Abstract: MANICURING UNIT                ABSTRACT OF THE DISCLOSURE         A portable, battery-operated manicuring machine is disclosed in which the batteries and the final output shaft are aligned substantially coaxially. The  motor and actuating switch are positioned within the housing intermediate the battery chamber and  the final drive unit with the motor being  radially  offset from the axis of alignment of the drive unit, batteries and housing and the switch being positioned diametrically opposite the motor. The drive between the motor and the final  output shaft includes a gear reduction train comprising a pinion gear on the motor output shaft, a cluster gear having it larger-diameter gear in meshing relationship with the pinion gear and its smaller gear in meshing relationship with an internally-toothed gear and the output shaft.         The motor and gear-reduction train are mounted on opposite sides of a bulkhead which is mounted transversely within the forward part of the machine housing. The motor is mounted by means of a pressed fit in the bulkhead and is retained therein by a yoke engaging the remote surfaces of the motor and the bulkhead.         The output speed and the diameter of the manicure accessories are correlated to provide a slow surface speed of the working surface in the order of 23 inches per second.          A speed of 360 rpm is preferred as is an outside diameter of 1.20 inches.     This application is a divisional of Canadian Patent Application Serial No. 264,837 filed November 3rd, 1976.

Abstract: EMBRITTLEMENT ADDITIVE FOR TREATING ORGANIC MATERIALS                        ABSTRACT OF THE DISCLOSURE           In a process for treating the organic fraction of solid waste and cellulosic material with acid to form an embrittled material reducible to a powdered material, increased embrittle-ment and grinding efficiency are obtained by including an embrit-tlement additive with the acid.  The embrittlement additive is a quaternary ammonium compound.  Increased efficiency is evidenced by a decrease in embrittlement temperature and an increase in the amount of embrittled material which will pass through a 40 mesh screen after grinding.  The resulting product has a wide variety of uses including as a fuel, a fuel in combination with other fuels, as a building material and as a chemical feed stock, among other things.

Abstract: MOUNTING, AND PACKAGING, OF SILICON DEVICES ON CERAMIC SUBSTRATES, AND ASSEMBLIES CONTAINING                SILICON DEVICES          Abstract of the Disclosure Mounting silicon devices on a ceramic substrate creates considerable problems when the device has a geometry, such as being very long relative to its width, due to flatness and thermal mismatches.  In the present invention a thin silicon substrate is interposed between base and device, the substrate of a geometry which reduces flatness and thermal mismatching to acceptable levels.  Also the use of a silicon substrate enables well developed and easily provided silicon technology to form conductor patterns for interconnecting between device and base, avoiding problems of producing such conductor patterns on the ceramic base,  The invention is particularly useful for the mounting of linear devices, such as linear imagers, which can have a length to width ratio in excess of 20:1.                             - i -
