Title: Improvements in or relating to carburetters for internal-combustion engines
IPC: F02M69/18
Filed: 1942-06-22
Abstract: 560,196. Spray carburetters. BEDALE, P. W. June 22, 1942, No. 8548. [Class 7 (iii)] A carburetter is of the type in which liquid fuel is supplied by a pump 20 to chambers 12, 32 and through a metering orifice and a meteredfuel chamber 35 to a spray nozzle 37 in the combustion-air inlet of the engine, the admission of fuel to the chamber 12 being restricted by a valve 23 adjusted by a diaphragm 13, which is loaded by an engine-driven governor 14 and is subjected on its opposite faces to the pressures in the chambers 32, 35. The valve 23 is thus adjusted to keep the pressure difference between'the chambers proportional to the square of the engine speed. The total effective area of the orifice 33 is controlled by means responsive to atmospheric pressure amd to the charge pressure maintained in the induction pipe 50 by a supercharger 39, the area being maintained proportional to the "adjusted charge-pressure"; this is defined as the charge-pressure less 1 /nth of the atmospheric pressure, n being a constant approximately equal to the compression ratio of the engine. According to the invention, the pressure-responsive means is arranged so to vary the effective area of the metering orifice 33 that it is a function of the " adjusted chargepressure " so long as that pressure is below a predetermined value and is another function, higher in value, when the said pressure exceeds that value, so that the fuel-air mixture is enriched at high charge-pressures. As shown, pipes 31, 40 connect the chambers 12, 11 respectively to the chambers 32, 35, which communicate through a metering orifice constituted by a main jet 33 and an enrichment jet 34. The jet 33 is adjusted by a needle'41 having a parabolic tip and connected through a link 42 to evacuated capsules 43 and a capsule 143 open to the atmosphere, the capsules being enclosed in a chamber 48 connected to the induction pipe 50. A slot 44 in the link 42 is engaged by a pin on a lever 46 connected to a rod 51 between capsules 52, 53 ; the capsule 52 is gas-filled and connected to a sealed bulb 55 in the induetion pipe in order to respond to the temperature therein, while the capsule 53 is evacuated and sealed in order to balance the effect of changes of atmospheric pressure on the capsule 52. A needle valve 56 for the enrichment jet 34 has a tapered tip and is connected through a lever 57 pivoted at 58 to the capsule stack 43 so as to open the jet under high boost conditions. Fuel-collecting grooves 62, 64, 65 around the governor shaft, 16 and the needles 41, 56 are connected at 63 to the supercharger inlet 38. A relief valve 26 in the pump outlet 21 is connected to a diaphragm 27 subjected to the pressure in the chamber 12.

Patent GB-603841-A (GB)
Title: Twist setting artificial fibre yarn
IPC: D02G1/10
Filed: 1946-03-22
Abstract: A twisted yarn composed of staple fibres obtained from drawn or stretched filaments of a highly polymeric ester produced by heating one or more glycols of the series HO.(CH2)n.OH, where n is greater than 1 but not greater than 10, with terephthalic acid or an ester forming derivative thereof, is subjected to a twist-setting treatment which comprises a heat treatment at a temperature at least 5 DEG  C. higher than the temperature at which the filaments were drawn, or subsequently heated, whichever was the highest, but less, preferably at least 30 DEG  C. less than the melting point of the yarn, while maintaining the yarn under tension.  The polymer may be obtained from ethylene glycol or trimethylene, tetramethylene, hexamethylene, or decamethylene glycol, and terephthalic acid or an ester, acid halide, ammonium, or amine salt thereof.  Drawing of the filaments may take place at temperatures above 60 DEG  C.  Crimped continuous filaments may be used for conversion to staple fibres.  Yarns of heavier denier may be obtained by plying or cabling lighter weight yarns.  The yarns may be plied and cabled to give a sewing thread. The twist setting may be effected by passing the yarn into contact with a heated surface such as a hot metal roller, a heated metal pin, or a metal pin with a non-metallic covering, or it may be effected by passing the yarn through a heated inert liquid, or through a hot inert gas, or by infra-red rays.  The twisted yarn may be passed round a heated metal roll or set of rolls, and it may then be collected on a roll or set of rolls rotating at the same or slightly lower speed.  In the latter case a small amount of shrinkage takes place but unlimited shrinkage should be avoided and the yarn should be under tension until cooled to room temperature.  The treatment may be applied to highly twisted yarns which are to be used in the production of crepe fabrics or which are to be used as sewing threads.  Twist-setting may be effected on the travelling yarn or while it is in package form. The treatment may be carried out on yarns containing a minor proportion of other fibres, e.g. cotton, wool, or rayon staple fibres.  If such yarns are allowed to relax during twist-setting, fancy effects may be obtained due to uneven shrinkage of the constituent fibres.  Specification 603,840 is referred to.

Abstract: 666,424. Gear-grinding. SYKES, Ltd., W. E. March 23, 1950 [April 7, 1949], No. 9480/49. Class 83 (iii). [Also in Group XXIII] A gear-grinding machine for generating spur teeth comprises a grinding-wheel 31 of rack tooth form, and means, including a slide 2, for rolling the work-piece 16 transversely to a relative reciprocatory movement between the work and the wheel, the relative reciprocation being in a direction inclined to the work axis so that a conical or non-cylindrical gear or cutter is produced. A conical blank 16 is mounted on a spindle 17 which is indexed by manual means 23 by or by a counter or other mechanism. The spindle 17 is journalled in a sleeve 18 which carries a drum 26 co-operating with adjustablymounted tapes and is itself journalled in the slide 2. The slide is reciprocated by a crank 6 driven by a variable-speed motor 15 or through change-speed gearing. The grinding-wheel 31, which may work on one or both sides of a toothspace, is belt-driven by a motor 34 and is reciprocated on guideways 36 by a crank 51 driven by a motor 45. The guideways 36 are angularly adjustable on a table 41 by means of a bolt 44. The table 41 is angularly-adjustable on a slide 55 which can be adjusted vertically by screw means 63 rotated manually by wormgear 69. The table is guided by means 58, 59 and is lowered at each end of the reciprocations of the slide 3 by a cam 72 also driven by the motor 15. Conical or cylindrical gears are produced according to the setting of the guideways 36, and straight or helical gears according to the setting of the table 41. Alternatively, the workslide may be inclined instead of the slide carrying the grinding-wheel, the work may be reciprocated instead of the wheel, or the reciprocations may be effected hydraulically.
