IPC: B41F17/14
Filed: 1922-12-19
Abstract: 204,608. Baker, G., and Baker & Co. (Rotherham), 1920, Ltd., J. Dec. 19, 1922. Die-rolling.-In a machine for stamping letters or symbols on metal tyres, hoops &c. one or more die stamps 2 are fitted to a rotary holder 1 secured by a key 7 and nut 8 to a shaft 3 which is mounted in bearings on a slidable bracket 5 and is driven from a reciprocating rack 12 engaging a pinion 11. The rack is mounted to slide in a member 13 carried on beams 14 supported by the bracket 5 and may be actuated by a pair of hydraulic cylinders. The dies and space blanks are secured against a flange 1<1> on the holder 1 by means of a retaining ring 9 and nut 10. In operation the bracket 5 is first moved aside and the tyre 15 to be stamped is placed on a plate 16 secured to a vertically movable spindle 17, rotatable in a bearing 18. The frame 5 is then positioned and the spindle 17 adjusted so that the face of the tyre contacts with a space element in the holder whereupon the shaft 3 is rotated to stamp the work. In a modification the vertical movements may be imparted to the stamping portions of the machine. In a further modification, Fig. 4, the work is supported by rollers 19 and a curved stationary plate 20, and is guided by rolls 21, 23, the latter being movable for positioning the work.

Title: Photographic processing and apparatus therefor
Inventor: KENNINGTON ARNOLD REGINALD FRA
IPC: G03D3/13
Filed: 1956-11-15
Abstract: 834,447. Photographic developing apparatus. ILFORD Ltd. Oct. 14, 1957 [Nov. 15, 1956; Nov. 29, 1956], Nos. 35026/56 and 36520/56. Class 98(2) Absorbent photographic paper having a hardened gelatine emulsion is wound between rolls during liquid processing. Preferably, the rolls are mounted in a processing tank above the level of the liquid. As shown; a length of absorbent paper carrying an exposed gelatine silver halide emulsion is processed while being wound back and forth between rolls 2, 3 through liquid 6 in tank 1 by means of a periodically reversed driving motor. Synchronous motor 29 controls cocks to pipes supplying water 13, developer 11 and fixative 16 from the main and tanks 17 and 23 respectively and to pipes 14, 12 and 15 for emptying tank 1. When tank 1 has been filled to the level 6 with either developer or fixative, the control cock, for pipe 8 is opened and the liquid removed from the tank by circulating pump 22 or 28 at the same rate at which it is supplied. Tank 17 is provided with heater 18 and tank 23 with silver recovery unit 24. Rolls 2, 3 may be mounted on a pivoted plate (Figs. 1, 2 not shown) so that the rolls can be raised clear of the walls of tank 1 for removal and replacement. Since the development process mainly takes place in the roll, the limited amount of developer carried by the absorbent paper into contact with the emulsion enables the contrast range of the prints to be reduced, thus the developer in contact with heavily exposed parts of the emulsion becomes exhausted before development is complete wheras the amount of developer is sufficient to enable the process to continue to completion in the less heavily exposed parts.

Abstract: 1,088,969. Lifting nuclear fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 5, 1966 [Aug. 13, 1965], No. 35265/66. Heading B8H. To remove a nuclear fuel element 80, Fig. 4, from a hollow nozzle 81 where it is held by balls 83 which are pushed outwards by a spring-loaded sleeve 84 a grab 1 is lowered into the hollow head of the element and latched thereto by balls 34. The balls 34 are urged outwards by a slide - block 29 which is moved up the grab by a screw 18 turned in a fixed nut 19 by an electric motor 9 and a sleeve 12. When a rod 35, which moves with the slide block 29, closes contacts 36 the motor 9 stops. After a time delay a second motor 66 is energized and pushes arms 69, 70, Fig. 4, out of slits 79, 80, Fig. 1, by rotating a differential housing 50. The housing 50 is prevented from further rotation by the arms 69, 70 when the latter are fully extended. Continued rotation of the motor 66 causes rotation of a screw 42 in a nut 43, through the differential gearing, which raises the differential housing 50 and the arms 69, 70. The latter slide up slots 79, 80 until the end of a pile of spring washers 40 abuts the lower end of rod 25. The motor 66 is now stopped by a contactor, or, if this fails, by the excess current taken by the motor. As the arms 69, 70, Fig. 4, are raised by the screw they push the sleeve 84 upwards to a position in which the balls 83 are received in grooves 90. This releases the element 80 from the nozzle 81 and since it is attached to the grab by balls 34 it may be lowered and removed.
