction gates 8, 9 respectively. When gate 8 is opened, the sum A + B = T is formed, together with the difference T - B = A*. If A = A*, a check signal issues. When gate 9 is opened, the difference T - B = A is formed, together with the sum B + A = T*. If T = T*, a check signal issues. Fig. 4 shows the application to a parallel multi-order device having like parts numbered as in Fig. 3 and using exclusive-or circuits designated V. The registers comprise flip-flops each storing a binary digit. For addition numbers are entered into registers A and B. If for any order A and B both store 1, and circuit 11 activates carry line 34, if one of A, B are 1, circuit 13 is activated and unless there is a carry from the lower order, activates circuit 14. If there is a carry, circuit 14 is inhibited and and circuit 12 is activated to produce a carry. Thus output from circuit 14 is high if the result of the addition is 1, low otherwise. The output is applied directly to a gate 23 and inverted to a gate 24. An add signal on line 32 is gated to set flip-flop 4 according to the result of the addition. If the addition has been correctly performed the state of the " 0 " output from flip-flop 4 is that of the output from circuit 14 inverted. These lines provide inputs to circuit 27 which when operated by correct addition provides one input to AND unit 28. T-B is then performed in subtractor 6, the output of circuit 22 being high if the result is 1. This output is compared with the 0 output of the A flip-flop 3 and, if it is dissimilar, circuit 26 operates to provide the other input to and unit 28, an output from which indicates that addition in the lowest order is complete and correct. All such and units provide an input to and gate 29 which gives an output when the operation is completed for all orders. For subtraction numbers are entered in the T and B registers and their difference entered in the A register when a subtract signal appears on line 33. A + B is then formed and if this is equal to T half-adder 27 energizes one input to and circuit 28, the other input having been energized by correct performance of the subtraction.

Sample 7 to be tested is subject to an alternating magnetic field from a hollow single layer solenoid 5 energized by step-down transformer 1 having a single winding secondary 4. The magnetization induced in the sample is measured by pick-up coil 6 connected via amplifier 10 to a double pole switch 11 which connects the pick-up signal either through an electronic switching circuit 12 or differential amplifier 13 to integrator 14, the output of which is fed to a meter 15 and via phase corrector 16 to vertical deflection plates 17 of CRT 18. The solenoid 5 field strength is measured by winding 8 connected to an integrator 34 whose output is connected to meter 35 and via phase corrector 36 to the horizontal deflecting plates 37 of the CRT, on which is thus displayed the hysteresis loop. In order to compare the measured values of the sample 7 with a standard a twin track magnetic drum 19 is used which is rotated by a synchronous electric motor 23 driven at the same frequency as the A.C. applied to primary winding 2 of transformer 1.

The bearing 4 comprises a flanged pintle 21 entering a blind hole 1a in the shaft 1 and resting on a ball 23 on a plate 22 of hard material. Oil from a pressure source 26 enters a central duct 24 through a radial duct 25 and escapes through radial ducts 27, orifices 28, 29 and a bore 20 in the skirt 1b of the shaft 1. Thereby the shaft 1 is supported by the upper face of the pintle 21 through the medium of an oil film and is centred by another oil film around the pintle and within the skirt 1b. The air bearing 5 comprises two annular members 31, 32 receiving the shaft 1 and formed with an annular chamber 34 receiving compressed air through a pipe 35.
