Abstract: 296,092. Leslie, P. R. Aug. 26, 1927, [Convention date]. Tabular calculators; multiplying - apparatus. -A device for ascertaining the cost of a job in relation to a particular operative comprises a scale with variable graduations adapted to be set according to any particular rate of payment, means which is moved, or moves, to an extent proportional to the elapsed time, and means for recording the costs determined by the relative movement and the job or other identification numbers. In the form shown in Figs. 1, 2, and 4, a spiral scale 2 is provided on a hollow core 3 inside a slotted sleeve 1 and the core is provided with an internally threaded collar 6 engaging a threaded screw 7 on a spring-controlled plunger slidable on feathers in the end caps 9 of the sleeve 1. The plunger carries a finger piece 12 and its longitudinal position determines the part of the scale which is visible. This position is limited by setscrews 13 adjusted in accordance with the rate of pay the screws passing through threaded apertures in a cross bax 14 while the sleeve 1 is mounted for tranverse movement by the provision of rollers 25 riding on rails 26. A cursor 15, adapted to slide on the sleeve 1, has a pointer 16 co-operating with scale 2 and an off-set pointer 17 co-operating, with a time chart 18. The chart is constituted by a paper-strip led from a supply roll 19 around guide rollers 22, 23 and driving roller 24, to a spring-controlled spool 20. The roller 24 may be rotated automatically by clockwork through a spindle 28A or manually by gearing 33, 34, associated with a handle 35 and time-indicating dial 32. The time of completion of one job and the start of the next is marked by a horizontal line drawn across the operatives' column. At the completion of the second job the cursor 15 is moved to the new position of the line whereupon the pointer 16 indicates the wages due. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a form shown in Figs. 6, and 7 (Cancelled) having counting- mechanism driven in accordance with the variable rates of pay for use in factories where the number of operatives is relatively large in relation to the number of rates of pay and in which job cards are employed. The counting- mechanisms 55 are actuated through friction wheels 51, 52 rotated by gearing 49, 50 from a shaft 43. This shaft may be operated manually by a handle 46 in accordance with the elapsed time or automatically through gearing 48 from a clock-operated shaft 47. The shaft actuates an indicating pointer 44 movable over a dial which may be graduated in working hours only. The friction wheels 51 which are carried on spring controlled arms 57, can readily be replaced by others of different diameters according to the rate of pay. The friction wheels may be replaced by other change speed mechanism such as discs or coned pulleys and belts. This subject-matter does not appear in the Specification as accepted.

Filed: 1960-08-30
Abstract: 906,417. Laminates. UNITED STATES RUBBER CO. Aug. 30, 1960 [Sept. 17, 1959], No. 29822/60. Drawings to Specification. Class 140. [Also in Group IX] An armoured fabric capable of being joined to unarmoured or similar armoured fabrics to form shaped articles of projectile resistant clothing comprises two textile fabrics joined together, e.g. by stitching, along parallel rows to form a series of adjacent pockets, each of which contains a projectile-resistant plate, e.g. of steel, which is held firmly in place by shrunk thermoplastic yarns contained in at least one of the fabrics. The armoured fabric may be made by using a first and second fabric, at least one of which has heat-shrinkable yarns, or which both have heat-shrinkable yarns of different shrinkage capacities, e.g. polyethylene, or a copolymer of polyvinylidene chloride and polyvinyl chloride, inserting projectile-resistant plates in the pockets formed by the parallel joins, and heating, e.g. in water, said fabrics to shrink the yarns into tight engagement with the said plate. The shrinking may be carried out by passing the armoured fabric into hot water at an angle to the surface such that the unequal shrinkage properties causes one fabric to shrink more than the other, thus pulling an edge of one plate over the edge of the adjacent plate in an overlapping shingle effect. Layers of the projectile-resistant fabric may be joined together or may be attached to a harness of narrow webbing. Drawing-in draft information on the weaving of the fabric is given in the Specification.

Title: Improvements in centrifugal pumps
IPC: F04D7/04
Filed: 1929-10-02
Abstract: 331,150. Ash Co. (London), Ltd., (Allen, F. B.). Oct. 2, 1929. Disc-supported-blade pumps; leakage-preventing devices.-In a disc-supported blade pump the injurious pumping fluid is prevented from reaching the relatively movable parts of the pump by a flow of non-injurious fluid from two side chambers 36, 38 into a main chamber 37. The flow is obtained by an auxiliary blade 29 which is longer than the main blade 28, and by making the outlet opening of the main chamber larger in relation to the blade 28 than the openings leading from the chambers 36, 38 into the chamber 37, are in relation to the blade 29. In the horizontal pump shown in Fig. 1 non-injurious fluid from a pipe 43 passes through the chamber 36 and then divides; some passing through the narrow clearance 39 between the blade disc 27 and an adjustable ring 33, and into the main chamber 37; some passing through the pipe 41 to the chamber 38, through the clearance 40 and thence into the chamber 37, and some gassing along the pipe 42, through the rifled bearing 16 back to the chamber 36. If the pressure in chamber 36 exceeds that in 38, the impeller moves axially, enlarging the clearance 39 and closing the clearance 40 and a clearance 40a between an adjustable wear ring 45 and a raised part of the disc 30. In the vertical pump shown in Fig. 2, a pipe 57 brings non- injurious liquid into the housing 52 whence it passes through the pipe 58 which corresponds to the pipe 43 of Fig. 1. Around the inlet pipe 59 are arranged a number of nozzles 61 through which diluting liquid can be forced.

Title: Fuel controls for gas turbine power plants
Inventor: TORELL BRUCE NORRIS
Filed: 1957-09-26
Abstract: 824,467. Gas turbine plant. UNITED AIRCRAFT CORPORATION. Sept. 26, 1957, No. 30214/57. Class 110 (3). [Also in Group XXIX] Fuel is supplied to the nozzles 56 of a gasturbine engine by an engine-driven pump 26 via a metering valve 32, a conduit 52 and a manifold 54; the valve 32 consists of a fixed liner 38, with one or more inlet and outlet ports 36, 48, and an axially and rotatably movable cylinder 42 with one or more inlet and outlet ports 40, 46, the two sets of outlet ports 46, 48 being rectangular. The pressure drop across the valve 32 is held constant by means of a spring-loaded piston 60 controlling a by-pass 68 across the pump. Axial movement of the cylinder 42 is effected by a speed governor 76 driven by the engine compressor 14 whilst the governor datum is adjusted from the throttle lever 82 by a threedimensional cam 86 and a liner 90 that controls the loading of the governor speeder spring 94. The speed selection is modified by rotating the cam 86 by a rack 136 connected to a piston 130 supplied with fluid from pump 26 through a restriction 144, the piston position being determined by a hinged leak-off valve 120 controlled by an evacuated bellows 112 in a chamber 110 subjected to compressor inlet pressure; the piston 130 is loaded by a spring 128 the other end of which abuts a plate 126 connected to the lever 116 of the valve 120. The lever 116 is loaded by a spring 240 which tends to close valve 120 when the difference between the pressures in bellows 112 and chamber 110 is small so ensuring a sufficient force under all conditions for moving the piston 130. Rotation of the cylinder 42 is done through a rack 162 and a pinion operated by a servomotor 160, similar to that for rotating cam 86, which is responsive to compressor discharge pressure. The upper spindle 166 of the cylinder 42 has an abutment 172 which co-operates with stops 168, 170 that limit the opening of the metering valve 32. The position of stop 170 is controlled by a bellows 176, responsive to compressor inlet temperature, an axially movable shaft 178 connected thereto, and a crank 236. On shaft 178 is a pinion 210 and a three-dimensional cam 180, the pinion being engaged by a rack 198 actuated by a servomotor 196 similar to that for rotating cam 86 but sensitive to compressor speed through a governor 184; rotation and/or translation of cam 180 is transmitted by a liner 214 and a shaft 218 as an axial motion to another three-dimensional cam 220, the rotation of which is effected by another servomotor similar to that for rotating cam 86 but responsive to compressor inlet pressure. Cam 220 adjusts the stop 168 via a lever 230.
