Abstract: A coextruded tri-layered medical-surgical tubing for the administration of common medicines such as insulin and nitroglycerin solutions is disclosed. Improved flexibility and uniformity and increased peel strength are obtained by interposing a layer of an ethylene-vinyl acetate copolymer between an outer layer of polyvinyl chloride and a core layer of low-density polyethylene. The composite tubing exhibits excellent fluid flow characteristics and is readily employed in the transportation of intravenous fluids and the like without absorbtion or contamination difficulties.

Abstract: An improved procedure is disclosed for the electrostatic precipitation of particulates entrained in a stream of gas between corona electrodes and collecting electrodes. The underlying dc field which serves to charge the particulates and transport them out of the stream is relatively uniform and therefore can be relatively high, while the corona which is required to yield ions to charge the entrained particulates is provided by a high repetitively pulsed electric field between the corona electrodes and the collecting electrodes. Embodiments are presented which suggest the manner in which conventional precipitators may be adapted to the present invention.

Abstract: An improved procedure is disclosed for supplying the power to an electrostatic precipitation system of the type wherein an underlying dc field serves to charge the particulates and transport them out of the stream of gas, while the corona which is required to yield ions to charge the entrained particulates is provided by a high, repetitively pulsed, electric field between the corona electrodes and collecting electrodes. The present disclosure reduces overall power input by connecting the corona electrodes in series and applying very narrow, frequent and high-amplitude pulses to one end of the series-connected cathode wire structure so that the pulses are propagated along the structure, thereby pulse-charging only a small portion of the precipitator at any given instant of time.

Abstract: A contact lens comprising a silicone polymer or copolymer core and a hydrophilic polymer surface grafted to the core is formed by contacting a silicone with a free radical polymerizable precursor to the polymer in a liquid state and subjecting the precursor and silicone to a high dose of ionizing radiation for a short period. The radiation dose, time of radiation and temperature are controlled to produce an optically clear contact lens by forming a smooth surface of the polymer grafted to the silicone, preventing substantial migration of the precursor into the silicone and preventing localized high concentration of hydrophilic polymer on the silicone surface.
