Title: Improvements in or relating to universal joints
Inventor: BASTOW DONALD
IPC: F16D3/28
Filed: 1960-10-07
Abstract: 971,094. Universal joints; resilient couplings. BIRFIELD ENGINEERING Ltd. Oct. 2, 1961 [Oct. 7, 1960], No. 34394/60. Heading F2U. A Hooke's joint cross comprises two relatively circumferentially movable members drivingly connected by rubber or the like. In Fig. 2, one cross-member 5 has an aperture 10 of rectangular cross-section in which is mounted the other cross-member 4. The members 4, 5 are centred by a bush 13. Drive in either direction is through two of four rectangular cross-section elongated rubber pads 14 retained in grooves 15 of the member 4 and engaging the walls of the aperture 10. One of the forks may be flanged, welded to an adjacent tubular shaft, or form part of a sliding joint to accommodate axial " plunge." In Fig. 4, drive in either direction is through two of four rubber buffers 38 circumferentially arranged between interprojecting arms 33, 36, respectively, of cross-members 23, 24. The buffers 38, elongated axially of the joint, project from recesses 37 in the arms 33, 36 to engage plane surfaces 36a, 33a on the arms 36, 33, respectively, and are compressed to fill said recesses completely just before the two pairs of arms engage to limit relative circumferential movement. The change of buffer cross-section provides a variable torsional rate which may be arranged to be different for the two drive directions, e.g. drive and over-run. The members 23, 24 are centred by a bush 29 in the member 23 engaging a pin 28 connected to the member 24. Limited relative axial movement between the bush 29 and the pin 28 accommodates " plunge." The cross-members may alternatively be centred by a needle roller bearing. The cross-members may be coupled by a rubber bush forming a bearing between them.

During starting of an exhaust turbocharged engine, a piston compresor 10, driven at constant speed by an auxiliary engine, supplies air to an auxiliary valve controlled inlet port 9, excessive pressure in the piston pump delivery pipe at low turning speeds being prevented by a blow-off valve 26 through which excess air is delivered via pipe 27 to a receiver 3 feeding the normal inlet ports 2. A flap valve 33 prevents back flow through the compressor 31 of the air delivered through pipe 27. A valve operating lever 16 of the valve 17 is held in an operative position by a piston 19 urged to the left by the delivery pressure of the compressor 10; when the engine is operating normally, valve 23 is turned to connect pipe 22 to atmosphere, whereupon piston 19 is forced to the right by spring 24 to render valve 17 inoperative. The turbocharger can be run up to half speed, prior to starting, by turning cocks 28, 11, to direct air from compressor 10 through a nozzle 37 of the turbine. An air cooler 12 may be connected in the delivery line of compressor 10.

Filed: 1927-12-28
Abstract: 282,790. Ruth-Aldo Co., Inc., (Assignees of Barthelemy, H. L.). Dec, 28, 1926, [Convention date]. Cellulose esters and ethers, processes for making filaments and films from.-Filaments, films &c. formed from a solution in an organic solvent of a cellulose ester such as acetyl cellulose, formylcellulose or nitrocellulose, or of a cellulose ether, are coagulated by means of an aqueous solution which contains an emulsifying- agent such as ammonium or alkali metal salt of one or more of the higher fatty acids, such as oleic, stearic, palmitic, and ricinoleic, or of the sulphonated fatty acids such as sulphopalmitic acid and sulphoricinoleic acid, or Twitchell's reagent, decoctions of panama wood or quillaya. egg yolk, caseinates of ammonia, alkalies or alkaline earths, gum tragacanth, and ternary mixtures of alkali carbonates, phosphates, borates &c., water, and a higher fatty acid. Improved results are obtained by the addition to the bath of the following substances which mix or emulsify therein :- (1) alcohols, such as ethyl and butyl alcohols, glycol, glycerine, and cyclohexanol; (2) hydrocarbons, such as decane, tridecane, hexadecane, toluene, xylene, tetrahydronaphthalene, decalin, terpenes, polyterpenes, and mineral oils; (3) fatty acids of high molecular weight, and their esters such as methyl oleate and stearate, and ethyl oleate; (4) emulsifiable animal and vegetable oils. By lowering the surface tension of the bath, the diffusion of the solvent therein is facilitated and the filaments are more easilv maintained separate, while at the same time the threads are more perfectly lubricated as compared with the known processes for spinning artificial silk and artificial wool. By a suitable arrangements of the apparatus, the solvent may be continuously recovered from the bath, which is then returned for re-use. In an example, a solution of acetyl nitrocellulose in acetone is extruded into a bath composed of an emulsion of a 50 per cent solution of ammonium oleate, neatsfoot oil, and heavy paraffin oil.

Abstract: 1404665 Gas turbine engine rotor blades; axial flow fans GENERAL ELECTRIC CO 27 July 1972 [1 Nov 1971] 35152/72 Headings F1C and F1T To reduce operating noise at the expense of efficiency a gas turbine engine includes a rotor stage in which at least a length of the leading edge of each blade thereof is deliberately manufactured substantially more blunt or with means to render it effectively more blunt than the profile corresponding to optimum operating efficiency of the engine regardless of noise considerations. In one arrangement a ducted fan blade 28", Fig. 5, has a longitudinal chamber 76 communicating with the leading edge through spaced passages 78. When noise reduction is required a valve (86), Fig. 4 (not shown), is opened to supply pressurized bleed air to a region (82) adjacent the fan rotor disc (30) and thence through passages (80) into chamber 76 from whence the air exits through passages 78 to effectively blunt the leading edge. Passages 78 may be replaced by an elongated slot. In a modification, Fig. 6, the leading edge 68' of fan blade 28"' is cut back, e.g. over its radially outer one-third, to provide surface 94 which is covered by a deformable member 88 to define chamber 96. The latter can be evacuated or pressurized to cause member 88 to respectively collapse or expand to increase the leading edge bluntness when noise reduction is required. In other arrangements, Figs. 2, 3 (not shown), the leading edge is merely more blunt over all or part of its length than the profile for optimum operating efficiency. The degree of blunting is specified.

Abstract: 734,400. Spray carburetters. SOLEX. Dec. 17, 1953 [Jan. 17, 1953]. No. 35183/53. Class 7(3). A carburetter which supplies a primary mixture which itself consists of fuel and emulsion air and which is then diluted in an additional quantity of secondary air comprises static means such that when the depression causing the flow of the primary mixture exceeds a predetermined value the emulsion air of this mixture is at least partially replaced by fuel. As shown the upper part of a fuel well 20 communicates by means of a passage 22 and at least one orifice 23 with an inlet 10 for emulsifying air. Thus during operation a depression is produced in the well and the fuel level therein rises. It is arranged that at a predetermined speed (e.g. 2000 r.p.m.) the fuel level reaches the lower end of the passage 22 and fuel with a little air is then drawn through the passage into the tube 12 thus enriching the mixture very considerably. The central tube 22 may be replaced by a lateral channel opening horizontally into the well 20. The orifice 21 may be omitted. The tube 12 has lateral orifices therein.
