Abstract: A method of manufacturing a concentrate from juice that may be used to make a powder that can be reconstituted as a juice drink by addition of water to the powder or to make a taffy-like solid that may be consumed without being reconstituted and in which the juice is freeze or spray dried, includes the use of lubricants and/or dextran to improve the texture of the dried juice so that it may be packaged and stored for later consumption.

Abstract: A method of manufacturing a powder that may be reconstituted as a fruit drink by addition of water to the powder includes the use of dextran as a drying agent for the fruit juice that is to be rendered to powder. The dextran should be of high purity and have a predetermined molecular weight in the range of 10,000 to 40,000,000. The amount of dextran dissolved in the fruit juice may range from about one-tenth to equal parts by weight of the total carbohydrate content of the fruit juice, and is inversely related to the predetermined molecular weight.

Abstract: A superfusion apparatus for the controlled reaction of a sample within a test chamber through controlled exposure to a series of reagents in a set test sequence is provided for electrical or chemical stimulation to determine if a receptor binding compound is an agonist or antagonist. The superfusion apparatus provides a mass production but meticulously controlled sample environment for controlling temperature, quantity and arrangement of reagents and wash fluids to provide a high reproducability of results which may be compuer assisted. The device has a fully automated mode or a manually operated mode. The fully automated mode allows for the storage and execution of a number of different tests to be performed on the samples due to the provision of desired sequences of test parameters.

Abstract: A multi-layered cell harvester having a multi-layered top section and multi-layered bottom section with holes and channels formed in the multiple layers along with vacuum and wash manifolds is provided for removing, filtering and washing the contents from test tubes in a standard test tube rack. The novel multi-layered cell harvester precisely controls an equal volume of wash fluid or reagent to the test tubes and each of the filter areas on a sheet of filter paper areas on a sheet of filter paper by utilizing a wash fluid or reagent reservoir having a purge means and wash channels of equal length formed in the multi layers from the reservoir to the tip of each wash needle where the diameter of each wash channel is the same, or by increasing the diameter of some of the wash channels or a combination thereof. The multi-layered cell harvester can include provisions for separately handling radioactive materials and saving the mother liquid and wash fluids or reagents.

Abstract: In this vehicle height adjustment system, a plurality of actuator assemblies are provided, one corresponding to each one of the vehicle wheels and resiliently suspending it from the vehicle body. These actuator assemblies have pressure chambers, and each is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding wheel as respective results of supplying or discharging of working fluid to or from its pressure chamber. Working fluid supply/discharge means are provided corresponding to the actuator assemblies and supply and discharge working fluid to and from their pressure chambers. Vehicle height detection means are provided for sensing the heights of the vehicle above the wheels. A means detects the rate of change of the steering angle of the vehicle.

Abstract: A method and apparatus for the simultaneous filtering of samples contained in a plurality of test tubes includes a test tube block, a vacuum manifold, base manifold and vacuum base. The vacuum manifold is provided with a plurality of recesses complementary with barrels in the block defining chambers to receive the test tubes. The base manifold and vacuum base are assembled as a unit including recesses to receive filter screens and passages leading from the recesses to a vacuum source. The vacuum manifold is positioned onto the block with a filter medium placed over the vacuum manifold and secured in place by attaching the base manifold/vacuum base unit to the block. When vacuum is applied to the vacuum base the entire assembly is inverted whereby the contents of the test tubes are drawn through passages in the vacuum base to the filter medium. Passages in the base provide a wash solution to the barrels which is drawn through the device by the vacuum.

Abstract: Body fluid pressure is monitored by implanting a sensor in the body which is responsive to the pressure therein. The sensor communicates with radiopaque means which changes its position when there is an abnormal amount of pressure as compared to a normal amount of pressure whereby the change can thereby be detected by X-Ray and translated into a value indicative of the pressure, thereby permitting serial, comparative, reliable and permanent recording in a relatively inexpensive manner.

Abstract: A surgical sponge collector and drainage system includes a tray having a smooth concave wall contoured for fitting directly against the human body and mounted in contact therewith. The tray includes a perforated shelf disposed below its peripheral rim as a discard area for collecting used sponges and permitting liquid to drain therethrough and ultimately drain to a collector. Aspirating tubes are also provided and inserted into the body at the operation site for withdrawing liquid therefrom into the same collector as from the tray.
