Title: Improvements in or relating to alternating current rectifier circuits employing imperfect valves
IPC: H02M7/06
Filed: 1929-02-04
Abstract: 314,939. Weyandt, C. S. July 5, 1928, [Convention date]. Static contact rectifiers and electrolytic cells, arrangements of. - Relates to circuit arrangements involving asymmetric conducting devices such as copper-cuprous oxide rectifiers, electrolytic cells, and similar imperfect valves permitting appreciable inverse flow of current when used for supplying a D.C. load from an A.C. source, and consists in providing in the load circuit an inductance, the reactance of which is many times greater than the ohmic resistance of the load circuit, thus causing the current in the low resistance direction to persist for a greater portion of a complete cycle and thereby reducing heating of the rectifier by inverse current. Where the useful load comprises an inductive winding as for example in the case of a bell or a reciprocating motor comprising an armature c, Fig. 1<a>, reciprocated by windings L, L<1> energized through oppositely connected groups of rectifiers V, the load itself may provide the necessary reactance. Where the load is non-inductive, however, as in the case of a battery under charge or an arc for welding as shown in Fig. 2, an open or closed core inductance L is connected in series with the load. Current density in the rectifier elements is kept below 0.5 amperes per square inch of surface, groups of rectifiers being connected in parallel if necessary. Forced cooling, for example by means of air jets 2 may be employed. Reference has been directed by the Comptroller to Specifications 249,669, 259,537, 282,693, 284,325; and 289,866, as open to inspection under Sect. 91 (3) (a).

Abstract: 858,700. Stud and socket fastenings; hooks. UNITED-CARR FASTENER CORPORATION. Nov. 24, 1958 [Nov. 25, 1957], No. 37809/58. Classes 44 and 89(2). A fastening-device for attachment to an apertured-support comprises an outer-element 10 having a body for entering the aperture from one side of the support and a shoulder for bearing on said one side of the support, an inner-element 14 journalled in the outer-element, the two elements having portions 20, 24, spaced from the shoulder on the body of the outer-element and extending laterally outwardly beyond the body, the rotatable relationship of the elements permitting the two portions when adjacent one another to be introduced through the aperture to extend beneath the opposite-side of the support, the portions after subsequent relativerotation of the elements abutting said oppositesides of the support on opposite-sides of the aperture. The support may consist of two plates N, F, as shown, or a single plate. The two portions are in the form of hooks and the hook of the outer-element has teeth 26 to impede rotation of the element relative to the support. The two elements are prevented from axial-displacement by a lug 18 on the inner-element which engages the end having the hook of the outer-element, the other-end of the inner-element having a flange 16 which bears on a flange 12 of the outer-element. The flange 12 forms the shoulder which bears on the face of the support remote from the face engaged by the hooks. Rotation of the two elements beyond the position in which the hooks are opposite each other is prevented by the lug 18 engaging the hook of the outer-element. The inner-element has a wall at the flanged-end which has a straightsided-depression 30 by which the element can be turned relative to the outer-element. When the device is attached to a single plate, the innerelement has means for supporting an article such as a coat-hook, or hanger-hook for wires or a pipe e.g.

Abstract: Hydrocarbons are purified by treatment with acid under conditions of concentration, temperature, pressure, and duration such that sulphonation is avoided and the liquid polymerization products are insoluble in the acid and remain dissolved in the hydrocarbon, from which they are recovered by distillation.  In the case of sulphuric acid the concentration is always less than 60 DEG  B<\>ae, acid of 46-48 DEG  B<\>ae being preferably used with heat. Phosphoric acid may also be used.  For example, heavy solvent naphtha is treated with 10 per cent of its weight of phosphoric acid of density 1.70 or of sulphuric acid of 46-48 DEG  B<\>ae at a temperature of 110 DEG  C. for several hours.  The acid is then drawn off, the solution neutralized and distilled in steam, yielding a viscous oil and a substance which may be used as varnish.  The treatment of xylene, benzene, toluene, and light tar oil is also described.  The process is also applicable to aliphatic hydrocarbons if these do not contain large quantities of aromatic derivatives.ALSO:Hydrocarbons are purified by treatment with and under conditions of concentration, temperature, pressure, and duration such that sulphonation is avoided and the liquid polymerization p  products are insoluble in the acid and remain dissolved in the hydrocarbon, from which they are recovered by distillation.
