Title: Improvements in and relating to electric machine drives
IPC: H02P5/68
Filed: 1931-11-17
Abstract: 391,239. Maintaining equal speeds of motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. - (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl- Ufer, Berlin.) Nov. 17, 1931, No. 31890. Convention date, Nov. 17, 1930. [Class 38 (iii).] With auxiliary starting motor. - A group of motors M1, M2, M3 driving the separate sections of a printing press and coupled to synchronizing asynchronous motors A1, A2, A3, are provided with an auxiliary motor H1, for operation of the press at inching speed. The motor H1 drives the motors A1, M1 through an overtaking coupling, and the leading motor A1 forces the other motors A2, A3, to which it is connected in parallel on the stator and rotor sides, to run in synchronism. The motors H1, A2, A3 are assisted by the motors M1, M2, M3, which are switched on, with armature resistance W1 in circuit, at the same time as the motor H1. When high speed is required the resistance W1 is slowly removed and the motor H1 is overtaken. Synchronous machines may replace the machines A1, A2, A3 and if the number of sectional motors in a group is large several leading motors may be used. The motors A1, M1, A2, M2, A3, M3 may be constructed in pairs within a common casing. The driving motors may be asynchronous machines interconnected for synchronizing, in which case a slip resistance is permanently inserted. A similar group of machines M4, M5, M6; A4, A5, A6, and H2 may be coupled to the first by closing a switch S, and the motors H1, H2 may also be synchronized.

Class 98 (1) In a between-thelens shutter a scale ring callibrated in shutter speeds including both those for which the shutter can be set and those of longer duration is couplable with the diaphragm aperture scale ring for maintaining any selected relative position. of the rings and a shutter speed setting ring carries a coupling member automatically engaging either the shutter speed scale ring or a stationary front cover plate and changing from one to the other at a fixed point in the travel of the scale ring. From the shortest exposure time to the longest settable time, lug 26 on shutter speed setting ring 12 is carried in a notch in scale ring 5, thereafter, as the shutter is adjusted for "bulb" operation, lug 26 strikes an abutment on fixed cover plate 23 and is removed from the notch in the scale ring and pressed by the rim of the scale ring into notch 29 in fixed plate 23. The adjustment for "bulb" operation is thus retained throughout the range of longer shutter speeds. Ring 12 may be of spring steel sheet and lug 26 formed thereon or, alternatively (Fig. 7, not shown) attached thereto. Specifications 744,962, 769,081 and 776,582 are referred to.

[Class 59.] Ball and like mills.-A method of manufacturing metallic powders from small metal particles for use as bronze colours consists in flattening the metal particles, for example by steel balls 15 in a drum 12, supplying fresh material at one end of the mill, withdrawing the treated particles at the other by means of an inert gas or air current, and separating the treated material outside the mill, the unfinished material passing back to the mill. The powder may be initially flattened in a ball mill 4 provided with large steel balls 5, the powder being fed to the mill by a worm 2 from a hopper 1. The mill 4 is provided with screens 6, 7, the ground material being raised by arms 9 and deposited into a shoot 11 for delivery through a pipe 10 to the mill 12. The mill 12 is provided with small balls 15 and with end screens 13, 14. A current of air or inert gas is forced by the fan 16 through pipes 17, 10 to the mill 12 and carries the ground material through pipe 18 to a sifter 20 comprising inclined plates 21 over which the ground material falls, the fine particles being carried by the air current to the cyclone 26 whilst the coarse particles pass back to the mill through the pipe 29. Grease may be added to the powder to prevent the ground particles adhering to one another. Further separation of the ground material may be provided for in the removable receptacle 27 by means of sieves. Filters may be inserted between the pipe 28 and cyclone 26 to remove any metal particles passing out of the cyclone. A sieve device may be used with the wind sifter or the sieve device may be used alone. Specification 204,055, [Class 59, Grinding, crushing, &c.], is referred to.

Title: Improvements in and relating to automatic controls for defrosting refrigerator evaporators
IPC: F25D21/00
Filed: 1952-12-19
Abstract: 731,970. Valves. GENERAL ELECTRIC CO. Dec. 19, 1952 [Dec. 19, 1951], No. 32262/52. Class 135. [Also in Group XXXVII] A refrigerator control comprises an operating arm 8 pivoted at 9, a second arm 39 and a spring 40 between the arms for holding them in spaced relationship, a temperature-responsive element 11 to move the arms as a unit against a spring 13 during normal operation to stop and start refrigeration, a rotatable structure 24 including a cam 25 and ratchet 26, a pawl 30 on arm 8 for engaging the ratchet to advance the ratchet and cam on movement of the arm 8 to its refrigeration - starting position, and locking means effective after predetermined rotation of the cam for engaging the cam to initiate a defrost period, the element 11 effecting movement of arm 39 relative to arm 8 until it engages the locking means when a predetermined temperature is reached to shift the locking means to again allow movement of the structure whereby the defrost period is ended. The lever 39 is held a constant distance from arm 8 by the adjustable spring 40, spread being limited by a stop 42. A spring 18 causes the arm 8 to snap from one position to the other to operate switch contacts or a valve closure member 5 controlling the supply of refrigerant to the evaporator. The arm 8 terminates in a yoke 7 and the valve stem carries a permanent magnet 6 which is attracted towards the adjacent arm of the yoke. The pawl 30 advances the ratchet by one tooth each time the arm is moved down to snap the valve open, and pawl 32 prevents clockwise rotation of the ratchet. After a number of movements of the arm, a cam follower 36 drops into a notch 33 in the cam under the action of spring 38, and prevents movement of the arm to open the valve. Thus, the temperature rises to defrost the evaporator and when it reaches a predetermined high value, the element 11 moves the lever 39 to shift follower 36 out of the notch by its end 43, whereupon the arm moves down to open the valve and simultaneously turns the cam to move the notch out of alignment with the follower. A member 47 fixed to the yoke limits movement of the arm 8 by engaging the cam and an adjustable stop 48, and also acts as a brake to prevent overtravel of the cam. Specification 695,850, [Group XXXVII], is referred to.
