In the construction shown in Fig. 2, the receiver proper, which may comprise a loud-speaker, is housed in the casing A adapted to slide into a home cabinet, the upper portion B<3>, of which may contain a gramophone, while recesses B<4>, B<5> receive aerial inductance and an output filter, the batteries or mains unit being housed in the lower part of the cabinet. The carrying case may be fitted with a frame aerial. The receiver is connected to its supply batteries and aerial by contact strips on its sides engaging contact plungers on the cabinet or carrying case, two contact trips on the top providing connection to a gramophone pick-up. In an alternative form, Figs. 5 and 8, the receiver in a portable case A slides inside the home cabinet the batteries or supply unit being housed in the space behind the receiver. The portable unit, is fitted with batteries from which connections are taken to leaf contacts G'. Similar contacts F<1> for the receiver are connected to contacts G<1> by metal strips H carried on a hinged flap R<1>, which is raised when the receiver is in the home cabinet, thus permitting connection of the receiver to plunger contacts W<1> in a contact bar W which is mounted in the cabinet. Manually-operated plug and socket connections may be fitted between the home cabinet supply source or portable batteries and the receiver. The frame aerial L may be connected to an external aerial to minimize its directional effect when used in the home cabinet, or alternatively it may act as a secondary to a tuned or aperiodic primary inductance LP on a fixed frame LP<1> in the cabinet. Fig. 4 is a connection diagram for the receiver, the circuit connections marked 10, 12, 14, 16, 18 and 20 being established when the receiver is inserted in the home base, while the connections shown in Fig. 4 and made in the portable case.

Title: Improvements in or relating to the production of finely divided oxides of titanium, silicon, zirconium and aluminium
IPC: C01F7/302
Filed: 1949-02-10
Abstract: Finely divided oxides of titanium, silicon, zirconium and aluminium are produced by discharging a mixture of the volatile chloride and oxygen-containing gas (reaction gas) at a temperature not exceeding 500 DEG C. into a reaction chamber and igniting the mixture to form a flame with the aid of an auxiliary chemical reaction delivering at least the amount of heat necessary for the ignition of the reaction mixture.  The gas mixture composition, its temperature and exit velocity are preferably so chosen that the flame is kept at leat 1 mm. and up to 1 m, from the outlet opening for the gases.  The oxygen-containing gas may be mixed with the chloride by feeding it to the still or sublimation chamber for the chloride, or by using it to atomize the superheated chloride.  The auxiliary chemical reaction suitably consists in the combustion of hydrogen, carbon monoxide, oil vapours, &c. and the oxygen required, or a part thereof may be fed in admixture with the reaction gas.  Concentric feed of the gases may be employed when carbon monoxide is used, this may surround the reaction gas, the separately fed oxygen-containing gas constituting the outer layer.  The latter gas should however constitute the intermediate layer when hydrogen is employed.  The direction of at least one of the outer gas streams suitably intersects that of the reaction gas stream, the combustible gas and oxygen-containing gas fed separately may be given a spin around the reaction gas, which also may spin in the same or opposite direction.  A supply of heat additional to that provided by the exothermic chemical reaction may be furnished; thus, the walls of the reaction chamber may be heated.  A variety of burner nozzles is shown consisting of three concentric tubes in which, (a) one or more is formed with helical partition walls to promote spinning of the gases, (b) the outer, or the outer and intermediate, tube terminate in a ring of small nozzles directed skew to the axis of the central tube, and (c) the outer, or the outer and intermediate ducts converge.  The Specification as open to inspection under Sect. 91 is not restricted to the treatment of the four chlorides referred to above.  It also comprises ignition of the reaction gas by other means.  Thus, the use of a resistance heater protected by a ceramic tube, and of an electrode heater is illustrated.  This subject-matter does not appear in the Specification as accepted.

[Class 38 (iv)] [Also in Groups XXXVII and XL (a)] In a glow discharge tube, two bimetallic electrodes 16, 17, move in the same sense to make contact with each other and on cooling remain in contact for part of the way back. The bimetal 17 is shorter and thinner than the bimetal 16, e.g. half as long and 15 per cent thinner, and contacts 8, 9, of tungsten wire, are welded to the upper ends of the bimetals. The free ends of both bimetals move to the right on heating. The filling is a rare gas, e.g. neon, at 40 mms. pressure. The device is used for preheating the electrodes 2, 3, of a gaseous or vapour discharge tube, e.g. a luminescent lowpressure mercury vapour discharge lamp. 5 is a choke and 11 is a condenser. As the contacts 8, 9, remain in contact for a relatively long time, the electrodes 2, 3, have been fully preheated by the time contacts 8, 9, separate.
