Abstract: 1,126,396. Fuel elements. ATOMIC ENERGY OF CANADA Ltd. 22 June, 1967 [18 July, 1966], No. 28965/67. Heading G6C. A fuel element comprises a core 10 of nuclear metal fuel with a void space 11 surrounded by a sheathing assembly consisting of inner and outer sheaths 12, 14 separated by and in contact with a continuous ductile interlayer 13. The core 10 is preferably formed from U metal having minor alloying additions to reduce swelling upon irradiation. The U may contain up to 1.5 wt. per cent of any of Fe, C, Cr or Si either individually or in combination and should be heat treated by being beta quenched from about 750‹ C. and annealed at about 550‹ C. for several hours to produce a fine grained randomly oriented structure containing a fine precipitate. Other U alloys which may be used contain up to 10 wt. per cent Zr or Al, or up to 1 wt. per cent Mo or Nb. The void volume is between 2 and 15%, preferably about 5% of the U volume. Natural or enriched U, or alternatively other fuel metals and their alloys such as Pu, Th, Pu-U, Th-U may be used. The inner and outer sheaths 12, 14 are formed from a corrosion-resistant Zr alloy, preferably Zircaloy-2, with Zircaloy-4 and Zr containing about 2À5 wt. per cent Nb also being suitable. Circumstances may occur in which stainless steel or a Ni-Cr alloy is suitable for the sheaths. The preferred material for the interlayer 13 is extremely ductile material formed by alloying A1 with from 0 to 25 wt. per cent U, preferably about 10 wt. per cent. The U alloy provides a monitoring signal on fracture of the outer sheath 14. A non-fissile material such as Pb or a ductile alloy may, however, also be used for the interlayer 13. The end cap assemblies each consist of two portions 15, 16, portion 16 being welded to the inner sheath 12 and portion 15 to the outer sheath 14. The fuel element is fabricated by: (a) co-extrusion of the core 10 and the inner sheath 12 followed by slip fit assembly inside the interlayer 13 and the outer sheath 14, the outer sheath then being reduced in diameter by swaging or drawing to provide intimate contact between the layers, (b) individual fabrication of the component parts and slip fit assembly followed by swaging or drawing, or (c) assembly of the core 10 and the inner sheath 12 by co-extrusion or slip fit assembly followed by extrusion cladding of the interlayer 13, the assembly so produced then being slip fitted into the outer sheath 14.

Title: An improved x-ray table
Inventor: WARDEN HANS ERIK
IPC: A61B6/04
Filed: 1967-06-26
Abstract: 1,120,939. X-ray table. JARNHS ELEKTRISKA A.B. 26 June, 1967 [29 June, 1966], No. 29279/67. Heading H5R. A table for supporting a patient during an X-ray examination comprises a base or stand having a table top slidably mounted thereon, said top being provided with two channel section guide tracks in which rollers mounted in pairs are adapted to engage, said rollers being attached to a member which is pivotally mounted on the base or on a carriage slidably attached to the base, such that the pairs of rollers automatically engage with or disengage from the channel guides as the top is placed on or lifted off the supporting structure. As shown in Figs. 1 and 2, a carriage 4 slidably mounted on base 5 by means of roller 6 and channel members 7 comprises pivotally mounted members 8 running longitudinally of the table top 1. To 8 there are attached pairs of rollers 9 and 10, wherein 9 is preferably smaller than 10, and wherein as most clearly shown in Fig. 2, the rotation axes of the two rollers are inclined at an angle to each other. Preferably, as shown, the pivot axis of member 8 lies along the lower edge thereof and the rollers 9 and 10 are attached adjacent the upper edge thereof, the member 8 being so balanced that when top 1 is not in position it exhibits only sufficient an inclination to the vertical so that on placing the top 1 in position member 8 will pivot outwards due to the pressure on rollers 10, and the rollers will thus automatically position themselves on appropriately angled bearing surfaces in channel member 3 (Fig. 4, not shown). In removing the top the lower edge of channel member 3 cooperates with roller 9 to pivot member 8 so that the rollers disengage from the bearing surfaces. Locking means, for example an electromagnet (Fig. 3, not shown), may be provided to fasten the top 1 in any position.

Title: Improvements in or relating to servo-operated hydraulic braking systems
IPC: B60T11/18
Filed: 1954-10-13
Abstract: 752,747. Fluid-pressure servo-brakes. BENDIX AVIATION CORPORATION. Oct. 13, 1954 [Nov. 12, 1953], No. 29530/54. Class 103 (1). A spring-loaded valve member 92 is fitted at the outlet from the slave cylinder of a vacuum servo booster unit for hydraulic brakes which is such that in combination with the pressure needed to expand the brake shoes 28 against spring 29, it requires, to open it, a pressure in the slave cylinder 22, which will be in excess of that necessary to cause operation of the relay valve 65 controlling movement of the servopiston 18. This ensures that a substantial volume of liquid is not displaced from the master cylinder 57 past the slave piston 34 direct to the brakes before the servo-piston comes into effect, under which circumstances the master cylinder piston 55 might bottom and become ineffective for emergency direct operation. As shown in Fig. 2, the passage of fluid through the slave piston 34 is controlled by a ball valve 48 and seat 51, the substantial equalization of pressure on each side of the piston caused by the valve member 92 resulting in the ball 48 being urged away from its seat by the spring 49. A lightly loaded valve member 96 beyond the valve 92 provides for compensating fluid to the brake motor cylinders direct from the master cylinder reservoir. A modified form of slave piston having only a single passage therethrough is also described. Specification 620,593 is referred to.

Abstract: 464,799. Automatic control systems. STANDARD TELEPHONES & CABLES, Ltd., and ARMSTRONG, L. J. HEATON-. Oct. 25, 1935, No. 29532. [Class 38 (iv)] Temperature.-When a body to be maintained at constant temperature is placed within a thermostatically controlled chamber of good heat conductivity, the thermometric time lag and the effect of temperature gradient in the space surrounding the body are minimized by placing adjacent to the body heated an auxiliary heat source, small with respect to the main source of heat, and controlled by the thermostatic device. As shown in the Figure the main heat source comprises electric resistances 3. A small portion thereof is placed at 6 under the body 1 which is to have its temperature maintained constant and the thermostatic means 2 controls the supply of current to both. The resistance 6 may be adjusted to give any desired correction for variations in ambient temperature.

Abstract: 966,089. Copying. A. MOOSMANN. Aug. 26, 1960 [Sept. 11, 1959], No. 29600/60. Heading B3T. [Also in Division G3] A pneumatic control mechanism such as for a tool slide in a machine tool, comprises a member 20 whose position is to be varied by subjecting it to pressures, in opposite directions, by two channels 3, 4 and 11, 12 connected to a common source 1, each channel including supply and receiving nozzles 7, 9 and 8, 10 respectively and a movable control member 15 displaceable transversely to the nozzles whereby the pressures in the two channels are simultaneously varied in opposite directions. As applied to a machine tool, a template 25, Fig. 1, acts on a pin 26 fixed to a pivoted member 28 which, through a pivoted lever 31 and pin 35, moves a spring-loaded pivoted lever 16. The control member 15, in the form of a vane, is attached to the end of the lever 16 and positioned between two supply nozzles 7, 8 and two receiving nozzles 9, 10; the vane is provided with control edges 18, 19 as shown in Fig. 3, so that, upon movement of the vane, the output from the other pair is increased a corresponding amount. The pressure differential produced by the nozzles is applied to the ends of a relay valve 20, Fig. 5, which controls the supply of oil to a power piston connected to the tool slide. Alternatively, the differential pressure may be applied to opposed pistons adapted to move a nozzle supplying pressurized oil to a pair of turbine wheels actuating the tool slide. In a modification, the lever 16 can be moved by a piston through a pin 38 in response to pressure applied to a piston 37.

Title: An improved method of and apparatus for filleting fish
IPC: A22C25/16
Filed: 1927-11-07
Abstract: 289,720. Baader, R. Nov. 7, 1927. Fish, dressing.- Previously decapitated and split fishes are cut into fillets by resting each fish with its belly cavity on a block which moves it towards four rotary cutter discs, two of which revolve in fixed planes and are laterally separated to cut, on the upper side of the fish, on each side of the backbone, and the other two revolve on axes which are angularly displaceable, and cut on the other side of the fish in such manner that the prismatic portion of the backbone and the rib bones are cut away. The action of the cutters which are toothed, is shown in Figs. 5, 6. The fish is supported on the block 6, the cutters 10, 11 cut away the back fin, whilst the cutters 12, 13 are angularly disposed to cut away the backbone and the rib-bones. At the end of the belly cavity, the fish is unsupported by the block 6 and the cutters 12, 13 are moved into parallel relationship to cut on each side of the oval portion of the backbone. The machine comprises a fixed annular member 2 and a concentric revoluble ring 3 with teeth on both sides. The cutters 10, 12 are positioned in front of, and the cutters 11, 13 behind, the ring 2. Guides 4 support a slide 5 which carries the block 6 and reciprocates through the ring 2. The tail of the fish is supported on members 7, 8, on the slide 5, beneath which members a clamp for the tail may be provided. The cutter 10 is revolved by gearing 15, 16, 17 and the cutter 11 by similar gearing on the back of the ring 2. The cutters 12, 13 are journaled in blocks 20 slidable in arcuate grooves 19 in the ring and are revolved by gearing 21, 22, 23. The blocks 20 are supported by rods 28, 29 depending from levers 26, 27 which are actuated by rods 30, 31 connected to roller-ended levers 34. The roller 32 on the lever 34 associated with the rod 30 bears on the top left-hand surface of the slide 5, the said surface having a cam depression which allows the lever 26, rod 28 and block 20 to fall when the cutter 13 reaches the end of block 6 and of the belly cavity. The cutter 13 then revolves in a vertical plane to cut the tail part. The cutter is similarly angularly adjusted by a roller engaging with the left hand surface of the slide 5, the cam depression being shown in Fig. 2. The cam depressions are in staggered relationship to correspond with the staggered arrangement of the cutters 12, 13. The arrangement of the machine may be inverted, i.e., the fish may be applied to the underside of the block 6, the cutters 12, 13 then being above the fish. A rotary carrier may be used instead of a reciprocating slide, The cutters do not completely sever the fish, severance being effected after removal from the machine. The fillets are then passed to a skmning-machine.
