Title: Transfer port system
Inventor: KENDALL JOHN S
IPC: B01L1/02
Filed: 1997-08-11
Abstract: A transfer port system to allow material to transfer between two dockable sterile environments. Two doors provide access to the sterile environments. A peripheral flange frames one of the doors while another peripheral flange forms the opening to the other sterile environment. Doors connect to one another, when the sterile environments are docked. and then move as a unit into the one sterile environment in order to allow the material transfer. Outer and inner gaskets seal the sterile environments and with the peripheral flanges form an interface between the sterile environments during material transfer. The portions of the gaskets and peripheral flanges that were exposed to the unsterile ambient prior to docking are actively heated in order to maintain sterility during the time when the sterile environments are docked and prior to the time that the doors are moved to the open position. The doors can be connected to one another prior to their opening by vacuum. The vacuum has an added benefit of drawing contaminants from between the doors. <IMAGE>

Metal pins (74) pass through the sides of the wood flanges (52, 54) and the flattened ends (60) of the metal tubes (56) to secure the tubular metal web (58) to the flanges (52, 54). In other embodiments (fig. 6) the web (106) includes oriented strand board (OSB) or plywood. Synthetic reinforcements (86) are adhered to the wood flanges (52, 54) so that the metal pins (74) also pass through the reinforcements (86). The synthetic reinforcements (86) preferably include multiple synthetic fiber strands (90, 92) held within a resin matrix.

IPC: H05B44/00
Filed: 1997-12-17
Abstract: The light-emitting-diode lamp comprises a set of light-emitting diodes, a rectifier and power converter circuit, and a power factor controller. The rectifier and power converter circuit converts ac or dc voltage and current from a power source to dc voltage and current supplied to the set of light emitting diodes. The rectifier and power converter circuit includes an electronic switch through which it is supplied with ac or dc voltage and current from the power source, and an inductor device including windings adapted to charge a capacitor with a voltage signal representative of the amplitude of the ac or dc voltage from the power source. The power factor controller is responsive to the voltage signal across the capacitor for controlling the electronic switch of the rectifier and power converter circuit in view of supplying dc voltage and current to the set of light emitting diodes while maintaining the power factor of the light-emitting-diode lamp equal to or close to unity. The power factor controller comprises a voltage comparator supplied with the voltage signal across the capacitor for enabling operation of the power factor controller as long as the ac or dc voltage from the power source has an amplitude higher than a first predetermined voltage threshold. A voltage boosting circuit raises the amplitude of the voltage signal across the capacitor when the ac or dc voltage from the power source is lower than the first voltage threshold to keep operation of the power factor controller enabled as long as the ac or dc voltage is higher than a second predetermined voltage threshold lower than the first predetermined voltage threshold.

Title: Compressor bleed valve
Inventor: LIU XIAOLIU
IPC: F04D27/02
Filed: 1998-02-13
Abstract: A bleed valve is in fluid communication with the compressor fluid flow path and the bypass fluid flow path whereby a piston extends radially of the valve and includes a piston head radially remote from the compressor fluid flow path. A pneumatic chamber surrounds a portion of the piston head, and air from a source downstream of the impeller is introduced into the chamber. The piston including a valuing member and a rigid sleeve connecting the piston head to the valuing means opens or closes the communication between the compressor flow path and the bypass flow path. A precompressed spring is associated with the piston to normally urge the piston radially outwardly relative to the compressor fluid flow path to a valve open position, and when the pneumatic pressure in the chamber surrounding the piston head overcomes the precompressed spring, the valve is closed.

Title: A method and system for accessing carrier data
Inventor: CARROLL TERRI A
IPC: G06F9/44
Filed: 1998-09-25
Abstract: The invention is a method and system of loading a data object representative of carrier data and possible command structures, which can be identified by both name and date fields characteristics, into a Data Access System of a carrier management system. The method begins with receiving a request for an object and then determining whether or not the object resides in a first data table which is indicative of a plurality of characteristics of the object. If the object is not resident in the first data table, then the system assigns an initial time stamp and a permanence value to the object. Additionally, the method and system must determine the memory space, in the Data Access System, required for storing the object. De-referenced objects are removed from the memory until space is available that is greater than or equal to the memory requirement of the object. After memory is allocated to the object, the object is then loaded into the memory for use within the carrier management system. A directory table is then established for the object. The directory table includes: an object name; a set of associated data; and, an object table data pointer. The associated data includes an effective date; an expiration date; and, the modification status of the file.
