Abstract: METHOD AND APPARATUS FOR MAKING A SHEET MOLDING COMPOUND                  Abstract of the Disclosure A method and apparatus for making a sheet molding compound.  A thickened uncured thermosetting resin mix is supplied as a thin coating to a sheet of plastic film and chopped fibers are deposited on the resin film to provide a composite laminate.  The side edges of the plastic film are then folded inwardly in a double fold and the laminate is wound in coiled form.  Kneading rolls having ribbed surfaces ride against the coiled laminate to provide a thorough impregnation of the resin and fibers.  The sheet molding compound of the invention utilizes only a single sheet of plastic film, thereby providing a substan-tial cost saving over conventional systems using a pair of plastic films.  The folded edge on the plastic film serves to confine the resin and fibers during kneading, and the second or reverse fold provides a projecting tab to facilitate removal of the plastic film at the time of use.

Abstract: ABSTRACT OF THE DISCLOSURE   A novel process is provided for the separation of components of base metal (e.g. Sb, Sn, Pb, Zn, Cu, N1, Fe or As) and silver from precious metal components in mineral concentrates.  The process comprises reacting together gaseous hydrogen and chlorine so as to produce a flame providing a reaction zone having a temperature in excess of 900°C to 2500°C and passing into the reaction zone of the flame the mineral concentrate in finely divided particulate form.  In this reaction, the silver and base metal in the concentrate are converted into their volatile chlorides, while the precious metal components in the concentrate remain in a solid, water-insolu-ble form.  This enables the facile separation of the silver and base metal chlorides from the water insoluble solids in the reaction product.

Abstract: Abstract of the Disclosure Whenever power fails, an audio signal is produced by an oscilla?or, which includes a pair of transistors of opposite conductivity having the collector of each connected to the base of the other and is maintained in an off condition as long as the power is on. When the oscillator is turned on, a rapidly changing surge of current is supplied from a battery, which has a capacitor in parallel therewith, to an audio producing device in the discharge path of the oscillator.  This surge of current is produced through utilizing a Zener diode between the battery and one of the two transistors of the oscillator.  The parallel combination of a resistor and a capacitor is disposed between the Zener diode and the transistors of the oscillator.  A resistor also is disposed between the emitter of the transistor initially turned on and a capacitor, which is charged to a potential to turn on the transistor. This resistor is of substantially lower impedance than a resistor between the capacitor and the battery.  This arrangement increases the power at least two orders of magnitude.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved nephelometer for immunochemical complex assay measures forward light scatter in samples.  The angle of forward scatter, about 30°, is small enough to result in a large amount of forward scatter from the immunochemical complex particles which are to be assayed, whose size is of the order of the wave length of the light used in the optical system.  Forward scattering from smaller particles, such as from molecules of buffer, antibody and serum, is constant during the course of a test, and is compensated for by the use of subtraction circuits which are readily and semiautomatically adjusted to subtract proper values, in accordance with the readings taken on standard or "blank" samples of buffer, antibody and serum.  Forward scattering from large particles, such as dust, is variable, and results in fluctuating signals, which are electrically processed to ignore the spurious peaks.  The results of a test are displayed on a digital read out meter.         Also described is a method of and protocol for immuno-chemical assay, whereby the amount of antigen originally present in a sample is determined by adding a known amount of antibody, and by assaying the "blank" component ingredients and the resulting mixture.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved adsorption-desorption process is provided for separating gaseous mixtures.  The process includes the old steps of passing a stream of crude gaseous mixture under superatmospheric pressure through a first adsorber; then withdrawing from said first adsorber a stream of product gas  depleted in undesired component; then switching the stream of crude gaseous mixture to a second adsorber when the impurity concentration at a given location before the exhaust end of the first absorber exceeds a given value in the gas; then, after the crude gas stream is switched away from said first adsorber, decompressing the first adsorber in at least one decompression stage to release residual product gas therefrom; and finally employing said residual product gas to re-pressurize an adsorber.  The improvement comprises: conducting the decompressing in at least two separate decompres-sion stages; then collecting the residual product gas from each decompression stage in separate storage vessels; then with-drawing residual product gas from one storage vessel and purging the decompressed adsorber to desorb undesired impurities therefrom; and finally withdrawing residual product gas from another of said storage vessels and partially re-pressurizing the purged adsorber therewith.  This system requires less valving, is simpler and is less expensive to operate.

Abstract: ABSTRACT     A rotary, sliding vane compressor is provided with means for supplying a relatively small, predetermined quantity of an incompressible fluid, such as lubricating oil, under-neath the vanes. The fluid is injected at a point while the vanes are collapsing within the vane pockets formed within the rotor and is trapped underneath the vane during its movement to the contact point thereby resisting the collapse of the vane so as to hold the vane tip in continuous engagement with the stator surface in the compression cavity.  The means for supplying the fluid underneath said vanes includes a device for interrupting flow of lubricant from a sump to the interior of the compressor housing thereby controlling or metering the lubricant and also preventing reverse rotation of the compressor rotor caused by oil pressure under the vanes forcing the vane tips to follow the curvature of the cylinder wall in a backward direction.  Means are also provided for relieving the suction created when the vanes move outwardly in their vane slots during startup and for draining any liquid trapped under the vanes.  A relief groove is milled into the face of one of the end plates and affords communication between the vane slot and a zone of higher pressure fluid.

Abstract: PRINTING SYSTEM HAVING A HOT ROLL        FUSER WITH A scraping BLADE CLEANER             Abstract of the Disclosure In a xerographic printing system the toned copy paper is fused by the pressure nip formed by a hot roll and a backup roll.  A scraping blade engages the destructible surface of the backup roll at a critical angle which is selected as a function of the coefficients of friction of the backup roll's surface and the toner/debris contamina-tion that may be collected on the backup roll's surface.  As a result, the blade slides freely on the roll's surface, but does not slide on the surface of the toner/debris contamination film.          This film forms a locking angle with the blade, placing the blade in stress, and developing a film removing chisel-like action therewith.
