Abstract: A pulper to convert bulky, solid wastes from food service establishments into a uniform, moist pulp. The material is pulverized in a first section and transferred as a slurry to a second section where the slurry is dewatered by an auger. To prevent clogging of the auger, a portion of the liquor extracted from the pulp is introduced as a jet stream into the upstream end of the auger to create turbulence. Additionally, a reverse flow of water through a drain chamber in excess of the amount of water required for make-up in the system is employed to prevent clogging of the screen covering the drain.

Abstract: A conveyor has successive mutually spaced driven rollers in which hot rolled steel rod is transported in the form of overlapping offset rings. The rings are rapidly air cooled by first nozzles which direct first jets of cooling air upwardly to impinge against and to flow around the conveyor rollers, and by second nozzles which direct second jets of cooling air upwardly between the rollers. The first and and second jets of cooling air produce respective first and second velocity profiles, each having an average velocity. The arrangement of the first and second nozzles in relation to each other and to the conveyor rollers is such that the velocity profiles of the first and second jets are superimposed one over the other to produce a broader combined velocity profile having an average velocity greater than that of either the first or second velocity profiles.

Abstract: A pressure relief device for an internally pressurized container. The device is imperforate, forms an integral part of the container surface, and has a concave annular outer area integrally joined to an inwardly protruding circular central area by an annular intermediate area. These areas have different thicknesses resulting exclusively from the device having been drawn from a metal blank. The juncture of the annular outer and intermediate areas forms a first circular line of strain hardened material having a reduced thickness and increased hardness and strength as compared to the material thickness, hardness and strength of the annular outer area. The cross sectional configuration of the device is such that upon eversion thereof occasioned by an over-pressurization of the container contents, the material along the first circular line will fracture at at least one location, thereby allowing the container contents to escape therethrough.

Abstract: A rolling mill roll stand has a housing removably mounted on a lower bridge. A pair of work rolls and their respective bearings and bearing chocks are contained within the housing. Separating devices act on the bearing chocks to maintain a gap between the work rolls. Hydraulic roll positioning cylinders are carried in the lower bridge and are arranged to act on the bearing chocks of one of the work rolls. The housing together with the work rolls, bearing chocks and separating devices is removable as a unit from the lower bridge, while allowing the hydraulic positioning cylinders to remain undisturbed.

Abstract: Sulfur oxides are removed from a flue gas stream with an upflow quench reactor, a dry venturi and a baghouse. The lime slurry used in the quench reactor is doped which enhances the neutralization reaction in the dry venturi and the bag filter. The use of the dry venturi allows a substantial buildup of solids on the filter wherein the baghouse functions as a fixed bed reactor.

Abstract: A method for rolling and heat treating small diameter stainless steel rod, comprising the following sequence of steps: cooling the rod prior to and during finish rolling to increase its stiffness; passing the rod through a sizing mill to achieve close tolerances; subjecting the rod to additional water cooling to thereby improve its resistance to surface scratching; forming the rod into rings which are received in an offset pattern on an open moving conveyor; subjecting the offset rings moving along the conveyor to a solid solutioning treatment by reheating and water quenching the same; and then air cooling and drying the rings before collecting them into coils.

Abstract: A soil bed is spaced apart from a lagoon of saline water. The liquid vapor in equilibrium with the saline water permeates into the soilbed via diffuser tubes. At dusk the temperature of the soilbed decreases. The liquid vapor is entrapped in the soilbed and condenses. Additionally solar stills embodying flumes generate liquid vapor which is transported to the soilbed.

Abstract: An easily cultured worm is genetically modified such that its surface antigens on its modified form are immunologically identical to the surface antigens of a parasitic worm. Specifically, C. elegans is genetically modified to produce antigens corresponding to the antigens of D. immitis which causes heartworm infection. The antigens derived from the easily cultured worm are used to form a vaccine and/or diagnostic.

Abstract: A continuous tubular film passes through two opposed vacuum plates. One of the vacuum plates has a heated die formed therein. The film is pillowed and a portion contacts the die. A section is cut from the film and removed and, subsequently, the pillowed film is deflated. These steps are repeated in timed sequence. The apparatus and process allows the forming of apertures or sections in one side of a tubular film alone.

Abstract: An accommodating linkage device which operates in three modes to provide, upon command, either: (1) a standard, resetable, rigid linkage between two objects; (2) a flexible linkage which responds to relative motion (forces) between two objects; (3) or an arbitrary, rigid linkage between two objects. The device includes two ball joints which connect to the two objects, a pair of locking pistons, and a pair of alignment pistons. Operation of the device is in response to either control signals or to forces generated by the relative motion of the two objects, depending upon operating mode.

Abstract: An oxygen analyzer which measures the level of dissolved oxygen in a liquid stream. The measuring process embodies chronoamperoemetry of pulsed potential voltammetry. The signal from the electrode is real time averaged. The analyzer does not require temperature, salinity or pressure compensation circuitry and does not have to be calibrated repeatedly.

Abstract: Standard casing ends are formed for horizontally or vertically split casings. The casing end includes a variable dimensioned extension which is adapted to abut a shell section. The casing also includes a variable dimensioned stub end adapted to abut a nozzle. Once a shell thickness is determined, the extension is trimmed back to match the thickness of the shell section. The stub end is trimmed back and its inner diameter is enlarged, if necessary, to match the dimensions of a selected nozzle.

Abstract: This invention relates to a quick release clamp for applying the laterally constrictable ears of a cable connector to the terminal of an electric storage battery. The clamp includes a bolt having a threaded shank terminating at one end in an enlarged head. The shank is dimensioned to extend through aligned holes in the connector ears, with the bolt head being located on the outermost side of one of the ears. A nut is threaded onto the bolt shank on the outermost side of the other of the connector ears. A cam lever is rotatably connected to the bolt, and is adjustable between a closed position cooperating with the bolt and nut to laterally urge the connector ears together to grip the battery terminal therebetween, and an open position permitting the connector ears to move away from each other to an extent sufficient to permit the cable connector to be removed from the terminal.

Abstract: A single strand rolling mill has successive pairs of work rolls arranged to roll rod and bar products in a twist-free manner. The work rolls are carried on roll shafts included as part of roll packages which are detachably mounted to gear housings, and the gear housings contain intermediate drive shafts and intermeshed gears connected via line shaft segments and intermeshed bevel gears to a primary mill drive. The gear housings are carried on a base which is made up of a flat vertically upstanding structural member standing on edge and joined to an underlying base plate. The structural member extends beneath and in parallel relationship to the rolling line. Rib members extend laterally away from and are spaced along opposite sides of the structural member. The rib members are joined on edge to both the structural member and the base plate and have upper support edges on which the gear housings are secured.

Abstract: A process for controlling the development of somatic embryos for either a self-replicative or a vine development mode. Somatic embryogenesis is initiated by placing the embryo in a medium conducive for self-replication. When the embryos have grown to a first stage, they are transferred to a medium with cytokinin activity. They continue to grow until they have grown to a second stage at which time they are transferred to a medium without cytokinin activity until they have grown sufficiently and can be transferred to a non-liquid growth medium.
