Title: Automatic cut-off valve
IPC: G05D23/02
Filed: 1927-01-17
Abstract: 268,293. Ruud, E. March 25, 1926, [Convention date]. Thermally - actuated valves. - A thermal safety cut-off valve for gas burners having associated pilot burners is provided with automatic mechanical means for holding the valve open until the thermal means becomes operative when lighting the burner, the said thermal means being under the control of the pilot burner and becoming operative only when the pilot flame is extinguished. The gas supply valve 5 is pulled open by a spindle 8 with operating head 10, and a spring 27 forces the lever 25 downwards with the end 26 engaging the end of the valve spindle 8, thus keeping the valve open. When the burner 13<1> has been lit the heat of the pilot burner causes the thermal element to move the rod 22 to the right, thus allowing the stronger spring 17 to force upwards the level 15 and the lever 25, whereupon the rod 8 slides from the upper lever 25 and is engaged by the face 15<1> of the lower lever 15 to maintain the valve 5 open. When the pilot flame is extinguished the thermal element pushes the rod 22 to the left, thus moving the lever 15 downwards to disengage the valve spindle 8 and allowing the valve to close by the action of the spring 6.

Title: Improvements in velocity modulated electron discharge tubes
IPC: F16L3/02
Filed: 1942-02-06
Abstract: 558,143. Velocity-modulated tubes. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Feb. 6, 1942, No. 1618. [Class 39 (i)] In a velocity modulated electron discharge tube wherein the beam passes through a control electrode 7, Fig. 1, situated between two bounding electrodes 6, 8, and is reversed by a brake field electrode 10 to obtain density variation, a further reversal is obtained by the electrode 5 between the gun 3, 4 and the first bounding electrode 6 ; an oscillatory circuit 9 is connected as shown. The potentials and lengths and dispositions are chosen to give appropriate times of flight of electrons, these times being related to the frequency of circuit 9. An electro- or permanentmagnet may be used to focus the beam and thereby ensure several reversals of the electrons. In a modification, two control electrodes 7a, 7b, Fig. 2, are used and the bounding electrodes 6, 8 are connected together. The orifices in these latter are smaller than the cylinder diameters to catch slowed up electrons. The brake field electrode 10 is placed in a cylinder 14 at slightly higher potential so that electron movement is slower at reversal. A modulating potential to control beam intensity may be applied to a control grid at the cathode ; these modulations may be derived from the circuit 9, Fig. 1, or 12, Fig. 2. The electrodes 7a, 7b, Fig. 2, may be connected by a concentric conductor. The subject-matter relating to Figs. 1 and 2 is identical with that of Specifications 640,697 and 640,747, [both in Group XL (a)]. In a further modification, the bounding electrodes are formed by the tubes 23, 24, Fig. 3, the latter being long to provide a closed drift space; a concentrating electrode 35 is interposed between the tube 24 and the brake field electrode 25. The electrons in the reversed beam are collected by the acclerating electrode 16 or a ring 30 of ferromagnetic material may be used to deflect and collect the returning electron beam ; the ring 30 may be outside the tube and a special collector used. Concentrating coils 40 are used and the control electrodes 26, 27 are connected by a Lecher system 28. The reversed beam may be deflected magnetically to be collected by an electrode 20, Fig. 4, after having passed through an output system consisting of bounding electrodes 33, 34 and electrodes 36, 37 connected to a Lecher system 38, which may oscillate at the same frequency as or at a harmonic of the modulating frequency in the system 28. The density modulation is arranged to be completed only on arrival at the electrodes 36, 37. Reference has been directed by the Comptroller to Specification 553,866.

Title: Biocidal composition
Filed: 1949-01-26
Abstract: A mixture of primary thiocyanates prepared from a mixture of alcohols having 6 or more carbon atoms obtained by the oxo-synthesis, i.e. from alkenes, carbon monoxide, and hydrogen, followed by hydrogenation of the aldehydes obtained, is used as an insecticide, acaricide, ovicide, and fungicide.  It may be dissolved in an organic solvent, dispersed in an aqueous medium, mixed with inert fillers or with substances yielding dispersions on addition of water.

Abstract: 1,176,623. Valves. J. V. TRIPOLI. 16 Jan., 1968 [11 July, 1967], No. 2264/68. Heading F2V. In a valve, sealing of the valve member shaft 10, which may be rotatable or reciprocable, with respect to a surrounding member 11, which may be formed integrally with, or form part of a valve housing, is effected by means of a cup-shaped annular member 14 which is formed of tough, flexible and wearresistant material, a resilient, e.g. rubber, insert 18, and a gland 19 which, by means of a cap 20 screwed on to member 11, may be moved downwardly in order to compress the insert and hence radially and axially displace the walls of member 14 into sealing engagement with the shaft and with the walls of member 11. When applied to a rotary conical or a single beat-lift valve (Figs. 2 and 3, not shown), the member 11 is screw-threadably secured on the valve housing, thereby forming part of it, or is similarly secured within the valve housing, respectively. In an alternative form of valve (Fig. 4, not shown), the rubber insert 18 is held between the gland and a rigid member secured to the end of the shaft, the gland, insert and rigid member being surrounded by a flexible member, a part of which is adapted to enter the valve flow passage.

Filed: 1933-01-25
Abstract: 413,383. Valve circuits for wireless reception ; impedance networks. RYALL, L. E., 52, Crescent Gardens, Eastcote, Middlesex. Jan. 25, 1933, No. 2390. [Classes 40 (iii) and 40 (v).] The attenuation of a network comprising one or more metal plate rectifiers arranged as series and /or shunt elements is varied by a D.C. control voltage derived from the main anode current of a valve which varies in accordance with the amplitude of signals applied to its grid. The network may comprise a series rectifier 7, Fig. 1, and shunt resistances 5, 6, the control voltage V being applied to the terminals 8, 9 or a shunt rectifier 14, Fig. 2, and parallel resistance 17 the control voltage V being applied to the terminals 15, 16. In a double arrangement, Fig. 3, series and shunt rectifiers 25, 26 respectively are used, a steady auxiliary voltage v from a source 24 being applied through a resistance 27 to the rectifiers, and the control voltage V to the points 22, 23. Two or more networks may be connected in cascade, as shown in Fig. 6, where two networks 54-61 are interposed between the aerial 53 and the radio frequency amplifier 62 of a radio receiver. The steady auxiliary voltage for the attenuation networks is derived from a resistance 65 forming part of a voltage divider 64-66 connected across the anode supply source, and is applied across condensers 74, 75 in the networks. The control voltage depends on the mean anode current in the detector valve 52 and is applied to the condensers 69, 70 in the networks from the anode of valve 52 through the filter 72, 73. The initial value of the control voltage is regulated by varying the resistance 64, and the attenuation is varied according to the amplitude of the signal to give a constant output from the receiver. The invention is also stated to be adapted for rendering an amplifier inoperative until a signal of above a certain amplitude is received.
