Title: Sealing valve for mercury-vapour rectifiers
IPC: H01J13/28
Filed: 1937-06-07
Abstract: 496,814. Liquid-seal valves. ENGLISH ELECTRIC CO., Ltd., and EVANS, W. R. June 7, 1937, No. 15715. [Class 135] In a sealing-valve, for use between the preliminary and finishing pumps of an electric arc or discharge apparatus, having an electromagnetically controlled member adapted to dip into and displace liquid, the vessel containing the liquid and the displacing member is formed of glass or like transparent material, either wholly or at least in a part extending above and below either the normal liquid level or a distinctive part of the displacing member. A cylindrical glass tube 1 has its upper end pressed by a screw 15 against a joint ring 2 on the underside of a magnetic yoke 3 which has a hollow polepiece 6 projecting into the tube. The connection 8 to the finishing pump passes through the polepiece and terminates just above the surface of the mercury contained in the tube 1. The clearance space between the connection 8 and the polepiece 6 communicates with the preliminary pump through a connection 17, a stand pipe 11 being provided to act as an oil trap. A displacing member 5 is held in contact with the surface of the mercury, when the pumps are running, by an energized coil 7, the magnetic circuit being completed by distance pieces 12 and a lower yoke 13. On stoppage of the preliminary pump, the coil is de-energized in known manner and the member 5 falls into the mercury, causing it to rise and seal the end of the connection 8. The member 5 is guided in the tube 1 by pegs 19 and is prevented from sticking to the polepiece 6 by non-magnetic pegs 18.

Filed: 1967-04-06
Abstract: 1,131,553. Colour television; semi-conductor gating circuits. MOTOROLA Inc. 6 April, 1967 [19 May, 1966], No. 15855/67. Headings H3T and H4F. A normally balanced bridge circuit formed of a centre-tapped transformer winding 66 together with a capacitor 43 and the junction capacitance of reversed biased diode 44 prevents the translation of signals from the colour channel to the reference signal channel 21, 32 until the synchronizing "burst" signal interval when a pulse 29 from the scanning &c circuits renders the diode conductive. A second bridge formed of the same transformer winding 66 together with a capacitor 41 and forward biased diode 40 is normally unbalanced to translate the signals from channel 54 to amplifier 24 but becomes balanced in response to pulse 29 so as to prevent passage of the synchronizing "burst". In a first modification, Fig. 3 (not shown), a "colour killer" voltage derived from the reference signal oscillator circuit is applied to the junction point of capacitor 41 and diode 40 to reverse bias the diode and balance the bridge. In a second modification, Fig. 4 (not shown), a variable voltage is applied to the junction point of capacitor 41 and diode 40 so as to vary the diode bias, and hence the bridge transmission, in order to obtain automatic-gain control. Another embodiment of the invention, Fig. 1 (not shown), involves only a single bridge circuit for passing the synchronizing "burst" signal to the reference signal channel.

Title: Improvements in molds for molding articles of pulp
Inventor: WELLS ROGER
IPC: D21J7/00
Filed: 1961-05-02
Abstract: 975,270. Moulding pulp. DIAMOND NATIONAL CORPORATION. May 2, 1961, No. 15927/61. Heading B5A. In a process for making a mould for suction moulding pulp articles, such as that illustrated in Figs. 1 and 2 mould form 50 is partly filled with a mixture fibreglass strands and epoxy resin. In Fig. 5 a number of layers of fibreglass cloth 53 and epoxy resin 54 are shown, but these may be omitted. Tubes 13 are placed across mould and the mould filled leaving ends 14, 17 clear. The resin is then cured, ends 14 trimmed off and sealed with member 15 which may be, for example, a strip of epoxy resin impregnated fibreglass. Ends 17 are sealed into holes in manifold 18 and additional fibreglass-resin mixture used to enclose ends 14 and manifold 18. When the mould has been finally cured, drainage holes 19 are drilled from numerous points on the moulding face of the mould into the tubes. When used for moulding pulp a source of suction is connected to manifold 18 or, alternatively, to remove the moulded pump article a source of pressure air. The device is said to eliminate wetting the moulded article as it is blown off the mould. In another embodiment the ends 14 closed in the above mould may be connected to a second manifold through which pressure air is supplied to remove the moulded article from the mould, suction only being applied to the first manifold thus completely eliminating wetting of the moulded article on removal from the mould by blow-back of water in the suction system. Fig. 9 illusstrates an alternative method of making a suction mould wherein a framework 90 of low melting point material is placed in a mould box 91 over a layer of fibreglass cloth 92 and suspended by the members 93. Casting material is then poured in and allowed to cure. The cured mould is then heated to melt the framework which is poured out to leave passages 97 and manifolds 98 (Fig. 12). Thereafter drainage holes 99 are drilled.

Title: Improvements in detecting and measuring devices for millimetre waves
IPC: H03D9/02
Filed: 1954-05-28
Abstract: 775,185. Power measurements; voltage and current measurement. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 28, 1954 [May 30, 1953], No. 15935/54. Class 37. [Also in Group XL (b)] Device matching a load to a millimetric waveguide comprises a hollow waveguide, a hollow conducting cylinder axially perpendicular to the guide and opening thereinto, a load supported between two conductive members sliding within the cylinder with an input pick-up member of the load extending into the guide, and a shortcircuiting piston displaceable axially within the guide and disposed laterally with respect to the cylinder. Fig. 3 shows on energy transmitting millimetric waveguide 1 comprising a groove in a metallic body 101 closed by another metallic body 102. A cylindrical cavity 6 of the first body normal to the longer wall of the guide contains a threaded spring-loaded adjustable metal plug 201 carrying a silicon crystal 21 contacted by a probe wire 3 having a pick-up loop 4 held axially of the cylindrical cavity 6 by a tantalum holder 5 carried by a threaded spring-loaded adjustable metal plug 53 slidable in a cylindrical and insulatedly lined cavity 501 coaxial with cavity 6, the holder 5 sliding through a copper plate 52 closing the waveguide and being surface oxidized to insulate it therefrom. A terminal 506 for the rectified unidirectional output dependent on the power and wave amplitude of the guide is connected to plug 53 over helical spring 505 and the free end of the guide is terminated by a short-circuiting sliding piston (not shown). The latter is adjustable together with plugs 53, 201 and the position of the loop 4 to present a matching impedance to the guide, so that all the energy therein is absorbed in the load and rectifier circuit. In a modification (Fig. 4) the waveguide having a pick-up loop 4 and associated crystal is terminated in a further guide 8 whose cut-off frequency is higher than the working frequency, through an adjustable phase shifter 16; the guide 8 being in turn terminated in a load impedance 7. A reactive impedance is thus presented to guide 1 at its working frequency, and the phase shifter is effective to vary the effective length of guide 1 between the measuring loop 4 and the input to guide 8, equivalent to adjusting the position of the short-circuiting piston referred to above. The rectifying characteristic of the crystal generates a range of harmonics of the working frequency to one of which the guide 8 is made responsive, and load 7 is adjusted to match the generator impedance of the crystal at the harmonic frequency. The crystal may be replaced by a bolometer resistance for measurement of the energy in the waveguide (Fig. 6, not shown).

Abstract: 677,374. Gasefying solid carbonaceous materials. HUBMANN, O. June 26, 1950 [Oct. 28, 1949], No. 15939/50. Class 55 (i). Solid carbonaceous materials having a high ash content such as oil-shales are gasefied by an alternate blow and run process in at least two inclined chambers 2, preferably connected to a common hopper 1, exothermically and endothermically reacting gasefying agents being supplied through valves 8 and lines 7 to pass downwardly through the fuel beds to chambers 4 and thence to collecting mains 15 and 16. The cycles are so arranged that the blow in one chamber coincides with the run in the opposite chamber, change-over valves 11 being operated so that the gases from the blow period pass out through the main 16 and the gases from the run period through the main 15. A proportion of the blow gases may be led off to a combustion chamber 17 and the hot gaseous products then passed to the hopper 1 to dry the material being charged and to the upper parts of the inclined chambers 2 to preheat the charge. The endothermically-reacting gasefying agents may be steam or gases containing CO 2  such as the gas from another of the chambers. The chambers 2 are provided with moving grates 3 operated by the mechanism 21, ash being withdrawn by moving the pivoted flap 23. The ash serves as a heat accumulator for the process and if insufficient ash is present in the fuel, discarded ash may be recirculated and the temperature of the ash may be increased by adding combustible gases with the exothermically reacting gasefying agents. Liquid or gaseous hydrocarbons may be added to the endothermically reacting gasefying agents to increase the calorific value of the gases produced.
