Title: Improvements relating to resilient devices
Inventor: BINNEY ERIC ALTON
IPC: F16D3/50
Filed: 1949-11-30
Abstract: 682,598. Universal joints. ENGLISH ELECTRIC CO., Ltd. Nov. 24, 1950 [Nov. 30, 1949], No. 30726/49. Classes 80 (ii) and 80 (iv). [Also in Group XXX.II] A resilient coupling device, shown as a universal joint, comprises driving and driven members 10, 11 having cylindrical portions 10a, 11a, interrupted so as to form axially extending fingers carrying arcuate plates 13, to which are bonded rubber masses 12. The rubber masses 12 are also bonded to arcuate plates 14 clamped in rings 15, 16 having internally coned faces, so that tightening of bolts 17 compresses the rubber radially. Rotational movement between the driving and driven members is limited by the overhang 12a of the rubber on the arcuate plates 13. As applied to a drive for a track wheel of an electrically propelled vehicle, one part of the coupling is connected to a toothed wheel rotatable on a rigidly mounted quill while the other is connected to the track wheel. A unitary clamping ring may be drawn by bolts onto coned surfaces on the outer arcuate plates to compress the rubber radially, or alternatively a clamping ring in four segments may be used for this purpose, each segment being bolted to its two neighbours. The device also has applications to the resilient suspension systems of motors, engines and the like.

A. ; 1012, West Wayne Street, Fort Wayne, Indiana, U.S.A.) Nov. 3, 1932, No. 31046. Convention date, Nov. 3, 1931. [Class 38 (iv).] Boosting by transformers.-In illumination supply circuits where a series saturable reactor 5 controls the voltage across the load 2, the residual drop in the reactor when it is saturated is compensated by introducing a voltage at 8 which varies inversely as the impedance of the reactor 5. The voltage is injected by the series winding 8 of a transformer the primary 9 of which is in shunt with the mains in series with a variable impedance 10 which varies with and in the same sense as the impedance of the reactor 5 so as to increase or reduce the boost provided by the winding 8. The impedance in series with the winding 9 may be a saturable reactor 10 supplied in parallel with reactor 5, or it may be a self-saturating reactor or an impedance having a negative volt-ampere characteristic, or the winding 9 may be connected in series with the reactor 5 itself across the mains. The supply for the saturating windings of the reactors 5, 10 may be from D.C. mains or may be taken from a gas discharge rectifier arrangement 11, 12, 13 the output of which is controlled at 16 by a phase shiftable voltage on the grids of the rectifier tubes. The saturable reactors are of the split winding type and prevent resonance and harmonic effects due to saturation and also prevent coupling of A.C. with the D.C. winding. Specification 377,318 is referred to.

In a PABX having access to a STD network wherein the frequency of the metering impulses depends on the distance of the connection, calls emanating from certain extensions are interrupted when a predetermined number of metering impulses have been recorded. As shown, when an extension ET is connected over an exchange line EL metering impulses are supplied from apparatus MP to a detecting circuit MDC. A storage circuit SC counts the impulses, and after a certain number operates a circuit WC to give a warning tone and subsequently a circuit RC to release the connection. Privileged extensions, however, make connection to a wire DL which inhibits the circuit SC. Where the apparatus is located at a telephone instrument it may be disabled by the use of a special key by an authorized party.
