Title: An improved method for the volumetric computation of low outputs of liquids, and a meter for effecting the same
IPC: G01F15/02
Filed: 1950-12-22
Abstract: 696,236. Counting-apparatus. SEMISA SOC. ANON. Dec. 22, 1950 [Dec. 27, 1949], No. 31299/50. Class 106 (i). [Also in Group XXIX] A method for measuring low flows of liquid by circulating a quantity of liquid which is very large in relation to that to be measured, metering this large flow, abstracting the quantity to be measured, metering the remainder and finding the difference between the first and second meter readings, the relative areas of the two measuring meters being rendered identical by by-passing a very small part of the liquid to be measured around the meters. In one form of apparatus for carrying out the above method, Fig. 1, applied to the carburation system of a motor car, in which the fuel from the tank is pumped by a pump 2 and passes through the first meter 3, the required amount of fuel is applied to the carburetter at 7 and the remainder passed through the meter 8 and back to the tank 1. The difference between the readings of the meter 3, recorded on an indicating device 6, and of meter 8, recorded on an indicating device 11, is found by a differential device and shown on an indicator 12. The meters are bypassed by pipes 13, 15 fitted with regulating needle valves 14, 16 by which the relative errors in the meters are equalized and the total error thus reduced. In two embodiments described, the meters which are of the rotary type drive, through an ordinary type differential, a shaft connected to a ratchet-operated totalizator of known type. In another form, Fig. 6, one meter shaft 62 drives, through gearing 64, 66, a shaft 68 carrying a spring-loaded carbon brush 71 which moves over an insulating cylinder 75 mounted on a gear-wheel 67 driven from the meter 61. The cylinder carries contact pieces 73 which are electrically connected to the conducting shaft 69. The make-and-break circuit between shafts 68, 69 is used to operate a totalizer or rate-of-consumption meter.

Filed: 1973-07-05
Abstract: 1466565 Winding layouts NATIONAL RESEARCH DEVELOPMENT CORP 22 May 1974 [5 July 1973] 31974/73 Heading H2A A three-phase machine has three star-connected phase windings on a stator having N slots, where N is not a multiple of three, wherein two windings have an equal number of coils different to the third phase and the coil distribution is such that the negative-sequence components are substantially zero. In a four pole, 32-slot motor or generator, the three phases have 12, 10 and 10 coils respectively. The coils are wound in the groups shown such that the phases B and C effectively lead and lag phase A by 120‹ + α. The angle α is determined from unbalanced current theory to reduce the negative sequence component to zero. Since the phases are star-connected, the zero-sequence component can be ignored, leaving only the balanced positivesequence component. Thus a three-phase machine may be wound on stator stampings which may primarily be designed for small single phase machines.

Abstract: 1433603 Self-processing cameras EASTMAN KODAK CO 5 July 1973 [5 July 1972] 32056/73 Heading G2A In a camera for exposing and initiating the processing of a self-processing film unit 10 by passing it between pressure rollers 98, 100, a deflecting means 124 can be moved into or retracted from the path of the unit as it emerges from the rollers. As shown, the film units Fig. 2 (not shown) each consist of a photo-sensitive sheet (18) and a transparent process sheet (20) permanently attached together along their lateral and trailing edges. These are attached to a carrier sheet (16) supporting the container (14) holding the processing material, the sheet having at its leading end a transverse stiffening bar 50. The film unit is moved, after exposure, by slide plates 132 normally retracted by springs 136. Plates 132 are slidably supported adjacent stationary guide members 106 by means of shafts 128 which extend through slots 134 in the plates, the shafts 128 carrying the deflecting means 124. Deflecting means 124 consists of two arms, connected by a cross bar 130, whose forward ends are shaped as fingers 126 which initially extend into annular grooves 122 in pressure roller 100. Plates 132 have pawl teeth 142 which enter into slots (54) in the film unit adjacent the stiffening bar. Roller 98, which acts as the drive roller, has at each end of its shaft 102 a driving disc 150 carrying a pin 152. As roller 98 rotates, pins 152 engage against slide plates 132 and drive them forward to the Fig. 8 (not shown) position. The pawl teeth 142 thus engage and move forward the film unit into the nip of the rollers. The fingers 126 are urged into the grooves 122 by a weak spring 146, one end of which is received in a slot 148 in slide member 132. As the bar 50 emerges from the nip of the rollers it engages under the fingers 126, and these are urged downwards towards grooves 120 in roller 98 under the action of spring 146 as this is flexed by the movement of slides 132. Thus bar 50 is guided rearwardly by guide faces 108 on guide members 106, and carrier 16, now waste material, passes round roller 98 into the rearward part of the casing of the film pack 70. As the leading edge of the image-recording section 18, 20 emerges from the roller nip, however, it is guided by the forward edges 176 of the deflecting means 124 so that it is separated from the carrier sheet 16 and is guided through an exit slot 180 in the end-wall of the camera.

Abstract: 1,223,259. Spinning and finishing yarn. NELSONS SILK Ltd. 12 July, 1968 [13 July, 1967], No. 32229/67. Heading D1F. A running multifilament bundle is formed into yarn by moving it laterally into and out of contact with a lateral interlacing, and perhaps heating, jet of fluid e.g. air, nitrogen, carbon dioxide, steam or water, the frequency and direction of the contact of the filaments and jet being such as to cause continuous interlacing of the yarn and the tension of the bundle being such as to prevent formation of crunodal loops in the filaments, although the tension may be abruptly intermittently relaxed in synchronism with the bundle making contact with the jet. In a converted ring-or capspinning machine, a running bundle, passing through a combined tubular guide and jet apparatus (located on the axis of a yarncollecting bobbin) to a ring-traveller or lower edge of a cap, generates a balloon which is deflected, say once in each cycle, by a projecting edge of a deflector plate inwardly of the balloon and released when a segment thereof is in the path of the jet.
