Abstract: A method for vitrification of a blood vessel includes immersing the blood vessel in increasing concentrations of cryoprotectant solution at a temperature greater than −15° C. to a cryoprotectant concentration sufficient for vitrification; cooling the blood vessel at an average rate of from 30-60° C. per minute to a temperature between −80° C. and the glass transition temperature; and further cooling the blood vessel at an average rate less than 10° C. per minute to a temperature below the glass transition temperature to vitrify the blood vessel. After the vitrified blood vessel has been stored, the blood vessel may be removed from vitrification by warming the blood vessel at an average rate of from 20-40° C. per minute to a temperature between −80° C. and the glass transition temperature; further warming the blood vessel at a rate of from 200-300° C. per minute to a temperature above −15° C.; and reducing the concentration of the cryoprotectant.

Abstract: The invention relates generally to a method of separating swarf lubricant from swarf solids. A centrifuge parts separator utilizes a screen which preferably comprises a cylindrical shaped member formed in one or more component parts with a plurality of spaced fluid passage openings therein with the ratio of the distance between the center lines of adjacent openings (x) and the median width of the openings (y) being x/y of at least 18/1. The swarf is centrifuged in the separator during the course of which operation, substantially all the swarf fluid passes through the screen openings whereas substantially all the swarf solid passes over the screen, the separated swarf fluids and solids each being directed to a collection site.

Abstract: The invention relates generally to a screen used for separating lubricants from solid materials, and more particularly, to a centrifugal parts separator having a screen which assists in separating lubricants from metal or other scrap materials. The screen of the present invention preferably comprises a cylindrical shaped member which can be formed in one or more component parts with a plurality of spaced fluid passage openings therein. The screen is made so that the ratio of the distance between the openings to the median width of the openings is at least 18/1, thereby providing increased surface wear area of the screen.

Abstract: An improved jig screen for a centrifugal jig includes a recovery zone and a stratification zone adjacent to one another. The stratification zone is constructed to prohibit outward radial passage of slurry particles while permitting fluid pulsations to be imparted to the slurry during jig screen rotation. The stratification zone axially leads to the recovery zone. The recovery zone has openings permitting passage of particles in the slurry and through which fluid pulsations are directed to the slurry during jig screen rotation. The combination of applying centrifugal force and fluid pulsations to a pre-stratified slurry more effectively separates the heavy particles passing through the recovery zone of the jig screen from the lightweight particles discharged at its exit end.

C. to about 1600.degree. C., the contacting being carried out such as to convert the primary metal values to oxide residues at commercially acceptable rates and to evolve gaseous fluoride from the feed, digesting said oxide residues in an acidic digest medium and separating the primary metal values from the resulting digest liquor and from other components of the residues.

Abstract: A coaxial cable terminator assembly for coupling a first coaxial cable terminating in a first end and a second coaxial cable terminating in a second end. The assembly comprises a shelf for receiving the first coaxial cable, and a shaft for receiving the second coaxial cable. The shaft is reciprocatingly slidable from a disengaged position wherein the first and second ends are separated, to an engaged position wherein the first and second ends are in contact. The assembly further includes a housing encompassing the shelf, shaft, and ends, and locking means for retaining the shaft in the disengaged position to prevent tampering with the cable ends. The shaft has an extension portion which extends below the housing when the ends are in the engaged or disengaged position to thereby indicate whether the ends are in the engaged or disengaged position.

Abstract: The gemstone recordal and retrieval system records optical images for gemstones in an effective manner. The optical image of a gemstone is captured using a two-dimensional charge coupled device whereby the time to capture the image is relatively short. The optical images can be improved in definition by varying the output of a laser LED. This fast feedback and adjustability provides accurate recordings.

Abstract: An environmentally safe laundry washing apparatus and method includes a primary solids removal system with an inlet for receiving waste wash water which delivers the water to a separation system and then to a main circulation system which has an ozone source and at least one filter. A final water purification batch treatment system capable of greater than 98% total dissolved solids removal in conjunction with a sterilization device is in fluid communication with the main circulation system, and a washing means is located downstream from the final water purification system. The wash water is recirculated from the washing means after the completion of a wash cycle to an inlet of the primary solids removal system.

Abstract: Single or multi-screw indirect-heating screw conveyor desorbers having a heating gas guide enclosed by the screw shaft wall (single-wall screw shafts) or located between a screw shaft wall and an internal chamber wall (double-walled screw shafts). Predetermined amounts of cooling and diluting fluid may be added to a heating gas stream to control the maximum temperature thereof. Screw shaft support bearings and rotary drive components may be cooled, and conveyor wall and/or screw shaft surfaces (e.g.. screw flights and interflight surfaces) may be automatically cleaned during screw shaft rotation by hardened bits and/or breaker devices. Cleaning operations may also involve the interaction of two counter-rotating conveyor screw shafts having mutually interleaved and opposite-handed external flights.
