Patent GB-171409-A (GB)
Title: Shaft retarding means
IPC: F01L1/053
Filed: 1921-11-14
Abstract: 171,409. Wills, C. H. Nov. 12, 1920, [Convention date]. Fluid-pressure.-A drag or retarding effect is exerted upon a rotating shaft to prevent noise due to back-lash in gearing, the arrangement being such that the retarding effect is automatically decreased as the speed of the shaft increases. As applied to the cam-shaft of an internal-combustion engine in order to prevent noise caused by back-lash in the toothed driving gear due to the varying resistance offered by the spring-controlled valves, a brake is arranged on one end of the shaft. This brake comprises an outer double-cone member 11, preferably of bronze, fixed to the shaft casing 12, and an inner steel member made in two parts, one part 13 being longitudinally movable on the shaft, the inner and outer members being pressed into engagement by a spring 14. An aperture 16 connects the interior of the cam-shaft with the space between the parts of the inner member and lubricating oil can pass from the cam-shaft to the cone surfaces and then back to the shaft casing. As the speed of the shaft increases, centrifugal force causes an increased flow of oil between the coned surfaces thereby lessening the drag action, until the shaft rotates substantially freely and the device acts as a bearing.

Filed: 1957-09-27
Abstract: 807,820. Capsuling bottles. USINES A. VANDERGEETEN. Sept. 27, 1957, No. 30409/57. Class 125(2). In a rotary capsuling machine wherein the cap is surrounded by a crimping mould subjected to fluid-pressure, each head consists of a piston 13 reciprocated vertically by a stationary cam track 15<SP>1</SP> and carrying a cylinder 2 the lower end of which is closed by the crimping mould 5 so that as the piston descends, the cylinder descends until it is stopped by the bottle and then the fluid beneath the piston in space 26 is compressed to crimp the cap, a relief valve 27 allowing fluid to escape to the space 25 above the piston when the desired maximum crimping pressure has been reached. As the piston is raised, fluid can pass from space 25 to space 26 through flap valve 21. The spring- pressure on relief valve 27 can be varied by turning screw-cap 30. The piston and cylinder are urged apart by a spring 17.

Abstract: 364,206. Current and pressure meters. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Siemens & Halske Akt.-Ges.; Siemensstadt, Berlin.) Oct. 11, 1930, No. 30494. [Class 37.] A measuring instrument of the moving-iron circular coil type is constructed of a die-cast body, Fig. 4, carrying the coil, moving core and stationary core supports, the dial and the damping chamber 1. The body is provided with feet 2, 3 and arms 8, 9 with extensions 11, 12 on which the dial 10 is screwed. A downward extension 4 flanged at 5 at its lower end carries the coil spool which is centred on a flange 22 below the flange 5. A hole in the lower end of the extension 4 carries the lower support of the moving iron spindle the upper end of which, together with the pointer, is carried in a bridge 16 secured by screws to enlargements 15 at either side of the extension 4. The fixed core, or cores, is carried on a resilient split sleeve 7 of German silver, which is forced on to the flange 5 before the coil spool 18 is pushed on to the extension 4. A finger extension 20 of the sleeve 7 presses on and slides over the upper flange 17 of the coil spool 18 and serves to adjust the position of the fixed core, the adjusted position being fixed by filling a slot 21 in the extension 20 with shellac or other adhesive material to secure it to the flange 17. The core 17 of the coil spool 18 is provided with flanges 19 which are secured to the die-cast body by screws engaging apertures near the base of the two arms 8, the body being recessed, as shown in Figs. 2 and 4, to reduce eddy currents and to expose the finger extension 20 which moves over the flange of the coil spool.

Operation of eject key EJC when the cassette is in the record/play-back position parallel to the chassis moves a lever 32 in the direction of its length whereby a dependent part 31 thereon engages a leg 21b of a lever 21 which with the assistance of spring 26 pivots the receptacle 13 and cassette to the inclined position. The lever 32 also spring loads a second lever 35 including an upstanding portion 38 which engages a part 13c on one side 13a of the receptacle in its operational position, but when the receptacle moves to its inclined position step 38a on part 38 slips past the part 13c engaging forcibly the end 41b of a push out member which pivots and pushes out the cassette by its end 41a. The operating keys are arranged such that the eject key cannot be depressed when a play-back key is operated and the play-back key cannot be depressed with the receptacle in its load/unload position.

Title: Improvements in or relating to packing arrangements between relatively movable parts
IPC: F16J15/3224
Filed: 1957-10-01
Abstract: 827,564. Piston and stuffing-box packing. KNORR-BREMSE G.m.b.H. Oct. 1, 1957 [Oct. 2, 1956], No. 30705/57. Classes 122 (1) and 122 (5). A packing arrangement between relatively movable parts comprises an elastic packing ring 13 housed in a recess 5 in one of the parts and having two flexible limbs separated by a circumferential groove 15 opening towards that part, the limbs bearing resiliently against opposite side walls of the recess and the inner or outer periphery 21 of the ring contacting the other part and the arrangement being such that one of the limbs is deformed elastically by the sealed fluid to permit the fluid to enter the recess. As shown in Fig. 1, the recess 5, formed in a piston 1 is divided into two chambers 9, 11 by a web 7 integral with the piston and extending into the recess and beads 17, 19 on the ring engage the recess side walls. The outer periphery of the ring contacts the cylinder wall 23 and extrusion of the ring between the piston and cylinder wall is prevented by rings 25, 27. In operation, air pressure to be sealed and acting in the direction of the arrow forces the bead 17 away from the associated side wall, as in Fig. 2, and urges the bead 19 and the periphery 21 of the ring tightly against the other side wall and the cylinder wall respectively. In a modification, Fig. 3 (not shown), the packing ring is housed in a recess in a fixed part and its inner periphery bears against a movable part. In a further modification, the packing ring is of triangular cross-section and, in a still further modification, the web 7 is omitted.

Title: Process for the manufacture of zirconium oxychlorde
IPC: C01G25/04
Filed: 1935-11-08
Abstract: The mixed chlorides obtained by chlorination of a zirconium mineral containing iron are treated with water to obtain a hot solution of zirconium oxychloride, the solution is separated whilst hot from precipitated impurities and then cooled with agitation to precipitate crystals of the oxychloride which are finally washed with hydrochloric acid containing 20--25 per cent HCl.  The oxychloride content of the iron-bearing mother liquor may be recovered by concentration and itself be washed with hydrochloric acid to remove iron.  Chlorination of the mineral, such as baddeleyite, zircon, or favas, may be effected at 300--600 DEG  C. with phosgene or a mixture of carbon monoxide and chlorine, or the mineral mixed with carbon may be treated with chlorine.
