Title: Continuous process for preparing uranium hexafluoride from uranium tetrafluoride and oxygen
IPC: C01G43/06
Filed: 1960-03-15
Abstract: Uranium hexafluoride is prepared by introducing dry finely divided uranium tetrafluoride and an oxygen-containing gas into a fluidized bed of dry uranyl fluoride at 600 to 900 DEG C., thereby converting the tetrafluoride feed to a mixture of uranyl fluoride which remains in the bed and uranium hexafluoride which is removed overhead and recovered in cold traps.  The excess uranyl fluoride building up in the bed is removed and converted to uranium tetrafluoride feed by reduction with hydrogen followed by hydrofluorination.  The hydrogen fluoride-containing effluent from the reduction and hydrofluorination reactors may be employed to treat a uranium oxide initial feed which is thereby converted to uranyl fluoride; the latter is then reduced with hydrogen and hydrofluorinated for passage to the main reactor as uranium tetrafluoride.  The uranium tetrafluoride concentration in the fluidized bed of uranyl fluoride is less than 25% and preferably less than 10%.  Carbon monoxide may be added to the fluidizing oxygen stream to maintain the reaction heat and the reactant gases may also be preheated by passing them around the outside of the reactor above the bed level; this also serves to cool the product gases which assists the filtering of entrained solids and condensible by-products.

Title: Overspeed Brake for Rotative Engines
IPC: F16D51/02
Filed: 1969-02-20
Abstract: 1,189,440. Turbine overspeed brakes; engine stop gear. GENERAL MOTORS CORP. Feb.20, 1969 [May 20, 1968], No.9234/69. Headings F1K and F1T. The invertion relates to an overspeed brake device for rotating engines and is described with reference to a turbine, the brake device being responsive both to speed of the turbine and to the torque transmitted so that the brake device is operative upon occurrence of overspeed and reduction in torque consequent upon loss of load. The turbine shown comprises a rotor disc 10 which is connected to an output shaft 13 through a coupling comprising a drum 17 which is connected to the shaft by means of a plurality of inclined spokes 18, and to the rotor disc 10 by means of a face coupling comprising intermeshing splines 19 on the drum and splines 21 on the rotor disc. The rotor disc is urged towards the drum by means of a screw nut 25 engaged on the shaft 13. The drum 17 rotates within a fixed brake drum 27 which is part of the stator structure 15. At normal operating speed the drum 17 has small clearance within the brake drum 27, the tension in the spokes 18 exerting a radial inward force on the drum 17. Upon loss of load however the drum 17 expands as a result of the loss of tension in the spokes and also due to the increase in centrifugal effect as the speed increases above normal. The drum 17 thus rubs against the brake drum so retarding the rotor disc before destructive overspeed occurs. The drum 17 may be formed of material having a high coefficient of thermal expansion than the brake drum 27 so that the drum 17 expands relative to the drum 27 as a result of the heat generated consequent upon the rubbing effect.

Filed: 1946-03-26
Abstract: 609,964. Grinding twist drills. FOUQUET, E. March 26, 1946, No. 9380. Convention date, July 28, 1941. [Class 60] [Also in Group XXIV] In grinding a flute in a rod of hardened steel the diameter of which does not exceed substantially ten mm., by giving the rod a longitudinal and twisting motion relative to a grinding wheel rotating at high speed, the flute is ground in a single almost instantaneous operation, the duration of which does not exceed about one second, whereby the shavings removed by the grinding wheel are rendered incapable of transferring their heat to the mass of metal from which they have been removed. The grinding wheel 2 is driven by belt 7. The rod 1 is secured by a screw 8 in a holder 9 having a shank 22 received in a sleeve 10; a screw 24 carried by the sleeve 10 engages either end of a diametral hole 23 in the shank 22 so that the drill can be indexed through 180 degrees. The sleeve 10 is mounted in bearings 20, 21 for axial and rotational movement and has a helical groove 11; an endless cable 12 is wound round part of the groove and round a pulley 14 mounted on a shaft 15 carrying a lever 28; by throwing over the lever 28 a very rapid pull is imparted to the cable which gives a very rapid traverse, accompanied by rotation of the sleeve 10 and rod holder 9. The drill is also supported by a block 26. For a drill of three mm. diameter having a flute about fifty mm. long, the linear peripheral speed of the grinding wheel is at least eight mm. per second and the operation is performed in not more than one-quarter of a second.

Title: Improvements in Disc Brakes
IPC: F16D55/00
Filed: 1967-02-28
Abstract: 1,152,528. Disc brakes. KELSEY-HAYES CO. 28 Feb., 1967 [28 Feb., 1966; 11 April, 1966], No. 9507/67. Heading F2E. In a disc brake of the floating caliper type, a housing 53, which is guided for movement normal to the disc 21 by a torque spider 39 having arms embracing it and which includes a cylinder bore 67 containing a piston 65 for applying one pad 69 to the disc, is supported also by a yieldable, resilient support member 103 in the form of a plate comprising a flange 105 secured to the torque spider, an axial portion 111, a weakened portion 127 forming a first flexible hinge, a radial portion 109 and a pair of inwardly bent arms 113, 115 joined to the portion 109 by weakened portions 129, 131 which together form a second, parallel flexible hinge, the arms 113, 115 being secured to the housing 53 at a position such that, when fluid is supplied to the cylinder bore, the member 103 is stressed such that the reaction force acting on the housing to apply the other pad 89 is resisted by a substantial axial spring force exerted by the member 103. The weakened portions yield to automatically adjust the housing for wear and to cause the pad 89 to remain in light rubbing contact with the disc when the brake is released. Pins 80, engaged in apertures 81, 82 in the housing and slidable both in the backing plate of pad 69 and in a grommet 132 secured in an aperture of the torque spider arms, resist axial movement of the housing sufficiently to prevent pad 89 from engaging the disc with more than a light pressure when the brake is released. The disc is of ventilated type, having webs 37 between spaced discs to prov i d radial air passages 35. In the modification of Fig. 9, the yieldable support member 141 is of generally rectangular configuration having inner axial, radial and outer axial portions 149, 147, 151 each strengthened by lateral flanges 159, 165, 169, respectively, to leave relatively weak angle portions 155, 157 which provide the flexible hinges.

Title: Improvements in or relating to a device for the mass production of shoes
IPC: A43D25/10
Filed: 1962-03-14
Abstract: 960,766. Shoe bottom presses. SVIT, NARODNI PODNIK. March 14, 1962 [June 1, 1961], No. 9771/62. Heading A3B. A device for pressing shoe-soles to shoes comprises a support structure having an upright member located alongside a conveyer and an upper angled member 104, 105 overhanging the conveyer, the structure being raised and lowered by a rack and pawl mechanism operated by a cam 126, a bracket 140 and a press mould 107 pneumatically or hydraulically operated through a pressure distributing device 131 by cams 137, 139 fixed upon a shaft 65, the drive of the shaft being synchronized with that of the conveyer links so that movement of the support structure occurs only when the conveyer is at rest. In a cycle of operation, as the shoe last 30, with a shoe vamp already tightened upon it, the bottom covered with adhesive and a shank stiffener and sole already in position, approaches the working place, cam 126 rotates, lifting the follower 122 with a lever arm 120 causing it to disengage pawl 123 from the rack 125. Arm 120 then abuts a stop 127 on jibs 104 causing the press mould 107 suspended on jibs 104, 105 to rise. These jibs are guided by rollers 103 carried by guide ways 101, 102. When the last is in position, the follower 122 runs down the periphery of cam 126, so that the diaphragm 116 of the press mould 107 places itself on the sole and is secured in position by the re-engagement of pawl 123 with the rack 125. The cam 137 then releases a button 136 enabling diaphragm 134 to free aperture 156, and thus the pressure medium inflates the cushion 113 through tube 115. As the shaft 65 rotates, button 136 is pushed back, thus stopping the supply of pressure medium and cam 137 releases button 139, so that the medium contained in the pressure mould escapes through apertures 154, 157, 158, 155. The cam 126 then lifts the press mould and the shoe last 30 advances by one pitch of the chain link 20. Three holes 144, 145, 146 in jibs arms 104, 105 enable the press mould 107 to be located at a higher or lower level in relation to the conveyed shoe-lasts. An adjustment screw 147 is screwed into a member 148 connecting the guides 101, 102, abuts the cross-piece 106 and enables the position of the press to be adjusted vertically. Also secured to the front side of the guides 101, 102 is a bracket 140 on which is mounted a slide 141 carrying a support 143 to the tip of the shoe last.
