Title: A method of and apparatus for casting a material of which at least part evaporates or dissociates intensively at pouring temperature
IPC: B22D18/00
Filed: 1969-03-27
Abstract: 1,261,753. Casting under gas pressure. INSTITUT PO METALOZNANIE I TECHNOLOGIA NA METALITE. 27 March, 1969 [5 April, 1968], No. 16239/69. Heading B5A. [Also in Division B3] In order to prevent evaporation or dissociation during melting and casting, the melting of material to be cast, or of its constituents if it is, for example, an alloy, and the pouring and solidification, are carried out in an atmosphere of gas at a pressure above the vapour pressure of the material or each of its constituents which would otherwise evaporate or dissociate at the operating temperatures. The gas pressure is maintained over any remaining melt to be cast whilst the cast material is brought to atmospheric pressure to permit its removal. The material to be cast may be chemically active, in which case a neutral or reducing gas is used. In the embodiment shown, the solid material or its constituents are melted in a crucible 1, possibly protected by a flux layer, by a heater 2, in a sealed chamber 3 in which the pressure is raised by gas from a reservoir 6 through valves 7 and 8. During this time, a mould 11 in a chamber 10 is exposed to atmospheric pressure because a valve 12 is open. Then the valve.12 is closed and a valve 9 is opened and the chambers 3 and 10 are exposed to a pressure high enough to keep the melt liquid and stable. A closure device 5 is then opened and the pressure in chamber 3 is increased to raise melt into the mould 11. The gas pressure for the melt may be applied to the crucible alone and not to the heater 2 and chamber 3. In another embodiment, Figs. 2, 3 (not shown), instead of using a pressure differential to get the melt into the mould, the apparatus is tiltable to get the crucible above the mould for pouring. In a further embodiment, melt is raised by gas pressure, as in Fig. 1, but into a cylinder (13) from which a piston (14) forces it into the mould located to one side.  Reference has been directed by the Comptroller to Specification 989,353.

Title: Improvements in circuits for operating gaseous electric discharge tubes
IPC: H05B41/46
Filed: 1946-06-04
Abstract: 612,786. Starting circuits for discharge tubes. PHILIPS LAMPS, Ltd. June 4, 1946, No. 16937. Convention date, March 18, 1942. [Class 38 (iv)] To avoid continued flow of excessive current through the resonant starting circuit of a discharge tube, a time-lag switch, having an operating element carrying the resonant current or connected in parallel with a part of the resonant circuit, is adapted to de-tune the circuit if the tube fails to ignite within the delay period. The switch, which may be either of the thermal or electromagnetic type, may de-tune the circuit either by removing or adding impedance to it. As shown in Fig. 1, the contacts 13, 14 of a thermal switch 12, having its heating coil 11 in series with the resonant circuit 3, 4, are arranged to shortcircuit the choke 4 if the heavy resonant current persists due to failure of the discharge tube 1, the condenser then passing a reduced current which, however, is sufficient to maintain the switch contacts closed. Under normal conditions, the tube de-tunes the circuit sufficiently to prevent operation of the switch. The switch may remove only a portion of the total inductance of the circuit. In another arrangement, the switch heater shunts the choke and its contacts .control the amount of capacity in circuit. Fig. 4 shows a circuit comprising a switch 12 having heaters 11, 19 associated, respectively, with bimetallic elements 13, 18 carrying co-operating contacts 17, 14. A transformer 21, 22 connected in the resonant circuit 3, 4 provides for initial heating of the filamentary electrodes 7, 8 of the tube 1. If the tube fails to strike, element 13 is sufficiently heated for contacts 17, 14 to engage, thereby short-circuiting winding 22 and condenser 3 by heater 19 which then maintains the contacts closed.

Class 39(1) A travelling wave tube in which a wave injected into a delay line is amplified by interaction with an electron beam which is propagated parallel to the line and perpendicularly to crossed electric and magnetic fields, at a velocity equal to the ratio of these two fields and to the phase velocity of the wave, is modified to act as a frequency multiplier by dividing the delay line into two sections. The first section is traversed by a wave of the fundamental frequency to be multiplied, the beam velocity in this section being equal to the phase velocity of the wave. In the second section the beam velocity is made equal to the phase velocity of the desired harmonic wave. The amplified output of desired harmonic frequency is taken from this section. The two sections are separated by an attenuating region, and the beam velocity is changed in the second section by altering the value of the electrostatic field. The delay line is opposite a negative electrode, and either the negative electrode is divided into two parts maintained at different potentials, or the two sections of the delay line may be maintained at different potentials. Alternatively the distance between the delay line sections and the negative electrode is different for the two sections. As shown in Fig. 6, the negative electrode 4 is stepped opposite the attenuating region between delay line sections 1 and 2. In Fig. 7, the delay line sections 1 and 2 are at different distances from the negative electrode 4, the attenuating part 3b of section 2 being superimposed on the attenuating part 3a of section 1. Different methods indicated may be combined with one another. The first section of the delay line may function as a self-oscillator for the fundamental wave.
