Abstract: 338,545. Foss, L., and Foss, R. July 15, 1929. Translucent paper; paper, treating with special materials. - A method of making translucent parchment consists in dipping paper into a heated mixture of linseed oil, reinforced Japan oil, and turpentine. After drying, the treated paper is coated with a pyroxylin or other quick drying cement that remains transparent after drying, a stiff brush being used to produce a rough stippled effect during drying. Configurations are then outlined by means of pyroxylin or other coloured paints applied by means of a spray gun and stencils. Raised lines of dark pyroxylin cement or other pasty material are then applied to the outlines by means of a lining gun employing compressed air. When the relief work is dry a coating of burnt umber ground in oil is applied, and immediately rubbed off so as to fill the crevices and to polish the raised portions. Before this coating dries, powdered stone is rubbed into it to produce an antique effect.

Abstract: 240,432. Soc. Anon. des Etablissements Neu, (Assignees of Kestner & Neu). Sept. 24, 1924, [Convention date]. Cleaning, fluid-pressure processes for.-In an installation for the pneumatic removal and hydraulic conveyance of soot, cinders, &c., a chamber into which water is sprayed is interposed in the path of the current of air or gas charged with the soot &c. at a point between the intake and the suction-creating device the soot &c. precipitated being carried away to a discharge point at a distance by the water in the form of mud. The suction tubes 2, 22 arranged at the point in the boiler 1 where the soot collects and in the chimney flue 21 are connected by a pipe 6 to a tangential inlet in the lower part of a precipitating chamber 7, from the top of which a pipe 8 leads to the suction side of a fan 5. The gyratory motion thus imparted to the gases entering the chamber 7 causes a preliminary separation of the soot, further separation being affected by a spray of water from a central atomizer 17, the spray from which is conical and plays upon the whole conical surface 11 of the chamber 7, and final separation by atomizers 18 emitting finer-particles of water than the atomizer 17 and arranged to act over the whole of the part 9 of the chamber 7. The clean gas may be delivered by the fan into the fire-box of the boiler by a pipe 19, or it may be used for other purposes. The soot &c. mixed with water in the form of a thin mud or sludge is drawn off from the lower cone 12 of the chamber 7, which is of larger angle than the part 11, and is conveyed by a pipe 16 to the place of discharge, e.g. a sewer. Transportation may be effected by gravity or with the aid of an injector or pump at 20. The same fan 5 and the chamber 7 may be connected to several points in the boiler or a number of boilers, and to portable intake tubes in the smoke flues.

Abstract: 860,725. Transistor amplifier circuits. EVERSHED & VIGNOLES Ltd. July 6, 1959 [July 11, 1958], No. 22354/58. Class 40 (6). A transistor D.C. amplifier includes two transistor circuits arranged to respond to opposite half-cycles of alternating supply voltage, an input signal being supplied to one or both transistors in such a manner as to affect the transistor output currents unequally, and an output circuit which combines the transistor output signals so that leakage components tend to cancel but not the components representing the input signal. In the Figure an alternating current supply is applied to terminals 1 and 2 so that on one half-cycle current flows through rectifier 8 and a transistor circuit comprising a smoothing capacitor 21, a resistor 15 and transistor 4 and thus through rectifier 10 to the other supply terminal while on the other halfcycle current flows through rectifier 9, a transistor circuit comprising smoothing capacitor 20, resistor 15 and transistor 3 and thus through rectifier 7 to terminal 1. An output transformer 16 is coupled in series with the supply so that as the circuit is balanced the leakage currents balance out. If, however, the transistors are unbalanced due to the application of a signal to the base of transistor 4 or in push-pull to the bases of the two transistors an unequal current flows on the two half-cycles producing an output from the transformer. This output is passed through a phase-sensitive rectifier circuit 31 to output terminals 34, 35. Resistor 15 helps to equalize the leakage current and also increases the amount of unbalance due to the signal. It could alternatively be replaced by separate resistors in leads 5 and 6. The amplifier could be used in the inventions described in Specifications 799,864 and 811,325.
