Filed: 1958-10-15
Abstract: 899,360. Wrenches. WACKETT, L. Oct. 15, 1958, No. 32946/58. Class 61. An adjustable wrench comprises a jaw 4 fixed to a sidewardly projecting portion at the head of the stock or handle 3 and a movable jaw 12 pivoted to the handle 3 by a pivot pin 11 which is adjustable, the jaw 12 being actuated by a compound lever device including a hand lever 5 pivoted at 6 to the handle 3 and a second lever 10 adapted to turn in the same sense as the lever 5, the pivot point 8 between the first and second levers is adjustable in conjunction with that of the movable jaw to enable the mechanical advantage of the compound lever device to be increased as the movable jaw is adjusted to accommodate larger nuts.

Title: Improvements relating to regulating arrangements for electrical circuits
IPC: G05F3/06
Filed: 1938-11-15
Abstract: 521,314. Automatic regulation. HARMER, H. M., and CANUT, A. F. Nov. 15, 1938, No. 33229. [Class 38 (iv)] Constant current through a load of varying resistance is obtained by equal inductive and capacitative devices in series with a source of A.C. and means including one or more transformers or auto-transformers by which the voltages across these devices are opposed to one another in series across the load. Two transformers T1 T2 associated respectively with a condenser C<SP>1</SP> and an inductance L may be connected in series across the supply VS and in series opposition across the load R. The inductance may itself serve as transformer or auto-transformer and in certain circumstances the transformer T1 may be dispensed with. In order to limit the voltage occurring across a high resistance load and across the reactances the transformer T1, or a substituted choke or auto-transformer may be arranged to saturate at a given load resistance or reactance voltage since the current through the reactances varies with the load resistance. In the case of load resistances above their critical value a load circuit voltage which is constant and independent of load resistance and of supply voltage variations may be obtained by introducing by a transformer or auto-transformer supplied from VS an additional voltage into the load circuit. The load may be supplied through any kind of rectifier and two or three supply phases may by this means be paralleled on a load to provide a low ripple D.C. A two phase supply to a load may be obtained from a single source by taking a second circuit to the load through a barretter. The third harmoni in the circuit T1, C' may be reduced by a series circuit resonant thereto, e.g., by an inductance in series with the condenser C<SP>1</SP> across T1. The value of the constant current may be determined by the relative transformation ratio of the two transformers or by'a switch S, Fig. 2, whereby condensers may be transferred from one transformer circuit to the other, changing the effective value of the reactances while maintaining them equal.

Title: Pencil type nuclear fuel assembly

Abstract: 1343877 Fuel elements COMMISSARIAT A L'ENERGIE ATOMIQUE 17 July 1972 [29 July 1971] 33279/72 Heading G6C A nuclear fuel assembly of the type comprising a bundle of canned fuel pencils 10 arranged parallel to each other in an envelope 12 bounding a coolant duct has a sheet metal member 16 bearing on the envelope 12, the member 16 taking the form of a number of thin panels each placed up against an inside surface of the envelope 12 and having corrugations 18 not parallel to the fuel pencils 10, and determining the minimum spacing between the peripheral pencils 10 of the bundle and the envelope 12. The minimum spacing between each fuel pencil 10 and the adjacent pencils is determined by helical bracing members 14 borne by the pencils over at least most of their length. The corrugations 18 may in cross-section be semi-circular (or semi-elliptical) or be sharp-cornered bends, and they may extend transversely of the fuel pencils 10 or be inclined thereto. The sheet metal member 16 is formed with perforations so that the coolant can flow freely through the corrugations and reduce pressures tending to deform the sheet metal member. The perforations are formed in the corrugations 18 as evenly spaced holes (20, 20a) (Figs. 2 and 3, not shown) or as occasional discontinuities or saw cuts. The sheet metal member 16 may be corrugated only over that part opposite the fissile material-containing regions of the fuel pencils 10, in which case those parts of the member 16 upstream and downstream of the corrugated part are thicker than the latter and bear on the bracing members 14 of the adjacent fuel pencils. The fuel assembly described is for use in a liquid sodium cooled fast reactor.

The pulverized material is delivered through a spout R, and air from a fan may be admitted to the chamber J by apertures S, S<1> fitted with valves. The air draught may be used to cool the plate H. Suitable spouts from the discharge spout R return insufficiently-pulverized material to the chamber J. The machine may be arranged either vertically or horizontally, and any convenient number of beaters A and plates H may be used.

Abstract: 1,112,098. Telegraphy. SIEMENS A.G. 27 July, 1966 [28 July, 1965], No. 33765/66. Heading H4P. In a teleprinter exchange of the type in which each bit marks a combination of channels in a multichannel line SV to which all subscribers are connected, the combination being unique to the called subscriber, the subscriber transmitters are in groups and are multiplexed on to the line. As shown there are two groups comprising units KS1-KS62 and KS63-KS125. When a call-up pulse on line AL reaches the last stage of either group it sends a pulse on line FL1 or FL2 to all stages in the other group so that a bit from any subscriber in that group is stored on the corresponding store NAS. If, for example, KS1 receives a bit gate a is enabled and the next call-up pulse passes through gate a to read out the bit stored in NAS and to transmit the bit on a combination of channels SV. This transmission causes AI to generate a call-up pulse which passes to the next stage. If KS2 has no bit in NAS gate u is enabled and the call-up pulse passes to the next stage KS3, and so on. The data from the subscribers are thus multiplexed on the line, the cycle time depending upon the number of subscribers who are transmitting. When the call-up pulse leaves KS62 data is read in to the stores of the other group and transmission proceeds as before.
