Date Jan. 24, 1991.A disposable hypodermic syringe is disclosed having a barrel (4), a hub (1) and needle holder (2) locatable on the barrel, a plunger (5) with a piston (13) at one end thereof slideable within the barrel, and an interlockable structure on the plunger and needle holder for interlocking the same one relative to the other so that after use the needle (3) is fully retractable into the syringe barrel (4) to prevent accidental stabbing and risk of infection. The needle holder tube (2) has internal barbs (10) which engage behind a domed head (8) of the plunger (5). During use (suction and injection delivery) the plunger domed head (8) is retained behind a membrane (14) within the piston (13) by similar internal barbs (20) inside the piston (13). Preferably the interconnection between the needle holder (2) and hub (1) is a screw thread and the plunger is rotatable to detach the needle holder (2) and needle from the hub. In one alternative form the needle (3) is supported in the needle holder (2) by a weakened structure breakable by axially applied pressure upon the piston rod (5). The weakened structure (44) is generally of a thinner molded thickness than the remaining molding and is further weakened by Gamma Irradiation or other electron beam.

    • 212,297. Redmayne, L., (Williams, F. H., and Weatherall, M. E.). Dec. 4, 1922. Solid supply to liquid.-An acetylene generator of the carbide-to-water type for use with lamps, &c. and in which the carbide supply is controlled by a valve p suspended from the gas-holder e, the latter is arranged to be kept in its raised position when the lamp is not in use, by means of a nut k mounted on the outlet pipe h and which can be screwed down on to the cover b of the water vessel a. The carbide-container g is supported from the base of the generator by standards f secured at their lower ends to a ring f ; to this ring is secured an outer set of standards f terminating in their upper part in a ring f from which a. short cylinder c is supported; the cylinder prevents a. large accumulation of gas due to escape from the lower edge of the holder. The carbide-feed valve p which may be of the differential type, is positioned centrally in the lower part of the carbide-holder and is suspended by means of a rod o from a perforated plate or collar k in the outlet pipe ; a stirrer for agitating the carbide may be mounted above the valve.
