Title: Improvements in or relating to apparatus for projecting an image of a body on a screen
Inventor: ANNETT ALBERT EDWARD
IPC: G02B21/00
Filed: 1948-01-28
Abstract: 646,508. Optical gauging apparatus. BRISTOL AEROPLANE CO., Ltd. Jan. 28, 1948, No. 2610. [Class 106 (ii)] [Also in Group XX] Apparatus for projecting the outline (seen in section) of a body 5 on to a screen, comprises two light sources 7 each provided with a lens 10 in a mount 12, and shutter mechanism 11 which direct two narrow beams of light on to opposite sides of the body 5. Light reflected from each side of the body is reflected by mirrors 17 into a lens 16 mounted in one side of a hood 15. Light rays leaving the lens 16 are projected on to mirrors 18 and thence on to a screen 14, where an enlarged image of that part of the object 5 which has been illuminated appears. By suitable adjustment the two images join together so as accurately to reproduce the complete section of the body on a plane containing the light beams, i.e. on the plane xx of Fig. 4. The housing 15 has an aperture to receive a slide having the correct shape of the section for comparison with the body being gauged. In order to gauge the body 5 at three positions, e.g. the tip, middle and root of the turbine blade shown, the blade is mounted in a carrier 13, Fig. 3, which is intermittently reciprocated by a Geneva mechanism 22, 23, so that the blade is intermittently reciprocated along the axis of the blade. A suitable drive mechanism is provided whereby the shutters 11 associated with each light source are driven in synchronism with the Geneva mechanism so that illumination occurs only when the blade is stationary. The drive mechanism to the blade and shutter is designed to ensure that each of the three stations are illuminated at least 16 times a second to avoid flicker. Thus there is formed on the screen at the same time three continuous images for comparison with a master image. The master shape is preferably fully adjustable both angularly and linearly and such adjustments may be made by verniers,

Title: Textile crimping
IPC: D02G1/00
Filed: 1966-01-21
Abstract: 1,131,420. Crimping fibrous materials. INTERNATIONAL WOOL DEVELOP MENT CO., PTY Ltd. 21 Jan., 1966 [21 Jan., 1965], No. 2805/66. Headings DID, D1F, D1N and D1S. Strands of animal, vegetable or synthetic textile materials -for example spun or multifilament yarn, single or plied yarn, roving, sliver,. top, tow, carded webs, or open weave fabrics, of wool, nylon polyester, or acrylic fibres - are crimped by advancing the strand while confining it against free lateral motion at two closely spaced locations along the direction of advance, the strand being freely suspended between the two locations, and continuously moving the strand as it advances through at least one of the locations to and fro transversely so that the lateral position ol the strand as it reaches the second location is caused to move to and fro transversely thus causing the strand to be flexed into a crimped configuration. The first location, which is preferably moved transversely, is formed by an eyelet, a trough, a pair of rollers, or by a pait of conveyor belts, or by a pair of plates downstream of a pair of feed rollers and having at the downstream, end serrations or a pair of small diameter rolls. The second location which additionally or alternatively may be moved transversely is formed by a pair of rollers or conveyor belts. In examples the rollers at the first locations are reciprocated along a straight line by a crank or along an arcuate path, or moved along a circular path or along a saddle-shaped path. The conveyor belts of the second location may pass through a steam chamber to set the crimped strand, and/or the rolls at the second, and also perhaps the first, location may be heated by water, or steam, or electrically. A setting agent-for example sodium bisulphate, sodium thioglycollate, ethanolamine or monethanolamine-may be used for a strand of wool. In specific examples a woollen sliver was wetted or steamed before the first location, or wetted before or after the second location. The two locations may be horizontally or vertically spaced apart and the strand speed at the second location may be the same as, or fastel or slower than, the strand speed at the first location.

[Class 80 (ii)] A friction facing is attached to tongues struck from a clutch disc and is urged away from the disc by separate cushion members. As shown in Figs. 1 and 4, each tongue 5, to which one facing 10 is secured by a rivet 9, is formed between a pair of openings 3, 4 in the disc 1, which is secured to a splined hub 2. The other facing 8 is secured to the disc 1 by rivets 11 arranged between adjacent pairs of openings. Cushion members 12 mounted in the openings each comprise side portions 13, 14, curved in one direction and bearing with their ends against the facing 8, and a middle portion 15 curved in the opposite direction and bearing with its ends against the facing 10. The axial separation of the facings is limited by rivets 18. In a modification, each cushion member is in the form of a rectangular plate, adjacent plates being oppositely curved. In another modification shown in Fig. 11, each opening receives a pair of oppositely-curved plates 23, 24, arranged side-by-side, the tongues 25 being formed by U-shaped slots between each pair of openings. The plate 24, which bears with its ends against the facing 10, has a lug 22 engaging a notch 21 in the disc so as to retain the plate within the opening. Alternatively, each opening may receive a pair of oppositely-curved plates arranged back-toback, and riveted at the middle. As shown in Fig. 15, wherein cushion plates 27, 28 in adjacent openings in the disc 1 are oppositely curved, a tongue 29 or 31 is formed adjacent each opening by an L-shaped slot 30 or 32, alternate tongues being bent in opposite directions and the facing 10 being riveted to the tongues 29 while the facing 8 is riveted to the tongues 31. In the form shown in Fig. 20, the facings are riveted to alternate tongues 40, 41, and a number of circular openings 35 formed in the disc each receive a star-shaped plate 36, of which some arms are curved in one direction, others are plane, while others are curved in the other direction. In a modification of this form, the circular openings are replaced by circumferential rectangular openings receiving oppositelycurved blade springs. In the form shown in Fig. 28, the disc has radially-extending tongues 52 with enlarged heads 54, the facings are riveted to alternate tongues, and cushion plates 57, curved alternately in opposite directions, are held in place between the facings by the heads 54.

Title: Engine liquid fuel supply system
Inventor: JUBB ALBERT
IPC: F02C7/236
Filed: 1957-01-28
Abstract: 852,290. Gas turbine engines. ROLLSROYCE Ltd. Jan. 28, 1958 [Jan. 28, 1957], No. 3043/57. Class 110 (3). A fuel system for a continuous combustion gas turbine engine comprises primary and secondary fuel injectors, a main pump with control means metering the total fuel delivery to the injectors, through a main fuel line, branch fuel lines leading from the main fuel line to the primary and secondary fuel injectors respectively and a pressurizing arrangement, including a pump mechanically driven from the engine, in the branch line leading to the primary injector or injectors to ensure adequate pressure for atomization at all total fuel flows. Fuel is supplied to the combustion equipment 41 from a tank 9 by a fuel pump 10. The fuel is heated in an oil cooler 13 and then passed to the control and metering mechanism 14. The fuel pump may be driven by the engine or by an air turbine 8. The fuel dividing system comprises branch lines 17a, 17b leading to a manifold 46 for the primary fuel injectors 15 and to a manifold 47,for the secondary injectors 16. The branch line 17a contains an auxiliary engine-driven pump 18. A relief valve 22 in a by-pass 21 limits the delivery pressure of the pump 18. A fuel recirculating by-pass conduit 23 is also provided around the pump 18. The branch line 17b has a non-return valve 24 and a shut-off cock 25 which is coupled with a shut-off cock 19 in the line 17a. At low fuel flows the suction effect of pump 18 prevents the pressure in the pipe 12 from exceeding that necessary to open the valve 24 so that the whole of the fuel is delivered to the primary injectors 15. As the fuel flow increases, the delivery pressure of the pump 18 increases until the relief valve 22 opens. Any further increase in total fuel flow increases the pressure in the pipe 12 so that the valve 24 opens and allows fuel to flow to the secondary injectors 16. Under some conditions of operation, e.g. at high altitude, the total engine fuel requirements may be so low that cavitation will tend to occur in the pump 18. When cavitation tends to occur there is no flow in branch line 17b so that combustion chamber pressure acts on one side of the land 28a and displaces the piston valve 28 to the right against the action of the inlet pressure of the pump 18 plus the load of the spring 32 (or less the load of the spring when the spring is in chamber 29) until the chamber 30 opens the conduit 23. The pressures in the chambers 30, 31 are balanced by a passage 34. A filter may be incorporated in the line 17a.
