Title: Improvements in or relating to valve control means
IPC: F16K31/48
Filed: 1930-08-12
Abstract: 359,100. Water gas generation. PINTSCH, AKT.-GES., J., 71, Andreasstrasse, Berlin. Aug. 12, 1930, No. 24170. Convention date, Aug. 22, 1929. [Class 55 (i).] An automatic valve control for use in connection with water gas generation is arranged so that the relative order of opening and closing of the main valves is determined by the arrangement of the ports in a control valve seat, and the disposition of annular passages in the control valve member and the time during which each main valve is open or closed is controlled automatically by means including inter alia a time-controlled tappet-wheel. In the form shown in the Figures the control valve 7 is in the form of a rotary disc valve having a series of segmental annular recesses 9 communicating with one another through holes 11 and with a circular recess 10 in communication with a corresponding recess in the valve seat 8 connected to the exhaust pipe 10<1>. Oil under pressure is fed into the chamber 12 and passes thence through any of the ports in the seat outside the valve member to close the main valves connected to the respective ports. The ports within the valve member being connected to exhaust permit the connected main valves to open. The series of recesses may be replaced by a single recess shaped to the envelope of the series. The control valve is periodically moved by an electric motor acting through a reciprocating rod 15 and a triangular pawl engaging a ratchet wheel 29 having both internal and external teeth. The position of the pawl, which may be moved by hand, is normally determined by adjustable tappets 27 on a disc 26 engaging one or other of the projections 22, 23 on a rocking lever 20 secured to the pawl. The wheel 26 is slowly rotated by a ratchet gear operated by the rod 15 or may be rotated through gearing driven by the motor.

In a haymaking machine as described in parent Specification the operating lever is fixed to a spindle 19 which is rotatably supported in a tube 6 which itself is rotatably supported in a tube 9 of the rake head. The spindle 19 may slide longitudinally, so disengaging the roller from the curved track, and may rotate to reposition the operating lever for rotation of the rake head in an opposite sense. After rotation, the spindle 19 is pushed back to engage the roller with the curved track. Both positions of spindle 19 relative to the tines are lockable for which purpose a common pawl 21<SP>1</SP> pivoted at 20 on the tine carrier plate 3 engages one of two notches spaced 90 degrees apart on a plate 22 fixed to rod 19. To prevent accidental rotation of the tine carrier plate in making this adjustment, a bar 27 engages a notch 28 on an extension of the fixed tube 9. Alternatively the common pawl may itself engage notch 28 (Fig. 7, not shown). In other modifications two operating levers per arm are provided for selectively connecting the tine plate to the curved track. Fig. 8 shows two levers that form the limbs of a common arm 35. It is pivoted at 34 and adjustable by rotating block 36 via rod 37. In another modification, the pivot point 34 is offset from the centre line E. In a further modification both operating levers are designed to engage the track permanently, a shift rod carrying a locking member being provided to selectively engage slots in the ends of the operating levers proximate tube 6. To enable a positive engagement of the rollers with the track, a cylindrical curved surface or corresponding ring forming part of a sphere is positioned flush with the outer edges of the track. The tines are grouped on the carrier plate in such a way that, no matter in which sense the head is rotating, the tines are subject to similar type stresses.

Title: Improvements in and relating to control arrangements for electric switches
IPC: H01H33/30
Filed: 1938-08-26
Abstract: 504,532. Slow-closing valves. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 26, 1938, No. 25140. Convention date, Aug. 30, 1937. [Class 135] An arrangement for controlling the actuation or the blowing or both of electric switches by a pressure gas in which the control impulse is prolonged a predetermined time comprises a control valve 1 which is opened to allow the passage of pressure gas by a control impulse applied for example manually or electrically and a piston 11 exposed to the pressure gas passed by the valve so as to complete the opening movement, the opening period of the valve being terminated by the subsequent equalization of pressure on the two sides of the piston. As shown in Fig. 1, the spring- pressed valve 1 controlling the passage of gas between a supply conduit 5 and a conduit 6 which passes gas to the switch for blowing or actuating purposes is operated by a lever 21 which is given an initial impulse by a push rod 25 or by an electromagnet 26. The piston 11 is coupled to the lever by a rod 22 and has a small bore 14 which restricts the passage of gas between its upper side and a chamber 30 on its under side. The piston cylinder 12 communicates with the valve outlet chamber by a conduit 10 which may be extended by a pipe 13 to a point near the valve. The bore 14 may be replaced by a passage in the cylinder 12 and may be adjustable. The valve stem 23 also carries an exhaust valve 27. In the modification, Fig. 3, the piston 11 and the valve 1 are arranged coaxially, the valve being opened initially by the impulse of the electromagnet 26 on the piston rod 23. The latter has a passage 34 which connects the upper piston chamber 37 with the valve outlet. The piston may be loose on-the piston rod and engage a collar thereon.
