Title: Chains for use as stenter chains and pins for use in such chain
IPC: D06C3/10
Filed: 1973-06-08
Abstract: 1432001 Tentering fabrics J S COUSEN 29 Aug 1974 [8 June 1973] 27356/73 Heading D1S A stenter chain comprises an elongated member defined by a coiled rod or wire 12 having spaced aligned stenter pins 16 projecting therefrom, the pins 16 being held in position by means located in the passage defined by the coils 14 of the member and held by these coils. Preferably, the coiled member is of helically wound spring steel wire and the chain is endless with the pins equally pitched throughout the length. There may be the same number of pins 16 as there are coils 14. In one embodiment, Figs. 1 and 2, each pin 16 is provided with an enlarged cylindrical head 18 and the pins 16 are readily removable from the coiled member by passing the heads 18 between the coils 14. The chains are guided by tubes 20 each having an axial slot 22 through which the pins 16 project. In a modification (not shown), the heads of the pins are part-spherical and have complementary adjacent faces, e.g. one convex and the other concave. In another embodiment (not shown), the pins are plain and are held in position on the coil by a rod of flexible plastics material into which the pins are hammered. For slitting of a loosely knitted tubular fabric, the pins of a pair of chains are engaged with the fabric adjacent the line along which cutting is to be effected and, as the fabric is cut, the chains are caused to diverge.

Title: Improvements in or relating to bridges for measuring electrical impedance
IPC: G01R17/00
Filed: 1936-10-09
Abstract: 483,023. Telephone transmission measurements; resistance and capacitance measurements ; variable condensers. STANDARD TELEPHONES & CABLES, Ltd., WEBB, R., ROUSE, F. R., and FOWLES, F. V. Oct. 9, 1936, No. 27470. [Class 37] An arrangement for measuring admittance unbalances between pairs of conductors comprises a wheatstone bridge network in which each arm consists of a resistance and a capacity in shunt, so arranged that the capacity in the four arms of the bridge is altered by substantially the same amount, this amount being simultaneously added to two opposite arms and subtracted from the other two opposite arms, and the resistance in each of the four arms is also altered by substantially the same amount in the same manner, being simultaneously added to two opposite arms and subtracted from the other two opposite arms. Each arm of the bridge circuit comprises a fixed resistance in series with a variable resistance, both being shunted by a variable condenser. The variable resistance comprises a potentiometer P1 connected between adjacent arms of the bridge, while the variable condenser comprises a differential air condenser C1 connected as, shown. The rotary contacts of the potentiometers are carried by a common shaft while the differential air condensers C1 are in the form of a double condenser, the movable vanes of each condenser being mounted on the same shaft and each set of vanes being held between collars, screwthreaded to engage the shaft. The arrangement is such that rotation of the shaft carrying the potentiometer contacts adjusts the contact at the upper potentiometer as seen in the Figure in one direction while that at the lower potentiometer moves in the opposite direction, and a similar arrangement is employed for the condenser shaft. By this means, equal variations are made in each bridge arm at each adjustment, those in opposite arms being of the same sign and opposite to that of the adjacent arms. The wires of the cable pairs, the admittance unbalance of which is to be measured, are connected to terminals A .. D, while other terminals AT .. DT are connected to the terminals A .. D by removable straps and serve for connection to the bridge of the input windings of transformers T1, T2. These transformers are used, when measuring for end admittance unbalance, for connecting a detector amplifier either to terminals A, B or C, D of the bridge, according to which of these pairs of terminals is connected to the cable pair considered as the disturbed circuit, the other transformer then being disconnected. The transformers are doubly screened, the inner screen of each being in two halves connected to the ends of the inner winding and the outer winding has three terminals which are changed according to the frequency. A differential air condenser C2 is provided to compensate for zero error and condensers C3, C4 are connected across the potentiometers, being of such value as to compensate for capacity unbalance errors introduced by the phase angle of currents in these resistances.

Multiple-way valves.-Relates to a hot-and-cold water arrangement, particularly for lavatories on railway vehicles, having a cold-water valve which is opened alone for cold-water supply, and a steam valve which is opened simultaneously with the cold-water valve for mixing therewith when hot water is required. In such an arrangement the two projecting adjacent valve stems 6 are each provided with a long operating- lever 9, 10, the free ends of the levers being each provided with a press-button 15. The steam-valve lever 10 is provided with a laterally extending plate 20 which overlaps the axis of the water valve and abuts on an idle hinged plate 17, 18.

Class 39 (1) The second anode 8, Fig. 1, is tilted as a whole relatively to the common axis of the cathode 2, modulator 3 and first anode 5, so that the electrostatic field between 5 and 8 has a transverse component acting on electrons and ions, a magnetic deflecting field opposing the electrostatic field being provided for separating the electrons and ions and trapping the ions. The magnetic field is produced by pole pieces 11 secured to flange 7 on opposite sides of the axis, and co-operating with an external permanent magnet (not shown). A further final anode (not shown) may be provided as a wall coating, and may be connected to second anode 8. The electric and magnetic deflecting fields are such that the electrons are undeviated and pass through aperture 10, also on the common axis, to the fluorescent screen, while the ions are collected by anode 8. An ion stop in the form of an apertured disc may be positioned inside and supported from anode 8. Aperture 10 may be centrally disposed in end wall 9 provided that it remains on axis x-x. The common axis of electrodes 2, 3, 5 can be tilted with respect to the tube axis x-x so that the beam is finally on the tube axis if the electric and magnetic deflecting fields are slightly out of balance. In another embodiment, Fig. 2, the first and second anodes 14, 15 are discs and second anode 15 is tilted. Disc 15 may have a tubular member similar to 8, Fig. 1, attached thereto, and disc 14 may have a flange as in Fig. 1. In all forms the gun electrodes are bonded together by ceramic rods to form a unitary structure.
