Filed: 1944-02-28
Abstract: 575,081. Bearings. LUCAS, O. D. Feb. 28, 1944, No. 3612. [Class 12 (i)] A bearing unit for a shaft to be used in place of a ball or roller bearing consists of a unitary structure comprising a sleeve 1 rotatably mounted in a race 2 formed by a plurality of rings arranged face to face and each having a cut 4 therethrough to allow expansion, under load, against an outer cage 3 which encloses the race rings. The inner facing edges 9 of the race rings are bevelled to provide a lubricant channel for lubricant supplied through an aperture 5 in the cage, which aperture is in registry with the cuts in the rings to provide a duct connecting with such channel. The outer cage has spun-over end flanges 7, 8 to retain the race rings. The sleeve 1 as shown is selfaligning as well as rotatable. The race rings may be of a laminated phenol-formaldehyde resin and the sleeve of non-corrodible steel ; the race rings and sleeve may be treated with colloidal graphite to reduce friction.

Title: Improvements in Moulding
IPC: B29C45/26
Filed: 1967-01-25
Abstract: 1,157,844. Injection moulds. CELANESE CORP. 25 Jan., 1967 [1 Feb., 1966], No. 3664/67. Heading B5A. In apparatus for injection moulding crystalline plastics in the molten state, a jet of the material issuing from a gate 18 into a mould cavity 14 impinges on an upstanding retractable projection 20 which breaks up the jet and prevents premature solidification of portions of the material. The gate has a width of at least 0À1 inch. When the mould cavity 14 is full, projection 20 retracts under pressure of the injected material against the action of a spring 24 in a chamber 21. Alternatively, the spring 24 may be strong enough to maintain the projection partly within the mould cavity when this is full so as to leave an impression in the moulding. The depth of the impression is a measure of the pressure of the molten plastics material. In an example, to produce a “ inch thick standard ASTM-type I tensile bar, projection 20 had a diameter of 0À25 inch and was directly in front of the gate 18, the distance between the edge thereof and the projection being 0À062 inch and that between the top of the projection and a cover (not shown) for the cavity being 0À09 inch. The injected material may be an oxymethylene copolymer, acetal copolymers and homopolymers.

Filed: 1917-03-15
Abstract: 114,326. Irwine, H. G. March 15, 1917. Projectiles; projectile fuses.-Consists in apparatus specially designed for dis-assembling parts of projectile fuses which comprise a centrifugal shutter mounted in a body part and enclosed by a sheet-metal cap, the object being to enable the cap to be readily removed if the shutter mechanism is found, by testing, to be defective. The apparatus comprises a socket a having an internal annular shoulder a<1>, and a vertically mounted plunger b. The socket is adapted to receive the body k which carries the shutter m, while the width of the shoulder a<1> is such as to allow the flange h<1> of the cap h to rest thereon, as shown in Fig. 3. The plunger b, which in the apparatus shown is spring-controlled and is actuated by a hand-lever e, when depressed passes through a hole in the cap h, and forces the shutter m and body k out through the lower part of the socket, the cap being retained by the shoulder a'. The mouth of the socket may be trumpetshaped. The Provisional Specification describes also a modification in which the socket consists of a spring clip which can be clamped around the fuse parts by means of a screw and nut.

Title: Improved Apparatus for the Manufacture of Bolts.
Inventor: FERNAND CHARLE
IPC: B21K1/44
Filed: 1918-03-04
Abstract: 113,967. Charle, F. March 2, 1917, [Convention date]. Forging bolts.-A machine of the drop-hammer type for making bolts comprises a driving shaft 4 on which is loosely mounted an eccentric drum 1, to the periphery of which the hammer is connected. An arm 5 on the shaft carries a roller 6, which, during a portion of its movement, engages a roller 7 carried by the drum, and rotates the drum. When the rollers separate, the hammer falls, and the punches 23 enter the dies 22 carried by an intermittently rotating turret 9. The turret is rotated by the shaft 4 through a crank, a pawl 11, ratchet 12, bevel-wheels 14, 15, shaft 16, and change-speed gear 17, 18, 19. A pin 20 on the hammer passes into a recess 21 in the turret to centre the matrices 22, and by pressing on a spring-rod 24, operates a cam-lever 25 to disengage the crown-wheels 27, 29, and allow springs 30 to raise the plungers 31 against the ejectors 32. When the hammer rises, the spring 33 forces the wheels 27, 29 into engagement, and a roller 34<a> raises a pawl-lever 34 against the spring 39 and thus operates a sprocket wheel 35, chain 36, and pinions 37, 38 to return the plungers 31. The shaft 4 is driven bv worm gearing, and may bo operated by a hand-wheel 8.

Title: Improvements in and relating to the production of metal-metal oxide alloys or compositions
Inventor: LEVER FRANK MERCER
IPC: H01H1/0237
Filed: 1964-01-29
Abstract: A method for making a metal-metal oxide composition comprises treating a mixed solution of compounds of the metals (at least one of which forms an unstable oxide and at least one of which does not) with a solution of alkali metal or ammonium hydroxide or carbonate to cause co-precipitation of the hydroxides and or carbonates, reducing the unstable oxide-forming metal compound with a solution of a reducing agent (e.g. hydrazine) and then treating the mixture to give the metal-metal oxide powder mixture. Alternatively the reducing agent may be included with the hydroxide and/or carbonate treating solution. The treatment of the reduced mixed precipitate may be heating at 450-750 DEG C.  The original metal compounds may be nitrates, citrates, sulphates, oxalates or chlorides, the metal having the reducible oxide may be Ag, Cu or Ni and the other metal may be Cd, Sn, Pb, Mg, Si, Al or Be. The powder mixture may be sintered to form a coherent body.

Abstract: 1,049,203. Welding by pressure. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Jan. 29, 1964, No. 3811/64. Heading B3R. [Also in Division G1] In securing a flexible metal suspension strip to a part of an instrument moving system or to a support for the system, the parts are subjected to pressure and are relatively vibrated to weld them together. The vibrations may be ultrasonic and with the strip clamped to the other part in jaws one or both of the jaws is vibrated to vibrate the strip and/or the other part. The strip may be employed where the moving system is suspended with the strip under tension and torsion or wherein the strip is a coiled spring in a moving coil instrument. The strip may be secured at both ends by the ultrasonic welding.

Title: Improvements in and relating to the moulding of plastic materials
IPC: B29C45/54
Filed: 1945-02-15
Abstract: 592,056. Injection-moulding machines. GOLDHARD, F. K., and PRENN, D. D. Feb. 15, 1945, No. 3880. [Class 87 (ii)] The mould is partly filled by a first pressureapplying means, which is then sealed off, and further material is injected under higher pressure by a second pressure-applying means. In the form shown in Fig. 1, granular material is fed from a hopper 1 to the screw 4, which conveys it through the space A (where it is plasticised, 2 being an electric heater and 3 a thermostat) to B (where further heat may be supplied) and through the passage C into the mould. When the back-pressure on the screw 4 is sufficient to overcome the spring 9 it moves axially, breaking the switch 8 and stopping the motor 5. The motor may be stopped by other means, e.g., an overload trip, a time device, or a hand switch. Second stage pressure is then exerted by the plunger 10 which is advanced by the hydraulic piston 11, closing off the space B from the space A. Finally, when equilibrium is reached between the hydraulic pressure on the piston 11 and the back pressure on the plunger 10, the valve 19 opens and admits pressure fluid behind the piston 13 which moves forward driving the plunger 14 into the bore C and sealing it off from the space B and exerts the final moulding pressure. The mould halves 21, 22, which may be water-cooled, are clamped together by dowels 26 engaged by tapered locking bars 28. When the mould is opened the hardened material in the space C is pushed out by the plunger 14 and the moulded article is ejected from the moving mould half 21 by ejector pins 23. The injection apparatus may be vertically adjustable to suit moulds of different sizes. In a modification, Fig. 3, the plungers 10 and 14 are independent and the feed device 4 is driven by a geared motor with an overload trip. An additional heater 2a is shown. In either form electrically operated valves may be used to seal off each pressure stage space from the preceding one.
