Title: Improvements relating to fuelling machines for nuclear reactors
Inventor: COLLIER DEREK
IPC: G21C7/12
Filed: 1963-02-04
Abstract: 1,083,460. Winches. FAIREY ENGINEERING Ltd. May 4, 1964 [Feb. 4, 1963], No. 4533/63. Heading B8B. [Also in Division G6] A machine 10 for transferring nuclear reactor fuel elements or control rods by means of winches and movable over the reactor charge floor on a chassis as disclosed in Specification 9794/63 for alignment with a selected standpipe comprises a mushroom-shaped pressure shell 10A having a head 13. A platform 17 carries three similar winches 18 any one of which may be selected and brought to a common operating station by rotating the platform through its toothed periphery 16. An electric motor 15 for alternatively driving the platform 17 or the selected winch 18 transmits its drive through a gear-box 39 to a vertical shaft 12 axially movable and rotatable in a housing 20. Axial movement of the shaft 12 is obtained through an hydraulic jack 33 operating a rod 40 through a lever 35, the rod abutting the lower end of the shaft. The upper end of the shaft carries two ring members 45, 46 having internal teeth 47, Fig. 4, such that when the shaft is in its lower position the gear ring 46 engages teeth 48 on a rotating collar 50, further teeth 54 on the collar driving the platform teeth 16 through gearing 55, 56. When the shaft 12 is raised as shown in Figs. 1, 4 the gears 46, 48 disengage and the gear ring 45 engages a pinion secured to thelower end of a vertical drive shaft (Fig. 6, not shown) of the selected winch 18. The winches are constructed as disclosed in Specification 4534/63 and automatic alignment between the gear teeth on the shaft 12 and the co-operating gear teeth is assured by the arrangement disclosed in Specification 4532/63.

Abstract: 840,041. Moulding cartridge cases. LEFEBVRE, J. M. Feb. 11, 1957 [Feb. 13, 1956] No. 4556/57. Addition to 765,502. Class 87(2). [Also in Group XXI] The invention of the parent Specification is modified by pre-moulding by injection a ring 10 round the primer 3, preferably of cheaper plastic material than that of the casing 13 and same order of injection temperature, and injection-moulding the casing around the cap and ring. The mass of plastic material which requires time for cooling in one operation is thus reduced. To enhance adhesion the ring 10 may be formed with through-holes and grooves which become filled, in the main moulding operation, with plastic material 13c, 14, 15. Adhesive may also be used.

Title: Apparatus and method for producing elongate metallic bodies
IPC: B22F3/00
Filed: 1955-02-16
Abstract: 774,937. Powder metallurgy; continuouscasting. BRENNAN, J. B. Feb. 16, 1955 No. 4636/55. Classes 83 (1) and 83 (4). Elongated metal - articles, e.g. strips or rods, are manufactured by compacting metal particles into a tube, moving them along the tube whilst sintering them, and expelling the sintered product at the other end of the tube. After sintering, the metal may be rendered molten, and frozen whilst still in the tube, thus giving a solid cast body. The powder from a hopper 1 is pushed by a reciprocating piston 5 along the tube 6, sintered by induction-heaters 9, 15, and cooled by a cooling-chamber 11. The zone 12 may consist of molten metal. Inert-gas may be supplied at 14, 14a, and if the process is to be carried out under a vacuum, the air may be evacuated at 20, through a filter 16. A feedscrew may be substituted for the piston 5. Sealing-means 17 may be provided at the outlet.

Abstract: 564,324. Cooling extrusion-coated wires. BRITISH INSULATED CABLES, Ltd., STEWARD, H. M., BLACKBURN, R., CARSTEN, H. R. F., and PACKER, J. L. March 22, 1943, No. 4637. [Class 87 (ii)] The coated wire is cooled gradually by passing it through a bath or baths of fluid which decrease in temperature in the direction of travel of the wire. Thus, the wire may pass through three water baths in succession, the first being steamheated and only a little cooler than the wire, the second also being steam-heated but much cooler and the third being at room temperature. Alternatively, only one bath 31 may be used, the drop in temperature from left to right being attained by introducing cold water at 14; steam passes from left to right through pipe 33, hot water falls over a lip into a waste pipe 35 and the coated wire 3 leaves the bath through a rubber packing at 36. The trough 31 may slope towards the left.

Title: Improvements in or relating to medical respirators
Inventor: KIPLING BARRY JOHN
IPC: A61M16/00
Filed: 1969-01-30
Abstract: 1,248,301. Respiratory appliances. PYE Ltd. 26 Nov., 1969 [30 Jan., 1969], No. 5107/69. Heading A5T. A time cycled medical respirator comprises a face mask, supplied with anaesthetic gas by a fluidistic multivibrator, having two alternate periods, each determined by a variable volume capacitor VV1, VV2 which causes a bellows P to expand during one period drawing respiratory gas from supply N through a non-return valve NR1 and allowing exhaled gas to be vented at the mask, via valve R, and to contract during the other period forcing gas from the bellows via a non-return valve NR2 in line 3 to the mask. The bellows P has an adjustable maximum volume determined by the position of a member X as controlled by a knob Y, attached to the member X and the movement of the bellows controlled by the fluid flow into the piston-cylinder arrangement U,V. The fluid used in operating the multivibrator, is air under pressure. With the switch MS open, driving air from source H1 is supplied to the port A in valve CO1 so that the air passes from port C to port E and an adjustable time delay valve VR2, TD2 into a variable volume fluid container VV2. When the container VV2 is full, the valve VR2, TD2 closes and the container VV2 is vented to the atmosphere and a second time delay valve VR1, TD1 connects an air supply H2 to the port B to changeover the valve CO1, so that port D connects to port C. A similar cycle occurs in the circuit comprising time delay valve VR1, TD1 and variable volume container VV1, after which valve CO1 changes over to connect port C to port E, the time spent in each position being dependent on the variable volumes VV1, VV2 and the settings on the variable restrictions VR1, VR2 in the time delay valves TD1, TD2. When ports C E are connected together, driving air passes through the load line 2 to the port B3 of changeover valve C03 to open valve R for passage of respiratory gas to the mask, and to port B2 of the changeover valve CO2 which moves to allow air from source L2 through a pressure regulator PR2 and ports C2 and D2 to piston cylinder V to move piston U to contract the bellows forcing gas to the face mask. With ports C and D connected together, the load line 1 to port A3 of changeover valve CO2 is connected to the other end of the piston cylinder allows air from source L3 through a pressure regulator PR3 and ports C3, and E3 to move the piston so to expand the bellows drawing fluid from the supply N through a non-return valve NR1, to complete the respiratory cycle. The valve R, Z may be incorporated either in the face mask or the respirator. A valve R2, Z2 (Figure 2 not shown) similar to that R, Z employed in the face mask may be controlled from port E2 of the changeover valve C02 to allow gas to pass through the non-return valve NR1 only when the bellows are expanding, and the exhaled gas is discharged from the face mask.
