Title: A Steam-Cooled Nuclear Reactor, Especially of the Epithermal or of the Fast Type
Inventor: BOGAARDT MAARTEN
IPC: G21C3/58
Filed: 1967-03-30
Abstract: 1,174,796. Controlling reactors. REACTOR CENTRUM NEDERLAND. 30 March, 1967 [31 March, 1966], No. 14616/67. Heading G6C. In a wet-steam cooled epithermal or fast reactor an abnormal increase in reactivity, caused by an increase in the volume of water in the core, is prevented by a resonance neutronabsorbing material incorporated in the fuel material. The added material is a thermal and/or epithermal absorber and the fast or epithermal neutrons are moderated by the water to an energy level at which absorption occurs. The entry of water into the bore tends to raise the reactivity by reducing the neutron leakage. Steam and water are admitted at the apertures 10 and 16 respectively. The water flows upwards over heat shield and downwards into chamber 24 where it enters the atomizer pipes, 5 with the steam from chest 9. The wet steam flows upwards through the pipes 2 containing the fissile elements. The heated steam leaves the pressure vessel through aperture 18. The upper end of each tube 2 is supported resiliently. The added absorber may be boron, godolinium, samarium, hafnium or dysprosium.

Abstract: 113,923. Corley, Q. D. Oct. 11, 1917. Limbs, artificial.-The fingers are adjustable into several positions by forming grooves 5 in their bases, into which a transverse loclcing-bar 6 is pressed by a spring 10. The bar can be retracted bv a cord 12. The thumb is pivoted on a stud 15 which carries a pulley segment 22 receiving the operating cord 23, and it is locked in the closed position by means of the ratchet 18 and pawl 19. For releasing the thumb, the cord 23 passes round a pulley 24 mounted on a dog 28. Tension of the cord causes the lip 33 of the dog to rotate the ratchet-wheel 29 and thereby the hexagonal cams 30 which depresses a sliding anglebar 31 having a shoe 32 bearing on the pawl 19. The pulley 22 is now free to be retracted by the spring 27 on relaxing the cord, the dog 28 riding back over the rack 29. In a modification, the fingers can be operated by a mechanism similar to that of the thumb.
Patent GB-1008661-A (GB)
Title: Method of repelling water from a transparent member
IPC: G11B15/58
Filed: 1963-07-16
Abstract: A method of producing a water-repellent coating on a transparent member comprises applying a solution of a compound of the formula <FORM:1008661/B1-B2/1> to the surface of a transparent member having surface donor sites and permitting the solvent to be removed from the solution.  The process is applicable to glass and to transparent plastics materials.  A donor site is defined as a position available for acceptance of a water-repellent substance, especially such as an anionic charge site and also a hydrogen bond site or an acidic site. The solvent used for making the solution may be aqueous or non-aqueous.  The solution may be applied to the surface by spraying, rubbing or splashing.  The process is particularly applicable to keeping the windscreens of aircraft and boats clear during periods of rain.  During prolonged rain the applications are repeated at intervals of from 15 seconds to about one minute.

Abstract: 464,236. Converting. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. May 25, 1936, No. 14773. Convention date, July 16, 1935. [Class 38 (ii)] The " make alive " electrodes 9 of the valves 5 in a converting arrangement are supplied from the secondary windings 18 of transformers 17, the primaries of which are connected across the main valves through vapour electric discharge paths. In the form shown, a multi-anode discharge device 20 is used. The device 20 may be grid-controlled, the grids being supplied through a phase-shifting transformer 31 so that the moment of ignition in the main valves 5 may be controlled. Preferably, two sets of transformer windings 16, 18 are mounted on a single core and are connected so that the core flux is alternating. In a modification, the auxiliary valve 20 is replaced by auxiliary anodes mounted in the main valves 5,the connections being arranged such that the auxiliary anode circuit of one valve controls the make alive circuit of the adjacent valve. In this arrangement, to enable starting to be effected initially, one of the auxiliary anodes is connected to the cathode through an auxiliary valve and switch. By closing the switch temporarily, a current impulse is allowed to flow sufficient to start a main discharge device.

Abstract: 1,033,972. Rolling. UNITED ENGINEERING & FOUNDRY CO. April 17, 1964 [April 17, 1963], No. 15024/63. Heading B3M. [Also in Division B6] Apparatus for guiding strip along a given path includes a pair of rollers, each having a portion which at least partially supports the strip, and a projecting portion, formed by a collar, which guides one edge of the strip. Although applicable to guiding strips of paper, rubber and plastic, Fig. 1 shows a roller table 9 following a rolling mill for hot metal strip, a coiler being situated to the left of the table. The strip is guided by longitudinal edge guides 13 and 14 and driven guide rollers 25 and 26, before coiling. A second roller table 49 for another coiler follows the first coiler. Both longitudinal guides and guide rollers are laterally adjustable. A motor 15 drives spindles 16 to move the guides 13 and 14 together or apart, the spindles (Fig. 2, not shown), having oppositely threaded portions 17 and 18 on which the guides are mounted. The roller 26 is attached by an arm 39 to the guide 13 and is thus adjusted with it. The roller 25 is adjusted by a screwed spindle which is also driven by the motor 15. After all the guides have been set for a given strip, the roller 25 and guide 14 are temporarily moved away from the guide 13 to allow for an enlarged end of the strip to pass the guides. The strip is urged against the guide 13 by the skewed, independently driven rollers 11. Cylinders 23, each actuating a Hall crank-lever, move the guide 14, while a cylinder 42 moves the roll 25. During coiling a kind guide roller, situated above and between the rollers 25 and 26, is lowered to urge the strip against the latter rollers. The collars on the rollers could be replaced by movable collars on a single roller.

[Class 40 (vi)] A circuit for effecting the detection and amplification of the combined video and synchronizing signals in a television receiver without losing the D.C. component, comprises a leaky-grid detector circuit D.C. coupled to a video-amplifier stage which is D.C. coupled to the modulation electrode of the cathode-ray tube. In the Figure, a television signal at R.F. or I.F. is applied to a leaky-grid detector valve 3 which is directly coupled to the videoamplifier stage 10, appropriate bias for this stage being obtained from the auto bias circuit 7, 9. The output from valve 10 is directly coupled to the cathode of the cathode-ray tube 11, the grid of which is maintained correctly biassed by potentiometer 12. The signal from potentiometer 5 is applied to conventional sync.-separating circuits SS. The component values of the auto-bias circuit 7, 9 and of the decoupling circuit 6, 8 are so chosen that the D.C. component is passed substantially unaltered. In a modification, Fig. 2 (not shown), for use with television signals in which zero signal amplitude corresponds to peak white picture and where the synchronizing signals are of greater amplitude than black picture level, the grid of the cathode-ray tube is directly coupled to the video-amplifier stage, the cathode of the cathode-ray tube being maintained at a correct potential by means of a potentiometer across the receiver's H.T. supply.
