Title: Improvements in and relating to load measuring means
Inventor: NEWBERRY CYRIL WILLIAM
IPC: G01L1/22
Filed: 1952-12-05
Abstract: 739,278. Load measuring gauge. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 5, 1954 [Dec. 5, 1952], No. 30986/52. Class 40 (1). A load measuring gauge comprises a hollow ring of elastic material through which the load is transmitted in a direction normal to the plane of the ring, having at least one resistance strain gauge fixed to the outer or inner periphery to respond to the circumferential strain. Circular section steel ring 11 has four strain gauges of equal resistance fixed on it, two 22 extending around almost the entire outer periphery and being connected in opposite arms of a bridge circuit, and the other two 21 extending around the inner periphery and connected in the remaining arms. Connection to the inner gauges, which have more limbs than the outer to compensate for their shorter length, is through diametral hole 24. Load is applied to the ring through a pair 12, 13 of steel plates with annular grooves into which the ring fits, the groove being sealed by cork packing ring 14 and rubber band 15. The plates are held together by nut and bolt 16, 17 bearing on resilient washers recessed into the plates. Balancing resistor 23 is also mounted on plate 13. The strain gauges which are of wire, e.g. of metals known under the Registered Trade Marks " Nichrome " or " Eureka," on paper bases are applied by means of phenol formaldehyde resin diluted with alcohol and are then covered with the undiluted resin, bound with tape and the whole then cured. The ring 11 may be of elliptical or lenticular cross-section with the major axis parallel to the load. The working range is proportionately increased by using a thin walled ring of material with a high ratio of elastic limit to elastic modulus, e.g. alloy steel or that known under the Registered Trade Mark K. " Monel " metal.

Title: Improvements in building construction
IPC: C04B32/00
Filed: 1924-12-29
Abstract: 239,765. Pope, H. E. Dec. 29, 1924. Casing and moulding in situ; building- materials, special.-Buildings are cast in situ from a slag of relatively low melting temperature by running the melted material into metal or other non-combustible moulds. The moulds may be water-jacketed to reduce the temperature quickly, but if a smooth face is required the mould may be heated prior to the casting. Broken brick, stone, or other matrix may be used and should the slag be of a higher specific gravity than the filling material, lighter granulated materials which will remain in the finished product as a mechanical mixture may be mixed with the slag, or readily volatile substances such as carbonate or sulphate of lime, and carbonate of ammonia, which give off or produce gases at moderate temperatures, may be placed in the ladle before the slag is run in. By this means the slag will contain bubbles and its specific gravity will be reduced. The moulds may be faced with sand or decorations to produce effects on finished surfaces. Metal reinforcement may be used'. The slag may be of such materials as to produce a body approximating to glass for use where windows and lights are required. A suitable slag would be 35 parts of ferrous oxide, 40 parts of sand, 15 parts of carbonate of lime, and 10 parts of carbonate of soda. The ferrous oxide may be replaced by ferric or manganic oxides or metallic silicates, or omitted where translucent effects are desired.

Abstract: 681,558. Making gloves. HAWORTH, A. K. Dec. 4, 1950 [Dec. 3, 1949], No. 31098/49. Class. 141. A method of forming a glove &c. having a fabric base coated or impregnated with a synthetic resin e.g. polyvinyl chloride, comprises placing the fabric base on a former and dipping it into the resin, then attaching it to a horizontal endless conveyer which slowly carries it over a draining trough then into a heated zone in which the temperature gradually rises from room temperature to curing temperature, this zone being heated by the residue heat from a second zone in which the glove is cured, the glove subsequently passing into the atmosphere to be cooled. As shown, the conveyer band A slowly passes round rollers B<SP>1</SP>, B<SP>2</SP> and has spaced projections a on which formers carrying the gloves can be mounted after dipping into polyvinyl chloride solution in a receptacle F. The draining trough E is of V-shape and is preferably connected to the. receptacle F. The heating chamber C is arranged above a portion of the conveyer and has a slot in the bottom to allow each projection a to enter the chamber and travel along inside it. The chamber is divided into three zones c<SP>1</SP>, c<SP>2</SP>, c<SP>3</SP>, the latter two being directly heated by means of gas supply pipes D and burners whilst the first zone has a gradually increasing temperature from bottom to top so that the glove is gradually brought up to the curing temperature. In the zone c<SP>3</SP> it is submitted to a higher temperature to give it a glossy finish. Instead of the gloves being previously dipped, the conveyer may be arranged to dip the fabric bases mounted on the formers into the receptacle containing the resin. The gloves may remain at room temperature during the draining period or it may be raised to about 85‹ F if a thinner coating is desired.

Title: Improvements in distributing or restoring devices for flat carrier members, such as the matrices of type line composing and casting machines
IPC: B41B11/18
Filed: 1931-11-11
Abstract: 382,086. Distributing matrices &c. ; addressing- machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London. -(Schweiz. Lokomotiv- & Maschinenfabrik; Winterthur, Switzerland.) Nov. 11, 1931, No. 31279. [Classes 100 (ii) and 100 (iii).] In distributing-mechanism for flat members, such as the matrices of type-bar-making machines, the matrices of type-line composing and printing machines, or the printing- plates of addressing-machines, a separating- device is employed, which, owing to its wedgelike construction, is adapted to separate the foremost member of a line from the remainder, and to deliver it to the distributer. In one form, a series of plate-like members 12, Fig. 1, which carry printing-types 11, is pressed by a pusher 8 against a separating device in the form of two pairs of levers 3, 4, Fig. 2, which project into a line channel 2 from opposite sides, and form an escapement mechanism. The levers are rocked in alternation by cams 5, 5a, so that, when the leading plate is released by the forward pair of levers, the remainder are held back by the rearward pair. The rearward levers are provided with bevelled portions which, when the levers are projected, push forward the leading plate away from the others, and deliver it to feed-screws 9, which convey it along a ribbed distributer bar 10. In a modification, the two pairs of levers are replaced by a single vertically moving pusher 3<1>, Fig. 5, having a tapered recess in its leading face, to engage and lift the foremost plate 12. The rear face of the pusher is bevelled, so as to push back the remaining plates, when the first is lifted. The plates are delivered by pins 21 on a conveyer chain 9 to a distributer bar 10. A spring-pressed slide 23 passes under, and supports, the lifted plate.

Title: Hydraulic motor drive
IPC: F03C1/06
Filed: 1971-07-05
Abstract: 1344325 Hydraulic reciprocating motors ABEX CORP 5 July 1971 [6 July 1970] 31472/71 Heading F1A The speed of a rotary output hydraulic motor, e.g. an axial piston motor for driving a Gatling gun, is controlled by a slide valve 29 controlling flow through the motor supply and discharge conduits 33, 34, the valve 29 being controlled manually by lever 59, or automatically by hydraulic pressure acting in valve chamber 48 against the bias of spring assembly 49, a governor 77-79 driven by the motor controlling the pressure in chamber 48 to maintain the motor speed constant. For starting, solenoid 65 operates valve 66 to connect chamber 48 to the supply via filter 68 and throttle 69. The pressure in chamber 48 moves valve 29 against springs 49 to open the supply and discharge passages 31, 33 and 32, 34. When the required speed is reached, as determined by the axial setting of a rod 75 carrying an outlet 72 controlled by governor 77-79 further increase in speed causes the governor to open outlet 72, causing a fall in pressure in chamber 48, so that springs 49 move valve 29 to reduce the supply to the motor. For stopping, solenoid 65 is de-energized causing valve 66 to connect chamber 48 to discharge connection 32, so that springs 49 move valve 29 to its closed position. The inlet connection through passages 31, 33 is closed before the discharge connection through passages 32, 34, so that as the motor decelerates, pressure builds up in passage 34 and acts through valve passage 55 on piston 56, thereby biasing valve 29 to open the discharge connection to control the rate of deceleration of the motor in two stages determined by springs 51, 53 of assembly 49. In the closed position of valve 29, inlet and outlet passages 33, 34 are inter-connected via passages 36, 37 and valve groove 43 to permit rotation of the motor by hand. In Fig.3 (not shown), the motor can be run at three selected speeds or in reverse, valve 29 being positioned under the control of a pilot valve (106) which controls the pressure differential in chambers (48), (94) at opposite ends of valve 29, valve (106) being controlled by a jet pipe (100) operated by an electric torque motor (99).

Abstract: 430,157. Gas - flow regulators. STEWART, J. G., Sigma Works, Spring Road, Letchworth, Hertfordshire. Nov. 14, 1933, No. 31712. [Class 135] A gas-flow regulator for securing a sufficiently constant flow at standard temperature and pressure for use in a gas calorimeter and wherein the gas after passing a pressure governor forms a column extending to an orifice through which the gas passes, has means for maintaining the pressure immediately adjacent to the gas outlet comprising an air inlet in the pipe leading from the outlet to a burner, the air entering at such a rate that the pressure opposing the flow of gas is equal to the air pressure at the governor plus the pressure due to the difference of level between the governor and the outlet irrespective of the variations in height of the burner and variations in suction effects produced at the burner itself. A casing 1 with a restricted air inlet 2 has a liquid seal 3 for a bell 4 on an arm 5 pivoted about a knife-edge 6. A counterweight 7 ensures that the bell balances a pressure equal to the difference in atmospheric pressure at the governor level and gas outlet level at standard temperature and pressure. The bell controls a valve 11 in the gas supply 13 by means of a projection 8 and lever 9. A pipe 14 forms a gas column leading to an orifice 17 through which gas passes to a chamber 18 connected to a burner 20 through another restricted passage 21. The chamber 18 is in communication with an air column enclosed by a pipe 23 extending from the governor casing 1, and a hole 22 for admission of air for maintaining the gas flow constant is formed in a part of the pipe 23 depending from the chamber 18. The orifice 21 may be omitted if the pipe leading to the burner offers sufficient resistance. Specification 197,159, [Class 135], is referred to.

Also associated with the winding 2 and the capacitor 4 is a series circuit constituted by a capacitor 14 and a further switching transistor 15 controlled by switching pulses B which have the same frequency as the pulses A but which are phase-displaced therefrom by an amount dependent upon the difference between the output voltage and a reference voltage. The arrangement is such that the capacitor 14 is switched into or out of the oscillating circuit 2, 4, in dependence upon output voltage variations, in such a manner that the output voltage UH is maintained constant, and the Specification describes this operation with reference to Fig. 2 (not shown). A suitable circuit 22 for providing the phase shifted pulses B is described with reference to Fig. 3 (not shown).
