Title: Pneumatic Scram Rod Drive
IPC: G21C7/16
Filed: 1969-06-30
Abstract: 1,198,959. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 30 June, 1969 [8 Aug., 1968], No. 32910/69. Heading G6C. A pneumatic drive system for at least one control rod of a nuclear reactor comprises a high pressure tank 11 to supply scram pressure through scram valves 12 in pressure lines 13 to a common header 14 which normally is evacuated through a valve 15 in line 16 by a small vacuum pump 17, the scram valves 12 remaining closed. Only one such system is required to feed all the scram rod drives on a reactor, one such drive being indicated at 10. The vacuum produced by the pump 17 is sufficient to maintain the piston 42 in the raised position (as shown) within the closed end cylinder 35, a control rod being coupled to the piston 42 by a shaft 43. The header 14 is connected via a valve 21, a conduit 19, a passageway 31 within the reactor shield plug 25, and a conduit 41 with the top of the cylinder 35. On releasing the valves 12, high pressure gas, e.g. argon, from tank 11 is applied to the top of piston 42 which together with the shaft 43 is driven downwardly, the movement being damped by a snubber 45 and the compressed gas in the lower portion of cylinder 35. When in the raised position, the piston 42 bears against a face seal 44 to reduce leakage between it and the cylinder 35. A check valve 48 in a conduit 47 opening into the cylinder 35 permits some of the gas below piston 42 to leave cylinder 35 during the beginning of the downward stroke, thus tending to minimize rebound due to an excessive pressure buildup. Rebound is also minimized by the normal leakage past piston 42. The gas passes through the conduit 47 to a chamber 29 defined by the wide upper portion of an aperture 28 through the shield plug 25. A header 24 within the shield plug 25 provides a continuous down flow of cold argon (about 100‹ F.) around a sleeve 36 extending downwardly from the base of the cylinder 35, and through a passage 50 in this sleeve and hence around the shaft 43. This prevents hot argon and sodium vapour in the space 52 between shield plug 25 and the reactor core sodium coolant 53 from rising through the clearance space between shaft 43 and sleeve 36 and between sleeve 36 and shield plug 25. During the downward stroke the exhausted gas passes down through the sleeve 36 and out through passages 51. A baffle 54 located between passages 51 and the sodium coolant level 55 deflects the downward flow of gas. The control rods may be raised again by means of a vacuum pump 23 of larger capacity than vacuum pump 17 connected through a common header 18 to a conduit 20, a valve 22 and the conduit 19. When the piston 42 is raised to the top of cylinder 35, valve 22 is closed and valve 21 opened, vacuum pump 17 then being adequate to maintain vacuum since the piston 42 is in contact with face seal 44 with very low leakage. The valves 12, 15, 21, 22 are all of the solenoidactuated type.

Title: Slide valve arrangement for hydraulic gears
IPC: F16H61/40
Filed: 1936-12-04
Abstract: 481,686. Radial cylinder pumps. BISCHOF, B. Dec. 4, 1936, No. 33285. [Class 102 (i)] [Also in Group XXIX] In a hydraulic gear comprising pump and motor of the piston type and rotary slide distributing valves, the latter are so connected to the elements determining their rotation (that is, constraining them against rotation or causing them to rotate) that the valves are prevented from rotating relatively to said elements but are free to move laterally so as to adapt themselves to the wall of the bearing sleeve in accordance with the pressure of the liquid acting thereon, and in addition are capable of shifting freely in the axial direction. The pump valve 3, Fig. 1, working in a bearing sleeve 4 in the casing 5, is constrained to rotate with the pump shaft 1 by a coupling 2, Fig. 3, comprising a ring provided with grooves 6, 7 engaged, with radial play, by dogs 10, 11 on the slide valve and with grooves 8, 9 engaged, with radial play at right-angles, by dogs 12, 13 on the shaft 1 ; alternative forms of coupling are described; alternatively the connection may be effected by a flexible shaft. The packing for the valve is such as to permit the lateral movement of the valve ; in Fig. 1, the rubbing collar packing 28,31, 32, 33, 34 has radial clearances 35, 36; in a modification, Fig. 8, the rubbing collar 32 can adjust itself on the spherical part 28a of the sleeve 28 mounted on the valve 3; alternatively the sleeve 28 may be flexible. A ring 37, Fig. 1, limits axial movement of the sleeve 28. The motor valve 38, Fig. 1, is rigidly connected to a spindle 39 the outer free end of which is constrained against rotation by a coupling 42, 43 shown in detail in Fig. 10, and allowing lateral and axial movement of the valve 38. A counterweight 55 and lever system are provided to absorb jolts on the valve 38. The part 43 is hollow to constitute an air chamber 53 which communicates by a bore 54 in the spindle 39 with the pressure chamber 29 surrounding the valves, this arrangement serving to compensate kicking effects produced by periodic variation of the amount conveyed by the crank drive in the pump and motor. The valve 3 is connected. by a rod 64 with a threaded member 67 prevented from rotation and engaged a threaded member 66 prevented from moving axially relatively to the valve 38 and rotatable by levers 69 so that the two valves 3, 38 can be drawn tightly together or forced apart to stop the transmission. The screw-and-nut mechanism is free to move axially relatively to the fixed casing, so that the two valves can jointly move axially. The stub shaft 73 of valve 3, Fig. 11, is of smaller diameter than the stub shaft 74 of valve 38, so that the valves are urged to the left against a spring load 78 by the pressure of the liquid ; the valves are provided with oblique control edges 79, 80 so that automatic regulation is thus effected.
