Patent GB-197155-A (GB)
Title: Improvements in or relating to electric induction furnaces
IPC: H05B6/06
Filed: 1922-03-31
Abstract: 197,155. Vacuumschmelze Ges., and Rohn, W. March 31, 1922. Induction furnaces.-In induction furnaces for melting cold scrap, an initial voltage several times greater than the normal is initially produced in the charge to start the melting, without increasing the size of the transformer core, by supplying current to the primary windings of a much higher frequency and higher voltage per coil than the normal, the supply of the high frequency current being switched off and replaced by normal frequency current when melting is obtained. A high frequency of 500-1000 alternations per second is referred to. This method removes the necessity for having a closed metal ring or rings in the melting channel or for leaving part of the molten metal from the previous charge therein. The frequency of the primary current may be reduced in steps to the normal frequency as the conductivity of the charge increases by using stationary frequency converters, the number of primary coils being increased at each step by using a primary coil having tappings or a subdivided primary coil. In a modification, the high and low frequency currents are used simultaneously, two or more primary coils or a subdivided primary coil being used and suitable devices such as choking coils or electric valves being fitted to prefevent interference in the primary circuits. The energy supplied to the high frequency circuit is only a small fraction of the total energy employed. The furnace in which the process is used may be worked at a pressure other than atmospheric.

Filed: 1926-04-09
Abstract: 251,257. Semer Ges., W., and Kraus, F. April 24, 1925, [Convention date]. Commutator switching - arrangement.-In a commutator switch rectifier in which the moving contacts e, f are carried on a vibrating spring arm c actuated by an electromagnet b energized by the alternating current, an adjustable stop i is provided on one side of the spring arm so as to limit the effective length of the spring during its movement in the direction y away from the magnet whilst the whole length of the spring is effective during its attraction towards the magnet poles a in the direction x. The sparing as a whole is turned to vibrate with a total period corresponding to the period of the alternating current, and in order to prevent sparking with variation of voltage an adjustable magnetic shunt p is provided between the pole pieces a of the magnet to enable the strength of the impulses imparted to the spring to be maintained constant on different voltages. According to a modification the stop i may be employed as one of the rectifier contacts. The direct current load is connected between the spring and the mid point of a transformer secondary winding, the ends of which are connected to the fixed contacts of the device.

Title: Asynchronous electric cascade generator
IPC: H02K17/38
Filed: 1930-03-25
Abstract: 353,489. Induction machines. FORGES ET ATELIERS DE CONSTRUCTION ELECTRIQUES DE JEUMONT, 75, Boulevard Haussmann, Paris. March 25, 1930, No. 9503. Convention date, April 16, 1929. [Class 35.] In an asynchronous generator group comprising an induction machine cascaded with a single frequency changer of commutator type or a double or two-part frequency changer of commutator type, the resultant voltage which the frequency changer supplies to the induction machine is varied in magnitude and phase by varying the two component voltages suppled to the frequency changer. Fig. 1 shows the use of two induction regulators R1, R2 the secondary windings of which supply separate voltage components to the slip-rings B1, B2 of a double frequency changer arranged in cascade with an induction generator, as described in Specification 292,465. Alternatively, both terminals of the secondary windings may be brought out on each phase, thus involving six slip-rings on each frequency converter. In the form shown in Fig. 5, the induction regulators R1, R2 give equal voltages and the secondary side of one of them is connected to the secondary of a transformer T, the secondary voltage of which is dephased by ninety electrical degrees from that of the regulators. In place of a two-part frequency changer a single one may be used, the slip-rings of which are connected to the secondaries of the induction regulators in threephase, as shown in Fig. 3, or in six-phase by means of six brushes. A transformer corresponding to that shown at T in Fig. 1 may also be used in connection with a single frequency changer. The frequency changers may have compensating and commutating windings on their stators and constitute a group running at constant power, in which case the induction regulator or regulators furnish only the magnetizing power required by the frequency changers. Specification 292,465, [Class 35, Dynamo-electric generators &c.], is referred to.

Abstract: 624,489. Glass-to-metal seals. STANDARD TELEPHONES & CABLES, Ltd. April 11, 1947, No. 9717. Convention date, June 21, 1946. [Class 36] An electric terminal member 1 is sealed through an aperture in a metallic supporting member 3 by means of a glass seal 7 which fills the aperture and extends along the terminal member 1 on both sides of the aperture for a distance d which is greater than the radius r of the glass at the aperture. The support member 3 is shaped at the aperture to form an inwardly protruding flange 5 having a lip 6. The rod 1 is inserted through the bore of a glass cylinder 26, Fig. 5, and into the bore 46 of a refractory block 23, e.g. of carbon, the glass resting in the aperture. The block 23 is then placed in an oven and the glass softened to a point where it flows slightly to take up the shape shown by the dotted lines 30, 31 and fill the annular space 29 of the support member. The glass seals to the rod which is the hottest part since it seats on the oven platform. Alternatively the refractory block may be in two parts, one above and one below the member 3, and may be hollowed out to form a mould of the desired shape. In this case the glass cylinder is actually melted in its lower portions and takes the shape of the mould, while the upper portion is only softened and thus only droops slightly to give a convex surface. A portion of the upper part of the rod 1 is masked so that the glass only seals to the rod below this portion. The supporting member 3 may have a curved beading around the aperture to give some flexibility against accidental knocking. The metal parts may be made of a nickel-iron alloy.

Abstract: Soft capsulated compositions containing on aqueous medicament, consist of a water-in-oil emulsion enclosed in a soft capsule, the emulsion and the continuous oil phase having a viscosity such that migration of the globules of the water phase is substantially prevented at the storage temperature used for the capsule.  The viscosity of the emulsion is at least 6000 cps. at 20 DEG C. at a shear rate of 1 sec-1. and that of the oil and that of the oil phase is at least 100 cps. at 20 DEG C. at high shear rate. Suitable oils are minerals oils, preferably liquid paraffin; vegetable oils such as arachis, olive, sesame, soya bean, castor and cattonseed oils; oily esters such as ethyl oleate, dilutyl sebacate, or isoamyl salicylate; or a suitable silicone oil.  If required, thickening agents, such as soft yellow or white paraffin, hard paraffin, beeswax, wool fats and alcohols, micro-crystalline paraffin hydrocarbons, vegetable stearines, hydrogenated vegetable fats, ethyl cellulose, or polyvalent metal, soaps, may be included to give the aid phase the necessary shear rate.  Also emusifying agents, preferably of the non-ionic type, may be added the capsule compositions are particularly suitable for making up aqueous oral vaccines.
