Abstract: 1,233,012. Vacuum furnaces. C. I. HAYES Inc. 26 Oct., 1968, No. 50916/68. Heading F4B. [Also in Division H5] A vacuum furnace 10 comprises a housing 12, a heating zone 42 located in said housing, means 77 for supporting a work load that is to be heat treated in said heating zone, means 112 for moving said supporting means into and out of said heating zone, means 192 communicating with the interior of said housing for quenching said work load after said heat treatment, and means 96 for transferring said work load to said quenching means after withdrawal of said work load from said heating zone and without removal of said work load from exposure to the vacuum within said housing. In operation, the work to be heat treated is placed in a basket 86 which is inserted into the housing 12 and placed in an interlocking position on a platform 78 of the support member 77. A control device 145 is then operated to move the elongated rod 112 in a longitudinal direction toward the heating chamber 42 moving the member 77 from a first track section 88 to a second track section 90 with the heating chamber 42. After the articles located in the basket 86 have been heat treated for a predetermined period of time, the control device 145 automatically operates to retract the support member 77 on which the basket 86 is located toward the position shown in full lines is Fig. 1. As soon as the support member 77 reaches the position that locates it between the rings 92 and 94 within the ring cage assembly 96, the track section 88 together with the ring cage assembly is moved through an arcuate path upon operation of a further control device 184. The control device rotates the assembly 96 through an angle of approximately 180 degrees which movement locates the basket 86 in position for dumping of the heat treated articles therefrom into the quench shoot 194, the articles falling through baffles 200 into a quench liquid located in a tank 204. Vaporization of the quench liquid, usually oil, is substantially prevented by means of the cooling coils 202 that surround the shoot 194 and the upper portion of the tank 204.

Abstract: 1,253,174. Aerials. COMPAGNIE GENERALE D'ELECTRICITE. 20 July, 1970 [23 July, 1969], No. 35008/70. Heading H4A. An aerial comprises reflectors 18, 20 which are located respectively at the top and at the foot of a mast 2. The reflectors are linked by ties 22, 24, 26 and are so mounted that displacements of one are transmitted to the other through said ties. As described, the mast 2 is stayed, and has a triangular support frame 16 at its top which carries the reflector 18. The reflector 20 is rotatable about a fixed centre, and is supported from the ground on frames 30, 32, 34. Both reflectors are plane, and are normally inclined at 45 degrees to the horizontal. A parabolic reflector 28 is mounted on the mast 2 opposite the reflector 20, and has a feed horn at its focus. Plane waves from the reflector 28 are directed upwards by the reflector 20 to the reflector 18, which re-directs them horizontally. If the reflector 18 is tilted because of wind, a corresponding movement is communicated to the reflector 20, so that the reflectors remain parallel, and the waves continue to be directed horizontally. The reflectors 18, 20 may be elliptically shaped, and the reflector 18 may be larger than the reflector 20 and be made slightly concave, to correct wave-front deformation.

Abstract: 1,256,726. Fire extinguisher discharge valve. FIREMASTER EXTINGUISHER Ltd. 4 June, 1970 [27 June, 1969], No. 32555/69. Heading A5A. A pressurised fire extinguisher container 10 is closed by a discharge valve comprising plunger 17 with striking tip 19 adjacent closure diaphragm 12 on the container mouth, an outlet duct comprising outlet bore 14 and passage 15 leading to discharge nozzle 16, compression spring 21 urging plunger 17 away from diaphragm 12, and co-operating first and second seals on the plunger and duct to close the duct to the passage of fluid when and only when the plunger is pressed into the diaphragm. Plunger 17 is urged by spring 21 to a first position governed by circlip 22 in an annular groove on stem 18, which abuts radial face 23 of bore 14. Collar 24 located on a spigot formation on cap 11 so that it surrounds diaphragm 12 is formed with internal radial lip 25 which retains "O" ring 26 within 24 abutting the end face of the spigot, the upper face of 24 engaging with radial face 27 of body 13 so as to put 26 under axial compression. The internal diameter of 26 is slightly less than that of stem 18. In use, depression of knob 20 forces tip 19 through ring 26 and diaphragm 12. After driving inwards to this second position the knob is released and is urged back by spring 21 so that extinguishant may be expelled through nozzle 16. Flow is only halted when the knob is again depressed to the second position, where tip 19 is through the "O" ring and the end cylindrical portion of plunger 17 between tip 19 and circlip 23 is in sealing engagement with the "O" ring to close the passage. Circlip 23 assists sealing by passing axially through lip 25 to abut the outer radial face of ring 26. Thus the extinguisher cannot be mistakenly stored in partly empty condition.

Abstract: 1,256,865. Carbon fibres. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 16 Dec., 1968 [22 Dec., 1967], No. 58382/67. Heading C1A.  Oxidized fibre, which may be subsequently carbonized or graphitized, is produced by heating organic fibre at an oxidizing temperature in an oxidizing atmosphere, the process comprising winding a length of the fibre round a support formed by a plurality of spaced guides, the ends of the fibre being fixed so that when the fibre is heated it is restrained by the guides from shrinking, and moving the fibre with respect to the guides during heating so that every part of the fibre that contacts a guide surface moves for a greater time out of contact with the guide surface than in contact therewith. One form of support is shown in Fig. 1 which illustrates a furnace 10 having a gas inlet 11 and outlet 12, together with a circling fan 13 driven by motor 14. The oxidizing gas, e.g. air drawn at a controlled rate through the inlet and discharged via the outlet 12 together with volatiles emitted from the fibre. Located within the furnace is a rectangular support 16 comprising a base member 17, a top member 18 and two side members 19. A pair of rollers 20, 21 are journalled in the side members at the top and bottom of the frame. A reduction gear-box 22 is mounted on the frame and is driven by a shaft 23 which extends through the lid of the furnace. Drive is transmitted to the rollers by means of a shaft 24 extending from the gear-box and carrying a sprocket 25 which is connected to a sprocket 26 on spindle 27 of the roller 20. The other end of the spindle also carries a sprocket 29 which is connected to sprocket 30 on the spindle of roller 21. The fibre is kept in position on the frame by two grooved guide rollers 32, or the rollers themselves may be grooved. A continuous tow of fibre, e.g. 10,000 filaments of polyacrylonitrile is wound on to the support and the two ends are knotted on to the next adjacent length of fibre on the same side of the frame. The rollers are rotated so that the knots travel through 360 degrees around the support and then the direction of rotation of the rollers is reversed so that the knots travel back to their original position. Thus the fibre reciprocates over the two rollers. Alternatively, the two ends of the fibre may be tied together in which case the rollers may be rotated in one direction only so that the knot eventually passes through its starting position.
