Filed: 1924-06-30
Abstract: 228,064. Huebner, H. March 7, 1924, [Convention date]. Fluid-actuated valves.- In air-pressure sprinkler apparatus the discharge of the air pressure is expedited by the provision of an auxiliary apparatus comprising a valve i opened by a diaphragm g moved by the pressure in an air chamber e and closed when water passes, the water exerting pressure on the diaphragm owing to a damming effect brought about by the dimensioning of the valve chambers, such as by making the outlet passage b<2> smaller than the inlet passage b<1>. A gravity valve o may be arranged in a conduit n connecting the air chamber e with the discharge passage b' to allow excessive pressure in the chamber e to pass so that it does not prevent the discharge valve from being closed by the water. The damming pressure may be produced by water entering and being dammed in a closed space which is disposed above the diaphragm and communicates by a passage with the sprinkler pipe a.

Filed: 1940-10-25
Abstract: 544,924. Alternating-current machines. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 25, 1940, No. 15713. Convention date, Oct. 25, 1939. [Class 35] In a machine, such as a squirrel cage induction motor having a stator winding in slots, the motor has slots with inner and outer portions circumferentially displaced from each other for conductors of different sections, these slots being all simultaneously alignable with the stator slots and the displacement being such that the inner and outer conductor portion each form continuous conductor passages longitudinally through the rotor. An improved start-to-run characteristic is thereby obtained, magnetic locking is prevented and magnetic noise is reduced. Fig. 1 shows a machine with a slotted stator 10 and a rotor with inclined slots containing small section outer conductors 20 joined by narrow portions 22 to large section inner conductors 21, the conductors being connected to end rings 23 and formed either by casting or by separate bars. Materials of different resistivities may be used for the inner and outer bars. In Fig. 2 a rotor is shown in which alternate packets of similar laminae are reversed, as shown by dotted lines, so that the outer and inner conductors 26, 27 run continuously throughout the rotor length while the outer ends of the slots and conductors and the neck portions 28 are discontinuous. In another form, Fig. 3, the large inner conductors 27 are radial, and the amount of offset of the necks 29 leading to the small outer conductors 26 exceeds one slot pitch by a fraction of a pitch so that each conductor 27 is connected to two conductors 26. Alternate packets of laminae are reversed, as shown in dotted lines, with the result that at the crossing points 30 of the necks a number of small section conductors is formed which, together with the conductors 26, 27, extend continuously along the whole core. Specification 544,923 is referred to.
