Title: Improvements in or relating to Heat Storage Systems
IPC: C23F15/00
Filed: 1968-09-19
Abstract: 1,189,778. Preventing corrosion in heatstorage systems. COMSTOCK & WESCOTT Inc. Sept. 19, 1968 [Sept. 26, 1967], No.44594/68. Heading C7E. [Also in Division F4] Corrosion of the metal of a sealed container housing a material that reacts with said metal to generate hydrogen is inhibited by producing hydrogen at the external surface of the container at a temperature sufficient to effect diffusion of hydrogen through the container wall. A particular application of this process is in heat-storage systems of the type comprising a closed iron vessel containing NaOH, wherein the iron is protected from corrosion by the generation at its surface of nascent hydrogen by reaction of atmospheric water vapour with the iron, which reaction may be assisted by the provision on the iron of a coating such as silica gel, alumina, or a zeolite, which absorbs water vapour.

Title: Apparatus for Remotely Operating Pressure Operated Elements.
IPC: F16K31/528
Filed: 1967-10-02
Abstract: 1,159,745. Valves. ROCKWELL MFG. CO 2 Oct., 1967 [19 Oct., 1966], No. 44819/67. Heading F2V. [Also in Division F1] The supply of fluid to remotely positioned hydraulic or pneumatic actuators for operating, e.g. valves (not shown), is controlled by a plurality of control valves 3, 4 situated near the actuators and each having an individual actuating plunger 43 or 44 selectively depressed by an operating unit 2 itself operable by the same fluid used to operate the actuators and controlled from a remote position. The unit 2 is in the form of a stem 71 selectively rotatable to one of a number of indexed positions, wherein axial displacement thereof causes set screws 51 carried by a plate 52 on the end of the stem to depress the control valve 3 or 4 selected for operation. Rotation of the stem 71 is achieved by pressurization from a remote point of an annular chamber 67 in which is disposed the end of an annular piston 59 surrounding the stem 71. The annular piston 51 is movable axially but is prevented from rotating by radial screws 81 slidable in slots 60 in a housing 58. The inner ends of the screws 81 engage in a zigzagged cam track 100 cut in the periphery of the stem 71 so that axial movement of the piston 59 up to a shoulder 64 causes rotation of the stem to a new index position but balls 73 located in a recess 62 in the housing prevent axial displacement. If the pressure supplied to the chamber 67 is increased the balls 73 are forced radially inwards by an incline 63 of the recess 62 until they clear the recess 62 and the stem is allowed to be displaced with a snap action against a spring 74, whereby the selected valve(s) is/are operated.

As shown, the camera contains a supply spool 71 of image-transfer material comprising a pressure-rupturable container 75 for processing fluid, a light-sensitive area 73 and a trap 76 for used processing fluid. The material is pulled out of the spool and exposed at station 77 via lens 93 and mirror 92 to give a latent laterally reversed image and is then moved to processing station 78. Lever 89 is moved counter clockwise so that backing member 86 contacts the exposed material as shown and nip 87 seals trap 76 from the exposed areas. Knob 82 is then pulled so that roller 80 moves far enough to rupture container 75 and free processing fluid between the exposed emulsion and the image-receiving layer. Backing member 86 is then moved away after soaking the material with fluid and knob 82 pulled so that roller 80 presses the image-receiving layer and the lightsensitive emulsion into contact and forces the unused fluid into trap 76. The material is then removed from the camera via aperture 79 and cut by knife 94, the emulsion being stripped from the positive image on the image-receiving layer. The camera preferably uses the materials of Specification 1,102,883 and the processes of Specification 1, 102, 881.

Title: Device for hydraulic control of a centered multiposition directional control valve
IPC: E02F9/22
Filed: 1975-11-07
Abstract: 1494400 Valves NORDHYDRAULIC AB 7 Nov 1975 [7 Nov 1974] 46173/75 Heading F2V [Also in Division G3] The pilot valve of a directional control valve (13) includes a spool 47 which is movable by a handle 18 through a spring 55 to connect a pressure supply conduit 45 with a proportional pressure outlet 50 through radial passages 64 and axial passage 63 to give a pressure at outlet 50 proportional to the movement of the spool and thus the handle. During this movement a spring-loaded detent ball 58 moves in a groove 59 of an actuating plunger 52. However, the ball can be caused to ride over the land 60 into groove 57 so as to hold the spool 47 in a position in which an outlet 53 is connected directly with the pressure supply conduit via the groove 62. The outlets 50, 53 are connected respectively to the chamber (40) of a single-acting actuating cylinder and a chamber (37) of a double-acting actuating cylinder the other chamber (36) of which is connected to an outlet 50 of a further spool valve of the pilot valve. The piston of the double-acting cylinder is directly connected to the spool of the directional control valve whereas it is connected by lost-motion with the piston of the single-acting cylinder. Pressure supplied to the chambers of the actuating cylinders cause the directional control valve spool to assume forward, reverse and float positions, the spool normally being held in an open-centre central position by a centring spring device. The pilot valve includes a further two spools which are used to actuate a further directional control valve. All of the pilot valve spools are normally biased to the position shown in which both the outlets 50, 53 are connected to drain conduit 46 via the passages in the spool, the connection being cut off by spool lands 65, 61 on downward movement of the spool. The detent ball may be released by an electromagnetically-operated valve 86, 87, which on movement to the left connects passages 77, 76 to connect supply pressure to the right of piston 82 to move it to the left to release the pressure on the ball 58.

Title: Improvements in machines for the thermal treatment of textile yarns
IPC: B65H51/16
Filed: 1963-11-26
Abstract: In heat-treating and cooling stages of false-twist crimping, a yarn passes through a U-shaped guide conduit the inlet and outlet ends of which are adjacent the distance there-between being independent of the overall length of the conduit.  In a multiple station machine the two branches (7a, 7b) of each conduit are horizontal and located one above the other; the conduits open alternately at opposite sides of the machine; the entry branches (7a) are heated by passage through a common, electrically heated and heat insulated, metallic block (8); the other branches (7b) are cooled by passage through the atmosphere, or a vessel in which water circulates, and circulation of an air stream therethrough. In or near the bend (7c) between branches, one or more suction pipes (58) or apertures enable waste vapours produced in heated branches to be withdrawn into common suction collecting conduits (59).  Yarn is "threaded-up" by sucking or blowing it through the conduit by temporarily connecting one end to a flexible pipe (60) leading to a travelling vacuum pump (49) or a compressor: another suction member (50) attached to the pump (49) enables withdrawal of an initial uncrimped or unsatisfactory crimped yarn portion prior to connection of correctly crimped yarn to a receiving reel.

Abstract: 1,106,126. Bushing insulators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 11 Dec., 1964 [26 Nov., 1963], No. 46677/63. Heading H2C. The shape of an insulating bushing is determined by, firstly, using an electrolytic tank analogue or other technique to plot a first isodynamic surface between electrodes simulating the conductor 9 and a conducting annulus 7 to be embedded in the bushing; secondly, modifying the tank so as to simulate the effect of arranging a piece of the insulating material to be used between the parts 7 and 9, the piece having the shape of the first isodynamic surface, and plotting a second isodynamic surface lying within the first, and thirdly, plotting the final surface so as to be parallel at each point to the second surface and so as to produce a surface stress of desired magnitude lower than that corresponding to the second surface. The method may be used even when the ambient medium is to be different on one side of the annulus from that on the other side, in which case the bushing will be asymmetrical. The bushing is then moulded of silicon-filled epoxy resin.
