Title: Improvements relating to the mounting of shaft bearings
IPC: F16C35/077
Filed: 1946-08-01
Abstract: 632,711. Mounting bearings. BRITISH THOMSON-HOUSTON CO., Ltd., WOODFIELD, T. H., and MORTON, C. J. Aug. 1, 1946, No. 23005. Addition to 620,566. [Class 12 (i)] The ball-bearing mounting of the parent Specification is modified in that the base fingers provided on the adaptor for exerting axial pressure on the outer race form part of a separate member which is secured to the cap member, the fingers of which exert radial pressure on the outer race. By making the adaptor in two parts the degree of resiliency of the two sets of fingers may be varied. A washer 1 of sheet-metal has spring fingers 2 bent up from it to form a caplike portion at right angles to the washer, this part being similar to the cap described in Specification 632,772. To the exterior of the base of the cap 1 is applied another washer 3 having spring fingers 4 bent over, but lying spaced from, the interior surface of the base of the cap 1. The two parts may be held together by this bending over of the fingers 4 or additional securing means may be provided. In use the radially-acting fingers 2 grip the outer race of a ball-bearing, Fig. 2 (not shown), forming a resilient packing between it and the surface of an opening in the housing, while the axially-acting fingers 4 bear against one end of the outer race. To protect the fingers 4 from undue compression, they have projections 10 on the underside of those parts which overlie the washer 1.

Abstract: 1426518 Monitoring filaments SOC DE LA VISCOSE SUISSE and MASCHINENFABRIK RIETER AG 16 May 1973 [19 May 1972] 23415/73 Heading G1M A moving filament or bundle of filaments is monitored pneumatically by guiding it at right angles to and through two air-streams directed towards one another, the air-streams being of different intensities, the filament or bundle of filaments being guided nearer to the air-stream of higher intensity, and the pressure changes of the air-stream of smaller intensity being measured. Air is supplied to nozzles 5 and 7 via restrictors 10, 12, and the pressure in conduit 8 leading to nozzle 7 is monitored by a pressure amplifier 14. Nozzle 5 is narrower than nozzle 7, is nearer the filament 1 than nozzle 7, and is supplied with a higher pressure than nozzle 7, the arrangement being such that in the presence of a filament air issues from both nozzles 5, 7, but in the absence of the filament the air jet from nozzle 5 prevents air leaving nozzle 7. The filament is guided by outwardly open guide slots 3a, 3b and inwardly open guide slots 4a, 4b.

Abstract: 1536748 Sintered fibre-reinforced articles WESTINGHOUSE CANADA Ltd 8 June 1976 [24 Dec 1975] 23589/76 Heading C7D  A composite article is formed from a matrix material and reinforcing fibres by forming a plastics tape containing the matrix material, arranging the fibres in a regular pattern between two layers of tape, cutting the tape into a plurality of laminae, arranging the laminae into a form to reproduce the shape of the article, and subjecting to hot isostatic pressing. The method is used to produce turbine blades and other engine components from superalloys reinforced with fibres of W, Mo, SiC or graphite. Powdered superalloy is mixed with a resin, e.g. polymethacrylate, and formed into tapes 7, 8 having a plastic backing, the tapes being fed from reels 9, 10 above and below fibres 5 fed from reel 6, passing through rolls 11, which may be heated, to produce a tape containing the fibres, after which the plastic backings 16 are removed. Laminae cut from the tape are placed inside a container in the desired shape, e.g. an airfoil Figs. 3 and 4 (not shown), the container is evacuated, filled with H 2 , heated, e.g. to 300C, to decompose the binder, the spaces (20) are filled with superalloy powder and the whole is evacuated, sealed and hot isostatically pressed e.g. at 900-1300C and 10,000-30,000 psi. The container may be of steel, in which case it is removed by pickling, or of corrosion resistant alloy when it may remain as part of the article. Alternatively the container may be a ceramic mould formed by the lost wax process, which, when filled is placed in a metal container, the space between the container and ceramic mould being filled by SiO 2  or a metal halide, e.g. NaCl, BaF 2 . The composite article may be hot forged if necessary, and may be given an aluminizing coating by pack diffusion or vacuum evaporation. Superalloys containing as main ingredients Ni-W-Co-Cr-Al and Co-Cr-Mo are referred to.

Title: Improvements relating to the oxidation of residual petroleum waxes
IPC: C10G73/38
Filed: 1958-07-23
Abstract: Microcrystalline wax is oxidized by passing a free oxygen-containing gas through the molten wax using a catalyst consisting of a lead soap of a C12-C20 fatty acid, e.g., lead stearate, alone or in admixture with another oxidation catalyst such as potassium permanganate.  The wax is that obtained on de-waxing the de-asphalted residue obtained by vacuum distillaiton of the residue remaining after the distillation of crude petroleum at atmospheric pressure.  The wax may be used as such or after at least a partial de-oiling by recrystallization. Its oxidation may be effected at 140 DEG  - 200 DEG C., preferably until the oxidate has a saponification number of at least 5.  Examples describe the preparation of such oxidates having S.N.s of 5 - 76 and also, for comparison, an oxidate of S.N.4 wherein KMnO4 is used as sole catalyst.  The products may be used as dispersing or emulsifying agents, e.g., as described in Specification 902,623.ALSO:Surface-active agents are prepared by oxidising a micro crystalline wax by passing a freeoxygen containing gas through the molten wax using a catalyst consisting of a lead soap of a C12-C20 fatty acid, e.g., lead stearate, either alone or in admixture with another oxidation catalyst such as potassium permanganate.

Abstract: 781,772. Pushing jacks. DEMAGAKT.-GES. Aug. 16, 1954 [Aug. 14, 1953], No. 23736/54. Class 78 (3). A thrusting mechanism for advancing coalextracting machinery 5 towards a coal face comprises a double-acting fluid pressure jack 8, 9 and a reaction strut 11 connected to the jack by a rigid distance-piece which is of sufficient length to leave a space to permit the operator to move thereover. The distancepiece comprises a pair of telescoping channel members 15, 17 interconnected by a releasable and reversible spring-loaded pawl 20 on member 15 which engages holes 18 in member 17. The arrangement is such that with the chamfered face of the pawl in the position shown, reciprocation of the piston 8 in cylinder 9 produces a step-by-step movement which alternately advances the machine 5 and extends the distancepiece ; whilst when the pawl is reversed reciprocation of the piston alternately retracts the distance-piece and moves the strut towards the face. A further fluid pressure jack 27, 28 is provided to advance the strut towards the jack in one movement when the pawl is released. In a modification (not shown), the distancepiece consists solely of a jack. The strut 11 is shown as a pair of telescoping members held in their adjusted position by a locking pin, but according to a further modification (not shown) it may consist of a fluid pressure jack. The Specification states that all the jacks may be controlled remotely.

Title: Improvements in or relating to the winding parts of clockwork
IPC: G04B11/02
Filed: 1919-09-27
Abstract: 150,185. Bapty, S. L. Sept. 27, 1919. Driving-mechanism, main spring and weight.- In clockwork wherein the winding-mechanism comprises a metal spindle, a toothed wheel, a ratchet or clutch, and a driving-spring or drum with weight and cord, the clutch consists of a closely coiled spiral wire spring which embraces the spindle and is attached at one end to the driving-wheel, and is loose at the other. Fig. 2 shows the mechanism, the mainspring or the like being omitted. The driving-wheel C is mounted on a bush D rotatable on the spindle A, and the spring clutch B is forced on to the spindle and attached at one end, which is straightened to form a flexible arm, to the driving-wheel by means of tongues stamped up from the latter. During winding, the spindle winds up the driving-spring and has no action on the spring clutch. When the main spring unwinds, the spindle is rotated in the reverse direction and tends to coil up the spring B, which thereby grips the spindle and so rotates the driving-wheel. The latter drives the clockwork mechanism.
