Abstract: 1,141,042. Cable markers. HELLERMANN ELECTRIC Ltd. 28 Jan., 1966 [16 March, 1965], No. 11099/65. Divided out of 1,141,041. Heading B8F. [Also in Division H2] In the method of compressing or crimping an insulating sleeve on to an electric cable terminal and/or joint, wherein the insulating sleeve is made of a plastics material and is cable of endurably gripping the cable by virtue of a property of the plastics material of being able to accept enduring deformation without substantial recovery at normal ambient temperatures, and wherein a sleeve is detached from a chain of insulating sleeves detachably attached together and temporary pressure alone or pressure and heat is applied to compress or crimp the sleeve around the terminal or joint, e.g. by cold-crimping, a reference mark may be applied to the sleeve to mark the cable. The plastics material may be a semi-rigid form of P.V.C. and the chain may be made flexible by part circumferential cuts between adjacent sleeves. A sleeve-applying machine loaded with a chain of sleeves may be used to feed the sleeves on to the cable and the crimping or compressing may take place before or simultaneously with the detaching. The machine may also apply the reference mark to the sleeve. The sleeve may be crimped around a ferrule, which is already present to crimp a terminal to the cable, and a free end portion of the sleeve may be left uncrimped.

Abstract: 1,197,696. Matrix core store. SIEMENS A.G. 8 March, 1968 [10 March, 1967], No. 11360/68. Heading G4C. [Also in Division H3] A capacitor is connected to a constant current supply to increase the initial voltage applied to a core storage matrix line and a switch is connected to discharge the capacitor as a result of the cessation of the line current. When switch 2 is made, a constant current device 1 is connected to a supply U2 in series with a load 3 and a discharged capacitor 12. As the capacitor changes to voltage applied to the load decreases until it is caught by diode 7 at a voltage U1. The load current through diode 13 holds a transistor 8 off but when the switch 2 is opened the transistor is rendered conductive by the discharge current of the capacitor and the latter quickly discharges. In Fig. 3 (not shown), the circuit is used to provide drive current to a core storage matrix line. The constant current device is a transistor and address signals select the line to be driven and the direction of the current. Two circuits according to the invention are provided and these are used alternately for read and write

Title: Improvements in friction clutches
IPC: F16D25/0635
Filed: 1919-05-09
Abstract: 137,220. Stansfield, R. May 9, 1919. Clutches, friction.-In hydraulically-operated plate and cone clutches, a continuous flow of liquid takes place between the frictional surfaces during the engaging movement of the clutch parts. Liquid is supplied by a pump through a channel F to the outer sides of plates C turning with a casing A secured on the driven shaft B and presses them into engagement. with a. central disk D on the driving-shaft E. The liquid escapes past the friction surfaces and enters a return channel G until full engagement takes place, when the flow ceases. To disengage the clutch, the direction of flow is reversed, the fluid entering by the channel G and returning by the channel F. Light engaging-springs P may be used, in which case a continuous disengaging-flow is required while the parts are running free. A double-acting cone clutch also is described, the liquid being supplied through one shaft to the space between the central cones, which are pressed apart for engagement, the liquid escaping past the clutch surfaces and passing away through the other shaft. An automatic release valve is provided on the delivery pipe from the pump.
