Title: Improvements in or relating to operating circuits for noise tubes
Inventor: DENSON COLIN IVOR
IPC: H03B29/00
Filed: 1964-04-23
Abstract: 1,047,065. Noise generators; pulse circuits. NORE ELECTRIC CO. Ltd. April 22, 1965 [April 23, 1964], No. 16795/64. Headings H3B and H3P. Operation of a noise tube, NT (the Figure, not shown), is initiated by applying to its anode high voltage transients which are generated by feeding the output of a multivibrator V1A, V1B, via contacts of a relay RL1 to the grid of a valve V2, the relay contacts being automatically opened to discontinue the generation of transients when the noise tube has begun to operate. The anodes of both the noise tube and the valve V2 are connected through an inductance L to a constant current H.T. source, T3, the inductance serving to produce the high voltage transients as the valve V2 is switched on and off by the square wave applied to its grid. When the noise tube begins to operate, its impedance drops, and its current therefore increases and the current from the source T3 available to hold the relay RL1 falls, thus allowing the contacts to open. Two ganged switches S1 and S2 each have four positions: in the first, P1, the circuit operates as described above; in the second and third positions P2, P3 the multivibrator output is supplied directly to the valve V2 (i.e. the source of transients cannot be automatically disconnected), the multivibrator frequency being determined by R1 and R4, respectively; and in the fourth position, P4, an external source, T4, replaces the multivibrator. A further switch (not shown) may be ganged to S1 and S2 to break the H.T. supply, T2, to the multivibrator when S1 and S2 are in the P1 position and a further set of contacts of relay RL1 used to bridge the contacts of the further switch so that the multivibrator ceases to function when the noise tube is operated.

Title: Improvements in or relating to hydraulic remote control apparatus
IPC: F15B7/08
Filed: 1941-12-31
Abstract: 555,202. Hydraulic control mechanism : fluidpressure brakes. AMERY, G. Dec. 31, 1941, No. 16861. [Class 69 (ii)] [Also in Group XXXIV] A hydraulic control device of the kind in which a transmitting piston or bellows 21,, Fig. 1, is actuated in a cylinder 12 connected by a pipe 11 to a receiving cylinder 40, Fig. 2, fitted with a spring-controlled piston 41 or bellows connected to a crank with an operating arm 46 connected to the actuated member is provided with normally closed valve means 19, 22 so as to lock the liquid against movement except under the influence of the actuator. The piston 21 is depressed by crank mechanism 30, 31, 33, the crank arm 33 passing freely through the crank hub and being controlled by a spring 39 and cam 38 so as to move radially of the hub so as to increase the leverage as the crank 33 is moved counterclockwise, thereby compensating for the increased pressure of a spring 47 upon the piston 41 as this piston is raised. Movement of the piston 41 occurs only when the valve opens at a predetermined pressure. The return movement is controlled by the valve 22 normally closed by a spring 23, the valve 22 being formed at the bottom of a tubular stem 25 integral with an enlarged stem 27 guided by a passage 26 in the piston. On raising of the piston 21 the valve 22 opens under the suction produced by the piston, the pressure in the pipe 11 due to the piston 41, and by the dash-pot effect of liquid trapped between the stem 27 and an abutment disc 29 which limits the downward movement of the valve 22 relatively to the piston. The spring 47 can be connected to the piston 41 by a cam-and-lever device similar to the adjustable crank described in connection with the transmitter. The valve 22 may be replaced by a cylindrical lift valve with a conical face which fits in the bore 26 and is depressed by a spring in the bore 26. The valve is connected to the piston by a clutch device which permits the piston to move downwards relatively to the valve but which raises the valve on upward movement of the piston. The cylinder 21 is fitted with a reservoir 34 which is connected to the cylinder by an aperture 35 in the raised position of the piston.

Title: Fluid control valve mechanism
IPC: B60T11/228
Filed: 1960-05-16
Abstract: 955,470. Valves. GABRIEL CO. May 16, 1960 [May 18, 1959], No. 17266/60. Heading F2V. A valve mechanism has at least one valve assembly, the or each valve assembly comprising a first valve seat engageable by a slidable first member having formed thereon a second valve seat, a slidable second member engageable with the second valve seat, biasing means for biasing the first member to close both valve seats, the second member adapted for movement in two directions from an inoperative position in which both first and second valve seats are closed, movement of the second member in one direction uncovering the second valve seat but leaving the first valve seat closed, and movement in the other direction uncovering the first seat but keeping the second seat closed, and a motive device adapted for movement in two directions, movement in one direction positively moving the second member in one direction from the inoperative position and movement in the other direction allowing fluid pressure to move the second member off the second seat. When the valve 28 at the right of Fig. 1 is depressed by a lever 54 fluid from an inlet port 68 flows by way of annular grooves 62 connected by a passage 66 through a port 64, a counterbore 22 and a bore 42, Fig. 5, into a flexible conduit 96 to displace a motor piston 90 to the right. The pressure of the exhaust fluid lifts the valve 50 at the left of Fig. 1 to open a passage 30 communicating through annular grooves and passages, similar to those for the inlet port, with an exhaust port 78. The seats 25 for the valves 28 are a press fit in inserts 18 which in turn are a press fit in a block 14 while flanges 34 on each valve have a larger area on their upper surfaces than on their lower surfaces exposed to inlet pressure to reduce the loading imposed by coil springs 38. Excessive inlet pressure unseats the valves so that the device cannot be operated. Fig. 6 shows an alternative construction in which the motor ports 184 communicate with bores 114 containing the valve members while inlet and exhaust ports communicate with counterbores 116. The valves are actuated by a cam 173 through a roller 170 and a lever 156. A spring 164 of greater strength than a spring 128 loading the valve at the right of the Figure acts on a bifurcated end of the lever through a washer 166 and a pin 160 to ensure that the roller 170 stays in contact with the cam 173. The valves 144 may be replaced by ballshaped closure members.

Title: Improvements relating to the manufacture of vegetable tanning agents
IPC: C14C3/12
Filed: 1920-06-25
Abstract: 146,165. Renner, H., and Moeller, W. Feb. 10, 1914, [Convention date]. Extracts, making and treating.-Vegetable tanning materials are decolorized and rendered more soluble by treatment with acid resins, which are products of condensation of sulphonated hydrocarbons. To obtain an extract soluble in warm water and separating only to a small extent on cooling 1 to 5 per cent of acid resin suffices, while to obtain an extract soluble in the cold 10 to 15 per cent is necessary. The degree of solubility and the character of the extract obtained are influenced by previous complete or partial neutralization of free sulphonic acids present in the acid resin. The term " acid resin " includes the sediment produced in purifying mineral oils with sulphuric acid, and the products obtained from natural hydrocarbons such as asphalt, mineral wax, ceresine, paraffin, or other products of the distillation of coal tar or wood tar, as described in Specification 146,166. Examples are given of the treatment of quebracho and of mangrove extract, increase of pressure being stated to hasten the action in each case. Specification 7138/13 and the prior use of acid resins as tanning-agents are referred to. Reference has been directed by the Comptroller to Specification 18259/13.
