Title: Read only memory
IPC: G11C17/00
Filed: 1974-05-17
Abstract: 1456608 Read only memories INTERNATIONAL BUSINESS MACHINES CORP 17 May 1974 [23 Aug 1973] 22200/74 Heading G4A A read only memory comprises an array of bit locations, each characterized by a first source electrode 55 (Fig. 2), a sense line 90 and, if a "1" bit is stored in the location, a control gate 26, read out being effected by charging a selected source electrode 55 (under the control of source decode circuits) and a selected gate 26 (under the control of gate decode circuits) to conduct an output charge to the associated sense line connector in the drain electrode 90. As described, each bit location in the array comprises an FET, row source electrode 55 and drain electrode 90 being formed of N-type regions in a silicon substrate having an oxide coating. A column gate is formed by removing the coating between electrodes 55, 90 and applying a metal pattern 28 which when a positive charge is applied to it induces a negative charge in the P-type material between regions 55, 90 to create a conductive path, the output charge transferred to the sense line setting an associated latch to indicate a binary "1". Column select.-This is effected by a 7 -bit input address converted by logic circuitry (42, Fig. 5a, not shown) to true and complementary signals which are selectively fed to 128 gate decode circuits (50) to energize one of the column lines (33). Row select.-The array may be addressed either as a whole in which case the input bit on one of the row address lines (71, Fig. 5a, not shown) selects the upper or lower half or both halves of the array may be simultaneously addressed in which case this address line (71) is grounded. Each half of the array is arranged in three segments, each having four sections. The four sections in both halves may be simultaneously addressed by applying a positive signal on two address lines (58, 71). A segment is selected by the bits on five address lines (75) being fed to three chip decode circuits (83) to deliver a signal on one of three lines to NOR gates (68) also receiving an address signal (56, 57) the output signals (69) from the NOR gate (68) being connected to four sense lines (55, Fig. 5b, not shown) each connected to two rows of the read only memory so that either 8 or 16 bit locations may be addressed. Removal of charge.-The array includes an additional column (93, Fig. 6d, not shown) of bit locations each having a gate. At the end of each memory cycle a pulse is applied to all the NOR circuits (68) to render all the transistors conductive to provide a path to ground for the elimination of any charge on a sense line before the next cycle.

Title: Telephone installations in which a number of junction lines are available to a greater number of subscribers for calls to an exchange
IPC: H04Q3/00
Filed: 1946-07-26
Abstract: 637,297. Automatic exchange systems. GFELLER AKT.-GES., C. July 26, 1946, Nos. 22354 and 22355. Convention dates, July 26, 1945, and Sept. 4, 1945. [Class 40 (iv)] Cross-bar switches are provided at both ends of the junctions L1 between an exchange EX and an automatic satellite (non-exchange) DP. Each cross-bar is associated with an eight-bank step-by-step switch and the two switches are so linked by a control wire CH that relays Ep, Ep1 always act together and the switches perform similar operations in step. The stepby-step movements of the two switches are isochronous. The cross-bars are of a type in which both vertical and horizontal magnets are operated in accordance with the lines to be connected and in which the connection is not made until the vertical magnet is released. The connection is held mechanically when both magnets have released. Start relays An1, 2 are each common to the two or more subscribers of a group such as Te1, 2 and Te3, 4. Call from Te2 to exchange. When Te2 lifts his receiver, An1 operates to mark contacts Sd1, 2 and is followed successively by relays Sr, Ep, Ep1 and switch magnets M, M1. The switch magnets have interrupting contacts m and ground on contacts 2 to 6 of Sh and Sh1 steps the switches till they come to rest at the contacts 7. When started again by operation of Ep, the switch stops on the contact 1. The calling group is marked on contacts Sd2 or Sd3 (in this case Sd2), and at these contacts Sr and Ep operate and Gr1, Gr1<SP>1</SP> follow over Sc, Sc1 to prepare banks Sa, Sa1 and Se, Se1 corresponding to the calling group. When a junction is free, the test relay X1, X2 or X3 at the exchange is not operated and the corre. sponding contact 4, 5 or 6 of Sd1 is marked. When the switch finds the first free junction (say on contact 4) Sr1, Ep1 and Ep operate and the vertical magnets H1, H1<SP>1</SP> follow and hold. Both switches stop on contact 7 and are started again together by operation of Sy over Sg7. The particular calling line of the group is marked on contacts 8 to 21 of the appropriate bank Se or Sf (in this case 9 of Se) and the corresponding horizontal magnet T2 operates and holds when the marking is found. If a relay S has not operated meantime to signal a fault, the switch steps on to contact 23 where relays K, K1 operate over Sc23, Sc<SP>1</SP>23 to prepare circuits for relays Hb, Hb1 which operate over Sg24, Sg<SP>1</SP>24 to release the vertical magnets H1, H1<SP>1</SP> and thereby to complete the connection. At Sg25, Sg<SP>1</SP>25 relays HC, HC1 operate to release the horizontal magnets. As the switches step round slow release relays V1, V2 and V1<SP>1</SP>, V2<SP>1</SP> remain operated. If a switch stops, relay S or S1  operates and disables Hb and Hb1 so that the vertical magnets are not released to complete the connection. A rectifier valve Ve1 protects the line relay Pr1 from a starting potential applied to a group relay An1<SP>1</SP> by any other line relay Pr2 of the group.

Abstract: 403,598. Fuel-injection pumps. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. Aug. 14, 1933, No. 22624. Convention date, Aug. 15, 1932. [Class 102 (i).] In a fuel-injection pump in which helical edges control both the suction port and a relief port, the timing of the commencement of injection is varied, without altering the amount of the charge, by rotation of the plunger, while the timing of the opening of the relief port, and hence the amount of the charge, is varied by rotation of a part of the cylinders. The helical edge 21 of the plunger co-operates with a suction port 12 and the timing of injection is varied by rotating, by means of a rack 32, a sleeve 28 which engages the plunger. An axial passage 23 in the plunger terminates in a relief port 24, which co-operates with a helical edge 22 on a sleeve 8, and the timing of relief is varied by rotating the sleeve 8. Alternatively a helical edge on the plunger may co-operate with a relief port in the sleeve 8. The sleeve 8 is formed with a shoulder which seats on a shoulder in a stepped guide bush 7, and both the sleeve 7 and bush 8 are positioned axially by the upper portion 11 of the cylinder, which is secured in position by the valve carriers 15 and the nipple 17. The sleeve 8 may be formed with teeth engaged by a rack projecting through an aperture in the bush 7, or, as shown, the sleeve 8 may be engaged by a sleeve 34, surrounding the bush 7, and rotatable by means of a rack 32. In the latter case the sleeve 28 surrounds the sleeve 34 and both are secured by a washer 29 engaged by the plunger return spring 6.

Title: Motor vehicle magnetic gauge circuitry
IPC: F01M11/10
Filed: 1973-05-14
Abstract: 1359129 Measuring pressure and temperature electrically FORD MOTOR CO Ltd 14 May 1973 [22 May 1972] 22825/73 Heading G1N In magnetic gauge circuitry for a motor vehicle, e.g. for indicating engine oil pressure or temperature, a switch 58 is interposed between the source of energy 44 and the gauge, and means are provided for delaying for a predetermined time the change of state of the switch when the vehicle ignition switch 52 is operated to energize or de-energize the gauge. As shown, oil pressure is indicated by a gauge 64 which includes a resistor 80 responsive to oil pressure and coils 36', 38', 40' the current through which determines the position of a pointer, and engine temperature is indicated by a gauge 66 which includes a resistor 90, e.g. a thermistor, responsive to engine temperature and coils 36", 38", 40" which are similarly associated with a pointer. The coils and pointer may be arranged as described with reference to Figs. 1 and 2, (not shown). The switch 58 and delay means are composed of a bi-metallic strip 68 surrounded by a heating coil 70, and a pair of contacts 56, 60 connected to the energy source 44, ignition switch 52 and gauges as shown. For oil pressure indication, when the ignition switch 52 is opened to switch off the engine there is a delay before the contacts 56, 60 open, thereby allowing the gauge pointer to return toward the zero mark during the delay. For temperature indication, when the ignition switch is initially closed, current is immediately supplied to coil 38" and resistor 90 but only to coils 36" and 40" after a delay. During this delay, therefore, the gauge gives a maximum reading to indicate operability. When the ignition switch is subsequently opened, the delay introduced by switch 58 allows the pointer to return toward zero reading.
