IPC: F02B33/00
Filed: 1931-12-23
Abstract: 378,754. Hydraulic transmission of power. SINCLAIR, H., 6, The Crest, Surbiton Hill, Surrey. Dec. 23, 1931, No. 35611. Convention date, Jan. 10. [Class 69 (ii).] A blower for supplying air or mixture to the engine of aircraft is driven through a hydraulic coupling of the Fottinger type-such as described in Specification 378,726-wherein there is variable slip this being controlled automatically according to the working conditions of the engine. The impeller 13 is mounted on an extension 16 of the engine shaft and is driven through spur gear 17, 18, 22, 8 and the coupling 24 ; the core member 23 of the driven element of this coupling is formed with a collecting chamber 29 having exhaust passages 30 to allow flow of oil out of the coupling to a sump. The lubricating oil pump supplies oil through a bore 31 in the shaft on which the driving element of the coupling is mounted, passing into the coupling through ducts 32. The circulation of oil and thereby the amount of slip is controlled by adjusting the flow to the coupling ; the carburetter throttle 5 is interconnected with a valve 46 in the oil bore 31 so that at small throttle opening there is no oil flow and much slip in the coupling. A second valve 33 is connected to a bellows 36 loaded with an adjustable spring ; the bellows is contained in a chamber connected by a pipe 38 to the delivery side of the blower so that the flow of oil in the bore 31 depends on the pressure of the charge. In place of the valve 46 a valve may be placed in the pipe 38 and moved in correspondence with the throttle ; the blower works then only in sub-normal pressures. When used on compression ignition engines the valve 46 is interconnected with the fuel control. The control may be subject to the variations in temperature of the engine ; for this purpose the bellows contain a gas or volatile liquid and cooling water or lubricating oil is caused to flow through the annular chamber 50. In another arrangement the control may be directly due to barometric conditions. Three couplings may be arranged in parallel to drive the impeller, the flow of oil to the coupling chambers being controlled by one valve or set of valves. Couplings as described in Specifications 314,157 and 328,028, [both in Class 69 (ii), Hydraulic presses &c.], may be used. In place of the lubricating oil any other liquid circulating medium may be used.

Abstract: 1,014,765. Pin stenters. E. B. BATES. Sept. 9, 1963 (Sept. 21, 1962], No.35940/62. Heading D1S. In a stentering machine the pins or hooks which engage the margins of the fabric are formed on endless flexible metal bands e.g. of spring steel, which as shown have teeth formed on an edge thereof and pass about drums 13a, 13b diverging as they pass through channel shaped guides 15a, 156. The fabric F which before contacting the pins passes about rotating rods 43, 44 having oppositely directed threaded portions to uncurl the edges of the fabric, is brushed on to the stenter pins by freely rotating brushes 47a, 47b. Leaving this zone the bands are turned in a horizontal plane by suitably shaped channel guides 19a, 19b to further stretch the fabric and become disposed in the same plane as the fabric. The bands and fabric then pass through a heated calendering device 21 comprising two cylinder and blanket arrangements 22, 23 and 25,26. The fabric then passes over a cooler 31 and is lifted from the pins by ploughs 32 to be wound or folded. The bands return via guide rollers to the drums 13a, 13b. Devices 5Qa, 50b each having a pair of micro-switches operated by edge feelers, sense the position of the fabric as it enters the stenter and motors 64a,66b are operated to shift blocks 66a, 66b on which the drums 13a, 13b are mounted in a corrective manner. Rotating threaded rods are associated with each sensing device to ensure that the edges of the fabric remain uncurled. The guide guides l9a, l9b are mounted on an oppositely threaded rod 68 which may be rotated by a handle 69 so that the width to which the fabric is stretched may be adjusted. In a further embodiment the bands 11a, 11b have fabric gripping hooks pressed out from the sides thereof and in this case the fabric may be fed to the bands while they lie in an horizontal plane.

Abstract: 1,090,220. Making metallic webbing. FABRICAS LUCIA-ANTONIO BETERE S.A. Aug. 12, 1966 [Aug. 14, 1965], No. 36304/66. Heading B3E. [Also in Division D1] A method of continuously producing metallic webbing, from a continuous length of chain and from wire staples comprises stapling together selected individual pairs of links of the chain, each pair consisting of two links spaced apart along the length of the chain. Wire 1 is fed by rollers 3, moved apart once a revolution by cam means 4, and a length is cut therefrom when stationary by a knife 5 on a slide 6. The cut length is formed into a U-staple by pivoted bars 7 which, as the slide 6 moves down, bend the wire over a support 9, engagement of the bar 7 with a tapered guide 8 causing them to move, in addition, towards one another. The legs of the then formed staple extend through links 10 spaced apart along the length of a chain but brought side-by-side by passage of the chain helically over pulleys 14 on a pair of intermittently rotating shafts. The ends of the staple are bent over the support 9 to connect the links 10 by members 11 on a second slide, a member 13 completely closing the staple. The length of the webbing formed is determined by stopping the feed of wire, and thus staples, at intervals by ratchet means 16 which separates the feed rolls 3, so that a line of unconnected links extends across the width of the webbing. The width of the webbing formed is determined by stopping the wire feed for successive staples, by ratchet means 17, for a length of time corresponding to the passage of two webs in side-byside alignment.
