Abstract: 1298887 Automatic speed control ERA ELEKTRONIK-REGULAUTOMATIK GmbH & Co K G 20 April 1970 [18 April 1969] 18820/70 Heading G3R [Also in Division H2] The stator windings of a squirrel cage motor are supplied through back-to-back thyristors or the equivalent in each supply-line of a three phase source. Triggering pulses for the thyristors are derived from generator stages 42 associated with synchornizing stages 31, 32, 33, which are coupled through transformers to the mains. A regulator 80 is connected to a tachometer generator 2 and to a speed-setter 17, the generator being of the polyphase synchronous type whose output is rectified by bridges 21, 22, to provide a D.C. signal having a ripple component. A transistor 810 is controlled in accordance with the difference between the signals from the components 2 and 17, and receives an additional control signal from storage capacitor 870 through resistor 851 and capacitor 850. The transistor 810 is cascaded through a transistor 820 to a transistor 830 which regulates the rate of charge of the capacitor 870, the switching- operation of the transistor 830 taking place at high frequency. The reference voltage derived from the potentiometer 17 is made to increase slowly by means of transistor 840 controlled by timing network 845, 842. The output from capacitor 870 is applied to stages 31, 32, 33 in which transistors 321, 322, 333 are switched on and off at mains frequency. A capacitor 425 is charged through the transistor 322 to boost the voltage from line 610 whereby a triggering pulse is transmitted to transformer 427, through field-effect transistor 421. This determines the basic torque, for constant speed control, further signals from the capacitor 870 are supplied to the capacitor 425 through the transistor 321. The triggering pulses are transmitted through the lines 720 to the main thyristors in the motor circuit.

Abstract: 741,774. Centre punches. EAST H. G., [trading as EAST & CO., H. G.]. June 30, 1954 [July 8, 1953], No. 18908/53. Class 61 A spring actuated instrument such as a centre punch or a needle gun, as shown, comprises a spring - controlled piston 12 fitted with a plurality of spring-pressed balls 13 or the like in radial bores therein which hold the piston against movement, with respect to the body 11 of the instrument, upon initial manual pressure on an operating member 17. By this means energy is stored in the piston control spring 20 and is subsequently released, upon further movement of the member 17, to enable the piston to impart a blow on the punch or needles 25. In the construction shown the release of the piston is effected by the action of a cam surface 21 on the member 17, which surface moves the balls inwards from locking engagement with recesses in the body 11. The piston, on release, strikes a spring-controlled rod 27 carrying a block 26 fitted with the needles 25. When manual pressure is released from the member 17 the rod 27 returns to its initial position shown by a spring 31. An apertured needle guard 24 is carried by a cap 23 screwed to the body 11. In a modification the piston slides in a sleeve fitted to the body 11.

Title: Improvements in or relating to the manufacture of nuclear fuel elements
Inventor: PRICE MICHAEL STUART THOMAS
IPC: G21C3/62
Filed: 1968-04-22
Abstract: 1,249,156. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 2 April, 1969 [22 April, 1968], No. 18985/68. Heading G6C. A fuel element is formed from fuel particles having a fission product retaining coating by the application of a further coating comprising 20 to 70% by weight of powdered graphite, the remainder being synthetic resin, and heating a mass of the particles in contact with one another to form an agglomeration of fuel particles. The particles are tumbled in a rotating drum with the resin-graphite powder mixture, e.g. a mixture, in equal proportions by weight, of powdered graphite and phenolformaldehyde resin powder, dusted on to the particles from a vibrating sieve. Every few seconds the vibration is halted so that the feed of powder is stopped and a short burst of a solvent for the resin, e.g. methylated spirit, is sprayed into the drum. After a layer of the desired thickness has been deposited, the alternate supply of powder and solvent is stopped and the tumbling continued until the particles are hard and dry. The particles are now ready for forming into an agglomerate either by a simple moulding process or by being poured with or without vibration into a cavity in a graphite body and cured in situ. In the case of an annular cavity, a thin polythene film is wrapped around the inner face of the cavity. The body is then heated to 200‹ C. in air to cure the resin and then placed in a furnace purged by a stream of inert gas and heated to 800‹ C. to carbonize the resin. A final heat treatment is carried out at 1800‹ C. in vacuum to degas the agglomerate. The polythene film decomposes during the heat treatment so leaving an annular clearance which allows the agglomerate to contract towards the axis of the body without cracking longitudinally.
