Title: Apparatus and method for maintaining and treating biological cells
Inventor: ROECKER DAVID W
IPC: C12N5/071
Filed: 1996-06-07
Abstract: An apparatus and related method are disclosed, for receiving, maintaining and growing biological cells ex vivo within a portable cassette, without exposing the cells to the external environment. The portable cassette is used in combination with a processor instrument that facilitates an initial inoculation of the cassette with cells of the kind to be grown and to distribute those cells in a predeterminded pattern (e.g., uniformly) throughout a cell growth chamber. Thereafter, the portable cassette is used in combination with an incubator instrument that incubates the cell growth chamber so that the cells are optimally expanded. The same processor instrument then is used to harvest the expanded cells from the portable cassette. Both instruments are configured to condition the portable cassette during stages of the cell growth process, without disturbing the cassette's sterile system. In addition, an updatable memory device associated with the cassette stores significant information about the cassette and its condition during the various steps of the cell growth process. Such information is useful both for subsequent archival purposes and for facilitating a resumption of the cell growth process in the event of any instrument failure or significant alarm condition.
Patent CA-2226498-A1 (CA)
Title: Electrical power control system
Inventor: LAWRENCE JOHN ARTHUR
IPC: H05B41/16
Filed: 1995-07-20
Abstract: The present invention relates to an electrical power control circuit for loads such as fluorescent lighting systems. A winding (3) has a positive end (13) connected to a positive rail (1) and is tapped at a predetermined position (18) for supplying an output terminal (T) with a selected voltage. A first relay contact (200A) can electrically connect a neutral end (14) of the winding to a neutral rail (2) to provide one selected voltage or a second relay contact (100A) can electrically short-circuit a predetermined number of turns of the winding in response to a request for a second selected voltage.  When a fault condition is monitored, a third relay contact (300A) can electrically short-circuit the neutral end (14) of the winding to said predetermined position (18) to put the system into a failsafe condition which prevents turns of the winding being open circuit.

Title: Process and installation for developing a gaseous mixture comprising a carrier gas, an oxidizing gas and a silane
Inventor: INIZAN MICHEL
IPC: B01F23/10
Filed: 1998-01-14
Abstract: The process forms a gaseous mixture of predetermined composition, containing a carrier gas, oxidant and silane. A primary gas mixture is formed from a second neutral gas and the silane. The silane content is below the spontaneous flammability limit of silane in air. A first gas stream is prepared, comprising carrier gas with controlled oxidant gas residual. The required mixture is achieved as a function of the residual oxidant content in the carrier gas stream.   Also claimed are: (i) the plant for the above process; and (ii) gaseous mixtures formed by the above process.

Inventor: KRAJNC JOZEF
IPC: B65D47/08
Filed: 1998-02-17
Abstract: A tamper evident flip top pouring closure is designed for use with a corresponding container.  A tamper evident flip top pouring closure and container in combination has a closure with a screw thread thereon together with interlocking means and a container with the corresponding screw thread and corresponding interlocking means.  The interlocking means prevents the removal of the closure from the container once the closure is installed on the container.  The interlocking means on the closure are a series of tabs that are connected to the closure and extend inward at an angle.  The interlocking means on the closure are two sets of saw-teeth having a gentle slope on one side and a steep slope on another side.  The closure is then installed on the container and cannot be removed because the tabs abutt a steep slope of the saw-teeth and will not override the saw-teeth in a reverse direction.

Title: Collider
Inventor: PIERCE MELVIN E
IPC: B02C13/02
Filed: 1998-09-22
Abstract: A material collider system for reducing the size of solid particulate material fed into the system is disclosed. The collider system includes a pair of interconnected cylindrical chambers each having a rotatable rotor assembly which includes a plurality of disc sets and rigidly mounted thrust guides. The rotor assemblies are aligned in parallel relation and operate in a counter rotating manner. The thrust guides are mounted to the disc sets so as to extend radially outwardly of the disc sets and each thrust guide is maintained in a substantially rigid position by a shear pin. In one embodiment, the thrust guides of the two rotors are arranged in an alternating, interdigitating pattern.      The disc sets may be offset along the length of the rotor assemblies such that the thrust guides form a 360 degree spiral pattern. The rotor assemblies are operated by motors secured outside of the chambers. Sealing means prevent materials from escaping the chambers and causing damage to the drive system of the material collider.

Title: Methods for the isolation and proliferation of insulin-secreting cells
Inventor: SOON-SHIONG PATRICK
IPC: C12Q1/24
Filed: 1997-06-24
Abstract: Methods have been developed for isolating and proliferating insulin-secreting mammalian cells. Invention methods involve isolating insulin-secreting cells and preparing a primary culture in which insulin is secreted under the control of one or more insulin promoter transcription factors, e.g., NKX 6.1, HNF3-beta, STF-1, Beta 2, and the like. Such proliferated insulin-secreting cells are distinguished from all other cells in that they are proliferated and in that they have measurable intracellular levels of one or more transcription factors associated with insulin production, as can readily be determined by suitable assays.

Inventor: BIRKERT ARNDT
IPC: B21D26/02
Filed: 1999-03-22
Abstract: The invention relates to a method for shaping a hollow body from a tubular blank inserted into a shaping tool that can be opened and closed, by internal high pressure introduced into the interior of the blank. The cross section of the blank, prior to the internal high-pressure shaping, can be changed and pre-shaped from a round or rectangular shape, depending on the workpiece. In order to be able to produce workpieces with a circumference that varies considerably over the length without overstretching the material, according to the invention, for pre-shaping the blank, a dent that differs in depth over its length is formed in the blank. During the internal high-pressure shaping of the pre-shaped blank to form a hollow body, a U-shaped fold is formed from the dent that projects into the interior of the hollow body, with the walls of the fold abutting one another directly and merging at the periphery with the circumferential wall of the hollow body. The two walls of the fold are permanently connected to one another and the two walls of the fold are preferably permanently welded together in the vicinity of the circumference of the hollow body.

Title: Plasma arc torch and method using contact starting system
Inventor: LU ZHIPENG
IPC: H05H1/34
Filed: 1997-09-17
Abstract: Disclosed is a novel method and structure for contact starting a plasma arc torch. A translatable, electrically conductive component such as a nozzle or swirl ring is biased into contact with an electrode by a compliant spring element. A pilot arc is formed by first passing current through the electrode/component interface. Thereafter, the component is translated under the influence of gas pressure in a plasma chamber formed between the electrode and component, compressing the compliant element and initiating the pilot arc. The spring element may be a separate element or may be maintained integrally with the nozzle, swirl ring, or a retaining cap, facilitating removal and replacement of the spring element with consumable components of the torch.
