IPC: H02P9/10
Filed: 1928-05-14
Abstract: 290,576. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). May 13, 1927, [Convention date]. Exciting; protective or safety devices, auxiliary.- A continuous - current dynamo-electric machine 10 is protected against overload by causing a surge of armature current to oppose the normal current flow in the field winding 15, and for this purpose separate exciting means, such as an exciter 17, are connected in a closed circuit with the field winding and a choke 18 having higher impedance than the field winding and through which current is conducted from the armature to the distributive system 13, 14 in the same direction as the exciting current. The machine 10 has a commutating field 16 and if desired a compensating winding connected in series therewith. Normally, the whole of the armature current of the machine 10 passes through the exciter 17 and choke 18, but on the occurrence of surge, the major portion of this current is diverted through the field 15 and thus demagnetizes it. As the reduction of the field would cause excessive sparking at the brushes of the machine 10, a shunt circuit 19 is provided having such a resistance that normally a negligible current flows there through, but having a very low inductance so that upon the occurrence of a surge a large current flows therethrough. In a modification, the end of the commutating field 16 is connected to a point between the exciter and the choke, instead of between the. exciter and the field 15.

Title: Coupling device for relatively rotatable members
IPC: F16D41/07
Filed: 1973-03-23
Abstract: 1428476 Freewheel clutches; one-way brakes BORG-WARNER GmbH [trading as STIEBER DIVISION] 23 May 1973 [27 March 1972] 14183/73 Headings F2E and F2F In a one-way coupling, clutch or brake, sprags 5 are pivoted on pins 6 which extend between lateral cage discs 8, the sprags 5 have radial free play relative to the inner and outer races 2 and 4 on inner and outer members 1 and 3, the discs 8 being frictionally connected to the inner race 2, springs 12 biasing the sprags 5 in the coupling direction and centrifugal force acting against springs 12 to rotate and radially move sprags 5 clear of the races 2 and 4, the pivoting being limited by noses 17 engaging pins 16. The radial free-play a is shown in Fig. 2 between a sprag 5 and its pivot pin 6, but this may alternatively be between the pin and the bores in discs 8. In clutch operation, with the outer race 4 rotated clockwise as viewed in Fig. 1, to transmit torque from an outer part 3 to a shaft keyed to inner member 1, the clutch locks to transmit the torque and remains so until the driving torque is removed, at which time, if the speed of the inner member is high enough, the centrifugal force can disengage the clutch against springs 12, the torque holding the clutch engaged before it is removed. The clutch re-engages when the inner member 1 has slowed sufficiently to allow springs 12 to overcome centrifugal force. If the speed of outer part 3 is too great relative to inner member 1 on re-engagement the frictional coupling between discs 8 and member 1 slips. As a one-way brake, with outer member 3 stationary the inner member 1 can only rotate clockwise, the sprags 5 lifting off the races due to centrifugal force if the speed of the inner member 1 is sufficient.

Abstract: 913,512. Photo-electric flame detection. ETHER Ltd. June 19, 1961 [April 27, 1960], No. 14726/60. Drawings to Specification. Class 40 (3). Each flame of a multiple flame burner has an associated photo-electric device for monitoring it and each of these is connected to a respective one of a plurality of transistor circuits all connected to a single relay which is thereby caused to interrupt the burner fuel supply should at least one flame fail. Photoconductive cells are used for monitoring and each is connected to an associated transistor amplifier having a pass-band encompassing the range of frequencies comprised of short term periodic intensity fluctuations found in flames. The output resistance of each amplifier changes when the associated photo-cell is irradiated and the outputs are all connected either in series or in parallel with the fuel supply relay. This may be shunted by a capacitor to obviate release due merely to the short term flame intensity fluctuations and time delay means may be provided to inhibit release during burner starting. The photo-cells may be responsive to infra-red radiation.
