Title: Improvements in or relating to x-ray installations for making radioscopies and radiographs
IPC: H05G1/58
Filed: 1932-02-12
Abstract: 396,803. R÷ntgen-ray apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Feb. 12, 1932, No. 4264. Convention date, Feb. 14, 1931. [Class 39 (i).] An installation comprises a fixed exposure tube 1, Fig. 1, for taking photographs and another fluoroscopic tube 3 for preliminary examination situated nearer to the stand 6 for the subject and the screen and plate-holder position 7. The tube 3 is horizontally and vertically adjustable from a handle 5. The stand 6 may be adjusted hydraulically. The tube 3 is also movable to an off position and the circuit arrangement includes at least one switch in the main circuit or in an auxiliary circuit for the tube 1 which is set, or can only be set, for operation of this tube when the tube 3 is moved, off position. The exposure tube 1 has a rotating anode, and is adapted to be excited from a charged condenser through a choke. In the circuit arrangement shown when the main switch 25, Fig. 2, is closed the relay 31 puts into circuit the transformers 11, 13, 14 and also the relay switch 17 which is thereby opened. The secondary circuit of the transformer 11 includes a rectifier 12, the fluoroscopic tube 3, a byepass resistance 20, a closed relay 21, a meter 32, and a resistance 24 which is in parallel with a neon tube 28 and a condenser 29. After an examination the tube 3 is moved to an off position thereby throwing over the switch 26 to the left. This closes the circuit through a relay 27, coils 22, 19, and the relay 21. Thereby the cathode of the tube 1 is heated and its anode rotating coil is energized. Also the resistance 20 is cut out bv the relav 21 so that the condenser is now charged up by the transformer 11, the primary circuit of which is maintained by the switch 30. The sufficiency of charge is indicated by the tube 28. To effect an exposure the switch 30 may be opened, thereby opening the relay 31 and closing the relay switch 17 so that the condenser discharges through this switch 17 the choke 18 and the tube 1. The relay switch 27 is also opened but with a time lag after the discharge.

Title: Improvements in the insulation of electric wires and cables
IPC: H01B7/02
Filed: 1929-02-09
Abstract: 330,552. British Insulated Cables, Ltd., and Brislee, F. J. Feb. 9, 1929. Insulating-materials for cables or conductors. - Insulation for electric wires or cables consisting of layers of esterified, e.g. acetylated or nitrated cellulose, applied under approximately atmospheric pressure with textile supporting layers is subjected to heat to cause the esterified cellulose to soften so that the textile material is impregnated and adjacent layers of the cellulose unite, giving a solid, non-laminated, insulation. The conductor may be coated directly with layers of cellulose composition or it may he coated with rubber or other vulcanisable material and cellulose layers then applied, the vulcanisation of the rubber and the consolidation of the cellulose insulation being effected simultaneously by heating. The cellulose composition may be applied in the form of tape consisting of the composition combined with a textile support, e.g. calico strips, cotton tape, or braid; or the conductor, covered with cotton braid, may be drawn through a vessel containing a solution of the esterified cellulose composition and then dried and re-coated until the desired thickness is obtained, when a second braid may be applied and the coating repeated. Suitable solutions of the cellulose ester are :-cellulose acetate 10 gms., acetone 85 c.c, alcohol 8 c.c., benzol 7 c.c., triacetin 9 gms. and spirit ingrosine 0.5 gms., or nitrocellulose syrup 26 gms. butyl acetate 18.5 c.c., alcohol 22.5 c.c., benzol 22..5 c.c., and castor oil 7.7 c.c. The acetone, alcohol and benzol act as solvents, the triacetin, butyl acetate and castor oil as plastifiers, and the spirit ingrosine as colouring agent. The heating to consolidate the insulation, which requires a temperature of 100‹ C. or somewhat greater, may be effected as the tape is wound by passing it over an electrically heated surface, or a heated surface may be pressed against the cable after the tape is in place. Alternatively. the cable, after coating, may be drawn through or placed in a heating chamber. To prevent the deformation of the insulation it may be enclosed by a lead sheath or by one or more wrappings of strong tape before heating and where a lead sheath is employed the heat contained in the sheath may be utilised to. consolidate the coating, further heat being supplied if necessary. The protective sheath or tape may afterwards be removed-. Specification 325,210 is referred to.

A base unit for a storage heater comprises a cover 1, a fan 10 for supplying cold air through an aperture 2 in the cover to a conduit in the storage core (not shown) and a second fan 15 which is capable of receiving both cold air and heated air from said conduit. A deflector 12 guides part of the air from fan 10 through aperture 2 while the remainder is supplied through a passage 20 to fan 15. Heated air passes through an aperture 3 in the cover and through an apertured plate 14 to fan 15. The latter may be operated alone, drawing cold air through fan 10, and when fan 10 is additionally energized the turbulence it produces results in less flow through the relatively narrow passage 20 and increased flow through the storage core. In a modification (Fig. 2, not shown) fan 15 has an independent cold air inlet and all of the air from fan 10 passes through the storage core. Fan 15 may be operated continuously while fan 10 is operated intermittently and at varying speeds under the control of a thermostat responsive to the air temperature at the outlet of fan 15. The speed of fan 10 is limited, either as a function of the speed of fan 15 or by a temperature senser in the cold air inlet of fan 15, to prevent it from delivering a greater quantity of air than the latter.

Abstract: 103,572. Forward, C. B. April 7, 1916. Mineral oils, cracking; spray evaporators.- Crude petroleum and petroleum residues are treated to obtain light volatile oils by highly heating the crude oil and atomizing it with superheated steam into a chamber in which a minimum pressure of 75 lb. and a temperature of about 400‹ F. are maintained. The unvolatilized residue is atomized into a second chamber, and the residue from this chamber into a third, and so on. Oil from a tank 11 is forced by a pump 12 through a heater 14 to the atomizer 6 of a chamber 7, and is atomized by superheated steam from a boiler 2 and superheater 4. The unvolatilized residue is atomized successively into chambers 8, 9, 10. The vapours pass through clarifiers 17 and regulating- valves 18 to a condenser 20.
