Abstract: A method and an apparatus for separating solid or drop-like particles from an air flow is provided. The air flows through a separator chamber between an electrode, ion generating means or like particle charging device disposed in the separator chamber, and a grounded collector surface, so that the particles are charged by the charging device and accumulate on the collector surface. The air flows along a substantially spiral path around the charging device in at least a part of the separator chamber so that due to the action of centrifugal force at least a portion of the particles pass toward the grounded collector surface at the periphery of the chamber. A small flow of purified air flows downwardly in a central part of the separator chamber so that it washes the charging device in the separator chamber.

Abstract: 524,989. Electric cables and couplings. PIRELLI-GENERAL CABLE WORKS, Ltd., and HORLEY, R. E. Jan. 12, 1939, No. 1035. [Classes 36 and 38 (i)] In an electric cable, the dielectric material is surrounded with,a metal &c. sheath impervious to gas, around which and spaced therefrom is a second similarly impervious sheath, the space within the inner sheath and that between the sheaths being charged with gas under pressure. The two spaces may be charged with different gases and at different pressures. In Fig. 1, the conductor 1 has insulation 2 within a metal sheath 3 with reinforcement 4 about which, spaced by members 5, is a second metal sheath 6 with reinforcement 7 and protective covering 8. The space within the sheath 3, and that between the sheaths 3, 6 are charged with gas. At a joint, Fig. 4, the spaces within the sheath 3 and between the sheaths 3, 6 of one section may be connected to the corresponding spaces of an adjoining section by means of sleeves 10, 12 with plumbed joints, 11, 13 ; tubular connections 14, 15 may be provided for supply of gas and/or communication with pressure-indicating or warning devices. In another form, Fig. 5, each of the joined cables has an inner gas-tight sealing end 16 through which the conductors 1 project for connection by a flexible member 17 ; one sealing end 16 is wiped to the sheath 3 at 11 and the other fits in a diaphragm 18 extending across the sleeve 12 and sweated at 20 to the other sheath 3. An insulating sleeve 21 is located between the sealing ends 16 and the sleeve 12, the gas-filled spaces within one cable being cut off from those of the other. A terminal device, Fig. 6, has the inner sheath 3 fitted within a sleeve 16 through the end of which the end of the conductor projects to form a plug 22 co-operating with a socket formed in a metal cup 23 of an insulator 24 communicating with the gas-filled space between the sheaths 3, 6. The insulation within the inner sheath may be impregnated with an oil &c. which develops gas under the action of the electric field if the internal pressure falls unduly. Reinforcement of the inner sheath may be omitted. A cable may have a higher pressure within the sheath 3 than between the sheaths 3, 6, and an alarm device may be connected to the sheath 6 to give warning of a fall in pressure due to a leak in the sheath 6 or a rise due to a leak in the sheath 3.

[Class 83 (iii).] A screwing or tapping machine has the toolspindle splined within a rotary sleeve adapted to be driven by one of two oppositely rotating pulleys thereon through split-ring clutches which are actuated by plungers controlled through a latch by a trip device on the tool-spindle. The tool-spindle b is splined by a key u to a bush v on which is secured the rotary sleeve a, the pulleys d, d<1> driven in opposite directions being rotatably mounted on the sleeve. Split piston rings s within the pulleys are adapted to be expanded to clutch either wheel to the sleeve by means of tapered plungers r, levers q and levers p pivoted on the sleeve and rocked by a slidable collar e. In operation, the tool-spindle is fed to the work by a hand-lever f acting through an extension b<1> of the spindle against the pressure of a spring b<2>. After a predetermined travel a loose collar g<2>, located between fixed collars g, g<1> on the spindle, engages by means of pins h thereon with a lever j pivoted at k and causes the lever to raise a lever l, pivoted at l<1>, and thereby removes a latch m from the path of a collar n<1>. A spring o, acting through the collar, then rocks a lever n to slide the collar e and reverse the direction of rotation of the tool. A clutch-operating rod w is provided, the backward movement of which can be regulated by a lock-nut x, and a spring brake-sleeve may be mounted on the sleeve a to coact with a tapered end on the collar e and bring the spindle to rest instantaneously.

Abstract: 140,539. Little, I. C., and Crook, E. E. Jan. 17, 1919. Airships carrying auxiliary aircraft; cars and cabins.-Air-ships which carry aeroplanes are provided with means for ready pulling up, attachment, and release of the aeroplanes. Theaeroplane is suspended at a single point and drawn up against a suitable structure which prevents the aeroplane from moving relatively to the air-ship. Struts G, F, Fig. 2, attached to upper and lower members H, F of the keel or corridor of a rigid air-ship, carry a transverse member A, which has an under surface cambered to suit the upper surface of the aeroplane wing. This member A may be pivotally and adjustably attached to the struts, so that the attitude of the aeroplane may be varied relative to the air-ship. The tail may also be prevented from swinging by a fork or yoke L at the foot of a pivoted strut K, which is moved into and out of position by a rod M adapted to be clamped in a bracket N. The suspension gear comprises four cables a, Fig. 4, attached to the aeroplane and a common ring b. To the ring b, a quickrelease device C is connected, which is slung by a turn-buckle B and sling D from the bottom girder joint. Alternatively, the cable carrying the release device may pass inboard to a winch. In the case of non-rigid air-ships without a permanent power plant or car, an horizontal frame is slung from the envelope, instead of a car, and the aeroplane attached to a transverse member A thereon. For rigid air-ships with internalcorridors, the girder framework supporting the member A is of little depth, the aeroplane being drawn up close under the ship.
