Patent CA-2188815-C (CA)
Title: Ultrafine cobalt metal powder, process for the production thereof and use of the cobalt metal powder and of cobalt carbonate
Inventor: HOHNE MATTHIAS
IPC: B22F9/24
Filed: 1996-10-24
Granted: 2005-05-24
Abstract: A method of preparing cobalt, metal powder, comprising: (a) reacting a soluble cobalt salt with a solution or suspension of an alkali metal carbonate or hydrogen carbonate, an alkaline earth metal carbonate or hydrogen carbonate, cobalt carbonate or hydrogen carbonate, or ammonium carbonate or hydrogen carbonate in a pH range of 5.5 to 6.8 and at a temperature below 35°C; (b) separating the cobalt carbonate precipitated product of step (a) and washing with water the separated cobalt carbonate precipitated product until the required purity is obtained and drying the washed cobalt carbonate; and (c) reducing the cobalt carbonate product of step (b) to cobalt metal powder. Prior art methods carried out at pH values in the range of from 7.0 to 7.4 result in the Co ions present in the solution being precipitated quantitatively. A disadvantage, however, is that there is a decline in the effectiveness with which the precipitate can be washed, which leads to the increased contents of Na, Ca and S in the end product. In contrast, the process according to the invention is carried out with the pH value being adjusted to less than 6.8. By this means a considerably more effective washing of the precipitate is achieved and hence the impurity content is definitely lowered.
Patent CA-2203220-C (CA)
Title: Electrical receptacle with safety shutter
Inventor: MEHTA PARAG J
IPC: H01R13/453
Filed: 1997-04-21
Granted: 2001-07-10
Abstract: An electrical receptacle of the type having movable shutter members positioned to prevent insertion of objects other than electric plugs through the plug blade-receiving openings into contact with line terminals.  Two identical shutter members, each having a camming portion and a blocking portion, are mutually assembled for relative, linear movement in either of two, opposite directions from a centered position to which they are biased by a pair of coil springs.  Rigid objects inserted through the receptacle openings contact an angularly disposed surface on the camming portion of the shutter members, causing lateral movement of the element.  When the blades of a plug are inserted, both shutter members move laterally to permit continued advance of the blades into the terminal contacts.  When a single object is inserted, the blocking portion of one shutter element prevents advance of the object.  A lip on the blocking portion prevents passage of the inserted object around the shutter element.  Other features include compatibility of the shutter structure with existing receptacles, including those with straight straps, a one-piece spacer supporting the shutter elements for low-friction movement and ease of automated assembly.

Inventor: CROMARTIE FRED A
IPC: B65H75/28
Filed: 1997-08-27
Granted: 2000-07-04
Abstract: An adapter is provided for rotatably supporting a tubular end of a yarn carrier in a take-up winding assembly of a yarn processing machine which accommodates the placement of a yarn transfer tail across an end surface of the yarn carrier between the yarn carrier and the adapter without breaking or cutting of the yarn transfer tail during winding of the yarn.  The adapter includes a hub portion for extending axially into the tubular end of the yarn carrier to center the yarn carrier on the adapter and which has an outside surface with a cross-sectional diameter less than the diameter of an adjacent inside surface of the yarn carrier for defining a space therebetween to accommodate the placement of the yarn tail.  An annular flange portion extends radially outwardly from the rear of the hub portion and has an inside surface for being positioned adjacent the end surface of the yarn carrier.  Members, preferably in the form of equally spaced ribs, are formed on the annular flange portion (1) for abutting the end surface of the yarn carrier to define a space between the end surface of the yarn carrier and the inside surface of the annular flange to accommodate the placement of the yarn tail and (2) for engaging and, preferably slightly penetrating, the end surface of the yarn carrier to retard relative rotation between the yarn carrier and the adapter.

Abstract: Cleaning compositions for ablation-type lithographic printing plates include solvent, non-solvent and lubricating components, the vapor pressures and concentrations of the various components being chosen such that the mixture never becomes too rich in solvent. In this way, the solvent's effect is directed primarily at thermal byproducts, which, because they are exposed and already partly decomposed, are more vulnerable to solvent action that the intact, anchored plate constituents in unimaged regions. The compositions are used in conjunction with mechanical rubbing of the plate surface following imaging.

Title: Method and system for identifying a feature on a longitudinally advancing member and marking the advancing member based on the identification
Inventor: FITZ JONATHAN G
IPC: G02B6/44
Filed: 2000-03-17
Granted: 2007-11-20
Abstract: A characteristic feature on a generally longitudinal member is detected as the member is longitudinally advanced on a path extending from a first position to a second position. Based on the detection of the feature on the member and monitoring of the advance of the member on the path, indicia can be applied to a desired position on the member. The detected feature can be an S-Z reversal existing or created on a strand of S-Z stranded optical fiber buffer tubes included in an optical fiber cable which is undergoing cable manufacture along a cabling line. Intensity data values representative of an optical image sample of the strand with the S-Z reversal feature, where the image sample is obtained by an optical radiation detector coupled to the path, are processed for identifying the S-Z reversal feature on the strand. Monitoring the advance of the cable to the marker allows for marking of the strand, or jacketing which has been applied to the strand, at a desired position during advance of the cable on the path.

Abstract: The present invention relates to an X-ray absorbing material which can be used in medicine as well as in the production of special protection clothes, protection screens, housings, protection coatings and isolation materials. In a first embodiment, the material uses as a filler a poly-dispersed kneading-segregated mixture containing metallic particles having a size of between 10 -9 and 10 -3 m, wherein said particles are bonded to the surface of a textile base. The density of the material is defined by the relation q N = (0.01 - 0.20)q P where q N is the density of the X-ray absorbing material as a whole while q P is the density of the material used for the particles of the X-ray absorbing filler. In a second embodiment, this invention uses as a filler the above-mentioned mixture though the particles are surrounded by the volume of a matrix made of a compound that solidifies under atmospheric pressure. The total mass of the poly-dispersed and segregated mixture is defined by the relation M = (0.05 - 0.5)m where M is the total mass of the X-ray absorbing poly-dispersed and segregated filler, while m is the equivalent mass of the filler material which is equal by its protection properties to the mass M. In a third embodiment, this invention uses as a filler the above-mentioned mixture though the particles are bonded to an intermediate substrate consisting of a textile base and surrounded by the volume of a matrix.
