Abstract: A process for preparing polymer electrets comprising the following steps:(a) providing a parylene film having one side affixed to a metal layer and grounding said metal layer;(b) charging the free side of the film with a direct current corona, the charge being of sufficient magnitude to convert the film to an electret;(c) providing p-xylylene monomer vapor in sufficient amount to coat the charged film; and(d) introducing the vapor from step (c) and the electret into a deposition zone, said zone being under vacuum and at a temperature at which the vapor will condense, whereby the electret is conformally coated with parylene.

Abstract: A process for preparing polymer electrets comprising the following steps:(a) providing two electrodes in a deposition zone, said electrodes being in a spaced relationship to one another, having opposing surfaces, and being connected to an external voltage source capable of impressing an intense electric field between the opposing surfaces;(b) providing a dipolar substituted p-xylylene monomer vapor in sufficient amount to coat the opposing surfaces of the electrodes;(c) activating the power source; and(d) introducing the vapor from step (b) into the deposition zone, said zone being under vacuum and at a temperature at which the vapor will condense,whereby the vapor condenses on the opposing surfaces of the electrodes, the monomer polymerizing to parylene, coating said surfaces, and forming electrets.

Abstract: A 2:1 compensating rotor is used in a continuous-flow centrifuge system, thereby allowing the dynamic loading and unloading of biological suspensions and processing solutions in a "closed" fashion without resort to rotary seals. Improved performance is obtained by relieving the mechanical stresses associated with the 2:1 relative motion between rotary components. In zones of high flexural and torsional stress low-friction bearing mounted tube constraint fittings are utilized to minimize tubing loop wear and risk of rupture. Similarly, in regions of high centrifugal force a tube guide insert is utilized to separate and constrain the discrete fluid-carrying tubes, thereby minimizing abrasion induced by the relative motion between the discrete tubes, as well as minimizing abrasion induced by the relative motion between the discrete tubes and the inner walls of the tube guide assembly.

Abstract: Transverse radionuclide scan field imaging apparatus and method using highly focused collimators in an array surrounding the scan field.

Abstract: A transverse radionuclide scan field imaging apparatus comprises a plurality of highly focused, closely laterally adjacent collimators inwardly focused in a rotatable array which surrounds a scan field, with each collimator being movable relative to its adjacent collimator. For each scan position, the focal point of each collimator uniformly samples at least one half of the scan field.

Abstract: Vanadium-carbon materials for use as additions to steel have been produced by the vacuum furnacing of a mixture of vanadium oxide and carbon. To lower the sulfur content of such material, which derives essentially from the sulfur content of the carbon in the mixture, a relatively small quantity of silicon, silica or tin is included in the mixture prior to vacuum furnacing.

Abstract: A 2:1 compensating rotor is used in a continuous-flow centrifuge system, thereby allowing the dynamic loading and unloading of biological suspensions and processing solutions in a "closed" fashion without resort to rotary seals. Improved high speed performance is obtained by utilization of an inherently symmetrical load sharing epicyclic reverted gear train. The effective lifetime of the component gears is increased due to the load sharing feature of the symmetrical epicyclic reverted gear train.
