Title: Improvements in or relating to nuclear fuel
IPC: G21C21/02
Filed: 1961-09-20
Abstract: 949,727. Nuclear fuel. GENERAL DYNAMIC CORPORATION. Sept. 20, 1961 [Sept. 30, 1960], No. 33737/61. Heading G6C. Ceramic nuclear fuel elements are formed from a particulate ceramic fuel having an average particle size of 150 microns or greater e.g. an oxide, carbide or silicide, preferably uranium oxide, by mixing it with a refractory material, e.g. an oxide carbide or silicide, preferably Al 2 O 3  or BeO, to form a fuel body and sintering. The refractory material can be either a matrix in which the fuel particles are uniformly distributed, a coating on the individual fuel particles, or a coating on a previously compacted fuel body. The powdered fuel is formed into particles of desired size by mixing with a binder and suitable solvent, e.g. polyvinyl alcohol and water, into a paste, drying e.g. at 100-130 F., compressing at 10,000-20,000 p.s.i., crushing and sieving through a sieve of appropriate size. These fuel particles may then be mixed into a paste of the desired refractory material in a binder and suitable solvent e.g. paraffin and carbon tetrachloride, care being taken that this solvent is not a solvent for the binder of the nuclear fuel. The mixture is sieved, dried, compressed at 10,000-30,000, p.s.i. and finally sintered in hydrogen. Alternatively the fuel particles can be immersed in a slurry of the refractory material in an appropriate binder and solvent. The particles are then dried and reimmersed until a satisfactory coating is built up. when the particles are compacted and sintered as above. In a similar process the uncoated particles are first compacted and the body produced sprayed with a slurry of the refractory material to produce the desired coating. It is suggested also that coated and uncoated fuel particles are used to produce the fuel body provided that in the finished form the coated particles are on the surface of the body and can thus provide the desired protection.

Title: Machine for washing and drying clothes
IPC: D06F17/12
Filed: 1946-11-13
Abstract: 626,227. Washing-machines. RASMUSSEN, C. O., (trading as SIMPLEX). Nov. 13, 1946, No. 33742. [Class 138 (ii)] [Also in Group II] A machine for washing and drying clothes comprises a hydro-extractor drum 18 adapted to be removably mounted in the cylindrical casing 1 of the machine and provided with a number of radial vanes 19 which are disposed internally around the rim of the drum and in line with the discharge from a centrifugal blower 5 mounted in the lid 2 of the casing for causing rotation of the drum. The blower 5, which is driven by an electric motor 3, is partly enclosed by a plate 7 which is secured to the lid 2 and provided with a central conical depending portion 8. For use in washing, a cylindrical drum 10 is inserted in the casing 1 (as shown in the right-hand side of the drawing), the drum being provided with a removable lid 11 bearing on its upper edge. During washing, an air current from the blower 5 passes through apertures in the portion 8, downwardly in the space between the drum 10 and casing 1, and upwardly through the interior of the drum for discharge through one or more openings 13 in the lid 11 ; an apertured deflector plate 24 may be mounted below a central opening 13 in the lid. When the machine is to be used for drying, water is drained off through a cock 14, and the drum 10 is replaced by the drum 18 (as shown in the right-hand side of the drawing), which is rotatably mounted on a bearing 17 provided at the upper end of a pillar 15 fitting into a loose tripod 16 placed on the base of the casing 1. The air current from the blower 5 then passes from the vanes, downwardly in the space between the drum 18 and casing 1 and upwardly into the drum through holes 21 in the inner wall 22 thereof ; alternatively, the air current after striking the vanes may pass either downwardly into the drum or both in this direction and into the space between the drum and casing. A wire-mesh screen may be provided on the inner side of the vanes to prevent clothing from contacting the latter. The drums 10, 18 are so dimensioned that, for storage, one may be inserted in the other within the casing 1. Specification 625,813 is referred to.

Title: Safety device for power operated machines
IPC: F16P3/08
Filed: 1972-07-19
Abstract: 1393283 Bending press BLUE STAR ENG Ltd 19 July 1972 33860/72 Heading B3E [Also in Division F2] Power operation of approachable members is prevented until the space between them has been reduced to less than finger thickness by ancillary mechanism. More specifically, a bending, punch or stamping machine has a movable punch 11 which is manually movable to gently lower the punch 11 to approach a workpiece 3 to within a distance less than the operator's finger thickness after which a hydro-pneumatic power transmitting mechanism can be operated to drive the punch with full force, the arrangement providing a safety device for preventing injury to the operator without the necessity for the usual cumbersome guards &c. As shown the punch 11, carried by a top bridge member 12, co-operates with a die 13 on an anvil 14 fast with the machine frame, the top member 12 being linked by tie rods 15 to a bottom bridge member 16 located below the anvil 14 through which the tie rods 15 pass. A manually adjustable cam rod 17 is located in a channel in the under surface of the anvil 14 above a pressure block 18 also located in the channel. Hydraulic rams 19 mounted on the bottom member 16 bear against the block 18. The arrangement is such that manual solution of the cam rod 17 via a lever 2 carries the block 18 to rise or fall within the anvil channel, the ram 19, members 16, 12, tie rods 15 and panels 11 being thus manually movable up and down as a unit under the control of lever 2, the unit being upwardly biased by springs (not shown). The extent of movement given to the block 18 and hence punch 11 by manual rotation of the cam rod 17 via lever 2 effectively gently reduces the press loading clearance i.e. the clearance for placing, or removal, of the workpiece on the die to a close proximity clearance over the workpiece less than finger thickness i.e. “ inch or less. When the clearance has been thus reduced, the cam rod 17 additionally closes a safety switch A allowing pressurized air to pass to an operating switch 4 which may be momentarily depressed by the operation to signal a shuttle valve B to allow pressurized air to an hydro-pneumatic intensifier 5 which hydraulically pressurizes the rams 19 for full operation of the punch 11. A manually adjustable regulating valve C controls the effective working pressure of the rams 19. Repeated operation of the punch 11 when in the close proximity position may be effected by repeated momentary depression of the switch 4.

Title: Sawtooth waveform generator
IPC: H03K4/12
Filed: 1954-11-23
Abstract: 754,321. Sawtooth voltage generator circuits. GOODYEAR TIRE & RUBBER CO. Nov. 23, 1954 [June 24, 1954], No. 33877/54. Class 40 (6). Fig. 1 shows a sawtooth voltage generator circuit in which due to the anode voltage of discharge-tube 1 being at a lower potential than the screen-grid a secondary-emission current flows from the anode to cathode via resistor 5. The control-grid potential is thus negative with respect to cathode so that capacitor 7 charges through resistor 6. As the capacitor 7 charges the control grid voltage and the secondaryemission current flow through resistor 3 increase exponentially, Fig. 2. At the same time the current flow through resistor 3 to the screengrid due to the control-grid voltage rise in. creases exponentially in such a direction that the total current flow in resistor 3 increases linearly with time. When the voltage rise at the control grid due to capacitor 7 charging is such that control-grid current flows, capacitor 7 is rapidly discharged so that a sawtooth voltage is generated across cathode resistor 3. The repetition frequency may be controlled by variation of resistor 6 or by changing the value of capacitor 7. The capacitor 7 may be omitted and its function replaced by the inter-electrode capacity of tube 1.
