Abstract: 902,402. Circuits employing bi-stable magrietic elements. STANDARD TELEPHONES & CABLES Ltd. May 22, 1959 [May 23, 1958], No. 16663/58. Class 40 (9). A magnetic storage matrix has each row or column of storage cores 2, Fig. 1, disposed in close proximity around the periphery of an associated large switching core 1, the output winding 11 of the switching core being wound so as to pass through the various storage cores with the winding turns distributed evenly between the storage cores. In this arrangement read-out of a row or column of cores is effected by reversing the state of the switching core, the output signal then developed in the winding 11 being sufficient to reverse the state of the associated storage cores. The core assembly may be formed by inserting the cores in an apertured insulating disc 13, Fig. 2 (not shown), which may be provided with core-retaining plates 17, 18, Fig. 3. Alternatively the cores may be located between two recessed units 19, 20, Fig. 4, or may be inserted in a single recessed unit, Fig. 5 (not shown), the recesses of which are of greater depth than the cores. In the latter embodiment the unit is formed of thermoplastic material and is subjected to heat treatment after the cores are inserted to form retaining lips. A further assembly is mentioned in which the cores are placed on an adhesive insulating tape and then covered with a further tape. The wiring is then pushed through holes in the tapes which may comprise a number of core assemblies formed on one long strip of tape. An alternative arrangement is shown in Fig. 6 in which the switching and storage cores are formed from a single block of ferro-magnetic material with a rectangular hysteresis loop, the storage cores 26 being attached to the switching core 25 by narrow strips of material 27. Application of the arrangement to telephone metering equipment as disclosed in Specification 902,401 is also described, Fig. 7 (not shown).

Title: Photographic silver halide materials
Inventor: SEYMOUR MERRILL WILMER
IPC: G03C1/46
Filed: 1969-04-01
Abstract: 1,269,071. Photographic silver halide colour material. EASTMAN KODAK CO. April 1, 1969 [April 1, 1968], No. 16867/69. Heading G2C. A photographic material comprises a support carrying at least two superposed silver halide layers sensitive to different spectral regions or separated by a filter layer whereby each layer is adapted to be separately imagewise exposed and the silver halide emulsion layer or layers not contiguous to the support contains a developmentinhibitor-releasing (DIR) coupler and has a finer grain silver halide emulsion than that of the emulsion contiguous to the support. All the silver halide emulsion layers may contain non-diffusing dye-forming couplers, the coupler in each layer forming a different colour dye from those in any of the other layers. The DIR coupler preferably releases a diffusible mercaptan development inhibitor. Many examples of couplers are given. The filter layer is preferably bleached during photographic processing and may be a layer of yellow Carey-Lea silver (EX7). There may be a hydrophilic colloid layer between each silver halide emulsion layer to delay diffusion of the photographic processing solutions. Preferably two silver halide emulsion layers are used - a silver chlorobromide emulsion containing the DIR coupler and a silver bromoiodide emulsion. One of these emulsions is preferably green-sensitized and the other is unsensitized, which embodiment yields a black and a coloured image (see EX2). These materials are useful in aerial reconnaissance.

Title: Improvements relating to electrical measuring apparatus
IPC: G01R15/14
Filed: 1953-06-18
Abstract: 741,392. High voltage measurements using capacitive voltage dividers; electric capacitors. HIVOLT, Ltd., and BRUCE, F. M. June 18, 1954 [June 18, 1953], No. 16888/53. Class 37. The very high A.C. voltage to be measured (e.g. 100 kilovolts) is applied between concave electrodes 1, 2, Fig. 2, and a proportional low-value measuring voltage (e.g. 1 volt) is tapped-off a probe electrode 15. and applied to a cathode-follower valve voltmeter, Fig. 3. The geometry of the electrodes 1, 2 provides a high degree of screening from external stray fields; also the rolled-over rims shown tend to reduce corona discharge or arcing. The electrode 2 adjacent probe 15 is mounted on a pedestal 5 which at 18 encloses the valve 20 and input &c. components shown to the left of the chain line in Fig. 3. The power pack, calibration, &c. components shown on the right of the chain line are contained in the measurement and control unit 8, Fig. 1, and the considerable length of the flexible connecting cable 7 per-' mitted by the use of the cathode follower valve 20 shown (high input and low output impedance) means that unit 8 may be located at a safe distance from the high A.C. voltage applied to electrodes 1, 2. The 3-position switch 12 in co-operation with rheostats 25, 27 and k.v. reading meter 9 provides for adjusting the anode and filament voltages of valve 20 to the correct value each time a measurement is made. The electrodes 1, 2 are of sheet metal and mounted on an insulating column 3 which encloses and holds the metallic probe electrode 15 and sensitivity is varied by moving the column 3 vertically and thus also the probe 15 and locking the column 3 by means of grub screw 33.

Title: Data processing apparatus
IPC: G06F12/06
Filed: 1977-04-27
Abstract: 1527316 Data processing INTERNATIONAL BUSINESS MACHINES CORP 27 April 1977 [3 May 1976] 17490/77 Heading G4A A data processor incorporates on a single semiconductor chip (Fig. 2a-c), an ALU (22), an internal control store (18), I/O registers (93, 94), local memory (30), memory address registers (191, 192) to access an external memory and a control store address register (28, 29) which in dependence on a first field of the address accesses either the internal control store (18) or external control storage. The 8 bit registers (28, 29) are connected to operate as an 11 bit counter to address the internal store or as a 15 bit counter to address the external store, the most significant bit of one register (29) determining which control store is selected. The variable address length is accommodated by modifying the carry between bits 4, 5 of the high order register. The ALU (22) performs inter alia adidtion, basic logic, complementing and rotation. An operation is latched into AOP register (32) and this operation performed until the register is reloaded. A read-only store (34) consists of 32 mini mask words, each of 18 bits, which when accessed provide 8 bits for the AOP register (32), 8 bits as the B operand and 2 bits for a skip instruction. Logic and arithmetic operations are effected by selective control of gates (G1-G6, Fig. 7, not shown), in the arithmetic unit. Each processor having access to the external memory includes one stage of a ring counter, a shift bit in setting a flip-flop (151, Fig. 10, not shown) which, if a memory request is present on a line (169) to set a nip-flop (155), results in a request out signal from gating (181, 182). Otherwise the shift bit passes via flip-flop (161) and shift bit-out line (145) to the next memory control. The processes may be divided into groups controlled by a further ring counter (200, Fig. 12, not shown) with outputs from, e.g. the first and third stages of the counter being connected to the same group of processes to give them enhanced priority.
