IPC: B29C45/16
Filed: 1992-05-11
Abstract: Valve gated injection molding apparatus for coinjecting and/or sequentially injecting two different fluids through a gate (20) into a cavity (22). An elongated valve pin member (64) is received in an elongated valve sleeve member (56) in alignment with the gate (20) and both are reciprocated rotatably as well as axially by separate actuating mechanisms to control the flow of the fluids through the gate. Each actuating mechanism has a piston driven rack member (96,118) to provide rotary motion which is then converted to axial movement of the corresponding valve member (56,64) between the retracted open and forward closed positions. In one embodiment, helical threads (104,126) on the valve members engage fixed teeth extending inwardly from the surrounding nozzle to convert the rotary motion of each valve member to corresponding axial movement. Linear position transducers on the rack members provide for accurate control of the valve members. This accurate control and the reduction in force required by these rotary axial actuating mechanisms minimizes wear resulting from repeated seating of the valve members. <IMAGE>

Abstract: Méthode permettant de réduire la teneur en huile des croustilles d'aliments, comme les croustilles de pomme de terre et de maïs. La méthode consiste à faire circuler de l'anhydride carbonique liquide au-dessus des croustilles d'aliments pour en extraire l'huile. La teneur en huile peut être réduite de 25 jusqu'à moins de 50 % de sa valeur initiale, tout en conservant une saveur et une texture comparables à celles des croustilles frites classiques qui contiennent de 30 à 40 % d'huile. L'huile récupérée de l'anhydride carbonique liquide utilisé pour l'extraction, dont l'aspect et la qualité sont essentiellement les mêmes que ceux de l'huile de cuisson vierge, peut être réutilisée pour la friture en bain des croustilles.

Title: Methods and apparatus for detecting biological activities in a specimen
Inventor: BERNDT KLAUS W
IPC: C12M1/34
Filed: 1993-03-24
Abstract: ABSTRACT Methods and apparatus for detecting biological activities in a specimen such as blood are disclosed.  The present invention provides a system whereby the intensity of light with a wavelength within the range of about 600 nm to 800 nm introduced into a sample at a first location is measured as it reemerges at a second location.  A significant change in the intensity of the reemerging light indicates the presence of biological activity.  Preferably, the intensity is also measured at a fourth location, or alternatively, a second light source is disposed at a third location to permit comparative intensity data to be collected.  These data are useful in partially identifying the types of microorganisms present in the sample.  In preferred embodiments, light emitting diodes are used as the light sources and multiplexed to a plurality of samples.  These signals are either detected using photodetectors and demultiplexed, or are collected using fiber-optic light guides and fed to a photomultiplier tube which generates an intensity signal.  In either embodiment, the intensity signal is preferably amplified, digitized and stored in a computer.

Title: Supercritical fluid extraction restrictor and collection system
Inventor: DURST KEVIN
IPC: C07C15/20
Filed: 1991-09-19
Abstract: A system of recovering at least one low molecular weight chemical compound carried in the high pressure effluent fluid stream from supercritical fluid extraction. This effluent stream flows through a heated capillary conduit (52) preferably including a coiled segment in a heat conductive bloc (56). A flow restrictor in the conduit restricts flow and thereby slowly reduces pressure to exit a port (52d) into a region free of liquid in a decompression zone (70) thereby substantially decompressing said high pressure effluent fluid stream. Then the stream is passed into a liquid solvent zone (74) containing a liquid solvent for a low molecular weight chemical compound. Then, the low molecular weight chemical compound in said liquid solvent is trapped and detected. When the effluent fluid stream contains at least one high molecular weight compound, it is deposited on a surface in contact with said gas decompression zone, removed, and detected.
