Patent CA-2083966-A1 (CA)
Title: Folding portable lounger
Inventor: LEVY LIONEL
IPC: A47C19/12
Filed: 1991-05-29
Abstract: A folding lounger with a frame having parallel longitudinal elements (1, 2, 31, 32) each of which is provided with two hinges (3, 4, 33, 34) defining a central portion (35) forming the seat to which are hinged folding legs (38, 39). The frame also has an upper portion and a lower portion each of which includes a fabric stretched between the two longitudinal elements, as well as at least two supporting crossbars (5, 6, 310, 311) arranged one at each end of said frame. The folding legs are mounted at each end of said seat (35) on joints fastened to the respective hinges (3, 4, 33, 34), said joints being provided so that the folded legs can be juxtaposed in pairs. Said support bars (5, 6, 310, 311) are provided with a joint (27, 312) so they can lie alongside the longitudinal elements (1, 2, 31, 32) to allow them to be brought together on folding, whereby the fabric becomes slack and lies outside the structure to avoid being damaged when the lounger is fully folded. The lounger further comprises locking devices for locking and stabilizing the chair when it is fully unfolded and ready for use.
Patent CA-2084532-A1 (CA)
Inventor: CHEMELLI JOHN B
IPC: B01L3/00
Filed: 1992-12-04
Abstract: There is described a method for forcing liquid out of a burstable compartment into a detection chamber without also forcing residual air of that compartment to interfere with liquid detection. The method features applying pressure sufficient to eject the liquid but not the residual air, and retaining that pressure as long as the reaction period of the liquid takes place, called the incubation period, and then completing the ejection to eject residual air into the chamber.
Patent CA-2084754-A1 (CA)
Inventor: STONE-ELANDER SHARON A
IPC: H05B6/64
Filed: 1991-06-12
Abstract: A microwave device for treating process liquids, preferably precursors to radiopharmaceuticals, with microwave radiation, with the intention of reducing reaction time and increasing reaction yield.  The method and the device are characterized in that the geometry of the microwave cavity is varied proportionally to the geometry of the sample container in order to concentrate the microwave field within the container. The reaction time can also be shortened and the reaction yield also increased by varying the microwave field energy or microwave field frequency. The reaction time can also be decreased by adding salts to the process liquid or by adapting the frequency of the microwave field to the resonance frequency of the process liquid in the microwave spectrum.

Abstract: The present disclosure relates to improved methods for the preparation of aluminum phosphate molecular sieves and fau-jasite-type zeolites having stably encapsulated multidentate metal chelate complexes. This is achieved through direct incorpora-tion of a selected multidentate chelate complex into the molecular sieve or zeolite reaction admixture prior to crystallization, al-lowing the admixture to react under conditions appropriate for the selected molecular sieve or zeolite, followed by preparation of the resultant molecular sieve-metal chelate complex in a highly crystalline form.

Title: Method & apparatus for manufacture of plastic refrigerator liners
Inventor: WILLIAMS STEPHEN G
IPC: F25D23/06
Filed: 1993-05-10
Abstract: Plaques are formed on the sidewalls of the liner in a refrigerator to reduce thermally induced bowing of the cabinet.        The plaques may consist of indentations in the liner, which in a preferred form are rectangular, or arrays of multiplanar indentations. The plaques provide increased surface area in the liner to permit thermal expansion without bowing, and also increase the structural rigidity of the liner to resist bowing.        Thermal bowing is encountered where there are long unsupported wall surfaces and high temperature gradients across the wall.        Therefore the plaques are very effective in the freezer compartment of a side-by-side refrigerator, where bowing can be severe in the absence of the disclosed corrective measure.

Inventor: NAKAZAWA KENZO
IPC: H01M8/06
Filed: 1993-06-15
Abstract: The reforming method for a fuel cell power  generation system comprises the steps of  feeding the raw material gas to a main reformer to reform the raw material gas to the fuel gas, feeding the fuel gas to the fuel electrode of the fuel cell, introducing to a second reformer non-reformed raw material gas contained in a gas discharged from the fuel electrode, and reforming the non-reformed raw material gas  with hydrogen produced upon a reaction at the fuel electrode of the fuel cell and a sensible heat of the gas discharged from the fuel electrode.          This reduces an amount of non-reformed raw material gas in the system and improves a reforming conversion ratio of the system as a whole.

Filed: 1994-02-21
Abstract: TITLE                PARALLEL-AXIS DIFFERENTIAL WITH    TRIPLET COMBINATION GEARS            ABSTRACT    The preferred embodiments of the invention disclose an automotive torque-proportioning differential of the parallel-axis type having two planetary sets of either three or four combination gears in mesh with sun/side gears that receive respective vehicle axle ends.  Each respective combination gear in each set is in meshing engagement with both (a) a respective one of the differential's two sun gears and (b) at least one other combination gear of its set.  As compared with the planetary gearing of conventional differentials of similar size and torque-proportioning characteristics, the widely-separated sets of planetary gears occupy remarkably less interior space in the housing, permitting (i) the use of unconventionally large housing windows that significantly reduce the weight of the differential and greatly facilitate lubrication of the differential's gearing, and/or (ii) accommodation of C-clip assembly for the axle ends without increasing the exterior dimensions of the differential.  In one embodiment, the center combination gear of each planetary set is designed with a larger diameter than the respective diameters of the two outer combination gears of the set.
