Title: Improvements relating to the separation of volatile liquids from solid dielectric material
IPC: F26B13/00
Filed: 1957-03-15
Abstract: <PICT:0854439/III/1> <PICT:0854439/III/2> <PICT:0854439/III/3> <PICT:0854439/III/4> Volatile liquid is removed from solid dielectric material by dielectric heating within an enclosure wherein the pressure is at least atmospheric, and condensing means communicating with the atmosphere within the enclosure condense the vapour at a rate such that the evolved vapour flows to the condensing means.  As shown, a rayon yarn cake 10 is dried by being placed on a rotatable insulated support 11 between high frequency electrodes 12, 13 within a chamber 18, and the vapour therefrom flows through an opening 21 into a condensing chamber 22 containing cooling conduits 23, and condensate is drained away through a conduit 24. Steam pipes 20 around the chamber walls prevent condensation thereon.  In Figs. 2 and 3 a series of rayon cakes 10 is carried by a conveyer 25 through a generally circular chamber 27 surrounding a high frequency oscillator and having an inlet 26 and an outlet 28.  Each cake is mounted on a rotatable insulating support 31 and the conveyor is driven by a motor 33.  Electrodes 38, 39 are arranged concentrically with the chamber and the cakes are carried around between them.  An annular condensing chamber 40 with condensate drainage pipes 42 is located about the main chamber, and vapour flows into it through an annular opening 41. Heating coils 43 prevent condensation within the main chamber. The cake supporting means may comprise an intermediate cylindrical electrode 120, Fig. 5, arranged centrally of the cake and supported by an insulated rotary disc 112 driven via gearing 116. Vent holes 122 in the disc provide a more rapid drying of the cake.

In an hydraulic pump or motor pressure liquid flows, past either valve 25 or valve 26 into a passage 27 through a restrictor 28 and into the space 23, to hold the face valve members in contact, and acts on a piston 51 When a pre-determined pressure is exceeded, the piston 51 moves a valve 46 to vent the chamber 23 through passages 47, 48 and owing to the restrictor 28 pressure on the piston 51 is maintained. If the pump is required to deliver no liquid, the plunger 44 is pulled against a spring 42 so that liquid pressure acting on the piston 51 vents the chamber 23. The present invention is also applicable to compressors and gas engines.

Title: Improvements in and relating to systems of electrical distribution

Abstract: 215,729. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). May 11, 1923, [Convention date]. Vacuum or low-pressure apparatus, arrangements of.-Alternating-current machinery is supplied from a direct-current source through a number of electric valves, and means are provided for maintaining the plate voltages of the valves at a low value during the periods of current transmission. In an arrangement for supplying current to the stator windings of a two-phase induction motor 3, Fig. 1, the direct-current lines 1, 2 are connected through inductances 28, 29 and through a series of valves 6 - - 13 to the primary windings 4, 5 of two transformers, the secondary windings 14, 15 of which are connected to the stator windings of the motor. The valves are of the magnetron type and are rendered non-conducting by creating a magnetic field in the space between anode and cathode by means of coils 18 supplied with current from a source 17. The current to the magnetizing coils of each pair of valves is successively interrupted by means of a commutator 21 having an insulating segment 22, the commutator being driven from the motor 3 through a connection 27 which may be variable. Current is thus permitted to flow alternately through the primary windings of the transformers. The arrangement is such that the individual valves only carry current when the counter E.M.F. of the motor is of the same order of magnitude as the potential of one direct-current source. By varying the speed relation between the commutator and motor, any desired relation between the frequency of the current and the speed of the motor may be obtained. The motor may be started by independently rotating the commutator. In a modified arrangement, Fig. 3, for supplying single-phase current to the stator winding 31 of an eight-pole synchronous motor 32, current is caused to flow alternately through primary windings 33 connected through the plate circuits of thermionic valves 34, 35 to a high-voltage direct-current source 1, 2. Alternating current is supplied from the secondary winding 36 to the stator winding 31. The motor drives a commutator 37 bv means of which the energizing windings of relays 44, 45 are alternately connected to low-voltage directcurren.t mains 40, 46. By the operation of the relays, the grids of the valves 34, 35 are alternately given positive and negative, potentials derived from a direct-current source 47 shunted bv a resistance 48. A series resistance is provided to maintain the plate voltage of each valve substantially constant and at a low value during the half cycle when it is carrying current. The synchronous motor 32 may be started by means of an auxiliary direct-current motor 49 driven from the mains 40, 46. Specification 102,484 is referred to.
