Patent CA-2222139-A1 (CA)
Inventor: SAVU PATRICIA M
IPC: C04B41/48
Filed: 1996-05-03
Abstract: The present invention provides a water-soluble and shelf-stable aqueous fluorochemical polymeric treatment useful to treat porous substrates to render them repellent to water- and oil-based stains. The treatment comprises a water-soluble fluorochemical polymer containing only carbon atoms in the backbone, with a plurality of each of the following groups pendent from the backbone:  (a) fluoroaliphatic groups, (b) carboxyl-containing groups, (c) oxyalkylene or polyoxyalkylene groups, and, optionally, (d) silyl groups. Typically, the treatment polymers have interpolymerized units derived from one or more, and preferably a plurality, of each of the following monomers: (a) monomer selected from the group consisting of acrylate, methacrylate, acrylamide, methacrylamide, thioacrylate or meththioacrylate compounds containing a fluoroaliphatic moiety that is linked to the residue of the compound through a divalent, organic linking group; (b) monomer selected from the group consisting of acrylic acid, methacrylic acid, carboxyalkylacrylate and carboxyalkylmethacrylate compounds; and (c) monomer selected from the group consisting of acrylate, methacrylate, acrylamide, methacrylamide, thioacrylate or meththioacrylate compounds containing an oxyalkylene or polyoxyalkylene group linked to the residue of the compound through an oxygen, sulfur or nitrogen atom. Preferably, the polymer further includes interpolymerized units derived from monomers selected from the group consisting of acrylate, methacrylate, acrylamide, methacrylamide, thioacrylate and meththioacrylate compounds that contain an alkoxysilane moiety linked to the residue of the monomer through a divalent organic group. In another aspect, the present invention provides shelf-stable aqueous solutions or dispersions comprising the polymeric treatment and a method of treating porous substrates to render them repellent to water- and oil-based stains using the aforementioned polymeric product. Because the water-soluble polymeric treatment of the present invention, and the shelf-stable aqueous solutions thereof, can be applied to porous substrates in aqueous solution, they eliminate the need for environmentally harmful and toxic co-solvents. Particularly when applied to masonry and other siliceous materials, these polymeric treatments can react with the substrate onto which they are applied to form an invisible and water-insoluble coating that repels both water and oil, resists soiling, and that cannot be easily washed from the surface of the substrate. Substrates treated with these polymers are thereby durably protected from rain and normal weathering.

Patent CA-2245876-A1 (CA)
Inventor: BAECKLUND KENNETH LARS
IPC: G01L5/06
Filed: 1997-02-18
Abstract: Device for measuring tension force in web alt. wire without giving any permanent affect on the measured object (7). In goods transportation it is common to use webs to tie down (lash) the load to the load carrier. Then it is important that right pretension force is applied to achieve a safe transport.  The aim is to be able to check this force before but even during the transport. This wish is solved with a hand carried device that can be moved across the measured object (7) from the side, perform the measurement after activation arm has been pulled and be removed after deactivation without having any remaining affect on the lashing. Technically this is done when the activation forces the object (7) to bend over a number of rolls (17, 18). This bending calls for a force perpendicularly to the web/wire (7) that is registered, recalculated (calibrated) and displayed as the searched force in the object. To achieve high accuracy the instrument is equipped with two widthsetters which correct set allows exact positioning sidewise of the measured object and a device that can be adjusted and compensates the force for the free length of the object (7). Besides the instrument has an automatic power control which alarms when the battery must be changed.

Title: Asynchronous data pipe for automatically managing asynchronous data transfers between an application and a bus structure
Inventor: SMYERS SCOTT D
IPC: G06F13/12
Filed: 1997-02-19
Abstract: An asynchronous data pipe (ADP) automatically generates transactions necessary to complete asynchronous data transfer operations for an application over a bus structure. The ADP includes a register file which is programmed and initiated by the application.  The register file includes the bus speed, transaction label, transaction code, destination node identifier, destination offset address, length of each data packet, packet counter, packet counter bump field, control field, and a status field. During a data transfer operation, the ADP generates the transactions necessary to complete the operation over the appropriate range of addresses, using the information in the register file as a template. The ADP increments the value in the destination offset address field for each transaction according to the length of each data packet, unless the incrementing feature has been disabled and the transactions are to take place at a fixed address. The packet counter represents the number of transactions remaining to be generated. The packet counter value is decremented after each packet of data is transferred. The application can increment the packet counter value by writing to the packet counter bump field. A multiplexer is included within a system having multiple ADPs for multiplexing the information from the ADPs onto the bus structure. A demultiplexer is included within a system having multiple ADPs for routing information from the bus structure to the appropriate ADP.

IPC: G01M15/10
Filed: 1997-07-15
Abstract: A method of testing the assembled state of an internal combustion engine and quickly and accurately judging whether there is at least one fault with the assembling of the engine. While an exhaust-valve side space (100) is closed and a crank shaft (18) is rotated at a constant speed, the pressure in the exhaust-valve side space and the pressure in a surge tank (96) are detected by pressure sensors (106, 98), respectively. The assembled state of an engine (90) is tested based on the predetermined conditions of the detected two pressures. Those predetermined conditions may be the crank-shaft angles when the two pressures take respective maximal values, the crank-shaft angles when the two pressures change from their constant states to their increasing or decreasing states, etc. Based on those values, incorrect phases of crank and cam pulleys, incorrect clearances of intake and exhaust valves, missing of a compression ring, etc., can be identified.
