Patent CA-2143753-A1 (CA)
Title: Housed bearing assembly with sealed roller
Inventor: IDE RUSSEL D
IPC: F16C13/02
Filed: 1993-10-14
Abstract: A housed bearing assembly suitable for use as a pil-low block bearing unit or flanged bearing unit. The assem-bly includes a shaft sleeve (21) and roller body (23) secured to one another and enclosed by a housing (10). The roller body (23) is adapted to rool against an inner peripheral sur-face of the housing (10). A supply of lubricant sufficient to lubricate the roller body (23) is contained within the hous-ing. The housing (10) and rolling body (23) are designed to direct lubricant toward fluid tight areas of the assembly and away from those areas where leakage might occur. A lubri-cant containment reservoir is formed in either the housing or the shaft such that lubricant will not reach the space or interface betwen the shaft and the housing. The roller body may be provided with a drip edge to further direct lubricant away from the interface between the housing and the shaft. The housing is constructed as a spherical segment seated in a spherical seat to allow pivoting of the inner housing por-tion to pivot to adjust for misalignement.

Title: Object-oriented graphic picking system
Inventor: PETERSON JOHN
IPC: G06F3/0487
Filed: 1994-01-03
Abstract: A method and apparatus for defining customizable pick, hit or find detection criteria for geometric types and using the results of the search as a basis for determining whether to perform an action. According to the inventive method, a search protocol is defined for geometric types. The search criteria is compared with graphic objects to determine whether the object matches the criteria. Based on the results of the comparison, an output is produced. In addition to allowing customized hit criteria for primitive geometric types, the hit object framework allows hit criteria to be specified for geometric types created by the application developer.

Patent CA-2147462-A1 (CA)
Title: System for Detecting Ice on Metal Surface
Inventor: STERN HOWARD
IPC: G08B19/02
Filed: 1993-10-20
Abstract: For detecting the presence of a substance such as ice or snow on a surface such as the wing of an aircraft, light is emitted from an unpolarized source (13). The unpolarized light passes through a linear polarizer (11) which has a vertical polarization axis. The vertically polarized light passes through a quarter wave retarder plate (12), which changes the linearly polarized light into circularly polarized light. The quarter wave retarder plate (12) has its slow and fast axes both at 45 degrees relative to the vertical axis of the linear polarizer (11). A specular surface (14) reflects the incident circularly polarized light back along path (23). If surface (14) is ice-free, the reflected light will result in an image viewed by the eye (26) alternating between dark and bright, respectively. Any ice or snow covering a portion of surface (14) will cause that portion of the image to maintain the same brightness.

Title: Process for producing aromatic amines
Inventor: LANGER REINHARD
IPC: C07C209/36
Filed: 1995-08-07
Abstract: Aromatic amines are produced by hydrogenation of the associated aromatic nitro compounds in the gas phase over fixed catalysts. The catalysts contain active hydrogenation metals on supports. The reaction is conducted at a pressure of 2-50 bar and at a temperature in the range 250-500°C under adiabatic conditions. A circulating gas is passed over the catalyst, which circulating gas contains 3-150 moles of hydrogen, 2-100 moles of the amino groups to be formed per mole of nitro groups, and 2 to 6 moles of water per amino group equivalent. The amine and water formed,, as well as a purification stream, are separated from the circulating gas. Thereafter the circulating gas is enriched with volatilised aromatic nitro compound and fresh hydrogen and recycled.

Patent CA-2169310-A1 (CA)
Title: Method for controlling engine timing
Inventor: HOUTZ PHILLIP J
IPC: F01P7/16
Filed: 1996-02-12
Abstract: A method for an internal combustion engine controls engine timing as a function of engine load, speed and air intake temperature to reduce engine NOx emissions and/or engine fuel consumption.  The method is particularly beneficial to a large, aftercooled turbocharged engine which utilizes a cooling system having a liquid cooled, separate circuit aftercooler (SCAC) to cool the pressurized intake air.  By routing the aftercooler circuit and engine coolant circuit through a common or single core radiator, the aftercooler cooling circuit temperature and associated engine air intake temperature are reduced to further reduce engine NOx emissions and/or engine fuel consumption.

Title: Internal rotary tube cutter
Inventor: SCHARTINGER EDWARD J
IPC: B23D21/08
Filed: 1996-12-16
Abstract: A tube cutter designed for cutting a pipe where access is limited to the interior of the tube only. A rotatable cutter head mounted at the end of an elongated drive shaft carries a plurality of cuffing wheels. The tube cutter is inserted into a tube to be cut from one end thereof using the elongated drive shaft to position the cutter head in the tube. When the cutter head is inserted into the predetermined location, a feed drive is energized which rotates a scroll head to cause the cutting wheels to move in a radial direction to advance and engage the interior surface of the tube in a concentric manner undergoing cutting. When the tube has been severed, the feed drive rotation is reversed to retract the cutting wheels into the rotatable head, so as to enable removal of the rotary tube cutter from the tube.

Title: Plant genes affecting gibberellic acid biosynthesis
Inventor: BRIGGS STEPHEN P
IPC: C12N15/60
Filed: 1995-06-15
Abstract: Genes controllong gibberellic biosynthesis are used in genetic engineering to alter plant development. Alterations in the nature or quantity of products of the genes affects plant development. A family of An genes in monocots encodes a cyclase involved in the early steps of gibberellic acid (GA) biosynthesis. Members of the family are identified in wheat, barley, sorghum and maize. Two members of the family, the genes An1 and An2, are identified in maize. The An1 gene is cloned and the function of the gene is characterized. An2 is isolated and identified by homology to An1. Using recombinant genetic technology, GA levels are manipulated. Changes in GA levels alter monocot plant phenotypes, for example, increasing or decreasing height and fertility.
