Title: Hermetically sealed scroll type refrigerant compressor with a shaft seal mechanism
Inventor: KIKUCHI KAZUTO
IPC: F04C18/02
Filed: 1989-12-13
Abstract: ABSTRACT OF THE DISCLOSURE      A shaft seal mechanism for a vertically installed hermetic type scroll compressor in which the interior of the housing is kept at discharge pressure is disclosed. The compressor in accordance with one embodiment of the present invention includes a drive shaft sup-ported by a plain bearing in an inner block member. The drive shaft is operatively linked to an orbiting scroll which orbits within a sta-tionary scroll. An isolated cavity is defined within the compressor housing by the stationary scroll and the inner block member. A spiral element of both the stationary and orbiting scrolls, a driving mecha-nism and a rotation preventing mechanism are disposed within the isolated cavity. The isolated cavity is divided into an upper and lower subcavities by an end plate of the orbiting scroll. A small aperture is axially formed through the end plate of the orbiting scroll to intro-duce the intermediately compressed refrigerant gas into the lower subcavity from an intermediately located fluid pocket defined by spi-ral elements. Mechanical seals are disposed within the lower isolated cavity and are mounted around the drive shaft, thereby preventing the discharged refrigerant gas from flowing from the inner chamber into the lower isolated subcavity. Therefore, the axially urging force which upwardly acts on the orbiting scroll due to the intermediate refrigerant gas pressure is maintained, thereby obtaining an appropri-ate axial seal of the fluid pockets of the scrolls. In a second embodi-ment, the isolated cavity is maintained at the suction pressure and is not divided into subcavities.

Title: Device and method for separation of plasma from blood and determination of blood analytes
Inventor: THAKORE YATIN B
IPC: B01L3/00
Filed: 1990-06-26
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention involves a method and device for obtaining plasma from whole blood and determining one or more analytes contained therein.  A sample of blood is first applied to a physical transport medium which moves at least a portion of the blood from a remote location thereon to a second location thereon to a first surface of a microporous plasma separation membrane.  This movement is achieved by gravity, absorption or capillary action and the physical transport medium may be a sheet of fabric with weave or otherwise or a channeled or grooved synthetic material.  Once the blood has moved to the first surface of the microporous plasma separation membrane, the plasma is absorbed and passes through the membrane, thereby separated from the whole blood (and the red color).  The plasma reaches the second (opposite) surface of the microporous plasma separation membrane and contacts a plasma collecting test membrane.  This test membrane is capable of reacting with the plasma (i.e. one of its components) to display at least one analyte characteristic thereof.  Preferably, colori-metric reaction takes place and color intensity indicates concentration level of the analyte in the blood.

Abstract: ADAPTIVE CONTROL OF AN AUTOMATIC TRANSMISSION          ABSTRACT OF THE DISCLOSURE        In an automatic transmission upshifting is controlled by ramping down the pressure in an off-going clutch associated with a high speed ratio and increasing the pressure in an on-coming clutch associated with a lower speed ratio.  The on-coming clutch has commanded pressure at a maximum value for an initial fill time, a lower increasing ramp value during the ramp of the off-going clutch until the on-coming clutch starts to engage, and then a closed-loop control until the clutch reaches a synchronous speed.  The closed-loop control parameter is on-coming clutch slip which is controlled to a calculated slip speed profile. Parameters for controlling the quality of a shift such as on-coming clutch initial pressure, off-going clutch initial pressure and on-coming clutch fill time are automatically adjustable during vehicle use to correct shift aberrations which degrade shift quality.  A fast adjustment mode is in effect initially to calibrate the transmission control for the engine and vehicle.  After a smooth shift is obtained only small adjustments are allowed.

Abstract: HYDRAULIC POSITIONING SYSTEM FOR A     HYDRAULIC TURBINE GOVERNOR                            ABSTRACT The hydraulic piston cylinder assembly which operates the governor of a turbine which powers a hydropower generator has a servo valve capable of flowing only a portion of its flow requirements during normal low power fluctuation conditions of the turbine's operation. During high power fluctuation conditions of the turbine's operation, such as during start-up, hydraulic fluid also flows to and from the piston and cylinder assemblies through high flow pressure and return conduits that bypass the servo valve.  Control of fluid flow in the high flow conduits is accomplished by a proportional throttling valve located in the high flow return line. The servo valve and proportional throttling valve together have a flow capacity which is equal to the flow requirements of the piston and cylinder assembly and they are both actuated by the same electronic controller. However, the electronic controller only actuates the proportional throttling valve when the flow requirement of the piston and cylinder assembly exceeds the flow capacity of the servo valve.  A hydraulic logic circuit activated by the electronic controller allows the high flow pressure and return conduits to be reversed for two-way operation of the piston and cylinder assembly.
