Title: Improvements in or relating to a Change-Speed Gearing and to Associated Control Means.
Inventor: ABBOTT RANDLE LESLIE
IPC: F16D23/06
Filed: 1966-01-12
Abstract: 1,172,982. Variable-ratio gear and control. AUTO TRANSMISSIONS Ltd. 21 Nov., 1966 [12 Jan., 1966], No. 1363/66. Headings F2C and F2D. In a planetary change-speed gear, drive ratios are established by a synchronized positive clutch-sleeve 68 (Fig. 1), actuated by a snapaction toggle (Fig. 3). The under- or (as shown), over-drive epicyclic gear follows a main vehicle change-speed gear (not further described), and comprises a driving planet carrier 17, a driven annulus 24, and a reaction sun 25, the sun being alternatively clutched to the carrier 17 for one-to-one directdrive or locked to a stationary housing 14 by the synchronized engagement of the dog-clutch sleeve 68, axially slidable from a central neutral position, to clutch dog teeth 66, 64 on the carrier and housing respectively. The clutch-sleeve 68 is moved axially by a slide 94 freely mounted on a bar 91 and biased by springs 97, 98 into a central neutral position. Movement of the bar 91 compresses the respective spring 97, 98 to move slide 94 only when synchronization is achieved after torque reversal. A manual lever 102, Fig. 3, which moves bar 91, has a toggle connection at one end such that it is biased by by a spring 125 into either of two extreme positions either side of a neutral dead centre position, the biasing spring 125 being stronger than springs 97, 98. A shown, the sleeve 68 slides on a hub 69 splined on an extension of the sun 25, coned balk rings 73, 74 abutting a friction brake surface 63 and clutch surface 64 respectively, and three circumferentially spaced plates 76 are urged radially out of slots in the hub 69 by expander rings 80 to engage recesses 81 in the sleeve 68, the ends of the plates being received in recesses in the balk rings to provide a lost motion connection. Lubrication of the gear is by means of a ring 49 on the annulus which dips into the lubricant and feeds it to a scoop 51 from which it is fed to the splined connection between the carrier 17 and input shaft 13 via bores 52, 53, 55 and 56, the lubricant then flowing between the sun and input shaft, and also through a bush 58 to be centrifugally fed into the path of a catcher plate 60 which deflects it into three hollow pins 21 carrying the planets to lubricate the planet bearings. The rest of the gearing is splash lubricated. A splined connection between the output shaft 20 and propeller shaft 36 obviates the necessity of providing a separate telescopic coupling in the propeller shaft. In Fig. 4 (not shown), the gearing is entirely splash lubricated, and the hub 69 is formed integral with the sun gear. The sleeve 68 is formed with three longitudinal slots (134) into which project fingers (143) having balk shoulders (144, 145), Figs. 5-8 (not shown), and formed on synchronized detector rings ( 141 ), (142) carried by, and spring-biased into engagement with, to allow slipping, a pair of hubs (135), (136), in splined engagement with teeth 64, 66 respectively.

Patent GB-809151-A (GB)
Title: Improvements in or relating to shock absorbers
Inventor: SIELY RONALD MAURICE
IPC: B64C25/60
Filed: 1954-01-18
Abstract: 809,151. Telescopic frictional shock-absorbers. AUSTER AIRCRAFT Ltd. April 18, 1955 [Jan. 18, 1954], No. 1450/54. Class 108(3) A shock absorber comprises contractible friction means 31 separate from, and co-operating with, telescopically disposed members 1, 8, and a wedging device 4 carried by the outer member 1 and co-operating with the means 31 so that on collapsing movement of the members 1, 8, the drag exerted by the member 8 on the means 31 urges the latter into closer engagement with the wedging device 4. This contracts the friction means 31 and increases the frictional resistance to the collapsing movement. As shown, applied to an under carriage leg for a helicopter, the members 1, 8 are tubular and the tube 8 is outwardly urged by a low-strength spring 27 which has no damping or suspension function. A friction band 30 surrounds the tube 8, and is itself surrounded by a contractible member 31 which may be in the form of a split ring, or a plurality of contractable shoes. Alternatively, the band 30 may be replaced by friction lining material disposed on the inner surfaces of shoes forming the member 31. The latter is engaged by a retaining spring 7, and has a conical shaped surface 32 which is adapted to engage a corresponding surface on the device 4. A rubber compression spring 3 is disposed between the device 4 and a flange 1a rigid with the tube 1. The member 31 is adapted to be urged into engagement with the device 4 by the action of a ring 6. A flange on the disc 6 carries pins 33 which engage in respective inclined slots 34 formed in a housing 1c rigid with the flange 1a. The ring 6 is adapted to be rotated by means of a member 35 which is rigid with two of the pins 33, and which is adapted to be locked by means of a lever 2 and spring catch 38 in a position corresponding to the innermost position of the ring 6 within the housing 1c. A tube 15 rigid with an end member 12 closing the inner end of the tube 8, is adapted to move relative to a guiding rod 17 rigid with a resilient disc 20 which is clamped by an annular ring 1b to the outer end of the tube 1. In operation, on compression from the position shown, friction damping afforded by engagement between the ring 30 and the tube 8, is progressively increased by the member 31 being urged into wedging engagement with the member 4. On extreme deflection, the tube 15 engages and fractures the resilient disc 20, and a rubber buffer 9 engages the disc 6. The shock absorber may be reset into its extended position by releasing the spring catch 38 from its engagement with the lever 2, and thereby rotating the member 35 to retract the disc 6 and so permit the member 31 to be withdrawn from the member 4. The tube 8 may be of heat conducting material.

Abstract: 745,974. Slicing-machines. GLOBE SLICING MACHINE CO., Inc. Jan 18, 1954 [Dec. 9, 1953], No. 1465/54. Class 28(2). The hand reciprocation of the substance carrier 10 of a gravity feed or other slicing machine, may be substituted by power reciprocation in which a pin 36 on an endless travelling chain 35 moves in a slot in a link 24 detachably coupled at will to the arm 12 of the substance carrier whereby the motion of the carrier is slowed down at each end of the reciprocation, thus giving smoother actuation and better slicing at each end of the stroke whereby the cut slices fall to make a more regular pile. The link 24 has a hook end 26 accommodated in a recess 20 in the arm 12, a pin of which fits into the hook end 26 and is clamped therein by a milled nut 23 thereby securing the whole link 24 to the reciprocating arm 12 of the substance carrier. This power reciprocating mechanism including the motor is attachable to the main frame of any gravity feed slicer and is cased in by casings (46 and 50, Fig. 1, not shown).

Patent GB-765851-A (GB)
Title: Improved process for the preparation of tertiary amines
Filed: 1954-01-18
Abstract: Tertiary methylalkylamines are prepared by reacting methanol and an alkylamine at elevated temperature in a zone containing a dehydration catalyst, the alkylamine consisting of primary alkylamines containing from 8 to 22 carbon atoms, or secondary alkylamines in which one alkyl group contains from 8 to 22 carbon atoms and the other alkyl group contains from 1 to 22 carbon atoms, holding the reactants within the zone until the reaction is substantially complete and a point is reached at which the content of secondary amines in the reaction mixture is reduced to within the range from 3 to 0.2 per cent by weight on a dry basis of the reaction mixture, and then terminating the reaction at that point. When the secondary amine content reaches this value, the primary amine content should be from 1.5 to 0.2 per cent.  Alternatively the reaction may be terminated when the secondary amine content plus primary amine content is from 4 to 0.5 per cent of the reaction mixture.  It is preferred to use a saturated or unsaturated primary alkylamine having, for example, 12 to 18 carbon atoms such as one derived from the fatty acids from fats and oils.  The preferred secondary amines have one saturated or unsaturated alkyl group containing 12 to 18 carbon atoms and the other containing 1 to 18 carbon atoms.  The preferred catalyst is alumina (bauxite) but silica, thorium oxide, tungsten oxide, nickel oxide or chromium oxide may also be used.  The reaction is generally effected at 200-400 DEG  C.  It is preferred to use a countercurrent liquid-vapour phase method, wherein heated methanol is passed into the lower part of a vertical reaction zone packed with dehydration catalyst, the heated liquid alkylamine is passed into the upper part of the zone and the product is removed from the bottom of the zone. Preferably the reaction zone is maintained at a temperature of 250-300 DEG  C. and a pressure of 100 to 1200 p.s.i.g.  Examples illustrate the method wherein methanol is passed over bauxite counter-currently to dodecylamine, didodecylamine, coconut oil amine, soya amine, di-"coco"-amine, or di-"hydrogenated tallow"-amine at 265-285 DEG  C. and 600 p.s.i.g.  Specification 765,852 is referred to.

Title: Improved air-cushion vehicle
IPC: B60V1/00
Filed: 1961-01-13
Abstract: 924,834. Vehicles supported by gaseous cushions. GENERAL MOTORS CORPORATION. Jan. 13, 1961 [Jan. 25, 1960], No. 1492/61. Class 4. A vehicle supported from the ground by a cushion of air comprises a platform 2 having beneath it a vented flexible diaphragm 12 of an area greater than that of the platform and hermetically attached at its outer periphery 14 to the platform. The diaphragm is made of an ethylene glycol terephthalic acid polyester and has an opening 18 defined by a bead 20 enclosing a metal ring 22. A blower 6 on the platform discharges air into the space 30 enclosed by the diaphragm and into a plenum chamber 32 formed between the diaphragm and the ground. The spacing of the opening 18 from the platform is controllable by a knob 28 on a shaft 26 on which is wound a cable 24 attached to a cross bar on ring 22, to vary the amount of air passing into the space 30. The blower is driven by a petrol engine, electric motor, or other prime mover, and on starting, first inflates space 30, lifting the platform clear of the ground, and then forms the air cushion beneath the diaphragm. The diaphragm deforms when obstacles are encountered, or to accommodate tilting of the platform under asymmetrical loading, the minimum clearance between the diaphragm and the ground remaining uniform. The blower may deliver air through apertures in the platform spaced laterally from opening 18 e.g. at the diaphragm periphery. The platform may be rectangular, and provided with handles for manual propulsion, though other propulsive means may be used.

Title: Process for the production of a tissue extract and of a serum activated thereby
IPC: C07K16/06
Filed: 1952-01-18
Abstract: Therapeutical agents are produced by making a wound in a preferably young and sexually immature animal, and after healing has set in, say in 7-15 days, removing the granulation tissue, extracting with acetone-ether to remove lipoids and produce a dry powder from which an aqueous isotonic extract is produced at 1-2 DEG C., the structural albumen being removed if desired by precipitation with acetone, ether alcohols, acids, or by fermentation, at pH 5.2-8.1 and dialysis filtration.  The acetone-ether may be concentrated in vacuos to a pasty consistency, taken up in alcohol under reduced pressure, and formed into an aqueous solution in a current of steam.  The two products may be used separately or in combination, either directly, or injected into an animal for the production of a serum, the blood being kept in a refrigerator until the serum has separated from the solid constituents of the blood.  Instead of extracting the wound granulation tissue, it may be first incubated in vitro, by implantation on a nutrient plasma prepared from the blood of mammals or domestic fowls, by adding anticoagulating agents, e.g. heparin, citric acid, and centrifuging.  During incubation, at 34-37 DEG C, the growing culture is sprayed with a nutrient solution.  After 2-5 days, the culture is isolated from the nutrient medium, and thereafter subjected to the acetone-ether extraction.
