Abstract: 1,068,461. Conveyers. SHAW, TREW & SMITH Ltd., and D. G. SHAW. Jan. 10, 1964 [Oct. 11, 1962], No. 38496/62. Heading B7L. Control mechanism for a mine car creeper 4 is tripped by the approach of a car 3 to cause the creeper to be driven to effect a backshunt of the car. As a car 3 approaches a buffer 15 a dummy axle 30 or other part contacts a trip member 29 which forces a cam plate 25 rearwards so that the follower pin 21 is moved from a neutral position shown in Fig. 1 to cause the control valve of an hydraulic motor 16 to drive the creeper 4 forwards so that its pusher 2 produces a backshunt of the car 3. As the trolley 1 of the creeper approaches its forwardmost position during backshunting, the pusher member 2 contacts a cross-piece 34 of rods 31 connected to a rear cam-plate 26 which is thus moved forwards with the cam-plate 25 moving the pin 21 through the neutral position to a position to cause the control valve to effect reverse drive of the trolley 1. As the trolley then approaches its rear position it contacts a lug 36 connected only to the cam-plate 26 which is thus moved rearwards to position the pin 21 in its initial neutral position ready for the approach of another mine car 3.

Title: Temperature responsive actuators
Inventor: KUZE YOSHIKAZU
IPC: G05D23/02
Filed: 1967-08-24
Abstract: 1,203,074. Valves. Y. KUZE. 24 Aug., 1967 [27 Aug., 1966; 5 Nov., 1966; 14 Feb., 1967; 29 March, 1967], No. 39040/67. Heading F2V. [Also in Division G1] A temperature responsive actuator for a valve 13 comprises a heat-conductive chamber 10 in which is disposed a guide 18 for a push-rod 23, the remaining space in the chamber 10 being filled with a thermally expansible material 22, e.g. wax, to push the rod 23 outwardly from the chamber 10 and open the valve 13 against the action of a spring 12, a plug 20 of rubber or other resilient material being interposed between the expansible material 22 and the rod 23 to seal against the guide 18 and prevent leakage of the material 22. The guide 18 has an end portion which is held in place by a flange 17 integral with the walls of the chamber 10. An anti-chafing disc 25 of plastics material is interposed between the plug 20 and the end of the push-rod 23, the end of the plug 20 contacting the material 22 preferably having a convex shape, and the plug being shaped to have an enlarged diameter at this end, so that it has to be compressed radially to force it into the guide 18. This assists the sealing action of the plug 20. A ring seal 27 held in place by a disc 28 provides a seal between the push-rod 23 and guide 18, the push-rod 23 being secured, adjustably as shown, or by riveting to a bridge member 6 on a housing 1 in which is formed a seat 5 for the valve 13. After repeated use and when the durability of the plug 20 has come to an end, the valve 13 is arranged to remain open since at this stage the ageing of the plug will increase the friction between the plug 20 and the guide 18 to such an extent that the friction will overcome the effect of the spring 12 tending to close the valve which will thus remain open.

Title: Improvements in or relating to the creasing of carton blanks
IPC: B23P15/40
Filed: 1959-11-19
Abstract: 909,331. Creasing. SQUIRE, H. F. Nov. 1, 1960 [Nov. 19, 1959], No. 39296/59. Class 100 (2). A creasing matrix strip consists of a base strip 1 having two longitudinally extending and mutually spaced ridges 3 thereon, the base strip consisting of or including a metal and the ridges consisting of or including a thermoplastic artificial resin or fibrous material e.g. fibreglass bonded by an epoxy or melamine resin. The strip 1, which may be of mild steel or aluminium, has parallel lines of holes 2 punched therein, which holes are surrounded by upstanding, tooth-like portions of the metal. The ridges 3 are strips of P.V.C., cellulose acetate or nylon and are keyed to the metal strip by the tooth-like portions. The matrix strip may be assembled as shown in Fig. 5. The metal strip 1 is fed between rollers 5, 6 which respectively carry radially projecting pins and co-operating recesses for punching the holes 2 in the strip. The punched strip passes round a heated drum 7 and then, together with strips 8 of artificial resin, between the roller 7 and a further roller 9. In this way the strips 8 are pressed on to the tooth-like portions and form the ridges 3. In a modification the base strip 1 is of metal gauze and is embedded in a plastic strip in which the ridges 3 are formed. Adhesive is applied to the underside of the matrix strip for securing it to the platen of a platen press or to the impression cylinder of a cylinder press. The matrix strips may be temporarily attached to the creasing rules by means of pieces of rubber temporarily mounted on the ridges 3 in order to facilitate mounting of the matrix strips on their platen in register with the creasing rules. If the matrix strips are mounted on an impression cylinder the ridges 3 may be partially slit at intervals along their length in planes perpendicular to their longitudinal axes, in order that they may more easily follow the curvature of the cylinder. If the ridges 3 are of fibrous material they may be secured to the strip 1 by adhesive as well as by the tooth-like portions. Reference has been directed by the Comptroller to Specification 807,251.

Abstract: 1482472 Semi-conductor devices THOMSON-CSF 13 Sept 1974 [14 Sept 1973] 40120/74 Heading H1K A memory comprises an integrated array of PNPN switch elements the dimensions &c. of which (in particular those of one of the inner regions) are such that each element switches from a non-conducting to a conducting state as a result of punch-through rather than of breakdown as in conventional PNPN elements. The bias and control voltages are consequently very low ( ~2-3 volts and ~ 1-2 volts respectively), the power consumption is low and the switching time is fast (#10 nanoseconds). Fig. 3 shows one such array of diodes formed on a P+ substrate 10 contacted by a common anode 80. In an N-type epitaxial layer 20 are formed, by diffusion or implantation, P + isolation walls 40, P-type regions 60 and N + -type cathode regions 70. The conductivity and thickness of the unconverted part of layer 20 are sufficiently small to permit punch-through in response to a relatively small pulse across an element. The elements may alternatively be thyristors, a gate electrode being provided on an N + surface zone in the layer 20. Fig. 9 shows a modification in which the substrate is of P- conductivity and serves only to support and isolate the elements of the array. Each element has a separate anode 120 connected to a P- anode region in the N-type layer 20. As shown a gate electrode is provided on a P- zone 100 of P- type inner region 60 to provide a thyristor, but this feature may be omitted, providing an array of PNPN diodes with independent anodes and cathodes.

Abstract: 1438968 Regulating air-fuel ratio ROBERT BOSCH GmbH 24 Aug 1973 [25 Aug 1972] 40160/73 Heading F1B A fuel metering system for mixture compression spark ignition I.C. engines comprises an air-flow measuring element 2 and a throttle valve 3 in series in an inlet manifold 1, the element 3 being adapted to be displaced proportionately to the air-flow against a restoring force and to move a valve 7 in a fuel supply line for metering fuel in proportion to the air-flow, the proportion being variable by controlling a valve 17 in a by-pass 16 around the measuring element, the valve 17 being controlled by an exhaust gas measuring probe 26. Probe 26 produces an electrical signal representative of the amount of oxygen in the exhaust gas, the signal being amplified at 26 and fed to a solenoid 22 which controls the position of a spring biased armature 20, which normally closes the end of the upstream section of the pipe 16. The downstream end of pipe 16 is closed by a disc 18 having a calibrated aperture, the position of this end of the pipe being such that as the throttle valve opens the pipe is subject to an increasing extent to the depression downstream of the throttle valve. In a first modification, Fig. 3 the valve member 35 is mounted on a diaphragm 36, one side of which is subject to the intake manifold depression through a pipe 40 which leads to a valve 41, containing a valve member 42 the position of which is determined by the current in a solenoid coil 44, which is connected to the oxygen probe. According to the position of the member 42, pipe 40 is connected to a greater or lesser degree to the inlet manifold or an atmospheric vent 47. In a  second modification, Fig. 4 (not shown) the solenoid is mounted on the diaphragm housing and controls the position of a leaf spring, the free end of which is situated in a narrow gap between the opposed open ends of two pipes, one leading to the inlet manifold and the other to atmosphere. The position of the leaf spring thus determines the degree of depression to which the diaphragm is subjected.
