Abstract: A prefabricated medical implant made of polymeric material having increased wear resistance without substantially changing its ductility and other physical properties is described. The implant is formed by a method including the steps of heating a sealed, packaged, prefabricated implant, having a reduced oxygen atmosphere, to an elevated temperature below its annealing point at a predetermined rate and held at that temperature for a predetermined time. After this time the packaged implant, while being maintained in a predetermined temperature range, is irradiated with a predetermined amount of gamma radiation. After irradiation, the implant is permitted to cool at a predetermined rate. Thermal conductive and thermal insulation containers are also provided for holding the packaged implants during the process.

Abstract: A fluid conveyor jet moves flexible containers or bags along a trough from one station to the next in the trough in a process which efficiently heats or cools the contents of the containers. Side fluid jets positioned along opposite sides of the trough direct heating or cooling fluid (water) on the flexible containers at the stations. They direct the fluid generally in spaced horizontal planes on the flexible containers therebetween causing (1) the central contents of the containers to move away from central areas of the container towards the sides to promote temperature transfer between the contents and cooling or heating fluid from the fluid jet conveyor and the fluid jets and (2) the containers to rotate generally about axes parallel to a longitudinal axis of the trough also helping in the cooling or heating process. The side fluid jets are operatively positioned below the waterline of the trough.

Abstract: Microorganisms are destroyed and enzymes can be inactivated in liquids, such as juices for example, by continuously flowing the liquid and continuously flowing pressurized dense CO2 along flow paths which are separated by membrane having minute pores at which the flows contact each other in a nondispersive manner. Pressures in the two flow paths are equalized and the dense CO2 flow is continuously recirculated without depressurization. Contact between the flows can be maximized by using a plurality of parallel hollow fiber porous membranes with one of the flows being directed into the hollow fibers and the other of the flows being directed along exterior surfaces of the fibers. The process does not adversely affect properties of the liquid, such as taste, aroma and nutritional content, as heating of the liquid to a high temperature is unnecessary.

Abstract: A method and a machine for preparing and filling containers with a product, for which method and machine the containers are grouped in rows at right angles to the transporting direction with the container openings facing upwardly and aligned at a distance from one another. The containers are swiveled, row by row, into an at least approximately vertical position with the container openings facing downwardly and rinsed jointly on the inside with a cleansing agent. The rinsed containers are dried on the inside in a first drying station and, after passing through the first drying station, are charged into a sterile environment. After a row of containers has entered the sterile environment, the containers are sterilized on the inside by means of a sterilizing agent and, in a second drying station, residues of sterilizing agent are expelled from the sterilized containers.

The process of making an air freshener includes forming the salt material into a sculpted shape, selecting and coating the formed salt material with a coating material having bactericidal properties, mounting the coated salt material to a base having a heater therein, and heating the salt material to reduce airborne microbiological agents adjacent thereto and to freshen the air therearound.

Abstract: A method of and system for sterilizing the internal surfaces of one or more elongate relatively narrow passages of interest contained in a device of interest, said passages having end openings and being susceptible of sustaining flow there along by inducing a positive flow of sterilizing gas through each passage of interest in a selected direction. Gas flow through a device of interest is caused by a passive two-chamber device which generates a transient pressure gradient between the ends of the lumens of the device in response to externally imposed variations of pressure. Sterilant gas is provided from outside the two chamber systems.

Abstract: The invention provides an apparatus and method for storing and transporting peritoneal dialysate in dry or lyophilized form, and for forming a deliverable peritoneal dialysis solution therefrom. In one embodiment, a dry reagent bed, including reagents sufficient to produce a dialysis solution, is suspended in a diluent flow path through the apparatus housing. Continuous pressure on the reagent bed causes the bed to compact as it erodes when purified water is passed through the housing. The pressure ensures complete and even dissolution of the reagents. Through dry storage and simple dissolution, even in a home, the invention enables a wider variety of solution constituents, including reduced acid content and the use of bicarbonate as a stable buffer component. The latter is illustrated in a double-bed embodiment, where bicarbonate is stored separately from calcium or magnesium salts within a single housing.

Abstract: A method for processing two or more oilseeds includes the steps of providing a first oilseed type and a second oilseed type, processing the first oilseed type to extract a first oilseed product from the first oilseed type, creating a gap in the flow of the first oilseed type, ending the gap by starting the flow of the second oilseed type, and processing the second oilseed type to extract a second oilseed product from the second oilseed type. The gap being effective for preventing substantial commingling of the first oilseed product and the second oilseed product. The method is useful for processing identity preserved oilseeds and genetically modified oilseeds. Product commingling is reduced or eliminated so that the identity preserved products retain their added value. The method for processing oilseeds can be implemented in an oilseed mill by modifying aspects of the processing plant such as the oilseed extractors, desolventizers and material handling equipment.
