IPC: F23D11/24
Filed: 1950-07-28
Abstract: 681,322. Liquid fuel burners. HOBSON Ltd., H. M. June 27, 1951 [July 28, 1950], No. 18901/50. Class 75(i) A liquid fuel burner nozzle comprises a main swirl chamber 28, Fig. 1, and a pilot swirl chamber 24 each adjacent and open to the nozzle outlet, and a normally closed valve, e.g. a ball valve 17 controlling the flow of fuel from the nozzle inlet 13 to the main swirl chamber 28, the valve 17 being arranged to open when the fuel pressure reaches a predetermined value. When the fuel pressure is low the fuel is supplied only to the pilot swirl chamber 24 through a filter 29, a pair of bores 30 in a sleeve 14 and swirl passages 31 in the rear face of a plate 22. When the fuel pressure rises to a certain value the ball valve 17 is lifted off its seat, against the action of a spring 18, to admit fuel to a chamber 32 in the sleeve 14 from which the fuel flows through a pair of passages 33, Fig. 5, and swirl ports 34 in the plate 22 to the main swirl chamber 28. When the fuel pressure rises to a certain higher value a further ball valve 20 is lifted off its seat, admitting fuel to a chamber 35 from which the fuel flows through four longitudinal passages 36 (not shown), in the sleeve 14 and co-operating swirl ports in the plate 22, to the main swirl chamber 28 thereby increasing the discharge from the latter.

Title: Process for the production of magnetogram carrier tapes
IPC: G11B5/842
Filed: 1954-06-29
Abstract: 781,447. Magnetic dust structures. BADISCHE ANILIN- & SODA-FABRIK AKT.-GES. June 29, 1954 [June 30, 1953], No. 18982/54. Class 38 (2). Magnetic recording tape is made by applying to a carrier foil a layer of powdered magnetic material in an organic binder which contains substantially no softening agent or inactive pigment, the finished foil being heated, if desired, with accompanying change in length, e.g. by stretching, before or after being cut into tape, whereby the tendency of the tape to curl so as to become concave towards the side of the active layer is reduced. The most favourable temperature is the lowest point of the temperature range in which the foil has the maximum elastic extension or the temperature at which elasticity is largely lost. If the foil shrinks when heated, no stress may be needed. Suitable carrier materials are polymers and copolymers of vinyl compounds, the addition of the acrylic acid ester of an alcohol of low molecular weight being mentioned. The active layer may comprise magnetic iron oxide in chlorinated polyvinyl chloride, or vinyl chloride with the butyl ester of acrylic acid in suitable solvents, poured on the carrier. The dried foils may be moved across a domed grooved heated plate, past a heated surface or through a current of hot air (temperatures ranging between 55‹ and 130‹ C. are mentioned) by two sets of rollers moving at different speeds to stretch the foils or cause them to contract. Specification 781,448 is referred to.
