Title: Improvements relating to interpoles for commutator dynamo electric machines
IPC: H02K23/24
Filed: 1938-01-21
Abstract: 508,872. Dynamo-electric machines. TUSTIN, A., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Jan. 21, 1938, No. 2121. [Class 35] In a commutator dynamo-electric machine having interpoles, a coil is provided at the side of an interpole linking the leakage flux from the interpole to the adjacent parts of the machine and connected in a closed series circuit with a second coil surrounding the interpole and linking with the working flux from the interpole to the armature, the coils being proportioned and arranged so that the current set up in the first coil due to a change in leakage flux consequent upon a change in the excitation of the interpole will be greater than the current set up in the second coil by the change in the working flux of the interpole whereby the current from the first coil will circulate through the second coil in a direction to assist the change in the working flux. In machines intended to rotate in both directions, coils 4, 6, Fig. 3, on opposite sides of an interpole are connected in closed series circuit with a coil 5 surrounding the interpole. The coils may be formed from a single strip or they may be in two pieces joined together as shown in Fig. 5.

Title: Improvements in or relating to apparatus for stopping run-away trams in mines and other places
IPC: B61B12/06
Filed: 1923-01-24
Abstract: 214,713. Hadfields, Ltd., and Rodgers, I. Jan. 24, 1923. Track apparatus for stopping trains. - Railroad vehicles travelling above a predetermined speed, e.g. trucks running away on a gradient, are stopped by means of a hook a, which is automatically raised into engagement with a truck axle p, the hook being connected to a cable v drawn from a storage drum x to which an increasing brake-pressure is applied as the cable unwinds. Normally, the hook a is in a lowered or inoperative, position, supported on a table b carried by the upper end of a cylinder c slidably mounted on a hollow pillar d and retained in its lowered position, against the pressure of a spring housed within the pillar d, by a pivoted detent g the lower end of which engages a nose h on the cylinder c. A pivoted arm o the lower end of which carries an adjustable weight s extends into the path of the axles &c. of the truck. At normal speeds the impacts of the axles give the arm o a limited idle swinging movement, but when the speed exceeds the predetermined limit the arm o is moved to an extent whereby its lower end is driven against the upper end of detent g. The cylinder c is thus released and is raised by the spring to bring the hook a into operative position. As the cable v is drawn from the drum x, a worm gear 5, 6 driven through gear wheels 2, 3 from the drum axle, causes an arm 13 to exert an increasing pressure on a brake-band 8 which retards unwinding of the cable. A contact arm 14, also operated by the worm gear 5, 6, closes an alarm circuit 15 to give a warning to the engineman and to the station nearest to the apparatus.

Abstract: 1,099,057. Producing metal articles. GENERAL ELECTRIC CO. Jan. 21, 1966 [Jan. 21, 1965], No. 2813/66. Heading B3A. [Also in Division H1] A method of separating a number of magnetic elements held together in adjacent relation comprises surrounding the outer edge of the elements with electrcal conductor means and generating at least one current surge in the conductor means to separate the elements by the forces created by the current surge. In the manufacture of magnetic cores stacks of laminations are annealed prior to final alignment and securement and during annealing a metallic bond is created between adjacent laminations. A stack of stator laminations 11 is placed on a stud 62 within the confines of an excitation winding 21, which comprises coil groups 24-29 defining poles of alternating polarity. The winding 21 is connected to an electrical energy source 50 which comprises a capacitor bank charged to a selected voltage regulated by a variable transformer (Fig. 8, not shown). When the capacitor bank is discharged a surge of electrical energy is injected into the winding 21 and an electromagnetic field is distributed around the periphery of the laminations 11. The forces produced by the field break the interlaminate bonds to separate the laminations from each other. The laminations may be aligned and welded together before annealing and the method of the invention may be used to break down at least partially the interlaminate bonds.
