Title: Improvements in fluid-blast circuit breakers
IPC: H01H33/96
Filed: 1935-12-17
Abstract: 452,751. Fluid - blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. Dec. 17, 1935, No. 34989. Convention date, Dec. 17, 1934. [Class 38 (v)] The differential piston mechanism for accomplishing the extinction of the arc in a circuit-breaker bv means of a current of oil or other extinguishing fluid, comprises at least two differential pistons which successively enter into action. One piston 7 comprises the insulating cylinder 8, 10 and the metal collar 9 cooperating with the metal cylinder 4 and the metal collar 22 thereon. The other piston 12 comprises the insulating cylinder 11, 14 and the metal collar 13 co-operating with the cylinder 4 and the insulating cylinder 5. When the movable contact 2 is separated from the fixed contact 1, the arc formed sets up a pressure acting on the collar 9 and also, owing to play between cylinders 8, 11, on the collar 13, tending to depress both collars. When contact 2 uncovers the hole 18, oil streams through the latter and piston 7 moves downwards driving oil through apertures 23 in the cylinder 4. With large currents, the pressure produced causes a sufficient speed of piston 7 to extinguish the arc when 2 passes through 18. With smallcurrent arcs, however, extinction takes place at aperture 19 in piston 12, when the contact 2 uncovers that aperture and permits piston 12 to move downwards. This movement is assisted by the engagement of the part 16 of piston 7 with the part 17 of piston 12, so that both pistons produce the blast. One piston may be arranged entirely within the other or each may move in a separate cylinder. The invention is also applicable to the constructions shown in Specifications 408,077, 409,099, and 423,424.

Title: Method for centrifugally forming fibres
IPC: D04H3/03
Filed: 1959-10-15
Abstract: 938,481. Forming glass fibres. OWENS-CORNING FIBREGLAS CORPORATION. Oct. 15, 1959 [Oct. 27, 1958], No. 35017/59. Class 56. When forming fibres of heat-softenable vitreous material by rotating a body of the material in heat softened condition and projecting streams of the material radially outwards by centrifugal force into an attenuating blast spaced peripherally of the annular body, air which flows into the region peripherally of the annular body under the inductive influence of the attenuating blast is restricted in amount and heated above the ambient temperature. In the form shown in Fig. 4 a rotating distributer 118 and centrifuge 75 are suspended from a tubular shaft 59 running between water-cooled annular jackets 72, 126. A stream of molten glass 53 falls into the distributer and is projected through apertures 122 therein and then through apertures 125 in the centrifuge. The projected streams meet a downward blast of hot gas, e.g. steam, emerging from a slot 80 fed from a manifold 79 to draw the streams into fibres 81 inside a protecting shield 82. A burner 67 comprises a stepped annulus 129 provided with concentric rows of holes fed with a gas-air mixture from the manifold 66. The flame produced is confined by rings 138, 139 and heats the outer part of the centrifuge and the streams emerging from it. Flame from another burner 69, fed from a manifold 68, together with air induced through a restricted aperture defined by a ring 144, are directed on to the outer parts of the emergent streams. Fig. 2 shows the whole unit, a number of which may be mounted side by side and fed from a common forehearth. The unit is movable on rails into position under the foreheath 51 and comprises the motor 58 for driving the tubular shaft 59, Fig. 4, and the unit 65 which contains the gas manifolds 66, 68. The streams of fibres 81 pass through a ring 85 supporting guns 86 which spray the fibres with a binder. The fibres then pass through a hood 91 and are lapped back and forth by alternately energized airjets 93 as they fall on to a conveyer. The downward streams of gas accompanying the fibres pass through the conveyer and are exhausted by a pump from the enclosure 94. Specification 938,482 is referred to.

Title: Refrigerating machines in which the pumping of liquid is effected by intermittently increasing the vapour pressure
IPC: F25B23/00
Filed: 1927-12-29
Abstract: 282,808. Szilard, L., and Einstein, A. Dec. 29, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Refrigerating, absorption and special systems for. - The liquid from the absorber of an absorption system or the condenser of a system of the injection type is forced into the generator from an intermediate chamber by intermittently increasing the vapour pressure of the liquid in the chamber. Liquid from the absorber flows by gravity into the chamber 1, which, during this stage, is cooled, and is subsequently heated and the vapour pressure generated closes the valve 4 and forces the liquid past the valve 5 into the generator. When the pressure in the chamber falls, the valve 5 is closed by vapour pressure in the generator and more liquid flows into the chamber from the absorber and the operation is repeated. In a modification, the valves 4, 5 are replaced by porous earthenware partitions through which the liquid cannot be displaced by the direct vapour pressure in the generator. In another arrangement, the liquid passes by gravity from the absorber through the porous partition 12, Fig. 3, into the cooled intermediate chamber 13 until it reaches the level A-B when a part of it is syphoned into the heated tube 16, from which the vapour returns to the chamber and forces the liquid through the partition 14 into the generator. In a further modification, the liquid passing through the upper partition is directed by a funnel into a tiltable bucket having two compartments which alternately receive and direct a part of the liquid into a tube communicating with an external heated tube, the vapour from which returns into the chamber as before.
