Patent CA-1299237-C (CA)
Inventor: TROCCIOLA JOHN C
IPC: H01M8/04
Filed: 1988-03-23
Granted: 1992-04-21
Abstract: Abstract Fuel Cell Configuration for Contaminated Fuel Gases and Method of Using the Same The fuel cell system is adapted to be able to operate with oxygen-contaminated hydrogen-rich fuel gases without experiencing undesirably high temperature hot spots on the fuel cell electrodes.  Oxygen in the fuel gas is catalytically burned in areas of the electrodes where no electrochemical reaction occurs. The oxygen content of the fuel gases is thus reduced to an acceptable level before the fuel gases flow over the portions of the electrodes which are electrochemically active.  Anode exhaust can also be partially recirculated into the anode inlet to mix with incoming fuel gas thereby preliminarily diluting the amount of oxygen in the incoming fuel gases.

Title: Security gate operable with one hand

Granted: 1992-09-08
Abstract: SECURITY GATE OPERABLE WITH ONE HAND                   Inventor:  Carl M. Stern ABSTRACT OF THE DISCLOSURE         A security gate includes an installation and release mechanism that is operable with one hand.  The gate comprises two panels which are extendible with respect to each other and lockable in the extended position.  This makes it possible for the gate to expand across a wide variety of door openings.  A handle located centrally on the top of the gate is connected by a pair of cranks and a pull rod to a pair of plungers which contact one side of the door frame.  Spring bias on the plungers normally force the plungers into contact with the door frame.  Slots in the upper and lower plunger links permit the plungers to accommodate irregular door frames.  The handle is employed to withdraw the plungers from contact with the door frames and, conversely, the absence of handle pressure causes the gate to position itself solidly against the vertical door jamb.  The handle is also employed by the operator to carry and position the gate in the doorway, allowing one-handed operation.  A thumb operable handle interlock system prevents the handle from being accidentally manipulated unless one of two release interlock buttons is depressed by the thumb of the user.  Also, the two extended panels are held in position by a second safety interlock which prevents a pair of extension adjustment knobs from rotating unless the extension interlock is released.

Abstract: INVENTOR:   JURG EBERLE          INVENTION:  ENDLESS REVOLVING TRANSPORT APPARATUS FOR PIECE             GOODS                   ABSTRACT OF THE DISCLOSURE             The transport apparatus comprises an endless guide device extending in a closed path and at which there are guided a number of entrainment elements.  These entrainment elements are interconnected by a toothed belt deformed into a substantially wave-shaped configuration by attachment elements secured at the entrainment elements.  At each of the starting region and terminal region of the conveying-active path of the transport apparatus, there are rotatably mounted two parallel cam discs rotatable in a predetermined direction of rotation by related drives.   Recesses in the cam discs act upon the entrainment elements such that the latter are driven at the starting region and terminal region of the conveying-active path and are dispositioned in a predetermined mutual position. The spacing between the entrainment elements at the conveying-active path and at the non conveying active path is compensated by the resilient action of the wave-shaped deformed toothed belt.  Differences in the operating cadence or in the phase position between printed products delivered to the transport apparatus and outfed away therefrom are  compensated by increasing or reducing the spacing between the entrainment elements.

Title: Multi-channel molecular gas analysis by laser-activated raman light scattering
Inventor: VAN WAGENEN RICHARD A
IPC: G01J3/44
Filed: 1988-10-04
Granted: 1993-10-19
Abstract: MULTI-CHANNEL MOLECULAR GAS ANALYSIS BY LASER-ACTIVATED RAMAN LIGHT SCATTERING              Abstract of the Disclosure The concentration of multiple polyatomic gases are determined simultaneously by Raman light scattering. The gas sample is placed in a sampling cell and a polarized laser beam is passed through the cell, along a longitudinal axis.  A portion of the light scattered by the gas sample is captured and detected by means of multiple collection optics-filter detector channels.  The scattered light exits the gas cell via windows located in the sides of the gas cell and enters the collection channels which are aligned with the cell windows.   The cell windows are along the longitudinal axis of the laser beam and gas cell.   Light scattered  by  the  gas  sample  provides  signals  of  both inelastic Raman scattered light and elastic laser scattered light which are directed to the collection channels.  The optics  of  each  channel  transports  the  scattered  light signals  onto  a  laser  line  reflection  filter where  the elastic  scattered  laser  signals  are  attenuated.    The remaining inelastic Raman scattered signals are caused to be incident upon an interference filter which is specific to the transmission of one or more specific Raman lines. The  interference  filter  in  each  collection  channel is selected to a specific wavelength which is characteristic of Raman scattering from a particular polyatomic gas.  The optical  signals  representative  of  these  specific  Raman lines passing through the interference filters are sensed by optical  detectors,  and amplified and converted into digital  electrical  pulses  which  are  processed  into simultaneous visual readouts indicative of the identity and concentration  of  each  of  the  polyatomic  gas  molecules present in the sample of gas being analyzed.

Abstract: ABSTRACT      A practical cryogenic Peltier cooler (22) is devised by replacing one of the semiconducting elements in a con-ventional Peltier cooler with an element comprised of bulk, or thin film superconducting material.  In the pre-ferred embodiment, a rare-earth, a barium copper oxide superconductor (78) of the form Ybacu3Ox is utilized.  The superconducting elements (78) are placed in an alternating series with semiconducting elements (72) comprised of bismuth telluride of the form Bi2Te3 (n-type).  Perform-ance may be improved in an alternative embodiment by util-izing instead a bismuth antimony semiconductor of the form Bi85Sb15 (n-type).  As a result, cryogenic Peltier coolers can be devised with useful refrigeration capacities and stable cold temperatures of 65-80 degrees Kelvin and below, while heat sinked to a higher temperature.
