Filed: 1943-02-17
Abstract: 564,842. Couplings. ROTHERY, J. S. Feb. 17, 1943, No. 2644. [Classes 44 and 89 (ii)] [Also in Group XXXIII] A device for testing the response of quickrelease couplings to their release mechanism, such as those used in glider tow ropes, comprises a piston 1 working in a cylinder 2 adapted to be attached to or provided with a part 8 corresponding to one of the elements of the coupling and a counter thrust member 9 adapted to press against the part carrying the release jaws 24 of the coupling when the piston is put under pressure by means such as a hand screw-pump 23, a gauge 18 indicating the pressure applied. Oil or grease is used as the pressure medium which fills a hollow stem 15 and communicates with the working space above the piston through passages 17. The part 8, which may be replaced by elements of other form to suit other types of coupling, is screwed onto a piston-rod 5 passing through a gland 4 in a cylinder head 3. Pressure fluid is introduced through a nipple 20. The release mechanism is actuated while the coupling is loaded by the device and its response noted. A number of similar couplings loaded to the same degree and controlled by a single release device may be tested to determine whether they uncouple simultaneously or not by listening to the resulting clicks as they release. A spring 7 restores the parts to normal position so that the pump pressure is released. According to the Provisional Specification an air cushion may be introduced into the hydraulic system which expands when the coupling is released and increases the loudness of the " click."

Title: Improvements in or relating to machines for use in the manufacture of shoes
IPC: D05B15/00
Filed: 1941-02-27
Abstract: 548,344. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Feb. 27, 1941. No. 2654. [Class 112] In a machine for operating automatically upon a shoe supported on a jack such, for example, as described in Specifications 289,142, [Class 112], and 527,291, the main drive is from the motor shaft 110 through gears 112, 114, gears 118, 120, and a main clutch 122, 130. The clutch part 122 is mounted freely on a shaft 124 and the part 130 is splined to it. The part 130 drives the sewing cam-shaft 132 through gears 134, 135 and the pattern camshaft is driven from the shaft 124 through a clutch 214, 216 and a gear 218 on the shaft 212. In the stopping operation, the sewing cam shaft is stopped and then reversed by means of a clutch 150 and a reverse drive drive including gear 146, shaft 141 and gear 142. On reversal, the shaft is positively stopped by a bolt 171, Fig. 4, on a lever 167 which enters a slot 175. The shaft 124 is reversed.in this action and the pattern cam-shaft drive is therefore broken by opening the clutch 214, 216. At the same time an eccentric 278 is coupled by a clutch 282, 284 to a low-speed shaft 276 and is used to complete the rotation of the pattern cam-shaft. The clutch 150 is closed by means of a lever 156 when the normal oscillation of the lever is stopped by the engagement of a pin 164 with its normally free end. During running, the pin 164 is held below the lever 156 by means of a lever 190, Fig. 4, and a lever arm 186. When the treadle rod 140 is released and the main clutch lever 137 rises the lever arm 186 moves from the lever 190 and permits a spring 198 to push the pin 164 upwards. The pin 164 is carried by a slide 166 and as the clutch 150 is closed the slide moves and, through linkages 336, 334, gives an up and down movement to a rod 332. The rod 332 in its downward movement engages a pawl 328 and moves a lever 290 to close the clutch 282, 284 and open the clutch 214, 216. To this end, the lateral position of the rod 332 is determined by a lever 340 resiliently coupled to a lever 342 which is given a positive movement from the pattern cam for the primary purpose of releasing the clutch treadle rod 140. The lever 290 controlling the clutch part 284 carries a bowl 310, Fig. 7, lying in a V-shaped recess 312 on a lever 300. This lever is urged by a spring to the right and normally holds the lever 290 in mid-position. Movement of the lever 290 either up or down moves the lever 300 to the left so as to open the pattern cam-shaft clutch 214, 216. The lever 290 is mounted on a spindle 294 which carries a pin 314 projecting through a clearance hole 316. The spindle 294 carries a hand lever and, by it, the lever 290 can be moved to positions in which a the clutch 286, 284 only is closed and b all three clutches 214, 216; 282, 284 and 286,284 are open. The clutch 286, 284 is used for giving a reverse rotation to the pattern cam-shaft.

Abstract: <PICT:0897904/III/1> Anhydrous halides of aluminium, barium, boron, chromium, niobium, hafnium, manganese, molybdenum, rhenium, silicon, tanatlum, thorium, titanium, tungsten, vanadium, and zirconium, of at least 99%, and preferably at least 99,5%, purity, are prepared by halogenating a source of the metal, for example, an ore, compound, or alloy, in a graphite-lined reactor at a temperature at which the metal halide product is a vapour, and in the presence of sufficient halogen to provide an excess of at least 10% above that consumed in the halogenation, the halogenation taking place in the presence of sufficient quantities of a carbonaceous oxygen-accepting material, for example petroleum coke or carbon black, to combine with all of the oxygen in the source material, and separating the desired metal halide product from the reaction gases by fractional condensation. The halogen gas may be preheated at least to the temperature above which the metal halider product is no longer a solid.  The source material and carbonaceous material may be pelletized together by means of a suitable binder.  The Figure shows a suitable apparatus for carrying out the invention, in which chlorine gas entering at 15 is preheated in graphite tube 17 which is surrounded by finely divided carbon 18 acting as insulation.  The tube 17 is heated electrically.  The heated chlorine enters the reactor 19 which is lined with graphite 21, and for example, chromium-oxide-carbon pellets are fed in from hopper 23.  The reaction gases pass into the graphite-lined cyclone 27, where entrained solids are separated, and then to the condensor 33 where chromic chloride is condensed and removed via line 37.  Any chromic chloride remaining in the gases is removed in separator 35.  The waste gases are neutralized with sodium hydroxide solution in column 45 and vented to the atmosphere.  The recycle line 47 is employed during the starting up of the process.
