IPC: H02M7/06
Filed: 1926-11-20
Abstract: 261,785. Akt.-Ges. Brown Boveri, et Cie. Nov. 21, 1925, [Convention date]. Heating systems. - A furnace using a direct current arc is fed by a mercury vapour rectifier having sufficient reactance in its alternating current circuit to steady the arc. Fig. 1 shows a transformer T coupled to the rectifier G and furnace F and having a steadying choke D in its primary circuit. Fig. 2 shows a polyphase arrangement having choke coils and wound on cores D which also carry shunt a.nd compounding direct current windings. A modification employs a transformer having its leakage reactance increased by magnetic shunts, the permeability of the dispersion paths being varied by direct current windings fed from the rectifier.

Abstract: 478,342. Photographic cameras. BILLING, N. P. May 16, 1936, No. 29755/34. [Class 98 (i)] The scale indications on the shutter mechanism, the exposure meter and the diaphragm stops of a photographic camera are formed by or obtained from the terms of geometrical progression so that a simple calculation determines the correct shutter setting for any particular exposure meter scale reading. The camera comprises a casing 1 and telescopic sections 2, 3. In the section 3 are mounted two discs, one carrying diaphragm apertures, the other carrying colour filters. In the apertures 6, 7 are shown indications representing the stop and filter in use. The exposure meter comprise a graduated wedge 8 viewed through the finder 9 and bearing scale markings. The markings on the scale 13 correspond with exposure times <1>/500 sec., <1>/250 ... 1 sec., 2 secs. &c., and may take the form of a geometrical series 1, 2, 4, 8, &c., or an arithmetical series 1, 2, 3, 4, &c. The interchangeable stops correspond to apertures f/3À5, f/4À5, f/6À3, &c., and are represented by similar series. The exposure meter scales and filter indications are also based on similar progressions. Consequently the calculations are conducted by simple multiplication or addition for the geometrical and arithmetical series scales respectively. Specifications 423,035, 423,226, 428,455, and 428,511 are referred to.

Title: Improvements in or relating to the production of semi-conductor bodies
Inventor: BRADSHAW STANLEY EDWIN
IPC: C30B15/04
Filed: 1955-10-18
Abstract: <PICT:0797377/III/1> A molten mass of semi-conductor is progressively solidified in a continuously evacuated enclosure, the loss by evaporation of a significant impurity being made good by passing vapour of the impurity from a separate source into contact with the molten material.  In the Figure silicon is kept in the crucible 7 at a temperature electrically regulated to be 30 DEG  C. above the melting point, the whole vessel being evacuated to 10-5 to 10-6 mm. mercury via the pipe 5.  After about an hour the impurities have evaporated and a seed crystal 30 is dipped into the melt and slowly raised to draw up the silicon in the form of a single crystal.  To ensure that this is of low-resistivity n-type, phosphorus vapour is introduced from the bulb 27 via the tube 25 throughout the growth of the crystal.  During the previous evaporation of impurities phosphorus is prevented from entering by cooling the bulb 27 in liquid air.  Specification 779,179, [Group XXXVI], is referred to.

Abstract: 781,138. Kinematograph cameras. TECHNICOLOR MOTION PICTURE CORPORATION. Oct. 20, 1955 [Nov. 8, 1954], No. 29987/55. Class 97(1) In a kinematograph camera in which the film gate and the associated film feed mechanism are moved, transversely to the direction of feed, out of the optical axis so that the image formed by the objective can be observed, a stop holds the film gate and film feed carriage in the exposure position and a switch in the circuit of the film drive motor is opened when the stop is moved from the holding position. Preferably, handle 71 for moving the carriage C carrying intermittent film feed mechanism 42, film gate 40 in plate 41 and ground glass screen 46, and handle 79 for retracting and advancing plunger 74 are interlocked so that carriage C cannot be moved until plunger 74 has been withdrawn from the path of block 72. Handle 71 may then be pulled outwards, past recess 83 in the hub of rotatable handle 79, thus turning pinion 62 to lower the carriage C by means of rack 61 (Fig. 5). and bringing ground glass screen 46 into the optical axis of objective 8 so that it can be viewed by a co-axial sight tube (Figs. 1 and 2, not shown). Splined shaft 54 sliding through gear 53 transmits the shutter and intermittent feed drive from gear 51 to gear 56 and to shutter 47 and intermittent feed mechanism 42. Rack 61 moves in a dove-tail guide in bracket 29 and guide surfaces 33 slide on surfaces provided on bracket 36. On returning handle 71 to the inward position, the carriage C is raised and, on rotating handle 79, finger 88 on shaft 78 turning pinion 77 does not close motor switch 86, to render the film drive motor energizable, until the movement of the wedge surface of plunger 74 has brought stops 60 into contact with stops 65 and the top of rack 61 into contact with stop 63.

[Class 80 (ii)] [Also in Groups XXV and XXVIII] A connection for securing a member 4 provided with a helical rib 3 to another member 13 comprises a coil 5 fitting between the turns of the rib and projecting radially beyond the rib to form an abutment for a threaded sleeve 10 screwing into a socket 9 in member 13. Member 4 extends into a bore 7 in member 13, the inner end of the coil bearing against a shoulder 8. When member 10 is tightened, the coil, which is preferably of mild or spring steel wire, clamps the rib 3 and prevents relative rotation of members 4, 13, but when member 10 is loosened, axial adjustment between members 4, 13 may be effected by screwing member 4 through the coil. The invention is applicable generally, but as described member 13 is a driving or driven member and 4 is a power transmission shaft, for example of the type disclosed in Specification 380,204.
