Title: Driving arrangements for a three-dimensional magnetic core matrix
IPC: G11C11/06
Filed: 1962-02-02
Abstract: 940,634. Magnetic pulse storage devices. NATIONAL CASH REGISTER CO. Feb. 2, 1962 [Feb. 23, 1961], No. 4170/62. Headings H3B and H3T. An electrically three-dimensional matrix is provided with a three to one selection ratio by passing a current ZI say through all cores of a selected YZ plane a current of I through all selected X lines and a current of -I through all other X lines. In the embodiment described, a 2500 X 4 X 13, X X Y X Z matrix, the YZ read wires are energized through a set of read drivers R1-R50 and read grounders R<SP>1</SP>1-R<SP>1</SP>50 which are selected by two 5 x 10 switching matrices 8 and 8<SP>1</SP> which also operates write drivers W1-W50 and write grounders W<SP>1</SP>1-W<SP>1</SP>50. This method of YZ plane selection is more fully described in Specification 940,635. The X line drivers are actuated from flip-flops L1 and L2 through gates as shown in Fig. 2, the flip-flops LL1 and LL2 actually holding the information to allow L1 and L2 to be reset before the end of the operating cycle. The drivers XD 1-1 normally produce a current in one direction, but on application of a pulse the direction is reversed. The driver receives a pulse when G1, E w , M<SP>1</SP> and G1<SP>1</SP>E R  is true, where G1 is the condition for line X1 to be selected, E w  is the write pulse, M 1  is the condition for " 1 " to be written, G1<SP>1</SP> is the complement of G1 and ER is the read pulse. The driver circuit is shown in Fig. 3. As transistors 39 and 41 are normally conducting, current flows from the D.C. source out through wire 341 and back through wire 32<SP>1</SP>, but, on applying a pulse to the transformer, transistors 39 and 41 are cut off and transistors 38 and 40 are cut on, thus changing the direction of the current. The inductor 36 and resistors 35 and 37 limit the output current and the voltage between points 31 and 33 is limited by diode 51 and Zener diode 52. Diodes 53 and 54 protect the transistors from inverse voltages. Information may be supplied to the matrix in either series or parallel form.

Title: Digital data apparatus
IPC: G06F3/048
Filed: 1973-01-29
Abstract: 1394652 Data processors HEWLETTPACKARD CO 29 Jan 1973 [14 Feb 1972] 4339/73 Heading G4A A digital data processor includes a number of storage registers and associated selector switches which cause the data in a currently selected register to be displayed on indicator lamps connected to a display register. The state of any bit of the displayed data may be changed by operation of a corresponding switch without causing alteration of the data in the selected register. When a new register or function is selected by operation of a selector switch the data on the display register is read in to the last-selected register. The operation performed by the circuit described depends upon which of the registers is the currently selected one and which the newly selected one. The arrangement disclosed uses 5 registers denoted T, A, B, M and P, in addition to the display register. Suppose, for example, that the currently selected register is the T register and that consequently latch 42 is set and the display shows the content of the T register. If now a new register is selected, e.g. B by closing switch 29, the circuit operates under the control of section 133 to set the corresponding current latch 36. After a preset time section 133 causes the data in the display register to be returned to the currently selected register specified by the set latch 42, i.e. to T. The content of T is then read in to an address in a core or other memory 129, the address being specified by the content of the register M. This being done a signal from section 133 causes B register latch 46 to be set and the previously set latch 42 to be reset, i.e. the latches are updated prior to a new register being selected. The latch 46, now set, causes the content of the B register to be displayed. Had the new selected register been T, the same as the currently selected register, rather than one of the other registers, a comparator 60 would have detected this fact and prevented the transference of the content of the display register to the current selected register T. The content of T would have been stored in memory 129, as before, under control of section 133 and the data subsequently read to register T and the display from the same address, because the new selected register was T. Algorithms indicating the five possible operating modes are given in Figs. 4-8 (not shown).

Title: Improvements in or relating to variable inductance devices
IPC: H01F21/00
Filed: 1925-02-17
Abstract: 252,236. Igranic Electric Co., Ltd., and Wright, S. R. Feb. 17, 1925. Wireless tuning-apparatus, adjustment devices for; inductances.-In variable inductance devices of the kind comprising main coil units relatively movable for coarse adjustments and a vernier coil unit movable for subsequent fine adjustments, the main coil units are arranged one within another and the vernier coil unit is located within the inner of the main coil units. In a variometer constructed as described in Specification 235,654 and comprising a coil 1 in the form of a hollow spherical zone rotatable about a diametral axis within a similar coil 2 within a protective tube 5, a vernier coil 19 consisting of three turns of stiff wire is mounted within the coil 1 and is rotatable about an axis at right angle to, and intersecting, the axis of rotation of the coil 1 bv disc-and-wheel friction gearing 22, 23 and a central shaft 24 passing through the hollow shaft 13 controlling the coil 1. All three coils 1, 2, 19 are in series between two terminals 29, 42, the coils 1, 2 being each in halves above and below the axis of rotation and the circuit passing through the upper half of the coil 2, the lower half of the coil 1, the soil 19, the upper half of the coil 1 and the lower half of the coil 2 successively. The coil 19 is carried on an insulating shaft with stub axles 18 serving as electric connections and engaging brackets on the insulating ring 3 supporting and connecting the two halves of the coil 1, a similar ring 4 supporting the coil 2. The shaft 13 may carry a peep-hole indicator X as described in Specification 240,983. The terminals 29, 42 serve as bolts for strips joining the ends of a flat sheet bent to form the tube 5.

Abstract: 548,479. Coating metals ; electrolysis; paints. YORKSHIRE DYEWARE & CHEMICAL CO., Ltd., BEDFORD, J. G., STOREY, R. C., and KIRKHAM, R. W. D. April 3, 1941, Nos. 4450 and 8504. [Class 82 (ii)] [Also in Groups III and XXXVI] The surfaces of magnesium or magnesium alloys are provided with a coating of a film of dehydrated magnesium phosphate. The metal is treated with a solution containing phosphoric acid or a derivative such as phosphotungstic acid to form the film of the phosphate which' is then heated, e.g. to 150‹ C., to dehydrate it. The treating solution may be an aqueous solution of phosphoric acid containing a monohydric alcohol or a surface tension-reducing agent such as a sulphated fatty alcohol or the film of phosphate may be formed by electrodeposition in a phosphate bath. The coated metal may then be treated in a further bath for the purpose of colouring the film, i.e. a dyeing bath, or making the latter water repellent, e.g. in a bath of linseed oil containing 0.1 per cent. of cobalt linoleate, either in the cold or at elevated temperatures. The colouring and the water-repellent properties may also be produced by the incorporation of suitable substances in the phosphate bath. Magnesium castings after phosphating and heating at 160-180‹ C. for half an hour may be painted with a zinc chromate or magnesium pyrophosphate paints prepared bv milling together 180 gms. linseed oil, 25 of zinc chromate or magnesium pyrophosphate, 45 of zinc oxide and 0.2 of cobalt linoleate.

Title: Signal comparator

IPC: H03K5/24
Filed: 1962-02-06
Abstract: 987, 071. Voltage comparators. STANDARD TELEPHONES & CABLES Ltd. Feb. 6, 1962, No. 4460/62. Heading G1U. [Also in Divisions H3 and H4] A voltage comparator circuit, particularly for comparing the D.C. output signal of a radio altimeter with a monitor receiver signal, gives an indication when the allowable percentage difference between the two signal amplitudes is exceeded. The altimeter and reference receiver signals are applied at 3, 4 to respective choppers 1, 2 which amplitude modulate respective pulse trains, derived from a multivibrator drive circuit 5 and which are interleaved and applied as a single pulse train to an AGC amplifier 6, a voltage level selector 7 which slices a selected voltage from each pulse and a counter 8, the arrangement being such that the selector output is in the form of a further pulse train the recurrence frequency of which varies according to the amplitude difference between the input signals. The D.C. output of the counter varies in correspondence with the amplitude difference and operates an indicator if the permitted difference is exceeded. When the interleaved input pulse signals are of equal magnitude, the input at 11, 12 to the voltage level selector (Fig. 14) is as shown in Fig. 6. The dotted lines X, Y indicate the permitted difference and the A.G.C. in amplifier 6 ensures that the total voltage excursion of the pulses is 20. v. A clamping diode 13 ensures that the voltage at the junction of 10, 13, 15 is at zero potential when the input goes negative and remains at a substantially constant positive potential (+20 v.) when the input goes positive. The anode of diode 14 is held at a potential, the selection level, (e.g. +18 v.) by setting the tapping on potentiometer 16 to a position determined by the maximum permissible difference (10% in this example) between the two signal voltages. Diode 14 will therefore conduct as long as its cathode potential is less than 18 v. When the input signals are equal the output at 18, 20 is as shown in Fig. 7, and corresponds to a pulse train of amplitude 2 v., this train being of the same frequency as the input. If however, the input to the selector is as shown in Fig. 11 where the "reference" pulse and the "altimeter" pulse amplitudes differ by more than the permitted amount, the output at 18, 20 will be as shown in Fig. 12 since diode 14 conducts in the presence of the smaller pulses, so resulting in a pulse output train of half the frequency of that shown in Fig. 7. The counter output will thus also be halved and allow the indicator to operate. More than two input signals may be compared. Specification 914,679 is referred to.
