Abstract: In the production of hollow bodies from oriented thermoplastic material, a cylindrical portion of a heated hollow preform is stretched, with a simultaneous reduction in the wall thickness thereof, at a starting temperature below the vitreous transition temperature of the material. A mandrel is positioned in the preform to support it during stretching, the outside diameter of the mandrel corresponding to the inside diameter of the preform. Directly before the mandrel is inserted into the preform the preform is subjected to re-alignment to adapt at least the cross-sectional shape of the mouth opening of the preform to the cross-section of the mandrel. The re-aligning operation is effected by inserting the preform into a sleeve adjoining a drawing ring for carrying out the stretching operation.

Abstract: A device for the metered dispensation and registration of liquids dispensed from a bottle, comprising a solenoid valve which is attached to the bottle neck, and which is opened and closed magnetically, with the closed position being the rest position of the solenoid valve. The housing of the solenoid valve is provided with coding marks. In addition to the solenoid valve arrangement, the device includes an operating head having a receiving opening for the bottle neck with the solenoid valve, an operating coil for the solenoid valve, a reading facility for the coding marks. A flowmeter which controls the opening time of the operating coil, is positioned downstream of the operating coil. The device further includes a stationary registration facility which is connected to the operating head.

Abstract: In an apparatus for producing hollow bodies from thermoplastic material in large numbers a plurality of stations in which the blanks are successively subjected to various treatment steps are arranged at horizontal spacings around the peripheral surface of a vertical, substantially cylindrical housing of an operating unit of the apparatus. The blanks to be treated are passed downwardly through the operating unit and a first one of the treatment stations therein to the next station therein. Arranged within the operating unit is a cam drum which rotates about a vertical axis and which has cams adapted to actuate tools for treating the blanks in at least some of the treatment stations. Two or more such operating units may be connected in succession for carrying out successive treatment operations on the blanks.

Abstract: An apparatus for treating blanks of plastic material comprising a substantially cylindrical main frame structure, a central, coaxial cam drum which is mounted within same rotatably about its longitudinal axis and which is provided on its outside with working cams, and a plurality of treatment stations arranged in juxtaposed relationship around the periphery of the frame structure, with tools for processing the plastic blanks. The tools in a respective station are carried by vertically movable carriages, each of which is adapted to be moved up and down in the station by a cam follower guided by an associated cam on the cam drum. Each cam follower is carried by a drive carriage. The respectively associated tool carriages and drive carriages are each independently guided on the housing by vertical guide means and are interconnected by way of non-rigid connecting means.

Abstract: In the art of blow molding thermoplastic articles a pair of blow mold halves is closed around a parison. A blowing medium is applied so that the parison is thus blown to a container configuration. In this blowing step very high closing forces are necessary to maintain the mold halves in closed position. The invention provides for a plurality of biased pistons which are actuated by a pressure medium to support the mold halves on a stationary frame.

Abstract: An apparatus to make articles, in particular bottles, from parisons in a blow mold operation. The parisons are carried on transfer mandrels throughout the operation. The parisons riding on the transfer mandrels are heated while travelling around on a first wheel and are transferred into blow mold units mounted on a second wheel. Each blow mold unit is provided with an expanding mandrel which is extended through the transfer mandrel into the parisons. Two different blowing pressures are used in the blowing step which is controlled by cam controlled valves. From the second wheel the mandrels carrying the blown articles are transferred to an output wheel where the articles are removed from the transfer mandrels which are returned to the first wheel.

Abstract: A process is provided for producing a grinding agent carrier comprised of a carrier body and a layer of grinding agent on the surface of the carrier body. The grinding agent layer is initially produced on a planar substrate by sedimentation from a suspension comprised of a suspension medium and grinding agent, and the grinding agent layer is then transferred from the substrate and bonded to the carrier body. The substrate is maintained in a horizontal position and the sedimentation is effected on the horizontal substrate from a liquid column of the suspension wherein the liquid column has a height in millimeters which is at most around 0.4 times the square root of the width in millimeters of the liquid column.

Abstract: Cardioactive glycosides of the formula ##STR1## are disclosed, wherein R.sub.1 is saturated aliphatic hydrocarbon having 1 - 4 carbon atoms or unsaturated aliphatic hydrocarbon having 2 - 4 carbon atoms or phenyl and R.sub.2 is hydrogen or hydroxyl, as are methods for making the same by reacting the corresponding aglycone with an acylated 1-halo-hexopyranose of the formula ##STR2## wherein Hal is halogen, R.sub.3 is hydrogen or alkanoyloxy having 1 - 4 carbon atoms, and R.sub.4 is alkanoyl having 1 - 4 carbon atoms or benzoyl, and subsequently cleaving the acyl groups.

Abstract: Novel cardenolides having desirable cardiac activity and which are readily reabsorbed internally, a process for their preparation and therapeutic compositions containing said cardenolides are disclosed.
