Pre-filled glass-plastic syringe with ejectable plug - suitable for prolonged storage of contents prior to use

Syringe is suitable liq. prods., e.g. medicaments. It comprises a cylindrical glass tube, a plastic handle fixed at one end a plastic tubular tin fixed at the other. A sliding piston, with a control rod, is fitted at one end, with an ejectable closing plug at the other; the liq. is contd. in the glass tube between the piston and the plug which is made of rubber; when the syringe is used, the forward displacement of the piston and the liq. pushes the plug into a forward chamber which has a larger internal dia. than the plug. The liq. can, therefore, flow around the plug into the nozzle. The new syringe combines the advantages of glass and plastic material. The glass tubes can be handled mechanically before and after the hendle and the nozzle have been pushed into position.

Glass tube and thermoplastic resin finger-grip and nose sleeve syringe body assembly

A glass tube and thermoplastic resin finger-grip and nose-forming sleeve syringe body assembly in which, the finger-grip sleeve and the nose-forming sleeve are each cam-stretched onto and frictionally retained on respective opposite ends of a glass tube, which is a section of die-formed glass tubing. Increase in latitude of operable interference fit and stretch is effected by assembling the finger-grip and nose-forming sleeves onto the glass tube while the sleeves are in a heated condition.

Solid lubricant and composition

A solid lubricant and composition useful for lubricating the flanges of locomotive wheels, railcar wheels, rail track and in applications where it is desirable to reduce friction when metal contacts metal. The solid lubricant having from about twenty-five percent to about seventy percent by volume of a polymeric carrier, about five to seventy-five percent by volume of organic and inorganic extreme pressure additives, about zero to twenty percent by volume synthetic extreme pressure anti-wear liquid oil, and about zero to one percent by volume optical brightener.

Injection needle assembly - with bandage acting as a handle and as a cover for the injection puncture

Needle assembly for releasably fixing to a part of the body, comprising an assembly of a needle with a pointed end and a flexible bandage with a flexible fixing film having a pressure-sensitive adhesive surface capable of adhesion to the surface of the skin pierced by the needle, so arranged that the needle can be fixed to the flexible bandage-fixing film which together with the bandage can be folded along a longitudinally extending zone to form a folded flap-type handle for the needle. This makes it possible for the needle to be mounted in the patient without direct contact of the user with the needle, with a bandage not only serving as a handle but also being able to fix the needle in place and cover the position of the puncture.

Lubricant compositions

Lubricant composition formulations comprising at least one biodegradable plastic, such as polyhydroxyalkanoate and/or polybutylene succinate, and at least one lubricant, such as a vegetable oil.

SYRINGE ARRANGEMENT MADE OF PLASTIC AND GLASS WITH EXPRESSIBLE ELASTIC PLUG SEAL

Syringe assembly with contained pop-out elastic plug seal

A prefillable or prefilled syringe having a liquid-containment glass tube body section with thermoplastic resin finger-grip sleeve and noseforming sleeve fit thereon in an interference fit, and with the ends of the glass tube being sealed after filling and preferably prior to assembly of one or both the finger-grip sleeve and the nose-forming sleeve, and a method of assembly thereof, the finger-grip sleeve and the nose-forming sleeve being cam-stretched onto and frictionally retained on and along a glass tube, in the form of a section of die-formed glass tubing. Increase in latitude of operable interference fit and stretch is effected by assembling the finger-grip sleeve and the noseforming sleeve in a heated condition, without requiring heating of the glass tube and its prefilled contents. A preferred embodiment utilizes a pop-out valve plug seal in the nose end of the glass tube, with a plunger piston at the opposite end, for sealed prefilled containment of a liquid drug or other chemical agent in the glass tube.

Biodegradable plastic based lubricant compositions

ABSTRACT OF THE DISCLOSURE Biodegradable lubricant composition formulations comprising at least one biodegradable plastic, such as polyhydroxyalkanoate and/or polybutylene succinate, and at least one lubricant, comprising a biodegradable oil, such as a vegetable oil, and a solid lubricant. The lubricant composition may be formed into a dosing stick which may be used to lubricate the wheel of a rail vehicle to reduce rail and wheel contact friction.

Patent FR2208685B1

Medical syringe with plastics finger grips - fitted on polypropylene sleeve over end of glass tube

Glass tube with finger grip from plastic material, esp. for packing and dispensing chemicals, including sleeve from polypropylene tightly fitted over the end of the glass tube. One end of the sleeve is provided with two outwardly projecting opposite, flanges for holding and handling the tube and the other end of the sleeve has its leading ring shaped surface chamfered toward the sleeve bore to facilitate easy insertion of the glass tube. The leading end of the tube is either chamfered at an angle to its axis or the chamber forms part of the widened and rounded end of the tube. The sleeve has, inside its bore, projecting ring shaped shoulder positioned opposite the outwards projecting flanges against which the end of the inserted glass tube is located.

Automatic filling machine-valve assembly

A valving mechanism for an automatic filling machine for transferring liquid pre-measured doses to receptacles such as oral dispensers, nebulizer injectors, vials and hypodermic syringes. The automatic filling machine includes a piston type pump which is connected to a supply reservoir for the liquid and to an individual receptacle to be filled by flexible, compressible tubing. Alternately energized alternating current solenoids reciprocate a pivotally mounted lever which alternately closes one of the flexible tubes and opens the other to permit the piston pump to draw liquid from the reservoir and pump it to the receptacle. The valving mechanism includes two adjustable screws, one for each flexible tubing, to pre-compress each tube. Over-compression of the tubes is precluded by an audible warning afforded by the solenoids themselves.
