Abstract: A B S T R A C T           An improvement in the treatment and purification of waste materials or refuse/sewage sludge mixtures by composting and also by thermal retting, whereby the waste material is crushed and the non-compostable constituents are extracted by sifting of the reduced waste.  The material, ready-treated for composting and of a predetermined particle size, is heaped layer upon layer to form a stack.  In the interior of the stack, longitudinal tunnel-like hollow courses are provided at floor level, possibly with further channel-like passages above.  Spaced vertical flue-like vents 5 are provided at various points and the hollow courses and channel-like passages are open at least at one extremity.  The stacked material is left undisturbed until the compost has matured.

Abstract: ABSTRACT OF THE DISCLOSURE           A circuit for demodulating a composite stereo signal of the type including a main-channel (L+R) signal and a sub-channel (L-R) signal to derive therefrom individual channel information signals L and Rs respectively.  A switching circuit of the balanced-modulator type is supplied with composite stereo signal at one set of input terminals and with a switching signal whose frequency is equal to the sub-carrier onto which the sub-channel (L-R) signal is modulated, at another set of input terminals.  The switching circuit produces oppositely-phased sub-channel signals which are applied to first and second current generators, respectively.  An amplifier is supplied with the composite stereo signal to amplify the main-channel (L+R) sig-nal, the amplifier including a channel separation control to adjustably vary the currents flowing through the amplifier so as to correspondingly vary the main-channel (L+R) currents.  The main-channel currents produced by the amplifier and the oppositely-phased sub-channel currents produced by the current generators are supplied to respective output terminals whereat they are combined to produce the separate channel information signals L and R with minimum crosstalk.

Abstract: ABSTRACT            Fuel saving apparatus for controlling the supply of fuel to one or more selected cylinders of a multi-cylinder internal combustion engine comprises a remotely and independently controlled fuel saving valve operably posi-tioned to provide selective communication between the cylinder clearance volume and a filtered air portion of the engine carburetor.  The valve is closed for normal, full power engine operation, and open for predetermined low engine power demand periods.  The opening of said valve so severely reduces cylinder intake vacuum and resultant air-fuel influx as to render temporarily ineffective the cylinder, thereby reducing engine fuel consumption.

Abstract: A B S T R A C T Copper sulfide in the presence or absence of metallic copper contained in a dross obtained from the copper drossing of lead bullion is separated from metal-lic lead entrained or occluded in the dross by introducing the dross into a vessel other than a reverberatory furnace, usually a kettle, also introducing an alkali metal sulfide, preferably sodium sulfide, into the kettle, and heating the dross and alkali metal sulfide together in the kettle at an elevated temperature not in excess of 1200°F. and for a time sufficient to melt together the dross and alkali metal sulfide.  The thus-obtained molten dross releases the entrained molten lead which falls to the bottom of the kettle.  The molten dross and molten alkali metal sulfide form a low melting copper sulfide-alkali metal sulfide matte on the surface of the resulting pool of the released molten lead, and the matte is separated from the molten lead pool, for instance by being lifted off the pool by means of a hook positioned in the matte layer while molten and retained in the matte layer while the matte layer is permitted to solidify on the molten lead pool surface.          Copper sulfide in the presence of metallic copper can also be separated from metallic lead and tin contained in solder drosses, e.g. high tin-bearing solder drosses, or in other drosses in accordance with this invention.
