Abstract: An automated pipeline rehabilitation apparatus (10) is disclosed. The apparatus employs a centering assembly (24) with pivoting arms (26, 28) which can pivot between an operating position and a installation/removal position to allow the unit to be removed from a pipeline. Arcuate rings (38, 40) are mounted on the arms. Spray nozzles (44) are mounted on the arcuate rings for reciprocating arcuate motion along the rings to treat the pipeline.      The nozzles (44) can be used to clean the pipeline and prepare the outer surface of the pipeline with high pressure water jets with entrained abrasives. The nozzles (44) can also be used to apply a coating, preferably a polyurethane coating to the pipeline. A nozzle assembly (200) can be used to mount a spray gun (204) on the apparatus. The nozzle assembly permits easy adjustment of the nozzle position in two different directions to insure a consistent spray pattern. The nozzle assembly also provides for reversal of the tip of the nozzle for cleaning.

Title: Method for minimizing the switching loss in a power switch
Inventor: WEINBERG ALAN
IPC: H03K17/0814
Filed: 1992-01-16
Granted: 2001-10-23
Abstract: A switching current converter is connected in parallel with each controlled power switch in an electric cir-cuit so that it is allowed to operate from the input voltage and transfer energy from input to output dur-ing the turn-on periods of the controlled power switch, whereby each power switch is allowed to be turned ON when a near-to-zero voltage is present across it. The switching converter serves as an active power switch stress relieving means, resulting in minimizing the switching loss in the power switch while providing the energy for operation of the power switch in a very efficient way.
Patent CA-2066329-C (CA)
Title: Microbial monitoring device
Inventor: SAPITOWICZ ROBERT
IPC: C12Q1/04
Filed: 1992-04-16
Granted: 2000-06-20
Abstract: This invention presents methods for detection and evaluation of metabolic activity of microorganisms based upon their ability to consume dissolved oxygen.      The methods utilize a fluorescence detection system which makes use of the sensitivity of the fluorescent emission of certain compounds to the presence of oxygen, which quenches (diminishes) the compound's fluorescent emission in a concentration dependent manner. Respiring microorganisms will affect the oxygen concentration of a liquid medium in which they are immersed. Thus, this invention provides a convenient system to gather information on the presence, identification and metabolic activity of microorganisms by determining their effect on the oxygen concentration of the media in which they are present.

Title: Four-cycle engine
Inventor: TAMBA SHINICHI
IPC: F02F1/32
Filed: 1993-04-19
Granted: 1998-05-05
Abstract: There is disclosed a four-cycle engine in which a crankshaft and a cam shaft are disposed generally parallel to each other, and an intake port and an exhaust port are formed in a cylinder head.  The intake port and the exhaust port are arranged in such a manner that a line passing through the centers of the intake port and the exhaust port is non-parallel to the axis of the crankshaft.  With this arrangement, an intake passage and an exhaust passage can be greatly shortened, and therefore an intake efficiency as well as an exhaust efficiency can be enhanced, thereby enhancing the performance of the engine.  In an air-cooled engine, the overheating of the engine is greatly restrained.

Abstract: A fire door release mechanism includes a pair of levers engaging a bearing disc to hold a toothed clutch in engagement between a shaft of the fire door and a shaft of its operator.  One of the levers has, at its end remote from the bearing disc,  a pin on which a holding block is pivotally mounted.  The other lever also has a pin at its remote end which is retained within a pocket on the holding block so long as tension is applied to the block, which tension is normally provided by a fuse link chain.   When the tension is released, the levers, which are lightly spring biased, pivot out of engagement with the bearing disc to allow the clutch to disengage and separate the operator shaft from the fire door shaft.
Patent CA-2100603-C (CA)
Title: Liquid level monitor
Inventor: MATTIS DONALD J
IPC: G01F23/28
Filed: 1993-07-15
Granted: 2002-11-19
Abstract: A liquid level monitor for sensing the level of liquid in a tank or vessel, typically an automobile radiator, employing a probe with a light emitting diode and phototransistor mounted inside an enclosure, the enclosure having a transparent lens through which light can pass, and the lens having a prism configuration which diffuses or alters stray light which occurs by reflection off an interior core wall of the vessel and prevents the diffused or dispersed light from rendering the phototran-sistor conductive and possibly leading to a false indi-cation or reading of liquid level. The light emitting diode is electrically excited with a high-intensity, short duration pulse, which improves the sensitivity of the monitor. The advantage of the present construction is that there are eliminated erroneous readings result-ing from stray light reflections off internal structures in the tank.

Title: Method of manufacturing a lined moulded part
Inventor: NICOLAY ALBERT
IPC: B29C51/32
Filed: 1995-06-06
Granted: 2003-08-12
Abstract: Described is a method of manufacturing a lined moulded part, preferably a moulded part for internal trimming of a vehicle.  Such moulded parts comprise a dimensionally stable carrier portion and, connected therewith on the visible side a lining of film, textiles or similar decorative lining material.          According to the method, heated blanks of fibrous materials containing binders are shaped to form a carrier portion in a cold tool, and simultaneously connected with the lining.  In a first process step, the lining material is inserted with an overhang relative to the contour of the carrier portion into a multi-function tool, and clamped and secured peripherally along the contour of the carrier portion.          Thereafter the heated material of the carrier portion is inserted into the multi-function tool and shaped by closing the tool and connected in the region of the surface of the moulded portion with the lining material, an overhang of the carrier portion material being separated by shearing along the edge of the carrier portion.  In a third process step, the overhang of the lining is finally trimmed peripherally by a trimming knife.  Thereafter the multi-function tool is opened and the lined carrier portion is removed, whereupon the overhang of lining may be bent over about the edge of the moulded part.
