Abstract: A physical vapor deposition (PVD) apparatus having a deposition chamber and a source chamber of minimal volume, which can be selectively isolated from each other by a various load-lock valves. Exemplary embodiments can include a tapered high vacuum chamber disposed between the deposition chamber and the source chamber. The pump down time of the apparatus can be reduced, as compared to conventional PVD systems, due to the combined reduced volume of the chambers. Coating uniformity can also be improved by spinning each part to be coated on its' own axis while selectively exposing to a deposition source with minimal particle generation.

Abstract: A method of deducing time based metrics using flow rate is disclosed. The method uses a thermal mass flow meter wherein the meter comprises a pipe housing and a sensor board with at least one heating element and at least two temperature sensors is located inside the pipe and where a microprocessor is programmed to calculate a flow rate based on a logarithmic function of difference between base line temperature difference between temperature sensors before heating element is turned on and a second temperature difference between the temperature sensors after heating element is turned on. Duration of gas supply is provided by using the measured flow rate and information of the gas supply.

Abstract: A cable connector is comprised of at least a first piece including a ferrule having serrations for mechanically connecting with different parts of a coaxial cable, a mandrel and a closing collar. A second piece of the connector is comprised of an entry body including a pin terminal, a support insulator and an actuator. Additionally, the connector provides a visual determination of the complete mating of one piece of the connector to the other.

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.

Abstract: Apparatus for automatically and rapidly transferring precise, accurate multiple quantities of samples, such as blood serum, reagent to a rotatable disc of a centrifugal analyzer.

Abstract: Apparatus for measuring the radioactivity of the contents of a plurality of receptacles supported in a rotatable ring.
