Title: Device for controlling the movement of a hydraulically movable machine member
IPC: B23Q5/26
Filed: 1958-05-14
Abstract: 842,198. Machine-tool details. ERNAULTBATIGNOLLES, H. May 14, 1958 [May 20, 1957], No. 15516/58. Class 83 (3). [Also in Group XXIX] A machine-tool has an hydraulically-reciprocated member 1 which is successively stopped at predetermined positions during a forward stroke by the engagement of an abutment 17 on the member 1 with axially and angularly-spaced dogs 14-16 on an indexible shaft 13. During the time that a new dog is being substituted for the preceding one, the member 1 is given a return-movement to ensure that the member cannot over-run the dog, or engage it before it is correctly positioned. To this end, liquid is permanently supplied through a line 6 and an annular channel 6a to the rod side of a piston 3 fast with member 1, and the other side of the piston is blocked, in the neutral position of a valve 8 shown, and connected to the supply-line 6 or an exhaust-line 7 according as valve 8 is moved to the right or left. When a forward selector solenoid 11 is energized, valve 8 is moved to the right by an armature 116 acting on the valve through a spring 12, and member 1 is moved forwardly until abutment 17 engages a stop. Valve 8 is fast with the shaft 13, as is also a plate 21 having recesses 22 corresponding to the angular positions of the dogs. A ball 25 co-operates with the recesses and ensures that when the shaft 13 is rotated to bring the next dog into operative position, the shaft is moved to the left and valve 8 moved to its return position. Shaft 13 is rotated by a rack 18 engaging a pinion 19 mounted on shaft 13 through a one-way drive, so that the shaft is rotated unidirectionally. A groove is provided in the plate 21, between the recesses corresponding to dogs 16, 14, to retain the valve in its neutral position when bringing dog 14 to the operative position, as the member 1 is at the end of its return-stroke at this time. Valve 8 is urged to its neutral position by a spring 20 which is weaker than the spring 12.

Abstract: 785,945. Nuclear reactors. GENERAL ELECTRIC CO., Ltd. May 28, 1956 [May 31, 1955], No. 15658/55. Class 39(4). A pressure vessel of a thermal reactor is constructed in the form of two or more shells or walls 1, 2, one within the other, the inner or innermost shell or wall 1 being arranged to contain gaseous medium under pressure and the space or spaces between the shells or walls being also arranged to contain fluid medium. Cooling gas admitted at 6 flows through the space between shells and then up through a grid 5, the reactor core 4 and an outlet 8. The outer shell 2 is thus kept cool and may be a low quality steel, welded to be leak-proof. The inner shell may be riveted or bolted heat-resisting steel, lagged to reduce heat loss. In a modification, Fig. 5, the upper part of the inner shell is supported by outlet pipes 8 with a seal 28 ensuring that the gas passes through the core. A leakage hole 31 cools the space above the core and a deflector 23 cools the bottom of the outer shell. The gas admitted to the space between shells above the core may be controlled by a valve. In a further modification, Fig. 3 (not shown), gas at an intermediate pressure cools the space between shells, so that the inner shell has to withstand a pressure difference.

[Class 29] Absorption machines and systems.-In a continuous - cycle system including an absorber formed in sections the inert pressure - equalizing gas flows through the sections in parallel circuits. The mixed refrigerant vapour and inert gas from the evaporator E, Fig. 2, passes into the upper part of the heatexchanger F and thence through the tube F<2> to the lower part thereof from which it flows into the lowest stages of the tubular absorber sections A and thence upwardly, therethrough, in counterflow to weak absorption liquor from the generators B, to the outer space F<4> of the heat-exchanger from which it returns to the evaporator. In a modification having a single generator B, Fig. 3, the absorber is also formed in sections the stages of which are alternately arranged in superposed relationship with one another. In another arrangement, having a single generator and two absorber sections, the weak liquor from the generator B, Fig. 4, passes from the vapour separator D to a vessel K and is divided by a plate L<1>, Fig. 6, into two substantially equal streams which flow through pipes K\ K<2> to the absorber sections. In a modification, the stream of weak liquor is distributed through lateral pipes M<1>, M<2>, Fig. 8, connected to a hooked supply pipe M having a stream-divider plate M<3>. In another arrangement, the weak liquor flows up a pipe N, Fig. 10, and through branch pipes N<3>, N<4> to the absorber sections. In a further modification, the weak liquor from the generator flows to a vessel P, Fig. 11, which may be the vapour separator D, and thence into the finned legs P<1>, P<2> and through the pipes P<5>, P<6>, Fig. 12, to the absorber sections. In this case, a uniform flow through the pipes P<6>, P<5> is maintained by the change of density of the liquid in the legs consequent upon heatexchange due to any variation in the rate of flow through the pipes. Specification 435,010 is referred to.
