Abstract: DL- .alpha.-phenylglycine can be combined with benzene-sulfonic acid, p-ethylbenzenesulfonic acid or m-xylenesulfonic acid to give the salt. The salt of the racemate may be more soluble in a sulfuric acid solution than the salt of the optically active isomer by suitably choosing the concentration of the sulfuric acid solution, and then the optical resolution by fractional crystallization is carried out. The D- or L- .alpha.-phenylglycine sulfonate is easily liberated of the sulfonic acid portion to give optically active D- or L- .alpha.-phenylglycine.

Abstract: Material is deposited onto and implanted into a substrate by directing a beam of ions against a target, comprised of the material to be deposited, so as to sputter neutral particles and ionized particles from the target towards the substrate. The ionized particles are accelerated to energies sufficient to penetrate the substrate and be implanted therein and provide a strong bond. Sputter cleaning of the substrate surface by particles of sufficient energy also takes place.

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.

Abstract: A support appliance, such as a bed, having an articulated head section is disclosed in which the head section is raisable pneumatically using a bellows and the appliance includes a pneumatic control valve which automatically feeds air to the bellows to compensate for air losses inadvertently occurring in the system and thereby maintains the head section in a predetermined raised attitude.

Abstract: A dual cannula having two adjoining tubes, a leader tube and a follower tube, in staggered arrangement so as to form two separate and distinct passageways for the withdrawal and return of blood to a body. The blood return passageway terminates with a needle aperture and the blood withdrawal passageway has a sheltered aperture. The outer dimensions of the needle portion of the leader tube are substantially the same as the total outer dimensions of the two adjoining tubes for the distance which the cannula is adapted to be inserted into a body, whereby the sheltered aperture is sheltered by the needle portion of the leader tube. Means are provided for shielding the sheltered aperture.

Abstract: A method of coating flexible sleeving is disclosed generally comprising the steps of passing flexible sleeving from a supply source into a heating unit, heating the flexible sleeving in the heating unit to an outside surface temperature sufficient to aid extrudate bonding but insufficient to damage the flexible sleeving, passing the heated flexible sleeving through a crosshead extrusion die assembly wherein the tip and die have substantially zero land length without the application of deformative forces beyond apparatus friction to the flexible sleeving, extruding a coating of an electrically insulative resinous material onto the flexible sleeving in the crosshead extrusion die, cooling the coated flexible sleeving, and processing the cooled, coated flexible sleeving so as to render it thermally stable at all temperature extremes in which use thereof is contemplated.

Abstract: Solar cells are manufactured by a simplified method in which a single protective layer acts as an anti-reflection coating and an encapsulation. In cases where the junction is formed by ion implantation techniques, the same layer also serves as the implantation oxide. In addition, this multi-purpose layer may also serve as a mass analyzer, allowing the desired species of ions to reach the surface of the semiconductor but blocking the heavier undesired species. The necessary contacts may be formed prior to implantation, and the use of alloyed aluminum contacts with aluminum oxide passivation permits a simplified contacting procedure. A fully automatic contacting method and configuration for linear materials is also disclosed.
