Title: Method for over-oxygenating the air supplied to a magnetohydrodynamic blast
IPC: H02K44/08
Filed: 1967-01-13
Abstract: <PICT:1119321/C1/1> In a burner arrangement for a magnetohydrodynamic conversion plant air supplied to the burner is enriched with oxygen supplied by the decomposition of higher oxides of polyvalent metals such as tin, iron or manganese existing as solids at temperatures of 400-1500 DEG  C. in the form of at least one higher oxide and at least one lower oxide.  Feed air flows through a lower temperature heat exchanger E and then through the overoxidation chamber 11 of a high temperature exchanger So containing the higher oxides. Following decomposition into lower oxides the material is removed from chamber 11 to enter a regeneration chamber R through which flows a low-temperature air stream entering at 17 and leaving at 18.  The exchangers E, So are supplied with heat by combustion gases issuing at 6 from the blowpipe T of the M.H.D. plant and the regenerated oxides are returned to the chamber 11.  In a modification regeneration takes place inside two exchangers So instead of in a separate chamber. The supply air heated to 1450 DEG  C. flows through a tube of zirconium oxide containing 10% magnesia and surrounded by air at 1350 DEG  C., the supply air passing through the tube being enriched with oxygen.

In a ring twisting machine in which each ring holder 2 may be detached from the traverse rail 1 and lowered on a guide rod 5 to a position in which a full package on the associated spindle may be doffed, inter co-operating catch members 647 are provided on the traverse rail and ring holder respectively, one of the members e.g. member 7 being displaceable against resilient means e.g. a spring 9 to a disengaged position so that the holder may be lowered, while in the engaged position shown in Fig. 3 the catch members react so as to press the holder 2 against the rail 1. In the form shown, rotation of a cam 10 by a handle 11 displaces plate member 7 to disengage the ring holder so that it may be lowered to its doffing position. When a new former is placed on the spindle a transfer tail may be wound thereon by raising the ring holder to an intermediate position. This is effected by rotation of the handle 11 so that a lever 17 normally spring urged against the underside of the ring holder is rotated by an arm 15 and pin 16 on the lever 11 to bear against a fixed member in the machine frame and raise the holder to its intermediate position. The transfer tail is then wound. The ring holder is next fully raised into engagement with the traverse rail. A carriage 3 which is provided on the ring holder 2 to guide it on the rod 5, has two upstanding pins (not shown) engageable in a member mounted on the traverse rail to locate the holder in its engaged position.

Abstract: 909,105. Shoe bottom pressing-machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. (United Shoe Machinery Corporation). Jan. 22, 1959 [Jan. 23, 1958], No. 2269/58. Addition to 747,019. Class 17 (1). In a shoe bottom pressing-machine according to Claim 2 of the parent Specification a high pressure between the heel seat and the heel pressing block 10, and a reduced pressure between the shank portion and the auxiliary devices 14, 16 are brought about by separate power means. The shoe is pressed upwardly by an abutment-plate 64 first with light pressure when piston 50 is moved in bore 46 in the larger piston 44 by fluid from conduit 144, and then with greater force when piston 50 is moved in cylinder 40 by fluid from conduit 140. Rotation of piston-rod 51 is prevented and its upward movement limited by pin 63 engaged in groove 65. A rubber annulus 66 permits slight universal tilting of the plate 64 on its supporting- block 62 which is adjustable on a member 60 secured to rod 51, and the plate, which is held in position by spring 72, is locked frictionally by engagement of a spherical projection 68 with a conical surface 70 on block 62. Blocks 14, 16, which are normally held in raised position by spring 80, are swung to operative position by movement of piston 108 which acts via spring plunger 124, equalizing lever 100, levers 92, equalizing levers 90, and rolls 86, 88, the movement of levers 92 being limited by stops 81, and rotation of piston 108 and lever 100 prevented by pin 102 engaged in slot 128. Fluid under pressure is supplied from accumulator A via valve V1, operated by solenoid So, and pressureoperated valve V2, with fluid-operated valve V3 controlling the flow to bore 46, sequence valve V4 and manually-adjusted pressure-reducing valve V5 controlling the flow to cylinder 40, and sequence valve V6 and manually-adjusted pressure-reducing valve V7 controlling the flow to cylinder 114. Solenoid So is controlled by a pneumatic timing device T. At presentation the shoe presses upwardly a spring-pressed rod 180 which acts via arm 200 and lever 206 to actuate button 196 which operates the timing device. On continued movement of rod 180, screw 212 disengages arm 200 and lever 206. Location of the shoe is facilitated by a V-shaped heel abutment 220 which is urged forwardly by a plunger 226 to a limit determined by adjustable stop-screw 228. When the shoe is released after pressing it is urged forwardly and drops into receiver 230. A thin metal sheet 22 preferably covers the surfaces of blocks 10, 14, and 16 which are heated by independentlycontrolled elements 240, 242, 244.
