Abstract: 1,120,040. Nuclear power plant. BABCOCK & WILCOX CO. 24 May, 1967 [24 May, 1966], No. 24258/67. Heading G6C. In a marine nuclear power plant the pressurized water reactor and the steam generating heat exchangers are mounted in pressure vessels integral with each other. The circulating pumps, which are mounted upon, and outside of, the pressure vessels receive the primary coolant after cooling in the heat exchangers, thereby preventing cavitation and flashing. Vaporizing and superheating are effected in the heat exchangers and an electrically heated pressurizer is mounted within the reactor vessel above the core. In further embodiments, gate valves permit the isolation of defective exchanger tube banks and convection circulation of the secondary coolant is effected by an external drum connected to the exchanger and containing both water and vapour. Radioactive contamination of the secondary coolant is removed in the external drums. The exchanger pressure vessel surrounds the vertical reactor vessel at either the upper or lower ends. In one embodiment, Fig. 3, the pressurized primary coolant passes from the pumps 382, conduit 386, passage 342 to the core 326, upwardly through extension 334 to compartment 322. The heated coolant then flows through exchanger tubes 356 to the pump inlet. Secondary coolant, water, flows over the tubes 356 inside the annular space 310, 314. The container 344 forms a pressurizing space 346, heated electrically. The drums 365, in the secondary coolant circuit remove entrained moisture from the vapour and may be provided with a spray to remove radio-active particles in the event of a tube leakage.

Abstract: 758,725. Electric control systems. BRITISH-THOMSON HOUSTON CO., Ltd. Aug. 30, 1954 [Sept. 3, 1953], No. 24413/53. Class 40(1) In a system for controlling the position of a motor-driven member 5, operating for example a rheostat, which is movable to any one of a plurality of predetermined positions, at each position S1, S2, S3, a limit switch of'the stable two-position type is provided, the member 5 when moving in the forward direction (left to right), past each switch, opening the forward contacts SF and closing contacts SR, and movement of 5 in the opposite direction causing the contacts SR to open and SF to close. The field winding 2 of the motor 1 is controlled by forward and reverse relays F and R and when both are de-energized contacts F2 and R2 are closed and the motor deenergized, and when both are energized the motor remains de-energized. Energization of F opens contacts F2 and closes F1 to rotate the motor in the forward direction, and energization of R closes contact R1 and opens R2 to rotate the motor in the reverse direction. The relays are energized from conductors 6 and 7 through a normally closed push-button switch PBS a controller CS having contacts 8, 9, 10, and co-operating contacts 8a, 9a, 10a and the appropriate contacts SF or SR of the limit switches. As shown. the member 5 has been moved to its limit in the reverse direction and initially relays F and R are energized and locked over contacts FH and RH respectively. If the controller CS is actuated to say position III no change in the energization of the circuits will take place until PBS is pressed to de-energize relays F and R. Release of PBS causes relay F to be energized through contacts 10, 10a, and locked through contacts FH. When the member 5 reaches its third position S3 the limit switch closes its contacts SR to energize relay R over contacts 10, 10a to stop the motor. Subsequent movement of the controller CS followed by operation-of the push button will release the relays as before. The movable member may be driven by an oil motor controlled by electrically operated valves controlled by forward and reverse relays

Abstract: 333,396. Mackie & Sons, Ltd., J., and Mackie, J. P. Aug. 12, 1929. Coilers.--In a mechanism for filling cans 2, 3, Figs. 1 and 2, with sliver and for automatically removing the filled cans from the filling position and substituting empty cans therefor, the platform 4 which carries the cans is reciprocated alternatively along a number of tracks and is automatically transferred from one track to another. The platform 4 is reciprocated by a form of mangle-pinion mechanism comprising a vertical shaft 5 and a pinion 7 adapted to engage a rack 8 when the can 2 is being filled and a rack 9 when the can 3 is in the filling position. The pinion 7 is automatically transferred from the rack 8 to the rack 9 when the can 2 is full by inserting a third rack 38 in the gap between the racks 8, 9 to form a composite rack 8-38-9. A cam disc 22, notched at 39, is driven from the platform 4 through the levers 14, 15 pawl-and-ratchet 17, 18 and gear-wheels 19, 20. A lever 24 having a tooth 40 is pivoted at 23 above the disc 22 and is connected by a rod 26 to a crank 27 fixed on a shaft 28 which carries a second crank 31 the pin 32 of which engages a slotted arm 33 which forms one arm of a three armed member 33, 35, 38 the second and third arms respectively comprising the curved ends 36, 37 of the racks 8, 9 and the rack 38. The wheels 19, 20 are chosen so that when the can 2 is full the tooth 40 enters the notch 39, the, shaft 28 is thereby rotated and the crank 31 moved to the dotted position, Fig. 3, the ends 36, 37 being removed and the rack 38 inserted between the racks 8, 9. The pinion 7 then moves the platform 4 a sufficient distance to allow it to engage the rack 9 while the disc 22 will have rotated sufficiently to disengage the tooth 40 from the notch 39 lifting the lever 24 and thereby returning the rack 38 to its inoperative position and moving the ends 36, 37 back to close the racks 8, 9. The can 3 is then reciprocated over the range of the filling position. Single-sided racks with a reversing gear may be used instead of the double sided racks described while the platform 4 may carry more than two cans a corresponding number of racks being provided. Specification 311,556 is referred to.

Title: Improvements in or relating to television, telecinematographic and like systems
IPC: G02F1/07
Filed: 1934-08-28
Abstract: 441,505. Electro-optical light-valves. WRIGHT, E. E., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Aug. 28, 1934, No. 24812. [Class 40 (iii)] Relates to television and like receivers in which the unrectified high-frequency potentials of a modulated carrier are applied directly to a Kerr cell which, having a characteristic symmetrical about zero voltage, permits the effect of full-wave rectification to be obtained. In order to obviate the disadvantage arising, in the operation of the light-valve, from utilizing the relatively flat portion of the characteristic near the zero, and at the same time to maintain the equivalent of full-wave rectification, a constant bias is applied to the light-valve so as to carry the working region to a different part of the characteristic, viz. to each side of one of the other apices, which are much sharper than the zero apex. The value of the bias may be equal to the voltage V, which corresponds with the first maximum apex or #2V (corresponding to the second minimum apex), #3V (corresponding to the second maximum apex) and so on. Specification 375,825 is referred to.
