Patent CA-2082445-A1 (CA)
Inventor: NOHR RONALD S
IPC: C09J7/50
Filed: 1992-11-09
Abstract: Abstract A method of forming substantially continuous filaments having delayed wettability, in that the filaments are not wettable by water upon their formation but become wettable within from about three hours to about 30 days thereafter without any post-formation treatment, which method involves the steps of (1) ? melting a mixture consisting of a thermoplastic polyolefin, an additive, and a retardant coadditive; (2) extruding the resulting molten mixture through a die (3) contacting the filaments with a quenching fluid; (4) entraining and drawing the filaments in a nozzle with an attenuating liquid having a defined linear speed; and (5) collecting the drawn filaments. The additive is a defined polysiloxane polyether which is present in an amount of from about 1.8 to about 3.0 percent by weight, based on the amount of thermoplastic polyolefin. The retardant coadditive is a high surface area particulate inorganic or organic material which is capable of being at least partially coated by the additive. The filaments canbe collected as tow or can form the basis of a nonwoven web which is charac-terized by minimal filament-to-filament fusion bonding. The preferred thermo-plastic polymers are polyolefins, with the most preferred polyolefin being polypropylene.

Abstract: An upper control arm for a vehicle suspension system having a modulus section of hollow construction for reduced weight.  The modulus section of the control arm is of a stamped and welded construction thereby eliminating material weight while reducing the cost of manufacturing.  The modulus section has a substantially triangular configuration with a reinforced rim flange along the high compression stress area of the control arm elbow.   The reinforced rim flange improves the strength of the control arm without sacrificing the weight reduction provided by the hollow construction.

Title: Door Accessory with a Hydraulic Retarding Device
Inventor: LEE SIMPSON
IPC: E05F3/20
Filed: 1993-06-16
Abstract: A door accessory, such as a door hinge, includes a hydraulic retarding device for cushioning the closing action of a door.  The hydraulic retarding device has a cylinder body which confines a fluid receiving space to receive hydraulic fluid therein.  One end of a piston rod extends into the fluid receiving space and has a valve unit provided thereon.  The valve unit includes a piston which is formed with perforations and which forms a clearance with the cylinder body and a valve ring which is loosely sleeved on the piston rod. The piston rod is operably associated with the door movement so that the valve ring does not block the perforations on the piston during a door opening action, thereby permitting faster fluid flow inside the fluid receiving space and providing little or no resistance to the movement of the piston rod, and so that the valve ring blocks the perforations on the piston during a door closing action, thereby permitting fluid to flow only through the clearance so as to retard the movement of the piston rod.

Title: Recompilation of Computer Programs for Enhanced Optimization
Inventor: GILLIES DAVID M
IPC: G06F9/45
Filed: 1993-10-29
Abstract: An optimising compiler for producing executable programs from code, high level languages compiles the code whilst generating data from which a callgraph may be constructed,  and then recompiles the procedures identified in the callgraph in an order which reverses the topology of the callgraph while monitoring usage of hardware registers.  Procedures which are rarely or never called,  or result in termination of the program, are identified, and are modified if needed so that if called, registers which they may modify are saved prior to execution of  the procedure  and  subsequently restored  if necessary,  so  that  in  a  calling procedure,  subsequently recompiled, no account need be taken of possible register usage  by  the  called  procedure.    This  makes  additional registers available to the calling procedure,  and enables register  storing  and  restoring  which  must  otherwise  be associated with the callsite to be eliminated.

Title: Procedure for making copies from photographic originals
Inventor: KRAFT WALTER
IPC: G03B27/73
Filed: 1993-09-09
Abstract: In accordance with the present invention, these and other concomitant problems are solved. The present invention relates to a process for making copies of photographic originals in a photographic copying machine, comprising the steps of sectionally scanning the original being copied by a measurement system in a measurement station of the photographic color copying machine, feeding measured light that is transmitted or remitted from each scanned section of the original being copied to a detector configuration, converting the measured light into electrical signals as a function of wavelength and intensity of the measured light, digitizing the electrical signals to obtain color data for processing in a computation and evaluation unit, and analyzing the color data in an analysis unit to establish correction values. The step of analyzing further includes steps of (a) subjecting the color data to a reversible linear or non-linear standardization transformation that is order or film type specific, (b) converting the color data into normalized color values to provide initial data for the analysis unit, (c) forming film specific normalized correction values in the analysis unit from the normalized color values, taking into account color, density, and structural characteristics of the original being copied, and (d) converting the film specific is normalized correction values of the analysis unit into de-standardized correction values in a de-standardization unit that is attached to the analysis unit using a de-standardization transformation which is inverse to the standardization transformation, the de-standardized correction values also taking into account the color characteristics of the film material being copied. A  required amount of copying light is determined from the de-standardized correction values in an exposure calculation unit, and copies are made from the original being copied in an exposure station based on said copying light.
