Title: Improved control system for a double-acting fluid pressure operated servo motor
Inventor: WINSLOW KENNETH
IPC: F15B11/08
Filed: 1955-01-07
Abstract: 790,776. Pneumatic jacks. VAUXHALL MOTORS, Ltd. Jan. 5, 1956 [Jan. 7, 1955], No. 492/55. Class 8(2).. A control system for a double-acting compressed air operated jack 1 comprises a first valve 33 adapted to be actuated, e.g., manually to direct compressed air from a supply line 11 alternately to one or other of a pair of storage chambers 29, 35 through a delay throttle 31, 37 associated therewith, each chamber being connected to a second valve 19 adapted to be actuated as a predetermined pressure in the chamber being changed so as to connect the supply line 11 to one or other side of the jack piston 3. A third valve 7 which is of the fourway type as are valves 33, 19 is located between the supply line 11 and the jack cylinder 2 and is actuated to one or other of its end positions by release of pressure from control chambers 15, 16 supplied with air bled from the supply line 11. In operation and to displace the jack piston from the position shown, a valve 45 is opened momentarily to release pressure from the control chamber 43 of the valve 33 whereupon line 11 is connected through ports 39, 32 and the variable throttle 31 to the storage chamber 29, and when the pressure therein rises sufficiently, compressed air is fed to the control chamber 26 of the valve 19 to effect displacement of the valve to its other position in which it connects control chambers 44, 15 of valves 33, 7 to exhaust. Valve 7 is thus moved to a position to connect the supply line 11 through ports 10, 6 to the working space of the jack cylinder, the exhaust space thereof being connected through a line 8 and ports 9, 13 of valve 7 to a silencer exhaust 14. At the same time owing to the control chamber 44 being connected to exhaust, line 11 is connected through ports 39, 38 of valve 33 and through throttle 37 to the storage chamber 35 and after the pressure rise therein to the control chamber 27 of valve 19. Displacement of this valve to its other position releases pressure from the control chamber 16 of valve 7 through ports 21, 23 and a non-return valve 25 to the left-hand side of piston 3, resulting in the displacement of valve 7 to its other position whereby the supply line 11 is connected through ports 10, 9 and line 8 to the left-hand side of the jack piston to effect the return stroke thereof ; the other side of the piston being connected through ports 6, 12 to the exhaust silencer 14. A further stroke cannot be initiated until valve 45 is again actuated.

Title: Preparation of one component of zieglar-natta catalyst and polymerization of ethylene using it
Inventor: KORUBENOYA TARUYA
IPC: C08F4/638
Filed: 1990-01-04
Abstract: In the preparation of a supported procatalyst intended for the polymerization of olefins, particles are formed of magnesium dihalide and alcohol. The particles are reacted with an organic compound of a metal from the groups I-III, and the resulting particulate product is activated by means of a titanium and/or vanadium compound and optionally a donor, and optionally a prepolymerization is carried out for the activated particles. A problem of such a method is how to form particles of magnesium dihalogenide and alcohol having a structure advantageous for the polymerization of olefins. The problem has in the present invention been solved so that the particles are formed by spray crystallizing (spray freezing) a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol. The hydroxyl content of the particles so obtained is much greater than earlier, which results in a much more active procatalyst than the preceding ones.

Abstract: PURPOSE:To reduce a leakage current and contrive a decrease of a threshold current ad improvement in the efficiency of a semiconductor laser by forming the first semiconductor layer and the second semiconductor layer of the same conductivity type so that they may cover both ends of an active layer before forming a plurality of buried layers. CONSTITUTION:An InGaAsP active layer 2 and an n-InP clad layer 3 perform an epitaxial growth in sequence on a p-InP substrate 1 and a mesa-stripe struc ture 4 is formed by etching. Then the active layer 2 is selectively etched and a thin p-InP layer 9 is formed so that both ends of the active layer 2 may be covered by causing the p-InP layer to grow for a very short time and its structure allows the first n-InP buried layers 5 to grow. Then its structure allows the second n-InP buried layers 6 to grow and the third n-InGaAsP buried layers 7 to grow. Thus a leakage current decreases and a highly efficient buried semiconductor laser is obtained by a low threshold current.
