Filed: 1937-11-11
Abstract: 507,479. Converting. I. G. FARBEN. INDUSTRIE AKT.-GES., and JOHNSON, G. W. Nov. 11, 1937, No. 31022. [Class 38 (ii)] An A.C. furnace in which the arc burns in an atmosphere of hydrocarbon, is supplied with direct current from an A.C. circuit through a rectifier employing discharge devices having immersion igniter control, the output of the rectifier being controlled in dependence on variations in the arc current to give stability of operation. In the form shown in Fig. 1 the ignition impulses for the discharge device J are derived from a circuit comprising a supply transformer C, saturable choke D and unilaterally conductive device E. Control in dependence on the arc current is obtained by introducing a biassing voltage into the circuit at H from a current transformer A and rectifier bridge B, in opposition to a constant biassing voltage introduced at G. In a modification this control circuit is employed to control an auxiliary grid controlled rectifier and ignition impulses for the main rectifier are derived from a current transformer connected in the anode circuit of the auxiliary rectifier. This auxiliary rectifier may also be controlled by means of any of the arrangements described in Specification 418,971.

Title: Improvements in and relating to automatic record changers for gramophones
IPC: G11B17/16
Filed: 1935-04-18
Abstract: 454,337. Magazine gramophones. COMPARE, A., 26, Alandale Drive, Pinner, Middlesex. April 18, 1935, No. 31200. Divided out of 439,106. [Class 40 (ii)] Relates to magazine gramophones of the kind in which the records are supported above the turntable by a vertical post from which they are dropped in turn on to the turntable, for playing. According to the invention, the magazine post embodies two parts, formed respectively with a shoulder and an abutment, and is so mounted that one part may be moved relatively to the other, first so that the post constitutes a smooth spindle on which a stack of records may easily be threaded, and then into a position in which the shoulder forms a support under the lowest record and in which the abutment is located just above the top surface of that record ; release of the lowest record from the post is effected by moving it laterally, whilst the abutment prevents lateral movement of the other records. The construction and operation of a machine embodying the invention are described in Specification 439,106. In a modified form of record-release mechanism, shown in the Figure instead of an offset base being provided on the end of a movable bell-crank lever, a base 113 is carried by fixed arms 312, disposed between the arms 318 of a member 218<a>. A central finger 118, as well as the part 218<a>, is pivoted at 112<a>, and when the members 118, 218<a> rock into their normal position, as shown, the base 113, which lies above the turntable spindle 110, provides the shoulder 114. When the part 218<a> is moved, against the action of a spring 316, so as to align the arms 318 with the base 113, the finger 118 is similarly moved by an extension 218<b> of the member 218<a> so that the assemblage then forms a smooth post on which the records can easily be threaded. The top record of a pile thus located on the post acts upon a crank (not shown), which turns a spindle 323 into the position shown in the Figure, allowing the spring 316 to move the members of the post into position for retaining the records.

Title: Improvements in the treatment of waste laundry effluents
IPC: C02F1/52
Filed: 1946-10-23
Abstract: A process for the treatment of laundry waste and other soap-bearing trade effluents consists in adding to the effluent a reagent or reagents to precipitate the dissolved soap and/or to effect coagulation or de-emulsification of the suspended matter, screening or filtering the treated effluent, contacting the filtrate with ion-exchange materials to effect the complete or partial removal of the dissolved constituents, and conserving the heat of the effluent throughout all stages of treatment so as to reduce the temperature drop between the treated and untreated effluent to a low figure.  The reagent or reagents used for the precipitation of the soap and/or the coagulation or de-emulsification of the suspended matter may be a base, basic salt or salt of a metal or metals metals which form an insoluble soap and/or react with the contained sodium carbonate to form a carbonate, basic carbonate, hydroxide or oxide which acts as a coagulant or de-emulsifying agent.  According to one method aluminium sulphate is added to the laundry effluent to precipitate the dissolved soap as insoluble aluminium soap and to form aluminium hydroxide to coagulate or de-emulsify this soap and suspended matter. After filtration through a stainless steel filter cloth part of filtrate is passed through a bed of hydrogen-ion exchange material (e.g. a phenol sulphonate condensation product) and then mixed with the remainder of the filtrate to neutralize the sodium carbonate, leaving a relatively warm water with reduced dissolved salt content for re-use, roughly equivalent to the initial water.  If the materials being laundered contain excessive amounts of soluble inorganic matter, or cations or anions build up as a result of re-using the treated effluent, the whole or part of the sodium salts other than carbonate may be removed by passing the whole or part of the acid effluent leaving the cation-exchange column through a column of anion exchange material (e.g. a dicyandiamide-melamine condensation product) yielding an effluent substantially free from dissolved salts.  The material recovered from the filter, containing aluminium soap and hydroxide, yields insoluble fatty p  acid and soluble aluminium sulphate on treatment with sulphonic acid.  The cation-exchange material may be regenerated by treatment with sulphuric acid.  Further examples are given in the Specification. The temperature of the effluent is reduced during the process from about 65 DEG C. to 40 DEG  or 50 DEG C.  Specification 622,495 is referred to.  According to the Provisional Specification an organic coagulant or de-emulsifying agent such as a pectate or alginate may be added separately before the inorganic reagent.

Abstract: 341,527. Photo-electric cells. ARCTURUS RADIO TUBE CO., 260, Sherman Avenue, Newark, New Jersey, U.S.A.- (Assignees of Ruben, S. ; 801, Riverside Drive, New York, U.S.A.) Oct. 17, 1929, No. 31599. Convention date, Oct. 18, 1928. [Class 39 (i).] A photo-electric cell has a thermionic cathode and a light-sensitive control electrode having its surface formed of a light-sensitive compound of the oxygen series of the sixth periodic group, for example silver sulphide or selenide, or molybdenum sulphide. As shown the cell has a filament cathode 1, an anode 2 and a control electrode A of copper sensitized as already described. Variations in light to which the control electrode is exposed produce variations in the resistance and consequently, in the potential of the electrode. The necessary crystalline structure of the compound may be obtained by heating the metal in a vapour such as sulphur, selenium or tellurium. A high resistance electrode, with large crystals, may be produced by slow cooling.
