Title: Improvements in and relating to the manufacture of organic materials
IPC: C08J5/02
Filed: 1928-10-06
Abstract: 323,755. Dunlop Rubber Co., Ltd., Murphy, E. A., and Niven, A. Oct. 6. 1928. Indiarubber, colouring.-One or more coloured aqueous dispersions of an organic substance such as rubber are floated on to the surface of a bath of a dispersion of a different colour, with or without gentle mixing, and a former is dipped into the bath to form an article having a jazz pattern or the surface next to the former; or the former is immersed in the dispersion, a differently coloured surface layer is floated on, and the former is withdrawn, forming a variegated outer surface. The pattern may be varied by irregular movements of the former. Suitable dispersions are natural or artificial dispersions of rubber, gutta, balata, &c. which may be preserved, concentrated, compounded with, for example, factice, waste, reclaim, synthetic rubber or resins, vulcanizing ingredients, dyes. leather, cork, metal dust, fibres, &c. A typical mix consists of latex containing 73 parts of rubber, 2.5 parts of sulphur, 0.4 parts of zinc diethyl-dicarbamate. 3 parts of zinc oxide, 5 parts of whiting, 6.1 parts of china clay, 3 parts of iron oxide or other colour, 7 parts of transformer oil. The setting of the deposits may be by drying, or by dehydrating as described in Specification 303,544. A gloss is obtained by using a polished former, and drying, and preferably partly vulcanizing, before stripping. A wrinkled surface may be obtained as described in Specification 324,988. The invention is applicable to the forming or coating of articles.

Title: Improvements in or relating to fastener driving tool
IPC: B25C1/12
Filed: 1956-09-20
Abstract: 799,561. Cartridge actuated tools for firing bolts &c. RAMSET FASTENER, Inc. Sept. 20, 1956 [Dec. 6, 1955], No. 28763/56. Class 119 A stud driving tool has an interchangeable barrel 22 which, when axially displaced by the pressure' of the work-surface on its nozzle, permits the operation of the firing mechanism, but the barrel 22 cannot be displaced unless it has been properly assembled into a carrier 100 which moves with it. A rear housing 30 carries a pistol grip 20, a trigger 46 with firing mechanism 40 and 42, and a breech lock 37. The rear housing 30 is hinged on lugs 58 and a pin 61 to a front housing 54 to which it is detachably connected by spaced lugs 63 which engage with lugs 51b in the front housing 54. The barrel 22 is reduced in diameter externally where it screws into the carrier 100 and has a tapered surface 114 which makes a tight fit with an internal taper 115 on the carrier 100. The carrier 100 and barrel 22 can slide longitudinally through a sleeve 51 screwed to the housing 54 to cock the firing mechanism and are limited in this direction by a stop pin 53 operating in a slot 101. A safety shield assembly is slidably held on the barrel by a locknut 75 and is urged forward by a spring 26 housed in a guard tube 70. The rear end of the spring 26 abuts on a bevelled lock-release ring 82 which co-operates in turn with an inclined face on a pair of C-shaped gripper members 80. The members 80 are biassed inwards by a split-ring spring 81 so that they tend to seat themselves in a groove 109 in the collar 100 and so prevent its backward movement. Compression of the spring 26 when the shield engages a work surfaces lifts the members 80 out of the groove 109 so that the barrel assembly is freed to move back if nothing else prevents it. However, on the external surface of the reduced rear end of the barrel there is a circumferential groove 105 which is alignable with a radial hole 106 in the carrier 100. A ball 107 is held in the hole 106 by rims 108 and as its diameter exceeds the length of the hole it projects from it at one end or the other. If the barrel 22 is not screwed fully home so that the ball 107 is in the groove 105 the ball projects outwards and fouls the rear corner of the sleeve 51, thus preventing the mechanism from being cocked and fired. More than one ball may be used, if desired.
Patent GB-1394929-A (GB)
Title: Hydraulic direction-control valve
IPC: F15B13/01
Filed: 1973-06-18
Abstract: 1394929 Marine steering systems CAPILANO ENG CO Ltd 18 June 1973 28841/73 Heading B7V [Also in Division F2] A valve controlling the rudder operating ram 1 in a marine steering system comprises a valve body 11 having inlets 16, 17 for pressure liquid from opposite sides respectively of a reversible pump and outlets 25, 26 leading to opposite sides respectively of the ram piston 2, non- return valves 27, 28 being provided adjacent the respective outlets. A bore communicating with inlets 16, 17 and drain 18 contains spools 40, 41 biased apart by spring 44 and having spigots 42, 43 extending towards each other and spigots 15 extending towards the plugged ends of the bore. Thus when liquid is pumped, e.g. to inlet 16 spool 40 is urged rightwards to open port 21 but close return port 23 so that liquid flows through passage 19, non-return valve 27 and outlet 25 to the left side of ram piston 2. Simultaneously the pressure in passage 19 acts via the clearance between restriction 45 and spigot 30 of a piston 29 to urge the latter rightwards until spigot 31 unseats valve 28 and permits liquid from the right side of ram piston 2 to be returned to drain 18 via passage 20 and port 24. When pump pressure is removed from inlet 16 spring 44 returns spool 40 leftwards closing port 21 but communicating ports 23 and 24 so that the pressures equalize on opposite sides of spool 29, the latter thus ceasing to unseat valve 28. The restriction 45 prevents hunting of the rudder when moved from a hard-over position. The system may include, as shown, at least one other identical control valve in parallel with the first for controlling the rudder from another position of the ship. The return spring 44 prevents a condition wherein the control liquid from one valve flows to drain via the other valve rather than to the ram 1. The pump may be of swash plate type directly connected to a hand operated steering wheel.

Title: Improvements in or relating to optical projection apparatus
IPC: G03B1/42
Filed: 1929-09-23
Abstract: 333,089. Leitz, E. [Firm of]. May 3, 1929, [Convention date]. Optical-projection apparatus.- In optical-projection apparatus wherein a film is held by transparent discs when stationary, the feeding means and means for moving one of the discs to free the film are arranged so that a loop is formed in the film after each feed movement; delay occasioned by the subsequent taking-up of the loop permits the disc to be moved from the film before the beginning of the next feed movement. As shomn, film reels 12, 13 are carried on a plate 10 secured to a ring 9 fitted over the condenser housing 4. A sleeve 18 rigidly secured to the plate 10 carries the projection lens mount 19 and houses a ring 22 carrying a transparent disc 23 pressed by a spring 24 against a transparent disc 25 fixed on the plate 10. An arm 27 secured to the ring 22 carries a pin 30 engaging a non- radial slot 31 in a plate 32 normally secured to a feed sprocket 14. Rotation of the sprocket by hand in a clockwise direction, as shown, first moves the ring 22 and disc 25 while taking up the loop 34, and there feeds the film upwards. When the plate 32 has been rotated so that the pin 30 again enters the slot, and the hand is removed, the spring 24 acts to press the disc 23 on to the film and to rotate the sprocket backwards to form the loop 34. The plate 32 is secured to the sprocket spindle, and the sprocket is capable of being rotated relatively to its spindle, without movement of the plate 32, when film centering &c. is to be effected.

Title: Improvements in steering apparatus for ships
IPC: G05D1/02
Filed: 1923-11-20
Abstract: 221,998. Winter, O. E., and Steinmetz, K. Nov. 20, 1923. Steering-gear; steering and manoeuvring automatically.-A steering-gear for automatically stabilizing the new course upon a change of course includes control apparatus which, after a steering movement of the rudder, returns the rudder beyond the middle position through an angle proportionate to the initial angular movement of the helm before the rudder is finally restored to the mid-position. In an electric steering gear where the motor 2 is controlled by starboard and port switches 6, 7, closing the contacts results in a movement of the rudder, and on subsequent release the automatic control operates to govern the return of the rudder. The automatic control comprises switch levers 18, 19 mounted on a shaft 20 and having insulated con. tacts 21 - - 25 connected to the various circuits. The switch lever 19 is positively operated by levers or other connections from the rudder stock. The switch lever 18 is free on the shaft 20 and is connected to the lever 19 by adjustable links 31, 32. In the. mid-position of the rudders, the levers all lie along the same line and are locked by catch 38 engaging the end 39 of the lever 32; also the contacts 21 and 23 are connected, the contacts 22 and 24 are connected, and the contact 25 is held free by the pin 47. The contacts 50, 51 in the circuits of the relays 10, 11 are connected by the piece 52 on the link 31. When the switch 7 is closed the member 16 closes the circuit 53 of the motor 2 and the rudder is moved over, .at the same time the levers 19 and 18 are moved proportionately, whereby the contact 25 engages contact 21 and the return circuit 55 of the motor is prepared. On the switch 7 being again opened, the circuit 53 is broken and circuit 55 completed, whereupon the rudder swings back and with it the lever 19, which slides the pin 33 but leaves the lever 18 free. When the levers 18, 19 are in line the rudder has overreached its mid-position but the contacts are now operative to reverse the motion and restore the rudder to normal. The arms 18, 19 are locked by the catch 43, 44, and therefore return with the rudder to the fore, and aft position. The linkages 31, 32 can be set so as to obtain any predetermined proportion of overswing of the rudder. In automatic steering gears the switches 6, 7 can be replaced by selenium cells under the control of the compass needle. Alternatively, the compass shaft may carry two. cams which operate tumblers in the circuits. The levers 18, 19 may be concentrically mounted on the rudder shaft and connected thereto by gearing which includes ratchets which are suitably tripped to provide for the relative motions of the levers such as is given by the leakages described above.

Filed: 1973-06-20
Abstract: 1422381 Image pick-up tubes HITACHI Ltd and NIPPON HOSO KYOKAI 20 June 1973 [3 July 1972] 29323/73 Headings H1D and H1K A photoconductive target of an image pick-up tube e.g. a vidicon, includes, in sequence, a light-transmitting substrate, e.g. glass, an N-type conductive layer, and a P- type conductive layer forming a rectifying contact therewith, the P-type layer including at least Se and Te and having a composition which varies through its thickness such that the average content of Se is not less than 50 atomic per cent, the content of Te at the two surfaces of the layer is not more than 10 atomic per cent, and the maximum Te content of 10 to 40% lies in a plane which is to the N-type layer side of the mid-plane of the P-type layer. The P-type layer may also contain one or more of As, Sb, P, Bi, Ge, and Si, to reduce the speed of crystallization, and may have its free surface coated with a 1000 Angstrom thick evaporated  layer of Sb 2 S 3 , As 2 Se 3 , or As 2 S 2 , to reduce electron beam landing disturbance arising from secondary emission. The controlled variation of composition may be produced either by simultaneously evaporating the separate components from different evaporation boats and adjusting the different rates of evaporation, or by evaporating the different components in cyclic succession to build up a multiple sandwich of thin layers. The N-type layer either be formed wholly of the oxide of Sn, In, or Ti, or-to further assist in the reduction in the speed of crystallization of the P-type layer-may be of CdS, CdSe, ZnS, or ZnSe, in which case a higher conductivity layer, to act as an electrode is also required. This high conductivity layer may either be an oxide layer of Sn, In, or Ti, or a transparent metal layer evaporated on to the substrate. The target provides increased sensitivity to the red portion of the spectrum.
