Patent CA-2133361-A1 (CA)
Inventor: COOKSEY EDWARD A
IPC: F04C18/356
Filed: 1994-09-30
Abstract: A rotary compressor including an orbiting piston is disposed within a cylinder bore.  A crankshaft with an eccentric causes the piston to orbit within the cylinder block.  Crescent shaped polymeric washers are interfit between the eccentric and cylinder bore endwalls to reduce friction and endplay therebetween.  Curved or whorled grooves on the face of the washer reduce frictional contact area and at the same time increase lubricant flow.  Compressor noise is reduced by the ability of the washers to act as resilient stops between the eccentric, crankshaft and cylinder endwalls.

Title: Method and apparatus for injection moulding
Inventor: SAYER MATTHEW E
IPC: B29C45/26
Filed: 1993-05-18
Abstract: The production of an injection moulding of plastics material comprises introducing a supply of plastics material through one or more openings in a mould space, and introducing by means of at least one gas supply passage a pressurised gas through a separate opening (44) in the mould space (13) into the plastics material filling the mould space whereby the gas creates a gas containing cavity (25) in the plastics material. Opening and closing of the gas supply passage (56) is controlled by a valve which is opened by the pressurised gas. The valve comprises a valve port (50) at the outlet end of the gas passage, and a movable valve member (31) extending longitudinally of the gas passage (56) for opening and closing the valve port (54). The valve member (31) at least when in its extended or valve port open position protrudes into the mould space and penetrates the plastics material thereby assisting the gas to enter the plastics material. Also with the valve member (31) in its withdrawn or valve port closed position plastics material is shut off from entering the end of the passage (56) from the mould space.

Title: System for accessing distributed data cache channel at each network node to pass requests and data
Inventor: PITTS WILLIAM M
IPC: G06F17/30
Filed: 1992-06-03
Abstract: Network Distributed Caches ("NDCs") (50) permit accessing a named dataset stored at an NDC server terminator site (22) in response to a request submitted to an NDC client terminator site (24) by a client workstation (42). In accessing the dataset, the NDCs (50) form an NDC data conduit (62) that provides an active virtual circuit ("AVC") from the NDC client site (24) through intermediate NDC sites (26B, 26A) to the NDC server site (22). Through the AVC provided by the conduit (62), the NDC sites (22, 26A and 26B) project an image of the requested portion of the named dataset into the NDC client site (24). The NDCs (50) maintain absolute consistency between the source dataset and its projections at all NDC client terminator sites (24, 204B and 206) at which client workstations access the dataset. Channels (116) in each NDC (50) accumulate profiling data from the re-quests to access the dataset for which they have been claimed. The NDCs (50) use the profile data stored in channels (116) to an-ticipate future requests.

Title: Method and kit for decorating surfaces with transfer patterns
Inventor: BARDEEN KEA
IPC: B41M1/40
Filed: 1995-01-16
Abstract: A method is provided for decorating an item's surface in order to display a design. The area to be decorated is first covered with a surface preparatory composition having a consistency that allows it to be spread onto the item's surface. A sheet with either a pre-printed or drawn pattern in an appropriate medium is then contacted with the preparatory layer for an amount of time sufficient to allow the pattern's medium to transfer onto the preparatory layer.The sheet is then removed from the preparatory layer after the pattern has been transferred, but before the preparatory layer has cured. Thus, the method may include a surface preparatory composition which is curable to form a stable layer which adheres to the item's surface. A step for curing the preparatory layer to fix the transferred pattern to the surface of the item may also be included. A kit is also provided which includes a surface preparatory composition and a pattern sheet. The pattern sheet contains a pattern made from a medium which can be transferred onto the surface preparatory composition. The kit may include a plurality of pattern sheets pre-printed with various patterns, and the solvent carrier may be water based.

Patent CA-2146644-A1 (CA)
Title: Method for the continuous preparation of methionine or methionine derivatives
Inventor: HASSEBERG HANS-ALBRECHT
IPC: C07C319/20
Filed: 1993-10-14
Abstract: The direct saponification of methionine nitrile obtained from methylmercaptopropionaldehyde, prussic acid and ammonia gives low yields, catalyst and educt losses and unwanted side-products.  The aim of the invention is therefore to provide a method which can be carried out without isolating the intermediate products, in particular continuously, and with low losses.  The ketone used is recovered in high yields after amide saponification since this liberates the ketone from side-products.  In order to recover the ammonia, it is necessary for the ammonia to be substantially freed of ketone, the mixture of ammonia, ketone and water obtained being separated under pressure in a separation column.  When the amide is saponified at ? 160°C, amide concentrations of less than 25% by wt. are preferred.  Methionine nitrile is produced by treatment with at least 4 equivalents of ? 50% by wt., ammonia at between 40 and 80°C for between 5 and 60 min. Cyanide residues are destroyed by heating to over 150°C. Methionine is of particular use as feedstuff, in particular in aqueous solution.

IPC: G01N21/79
Filed: 1994-09-15
Abstract: A method of quantitating proteins in complex samples using capillary electrophoresis can be used both to determine the concentration of a protein in a sample and to determine total protein concentration in the sample. In general, the method of determining the concentration of a marker protein comprises: (1) adding a known quantity of an internal standard compound to a sample containing at toast one protein, the internal standard compound selected from the group consisting of benzoic acid substituted with at least one halogen, producing a detector signal in relation to its concentration, and being capable of electrophoretic separation from the protein; (2) subjecting the sample and the internal standard compound to capillary electrophoresis to separate the protein and the internal standard compound from oath other and from other components in the sample; (3) measuring the detector signal produced by the internal standard compound and a detector signal produced by the protein to determine a ratio of protein signal to internal standard signal; and (4) determining the concentration of the protein in the sample from a standard curve of protein concentration versus the ratio of protein signal to internal standard signal. A typical protein measurable by the method is albumin. Typically, measurements are made at 214 em and the internal standard compound is 2,4-dichlorobenzoic acid
