IPC: H02M7/40
Filed: 1942-06-23
Abstract: 558,381. Converting. WIDAKOWICH, M. June 23, 1942, No. 12260/43. Divided out of and addition to 558,358. [Class 38 (ii)] In a converting system according to the parent Specification, an E.M.F. is produced in a circuit parallel to the series contactor S and/or in a circuit of the parallel contactor P so as to allow the contactor to switch over when no current is flowing. Fig. 5 shows one arrangement involving a condenser 2 which is normally short-circuited by a synchronously operated switch PI but is brought into circuit just before the contactor P opens thereby cutting down the current through P substantially to zero at the moment P opens. In a modification, Fig. 10, the condenser 2 is made inactive at desired times by means of a pre-excited transformer or transductor 1, 3 fed from suitable inner points of the primary winding PR of the converter transformer. Fig. 15 shows another form in which instead of a condenser being used, the auxiliary voltage is applied to a winding 40. The Figure shows a three phase system with two valves V1, V2 for each phase for full-wave rectification. Current impulses may also be applied to each phase before it divides as in Fig. 15 and conversion of D.C. to A.C. is also described, Fig. 22 (not shown).

Patent GB-1100227-A (GB)
Title: An improved method of making a wash-and-wear wool-containing garment
IPC: D06C29/00
Filed: 1965-03-24
Abstract: Wool-containing garments are crease proofed and shrinkproofed and their resistance to fuzzing, pilling and localized cockling after laundering and air or tumble drying is improved by constructing them from chemically and mechanically stabilized fabric and dimensionally stable components, e.g. sewing thread, zippers, lining and pocketing material; waistband canvasses and tapes, wetting the fabric before or after making it into the garments with an aqueous solution of a water-soluble reducing agent, drying the fabric if the wetting is effected prior to garment manufacture, forming the garments into their desired configuration and steam-pressing and drying.  The fabrics may be chemically stabilized by treating them with an aqueous solution containing permonosulphuric acid and a wetting agent at 77 DEG F and then with an aqueous solution of sodium sulphite at 77 DEG F, by the application of less than 5% by weight of a suitable polymer such as polyhexamethylene sebacamide by interfacial polymerization or by treating them with a saturated sodium chloride solution at 110 DEG F, adding potassium permanganate until the bath's initial deep purple colouration turns brown due to water-insoluble manganese dioxide, replacing the bath by clear water and then applying a solution containing sodium bisulphite and acetic acid. The mechanical stabilization of the fabric comprises the removal of relaxation shrinkage by first drying on a single or multi-pass tenter dryer with maximum warp overfeed to prevent or eliminate warp relaxation shrinkage, rewetting and again drying using a conveyor dryer to prevent or eliminate filling relaxation shrinkage.  Suitable reducing agents are sodium sulphite, bisulphite and metabisulphite, monoethanolamine sulphite and bisulphite, ammonium thioglycollate and monoethanolamine thioglycollate.  The aqueous solution of the reducing agent may contain a wetting agent, e.g. an alkylaryl polyether alcohol. After wetting with the aqueous solution of the reducing agent the garment may be placed on a garment press and steam applied at least at 30 pounds per square inch gauge for 10-30 seconds, the garment press being maintained in a closed position for a further period, e.g. 45 seconds, without the application of steam and a vacuum being subsequently applied to the garment in the open press for drying.  Garments made from wool in admixture with nylon may be treated.  Specified garments are trousers, straight skirts, pleated skirts, shirts, slacks and suit coats.

Title: Improvements relating to the manufacture of yeast
IPC: C12N1/16
Filed: 1926-05-14
Abstract: 252,193. International Yeast Co., Ltd., (Assignees of Buhrig, W. H. F.). May 14, 1925, [Convention date]. Yeast.-In yeast-manufacturing processes involving the continuous addition of concentrated wort to the mash during fermentation, and the continuous withdrawal of yeast-containing liquor therefrom at the same rate, main and auxiliary fermenting vats are provided, the concentration of the wort being greater in the main than in the auxiliary vats. For example, a portion of a concentrated " sugar-salt " wort, prepared by the addition to clarified cane or beet molasses of yeast nutrients, such as inorganic ammonium salts, carbonates of sodium or calcium together with sulphuric, phosphoric or lactic acids, is diluted, in the main vat with water or wash liquors and seed yeast added. Throughout the resulting fermentation, which is carried out with aeration and with the addition of yeast nutrients and acidityadjusting substances, e.g. aqua ammonia, concentrated wort of the above nature is added continuously at such a rate as to raise the concentration approximately from 2‹ to 3‹ Balling. After about eight hours' withdrawal of the liquor into the auxiliary vat is commenced. The fermentation is continued in the auxiliary vat for about three hours coupled with reduction in concentration, by aeration-control or dilution, to about 2‹ Balling. Withdrawal of the yeast-bearing liquor from the auxiliary vat is then commenced and the uniform flow of the liquor through the two vats continues until all the concentrated liquor has been used and the main vat emptied. The yeast is separated, cooled, filtered and pressed in the usual manner. Small additions of seed yeast mav be made to the main vat at intervals of about eight hours.

Abstract: 1,044,331. Electric analogue calculating. AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY, MINISTRY OF INTERNATIONAL TRADE & INDUSTRY. April 1, 1963 [March 30, 1962; June 30, 1962; July 4, 1962], No. 12742/63. Heading G4G. In an analogue calculating bridge circuit, one arm of the bridge includes a semi-conductor exhibiting the magneto-resistance effect and the Hall effect, and means are provided for varying the magnetic field acting on the semiconductor. In Fig. 5, the bridge circuit is balanced with coil 7 and resistance 10 shortcircuited and with switch 21 open; the coil 7 and resistance 10 are then switched into the circuit. The voltage across the semi-conductor element 1 is proportional to the bridge current I and to the square of the magnetic field, and so is proportional to I<3>; the Hall electrode 8 introduces a term proportional to I<2>, a resistance 10 introduces a term proportional to I, and a battery 20 introduces a constant term. Thus the circuit solves the equation y = ax<3> + bx<2> + cx + d. In a modification, Fig. 8 (not shown), the magnetic field of coil 7 is supplemented by that of further coils fed with currents proportional to other variables; this solves the equation

Abstract: 190,435. Akt.-Ges. Brown, Boveri, et Cie. Dec. 20, 1921, [Convention date]. Master control systems; automatic starting systems; controllers, pneumatic operation.- Multiple unit controllers on electric trains are operated by compressed-air cylinders a<1>, a<2> furnished with electromagnetically-actuated valves d, e, one of which turns on compressed air when its magnet is energized, the other when its magnet is de-energized. A master controller S co-operating with hunting-switch brushcontacts i, h, j causes a rack b to be moved any selected r.umber of steps to the left from the zero position shown, the car controller being driven by a pinion c. Stoppage at the selected position is brought about by the agency of the hunting-switch contacts, which deenergize the magnet of the valve e, while preserving the energization of the valve d, causing the compressed air to act oppositely in the two cylinders. Automatic control of the rate of starting may be obtained by arranging the hunting-switch contacts in conjunction with a current-limit relay. In order to obviate deenergization of the valve magneto between successive contact positions of the hunting-switch, each magnet has two windings connected to overlapping contacts of the hunting-switch, so that the windings are in use alternately. In addition a push-button relay may be provided to allow the driver to continue the movement of the rack in single steps.
