Title: Multi-microprocessor unit on a single semi-conductor chip
IPC: G06F9/28
Filed: 1975-09-11
Abstract: 1498145 Data processing BURROUGHS CORP 11 Sept 1975 [26 Nov 1974] 37353/75 Heading G4A A plurality of processes share, sequentially, a common arithmetic unit 33 and control logic 40 which includes a read-only memory and receives in sequence, via a register 35, from a read-only microprogram memory encoded microinstructions for the different processes. There are common scratch pad memories 31, 32 and each process has respective set of registers 34-38, 42-44, the address for the microprogram memory being provided by page and byte registers 37, 36. The apparatus shown in Fig. 2 may be formed on a single semiconductor chip and a number of such chips may share a random access memory (13, Fig. 1, not shown), each chip being connected to respective peripherals and a respective microprogram memory (12). Each process may be allocated one page of registers in each of scratch pad memories 31, 32, memory 32 being divided, for four processes, into four pages each of four registers, and memory 31 being divided into 24 registers such that each process has unique access to five registers, shares access to a further register with one other process and shares access to two other registers with all the other processes; the respective page number for the memory 31 is set in register 44. The scratch pad memories 31, 32 may be used for special purposes in which a page of memory 31 is combined with a page of memory 32 to provide addresses for the shared random access memory or the respective microprogram memory or to store two levels of return addresses when executing jump instructions. When a jump is to be executed the new page number is entered into a register 38 while the jump instruction is being fetched. The register 42 is used to store the state of the process while the other processes have access to the common resources.

Title: Improvements in teaching machines
Inventor: GEORGE FRANK HONYWILL
IPC: G09B7/08
Filed: 1964-09-12
Abstract: 1,117,094. Educational appliances. SCIENTIFIC SYSTEMS Ltd. 6 Dec., 1965 [12 Sept., 1964], No. 37398/64. Heading G5G. A teaching machine includes a programmed web having a plurality of frames arranged in sections, each section having at least a first and last frame, the web being adapted to be driven forwardly by a motor when one of a plurality of parallel circuits is completed by actuation of a manually controlled switch. A switch associated with the web (there being one for each circuit) is adapted to interrupt its circuit to de-energize the motor and halt the web when an aperture in the web corresponding to the circuit is located opposite its associated switch, and the last frame of each section is apertured to correspond with each of the switches associated with the web. As described the web is carried by two spools and is driven by two electric motors which move the web through the machine forwardly and rearwardly in response to depression of switches, and brushes adapted to contact the web protrude through apertures to contact brass bushes, thus completing electric circuits which cause de-activation of the motors. The web has apertures 101-104 corresponding to four possible answers to a question. A first frame 96 carrying information, a question and four answers, is positioned under a viewing window and a student selects an answer by pressing a corresponding switch (A-D). A relay 59 is activated and a motor 15 is driven to move the web through the machine until a frame having an aperture corresponding to the selected answer passes the appropriate brush (electrically represented by switches a-d). Closure of the appropriate switch (a-d) causes a relay 59 to be de-energized and thereby halts web movement. Upon selection of an incorrect answer a student may be instructed to reverse one frame by depression of switch E, a relay 76 thus being energized and causing a motor 16 to be driven. This motion is halted by one of the brushes protruding through an aperture in the web. A further instruction to return to the frame including the question (i.e. frame having apertures at positions corresponding to all the answers) is effected by depression of a switch X, and reversing motion is not halted until all the brushes contact the brass bushes (i.e. until all the switches a-d are closed). The machine includes a resetting switch R, a lamp 28 for illuminating the web, and an error counter 94 on which is indicated the number of times the web is reversed. The switches A-D, E, X and R are mechanically interconnected so that depression of one releases any previously depressed switch.

Abstract: 1,116,361. Fluid filter elements. DOULTON & CO. Ltd. 18 Aug., 1966 [7 Sept., 1965], No. 38174/65. Addition to 1070936. Headings BID and BIT. [Also in Division B5] A filter element of sintered polytetrafluoroethylene incorporates an integral reinforcing element, either at or near its surface or well embedded, which does not contribute to filtration. The reinforcement may be a random mat, woven natural or synthetic textiles, glass or silica fibres, wire coated with plastics or glass, woven or welded mesh of stainless steel. When the reinforcement is near the surface it may be pressed hot into the sintered plastic, applied cold and bonded by subsequent heating or pressed into the plastic which is first softened by solvent. Or a reinforcement is placed in a mould and the PTFE powder sintered around it, to make an element of the well embedded kind. Fig. I (not shown) illustrates a prior art filter tube, reinforced by a separate internal stainless steel helix, coated with P.T.F.E., the end of the tube being clamped between two parts of an adaptor. A particular example of the present invention is a tubular sintered P.T.F.E. element closed at one end with an embedded stainless steel mesh reinforcement (dimensions given).

Filed: 1967-08-19
Abstract: 1,144,258. Grinding springs. ASSOCIATED SPRING CORP. 19 Aug., 1967, No. 38301/67. Heading B3D. The ends of helical springs are ground as they are passed between opposed grinding wheels 24, 26 by a rotatable carrier 8, the springs being fed directly to holes 10 in the carrier from a coiler A by a tube 6. The carrier is rotated above a fixed supporting plate 32 for the springs by a flexible drive 18 operated by a chain 22 and cam shaft 20 on the coiler. The discharge end of the tube 6 is held by a resilient arm 40 over one of the circular rows of holes 10. The rows may be of various sizes and the grinding wheels may be adjusted to suit different sizes of springs. The carrier is rotated continuously while the end of the tube 6 is caused to oscillate by the intermittent engagement and disengagement of a pin 46 controlled by a cam surface 62 on the carrier. In a second embodiment, Fig. 3 (not shown), the carrier is intermittently stopped to receive a spring from a fixed tube by means of a pin (100) operated by a piston-and-cylinder arrangement controlled by a cam (114) and valve (118), the drive for the carrier being constituted by a pair of nylon clutch plates (76, 78) which slip each time the carrier is stopped by the pin. In a third embodiment, Fig. 4 (not shown), two or more tubes (6, 6a) are provided for feeding springs to more than one row of holes at a time, the springs produced by the coiler being fed into the tubes by a reciprocating or oscillating device, Figs. 5 and 6 (not shown). The springs may also be set by compressing them to their solid condition before the grinding operation by means of a solenoid-operated plunger (182), Fig. 7 (not shown), while being transported by the carrier, the plunger being mounted on an arm (160) which is connected to the resilient arm (40) by a link (162) fcr following the oscillating movements between switches (186, 190) as the arm (40) rides on cam surface (62); alternatively, the springs may be compressed after grinding, Fig. 8 (not shown) or both before and after grinding Fig. 9 (not shown).
