Patent CA-2087680-A1 (CA)
Inventor: LONG ERWIN L
IPC: E01C11/26
Filed: 1993-01-20
Abstract: A method and a device for warming the surface of a road. The device comprises a sealed thermosyphon having an elongated condenser unit adapted to be positioned on an insulated layer just below a road surface. The device further includes an evaporator containing an easily evaporatable liquid, which is connected to the condenser and situated at a lower level thereto. When the temperature of the evaporator is above the boiling point of the liquid, the liquid will evaporate and the condensed vapor will move up into the condenser where it will condense and flow back down to the vaporizer. The condensation of the liquid causes heat to be transferred from the device to the area adjacent the road surface.

Patent CA-2093710-A1 (CA)
Inventor: ABYS JOSEPH ANTHONY
IPC: G01N27/26
Filed: 1993-04-30
Abstract: This invention pertains to an apparatus and method for measuring throwing power of electroplating solutions. The apparatus is easy to use and gives reproducible measurements.  The apparatus emulates the performance of a conventional Haring Blum cell. The major disadvantage of the standard Haring Blum cell is its limited aility to vary the solution mass transport, thus limiting its applicability to very low current density applications. Furthermore, even under low-mass transport conditions, non-uniform solution distribution is experienced leading to erroneous interpretation. This invention permits the study of throwing power of electroplating solutions under a whole variety of solution agitation. The invention embodies an instrument for and a method of measuring the throwing power of electrolytes. The instrument is in a form of an elongated cylindrical body adapted for rotation about its longitudinal axis and includes a fixed conductive anode element and at least two cathode elements, at least one of which is variably spaced from the anode element. Preferably, one cathode element is fixed relative to theanode element a first predetermined distance and another cathode element is spaced from the anode element a second variable distance which is a multiple of the first distance.  The instrument also includes means for providing current to the anodeelement and equi-potentially to each of the cathode elements. The measuring includes providing each of the cathode elements with a pre-weighed removable metal foil, rotating the instrument which the anode and cathode elements are completely submerged in an electrolyte, applying current to the anode and the cathode elements, removing the metal foils from the cathode elements and weighing the metal foils with the deposit thereon to compare the weight of deposited metal at different cathode element positions.

Patent CA-2095027-A1 (CA)
Title: Method and apparatus for monochannel simultaneous heat and mass transfer
Inventor: ALBERS WALTER F
IPC: B01D5/00
Filed: 1991-10-22
Abstract: A method and apparatus for heat and mass transfer is described that is applicable to: regeneration of liquid dessicant solutions, heat pumping of humid gases, cooling and dehumidifying of gases for air conditioning, and water absorption from air. Generally, using a moving gas (12), at a constant pressure, a continual change in a vapor-liquid equilibrium is created between proximate but continually changing gas and liquid desiccant temperatures within an energy transferring chamber. Chamber wetting, implemented segmentedly (38, 40, 42), allows mass transfer into and from the moving gas. A forced temperature differential between heat sinks (62) and sources (72) causes heat transferred by means of thermally conductive barriers. Concurrent with temperature variances, the segmented wetting further allows liquid desiccant (44) concentrations caused by evaporation or condensation, to vary between wetted sectors (38, 40, 42). A migratory movement connecting these wetted sectors provides for development of applicable concentration gradients between the wetted sectors along the chamber length.

Abstract: STACKABLE & REVERSIBLE PALLET           ABSTRACT OF THE DISCLOSURE        A rectangular shipping pallet for use in forming a shipping package is disclosed. A pair of like pallets and a packaging sleeve are used to form a shipping package, so that the pallets form the top and the bottom of the shipping package and the packaging sleeve forms the sides of said shipping package. The pallet comprises a base member having first and second opposed end edges and first and second opposed side edges which form corners therebetween, and a generally vertically disposed wall member located at the periphery of the base member. The vertically disposed wall member has a first free edge and a second edge, and forms a retention surface to retain an end portion of the packaging sleeve to substantially preclude horizontal movement of the packaging sleeve with respect to the base member. There is     an inclined locating surface which intersects the second edge of the vertically disposed wall member, so that the end portion of the packaging sleeve is urged toward the vertically disposed wall member upon mating of the packaging sleeve and the locating surface. Several different configurations of feet are disclosed so that the pallet may be nested with like pallets or stacked against like pallets, in either of two orientations that are 180° apart.

Title: Copolyesters for high modulus fibers
Inventor: FLINT JOHN A
IPC: C08G63/189
Filed: 1991-12-03
Abstract: Polyester compositions comprising monomer units derived from 2,6-naphthalenedicarboxylic acid, 4,4'-bibenzoic acid and ethylene glycol are useful as fibers and molding resins when the ratio of 4,4'-bibenzoic acid to 2,6-naphthalenedicarboxylic acid is greater than 1:3. These compositions yield fiber with excellent tensile properties, both at room temperature and at elevated temperatures, when the two diacids are present in the composition in a mole ratio of about 60:40 to about 40:60, and especially when the two diacids are included in about equimolar amounts. When these compositions are melt spun at a relatively low melt temperature and high draw down ratio, fibers with excellent tensile properties are obtained without a subsequent drawing step.
