Abstract: The present invention relates to a process for preparing highly digestible feed that may be used among others as feed for aquaculture, by a yeast treatment characterized in that yeast cells are processed to hydrolyze at least partially the external layer of the cell wall without damaging the wall itself.

Abstract: Processes and apparatus are disclosed for the catalytic purification of styrene monomer by hydrogenating the phenylacetylene contaminant therein to styrene in a catalytic bed using multiple hydrogen injection; dilution of the hydrogen by a diluent such as nitrogen; mixing the hydrogen with a catalyst-selectivity improver such as carbon monoxide; using ethylbenzene dehydrogenation ventgas to supply hydrogen; and, using a multiple-catalyst-bed-reactor, or multiple reactors, each with a single catalyst bed. One preferred phenylacetylene reduction catalyst used is palladium on an alumina carrier.

Abstract: The present invention discloses a vacuum-assisted vapor recovery system for loading vessels with volatile materials such as liquid hydrocarbons, including gasoline and distillates, which system utilizes a series of interlock premissives and vacuum controllers to maintain a vacuum on the vapor header of the vessel being loaded, which vacuum is within a desired, predetermined level. The system is further arranged and adapted to shutdown the filling of liquids into the vessel should a vacuum leak be detected or should any other malfunction of the vapor recovery system or the liquid filling system arise.

Abstract: A spent absorbent material comprising a supported mixture of nickel oxide and metallic nickel may be reactivated a limited number of times by heating the material at 150.degree.-450.degree. C. under a flow of non-oxidizing gas.

Abstract: Transparent linear resinous conjugated diene/monovinyl-substituted aromatic block copolymers of improved properties are prepared by forming a monovinyl-substituted aromatic homopolymer block referred to as S.sub.1, followed by forming a conjugated diene homopolymer block, referred to as B.sub.1 and linked to segments S.sub.1, followed by the formation of a conjugated diene/monovinyl-substituted aromatic random copolymer block, referred to as B/S and linked to segment B.sub.1, followed by the formation of a monovinyl-substituted aromatic homopolymer block, referred to as S.sub.2 and linked to segment B/S thereby forming the block copolymer S.sub.1 -B.sub.1 -B/S-S.sub.2 wherein the molecular weight of the S.sub.2 block is significantly greater than the molecular weight of the S.sub.1 block.

Abstract: A process is disclosed for producing ethylbenzene from the catalytic alkylation of benzene in a multibed reactor wherein a portion of the normal overhead polyethylbenzene recycle stream is diverted into a lower section of the reactor to increase conversion and lower xylene by-product production.

Abstract: Shop primer compositions having improved properties comprise (a) fillers and pigments, at least 25 wt. % of which have conductive properties; (b) zinc powder in a weight ratio to fillers and pigments between 1:16 and 1:1; wherein the zinc, fillers and pigments are milled to a sufficient fineness; (c) anti-settling agents; (d) optionally, thickening agents; (e) a silicate-type binder, in an amount such that the weight ratio of the SiO.sub.2 content of the binder to the zinc, fillers and pigments is between 1:4 and 1:16; and (f) solvents.When using the shop primer compositions of the present invention, the welding properties are improved and the health hazards during welding are reduced, without having to remove the primer layer at the welding area. The primer coatings are compatible with the welding techniques generally used in the heavy steel construction industry, including MIG/MAG welding in 3F position.

Abstract: A continuous process for the production of high impact polystyrene using a free radical initiator which decomposes to form only non-acid decomposition by-products.

Abstract: A continuous flow process for the production of high impact polystyrene, wherein specific types of polymerization inhibiting impurities are removed from a recycle stream prior to feeding or introducing the recycle stream into a styrene polymerization zone. Preferably, the process further comprises the step of monitoring the acidity of the recycle stream.

Abstract: A quick-connection type connector is disclosed for the coupling of high-pressure fluid flow lines, which connector utilizes an externally threaded female portion and a tapered male portion with a rotatable collar mounted thereon. Elastomeric seal means are provided as well as a metal-to-metal seal to protect the elastomeric seal means, and a locking assembly to prevent backing off of the threaded portion.

Abstract: Process and apparatus are disclosed for manufacturing foamed articles such as tubes used as pipe insulation, which tubes are of a high impermeability and flexibility and are formed of a polymer, such as polyethylene or polypropylene, containing up to as much as 50% of an elastomer.

Abstract: The apparatus for making plastic containers having decreased gas permeability includes a chamber, an ionizing source located in the chamber for ionizing a material to be deposited on the containers, and a screen located between the ionizing source and the containers for preventing damage to the containers by heat generated by the ionizing source. The method includes the step of locating a screen between the ionization source and the container whereby heat generated by the ionization source will not damage the container.

Abstract: A process for forming hollow articles from a thermoplastic polymer sheet material. Polymer sheet material is heated to a forming temperature and clamp between a ported mold plug and a jacketed mold cavity. The mold plug is moved into the mold cavity to stretch the material into the cavity. The clamping is released during the moving of the plug and a substantial portion of the air trapped between the material and mold cavity is evacuated. Pressurized forming gas is injected through flow means around the mold plug to further expand the material into the mold cavity. Thereafter, the injecting of forming gas is discontinued and coolant is flowed through the jacketed mold cavity and a cooling fluid is injected through the ported mold plug against the material while the pressurized forming gas is simultaneously purged from the area between the mold plug and expanded material through the flow means.
