Abstract: ABSTRACT OF THE DISCLOSURE      A reverse switching rectifier is described in which a PNPN semiconductor structure has a specially adapted N-type end zone or cathode-emitter zone. The N-type end zone penetrates to two different levels in the semiconductor body. A deep central portion and a shallow peripheral portion of the N-type end zone are produced by etching a cavity in the center of the body followed by diffusion of N-type dopant material. The exposed surfaces of the N-type end zone are then metallized to provide electrical and thermal contact thereto.

Abstract: SELECTIVE TIN DEPOSITION ONTO ALUMINUM PISTON SKIRT AREAS         ABSTRACT OF THE DISCLOSURE     A cost saving method for protecting an engine element against operation galling and corrosion is disclosed. The element, particularly a piston, is cast of aluminum and cleaned free of dirt and organic matter.  A warm stream of an aqueous solution containing a protective metal agent is directed onto a selected zone of the element.  The agent consists essentially of potassium stannate and the zone is preferably the middle region of a piston skirt extending from the upper skirt periphery to lower skirt extremity (tail).          The stream is maintained as a laminar flow as it traverses the selected zone.  An ultra-thin protective coating is adherently deposited on the zone of the piston.

A vehicle of the aforesaid kind has a body which is open at the back and comprises spaced side walls and a front wall and a vertically movable floor is arranged therein and is progressively lowered as successive layers of articles are formed within the upper part of the body.      The said barrier member may have the form of a rail or bar or it may be an auxiliary wall which preferably is shallow in depth so as to be disposed wholly above the level of the floor when the latter is in its uppermost operative position whereby it is movable inwardly above the latter.      The said barrier member or one or more of them, is preferably movable inwardly by power actuated means, thereby to push the bales or other articles closer together.      More particularly each of the barrier members is disposed inwardly of, and adjacent and parallel to, a corresponding side or end wall of the body which nay also be open at the bottom so that the floor may be lowered onto the ground and then detached from its raising and lowering means.      The floor may also support a longitudinally slidable pallet or false floor so that the latter may be discharged together with a stack of bales formed thereon.

Abstract: LUBRICATING SYSTEM AND METHOD   FOR TURBOCHARGED ENGINES     A B S T R A C T      An engine comprises a pump adapted to communicate lubricating oil from the crank case thereof to a directional control valve.  Upon engine start-up, the valve is con-ditioned to communicate oil through a filter and to a first manifold which, in turn, communicates with the crankshaft and rod bearings of the engine.  Simultaneously therewith, cooled but unfiltered oil is communicated directly to bearings rotatably mounting a shaft in a turbocharger, mounted on the engine.  After start-up, the valve will shift to further communicate unfiltered oil directly to a second manifold which, in turn, communicates with a plurality of Jets for the purpose of cooling the pistons employed in the engine.  The shifted valve will further function to permit communication of oil through the filter to the bearings of the turbocharger and to the crankshaft and rod bearings of the engine.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to deuterium isotope separation and enrichment and more particularly to deuter-ium isotope separation and enrichment using infrared laser technology in combination with chemical processes.  Deuter-ium occurs in nature to the extent of about 0.014%.  Pre-sently, multi-stage equilibrium partition methods are employed to concentrate the naturally occurring deuterium. Such methods involve bulky equipment and large materials handling problems because of low enrichment factors per stage.  Therefore, there is low throughput and long time periods involved in order to attain steady state equili-brium conditions.  A present invention provides a method of separating deuterium from certain naturally occurring sources using tuned infrared lasers to selectively decom-pose specified classes of organic molecules (i.e. RX) into enriched molecular products containing deuterium atoms.  The deuterium containing molecules are easily separated from the starting material by absorption, dis-tillation or other simple chemical separation techniques and methods.  After evaporation such deuterium containing molecules can be burned to form water with an enriched deuterium content or pyrolyzed to form hydrogen gas with an enriched deuterium content.  The undecomposed molecules and the other reaction products which are depleted of their deuterium containing species can be catalytically treated, preferably using normal water, to restore the natural abundance of deuterium and such restored molecules can then be recycled.

Abstract: ABSTRACT OF THE DISCLOSURE         Compositions consisting essentially of a (i) resin mixture containing a low molecular weight polyvinyl alcohol and a medium molecular weight polyvinyl alcohol, and optionally, a copolymer of vinyl alcohol and an ethylenically unsaturated ester and (ii) as a plasti-cizer a polyethylene glycol, which compositions can be used for preparing films by melt extrusion or aqueous casting. These films are suitable for use as packaging film in automatic packaging equipment.  They can be used to package pulverulent materials, and the film package containing the pulverulent material can be charged directly to water in which the film will dissolve, thus eliminating the problem of user contact and exact measuring of the package contents, as well as disposal of containers in which the pulverulent materials would otherwise be packaged.  Moreover, these films provide enhanced resistance to breakage of packages made therefrom when such packages are handled or shipped, even under cold or dry conditions.

Abstract: ABSTRACT OF THE DISCLOSURE:                Styrene polymers or copolymers containing bromine are manufactured by cationic polymerization of the monomer, or of the monomer plus a copolymerizable monomer of the isobutylene or nuclear-alkylated styrene type, in an organic solvent is the presence of a Lewis acid catalyst to a mean molecular weight (number average) of from 800 to 8,000 for the polymerization product.  Bromine is then added to the solution without first working up to the latter.  The catalyst used for the bromination is the same as that used for the polymerization.  If necessary, fresh catalyst may be added before the bromination.  After completion of the bromination, the reaction solution is extracted with water until it is bromide-free, and the solvent, generally a halohydrocarbon, is then stripped off. Products containing up to about 80% by weight of bromine may be obtained.  They have a pale yellowish color and exhibit no significant decomposition up to 340°C.  They may be used as flame-proofing agents for thermoplastics.
