Patent CA-2064578-A1 (CA)
Title: Optical scanner
Inventor: CHU CHING
IPC: G02B26/10
Filed: 1990-08-02
Abstract: An optical scanner has a light distributor (26) rotating about an axis (32) spaced from but parallel to the optical axis of a light source (106). Lenses (94) are mounted on a carrier that rotates about the optical axis. The distributor and carrier rotate at the same angular velocity and are arranged so that the lens (94) and associated distributor (26) move across the media at the same time. By rotating the lens about the optical axis, the scanning beam remains in the central zone of the lens as it passes across the media.

Title: Headgear-mounted indicator for ionizing radiation
Inventor: CROWSON ROBERT H
IPC: G01T7/00
Filed: 1990-08-29
Abstract: A visual display (21) for indicating a level of ionizing radiation is mounted on a portion of an item of headwear, such as safety goggles (10), at a position within the peripheral field of vision of a wearer. Such a display (21) advises a wearer of a level of radiation, including warning levels, in real time without requiring activity on the part of the wearer. In one embodiment, an ionizing radiation detector (31), accompanying circuitry (19), and the visual display (21) are mounted on the glasses (10), such as on the frame (13). In another embodiment, a commercially-available detector (31a) is used to provide an output from a location remote from the headwear to actuate the visual display on the headwear. Various circuit embodiments are also disclosed.

Title: Controlled cooling system for a turbocharged internal combustion engine
Inventor: MCTAGGART LESTER E
IPC: F02B29/04
Filed: 1992-10-16
Abstract: CONTROLLED COOLING SYSTEM FOR A TURBOCHARGED INTERNAL COMBINATION ENGINE                 ABSTRACT OF THE DISCLOSURE      A controlled cooling system for a turbocharged internal combustion engine having a heat exchange radiator, liquid coolant to absorb heat from the engine, a pump to circulate coolant through the system, a fan to force air in heat exchange with the engine coolant radiator and a radiator for the charge-air after cooler coolant.  The cooling and turbocharge system includes a temperature control valve to direct a portion of the liquid coolant discharged from the engine to the radiator and to direct a portion of the liquid coolant to bypass the radiator in response to the temperature of the liquid coolant after discharge from the engine. A liquid subcooler heat exchanger lowers the temperature of the liquid coolant by passing the coolant in heat exchange with forced air from the fan.  A flow control valve directs a portion of the liquid coolant discharged from the radiator to the subcooler heat exchanger and the remainder of the liquid coolant to the engine. An aftercooler heat exchanger lowers the temperature of the combustion air discharged from the turbocompressor by passing the combustion air charge in heat exchange with the liquid coolant from the subcooler heat exchanger.  Means are provided to control temperature of the combustion air charge to prevent overcooling. A fan speed controller adjusts the speed of the fan in response to ambient air temperature and in response to load on the engine. Radiator and subcooler heat exchangers are arranged in series flow with successive reductions in coolant flow to permit maximum liquid coolant temperature change compatible with available ambient air temperature and operating power level.

Title: Tube weld seam inspection device
Inventor: TOBAR RONALD A
IPC: G01N21/952

Abstract: TUBE WELD SEAM INSPECTION DEVICE                 Abstract of the Disclosure The invention provides a method and apparatus for on-line, real-time imaging and inspecting a seam weld on a moving tube in a conventional tube forming environment.  The apparatus is in a compact container sealed from workplace contaminants.  A planar light source directs a steady plane of light by using mirrors, through an aperture in the container and onto the tube seam at a 45° angle relative to the tube axis, forming a light pattern on the moving tube.  A camera in the container images the light, again at 45° relative to the tube axis, and said image is displayed remotely on a conventional video monitor.  An operator interprets the light pattern image and adjusts the tube forming apparatus accordingly.

Title: Uncoated woven fabric and method of manufacturing same
Inventor: NAKAYAMA YOSHIKAZU
IPC: D03D1/02
Filed: 1992-12-02
Abstract: ABSTRACT OF THE DISCLOSURE     A woven fabric is wove using warps (6) and wefts (7) having coated threads (6a) and (7a), respectively, every other thread, with the remaining threads being uncoated threads (6b),  (6c).  The coated threads (6a), (7a) are melted by a heat setting treatment, thereby fusing the coated threads (6a) in the warps (6) to the wefts (7) and the coated threads (7a) in the wefts (7) to the warps (6).  The woven fabric becomes an uncoated woven fabric on which a thin coating film has not been formed.  Accordingly, the uncoated woven fabric has a predetermined amount of air-permeability.  The threads will not become frayed or tattered and the amount of air permeability will not change even when the uncoated woven fabric is cut.

Title: Production of cellulose pulp bleaching chemicals
Inventor: HENRICSON KAJ
IPC: C01B15/023
Filed: 1993-06-09
Abstract: ABSTRACT            Hydrogen peroxide for cellulose pulp bleaching is pro-duced directly at a pulp mill without electrolysis. Hy-drogen is produced from black liquor from the pulp mill pulping process, and that hydrogen is then reacted (e.g. with oxygen and anthraquinone) to produce hydrogen perox-ide, which is in turn used to bleach pulp in a P stage directly on site. The hydrogen is produced from the black liquor by heat treatment to produce an off-gas containing DMS,  and other hydrocarbons.  Hydrogen can be produced from the off gas in a number of ways, including by react-ing it with a melt in a recovery boiler, or ash from a recovery boiler.
