Patent GB-1264883-A (GB)
IPC: H01R25/14
Filed: 1969-05-27
Abstract: 1,264,883. Two part couplings. NOVUM A.G. 27 May, 1969 [28 May, 1968; 18 April, 1969], No. 26783/69. Heading H2E. An electrical distribution system, wherein the supply conductors extend within a rail having one open side, has connector units each comprising a support member formed such that on insertion through the open side and engagement with the rail in a transverse direction, a plurality of contact members mechanically coupled to the support member are caused to make contact with the conductors. As shown in Fig. 2, upon deformation of the sides 10, 11 of the metal support member 9 towards each other, contact elements 35-38 are pivoted inwardly on terminal members 43-46, by push buttons 61-64 on plastics shell halves 28, 29. The connector unit is then inserted into the rail, correct orientation being ensured by flanges (24-26) in the rail and portions 67 on the end wall of the insulating member 34 (Fig. 1, not shown). Upon releasing the support member, flanges 12, 13 engage counter-flanges (16, 17) and the contacts 35-38 are urged into contact with the conductors (3-6) by springs e.g. 50. The rail is U- shaped in section having a metallic shell (8) carrying a plastics U-shaped portion (7) which carries the conductors (3-6). The plastics portion may be extruded around the conductors. In a second embodiment (Fig. 3, not shown), the support member (113) is retained in a compressed state by a locking pawl (115) which has arms (116, 117) passing through holes (118, 119) in the support member and is retained by spring (114), the compression of the support member is transmitted to the contacts (102-105), three of which have plastics pimples to insulate them from the metal support member, the fourth (105) being the earth contact. Upon insertion of the unit into the rail (101), the locking pawl is forced back through the holes (118, 119) by the engaging flanges (124, 125), thereby releasing the support member from compression and allowing the contacts to engage the conductors, and the flanges 122, 123 to engage the rail.

Abstract: 1290550 Gravity - separation apparatus EASTMAN KODAK CO 13 Nov 1969 [15 Nov 1968] 55642/69 Heading B1D [Also in Division Gl] Clear liquid 12 is automatically withdrawn from a vessel 10 where it is present between scum (or foam) 18 and a sludge 14 of precipitated floc, by means of a suction pipe 20 the mouth 26 of which is associated with a sensor 28 of scum and of floc 16 suspended in clear liquid, this sensor also controlling a valve 24 in the pipe 20 and a servo drive 22 which lowers the pipe vertically. Mounted in tube 20 above sensor 28, there is a sensor 46 for clear liquid, e.g. a pair of contacts which are electrically short-circuited when in an electrically conductive liquid. With the mouth 26 positioned above vessel 10, the power supply 48 is energized by closing its switch, thereby applying a signal to drive servo 22 to move pipe 20 downwards. As the mouth 26 drops into the scum 18, the sensor 28 produces an output signal which makes the NOT circuit 38 produce no output signal thereby allowing valve 24 to remain closed. Valve 24 opens when sensor 28 first enters clear liquid 12; and suction commences. The servo 22 continuous to lower pipe 20 until sensor 46 dips into the clear liquid 12, whereupon sensor 46 energizes self-holding relay 42 so that switch 40 is actuated and circuit 38 now operates servo 22. If sensor 28 does not detect floc, valve 24 remains open and, as the clear liquid is drawn off through pipe 20, the servo 22 lowers the mouth towards the sludge 14. Eventually, when all the floc has settled as sludge, the clear liquid 12 will be completely drawn off, leaving within vessel 10 only the scum 18 and the sludge 14. Sensor 28 may detect the presence of scum or suspended floc by reflection of light from a lamp, periodically excited by an electrical pulsing device, onto a ganged photocells (see Division G1). Alternatively, the sensor may be a gallium arsenide radiation emitter and excitation circuit of the "Emitting Diode" type.

Abstract: 1295032 Fastener attaching machine TRW Inc 2 Jan 1970 [7 Jan 1969] 192/70 Heading A3H A fastener attaching machine 10 has a fastener attaching station at 18, and a mechanism for feeding swatch material to a worktable, for cutting off a predetermined length of swatch material, and for tilting the worktable, as described in the paragraphs below. A fastener component and a work product are attached to the pre-cut swatch material during the period of deflection of the worktable. The prime mover for the swatch feed mechanism is drive rod 50, powered from the main drive linkage for the fastener attaching station via links 26, 40, 42 &c. The movement of drive rod 50 causes a drive crank to rotate, which in turn drives both the swatch feed mechanism and the knife actuating means via a mechanical sequencing device. The drive for the feed mechanism is taken via drive rod 118, crank 128, and gears 130 and 150, to a knurled roller which draws swatch material from a roll situated below the work table, and delivers it through a guide plate 186 to the surface of the worktable. The moveable knife member 212 is driven through drive rod 94 and a series of links 190, 196, 200, and 204. At the end of its movement the knife actuator crank 204 bears down on a stop member 222, whereupon the table deflects about pivot 158 against the tension of the springs 216. In the timed sequence of operation, it is at the lowest .point of the deflection of the table that the fastener is attached through a work product and the pre-cut swatch material.

Abstract: 1345064 Filter press BERDICHEVSKY ZAVOD KHIMICHESKOGO MASHINOSTROENIA PROGRESS 29 Oct 1971 50322/71 Heading B1D Filter press plates 1 are clamped together against fixed upper plate 3 by a pair of hinged arms 5 whose central hinges are moved together by hydraulic ram 12, 13 to straighten the arms and thereby raise lower plate 4, and the ram is locked by a second ram 16 inserting wedge 17 into rod aperture 14 when the plates are fully clamped. Clamping is initiated by signal Pyl moving valve 18 rightwards, which delivers fluid to the rod space of cylinder 12, wedge 17 being held down by the constant pressure in the rod space of ram 16. When the plates 1 are fully clamped, cam 22 moves valve 21 which moves valve 19 leftwards, thereby supplying fluid to valve 20 which is itself moved rightwards by the rising pressure in the rod space of cylinder 12. Valve 20 then delivers the fluid from valve 19 to the piston space of ram 16 and raises wedge 17 into aperture 14. Ram 16 and wedge 17 are carried by extension 15 of cylinder 12 and move therewith when ram 12, 13 is operated. To lower the plates 1, signal Py2 moves valve 19 rightwards, and the piston space of ram 16 is thereby connected to return. The force available to lower wedge 17 is greater than that which raises it, the latter depending on the differences between upper and lower areas of the piston. Valve 18 is restored to the position shown by its spring and ram 12, 13 expanded. The press may be as described in Specification 1,080,461

Abstract: 1354287 Determination of organic nitro and nitroso compounds; photo-electric measurements NATIONAL RESEARCH DEVELOPMENT CORP 17 May 1971 [21 May 1970] 24596/70 Headings G1A and G1B Organic nitro or nitroso compounds are detected and/or estimated by subjecting vapours from them to a controlled thermal degrading to produce nitrogen dioxide and passing them into or through a test reagent for detecting nitrogen dioxide. The method is particularly suitable for the detection of nitroglycerine but may also be used for the detection of ethylene glycol dinitrate, di-ethyleneglycol dinitrate and nitroisobutyltrinitrate. A suitable reagent is sulphanilamide with N-(1 naphthyl)- ethylene diamine which couple on reaction with nitrogen dioxide to form a red dye. The reagent is preferably absorbed on a substrate of alumina, silica gel or paper. Nitrogen oxide and/or nitrogen dioxide present in the atmosphere may be removed, prior to the thermal degradation step, by scrubbing, preferably with fine chromic acid and powdered sodium hydroxide; or alternatively a comparison test may be carried out simultaneously on a sample of the atmosphere known not to contain organic nitro or nitroso compounds. Tests may be carried out using the semi-portable apparatus shown in Fig. 1, in which the vapours are drawn by an electric pump (not shown) through stainless-steel tube 2, glass scrubbing towers 5, 9, glass tube 13 containing an electrically heated platinum wire 14 for effecting the thermal degradation, tube 19 containing the reagent 20, a moisture trap 23 and a flow-meter 24. The tube 19 may be replaced by an absorbtion cell, Fig. 3, (not shown), filled with a solution of the reagent and fitted with a lamp and a photo-cell. A double cell, Fig. 4b, may be used when a comparison test is to be made. This is made from transparent plastics and each cell chamber 36 has a gas inlet 37, a gas outlet 38, a light source 44 and a photo-cell 39. A filter 41 may be secured by an end cap 40. The outputs of the photo-cells may be measured differentially and the resulting signal may control an alarm.
