[Class 86] A device for dosing a flowing liquid with a reagent comprises a tipping measuring device for the reagent, adapted to be charged automatically and released by solenoid-operated means when sufficient liquid has flowed. A tipping vessel 10 is pivoted at 11 to receive reagent flowing through pipe 13 into a pivoted funnel 14. In the charging position, shown in dotted lines, the funnel 14 is held in place by levers 16 on the vessel 10 co-acting with pivoted bell-crank levers 18. A catch 19 comprising a disc 24 having a detent 25, a stop 29 and a freely pivoting member 28 is engaged by a latch 22 operated by a solenoid energised at intervals by the flowing main stream of liquid by means of a meter or like device. The rotatable member 28 is engaged by a rod 30 on the vessel 10 when charged, and is prevented from anticlockwise movement by the stop 29. In this position the funnel 14 discharges into a storage space 20 in the tank 12. On energisation of the solenoid, the catch 19 pivots and allows the vessel 10 to take up the position shown in chain lines, where the reagent is discharged into the main stream of liquid through pipe 23. The vessel 10 then returns to the position shown in dotted lines. A time delay switch may be provided in the solenoid circuit to open the circuit after a predetermined interval should the circuit remain closed. Specification 607,433 is referred to.

Title: Improvements in or relating to fluid pressure supply systems, particularly for operating vehicle brakes
IPC: B60T13/58
Filed: 1954-02-22
Abstract: 747,216. Compressed air brakes. BENDIXWESTINGHOUSE AUTOMOTIVE AIRBRAKE CO. Feb. 22, 1954 [March 4, 1953], No. 5201/54. Class 103 (1). [Also in Group XXVIII] In a compressed air brake system comprising a pneumatic servo-unit 14 of which the diaphragm 64 has a pressure chamber 62 on one side and a non-pressure exhaust chamber 76 on the other side, the exhaust chamber 76 is connected by a pipe 20 to the suction side of a reciprocating pump 10, which maintains a reservoir 12 at a constant pressure for operating the servo-unit 14. By using a continuously running compressor 10 having a clearance volume above the piston which gives a steady compression of about 100 pounds per square inch, it is found that such a system is simpler and less costly than one using unloading and governing mechanisms for the compressor. Water is discharged from the system by so actuating the servo-unit as to produce a supercharging of the compressor suction so that the delivery pressure exceeds the normal value and any liquid in the reservoir 12 is ejected through a sump filter 90, pipe 88, and loaded diaphragm release valve 96.

Title: Improvements in Aircraft Control.
Inventor: COOPER ARTHUR QUILTON
IPC: B64C1/00
Filed: 1918-04-02
Abstract: 131,043. Cooper, A. Q. April 2, 1918. Steering and balancing. - A manual and servo-motor control for any movable part, particularly for use on aircraft, comprises a servo-motor which is controlled by variations of tension in the cables used for operating the part manually. Means may be provided to ensure that the manual effort required is proportional to the displacement of the movable part. Means for disconnecting the servomotor to permit of direct manual control may be provided. Fig. 3 shows an aircraft control in which two friction wheels 2, 3 geared to rotate in opposite directions are driven continuously by a windmill 1. The cables 8, 9 from the manual control are passed around pulleys 10 and are equally deflected from the straight line by pulleys 6, 7 on a lever 4 pivoted to the servo-motor frame. The other ends of the cables are connected to the part to be operated. Movement of the manual control produces differential tension in the cables 8, 9, and the lever 4 is displaced, thereby bringing a friction wheel 11 into engagement with one or other of the wheels 2, 3. The spindle of the wheel 11 drives a worm-wheel 12<1> coupled to a sprocket 13 around which is passed a length of chain connected by cables 14, 15 to the cables 8, 9, so that the pilot is assisted by the servo-motor. Two stout sections of elastic 18, 19 are connected to the cables 14, 15 and to the servo-motor frame, and are deflected by pulleys 16, 17 on the lever 4. Movement of the manual control tensions one or other of these elastic sections in proportion to the displacement, and when the control is released, the position of the lever 4 is reversed and the parts restored to normal position. A modification without the elastic sections 18, 19 is described, the action of the servo-motor tending to equalize the tensions in the cables 8, 9. A clutch device controlled by the pilot removes the sprocket 13 from engagement with the worm-wheel 12<1> and shoots a bolt to hold the lever 4 in midposition when desired.

IPC: H01J13/16
Filed: 1955-02-28
Abstract: 805,095. Metal-vapour converters. GENERAL ELECTRIC CO., Ltd. Feb. 9, 1956 [Feb. 28, 1955], No. 5898/55. Class 39(1). A graphite anode for a mercury arc rectifier is shaped as shown to assist in starting up from cold. The mass of the wall 3 is low compared with that of the central body part 1 so at high current values when the arc tends to rise up the side of the anode this wall warms up very quickly and tendency to backfire is reduced. The whole mass of the anode is lower than that of a conventional anode without an annular channel 4 so that the whole anode warms up more quickly than a conventional anode. The channel 4 also facilitates out-gassing of the anode during manufacture.

Emulsions, making.-Liquids are emulsified or brought to reaction by means of a jet of compressed gases or vapours wholly immersed in a body of one liquid, to which a protective colloid may be added and in which the gas or vapour condenses. one or more other liquids being fed to the jet. In an example, steam is led by a pipe 6 to an injector 5 wholly submerged in a solution of potash soap 12 supplied continuously from a tank 3 and tapped off by an overflow 10. The liquid to be emulsified therein, for example mineral oil, is supplied from a tank 8 to a circular gap 13 in the injector. The jet may be annular as in Fig. 2 and may be heated or cooled by a jacket 21. The interchangeable conical member 20 admits of adjustment of the jet, and by means of the screw-threaded cover 15 the width of the gap 18 to which the other liquid is fed', may be varied. Fig. 3 shows a device for feeding one liquid by means of a pipe 24 and adjustable slotted member 25 to the interior of an annular jet 23 and another liquid from the receptacle 27 to the exterior thereof. The receptacle 27 may be divided by partitions into a number of chambers so that several liquids may be fed simultaneously to the jet, which may also be elliptical. In all cases the injector device is wholly immersed within a body of liquid, in which the atomizing agent condenses. If petroleum be employed as the dispersion medium, then petroleum or benzine vapour is suitable as the atomizing agent.
