Abstract: Kit for preparing a package for dispensing solid products such as pills, said kit comprising:(1) at least one blister tray having a single compartment or an array of compartments, and(2) at least one sheet bearing an adhesive on one major surface thereof and having dimensions such that it is capable of covering said single compartment or said array of compartments. In another aspect of this invention, a plurality of the aformentioned sheets can be aggregated into a pad, from which the sheets can be conveniently dispensed.

Abstract: An electronic system for providing a stable, isochronous clock signal with very low jitter and slew rate to thereby permit multiplexing of data from an external source which is not synchronous with the multiplexer frame rate.

Abstract: A process for making alkylene carbonate by the reaction of carbon dioxide and an alkylene oxide of the formula ##STR1## wherein R, R.sub.1, R.sub.2 and R.sub.3 are one or more of hydrogen, alkyl, aryl, alkaryl, aralkyl, cycloalkyl, allyloxy, chloroalkyl, and aryloxy to produce the corresponding carbonate, which comprises:(a) providing a homogeneous liquid phase reaction zone in which the predominant material therein is the alkylene carbonate;(b) providing a catalytic amount of an alkylene oxide carbonation catalyst to said liquid phase;(c) having dissolved in said liquid phase sufficient CO.sub.2 to provide a molal amount therein which exceeds the molal amount of the catalyst;(d) providing a CO.sub.2 pressure in the reaction zone of between about 150 psig and about 750 psig;(e) maintaining a sufficient amount of the alkylene oxide in the reaction to maintain the pressure and temperature thereof;(f) maintaining the reaction zone at a temperature at which the alkylene oxide and CO.sub.

Abstract: The engine of a self-propelled combine is mounted in an enclosure having an inlet through which cooling air is drawn by an engine-driven fan. The air is filtered by a rotating disk-like screen mounted over the air inlet before passing through a radiator adjacent the inlet. A duct extends across the face of the disk from its center to periphery, changes direction and terminates with an open end adjacent the inlet side of the fan by-passing the radiator. The duct is also open adjacent the face of the screen so that the fan draws air through the duct, (some of the air being necessarily drawn from inside the screen as it passes the duct opening) so that foreign material filtered from the mass of cooling air being drawn through the unobstructed portion of the screen and held on the screen exterior surface is removed and carried through the duct. A trash knife rigidly attached to the periphery of the screen extends outwards parallel to the screen's axis of rotation.

Abstract: A radiation detector that combines the characteristics of high quantum efficiency in the UV spectrum with good IR transmission characteristics so that it may be used in association with an IR sensor to produce a coaxial transducer suitable for use in association with unfiltered, high-resolution optics. The detector is a solid state photovoltaic Schottky barrier semi-conductor junction comprising a thin platinum layer laid over single-crystal cadmium sulfide. Processing, including lapping, polishing, and chemical etch, produces a surface suitable for providing radiation sensitivity which drops off sharply outside of the ultraviolet spectrum beyond 550 nanometers. The platinum layer is approximately 35 angstroms in thickness and is therefore transparent both to ultraviolet and infrared radiation. The infrared radiation passes through the cadmium sulfide wafer and through a window in the indium ohmic contact surface on the second surface of the cadmium sulfide crystal.
