Title: Height adjustable conveyor system
Inventor: SIMKOWSKI DONALD J
IPC: B65G51/03
Filed: 1995-05-17
Abstract: A height adjustable conveyor system is disclosed for conveying articles between different heights as needed.          The conveyor system includes guides that support the neck rings of articles to be conveyed, and the guides are mounted on an air conveyor having multiple sections so that the guides are caused to be flexed by different movements of the air conveyor sections.  The air conveyor has pivotably coupled first, second and third sections with the first section being vertically adjustable with respect to the third section and the second section being between and tiltable with respect to the first and third sections to thereby flex the guides as necessary to readily effect article height variations as needed between the input and output of the system.  Relative movement between the three sections of the air conveyor is effected by a lever pivotably connected with a fixed support and the first section of the air conveyor with the lever being actuated by a crank.

Title: Automated inspection system with transport and ejector conveyor
Inventor: EBEL JAMES ANDREW
IPC: B65G43/08
Filed: 1995-05-30
Abstract: An automated inspection system for inspecting packages, such as blister packages, to verify the presence therein of products, such as contact lenses, prior to heat sealing of the blister packages. The automated inspection system includes a transport and ejector mechanism for ejecting any defective packages determined by the automated inspection system not to have a product therein. The automated inspection system includes an optical inspection station at which packages are optically inspected by video cameras to verify that a product is, in fact, present in each package base. A package conveyor system is provided for conveying the packages by the optical inspection station. Following the optical inspection station, an ejector ramp of the transport and ejector mechanism is selectively switchable between a first raised position in which package bases are passed on for further processing, and a second lowered position in which defective packages are transferred from the package conveyor system to the ejector ramp and a buffer area for ejected packages. In a disclosed embodiment, each package base is part of a linear array of six connected package bases, and the optical inspection station includes three video cameras placed in a series along the package conveyor system.      Each video camera optically examines an adjacent two connected package bases, such that the three video cameras simultaneously optically examine all six connected package bases in each linear array.

Title: Hybrid fiber amplifier
Inventor: BUTTON LESLIE JAMES
IPC: H01S3/067
Filed: 1995-06-22
Abstract: The present invention relates to a multi-wavelength multi-stage fiber amplifier exhibiting high power output with a flat balanced gain spectrum. The input stage exhibits a given passive loss and a flattened gain spectrum.  The output stage exhibits a passive loss that is lower than the given passive loss and a gain spectrum that is less flat than the gain spectrum of the input stage.  In a system utilizing erbium-based gain fibers, the input stage gain fiber can contain an amount of alumina sufficient to provide the desired gain spectrum flatness, while the output stage gain fiber has an alumina concentration sufficiently low to render that stage essentially lossless.

Title: Method and apparatus for forming ethylene or ethane and ethylene from methane
Inventor: VAYENAS CONSTANTINOS G
IPC: C07C2/84
Filed: 1994-01-28
Abstract: The invention refers to the oxidative dimerization of methane to ethylene or to ethane and ethylene via successive and repeated contact of a methane-oxygen gas mixture with a suitable catalyst and with a porous adsorbent or absorbent material capable of trapping ethane and ethylene, via adsorption or absorption, with intermediate addition of oxygen via a gas feedthrough or electrochemically via a solid electrolyte. The method can be applied both in a recirculating gas apparatus and in a continuous flow apparatus. In the case of the continuous flow apparatus, the gas can be partially recycled and also the solid catalyst or the solid adsorbent or absorbent can be continuously recycle. The ethane and ethylene trapped in the porous adsorbent or absorbent at a temperature lower than that of the catalyst is subsequently released via heating while a second trap or recycled solid trapping material is brought in contact with the gaseous mixture and the procedure is repeated continuously. This new invention has already led in the laboratory to ethylene yield in excess of 75 % and to total ethane and ethylene (C2) yields in excess of 80 %.

Patent CA-2160936-A1 (CA)
Inventor: GITTENS TIMOTHY EDGAR
IPC: B23K9/16
Filed: 1995-10-19
Abstract: A weld shield apparatus provides an atmosphere of inert gas within a conduit in an underbead region where an external weld joint is to be produced.  The weld shield apparatus includes a diffuser structure having a convex exterior surface that is defined by a wall structure, the convex exterior surface is shaped to fit within the conduit and to be separated from an inner wall of the conduit by a clearance space.  The diffuser wall structure is comprised of a porous material which enables gas communication between an inlet to the diffuser and the convex exterior surface.  A seal is positioned immediately upstream from the diffuser structure and is positioned to engage the inner walls of the conduit so as to prevent the passage of gas in an upstream direction.  A source of gas is coupled to the inlet to the diffuser structure and enables inert gas to pass through the porous material and to flow in a laminar manner, via the clearance space, past the underbead region and into the downstream region of the conduit.  The resulting laminar flow and use of a neutral density gas enable small amounts of gas to be employed as a weld shield.

Title: Analyte detection from steady-state luminescence lifetime
Inventor: ZUCKERMAN RALPH
IPC: A61B10/00
Filed: 1995-04-19
Abstract: Methods and apparatus determine analyte concentradon in vivo and in vitro by the steady state determination of luminescence lifetime. A fluoro-phore that is quenched by the analyte is free to undergo Brownian rotation. The fluoro-phore (12) is irradiated with continuous linearly polarized light (24). Emitted luminescence is resolved into vector components parallel and perpendicular to the plane of polarization of the excitation light (36, 38). A mathematical function is employed which relates the luminescence anisotropy to quencher concentration. For analytes which do not quench excited staves, a known quantity of the analyte is conjugated to a quencher molecule or energy transfer acceptor, and a competition reaction is set up in which labelled and unlabelled analytes compete for sites on a labelled carrier molecule. An empirically determined mathematical function is employed which relates luminescence anisotropy at the carrier label emission band to analyte concentration.
