Title: Improvements in and relating to the control of electric generators and interconnected motors
IPC: H02P7/34
Filed: 1926-06-03
Abstract: 253,127. British Thomson-Houston Co., Ltd., (Assignees of Macmillan, C.). June 3, 1925, [Convention date]. Dynamos and motors combined for transmitting power.-In a system comprising an induction motor supplied from an alternating current generator the variations of secondary circuit resistance to obtain variations of motor speed are associated with abrupt changes of excitation of the generator so that either (a) a series of definite speeds without great variation of primary circuit voltage or (b) a steady variation of motor speed may be attained. The means for varying the secondary circuit resistance are correlated with means for suddenly increasing or decreasing the excitation of the primary circuit so that, allowing for the true constants of the circuits, each alteration of secondary circuit resistance may be accompanied by a sudden variation of field excitation in the appropriate sense, followed by a gradual variation of excitation as the motor accelerates. An arm 32 controlling the field circuit resistance is geared to a sector 23 controlling current supplied to contactors 16 - - 19 controlling the rotor resistance 2 so that one turn of the arm moves the sector over the space between two adjacent brushes 25 - - 28. Movement of the arm 32 counterclockwise from the position shown suddenly reduces the field excitation and causes the sector 23 to energize contactor 17 to reduce the rotor resistance, thus producing a gradual acceleration of the motor at each variation of rotor circuit resistance. By reversing the switch 31 a reduction of rotor resistance is accompanied by a sudden increase of generator excitation followed by its slow decrease as the motor accelerates, this arrangement providing a series of definite motor speeds without great variation of voltage.

Patent GB-858061-A (GB)
Title: Composite nuclear fuel element and method of manufacture
IPC: B22F3/02
Filed: 1957-05-06
Abstract: Compacts of oxides of fissionable material, particularly uranium and thorium, are formed by agglomerating the oxides with a heat decomposable resinous binder to form freeflowing granules which are cold pressed in a die and sintered in a dry non-oxidising gas to decompose and remove the binder.  The compacts so formed are placed in a corrosionresistant metal tube of low neutron absorbing cross-section and employed as a fuel element in nuclear reactor.  A binder specified is polyvinyl alcohol which may be employed in admixture with a die lubricant such as a hydrogenated vegetable oil or aluminium stearate.  The treated oxide may be subjected to a die pressure of 125 tons per square inch whereby the compact of uranium dioxide for example has a density which is 70% of the theoretical. In a modification, the resinous binder may be removed prior to sintering in a continuously flowing stream of carbon dioxide at 500 to 900 DEG C. after which the compacts may be sintered in an inert gas such as argon.  The combined sintering and resin removal may be effected by heating in a hydrogen at above 1500 DEG C.  The density of the final compact is about 98% of the theoretical.  For employment as a nuclear reactor fuel, the compacts preferably have a length diameter ratio of 1 and are ground down accurately in respect of thickness and diameter so as to fit closely against each other and to the tubular metallic container in which they are placed. Specification 767,892 is referred to. p

Abstract: 824,855. Control of D.C. motors. IGRANIC ELECTRIC CO. Ltd. May 9, 1956 [June 16, 1955], No. 14399/56. Class 38 (3). A braking system for a shunt-wound motor 10, having a field winding 12 and control rheostat 16, comprises a relay 18 which is actuated in an emergency to close contacts 18b, 18c. This causes the rheostat 16 to be shunted so that the full voltage of source L1, L2, is applied to the winding 12. At the same time, the field winding 26 of a generator 24 is energized, and the generator voltage is added to that of the source L1, L2. Thus, the field current is increased rapidly to a value above normal and the motor 10 is braked. In a modification, the generator 24 is replaced by a bridge rectifier supplied from a transformer, the rectifier being polarized to permit current-flow from the source L1, L2, through the field winding, Fig. 2 (not shown). Upon closure of contacts 18c, the rectified current is added to that derived from the source L1, L2, and passing through the field winding. Normally-closed contacts may be substituted for the contacts 18b, 18c, in which case the relay 18 is de-energized when an emergency stop is required.

Abstract: 1,108,306. Audible signalling. AGA AKTIEBOLAG. 6 April, 1965 [4 May, 1964], No. 14526/65. Heading G4F. [Also in Division H3] An amplifier for intermittently amplifying an applied alternating current signal comprises at least one transistorized amplifying stage, means operable in the absence of a control signal to block the alternating current signal and responsive to an applied control signal to allow the transistorized stage to amplify the alternating current signal for the duration of the control signal and rectifier means 15, 16 responsive to the alternating current signal to apply a D.C. blocking voltage to the transistors of the stage during the time the alternating current input signal is blocked so as to reduce the current consumption of the amplifier. When a negative voltage is applied at 14 to the base of transistor 13 this transistor conducts to connect the oscillator output from transistors 5 and 6 to the amplifier stages 8-11 which supply a load 12. The circuit may be used to drive a sound transmitter of a sonic buoy. The control voltage at 14 is sufficient to overcome the effect of the voltage output from the rectifiers 15, 16 which turns transistor 13 off when no control voltage is applied. Also the bias applied to the output transistors 10 and 11 by diode 21 increases when the amplified oscillations from the transformer 20 occur so as to enable further amplification to be attained.
