Title: Improvements in or relating to electric arc converters
IPC: H02M7/04
Filed: 1935-12-13
Abstract: 469,010. Converting; synchronous alternators. GENERAL ELECTRIC CO., Ltd., and TAYLOUR, H. H. Dec. 13, 1935, No. 34619. [Classes 35 and 38 (ii)] In an electric arc converter 4 of the parallel type commutation is effected by voltage from an auxiliary source 1 controlled in accordance with load current. The source 1 is a dynamoelectric generator driven by a synchronous motor 12 from the A.C. input or output circuit 13 and is connected in series with the primary of the transformer 10 supplying the converter. The generator 1 has only one stator slot per pole per phase so that it generates impulses, and each pole is composed of two parts arranged axially on the machine. One of these parts 6 is narrow and rectangular and the other 7 is wedge shaped. Both parts carry an exciting winding 2 energized from the mains 13 and proportioned so that saw-toothed impulses of fixed amplitude are generated in the stator windings 8. The rectangular sectioned part of each pole also carries a winding 3 carrying load current so that flat-topped impulses varying with load current are generated. The resultant of these two effects gives the commutating voltage. The coupling between the motor 12 and the generator 1 may be adjustable or the stators of the machines 1 or 12 may be adjustable or the excitation of the motor 12 may be varied to vary the phase of the injected commutating voltage. A reversing switch 18 ensures the same polarity of the bus-bars 17 during rectification and inversion and the current through the series winding 3 is reversed during the change-over. Specification 437,669 is referred to.

Abstract: 433,293. Electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of St. Louis, J. A. ; 25, Park Street, Montclair, New Jersey, U.S.A.) Dec. 13, 1933, No. 35094. Convention date, Dec. 13, 1932. [Class 38 (v)] An electromagne. tically - operatec vacuum switch having a small amount of free movement between the arma. ture and the mov able contact in order that in opening the armature may deliver a light hammer blow to the contact and separate the contacts in case of freezing or sticking between them has the movable contact carried by the operating member supporting the armature, this contact being hingedly connected to the operating member. As shown in Figs. 1, 2 and 3 the switch is mounted within an evacuated or inert gasfilled envelope and has a fixed contact 4, formed by bending the wire as shown in Fig. 3 and secured to the inlead 2 on which normally rests a movable contact wire 9 pivoted to a supporting wire 8. The armature 10, which is of semi-circular section is welded to the wire 5 near its free end, this wire being formed with a helix 7 between the armature and the point at which it is secured to the inlead 3 and having a downturned end 6 formed with a slotted loop through which the movable contact wire projects. Thus the weight of the armature normally holds the wire 9 on the fixed contact 4, but on energization of the electromagnet 12 the armature is raised to withdraw the movable contact 9 from the fixed contact 4, its supporting wire permitting motion by flexure of the helix 7. During this movement the armature has initially a small amount of free movement so that it separates the contacts with a light hammer blow and, if the contacts are welded together slightly, effects their separation with certainty. The parts are restored to the positions shown on de-energization of the controlling electromagnet. A flexible lead 11 is provided to conduct current to the movable contact. The armature may, alternatively, be controlled by a permanent magnet. Specification 404,112 is referred to.

Abstract: 966,238. Semi-conductor devices. MICROWAVE ASSOCIATES Inc. Oct. 4, 1961 [Nov. 14, 1960], No. 35827/61. Drawings to Specification. Heading H1K. A device has a junction-containing semiconductor body with a protective housing consisting of glass with a melting-point above 600� C. and which is sealed directly to at least that part of the surface of the body where the junction meets the surface. In embodiments in which the housing is to extend over the leads to the device the leads are attached prior to the glassing operation. The lead material is chosen to have a similar coefficient of expansion to that of the glass. In the case of silicon bodies the leads may be ohmically attached using a gold/ silicon alloy. Since this is low melting the leads must be held in a jig until first the glass and then the alloy solidify. If high-melting platinum/silicon or nickel-silicon alloys are used no jig is required since the leads remain firmly attached during the glassing operation. Nickel/ silicon alloys may be produced in situ by plating the body with nickel and then heating, in contact with the lead. In embodiments in which the ends of the body are left exposed, for example to facilitate cooling during operation, the leads may be attached after glassing using the low melting gold/silicon alloys. The glass housing is generally made by firing a coating of glass frit, preferably of borosilicate material, made into a paste, for example with a nitrocellulose binder and amyl acetate and which has been brushed on to the body. The paste is fired at 700-750� C. until a glaze appears indicating elimination of organic material and the formation of a continuous vitreous cut. With suitable glasses such as the borosilicate materials described heating is preferably continued until devitrification occurs resulting in a partially crystalline structure. Various silicon diodes are described with reference to the Figures (not shown), many of these being mesa diodes. Similar diodes have also been made of germanium, and other semi-conductors may be used. It is stated that transistors may be provided with similar housings.
