Abstract: 388,292. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. July 18, 1932, No. 20320. Convention date, April 26. [Class 40 (v).] The grid bias of a valve amplifier varies with the signal volume, the bias becoming so much more negative as the volume diminishes that the sum of the bias and the signal voltage is practically constant. In this way the consumption of plate current is reduced and the efficiency increased. In Fig. 1, an electrolytic or other rectifier 3 is connected across the input coil 2 in series with two condensers 4, 5, and resistances 6, 7 are connected as shown. Permanent bias is supplied by a battery 8 whilst the rectified signal gives an opposing bias to the grid of the amplifier 1. In Fig. 2, the output of the amplifier 1 is divided by a condenser potentiometer 20, 21 and part is applied to a grid-leak rectifier 12. Rising signal strength gives increased positive voltage.on the plate of this rectifier, part of which is transferred to the. grid of the valve 1 through a potentiometer 14, 15, 16. Permanent bias is supplied by a battery 17, and alternating voltages are smoothed out by condensers 18, 19. In a third form, Fig. 3 (not shown), the battery 17 is replaced by a diode rectifier connected to a mains supply and the grid-leak rectifier 12 is replaced by a second diode rectifier, bothrectifiers being contained in a single envelope with a common cathode.

Title: Improvements in or connected with the extraction of fatty and other matters by meansof volatile solvents
IPC: C11B1/10
Filed: 1922-07-27
Abstract: 186,040. Zipser, S. Sept. 10, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Fats and fatty oils, extracting by solvents.- In the extraction of fats and other matters by volatile solvents, air is excluded and the varying pressure due to the movement of fluids in the plant is corrected by the flow of water into or out of a tank connected to the separator of the condensed steam and solvent. Water may also be run from the tank to reduce the pressure throughout the plant, and any gas, such as air admitted during charging of the extractors, containing vapour not liquefied by the condenser is returned to a freshly-charged and preferably evacuated extractor for absorption of the vapours by the charge. In the apparatus shown for use with a solvent lighter than water, the water tank B<1> is provided with a valved water inlet pipe l<1> and and outlet g<1> with valved branches d<1>, d<3>; it is connected by a pipe c<1> with water-separator W<1> which is connected by a pipe f<1> to a solvent reservoir L<1> and by a pipe a' to the condenser K<1>. Pipe n<1> fitted with valve m<1> leads to the extractors, and pipe o fitted with valve o<1> leads to solvent or extract containers. Liquid-level indicators are shown at s. When solvent is withdrawn from the reservoir L' by the pipe e<1> there is a. flow of solvent from W<1> to L<1> and of water from B<1> to W<1> and from l<1 >to B<1>. As the condenser K<1> discharges, the liquid water and solvent pass through pipe a<1> to the separator W<1>, the gases and uncondensed vapours bv pipes a<1> and b<1> to the top of the separator W<1> and the reservoir L<1> causing a, flow of solvent from L<1> to W and of water from W<1> to B<1> and from B' through pipes g<1>, d<1>. A reduced pressure throughout the plant is caused by closing valve h<1> and opening valve h<2>. The gases and uncondensed vapours are expelled from the tanks W<1>, L' through pipes b<1>, n<1> to condense the vapours on a fresh charge in an evacuated extractor by admitting water through the pipe l<1> while pipes e<1>, o are closed. The vessel W<1> may be used as both separator and reservoir, vessel L' being omitted. A modified plant for use with solvents heavier than water is described. The invention is especially applicable to the extraction plant described in Specification 183,825. The process can be employed in connection with the distillation by steam of fatty acids or other substances not miscible with water.

Title: Method of producing mineral fibres insulating compositions
IPC: C04B26/22
Filed: 1943-12-09
Abstract: A binder for mineral fibre insulating compositions comprises an extract of pine wood resin which is substantially insoluble in petroleum hydrocarbon.  Glass, mineral wool, rock wool or asbestos, may be treated with the material which is prepared from pine wood by extracting with a coal tar hydrocarbon, e.g. benzol or toluol, freeing the extract of volatile constituents and extracting the resin with a petroleum hydrocarbon, e.g., gasoline, leaving a residue which is low in abietic acid content. Alternatively, the residue of the initial benzol extraction is treated with a mixture of gasoline and furfural, the furfural layer separated and the solvent evaporated. The resin is defoamed by steaming or heat treatment.  The resin may be pulverised, dusted into the mineral fibres and fluxed by heating, or it may be applied in solution or emulsified in water with casein, soya bean protein, animal glue or other protective colloid.  A mixture with a resin of lower melting point or in conjunction with a water soluble phenolic resin may be used in emulsion.  In an example, glass wool bats are dipped in the emulsion and dried at 60 DEG C. or heated for 20 minutes at 165 DEG C.  Glass wool may also be sprayed with a dilute solution of the pine wood resin and castor oil in ethyl alcohol.  Long-fibred asbestos may be similarly treated. The pine wood resin extract may be applied in solution, in a spray, as an emulsion or a suspension, or in hot melt condition and may comprise 5-25 per cent. by weight of the insulating composition, preferably 5-15 per cent.  The insulating material may be in the form of blankets, rolls or sheets and may be moulded.  They are to be used in refrigerators, coolers, houses, air conditioning plant, railroad cars, tanks, ships, &c. Specifications 541,670, [Group VIII], and 582,986 are referred to.
