Abstract: 1517364 Measuring capacitance UNITED KINGDOM ATOMIC ENERGY AUTHORITY 2 Sept 1976 [17 Sept 1975 16 Oct 19751 38191/75 Heading G1U The capacitative measurement system of Specification 1340703 is modified in that the capacitance capacitative transducer is compared to a fixed reference capacitor, instead of a comparison between the two variable capacitors of the earlier transducer. Preferably, the transducer retains the two variable capacitances these being connected in parallel in the unknown arm of the bridge network. The transducer may be as disclosed in the earlier patent, or two wires in a glass tube secured to the bottom of a stainless steel tube for liquid level measurement Fig. 4 (not shown). For measuring the height of the mercury column in a thermometer, the wires lie along opposite sides of the thermometer tube in a space enclosed by a PTFE sleeve Fig. 5 (not shown). In a further transducer, the capacitance is formed between an earthed body and a screened wire probe Fig. 7 (not shown) for thickness measurements. As illustrated in Fig. 6 (not shown), the voltage applied to the variable capacitance arm may be varied in accordance with the measurement system output, to keep the charge on the capacitor constant thereby producing a linear relationship between the voltage and the plate spacing of the capacitor.

Abstract: 968,513. Fuel-injection pumps. SOC. ANON. POUR L'EXPLOITATION DES PROC•DES CHIMIQUES ET PHYSIQUES. Nov. 2, 1961 [Nov. 7, 1960], No. 39213/61. Heading F1A. In a self-regulating, cam-actuated fuel injection pump having a reciprocable and rotatable piston 2 supplied by a feed pump via a port 4 and distributing fuel to injectors via ports 5, the period of injection is controlled in relation to engine speed by a shuttle valve 7 controlling a by-pass 6. Shuttle 7 is moved upwardly by liquid pressure from a piston 10 via a channel 13 during the pump delivery stroke and is braked in its return movement under spring 15 by an adjustable throttle 18-in a passage 16, channel 13 having been closed by rotation of piston 10 moving a groove 20 out of register. The arrangement is such that for increased engine speed, shuttle 7 opens by-pass 6 earlier in the delivery stroke and thereby reduces the pump output. Cam 3 has a profile such that the piston assembly is axially stationary for a period at its upper and lower dead centres, during which the opening and closing of channels 12 and 13 with grooves 20 take place. The timing is such that channels 12 and 13 do not communicate with cylinder 11 at the same time. Rotation of pistons 2, 10 is effected through gears 32, 33 and a toothed member 30. In an alternative embodiment, grooves in piston 2 control the channel 13 which in this case opens into the lower end of cylinder 1. Specifications 861,754 and 904,518 are referred to.

Abstract: 1,219,687. Resin/filament wouni containers. RECHERCHES ET APPLICATIONS DES PLASTIQUES DANS L'INDUSTRIE ET LE BATIMENT. 16 Aug., 1968 [16 Aug., 1967], No. 39309/68. Heading B5A. [Also in Division B8] A tank of reinforced plastics material is made by constructing a collapsible shell to act as a mandrel, wrapping a first band of fabric impregnated with synthetic resin around the mandrel, wrapping a second band of fabric impregnated with resin over the first band so that it is displaced upwardly thereto; allowing the impregnated fabrics to harden, reducing the cross-section of the mandrel; raising the shell of hardened fabric, returning the mandrel to its original cross-sectional width, winding on to the mandrel a further first band of impregnated fabric adjacent to and below said first band, winding a further second band of impregnated fabric over said first and further first bands to cover the junction therebetween; allowing the impregnated fabrics to harden, reducing the cross-section of the mandrel; raising the shell of the hardened fabric; and so on until the desired height of the container is obtained. In Fig. 1 a tractor 5 tows a truck 4 around a cylindrical mandrel having a runway 27, the truck 4 having a wheel that engages this runway. The truck 4 carries a roll of fabric 31 that is fed through a tray to an inclined roller 29 from which the fabric 31 is wrapped around the mandrel, the tray being supplied with a mixture of liquids from two vats 6 and 7, for example an accelerated resin from vat 6 and a catalysed resin from vat 7. The truck also carries a roll 41 of fabric, for example glass fibre, that is wound on top of the first layer from the roll 31. The truck may be provided with a compressor (not shown) and a spray-gun for the projection of additional resin on to the fabric 41. The mandrel may have a domed top, some of the sectors of which are initially absent so that poles 2 can extend therethrough, these poles 2 each having lifting means coupled to the mandrel. The mandrel is in sections, Fig. 6 (not shown) that can be taken apart to reduce its cross-sectional area whilst the lifting means is being used. When the desired height of tank has been made the mandrel is dismantled and removed, the poles 2 are withdrawn, and the missing elements of the domed top fitted and secured in place. The bottom of the tank is then made in any known manner, for example by depositing layers of resin impregnated fabric on the slab supporting the tank.

Abstract: 945,574. Rolling tubes. BLAW-KNOX CO. Nov. 3, 1961 [Dec. 7, 1960], No. 39418/61. Heading B3M. A mandrel support for use in the rolling of seamless tubes of different diameters, comprises at least three rollers mounted coaxially with the pass line on arms which are moved so that the rollers are always equidistant from the pass line. As shown, three arms 42, 43, and 44, carrying rollers 32, 33 and 34, and pivotally mounted on shafts 45, 56 and 66 to a frame 31, are interconnected by links 59 and 75 such that operation of fluid pressure cylinders 52 and 72 moves the rollers inwardly to contact a mandrel 5. As the rolled tube 6 approaches the support, the cylinder 52 moves the rollers outwardly, to support the tube, and finally cylinder 72 raises roller 34 clear of the tube, by means of a sliding connection between a lever 68 and the link 75 so that arms 91 on a shaft 92 (Fig. 1) can lift and eject the rolled tube. Before rolling begins the mandrel is supported by rollers 17 which are subsequently moved clear of the mandrel while it is supported by the rollers 32, 33 and 34, by means of levers 13 connected to a longitudinally movable shaft 21. Stops 81, which are adjusted before rolling for the diameter of the tube to be rolled, determine the extent to which the rollers are moved outwardly. The tube 6 is formed from a rod 1 which is pierced as it is rolled between skew rolls 2 and 3.
