Title: Improvements in or relating to electric alarm devices
IPC: G08B19/00
Filed: 1924-08-19
Abstract: 220,945. Geffcken, R. H. H., and Richter, R. H. Aug. 23, 1923, [Convention date]. Thermionic relays and generators; light and heat radiations, control of apparatus by.--Electric discharge tubes are so arranged in connection with burglary, theft, or fire alarms that, when the alarm is to be given an alteration occurs in the direct current flowing through a resistance, thus changing the potential difference between the electrodes and causing a considerable alteration in the discharge current. In the arrangement shown in Fig. 1, the electrodes 2, 4 of a three-electrode valve 1 are connected to a direct or alternating current source, and the three electrodes 2, 3, 4 are suitably connected to an oscillatory circuit 5 for the production of oscillations therein. Between the grid 3 and filament 2 is connected a potassium cell 6 with series and shunt resistances so proportioned that under normal conditions the valve is just not oscillating. The alarm is given when the cell 6 is exposed to light, which causes the negative potential on the grid 3 to be reduced, so permitting the valve to oscillate. The sudden alteration of the supply current operates a signalreleasing device 7; or an incandescent lamp associated with the circuit 5 ma.y be lit. Fig. 2 shows the use of a glow discharge lamp 8 connected to a supply source 9, 10 through a signal-release device 14 and resistance 11, the supply lead 10 being earthed. In shunt to the lamp are a resistance 13 and the extended alarm wire 12. The voltage across the lamp is insufficient to produce a glow discharge, until the wire 12 is cut or earthed. The signal may be given by the device 14, or by the lamp itself. The Specification as open to inspection under Sect. 91 (3) (a) states that if alternating current supply is used, the discharge tube is arranged to have different glow voltages for the two directions of the applied voltage, or to pass different discharge currents in the two directions, so that a rectifying action occurs, and a direct current, relay may be used! for releasing the signal. Combined A.C. and D.C. voltage may be applied to the lamp, so as to maintain a discharge when once set up. This subject-matter does not appear in the Specification as accepted.

To increase the resistance of turbine blades to deflection relative to each other in a direction parallel to the rotor axis, web members extend across the width of each blade and are secured to the blades, intermediate the blade tips and roots, by at least two pins or by at least one projection of non-circular cross-section, whereby the web members are prevented from being angularly displaced about a circumferential axis. In one embodiment of the invention, Figs. 1 and 3, the web member is constituted by metal pressings 8 brazed or otherwise connected together and having channel-shaped outer edges which fit over pins 2a, 3a secured therein. The pins pass through apertures in the blades and are secured in the ends of the adjacent web member. The web members are shaped to fit between the blades and are brazed or otherwise secured thereto. In the embodiment shown in Figs. 7 and 8, the rigid web member 22 has hollow formations 24 secured to the blades by pins, while fairings 25a are secured to the crossmember 23. In a third embodiment, see Fig. 6, each web member 10 is of aerofoil section and is provided with non-circular bosses or dogs 11 which engage with recesses formed in the blades. Pins 14 engage in the bores 12 formed in the bosses and extend into bores 15 in the adjacent web member. Alternatively two or more sets of hollow bosses, located out of line, may be provided. In a modification the bosses are dispensed with and two sets of holes are provided in the web member to accommodate the blade engaging pins.

Leuco compounds of vat-dyes, derivatives of. -Vat-dyes are converted into derivatives by treating them with alkyl esters of monochloracetic acid in the presence of a metal and a tertiary organic base such as pyridine or quinoline or their homologues, with or without a diluent. The initial products of reaction can be converted bv treatment with alkali into watersoluble compounds : Textile materials can be dyed or printed with the latter compounds and the shades of the parent vat-dyestuffs developed on the fibre by hydrolysis and oxidation for example as described in Specifications 245,587 and 247,787. According to examples ethylchloracetate is condensed with dimethoxydibenzanthrone, indanthrone, dibenzanthrone, or indigo, in presence of zinc dust and pyridine or a mixture thereof with chlorbenzene, and with flavanthrone in presence of copper and pyridine. The resulting products, on extraction with warm caustic soda solution yield solutions which dye cotton and wool; the product from indanthrone is not completely soluble in alkali, the residue containing a pyridine-soluble compound which does not yield indanthrone with acid oxidizing agents.

Title: Vacuum tube gating circuits
IPC: H03K17/54
Filed: 1954-07-07
Abstract: 781,585. Gating circuits. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. July 7, 1954 [July 9, 1953], No. 19956/54. Class 40 (6). A gating circuit comprises a triode discharge tube having the signal to be gated applied to its control-grid and the gating signal applied across a cathode resistor the output being derived from the anode load and in which a uni-directionally conducting device is connected to the cathode load resistor so as to apply to the cathode either a D.C. bias which renders the gate open or a gating voltage which closes the gate. Fig. 1 shows a gating circuit in which the signal to be gated is applied to the control grid of tube 1 at terminal 6 and in which diode 9 is normally conducting to apply a voltage +v to the cathode so that tube 1 conducts and an output signal is produced at lead 3. When a gating signal having a voltage exceeding +v is applied at terminal 11 diode 9 and tube 1 are cut-off and the output at 3 ceases. In a modification, Fig. 2 (not shown), the gating signal is applied to the cathode via a further rectifier. In a further modification, Fig. 3 (not shown), two gating signals are applied to the cathode of the triode via individual rectifiers. In a modification shown in Fig. 4 two gating signals are applied at 11<SP>1</SP>, 11<SP>2</SP> via a diode coincidence gate 131, 132 so that the triode gate 1 is closed only when two gating signals are applied at 11<SP>1</SP>, 11<SP>2</SP> simultaneously. Fig. 5 shows a modification in which a single gating signal is applied at 18 via a cathode follower stage 16 to effect the simultaneous gating of tubes 1<SP>1</SP>, 1<SP>2</SP> ... 1<SP>n</SP> which are isolated by rectifiers 12<SP>1</SP>, 12<SP>2</SP> ... 12<SP>n</SP>. In a further modification, Fig. 6 (not shown), the isolating rectifiers of Fig. 5 are dispensed with and the cathode follower and gating stage share a common cathode load resistor.

Abstract: 885,684. Radar. FUNKWERK KOPENICK VEB. June 25, 1958, No. 20360/58. Class 40(7). [Also in Group XL(b)] A phase-shifter is arranged in a waveguide between twoindependently controllable ferrite Faraday rotators. As shown, two ferrite rotators 2, 4 are arranged serially in the waveguide feeder 1 of a radar aerial. Between them is arranged a differential phase-shifter 3 of the kind which produces a 90 degrees phase shift between two orthogonally polarized linear components of a wave. This may consist of a quarter-wave plate. In the most general case the interference received is elliptically polarized and the rotator 2 is adjusted to rotate the axes of the ellipse such that the plate 3 produces a 90 degrees phase-shift between the linear components of the elliptical wave. The resultant linearly polarized wave is rotated by the second rotator 4 to such an extent that it is incompatible with the rectangular-section feeder 5 of the receiver 6. Suitable means are provided for coupling the wave to an absorbing device. If it is desired to observe the interference, the rotation of the rotator 4 is adjusted such that the wave is compatible with the guide 5 and is coupled to the receiver 6. It is stated in the Specification that when the arrangement is used for suppression, the target echo contains components different from those of the interference and that these components are present in sufficient intensity to affect the receiver. The rotators may consist of ferrite rods and the amounts of rotation may be varied by the currents I 1 , I2 in the polarizing solenoids. The solenoids may be wound directly upon the rods or upon a dielectric or metallic coating on the rods. The two rotators may comprise a single ferrite rod having two spaced solenoids wound upon it and the phase-shifter may consist of a dielectric plate inserted in the rod. The rod may be used as a primary radiator in the radar aerial.
