Title: Improvements in or relating to electric protective relays
IPC: F16L19/065
Filed: 1932-02-12
Abstract: 390,922. Protective cut-out arrangements ; induction relays. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Feb. 12, 1932, No. 4221. Convention date, Feb. 12, 1931. [Class 38 (v).] In a protective relay having a time-controlled operating contact, and a measuring adjustment contact which adjusts itself when a fault occurs, the adjustment contact is held initially in a position corresponding to a suitably selected fraction of its measuring range. An impedance measuring contact 4, Fig. 1, is held by a stop 7 against the action of a current coil 2 in a position representing a fraction of its measuring range. Upon fault a voltage coil 3 is energized, and the stop 7 released, so that tripping takes place in accordance with the impedance, when a time-controlled contact 5, simultaneously released, engages the contact 4 in its adjusted position. In Fig. 2 the contact 4 is held by a contact stop 8 so that on fault, if the impedance is below that corresponding to the initial setting, tripping is effected by an advance time-controlled contact 11 engaging a contact 12 connected with the contact 8. With faults beyond, the tripping is effected by the time-controlled contact 5 engaging the contact 4, as in Fig. 1. The initial position of the contact 5 may be adjusted. In Fig. 5 (not shown) a directional relay is associated with the impedance relay to allow tripping only with a certain direction of current flow. The invention is applicable to current-time, voltagetime, and double earth-short time relays. Fig. 6 shows the application to a voltage-time relay in which the initial position of the adjustment contact is determined by the current strength. A current coil 126 overcomes a voltage coil 120, so that a contact carrying arm 123, actuated by the voltage coil, is held by the current coil contact 124. With a fault within a certain distance tripping is effected by the engagement of a contact 132 with a time-controlled contact 131, but at greater distances the tripping is effected in accordance with the voltage by the engagement of a second contact on the arm 123 with a second timecontrolled contact.

Class 80 (2) .[Also in Group XXXII] In a universal joint a rubber bush 1, Fig. 1, which is bonded to a sleeve 2 has a metal ring 3 vulcanized into the rubber, so that when the bush is force-fitted into an outer tube 4 the rubber between the ring 3 and the tube 4 is under greater radial compression than the rest of the rubber. The end of the ring 3 which is embedded in the rubber may be turned out. wardly. To help retain the bush in position, slots or holes may be provided in the member 4. These apertures may be closed by a strap whilst the rubber bush is being inserted. Alternatively, the tube 4 may have inwardly directed indentations which increase the compression of the rubber bush. In a further embodiment, two rings 3, 9, Fig. 6, may be provided. The surfaces of the elevations 10, 11 may be lightly ground. Two rings may be vulcanized into the bush, the outer ring being longitudinally divided into two equal portions. The inner ring could also be divided and the outer ring could be divided into more than two parts. Fig. 9a shows a further embodiment in cross-section, the portion of rubber 14 may be omitted.

Abstract: 667,823. Power generating systems. MAR GUERRE, F. Feb. 21, 1950. No. 4380/50 Class 122 (iii). A high pressure boiler system comprises a boiler having a superheater and auxiliaries which include combustion air and/or induced draught fans, stokers, mills, coal distributers &c. at least one fan and some of the boiler auxiliaries being driven by a series turbine in the main steam stream from the boiler between two stages of the superheater so that the ratio of boiler steam to furnace air will remain substantially constant. A series turbine 6 is located in series with and at an intermediate point of a superheater 2-3 of a boiler 1 and drives an A.C. generator 8 whose output is fed to A.C. motors 9-12 which drive various boiler auxiliaries. A byepass control valve 16 is provided for the series turbine and for starting purposes the motors 9-12 may be connected through a switch 13 to an external current supply line 14. In a modification the A.C. generator 8 is driven through gearing by the series turbine 6 and an auxiliary turbine which latter is fed by leakage steam from the high-pressure gland of the series turbine and provides power to compensate for differences in power output of the series turbine and power requirements of the auxiliaries under varying boiler operating conditions. The series and auxiliary turbines also drive a D.C. generator which supplies current to motors for driving auxiliaries whose speed it is desired to regulate independently of the speed of the series turbine.
