Such an assembly may be incorporated in a heavy circuit breaker or switch 10 to assist installation and removal thereof relative to the live terminals 12a-12c of a switchboard. Pin terminals 26 on the breaker are drawn into sockets 30 on the switchboard by means of bolt and nut terminals 46, 52, the bolt 46 being rotated by means of the torque transmitting assembly 36. The similar, load, terminals 14, 24 at the base of the breaker and switchboard may be drawn together in a similar manner by a bolt (60, Fig. 2, not shown) and nut 52 connection but an isolating torque transmitting assembly is not required since the terminals can be disconnected from the supply by the breaker.

Title: Winding machines with means for forming waste and reserve windings
IPC: B65H54/34
Filed: 1975-03-26
Abstract: 1501428 Forming waste and reserve windings FMN SCHUSTER & CO 26 March 1975 [27 April 1974] 12584]75 Addition to 1456043 Heading D1J An apparatus for forming a waste and reserve winding on a spool and as claimed in claim 3 of the Patent Specification No. 1456043 is characterised in that the worm 30, Fig. 3, has at its inlet end 31 a predetermined number of thread guide grooves 30a of narrow pitch, for a waste winding, and immediately thereafter, at least one further thread guide groove 30b of larger pitch, for the reserve winding, extending to a run off at the outlet end of the worm.  The ratio of the larger pitch to the narrow pitch may be in the range 1:3 to 1:5. The worm 30 is driven by a constant - r.p.m. electric motor 32. In Fig. 4 the apparatus includes a slot 39 across which the thread I initially passes as it is first wound onto the spool 5. As the thread 1 becomes tensioned it presses against a feeler 33 that operates a switch to set the motor 32 in operation. As the thread 1 slips off the feeler 33 it passes in front of a blower 43 that blows the thread into a duct and thus tensions it until any slack has been taken up.

Title: Apparatus for controlling die casting machines
IPC: B22D17/10
Filed: 1968-03-15
Abstract: 1,213,065. Hydraulic apparatus. IDRAPRESSEN G. m.b. H. March 15, 1968 [March 15, 1967], No.2641/68. Heading F1P. [Also in Division B3] In a horizontal cold-chamber die-casting machine the molten metal plunger (not shown, but attached to the left of a plunger piston 4) is provided with a pressure intensifier comprising a cylinder 1 with a piston 2. At the beginning of casting pressure fluid is supplied at 27 and passes through the centre void of the piston 2 to force the plunger piston 4 leftwards thus injecting metal into the die, the centre valve of piston 2 being open. The piston 2 is held stationary by pressure fluid fed from a main 12 through an adjustable valve 13. As the plunger reaches the end of its injection stroke, a back pressure wave is produced which closes the centre valve of piston 2 which piston then begins to move leftward to meet the plunger piston 4 to apply the intensified pressure to the casting. The build-up of pressure in a chamber 7 in front of piston 2 opens a control valve 9 to force fluid into a pressure reservoir 8. The valve is spring biased and adjustable by a spindle 10. During most of the metal injection cycle the pipe 6 and pipe 14 on opposite sides of the spring biased valve seat 11 are connected through a four-way valve 15. Alternatively the pressure main 25 can be connected to the valve 9 via the valve 15. The spring biasing in valve 9 can be over-ridden by connecting the pipe 14 to an oil reservoir by operating the valve 15. The valve 15 is solenoid 19 operated through a timedelay 22. The signals for actuating the solenoid are derived from the fluid pressure in a cavity 20 in front of the intensifier piston 2. By adjusting the time delay 22 the instant during the metal injection at which the valve 11 opens to allow pressure fluid into the reservoir 8 can be varied to suit the type of casting.

Title: Improvements in or relating to the manufacture of moulded materials
IPC: B28B21/72
Filed: 1931-04-29
Abstract: In the method of making pipes and other hollow bodies of concrete by centrifugal moulding wherein the bodies immediately after moulding consist of superposed layers, one layer or set of layers containing the largest particles being hard and rigid but fragile, and the alternate layer or layers being coherent but deformable and composed of very fine concrete rich in cement, or of asphalt, the operation is carried out so that the one layer or set of layers has sufficient rigidity to compensate for the deformability of the other layer or set of layers, and the latter have sufficient coherence to compensate for the fragility of the former layer or set of layers so as to produce a stable body which is removed from the mould immediately upon cessation of the rotation of the mould.  The largest particles of aggregate should have linear dimensions lying between 1/4 and 1/7 of the thickness of the wall of the article and the inner coherent layer should have a thickness of 1/10 , or a little more, of the thickness of the wall and contain an amount of cement of the order of 70 per cent.  The article, particularly if of large diameter, is advantageously removed from the mould in an upright position.

Filed: 1953-05-07
Abstract: 733,321. Jet propulsion plant. NORTH AMERICAN AVIATION, Inc. May 7, 1953, No. 12744/53. Class 110 (3). [Also in Groups XXI and XXXIII] Guiding vanes for a rocket motor are constructed in laminar form, the inner layer 5 being of higher tensile strength than the outer layers 6. Preferably the layer 5, Fig. 4, is molybdenum and the outer layers copper, so that the vane is eroded by the hot gases from the propellant, the copper being eroded more rapidly than the molybdenum leaves a sharp leading edge 7 and streamline surfaces 8. Fig. 5 shows a vane constructed of several layers, the innermost layer 10 being molyb. denum or steel and the succeeding layers 11, 12, 13, 14 being copper, chromium, molybdenum and copper. In a modification of the arrangement shown in Fig. 4 the inner layer has a nose portion of increased sectional thickness which forms the leading edge of the vane. A layer of chromium may cover this vane, which may also be given a coating of ceramic material. Fig. 7 shows a modified vane 19 having an insert 20 of molybdenum fastened to the copper portion 21 by copper rivets 22. The insert 20 extends only partway along the vane. The leading edge of this insert may be cut away. On firing a rocket fitted with these vanes, the molybdenum and copper are consumed until the rivets 22 collapse, when the remainder of the insert falls away. The vanes may have a tongue portion 25, Fig. 11, which fits in a groove 29 in holders 26 on the motor casing 30 of rocket 31, Fig. 12. The rocket has fixed control surfaces 32, 33 and movable control surfaces 34, 35 which are interconnected with guide mechanisms. The vanes 19 are interconnected through holders 26 with shafts 36 attached to the movable control surfaces. Instead of molybdenum, the core of the vane may be made of tungsten, chromium, alloys or metallic carbides or oxides thereof, the outer layers being of copper, aluminium, silver, or alloys thereof, or wood, laminated phenolic resin - impregnated glass, graphite, or metallic carbides or oxides. These materials may be coated with other substances such as chromium to control the rate of burning.

Class 39(iv) U<SP>235</SP> is concentrated by bombarding uranium or uranium compounds with neutrons in the presence of a moderating element (e.g. H<SP>1</SP>, H<SP>2</SP>, He or C) and of an element (e.g. Cd or Dy) strongly absorbent of thermal neutrons, but non-absorbent of resonant neutrons, thereby promoting the reaction U<SP>238</SP>+n# 94 X<SP>239</SP>. Then uranium (enriched in isotope 235) is separated chemically. Preferably a mixture of uranium, water (or other hydrogen compound) and cadmium surrounds a neutron source comprising U<SP>233</SP>, U<SP>235</SP> and/or  94 X<SP>239</SP>. Compounds of uranium and cadmium may be used in lieu of the metals themselves. The number of  91 X<SP>239</SP> atoms produced in the outer system must at least equal the number of  94 X<SP>239</SP> or U<SP>233</SP> or U<SP>235</SP> atoms consumed in the inner system. When the mixture contains equal numbers of uranium, hydrogen and cadmium atoms, destruction of U<SP>238</SP> to produce  91 X<SP>239</SP> is stated to be about 1500 times faster than destruction of U<SP>235</SP>. When the neutron source supplies 1.5 neutrons per fission to the outside system, the hydrogen/uranium ratio should not exceed 1; and when 2 neutrons per fission are supplied this ratio rises to 2.
