WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, Pennsylvania, U.S.A.-(Assignees of Schaelchlin, W. ; 169, Woodside Road, Wilkinsburg, Pennsylvania, U.S.A.) May 28, 1931, No. 15633. Convention date, June 16, 1930. [Class 38 (v).] In order to prevent the jarring of the contacts of an alter. nating-current electromagnetic switch by the chattering of the armature, the movable contact is mounted on a movable weight which is connected to the arma ture by a resilient member. As shown in the Figure, the movable contact 20 is secured on a blade spring 28 attached to a cylindrical weight 22 mounted on a horizontal pivot. The weight 22 is connected to a depending arm of the pivoted armature 12 by a spring 27 so that when the laminated portion of the armature is attracted within the A.C. solenoid 11 any vibrations of the armature due to the varying force acting thereon will not be transmitted to the contact member, and its contact with the co-operating fixed contact will be unimpaired. The spring support of the movable contact also ensures contact being maintained if the switch base is subjected to mechanical vibrations. The armature is returned after attraction by a spring 16 which may be adjusted to vary the current setting. In a modified form, (Figs. 1 and 2 (not shown), the movable contact is mounted on a rectangular weight pivoted about a vertical axis. The weight is chosen to have a natural frequency of vibration not coinciding with the frequency of the A.C. supply.

Title: Apparatus for measuring prospective earth fault currents of electrical installations
IPC: G01R27/18
Filed: 1947-06-19
Abstract: 628,667. Currents measuring. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., ORCHARD, F. C., and HOLROYD, S. MAXWELL-. June 19, 1947, No. 16230. [Class 37] The invention has for its object to measure the earth fault current of an installation that would occur if the insulation broke down so as to provide a fuse of the appropriate rating. To this end, an impulse is applied from 4, Fig. 1, through an impedance 5 to the earth lead, and a part or the whole of the voltage developed across 5 is applied to a device 11 which operates at a predetermined voltage level, and the voltage applied to 11 is adjusted, e.g. by a calibrated resistance 13, so that the device just operates ; the current through 13 is then determinable and the fuse rating can be obtained. The impulse is generated by closing contacts A and 3, thus energizing relay 8 to close contact 10 and energize relay 9 to open contact A a fraction of a second after contact 3 is closed. The device 11 comprises relay 12, 14 so that when relay 12 operates it actuates relay 14 to open its contacts and deenergize lamp 16. Single relays may replace the pair 8, 9 and 12, 14 and a neon lamp may be lit by the closing of the latter relay, Fig. 2 (not shown). The relays 12, 14 may be replaced by a neon lamp in shunt with the variable impedance 13 which is adjusted until the lamp ignites, Fig. 3 (not shown).

[Also in Division H1K] An electrical conductor comprises matted fibres of electroconductive material embedded in a supporting body of dielectric plastics material which fills all the spaces between the fibres but does not adhere to them. In a first example, metal wool is combed and embedded between two sheets of uncured silicone rubber which adhere to the fibres, the resulting structure being moulded and cured at an elevated temperature sufficient to melt the rubber and destroy its adhesion to the fibres. In a second example a mass of metal wool fibres is placed in a mould into which is poured the embedding agent mixed with a catalyst and a foaming agent, the mould is capped and the contents are cured. Alternatively the embedding agent may be placed in the mould before inserting the metal wool. In a third example, a mass of metal wool is kneaded into a quantity of silicone putty. The metal wool may be sprayed with, or dipped in, a non-adhesive release agent, e.g. silicone grease, wax, or soap to prevent the embedding material from adhering to the fibres. The embedding material may also be polyurethane, P.V.C., polyethylene, or putty. It is stated that the embedding material may be a thermosetting plastic. The embedded fibres may constitute a pressure sensitive resistor. It is stated that the resistance varies with the magnitude but not the direction or sign of the applied force. Other uses are stated to be antennas, transducers, amplifiers and variable capacitors.
