In a first embodiment the tulip contact is movable, the arrangement being such that when the movable contact stud 10 is moved in the direction F, during opening of the circuit breaker, the movable tulip contact 27 initially follows it under the influence of a spring and an arc is struck between this tulip contact 27 and the fixed contact 9, the tulip contact following the movable contact stud until it is stopped by ring 32 while the movable contact stud continues alone through the nozzle 6 drawing a further are struck between itself and the tulip contact through the nozzle, the arcs heating the gas in the first chamber 4 to increase its pressure so that it blasts through the nozzle to extinguish the arcs. The ring 32 directs the gas blast axially through the nozzle, and the rails 8, 21 allow the arc between the fixed contact and the tulip contact to rotate, being slitted spirally or in the form of windings. In a further embodiment the tulip contact is fixed adjacent the ring at the nozzle and has itself a nozzle through which the moving contact stud passes, Figs. 5 and 6 not shown. A three chamber arrangement is disclosed wherein the first chamber lies between two others from which it is separated by respective nozzles through which respective movable contact studs can pass.

Abstract: 1420130 Making magnetic heads INTERNATIONAL BUSINESS MACHINES CORP 11 Sept 1973 [11 Oct 1972] 42651/73 Heading G5R In a method of making magnetic heads to obtain a desired throat height an electrically conductive film 2, 3, 4 is deposited on a substrate 1 to form a plurality of heads 2, 3 each having a transducing element conductive film portion with an initial excess of material on one side, and there being a bridge conductive film portion 4 connecting the transducing element portions of adjacent heads, the bridge being located on the side with the initial excess of material, a respective pair of leads 5, 6, 7, 8 for each head are arranged so that the leads are connected by the transducing element portion of the respective head, the resistance of the bridge portion is then monitored through two leads connected to different heads whilst removing material at a first rate from the bridge portion and substrate until the monitored resistance indicates circuit discontinuity between the transducing element portions of the heads initially connected by the bridge portion, and then the resistance of at least one transducing element portion is monitored through the leads eonnected thereto whilst removing material at a second rate from the one side of the transducing element portions and substrate until the resistance or resistances being monitored has or have reached a predetermined value indicative of the desired throat height. The method may be applied to multiturn heads or single turn heads, e.g. as disclosed in Specifications 1,343,860 and 1,372,474, and of inductive type having a copper film 2, 3 single turn with a nickel-iron alloy magnetic yoke 9, 9<SP>1</SP>, or of magnetoresistive type having a single magnetoresistive turn on a nickel-iron substrate. The material removal may be by grinding, lopping or weaving or by electrochemical techniques. Bridges 4 between adjacent conductor elements 2, 3 of a multitrack head may be rough ground whilst monitoring the resistance of each bridge in turn, e.g. via leads 5, 8 and scanning switchgear, Fig. 4 (not shown), until a desired number of bridges break, indicated by open circuits. The heads are then fine ground whilst monitoring the resistance of each element 2, 3 in turn. The head assembly may be adjusted in any of two or three axes during grinding to provide uniform material removal and compensation for fabrication tolerances, uneven removal being indicated by different monitored resistances. The grinding operations may be computer controlled.

Abstract: 1,192,329. Image intensifiers. ZENITH RADIO CORP. 9 Sept., 1968 [21 Sept., 1967], No. 42833/68. Heading H1D. An image intensifier comprises a generally cylindrical glass envelope 10 sealed at one end to a glass cap 14 and at the other end to an optically flat glass disc 31 forming the output window. In manufacture the shoulder 9 is coated with chromium which is oxidized to form a resistive coating 47; this coating and other areas which are not to be coated with conductive material are masked whilst chromium or aluminium is evaporated to form the electrode rings 25, 26 and 28 as well as a coating extending from the shoulder 9 to the anode sub-assembly 30. This sub-assembly, Fig. 2, comprises the anode 40 into which is fitted a fluorescent screen 35 clamped between metal rings 36 and 37, and which is adapted to spring over a clamping ring 33 formed on the disc 31 and surrounding the viewing window 33. After the anode assembly is installed the anode lead 45 is inserted through tube 46 and attached. The cathode assembly 24 is supported on three tines 61 extending through tubulations 50-52 from a fixture 60 and is cooled by nitrogen flowing through the fixture 60 and the tines 61 to exhaust ports 66 whilst the cap 14 is sealed to the envelope part 10. The fixture 60 is then advanced to move the cathode assembly 24 up the tube to a position level with apertures 12 through which pins are passed to engage bushings 22 on the assembly to provide support and electrical connection. After the fixture 60 is withdrawn, one of the tubulations 50-52 is sealed off, the photocathode layer is deposited in known manner, after which the exhaust tubulation is sealed off and the other tubulation is connected to an ion pump which maintains the vacuum. If the tube is for receiving X-rays the cathode assembly 24 may comprise an aluminium dish on which is deposited an X-ray sensitive phosphor such as silver-activated zinc sulphide in a silicone resin; a barrier layer of aluminium oxide is superimposed on the phosphor, and a photo-emissive layer of antimony-caesium completes the assembly.

Abstract: 1,187,279. Knitting-machines. STRICKMASCHINENBAU KARL-MARX-STADT, VEB. 22 Sept., 1967, No. 43169/67. Heading D1C. [Also in Division G3] Pattern butts of bits of a multi-section Jacquard knitting machine are broken off by a device responsive to the scanning of a pattern master or extract by at least one electric scanning device, pulses from scanners of the scanning device being fed to at least one electric storage device, having as many individual stores as scanners, the braking-off device being operated by the storage device. As shown a black and white pattern extract 1a( 1b) is illuminated from the rear by a fluorescent tube 15 and the pattern elements are scanned by photoresistors 16 each of which is connected to a storage element, comprising a thyratron 17. The photoresistor is connected with a resistor 21 as a potential divider in the grid circuit of a thyratron across a rheostat 20 comon to all the thyratron grid circuits. An indicating glow lamp 25 is associated with each thyratron. The thyratrons are interrogated by a rotary switch 35, driven by a motor 27, to actuate a relay 37 energising a solenoid 30, selectively in dependence on a black or white pattern element, through a change-over switch W. The switch 35 is driven in common with a control roller, not shown, actuating a switch 39. The solenoid 30 operates a butt-breaking out device, a solenoid 31 determining the stepwise displacement of the device to the appropriate butt and a solenoid 32 triggering the return of the device to the starting position. The pattern extract is advanced by a solenoid 33. The contacts 43, 44, 34, controlling the sequential operation of 31, 32, 33 are actuated by the control roller. The butt breaking-off device is movable parallel to a row of pattern butts and is adjustable to the butt to be broken off. The switch W is used with double scanning of the pattern and enables the response colour to be changed. For a pattern composed of two or more motifs the bits are provided with additional pattern butts. Transparent photocopies of knitting may be used as pattern masters or extracts.
