Patent CA-2059876-A1 (CA)
Title: Method of making longitudinally seam-welded tubing
Inventor: ZIEMEK GERHARD
IPC: B23K26/00
Filed: 1992-01-23
Abstract: ABSTRACT OF THE DISCLOSURE     The welding zone of a split tube is cleaned by grease removal using flash heating just ahead of welding in order to evaporate any grease in the zone to be welded.The flash heating can be provided by the heat conduction away from the welding beam if the latter is a laser beam. Alternatively a welding arc or the like can be preceded by a laser beam that just evaporates the grease on the strip metal without welding it.
Patent CA-2062444-A1 (CA)
Title: Turbine exhaust arrangement for improved efficiency
Inventor: SILVESTRI GEORGE J JR
IPC: F01D3/02
Filed: 1992-03-06
Abstract: Steam exhaust outlets of a low pressure steam turbine are fitted with a divider plate to separate exhaust steam into isolated flow paths in fluid communication with a condenser. Separation of the flow paths is maintained through the condenser so that heat rate is improved by lower average back pressure and higher temperature condensate exiting the condenser. In a double flow turbine, a further divider plate separates steam from one exhaust outlet from that of the other exhaust outlet thereby creating four steam flow paths to the condenser.

IPC: D21F5/04
Filed: 1990-07-19
Abstract: A method and a machine are described for drying of fibrous web, especially suitable for high speed machines producing printing papers. High drying rates are obtained by subsequently pressing the two surfaces of wet web (5) onto two large diameter dryer cylinders (1, 2) heated to between 100 and 150°C. In the first nip, the web (5) is pressed on the dryer cylinder (1) by a felted press roll (3), while an unfelted smooth roll (4) is used to press the web (5) on the second dryer (2). Drying rates obtained when practicing the invention are substantially greater than those found in conventional dryer sections. The product obtained according to this method is 30 % stronger than the conventionally dried uncalendered paper, and without calendering has a smoothness and gloss similar to those of calendered conventional papers.

Title: Optical traffic preemption detector circuitry
Inventor: HAMER STEVEN M
IPC: G08G1/087
Filed: 1992-06-01
Abstract: An optical traffic preemption detector according to Figure 6 detects pulses of light emitted by an approaching emergency vehicle and provides an output signal which is processed by a phase selector. The phase selector can request a traffic signal controller to preempt a normal traffic signal sequence to give priority to the emergency vehicle. A detector assembly is mounted in proximity to an intersection and can have multiple detector channels. A detector channel can have multiple photocells. each photocell is provided with a rise time filter. If a detector channel has more than one photocell, the outputs of the respective rise time filters are coupled together. An output of a rise time filter, or coupled rise tame filters, is first applied to a current-to-voltage converter and then a band pass filter. The band pass filter isolates a decaying sinusoid signal from a signal representative of a pulse of light. The decaying sinusoid signal is processed to produce a detector channel output signal that has a number of pulses for each pulse of light.

Title: High temperature oil-resistant elastomers
Inventor: ABRAHAM TONSON
IPC: C08C19/02
Filed: 1990-12-13
Abstract: High-temperature oil-resistant elastomers are prepared from butadiene alkenylpyridine copolymers, butadiene-acrylate copolymers, and copolymers of butadiene with 1,3-dienes containing fluorine.  The unsaturated olefinic backbone and pendant unsaturation derived from the hydrocarbon diene of each of the copolymers is hydrogenated to a high degree by a catalyst which improves the heat resistance of the copolymer without hydrogenation of the polar groups thereof which would lower the oil-resistance of the copolymer. A  complexing agent for the hydrogenation catalyst prevents poisoning of the catalyst by the polar groups of the copolymers thereby enabling the catalyst to complex with unsaturated sites along the olefinic copolymer backbone to achieve high levels of hydrogenation thereof.

IPC: B61D17/00
Filed: 1993-01-08
Abstract: SUMMARY:   In this method for the integral manufacture of coach bodies, U-shaped channels (10) for the feed and removal of air, illumination and apparatuses in a corner region (9) as well as shape-determining insulation bodies (12) in the corner regions (11) are glued to an inner covering layer (8) shaped and carried by a winding mandrel.  A not illustrated build-up analogous to the corner region (9) is provided in a base region (13). For the absorption of bending stresses and longitudinal forces, a stiffening framework (14) and corner profiles  (15;  16)  are provided, which are glued together with the composite body manufactured  in the preceding method steps.   In a further method step, insulation plates are glued into the rectangular openings of the stiffening framework (14) and blank covers are laid into the openings of the later windows and doors.   Thereby,  a step-free surface arises again, which is capable of being wound over and which is wound over by an outer covering layer.  The coach body manufactured in the preceding method steps is removed from the shape-determining winding mandrel.   The blank covers cutting out the windows and doors are then severed out.  Bores for the feed and removal of air as well as openings for illumination bodies are applied in the ceiling.   (Figure 3)

Filed: 1993-04-08
Abstract: A FUZZY LOGIC CONTROL METHOD FOR REDUCING WATER CONSUMPTION IN A MACHINE FOR WASHING ARTICLES                 Abstract of the Disclosure A fuzzy logic based control method reduces the amount of water used by a washing machine or dishwasher during a cycle.  A sensor detects when the washer has adequate water by monitoring the behavior of the washer pump motor as fresh water is coming in. There is a characteristic oscillation of the magnitude of the motor current as the pump cavitates during this operation, which diminishes when the washer is properly filled. By using fuzzy logic to sense this point of diminished or ceased cavitation and shutting off the incoming water, substantial savings of water can be achieved.
