Abstract: 1,239,203. Valves. DUNLOP CO. Ltd. 25 Sept., 1968 [29 Sept., 1967], No. 44410/67. Headings F2F and F2V. A valve for use in anti-skid devices comprising two movable valve members 15, 27 shifts from a first condition allowing normal brake application to a second condition in which a source of pneumatic pressure is employed to reduce the braking in such a way that dynamic pressure of the exhaust does not prevent rapid shifting of the valve. The source of pneumatic pressure is connected to an inlet chamber 12 and is prevented from flowing to the outlet chamber 13 by a first valve member 15 urged against seat 9 by a spring 19. Internally of member 15 is an exhaust passage which is in communication with the atmosphere via a hole 37. The flow to the exhaust from outlet chamber 13 is governed by the second valve member 27. The position of valve members 15, 27 as shown in the Figure allows normal braking to proceed, i.e. the outlet 13 to the brake releasing device is open to exhaust and the inlet 12 is closed. A rotary inertia skid sensor acts on valve member 27 when skidding is imminent so that the exhaust is first closed by part 31 of valve 27 and then the inlet 12 is allowed to communicate with the outlet 13. When the skid sensing means ceases to operate, the inlet 12 is first closed, followed by an opening of the outlet chamber 13 to exhaust. The dynamic pressure which would otherwise have tended to open the valve 15 on seat 9 is balanced by the pressure acting on a diaphragm 32 tending to close the valve 15.

Abstract: 1,265,707. Piezo-electric generators. CONSTRUCTIONS ELECTRIQUES R.V. 14 Oct., 1969 [29 May, 1969], No. 50320/69. Heading H2A.  In an igniter comprising an actuating sleeve 21 slidable on a tubular support 3 for a piezoelectric element 2, movement of the sleeve in the direction A against a spring 24 subsequently releases a locking device between a hammer 15 and the support and allows the spring 24 to drive the hammer into engagement with the element 2. In the inoperative position shown, a ball 18 located in an aperture 25 in the support is held in engagement with a groove 19 in the hammer by a bush 20 slidable between sleeve 21 and the support whereby the hammer is locked to the support. As the sleeve moves in the direction A it carries with it the bush 20 which eventually allows the ball 18 to move out of groove 19 to release the hammer. Sleeve 21 is returned by the spring 24 leaving behind the bush 20 until a further spring 30 returns the hammer to a position in which the ball can reenter groove 19 into which it is then urged by a chamfered surface 20b on the bush. Such movement of the ball then permits the bush to be returned to the locking position by a spring 27. The element 2 is retained in the support and prestressed by a cup spring 10 which also forms a connection between one end of the element and the support. The other end of the element is connected to a U-shaped electrode 5a which extends through an extension 4a of an insulating sleeve 4 and forms a spark gap 5 with a nut 5b on the end of the support.

Abstract: 1290064 Automatic exchange systems SIEMENS AG 17 Dec 1970 [19 Dec 1969] 59846/70 Heading H4K . A switching matrix comprising a relay in series with a diode at each cross-point is provided with a first voltage supply for normally reverse biasing the diodes and a second voltage supply of opposite polarity and lower absolute value than the first for forward biasing a single diode and thus bringing up a unique relay when it is applied to a relevant row and column. The first potential is applied to each column and row supply wire over the break-side of a changeover contact, e.g. xm, yn while the second potential is applied over the make side of these contacts. The breakside contact is shunted by a resistor, e.g. Rxm, Ryn to ensure continuity of the current paths during the selection operation. Since the reverse bias potential ŒU directly applied to a row or column wire not having its change-over contact operated is always greater than the forward bias potential Œu applied to a row or column wire having its change-over contact operated, then, even if a diode such as G43 has broken down so as to draw operating current for its associated relay R43, no other cross-point relays will be inadvertently operated. Thus the potential on X4 is -U irrespective of whether G43 is faulty or not so that if say Y2 is marked with -u during a selection operation, diode G42 will still be reverse biased and so R42 will not operate. Similar considerations apply to the row wires. The system is a development of that in Specification 1,015,451. The switch is monitored for faults so that a faulty cross-point can be marked permanently busy in a path finder's memory map. The arrangement also confines the fault to a single switch of a stage having common supply wires for each of the switches therein, an example being provided by Specification 1,171,075.

Abstract: 1295453 Semi-conductor matrices ENERGY CONVERSION DEVICES Inc 28 Oct 1969 [4 Nov 1968] 52759/69 Heading H1K [Also in Division G4] A memory matrix comprises crossing sets of X and Y conductors deposited on an insulating substrate. A bi-stable memory switch comprising deposited semi-conductor material which changes from a high to a low resistance state above a threshold voltage is located at or adjacent each crossover point and is connected between the crossing conductors via a device for isolating it from the effects of switching pulses applied across either of the memory switches. In the embodiments the isolating devices are threshold devices and they and the memory device are both of the general type described in U.S.A. Specification 3,271,591. The devices may as shown in Fig. 8, be formed respectively on associated X and Y conductors by deposition of appropriate material in a 10 Á diameter pore 48 in an insulating layer and be joined by a conductive track 50, the conductors being mutually insulated at the physical intersection by deposits 44. Alternatively memory material is deposited on the Y conductor, threshold material deposited to contact it via a pore in an insulating layer and the associated X conductor deposited directly over the threshold material. Normally the threshold device has an " off " resistance up to 1000 times that of the memory device. A binary 1 can be stored by applying between selected X and Y conductors a voltage to switch on one device and hence also the other. On removal of the setting voltage the threshold device reverts but the memory device stays on. To reset it a voltage sufficient to drive the threshold device " on " is applied via a circuit providing a current sufficient to reset the memory device. Readout is effected non- destructively by a voltage sufficient to switch on the threshold device but insufficient to switch on the memory device through a circuit providing insufficient current to switch it off, the condition of the memory being sensed by the voltage across a series resistor.

Abstract: 1305192 Sorting objects photo-electrically UNITED KINGDOM ATOMIC ENERGY AUTHORITY 30 April 1970 [19 May 1969] 25529/69 Heading G1A [Also in Division G2] Translucent bodies are sorted from opaque bodies by passing the bodies 5 in sequence through a radiation beam 2' having one dimension small in relation to the body size and detecting radiation emitted from those parts of the body which are not directly illuminated. If the body is opaque, radiation will be scattered from the body only at the point of incidence Fig. 1a (not shown), and thus will not be detected, but if the body is translucent some penetration and internal reflection will occur Fig. 1b (not shown), and radiation will leave the body from an area around the irradiated one to impinge upon the detector. This method may be used in the extraction of low-grade uranium to differentiate between translucent fragments of quartzite containing 30 Á gm uraninite and opaque fragments containing 400 Á gm uraninite. The light source may be a laser, tungsten iodide lamp, quartz iodine lamp or a xenon arc, and a narrow beam is produced using a slit 9. An occulting bar 8' is provided in the direct light path between the irradiated part of the moving fragment 5 and a photo-multiplier or silicon photo-diode 6'. If the fragments are sufficiently large a plurality of illuminated areas may be provided. In another embodiment - Fig. 4- light is directed towards a moving sample along a fibre optic light guide 11. Any directly reflected light from an opaque fragment is  received back on the surface 13 of this bundle, but light scattered back from a translucent fragment is received on a surface 14 of a bundle 12 and is transmitted to a detector 16. In other embodiments Figs. 6, 13 (not shown) the transmitting surface 13 comprises in X-section a plurality of parallel strips (13') alternating with parallel receiving strips (14'). Alternatively Fig. 7 (not shown) the transmitting surface may be in the form of a cross (13") bounded by receiving surfaces (14"). The physical sorting is effected by allowing the fragments to fall in sequence past a detecting arrangement of the kind previously described. The detector output is fed to a threshold device which, after a suitable time delay, operates a mechanism for rejecting unwanted fragments in to a different hopper from the one that receives opaque fragments Fig. 14 (not shown).
