Abstract: Abstract of Disclosure:            A blood extraction device has a cylindrical extraction tube with a piston movable in an air-tight manner within the tube. A closure cap carries a projection at the front end of the tube and a tubular guide sleeve which can be pushed onto the extraction tube.  At its front end, the guide sleeve carries a double cannula having front and rear ends provided with respective cutting edges.  A closure plug, puncturable by the rear end of the double-ended cannula, is arranged in the projection.  In operation the front end of the cannula is inserted into a vein and the guide sleeve is moved onto the projection so that the rear end of the cannula punctures first of all a thin hose and then the closure plug.  One or more retaining lugs provided on the side wall of the projec-tion cooperate with one or more axial slots provided in the guide sleeve to prevent rotation of the rear cutting edge of the cannula relative to the rubber hose and the closure plug as it moves through these components which could otherwise destroy the self-sealing properties of these components that are required on removal of the cannula.  After the cannula has penetrated the closure plug, the guide sleeve can be rotated relative to the projection so that the retaining lug or lugs enter into lateral recesses at the front ends of the slots thus preventing axial separation of the guide sleeve and the extraction tube.  In this position the resilience of the rubber hose acts to secure the twist actuated locking mechanism formed by the retaining lugs and the recesses at the ends of the axial slots.

Abstract: ABSTRACT OF THE DISCLOSURE           A rotary compressor of the sliding vane type in which the refrigerating capacity at high speed opera-tion of the compressor is restrained by making use of the drop of the refrigerant pressure in the vane chamber down to a level below the pressure of the refrigerant supply source in the suction stroke of the compressor.  The com-pressor has a rotor, vanes slidably carried by the rotor, a cylinder accommodating the rotor and the vane, plates fixed to the cylinder and closing opposite open ends of vane chambers defined by the rotor, the vanes and the cy-linder, and a suction port and a discharge port which pro-vide passages between the vane chambers and the outside of the compressor.  A spacer for adjustment of the re-frigerating capacity is disposed in the suction port.  When the compressor is used in an automobile air conditioner, it is possible to obtain a desired refrigerating capacity controlling characteristics of the compressor matching the characteristics of the engine and automobile, simply by selection of the spacer without substantially changing other parts of the compressor.

Abstract: AN OVERLOAD COUPLING OR CLUTCH                 ABSTRACT OF THE DISCLOSURE          An overload clutch or coupling includes a hub section connected to one drive element and a housing connected to another drive element.  Plungers are fitted in sockets in the housing such that the shank portions of the plungers project from one side of the housing and conical end faces project from the other side of the housing where they engage with plunger seats on the hub.  The hub has pull pin sockets that receive spring-biased pull pins and apply a force to a pressure plate that acts on the projecting shank portions of the plungers to maintain them in the plunger seats.  The plungers are displaced from the seats when the torque between the hub and housing exceeds the maximum torque to be transmitted by the coupling or clutch.  The housing can slide along the plungers to accommodate floating movement between the driven and driving parts of the clutch or coupling.          A keeper plate is attached to the hub to retain the housing against such floating axial movement when desired.  A pinion gear carried by a clamp ring attached to the hub meshes with a hub gear for index positioning.

Abstract: Abstract Superabsorbent gel compositions useful as plant growing media additives are prepared from a copolymer of acrylamide and acrylic acid salt in a molar ratio of 70:30 to 95:5, cross-linked such that less than 30% by weight of the dry polymer is water-soluble and the gel can absorb releasably at least 15 times its own weight of water.  The gel composition is therefore tailored to the needs of an agricultural/horticultural context because it has long-term stability in natural soil, low solubility that would otherwise lead to poor soil properties, and good water absorbency.  Preferred gel compositions in foam form are described.
