IPC: E06B3/80
Filed: 1953-01-29
Abstract: 719,189. Flexible doors. NEWMAN & SONS, Ltd., W., and SHEAD, H. C. Oct. 16, 1953 [Jan. 29, 1953], No. 2538/53. Class 20 (3) The overlapping edges of double swing doors 1, 2, of flexible material, e.g. canvas-reinforced rubber have co-operating magnetic means for preventing separation of the edges as by wind pressure when the doors are closed. A bar-type magnet may be fitted in an aperture in each edge and held in place by thin plates a riveted together on both sides of the door. The poles of the two magnets are reversed so that the edges are held together until the impact as of a truck &c. forces the doors apart. Two or more pairs of magnets at different heights may be provided ; the magnet on one edge may be replaced by an iron or steel plate serving as an armature. The vertical inner edge and the top edge of each door are attached to rigid tubes 3, 4, and the doors are controlled by spring closing mechanism.

Abstract: 396,080. Hydraulic transmission of power. JONES & LAMSON MACHINE CO., Springfield, Vermont, U.S.A.-(Assignees of Flanders, R. E. ; Cherry Hill, Springfield, Vermont, U.S.A.) Jan. 28, 1932, No. 2631. Convention date, Jan. 28, 1931. [Class 69 (ii).] In hydraulic power transmission systems, e.g. of the kind described in Specification 355,702, the metering device for regulating the speed of the driven member is of the swashplate type and its capacity may be varied. As shown, it comprises a cylinder body 22, Fig. 3, rotating on a normally stationary distributing valve 18, and containing spring- pressed pistons 25 engaging a stationary adjustable swash plate 27. The valve is turned through 180‹ to reverse its action when the rotor is reversed, the amount of turning being determined by surfaces 62, 61 and a fixed stop 65 ; the turning is effected by the friction between the rotor and the valve, the valve having a friction member 78 pressed by a spring against a friction member 75 keyed to the rotor. The pivotal axis 90 of the swashplate is disposed eccentric to the rotor axis, so that liquid thrust acts to keep a screw 95 in engagement with the cam 97 which effects adjustment of the plate. The shaft of the cam 97 is held in adjusted position by a friction member 101, Fig. 1, engaging a spring-pressed friction member 102.

Abstract: 124,190. British Westinghouse Electric & Manufacturing Co., (Assignees of Chubb, L. TV.). March 13, 1918, [Convention date]. Rotary transformers.-In a system of conversion from single-phase currents to polyphase currents by means of a phase-converter of the synchronous type and in which balanced electromotive forces are obtained by inter-connexions of the single-phase transformer and the primary of the converter as, for instance, described in Specifications 121,486, 121,487, means are provided for the automatic variation of the excitation of the converter secondary. In the form shown, these means consist of a coil 16 energized by the load current, and a core attached to a spring 17 to control the amount of resistance 8 connected in the circuit of the exciting winding 5. The apparatus is adjusted so that, at full load current, the proper current flows in the winding 5 for unity power factor so that on light loads the converter is over-excited and the power factor consequently improved. When, on no load, the middle points of the transformer sections 13, 14 are joined to keep the converter in operation, the excitation is still further increased.

[Class 110 (i)] The rotor of a liquid ring pump is sealed axially and peripherally by high-pressure liquid. The liquid is introduced at 44 into a chamber 43. A part of it seals the surfaces 38, 39 at the small end of the cone and the shaft and stuffing- box 17, 18, a part passes through ports 45 and mixes with the air being pumped and the rest passes through a control valve 48 to a chamber 46. After leaving the chamber 46 via port 49, some of the liquid passes through a port 52 to seal the surfaces 34, 36 and some passes through ports 50, 54 to seal the peripheral surface 34a. The mixture of air and liquid from the discharge passes to a separator. With large pressures labyrinth form of sealing is used at the periphery of the rotor. In a modification, the sealing liquid is delivered directly into the inlet passage 26 where it combines with the air being compressed and passes to the rotor. The liquid circulates through the passages in the reverse direction to that described and in so doing seals the running clearances. In another modification, the liquid used to seal the small end of the cone is introduced at 44 and the rest of the sealing liquid, taken from the bottom of the separator, is introduced at 61a. In a further modification, all the sealing liquid is introduced at 61a and the liquid used to make up losses in the ring and for cooling is introduced at 57.
