IPC: H01J43/24
Filed: 1969-03-26
Abstract: 1,258,307. Electron multipliers; electrode materials. MURATA MFG CO. Ltd. 26 March, 1969 [29 March, 1968 (2)], No. 15866/69. Heading H1D. An electron multiplying device is constituted by a moulded body 20 of a barium titanate system semi-conductor ceramic, which material is itself secondary electron-emissive, the body having at least one hole 23 therethrough provided with conductive material 21, 22 at each end to form two electrodes. The barium titanate system semi-conductor ceramic is produced by sintering in an inert or reductive atmosphere a composition comprising barium titanate which may contain a rare earth element or an element having a valency of not less than five, e.g. Ta or W. At its temperature of operation the ceramic material should have a positive or zero resistancetemperature characteristic, and an example is given having the following composition- Ba 0À828 Sr 0À170 Ce 0À002 Ti 0À830 Sn 0À170 O 3 . The moulded body may be in the form of a single elongated tube of, for example, circular, triangular, hexagonal or other polygonal cross-sectional shape. A number of such bodies may be stacked together and any gap 24 between them also acts as an electron multiplying channel, and using octagonal shaped bodies with every second side arc-shaped, Fig. 5 (not shown), this channel may be the same size as the hole. A bundle of such bodies may also be twisted together to increase the secondary-emissive path length for a composite body of given width. Alternatively a number of holes may be bored in a large single body of the ceramics material. Suitable electrode materials are conductive silver or carbon paint, indium-gallium alloy, chemically plated nickel, tin or aluminium film or baked silver. The electron multiplying device may be used as one element in an image intensifier tube.

Abstract: 1290130 Electro-chemical analysis F HOFFMANN-LA ROCHE & CO A G 31 Aug 1971 [1 Oct 1970] 40636/71 Heading G1N A method of detecting presence or measuring flow, uses a marking substance introduced into the sample through a wall or membrane permeable to the substance and detected by an electrode external to another permeable wall section. Applications mentioned are measuring flow of blood and testing for leaks. As shown Fig. 2 water flowing in a tube 16 is "marked" by hydrogen admitted through a valve 23 to a hydrogenpermeable membrane 18 e.g. of P.T.F.E., and the arrival of the hydrogen downstream is detected by electrodes 13, 20 abutting a permeable partition 21. The resulting signal from the electrodes is amplified at 24 and applied to a paper-feed type recorder 25 which is started simultaneously with the opening of the hydrogen valve. For determining blood circulation the patient inhales one breath of 10% hydrogen in nitrogen gas. The hydrogen is absorbed in the lungs and detected when it reaches an electrode applied to a suitable body part e.g. the corner of the eye Fig.3 (not shown).

Abstract: 1304219 Apparatus for and a method of securing fastener portions to carpets, mats or the like STANDARD-TRIUMPH MOTOR CO Ltd 25 April 1970 19971/70 Heading B4C A tool for use in securing a fastener portion e.g. of a press-stud or snap-action fastener and a pronged locating ring to a carpet, mat or the like comprises an annular recess of concave section in an end face of the tool, and a stop means for correctly positioning a fastener portion so that, when a fastener portion is positioned with prongs of the locating ring extending through the carpet or the like and through apertures in the fastener portion, movement of the tool towards the ring will cause the ends of the prongs to be bent over against the fastener portion. The stop means is such as to limit, in use, the movement of the fastener portion towards the locating ring. As illustrated the fastener portion 17 is a female portion and has apertures 22 through which prongs 19 of the ring 18 extend and the stop means is a boss 15. Alternatively the tool may have a detachable head 30 which carries an adjustable boss 15 screw threadedly received in the head 30 and locked in a selected position by a lock nut 28. Handle 12 is provided with a hole for receiving a bar and the head may be provided with flats engageable by spanner to facilitate separation of the head and handle. One method of securing a female fastener portion 17 and a pronged locating ring 18 to a carpet 20 using a board 23 of a size and shape corresponding to the carpet and provided with preformed recesses 24 comprises placing a pronged ring in a recess with its prongs upwards, laying the carpet to completely cover the board with the pile downwards, applying pressure to the carpet to force the prongs through the carpet, positioning a fastener portion over the ring with the prongs passing through the apertures in the portion, positioning the tool 11 as illustrated and applying a downward force. The board may be of metal e.g. steel or wood and in the latter case each recess is provided with a metal insert 25 which may be magnetic.

Abstract: 1313140 Valves DEFENCE SECRETARY OF STATE FOR 1 July 1970 [3 July 1969] 33546/69 Heading F2V [Also in Division F1] In apparatus which comprises a reservoir 1 having a vent 7, delivering coolant 47 through a tube 13 and flexible line 15 to a device 17, the vent 7 is closed by an electro-mechanically actuated valve which comprises a solenoid 23 and a spring-biased lever 27. When a sensing element 19 in the device 17 is not being cooled an electrical bridge 21 sends a signal through an amplifier 25 to actuate the solenoid 23, thereby attracting an armature 31 on the lever 27 and thus closing the vent 7 by a seal 35. Heat entering the reservoir 1 causes the pressure above the coolant to increase thus forcing coolant through the tube 13 and line 15 to the device 17. On subsequent cooling of the element 19 the bridge 21 is re-balanced and the solenoid 23 is deenergized thus opening the vent 7. The pressure then decreases, the flow of coolant stops and eventually the element 19 becomes warmer with consequential closing of the vent 7. This cycle continues until the reservoir 1 is exhausted. Should the pressure in the reservoir 1 become too great the valve acts as a relief valve and the seal 35 is blown from the vent 7, the pressure overcoming the attractive force of the solenoid 23.

The dispenser may feed articles to a micro-wave oven. The stacks may be formed by plates sliding on the smaller flanges of asymmetrical I-beams 71, the plates carrying prongs which pass through holes in plates 22 as they pass the level of the conveyor. The conveyors are formed of a single loop of wire, horizontal runs thereof forming the conveyor surfaces. The racks may be displaceable by a wire drive Fig.7, (not shown). The dispenser may be refrigerated, and have a glass front. The dispensing may be coin-controlled, and selection made by push buttons. The activating circuits of the dispenser may be in the same circuit as those of the micro-wave oven, so that dispensing cannot take place unless the oven is on. Micro-switches may be provided at each end of the movement of the rack, to prevent overrun, and, at the bottom, to light a "column empty" sign. Micro-switches are also provided to stop descent of the rack when an article is deposited on the conveyor. Time delays and photo-electric cells may be provided to ensure that articles do not follow too closely. A solenoid-actuated door may also be provided between the dispenser and the oven.

The jaw 1 is slidable on rollers 4 in the vertically movable block 5 acted on by the force applying mechanism and the jaw 2 is similarly mounted on the frame 6, the block 5 and frame 6 being movable towards the other workpiece. The wall 13 forms two chambers 17, 18 in the cylinder 14 and the area between the wall and piston in each chamber communicates with the slide valve 9 spring urged to the left against a screw 24 carried in the projection 8 and coupled to pressure supply and return lines 21, 20. The area between the wall and piston 11 is also connected to a spring urged piston 25 in an eccentric operated supply system 19 and the area between the wall and piston 12 is connected to a spring urged piston 26 of the sytem 12. The arrangement is such that with the eccentric of system 19 rotating and the parts in the position shown, fluid from the piston 25 moves the piston 11 and thus the jaws and workpiece to the left, the control valve moving to the left also until the chamber 17 is connected with the return line 20. The chamber 18 is connected via the valve to the pressure line 21 and when the piston 26 supplies fluid to the chamber 18 the jaws and workpiece are moved to the right. Thus during the general movement of the jaws and workpiece towards the other workpiece during flashing a vibration is superimposed. After flashing the workpieces are up set.
