Abstract: 521,376. Door-operating appliances. STONE & CO., Ltd., J., and TUCKER, J. F. Nov. 17, 1938, No. 33440. [Class 65 (i)] A local control for bulkhead &c. doors normally remotely controlled, comprises a slide valve 15 which in normal position, Fig. 4, connects pressure pipe 2 through passages 6, 5, 4 to the door-closing side of the motor, and in the locally-operated position, Fig. 5, connects 2 through passages 6, 5, 3 to the door-opening side of the motor. A local operating means being capable of moving the valve to Fig. 5 position where 2 is connected to pressure and 1 to exhaust by the remote control. If 1 is put on pressure and 2 on exhaust by the remote control, and pressure acting on the end 14 of the valve added to the action of the spring 18, prevents the local control from moving the valve. The local actuating means comprises a shaft 20 extending on each side of the bulkhead 21 and carrying an arm 19 engaging the valve. On each end the shaft carries an arm 24 adapted to be moved by a lever 22, 23 through a spring 25 which is strong enough to overcome the spring 18, but not 18 plus the pressure on 14. To overcome the latter, a plug 35 is used to connect 23 to 24 to form a rigid connection with 22. Specification 29310/11, [Class 65 (i)], is referred to.

Abstract: 452,650. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Nov. 26, 1934, No. 33882. Convention date, Nov. 27, 1933. [Class 39 (i)] In a television cathode-ray tube with intensity control of the electron emission from the cathode and with an electrostatic electron lens 9, 13 for producing image points on the picture screen, distortions of the lens field by the field of at least one pair of electrostatic deflecting plates and consequent blurring of the picture near its edge are reduced by making the spacing distance, in the direction of the cathode, of the deflecting plates 14, 15 nearer the lens from the adjacent lens electrode 13 at least twice the shortest mutual distance apart of the plates 14, 15, or by making this spacing distance equal to this shortest mutual distance and in the latter case operating the plates 14, 15 in reverse phase or push-pull or giving the plates 14, 15 alternately negative potentials relatively to the electrode 13. The plates may be supplied as described in Specification 447,070, the reverse phases on the plates avoiding disturbance of the refracting field. When the plates are alternately negative and earthed, the refracting field is disturbed only in parts not adjacent to the deflected ray. To avoid trapezium distortion of the picture, the spacing between the two pairs of plates 14, 15 and 16, 17 is made at least twice the shortest mutual distance apart of the plates of either pair or at least equal to this shortest distance if both pairs of plates are operated in reverse phase. As shown, the lens reproducing an aperture in a diaphragm 8 on the picture screen is formed by a tube 9 and a large-apertured disc-anode 13 which is connected to a wall coating 18 by springs 19 attached to the disc 13. To screen the electrons moving at low speed, the tube 9 may be extended and connected to the anode 7 and a screen 12 may be provided on the cathode side of the anode 7. The control electrode is a disc 3 in a cylinder extending towards the anode 7 and surrounding the cathode 1. The leads to the plates 14 ... 17 pass through glass tubes 10, 11 supporting the plates and passing through support rings 20, 21 around the tube 9. The ray may be deflected magnetically in one direction. The electrodes are supplied from a potentiometer 5. Electrode dimensions are specified. The tube preferably contains a high vacuum. The Specification as open to inspection under Sect. 91 comprises also tubes in which the aperture of the electron lens is smaller than the distance apart of the deflecting plates and in which the spacing of the lens from the plates is at least equal to the width of a deflecting plate. Tubes and circuits described in Specifications 447,070 and 452,844 are also included. This subject-matter does not appear in the Specification as accepted.

Filed: 1968-07-17
Abstract: 1,240,192. Valves. WEBSTER ELECTRIC CO. Inc. 17 July, 1968 [18 Aug., 1967], No. 34095/68. Heading F2V. [Also in Division F1] An hydraulic valve assembly for controlling the direction and speed of a motor 16 comprises a housing 26 having an inlet passage 50 supplied by a pump 12, a priority flow passage 72 leading to the motor and receiving fluid from the inlet 50 in dependence of the size of a variable restricted orifices 68 or, 70, and an excess flow passage 62 controlled by a plunger valve 42 responsive to the pressure drop across the variable orifices. The variable orifices 68, 70 are in the form of arcuate recesses cut in the surface of a spool valve 22 having lands 22b, 22c controlling the connection between motor ports 86, 88, return ports 98, 100 and a central supply chamber 84. The supply chamber 84 receives fluid from the priority passage 72 via radial ports 78 and an axial passage 76 in the plunger valve 42. When the spool valve 22 is displaced from its spring- urged neutral position shown, flow into the priority passage is established through the orifices 68 or 70 at a rate proportional to the spool displacement. This flow is maintained constant by the plunger valve 42. The plunger has its left hand end acted upon by fluid supplied through a plunger passageway 104 from the inlet 50 and its right-hand end acted upon by fluid downstream of the orifices. This pressure differential acts on the plunger against a spring 46 and takes up an equilibrium position wherein the flow to the excess flow passage 62 is throttled by the land 42a and the flow to the supply chamber is throttled by a land 42b. If the spool valve 22 is in the neutral position shown the pressure acting on the right hand of the plunger 42 collapses through passages 106, 110 leading to outlet 102. Thus the complete pump output flows through the excess flow port 62.
