Title: Method of increasing the yield strength of cold formed steel sections
Inventor: DALEY LEIGH BRIAN
IPC: C21D9/00
Filed: 1995-06-27
Abstract: Yield strength of a cold rolled steel section is increased and controlled by performing a predetermined amount of strain by way of cold working in an in-line roll forming process followed by a controlled amount of strain ageing wherein the temperature of the steel section is elevated to a point below 500 ~C and held at an elevated temperature for a time up to 30 seconds. The heating typically takes place by induction heaters (16) and the time ageing may be provided in an in-line galvanising bath (17) before cooling the steel in a quench bath (18). The effect is further enhanced by further cold working and the consequent additional strain in forming rolls (19). For a given steel composition the degree of yield enhancement can be controlled by the temperature and time parameters and also by the degree of initial roll forming in shaping rolls (10).

Patent CA-2197187-A1 (CA)
Inventor: RICKER RAINER
IPC: C11C3/10
Filed: 1995-08-12
Abstract: The extraction of native products is rendered difficult by the fact that attraction forces act between the liquid native products which are not water-soluble and the tissue incorporating them, and that other constituents are dissolved or present in the form of particles in suspension in the products during the extraction process. The initial substance mixture is, therefore, processed together with a water-soluble, organic solvent and optionally water to form a paste. The addition of the water-soluble, organic solvent enables the substance mixture to be separated cleanly into an aqueous phase and an organic phase in the centrifugal field, no further cleaning being necessary for the organic phase. The process according to the invention has a wide area of application.  In principle, it can be applied to all substance mixtures containing liquid, organic substances, in particular to vegetable and animal tissue. It is suitable for extracting oils from oleaginous fruit or waxes from wax-containing plants, as well as for extracting fish oils.
Patent CA-2197383-A1 (CA)
Title: Method and apparatus for providing print job buffering for a printer on a fast data path
Inventor: BENDER MICHAEL DONALD
IPC: G06F3/12
Filed: 1997-02-12
Abstract: An improved printer is provided that improves the response time before jobs are printer by providing a "fast data path" for certain print jobs while also storing on a hard disk all incoming print job data. This "fast data path" is especially useful in situations where the incoming print job lacks an "end of file" code, which couldotherwise hold up the processing of either this print job or later print jobs. Once the printer becomes relatively busy, and begins to accumulate a "queue" of print jobs waiting to be processed and printed, the printer will automatically store all of the print job data on the non-volatile memory (e.g., a hard disk) before that same data is sent to the processing circuitry. Since it is important to utilize the printer's capabilities efficiently, the printer can allow a "small" print job to be processed and printed after being received from one input port of the printer, while a much larger print job is still being accumulated from a second input port, even though the larger job began to be received first. Since all print job data received by the printer of the present invention is stored in a non-volatile memory, the capability exists for recovering such print jobs after the occurrence of a power failure. Upon power restoration, a "Header File" that contains status information about stored print jobs will be inspected, and if a print job was never completely printed, the printer will now begin printing the entire job. In this manner, the printer can guarantee that the entire job will be printed in one intact grouping of sheets of paper.

Title: An optical communications system having distributed intelligence
Inventor: JENNINGS MARK R
IPC: H04B10/08
Filed: 1997-03-19
Abstract: The invention is embodied in a distributed intelligence optical fiber communications system capable of fully automated and continuous monitoring and testing of the optical fibers and their connections within the optical fiber distribution frames therein. In particular, it is an optical communications system having an optical distribution frame including interconnection modules having actively intelligent microcontrollers thereon. Also, the distribution frame includes inventive electrical and optical interconnection fabrics between the distributed intelligence located on the interconnection modules and a host located outside of the distribution frame. The distributed intelligence interconnection modules allow monitoring, testing and/or related activities of the overall optical communications system to be performed locally at the interconnection modules. Also, when used in combination with the electrical and optical interconnection fabrics, the inventive modules substantially reduce optical fiber routing and enable more effective monitoring and testing operations to be performed, while maintaining compatibility with existing conventional cross-connect, switching and network architectures.

Abstract: Composition pour séparer le sérum ou le plasma, renfermant un oligomère cyclopentadiène, un agent gélifiant organique et un agent dispersant agissant sur cet agent gélifiant. L'agent gélifiant organique est un produit de la condensation du sorbitol avec un aldéhyde aromatique. L'agent dispersant est un copolymère-bloc polyoxyéthylène/polyoxypropylène, à rapport hydro-lipophile de 1,0 à 9,0. Cette composition permet de prévenir l'apparition de toute odeur nauséabonde imputable à une stérilisation sous rayonnement. Elle dissipe toute incidence du sérum ou du plasma sur les données d'analyse biochimique résultant de l'hémolyse, etc. Elle ne subit pas de séparation en phases de ses composants et conserve néanmoins une bonne aptitude à séparer le sérum ou le plasma. Elle présente une stabilité élevée au stockage, etc., comparable aux compositions classiques. En outre, cette composition se répand peu lorsqu'elle est appliquée et stockée et entraîne rarement un inversement de l'ordre de séparation au fil du temps.
