Title: Process for reprocessing nuclear fuels
Inventor: WURM JOSEPH GERARD
IPC: G21C19/48
Filed: 1965-06-08
Abstract: Spent ceramic uranium oxide nuclear fuel is digested with a molten basic alkali metal compound in the presence of an oxidizing agent to form insoluble alkali metal uranate which is separated, leaving fission products and other impurities in the melt, the uranate is reacted with a melt of aluminium halide or sulphate or alkali metal or ammonium hydrogen sulphate or pyrosulphate to form a uranyl salt and the uranyl salt is reduced to UO2. Irradiated UO2 fuel elements canned in stainless steel are cut into pieces and agitated in a NaOH melt containing sodium peroxide; nitrates and carbonates may also be present.  After passing through a coarse sieve, solid sodium uranate is removed by centrifuging or filtering through porous graphite; Mo and Nb remain in the melt with fission products but Pu follows the U. The melt is treated with Al2O3, SiO2 or other oxide to form insoluble fission product compounds. The sodium uranate is reacted with a melt of K2S2O7 or AlCl3 to form uranyl sulphate or chloride; finely divided Al2O3 forms in the mixture or is added thereto and serves to remove the remaining fission products as an insoluble deposit. Reduction of the melt to UO2 is effected with NH3 or H2.  To purify the UO2 further, the process may be repeated.  Uranium carbide fuel may be converted to oxide and treated by the same process. missing page 92

Title: Improvements in and relating to automatic motor vehicle break mechanism adjusters
IPC: F16D65/56
Filed: 1953-09-07
Abstract: 721,133. Brake adjusting devices. FORD MOTOR CO., Ltd. Sept. 7, 1953 [Sept. 6, 1952]. No. 24706/53. Class 103 (1). The invention relates to an automatic adjustment device for the brake mechanism of a motor vehicle, particularly such as is fitted to the automatic transmission gear thereon. The brake band 13 is applied to the shaft or drum 12 by a fluid pressure operated piston 24 which acts through a lever 34 pivoted on pin 32. The piston rod 26 thrusts against one end of an adjusting screw 36 threaded into one end of the lever 34. The other end of the screw 36 is reduced in diameter and carries a compression spring 46 which abuts a shoulder 47 on the inside of a ratchet member 39 The cylindrical extension 38 of the screw 36 has a pin 44 projecting radially on each side through inclined slots 43 in the ratchet member 39. If, when the brake is applied, the screw 36 is caused to move a certain distance axially, the co-action of the pin 44 with slots 43 in the ratchet member 39, which cannot move axially due to its abutment with a stop member 63, causes a rotation of the ratchet 39 which may be sufficient to make a pawl 51 carried on a parallel pin 52 move to the next tooth. When the brake is released, the compression spring 46 causes a corresponding rotation of the screw 36 in the lever 31 which adjusts the brake.

Title: Mode selecting devices for tepe recording and/or reproducing apparatus
IPC: G11B15/10
Filed: 1974-06-05
Abstract: 1450280 Tape recorder mode selector SONY CORP 5 June 1974 [9 June 1973] 24978/74 Heading G5R In a tape recorder mode selecting arrangement in which movement of a pushbutton to select a mode closes switches in a circuit for energizing a solenoid which moves the required actuating members to establish the mode, a delay is incorporated in the energizing circuit whereby if a second pushbutton is operated during the delay period only the mode selected by the second pushbutton is established. Operation of one of the pushbuttons 1-3, e.g. pushbutton 1 for normal forward mode, moves a corresponding slide 5 downwards against the action of a spring 9 until a part 5a of the slide, which pivots latching plate 10, enters locking aperture 10a of the plate and allows it to pivot back to its initial position. During this oscillation of the locking plate a switch S1 is momentarily closed. The downward movement of the slide 5 also moves an elongated slider 13 to the left to operate switch S2 and moves a transmission member 15 into a horiziontal position in which a downward projection 15a thereon can be engaged and driven by an arm of a bell crank lever 18 which is rotated via rod 20 when solenoid P is energized. Solenoid P is energized, Fig. 2, when capacitor C1 charges to a sufficient level to bias on a transistor TR1. Capacitor C1 is discharged via the emitter-collector path of transistor TR2 when switch S1 is momentarily switched on by the oscillation of the locking bar and is then charged via resistor R1 after movement of slider 13 actuates switch S2. Movement of the transmission member 15 by the solenoid moves the recorder head and drive members to establish the normal forward mode of operation of the recorder. The slider 13 includes an abutment 13b which when the recorder is switched to fast forward or rewind by operation of one of pushbuttons 3 or 2 is disposed below slide 5 to prevent actuation of the recorder to normal forward mode. In a cassette recorder a further switch operated by the presence of a cassette can be incorporated in the supply to the delay circuit C.R. to prevent recorder operation in the absence of a cassette and a further switch can be incorporated to prevent the normal forward mode of operation being established when a pause control is operated. This pause control, Fig. 4, not shown, acts to remove the drive to the take up reel and to move the pinch rollers away from the two drive capstans provided.
