Title: Improvements in or relating to photographic film carriers for stereoscopic viewing devices
IPC: C10B5/02
Filed: 1937-04-17
Abstract: 493,881. Stereoscopic apparatus. KODAK, Ltd. April 17, 1937, No. 11032. Convention date, April 29, 1936. [Class 97 (i)] A removable picture carrier for stereoscopic viewing devices comprises spaced holders connected together by means which permits them to vary their angular relation to each other. The viewing device, Fig. 1, has eyepieces 13 and 14 in tubes 11 and 12 pivoted at 15. The interocular distance is varied by rotating the sleeve 22 threaded on to arms 20 and 21. The carrier inserted in the guides 32 is shown in Figs. 2-4 ; Fig. 4 being a section at 4-4 of Fig. 2. The two separate holders 35, 36 are formed from a single sheet of metal, the flexibility of the central portion 37 being sufficient to permit the interocular adjustment of the viewing device. Each picture, 52, on a piece of kinema film, is held between sheets of glass 60, 61 over a viewing aperture 45, and located by lugs 50 bent up from the edges of the aperture to engage the film perforations. The glass plates 60, 61 are held by flanges 44. In a modification, the lugs 50 are carried by a separate sheet of metal.

Filed: 1971-04-23
Abstract: 1350985 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 April 1971 [28 April 1970] 11066/71 Heading H4F A colour television receiver includes an integrated chrominance amplifier circuit 45 arranged to provide at the output of an amplifier 51 a signal which, during the colour bursts, is independent of the amplitude of the received bursts and the settings of contrast adjusting circuit 29 and saturation adjusting circuit 99. During occurrence of a burst a pulse is produced by generator 35 which is fed to combination circuit 87 and then to transistor 83 to cut this transistor off so that the whole of the current flowing through transistor 95 flows through transistor 79  and resistor 81. A pulse from generator 35 during a burst also gates on gate 61, and an AGC signal from rectifier 69 is passed to transistor 97 to maintain the burst output constant. One or more of the inputs at terminals 89, 91, 93 to combination circuit 87 may be applied in the opposite sense to the base of transistor 79 rather than to transistor 83. Transistors 95, 97 may be omitted with AGC operating on a stage preceding or following circuit 45.
Patent GB-253310-A (GB)
Title: Improvements in or relating to projectile fuses
IPC: F42C15/26
Filed: 1925-04-28
Abstract: 253,310. White, A. E., (Bethlehem Steel Co.). April 28, 1925. Projectile fuzes. - Relates to fuzes adapted to be cocked on discharge and to fire the fuze on impact after retardation has ceased. According to the invention, the fuze comprises means for cocking the hammer on discharge, means for holding the hammer cocked during flight, and means energized by the impact to release the striker upon cessation of retardation. As shown in Fig. 1, the hammer 36 is held in an inner sleeve O by bolts B locked by an outer sleeve S. The sleeves 0, S and the hammer are held back, and an " anticipator holder " 30 is pressed forward, by a. coiled spring 32. On discharge, a plunger 42 sets back and compresses the hammer spring 40, and segments 45 open out into a recess 46 in the sleeve 0, thereby holding the plunger back and the hammer cocked. The anticipator holder also sets back. there being a small gap 29 between it and the sleeve S: but it is returned forward again by the spring 32 when acceleration is over. On impact, the sleeves S, 0 and the hammer 36 and the plunger 42 all move forward together, except that the sleeve S is arrested before the rest, after which the bolts B remain locked by the wall of the fuze body 13. When acceleration is over, the spring 32 returns sleeve 0 and hammer 36 back; and towards the end of this movement, a ring 47 which has expanded from the sleeve 0 bears on the sleeve S and drives this back also. At the end of this return movement, the bolts B are wedged out into the wider chamber 24 of the fuze body and the striker is driven against a primer 18 which fires a detonator 20, Fig. 5, communicating the explosion to a " booster " charge 15. The detonator 20 is carried by a safety shutter 19. If quick action is desired instead of the delayed action described above, the nose plug 50 is removed from the contour cap 11 and a rod is inserted through this hole and into a socket 31 in the anticipator holder 30. On impact, this rod with the anticipator holder is driven in and holds the sleeve S back, while the hammer and sleeve 0 are still free to move forward ; the bolts B are therefore released immediately. In a modification, Fig. 9, the sleeve S and the anticipator holder of a base fuze are replaced by two sleeves 60, 61. The bolts B<1> can pass through slots 62 in the sleeve 60 but are normally locked by the end of the sleeve 60. On impact, both sleeves move forward, but a ball 70 moves radially out of a recess 71 between them and thereby displaces them longitudinally relatively one to the other; and the bolts B<1> are released by the sleeve 60 but remain locked by the sleeve 61 until acceleration is over, when the sleeves are returned back and the bolts B<1> are released by the sleeve 61 before they can be locked again by the sleeve 60.

Title: Improvements in or relating to wind-screen wipers
IPC: B60S1/44
Filed: 1943-07-09
Abstract: 564,789. Windscreen-wipers. FRANGHIA, S. B. July 9, 1943, No. 11126. [Class 138 (i)] A windscreen-wiper of the kind in which the wiper blade 8 is given a rotary motion about an axis at right angles to the plane of the blade, is constructed with an arm 5 for carrying the blade 8 which is joined to a tube 11 extending through the windscreen or its frame, the tube 11 being rotatable so as to bring the arm from operative to parked position, or vice versa, by cam or eccentric mechanism, e.g. by cams 37, 38, which operate to move the tube 11 from one position to the other, in conjunction with locking devices which hold the arm and tube 11 in adjusted position. The tube 11 is provided with a segmental flange 30, Fig. 2, and the cams 37, 38 operate plungers 39, 40 which engage shoulders 31, 32 on the member 30 to rotate the tube 11 so as to move the arm 5 into and out of operative position. The cams are operated by a handle 36 on a rod 34, and in the operative or inoperative positions the arm 5 is locked in position since the axis of the plunger passes through the peak of the cam and the axis of the cam-shaft. The cam-shaft 34 is fitted with two ratchets 41, 42 engaged by pawls 44, 45, Fig. 3 (not shown), which operate in turn to control the direction in which the shaft 34 can be rotated, and the operating-pawl can be released by a cam 48 operated by a sleeve 46 with handle 47 when the movement into parked or active position has been completed. The cam 48 is integral with a further cam recess which controls the current to the motor which drives the bevel gear 20 from which is derived the means for rotating the pad 8. The drive can thus only take place when the arm 5 is in operative position and is transmitted through bevel gears 21, 24, 25, 27, 28. The connection between the pad 8 and its driving-shaft is a splined one, so that a spring 8a can press the pad 8 into contact with the screen 10, and rollers 8c on the blade engage ramps on the body work to guide the blade into the " parked " position.

Patent GB-812511-A (GB)
Title: Improvements in or relating to the production of solid sodium nitrite
IPC: C01B21/50
Filed: 1957-04-05
Abstract: <PICT:0812511/III/1> Granular sodium nitrite in a non-caking form is produced by adjusting the moisture content of granular sodium nitrite to 2 to 9 per cent by weight and forcing the moisture-adjusted salt through a die having a multiplicity of circular openings, and slicing the strands emerging into segments having a length not more than three times their cross-sectional diameter.  The pellets are finally dried to a moisture content of less than 1.5 per cent by weight.  The sodium nitrite may be prepared by absorbing nitrogen oxide in an alkaline solution and crystallizing the solution obtained to produce a granular solid salt.  The moisture content of such salt is preferably adjusted to 2.5 to 5 per cent by weight and such salt may then be fed at 30 DEG  C. to an extrusion apparatus, a part view of which is shown in the Figure.  The granular salt is fed through an aperture 8 into a rotary die cage 1 having circular apertures 2.  A pair of rollers 4 just touching the inner surface of the die plate are mounted for idle rotation and the strands of nitrite extruded are cut off by a slicing blade 6.  The pellets are removed from an orifice 7 and are dried preferably to a moisture content below 0.5 per cent.
