Abstract: There is disclosed an environmentally degradable plastic composition comprising an organic polymeric material having dispersed therein at least one amine compound as a readily autoxidizable organic substance.

Abstract: Apparatus for moving newly formed glass containers from a cooling dead plate to a moving machine conveyor in which the ware is engagedf by a finger, with the finger being generally horizontal and engageable with the container at a point on its sidewall which best suits the moving of the container by a sliding motion. The finger, or fingers in the case of plural containers being simultaneously moved, is moved through an arc approximately 90.degree. with respect to its vertical axis, moving the containers from the dead plate to the conveyor and then the finger is retracted out of contact with the containers on the conveyor. The cylinder for extending and retracting the fingers is mounted on the upper end of a vertical shaft, the shaft being oscillated through approximately 90.degree.. In the drive mechanism for the shaft, a sprocket-carrying housing surrounding the shaft is provided with an internally contained, flat spiral spring which connnects the housing to a coaxially positioned sleeve.

Abstract: Disclosed is a digital circuit for generating a swept clock frequency having a linear rate of change. A constant frequency signal is divided by a counter signal representative of the inverse of a linearly changing time dependent variable. The value of the counter signal is varied at the proper rate by means of a pair of rate multipliers and a frequency divider. Included are means for controlling the slope of the output frequency.

Abstract: This invention relates to apparatus and method for producing a composite container having a neck label or tubular sleeve mounted temporarily thereon adapted to be shrunken into final surface covering relation. The tubular sleeve is preformed of relatively-stiff material and flat-folded until ready for use when it is fully opened and conveyed into vertical alignment with a container therebeneath. The sleeve preform comprised of heat-shrinkable plastic material is telescopically assembled onto the container while the latter is transported in spaced upright arrangement. The preform is moved downwardly by a pair of gripping vacuum cups moving downwardly and divergently to open the preform and place the same telescopically on the container upper portion. Alternately, the opened preform is placed on a cylindrical mandrel to more fully open the preform prior to its being mounted telescopically on the container neck portion.

Abstract: There is disclosed an environmentally degradable plastic composition comprising an organic polymeric material having dispersed therein at least one trialkyl ortho ester as a readily autoxidizable organic substance.

Abstract: A fluid collection apparatus is disclosed which is useful in separating blood serum or plasma from blood cellular and particulate matter. The apparatus includes an elongate hollow body having a self-sealing septum sealingly disposed within one end thereof and a piston having an axially projecting hollow piercing element adapted to pierce the septum and provide communication with the interior of the hollow body. The piston includes a laterally extending flange for sealing engagement with the interior of a container for containing the mixture to be treated. After the hollow body and the associated piston assembly is inserted into the container the flange of the piston is engaged with the inner wall of the container causing the composite piston apparatus to remain in and seal a sample within the container.

Abstract: There is disclosed an environmentally degradable plastic composition comprising an organic polymeric material having dispersed therein at least one unsaturated wax as a readily autoxidizable organic substance.

Abstract: An improved shell mold and method are provided for thermal conditioning a thermoplastic parison prior to blow molding the parison into a hollow container and especially a biaxially oriented container. The mold has an inner shell and an outer shell defining a passageway therebetween for a circulated heat transfer fluid. Heat transfer between the fluid and the parison is controlled to adjust the thermal history at different locations of the parison as it will be required by the mode of stretching and the blow out ratio at the different locations.

Abstract: A circuit for generating a square wave form which circuit comprises two MOSFETs and is driven by only one control logic signal. A first MOSFET is connected between a ground potential power supply and the circuit output line while a second MOSFET is connected between the circuit output line and a positive potential power supply. The gate of the second MOSFET is connected to the source of the first MOSFET which has a gate connected to receive the control logic signal. When the logic signal is at a high level, the first MOSFET is turned on and the gate of the second MOSFET is pulled down to ground potential such that the second MOSFET is turned off. Thus, the circuit output line will be near the ground potential. When the logic signal switches to a low level, the first MOSFET is turned off and the voltage across a capacitor which has been charged by a power supply causes the second MOSFET to turn on such that the circuit output line will be near the positive potential.

Abstract: A fabricated cup or nestable container having a unitary sidewall formed from a double-ended sheet of a heat-shrinkable thermoplastic material, the inner suface of which is adapted to contact a liquid product to be contained in said container. The ends of the sheet are joined to one another forming a liquid-tight seam extending from the top to the bottom of said container. An open mouth at the top is defined by the upper portion of the sidewall. The container sidewall tapers inwardly and downwardly from the open mouth for a major portion of the height of said container. The thickness of the sidewall increases continuously and progressively over this major portion from a lesser thickness at the top thereof to a greater thickness at the bottom thereof. The density of the sidewall continuously and progressively decreases over this major portion from a greater density at the top thereof to a lesser density at the bottom thereof.

Abstract: Disclosed are new copolyesters of terephthalic acid, bis(4-.beta.-hydroxyethoxyphenyl)sulfone, ethylene glycol and a very small amount of trimellitic acid, particularly useful as molding compounds, especially for the extrusion-blow molding process of making hollow articles, and a method of making hollow articles.

Abstract: Disclosed is a luminescent solar collector comprising a relatively thick layer with a photocell coupled to a face surface thereof and at least one thin luminescent layer optically coupled to said thick layer, said thick layer having an index of refraction at least 0.04 more than each of said luminescent layers and being at least 10 times as thick as the sum of all other layers of said collector.

Abstract: Disclosed is a luminescent solar collector optically coupled to a photovoltaic cell and in confronting relationship thereto a diffusing layer of a particulate phosphorescent material deposited on and backed by a mirror.
