Title: Apparatus and method for changing relative positions of movable conductors of an electrical inductive device
IPC: H02K15/06
Filed: 1967-04-24
Abstract: 1,130,665. Electromagnetic forming of coils. GENERAL ELECTRIC CO. 24 April, 1967 [28 July, 1966], No. 18732/67. Headings B3A and B3Q. A method of effecting a placement of a coil relative to a dynamo-electric machine core having a bore with a plurality of axially extending slots comprises placing the coil in a circuit for energization from an A.C. source and selectively applying to the circuit at least a portion of a sinusoidal pulse from the A.C. source for a preselected interval to provide a current flow in the coil to effect the desired placement. A stator core 17 having loosely wound coils 13, 14, 15 (position A) of a main winding 25 is placed over a cylindrical fixture 30, which is made of a diamagnetic material such as copper or aluminium. The core is held by members 31, 32 with a flat side 33 of the core engaging an adjacent flat side on the member 32 to prevent rotation. The fixture 30 preferably has an insulating sleeve 34, which may be an integral part of the fixture or it may be inserted first in the bore to retain the windings in the slots. Leads 36, 37 of the winding 25 are connected to a sinusoidal pulse generating circuit 40, which in turn may be connected to a commercial alternating supply 43. When an ignitron 44 is switched on, the sum of the source voltage and the voltage across the secondary winding S of a variable transformer T is applied to the winding 25. The ignitron firing circuit switches on the ignitron at a predetermined point in a halfcycle of the A.C. supply to apply a portion of at least one pulse from the current source. The current flow in the winding 25 establishes a varying magnetic field, which induces eddy currents in the fixture 30. These eddy currents create a magnetic field that increases the intensity of the field around the extremities of the tooth sections (21) of the core, Fig. 2 (not shown). In an alternative embodiment a fixture 51 having a winding 52 replaces the fixture 30. When a switch 59 is in the position shown in Fig. 5 a pulse from a circuit 40 is supplied to the stator winding 54 and a current flow is induced in the winding 52. When the switch 59 is moved to the position shown in dashed outline, the winding 52 is connected to the circuit 40 and current flow is induced in the stator winding 54 by inductive coupling between the windings 52, 54. Rotation of the core is prevented by a support member as in Fig. 1 and in the case of the fixture 51, it is mounted on a rigidly supported shaft 60.

Title: Improvements in automatic valves
IPC: F04F1/02
Filed: 1920-07-06
Abstract: 146,888. Maass, O. April 15, 1918, [Convention date]. Mercury pumps.-A liquid seal valve device particularly applicable for use in connexion with T÷pler mercury vacuum pumps comprises a U- tube containing mercury and provided at each end with reservoirs, an intermediate point of one leg being by-passed to one reservoir which is bypassed to the other. The reservoir 14 is connected to the limb 12 by an inverted bend 12<1> which is connected to atmosphere either directly by a valve-controlled pipe 20 or through a mercury seal 26 by a valve-controlled tube 28. A valve-controlled filling aperture 30 and a drain cock 31 are provided for varying the height of the seal 26. The reservoir 14 is coupled to a point 15 on the limb 12 by an inverted bend 17, and to the reservoir 13 on the limb 11 by a pipe 18, dipping into the reservoir and controlled by a valve 24. The apparatus is connected with an exhauster by a valve-controlled conduit 19, and to the apparatus in which alternations of pressure are required by a pipe 32. Normally, mercury stands at the level e - - e in the U-tube and d in the reservoir 14. When suction is admitted the levels alter to f, f, f, f and continued suction empties the pipe 18 permitting atmospheric pressure if valve 22 is open or sub-atmospheric 'pressure if valve 29 is open to obtain in the reservoir 13 and pipe 32. This allows the mercury to assume the level c - - c in the U-tube, which causes a volume of mercury to siphon through 17 to restore the level d. The time during which suction operates in the pipe 32 is controlled by a valve or constriction 24 in the pipe 18, while the time during which release occurs is controlled by a valve or constriction 23 in the limb 11. Reference has been directed by the Comptroller to Specification 16561/08.

Filed: 1920-07-06
Abstract: 146,990. Western Electric Co., (Assignees of Morehouse, L. F.). Dec. 4, 1918, [Convention date]. Addition to 146,520, [Class 40 (iii), Telegraphs &c.]. Ciphers.-In a cipher telegraph system of the kind described in the parent Specification, two or more ciphering-machines are employed operating conjointly through a set of relays with a machine upon which the unciphered message is set up. The ciphering characters on the looped tape are different in number from those on the tape of the other machine in order to avoid repetition of the ciphering combinations set up by the two machines. A keyboard or tape machine A, Fig. 1, operated by the unciphered message controls selectively contacts 1 .. 5 connected to the terminals of selecting magnets 1<d> .. 5<d> respectively. The other terminals of the magnets 1<d> .. 5<d> are connected to the armatures 11 .. 15 of relavs 1<c> .. 5<c>. The circuits of the windings of the relays 1<c> .. 5<c> are controlled by a tape machine X through which a looped ciphering tape is run and by a tape machine Y through which a looped ciphering tape is run. The cipher characters in the tape passing through the machine X are different in number from the characters in the tape passing through the machine Y. If the character J is passing through the machine A at the same time as the character O is passing through the machine X and the character R through the machine Y the relays 1<c> .. 5<c> are operated in accordance with the character L and the magnets 1<d> .. 5<d> in accordance with the character B. When the ciphered tape is passed through a machine A simultaneously with the passage of looped ciphering tapes through the machines X and Y the message is de-ciphered. To decipher the message as it is received over the line, a line relay 41, Fig. 2, energized in accordance with the current impulses of the ciphered message operates in conjunction with a rotary distributor D to the contact segments 1<1> .. 5<1> to which the magnets. 1<d> .. 5d are connected.
