Title: Banknote centering device for a validator
Inventor: BUKHMAN SERGEY
IPC: B65H9/10
Filed: 1998-04-24
Granted: 2003-04-01
Abstract: A banknote centering device uses a clutch arrangement to limit inward movement of side engaging plates used to center a banknote. The clutch also allows a fixed cycle motor to be used for both inward and outward movement of the side engaging numbers. The resistance of the banknote to buckling in the slot is sufficient to cause the clutch to slip. The device is rugged, easy to produce, and has proven very reliable.

Granted: 2005-10-18
Abstract: Conventionally, edible ice bodies are frozen in freezing moulds that are mov ed through a bath of cold salt brine, which ensures a good freezing effect, but also presents obvious problems. For avoiding these problems it has already been endeavoured to use cold air instead, but so far without noticeable practical success. The invention provides for an efficient and economical freezing by cold air, viz. in suggesting that the transverse carrier lamella plates (2) for rows of aluminium moulds (8) in an endless lamella conveyor are advanced stepwise into positions, in which cold air from underlying slot nozzles (46) is blown up into the spaces between the rows of moulds in a manner effectively shielded from the surroundings.

Patent CA-2265728-C (CA)
Title: Treatment of chlorine dioxide generator effluent and feed streams with fixed-resin bed
Inventor: PALEOLOGOU MICHAEL
IPC: C01B11/02
Filed: 1997-10-09
Granted: 2002-07-30
Abstract: A process employing a fixed-resin bed Acid Retardation Unit (ARU) to separate spent acid from chlorine dioxide generators into a de-acidified sodium sulfate component and a purified sulfuric acid component. The de-acidified sodium sulfate produced is returned to the chemical recovery cycle of the kraft mill in place of acidic chlorine dioxide generator effluent thereby avoiding the destruction of alkalinity in pulp mill liquors. In addition, sulfuric acid is purified providing an opportunity for reuse in various mill applications, and/or concentrated and recycled to the generator. Alternatively, to avoid high evaporation costs, the purified acid can be used to regenerate a cation-exchange unit (CEU) used in the conversion of sodium chlorate to a sodium chlorate/chloric acid mixture which is fed to the generator in place of sodium chlorate and sulfuric acid. Using this approach, the sulfuric acid requirement of chlorine dioxide generators and, in turn, the amount of acidic generator effluent can be reduced. The process is applicable to both atmospheric and subatmospheric chlorine dioxide generators. In the latter case, the concentration of the purified sulfuric acid from the ARU or any other acid separation system can be increased by using a portion of it to dissolve the sodium sesquisulfate by-product from such generators.

Granted: 2003-05-06
Abstract: A water heater is provided with a specially designed molded bottom pad/foam dam member which is placed in its bottom pan prior to placing bottom annular portions of the water heater tank and its outwardly spaced jacket structure into the bottom pan. The pad/dam member functions to automatically center the tank relative to its jacket structure, and to prevent leakage past the bottom pan of liquid foam insulation injected into the tank/jacket annulus after bottom end portions of the tank and jacket are secured within the bottom pan. The top side of the pad/dam member has three concentric annular grooves formed therein. The outermost first groove receives an annular bottom end portion of the jacket, while a second groove receives an annular bottom end portion of the tank. The provision of the third groove permits the same pad/dam member to be alternatively used with a water heater having a different tank diameter to thereby improve the manufacturing efficiency of a line of differently sized water heaters. When a second water heater having a different tank diameter is used with the bottom pad/foam dam member, annular bottom edge portions of the second water heater's jacket and tank portions are respectively received in the first and third top side grooves in the pad/dam member.

Abstract: An ankle support assembly (10) for use in combination with a soft-style snowboard boot (23). The assembly (10) includes a rigid heel cup (12) and a high back support (16) for supporting the calf region of the snowboard rider.   The high back support (16) includes an extension member (18) having a bottom end portion that is coupled within a pocket (14) formed in the upper rear region of the heel cup (12). The coupling permits the high back support (16) to float about a pivot axis that is translatable a predetermined amount along transverse, longitudinal and vertical axes of the ankle support assembly (10) so as to enable articulation of said ankle support device in a manner that closely approximates the articulation of the foot and ankle of the snowboard rider. A tether (20) is provided to prevent inadvertent decoupling of the high back support (16) from the heel cup (12). Also included is a length adjustable tension cable (22) to provide forward lean adjustment for the assembly (10).

Abstract: An improved plowshare is provided. Although it may be used in any submarine or terrestrial application requiring plowing or trenching, the improved plowshare is designed to be towed behind a cable-laying ship and to be used in underwater cable-burying operations to plow trenches in the ocean floor. The improved plowshare includes a downwardly-extending shank, a plurality of nozzles coupled to the shank, and a downwardly-swept protrusion for breaking up difficult soil and for controlling the depth of the shank in the soil as the trench is being plowed. The shank is rigid and capable of functioning as a passive plowshare, while the water jetting nozzles, which jet large volumes of water at a slightly forward angle relative to the perpendicular of the soil line, function as active trenching tools. The plowshare's use of both passive and active plowing technology allows it to be towed through the soil at a much lower drawbar force than traditional passive tools. Specifically, water from the nozzles fluidizes the soil in advance of the plowshare and creates a "swept volume flow" of fluidized soil that flows in a downward direction under and/or around the plowshare.  Fluidizing the soil in advance of the plowshare substantially reduces the drawbar force on the plowshare as it moves through the soil. To facilitate this flow of fluidized soil, the shank is aft-raked relative to the soil surface. Finally, the improved plowshare may be rotatable relative to the plow apparatus, thereby allowing it to function as a "rudder" for the plow apparatus.
