Title: Nuclear reactor installations
IPC: G21D3/08
Filed: 1961-02-10
Abstract: 915,383. Nuclear power plant. SULZER FRERES S.A. Feb. 10, 1961 [March 3, 1960], No. 5148/61. Class 39 (4). The reactor 1 is cooled by superheated steam circulated through the reactor and the heat exchanger 3 by the blower 5. Superheated steam generated in the secondary side of 3 is circulated through the turbine 8 by the pump 13. The steam from 8 is condensed at 10 and supplied to tank 12. The radioactivity of the steam leaving the reactor is measured by the detector 24. The latter controls valve 23 to remove steam from pipe 2 in accordance with its radioactivity and passes it to tank 12 through the turbine 25 and purifier 28. A fall in pressure at the primary coolant circuit C is detected by the pressure-sensitive device which controls valve 21 regulating the flow of steam into the primary circuit from the secondary circuit at 7.

Title: Improvements in refrigerating apparatus of the absorption type
IPC: F25B15/10
Filed: 1927-02-25
Abstract: 296,110. Maiuri, G., and Bossini, R. F. Feb. 25, 1927. Refrigerating, absorption machines and processes for.- In a continuous-cycle system containing a pressure - equalizing inert gas, the refrigerant is generated from solution at low temperature in a refrigerator 4 to produce the cooling effect, and circulates also through two absorbers 3, 7 and a high temperature generator 1 without undergoing condensation. The liquor spaces of the absorbers are in communication and the liquor has a connected single circulation through the system. The generator 1 may be heated by an electric heater 18 and the evolved refrigerant vapour passes through a water cooler 2 to the absorber 3. The liquor flows from this absorber through a pipe 5 to the refrigerator 4, and returns in a. weaker state through a pipe 6 to the generator 1. The inert gas is circulated by being heated in a pipe 8 in the generator 1 and cooled in a pipe 9, and the mixture of inert gas and refrigerant vapour flows from the refrigerator 4 to the other absorber 7. Liquor flows from the generator 1 by a pipe 10 to the absorber 7, and the pipes 10, 5 form heat exchangers with. the pipe 6. If desired a shunt pipe 11 may extend from the absorber 7 to the pipe 6 to increase the liquor circulation locally. The inert gas may be the residual air of the apparatus, or helium, hydrogen, nitrogen or argon, and the system may operate at atmospheric pressure. A modification is described in which a fan and liquid pump are employed and are driven by a motor enclosed in the system, as in Specification 296,109. In this arangement the inert gas exchanges heat with the gas mixture from the refrigerator, and air-cooling is employed. Specification 13875/09 also is referred to.

Abstract: 407,186. Grinding valve-seats. JOHNSON, G. W., 47, Lincoln's Inn Fields, London.- (Hall Manufacturing Co. ; Toledo, Ohio, U.S.A.) Feb. 28, 1933, No. 6074. [Class 60.] A valve-seat grinding tool particularly for grinding the valve seats of internal-combustion engines is fitted with a pilot stem 10, Fig. 1, adapted to engage in the valve-guide, and the rotary grinding-wheel spindle 12 is driven from an electric motor 23 mounted eccentrically of the grinding spindle in a housing 25 rigid with and forming part of the tool. The stem 10 may be centred and secured in the valve guide by an upper tapered member coacting with a tapered nut threaded on the lower end of the stem. The grinding-spindle 12 carries a wheel 14 and encloses an inner shaft 11 which is eccentrically bored to receive the upper end of the pilot stem so that the grinding-wheel is eccentric to the axis of the pilot. The grinding-spindle is driven at high speed from the motor spindle 16 through gears 17, 18, and the shaft 11 is slowly rotated to give the wheel a planetary motion round the seating by worm gearing 19 shaft 20 and further worm gearing 21. The motor housing is secured by bolts 26 to the grinding-spindle housing 13 and a fan 24 is mounted on the shaft 16 for cooling the motor. The grinding pressure is regulated by a gauge rod 29 engaging the upper end of the pilot stem and secured to a screwed sleeve 30 threading on to a member 31. A handlever 32 extending from the tool housing engages a vertical spring pressed rod 33 so that the overhanging weight of the motor may be counterbalanced by the operator. In a modification, Fig. 2, the grinding-spindle 33<a> is eccentrically mounted with respect to the pilot stem 10<a> and is driven from the motor 38 through gears 35, 36. The pilot is mounted in a member 39 which may be rotated in the housing 34<a> to vary the offset of the grinding- wheel. A screw 42 adjusts the position of the tool, which is turned by hand to cause the grinding-wheel to travel around the valve seat.

Apparatus for the reversed-lay stranding of insulated wires for communications cables comprises supply bobbins (not shown), a guiding face plate 3 for aligning the wires, an accumulator 1, rotating in a fixed sense at a constant speed n, an oscillating roller 2 having two groups of rollers, one group movable relative to the other to vary the draw-off speed and give twists to the wires which reverse in direction of lay for every length I accumulated in accumulator 1, and a constant speed take up device (not shown). Several accumulators (1, Fig. 5, not shown) may be installed in series to decrease the lay length. A plurality of stranding units may be run in parallel, and the resultant strands passed to a further series unit, for assembling into a cable (Fig. 6, not shown). Constant pay-off speed is maintained by an inverse oscillating roller (111, Fig. 7, not shown) similar to oscillating roller 2, but inserted before the accumulator (114) and synchronized in opposition to the first oscillating roller. Adhesive, from a coating head (117, Fig. 7, not shown) protects those portions of the strand where the lay is reversed. A buffer (Fig. 10, not shown) comprising rollers (135) on fixed axes and a spring-controlled, vertically movable roller (136), is inserted between the inverse roller (111) and assembling dies (112) to compensate time differences between reversals of the oscillating and inverse rollers.
