Patent GB-1188433-A (GB)
Title: Data Processing Apparatus
Inventor: SPRUTH WILHELM
IPC: G06F9/22
Filed: 1968-09-11
Abstract: 1,188,433. Error checking in data processors. INTERNATIONAL BUSINESS MACHINES CORP. 11 Sept., 1968 [27 Sept., 1967], No. 43161/68. Heading G4A. In data processing apparatus, a check number is generated for a series of groups of N data bits (e.g. micro-programme instructions or parts thereof) being transferred from one location (e.g. card reader) to another (e.g. core memory), by using N counting devices each counting the 0-to-1 and 1-to-0 changes in a respective bit position when the counting device is conditioned (see below), and the check number is compared with a stored check number to determine whether the transfer is complete or correct. The counting is modulo-2, each counting device being an EXCL-OR fed by the counting device input and the 1 output of a flip-flop, the EXCL-OR feeding the flip-flop, which provides the counting device output. In one embodiment, all the counting devices are conditioned for every group of bits, and three stored check numbers are provided any one of which or all in turn (manual or automatic selection) can be compared with the generated check number e.g. to determine if the micro-programme entered into the machine is applicable to this machine. In a modification, the counting devices are enabled in turn by a decoded clock-driven binary counter so that each counting device responds to a respective 1/Nth of the bit-groups. A further modification has 3 such binary counters forming a single binary counter and controlling respective check number generators each as above, each bit-group going to the three generators in common. In this case the 3 generated check numbers are compared with respective thirds of a stored check number.

Filed: 1972-09-29
Abstract: 1400863 Dual circuit safety valve ROBERT BOSCH GmbH 29 Sept 1972 [2 Oct 1971] 44954/72 Heading F2F A dual-circuit braking system has a twocircuit safety valve 4, disposed between a pressure generator and respective pressure reservoirs 18, 18<SP>1</SP> for each circuit, having a non-return valve for each circuit which allows pressure medium to flow into each circuit, when the circuits are free from leaks, and a respective piston 6, 6<SP>1</SP> providing a seat 10, 101 for each valve and having a surface acted upon by the reservoir pressure of one circuit and an opposed annular surface acted upon by the reservoir pressure of the other circuit so that if a leak occurs in one of the circuits, the respective non- return valve is actuated by its piston to isolate the circuit from the generator. When both circuits 19, 19<SP>1</SP> are intact, pressure medium from the generator in the form of a pump 1 flow past ball valve members 9, 9<SP>1</SP> biased by springs 11, 11<SP>1</SP>, to respective brakes 22, 22<SP>1</SP> via a further valve 20; pressure is also maintained in the reservoirs 18, 18<SP>1</SP>. The pump 1 operates when pressure in at least one of the reservoirs 18, 18<SP>1</SP> falls below a predetermined minimum, and is controlled by an electromotor having pressure switches actuated by reservoir pressure or is continuously driven and the supply is controlled by a pressure switch valve. If a leak occurs, in one circuit, say 19, then the pressure on a face F of the corresponding piston 6 will drop, and the pressure on the opposing face R from the other reservoir 18<SP>1</SP> plus the pump pressure on a face f thereof will overcome the force of a spring 13 to move the piston 6 leftwardly. The travel of the ball valve member 9 is limited by a rod 14 so that eventually the non-return valve will close to isolate the defective circuit 19 but allow continuous functioning of the other circuit 19<SP>1</SP>.

Abstract: 1399463 Fibre reinforced resin; laminates BAKER PERKINS CHEMICAL MACHINERY Ltd 28 Dec 1972 [28 Sept 1971] 45184/71 Headings B5A and B5N [Also in Division D1] Fibre reinforced moulding material is prepared by impregnating continuous or chopped fibres with liquid, passing the impregnated material through consolidating rollers 10 and adding liquid resin to one side by means of a transfer roll 11 carrying resin from a feeder roll 13 dipping into a resin bath 14 to one of the consolidating rolls 10. In Fig. 1 parallel rovings 1 pass through a hood 2 on to a roll 3 which applies styrene wetting agent from a trough 4. The rovings are chopped by cutting rolls 6, 7 and are blown down a hopper 8 on to a pervious rotating cylinder 37. The top half of the cylinder is evacuated to form the fibres into a layer which falls off the unevacuated lower portion of the cylinder and into the nip of rolls 10 where styrene resin is applied to both faces. Alternatively styrene-wetted rovings 27 are supplied unchopped to the rolls 10 by a feed unit 25, 26 or, Fig. 2 (not shown), uncut rovings (33) are impregnated and guided through eyelets which oscillate laterally to form a diamond mesh of fibres which is consolidated by rolls 10. The consolidated sheet 15 falls from the rolls 10 on to a polythene cover sheet 18 carried by an endless conveyer belt 16. A second consolidated sheet is deposited on the first by a second unit 24 and an upper polythene cover sheet 19 is applied. The laminate is compacted in a compressing conveyer 21 before passing through an oven 22 for curing to the B stage. The sheet 18 may be replaced by boards of plywood, asbestos, chipboard or wood fibre for the manufacture of panels. In Fig. 3 a roll of the resulting sheet moulding compound is slit and the cover sheets 54 peeled off on to rolls 55. A share 52 may turn one strip over on to another before the material is carried over a weighing cylinder 45 and is chopped into charges 48 by a guillotine 46, 47. The charges 48 are picked up and separated by a conveyer belt running at a higher speed and a transfer device 50 synchronized with the belt feeds them to a multihead press 51. The laminate from the belt 16, Fig. 1, or the consolidated sheet from the rolls 10 (Fig. 2, not shown) may alternatively be fed to an extruder 29, 30 (or 35, 36). As the material is extruded it is sheathed for storage by one or two polythene sheets which are welded longitudinally to form a tube. When required the covering sheath is slit and the moulding material cut into charges as before.

A thermo-couple limb comprises a number of intimately bonded layers of dissimilar materials which have optimum thermo-electric properties at different temperatures and it is made by arranging the layers in the order of temperatures at which they exhibit their optimum properties and then compacting them so as to form a unitary sintered body. The thermoelectric efficiency of a number of materials is discussed with reference to Figs. 1 and 2 (not shown) and a thermo-couple embodying the invention is depicted in Fig. 4. The P- type limb is constructed by placing, in a graphite mould, powdered layers of bismuth antimony telluride, zinc antimonide (200 mesh), germanium bismuth telluride (200), germanium telluride (200) and the cold compressing at 500 p.s.i. The limb is subsequently hot pressed at 500 C. and 5000 p.s.i. for 45 minutes and then removed from the mould. Between some or all of the layers, "barrier " layers may be formed to prevent undesirable reactions between adjacent layers, these " barriers " consisting, for example, of powders of cobalt, chromium, molybdenum, silicon, tantalum or zirconium. Alternatively nickel or iron layers may be used to ensure good bonding between layers. The N-type limb is constructed in the same way from lead telluride and bismuth tellurium selenide. Both limbs are then soldered to a highly thermally conductive metal strip 14 and electrical contacts 24, 26 of copper or iron are added. The latter contacts may be formed during the moulding process using metallic powders. Reference has been directed by the Comptroller to Specification 907,901.
