A single-phase to threephase converting arrangement has a circuit comprising two impedances of different kinds connected across the single-phase terminals, the arrangement being such that the vector BD (Fig. 2) representing the voltage across one impedance (inductance 17, in Fig. 1) leads by 30 degrees the vector CD representing the supply voltage, the vector CB representing the voltage across the other impedance (resistance 18, 19, in Fig. 1) lags 60 degrees, CB is made equal in magnitude to CA, which represents a voltage taken from the supply by means of, for example, a tapped transformer winding 12 (Fig. 1), so that the vectors AB, BC, AC represent a balanced threephase voltage. As the resistance and inductance cannot be purely resistive and inductive two adjustments are necessary. The resistance is made adjustable, and one point of connection to the transformer secondary is adjustable by means of a sliding contact, a number of tappings, or a potentiometer connected across part or all of the winding as shown.

Abstract: 427,889. Vapour burners. EHRICH & GRAETZ AKT.-GES., 90, Elsenstrasse, Berlin. Oct. 20, 1933, No. 29108. Convention date, Dec. 31, 1932. [Class 75 (i)] In a vapour burner in which liquid fuel is supplied by a thermal pump through an air vessel to the vaporizer the air vessel is heated by the burner otherwise than by conduction of heat from the vaporizer so that the inlet end of the vaporizer may be kept cool and the deposition of carbon in the vaporizer minimized. Fig. 1 shows an incandescent vapour lamp in which a thermal pump 2 heated by an auxiliary burner 9 on the U-shaped mixing tube 8 supplies fuel past a valve 4 through an air vessel 5 to a vaporizer 7 having a superheater loop 10 arranged above the burner between the limbs of the mixing tube. The upper part of the air vessel 5 projects through a wind-protection plate 13 into the path of the hot combustion gases escaping from the chimney 11 below a roof cap 12. The pipe 6 connecting the air vessel to the vaporizer is of 5 m.m. or less diameter and it passes through the chimney jacket 11<a> to an open space surrounded by the annular fuel reservoir 1. Fig. 3 shows a radiator stove comprising a main burner 15 heating fireclay radiants 17 and the vaporizer 7<a>, an auxiliary burner 9 branched off the main burner heating the thermal pump 2 which supplies fuel from the reservoir 1<a> to the vaporizer 7<a> through an air vessel 5 having at its upper end a heat conductor 21 leading to near one of the radiants 17. A reflector 18 and screens 19, 20 protect the pump, air vessel, and reservoir against radiation from the radiants. Fig. 4 shows a hurricane lantern in which the air vessel 5 projects above the bottom 28 of the lantern and is heated by radiation from the burner. A branch pipe 9<c> leads from the mixing chamber to an auxiliary burner heating the thermal pump 2. The valve 4 may be mounted directly on the vaporizer 7<c>, the fuel pipe 6 being then dispensed with. The condenser tube of the thermal pump is enclosed in a chimney 25<c> having perforations at both ends. The Specification as open to inspection under Sect. 91 comprises also an open boiling or cooking stove shown in Fig. 4 (Cancelled) in which the thermal pump 2 and air vessel 5 are arranged in a casing 25 having ventilation holes 26. The stove burner comprises a large flame head 23 which may be shut off, a small flame head 24 heating the vaporizing chamber, and a tube 9<a> conveying combustible mixture to an auxiliary burner heating a tongue secured to the pump 2. The air vessel 5 receives its heat from the warm liquid coming from the pump and by conduction from the burner. This subjectmatter does not appear in the Specification as accepted.

[Class 37] Testing-apparatus for measuring the magnetic characteristics of samples of magnetic material having substantially differing dimensions comprises a yoke formed of two symmetrical halves A, B, one of which is displaceable on a stationary central bar d, while the other has a central bar e rigidly connected with it, magnetizing coils c for generating a magnetic flux in the yoke, and means such as a coil f for measuring the flux through the central bars. The piece g to be tested is placed in one of the gaps s between the side limbs of the yoke, and the useful flux coming from the piece g passes through the central bars d, e while the stray flux passes through the remaining gap t. If the coilf carries a current inversely proportional to the cross-sectional area of the test-piece g, the deflection, which may be measured by a pointer or by a mirror and source of light, is proportional to the induction in the test-piece. The strength of the field producing the induction may be measured by means of a coil i which is rotated by means of a synchronous motor in the vicinity of the testpiece, the alternating current induced in the coil being rectified and measured by a D.C. instrument.

Abstract: 1,197,407. Circuit assemblies. SIEMENS A.G. 20 June, 1968 [21 June, 1967], No. 29336/68. Heading H1R. [Also in Division B3] In a method of producing external connections on a sub-assembly as described in Specification 1,124,376 connections between conductors separated by a layer of insulating material are effected by energizing two welding electrodes and applying them under pressure to those points where connections are to be made. Electrical components and/or functional electric circuits embedded in a plastics material block 1 have their connecting wires terminating in connection points at one lateral surface of the block. Conductive paths 2 in a first layer of conductors are applied to the surface 7 to make connections with the connection points. A foil of thermoplastic material 3 provided on one with an adhesive and on the other side with a metal foil is placed over the conductors 2 and surface 7 and after hardening of the adhesive circuits 4 are formed by etching in the metal foil. In accordance with the invention connections between the conductors 2 and conductors 4 are made by positioning split welding electrodes 5, 6 at the place of interconnection, energizing them and applying pressure. The heat produced in conductor 4 first softens the insulating material 3 which is moved aside by the conductor 4 as it is pressed down and then when the conductors 4, 2 come into contact a weld is made. The conductors 4 may be applied chemically and reinforced by electroplating or by vaporizing or atomizing on metal. The conductors may be preformed. A plurality of insulating foils each carrying a printed circuit may be used.
