Title: Improvements in and relating to control systems for synchronous electric motors
IPC: H02K19/00
Filed: 1936-04-23
Abstract: 473,981. Control of A.C. motors. BRITISH THOMSON - HOUSTON CO., Ltd., and WALKER, J. H. April 23, 1936, No. 11616. [Class 38 (iii)] For producing a large synchronizing torque in the synchronous motor M of a synchronous motor alternator set at starting, and for producing a phase shift of the alternator volts with respect to the supply volts during running, an induction regulator having a primary winding R1, and a secondary winding R2 is connected to boost the voltage applied to the synchronous motor during starting and is then reconnected by means of a switch P to operate as a phase-shifting transformer between the supply L and the motor M during running. With the switch P closed on to contacts A, B, C, for starting the secondary winding R2 of the induction regulator is connected between the motor M and the supply L. The regulator, which first bucks the supply voltage, is then operated to reduce the buck and then to boost the voltage. The boost of the regulator is increased, and then the switch P is thrown quickly over to the contacts K, L, M, to disconnect the winding R2 from the supply and connect it in star, for the running operation. To avoid disconnecting the motor M from the supply during the changeover, the change may be made in steps by means of the switch P. The first step is to open the contact C so that the motor M runs on a single phase connection, followed by the closure of contacts L and M, the motor M being fed single phase through the induction regulator and from the supply. The contacts A and B are then opened, so that the motor is fed single phase through the regulator only, and then the contact K is closed to give the running connections.

Abstract: 377,213. Supply systems ; phase changing. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Blume, L. F. ; 15, Arlington Street, Pittsfield, Massachusetts, U.S.A.) April 20, 1931, No. 11697. Convention date, Aug. 19, 1930. [Classes 38 (ii) and 38 (iv).] Boosting by static transformers. - Voltage regulation of a three-phase circuit is obtained by transforming the threephase voltage to a two-phase voltage, regulating this by adjustable tappings on secondary windings of the transformers and feeding back into the threephase circuit by means of other transformers. Across the three lines A, B, C of the threephase circuit, three windings are connected in star formation, two of the windings forming the primary 10 of a transformer 14 and the third, the primary 11 of a transformer 12. Selected voltage tappings are taken from the transformers 12, 14 and fed into two windings on each of two boosting transformers on cores 35, 40. Secondary windings on each of these transformers are connected in series and with a line of the three-phase circuit, e.g. 47, 48 with C<1>, a third winding 44 on the transformer 35 alone being in series with the line A<1>, and the number of turns of this winding arranged so that its magnitude and phase difference is equivalent to that of the other two windings. The resulting three-phase voltage system A<1>, B<1>, C<1> is thus adjustable in value and phase rotation by suitable selection of tapping points. In order to facilitate tap changing and to prevent excessive distortion of the voltage, contact breakers C, B, are introduced between the tapping points.

Title: Semiconductor
IPC: H01L21/00
Filed: 1962-03-27
Abstract: Silicon and phosphorus are co-deposited on to a silicon core and the coated core is zone-melted one or more times in a vacuum at a rate of travel of 3 mm./min. to produce an n-type single crystal having a resistivity of 0,1-100 ohm/cm.  An overlayer of pure silicon may be deposited before zone melting. Co-deposition may be effected by passing a stream of hydrogen over liquid silicochloroform, adding a mixture of trichlorosilane and phosphorus trichloride dropwise to the vaporized silicochloroform, and passing the resulting mixture over a silicon core heated electrically at 1150  DEG C.

Abstract: 854,815. Photo-electric control systems. LOVE, J. April 14, 1959 [April 14, 1958], No. 11864/58. Class 40(3). [Also in Groups XXII and XXXIII] A method of reinforcing an aircraft fuselage comprises winding fine wire of high tensile strength about the fuselage at intervals along its length thereby to form, at such intervals, encircling ribbons each comprising a number of turns of the wire, and securing such wire turns to one another and to the fuselage by means of an adhesive. To wind wire 1 around an aircraft fuselage 24, two semi circular frame sections 8, 9 are moved, on wheels 11 to surround the fuselage and are lifted into position by jacks 12. The two sections 8, 9 together form a circular track 13, 14 along which a carriage 15, on wheels 16, 17, is driven by a motor 18, supplied with current through brushes 50, 51 engaging slip rings 48, 49 on the frame, the motor driving a pinion 20 engaging a circular rack 21 on the frame. Alternatively the carriage may be coupled to a driving ring formed in two parts, carried by the frame and rotated by a suitable motor. Wire from a spool 23 on the carriage 15 passes over a jockey pulley on a pivoted arm 25 cooperating with a brake 27 so that increased tension in the wire moves the arm 25 down against a spring 28 and releases the brake to decrease the tension in the wire. The wire is laid on the fuselage, with adjacent turns touching, by a fork 29 which is moved axially of the fuselage, as the carriage 15 moves there-around, by a threaded shaft 32 rotated through gearing 36, 38 by the motor 18. A fine control of the fork 29 is effected by a motor 39 rotating, through a worm 40, an exteriorly threaded bearing sleeve 42 of the shaft 32. The motor 39 is controlled by a pair of photo electric cells 43, 44 carried by the fork 29 and adapted to respond equally to an image of a preceding wire turn portion 45, illuminated by a light source 46, when the fork is correctly positioned for laying the corresponding portion of a succeeding wire turn to ensure that succeeding turns are in contact.

Title: Improvements relating to the sealing of metal wires into vitreous envelopes
IPC: C03C27/02
Filed: 1936-04-30
Abstract: 474,394. Sealing wires into vitreous material. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. April 30, 1936, No. 12318. [Class 36] A leading-in wire of refractory and ductile metal or alloy is prepared for sealing into vitreous material by mechanically reducing its thickness over a portion of its length to form a foliation, and subjecting the foliation to an acid process whereby the thickness is further reduced so that at least a portion extending transversely across the whole of the foliation does not exceed the maximum thickness which permits an hermetic seal to be made. This thickness in the case of a quartz to metal seal may be taken as 0À02 mm. The flattening may be effected by a hammering or punching process and, for a molybdenum wire, the acid bath for effecting the further reduction to the requisite thickness comprises a mixture of equal parts of nitric acid, sulphuric acid and water. This eroding process tends to leave the edges of the foliation very thin, thereby facilitating the production of a good seal. The wire with the foliation is inserted into a narrow bore vitreous tube, which may be a constriction at the end of a discharge lamp, the tube is exhausted and the wire heated to drive off occluded gases, and finally the tube surrounding the foliation is heated until it collapses on to the foliation.
