Patent CA-2228200-A1 (CA)
Inventor: HEIMANN BRUNO
IPC: E03C1/06
Filed: 1998-01-27
Abstract: In order to improve a wall-mounted bar for a hand-held shower or the like, which is in the form of a tube and mounted on a structural wall by a plurality of brackets that are so configured that the rod for the wall bar can also be secured by the attachments screws for the brackets, it is proposed that each of the brackets incorporate a supporting body that in its turn incorporates an opening to accommodate the tube of the wall bar; a bore for the attachment screw being of greater diameter in the area of this opening than the head of the screw and subsequently stepped down to the approximate diameter of the screw shaft, and the wall-rod tube incorporating a radial bore so that the wall-bar tube can be fixed on a supporting body with an attachment screw, whereas the other supporting bodies hold the wall-bar tube with the opening alone, or the wall-bar tube is provided with at least one radial bore that is of greater diameter than the head of the screw, so that the wall-bar tube can be fixed on the supporting body only by using a washer, which is of greater outside diameter, with the attachment screw, whereas the other supporting bodies hold the wall-bar tube by the opening alone.

Inventor: MCCARTHY CHRISTOPHER E
IPC: B04C5/28
Filed: 1996-06-20
Abstract: Hydrocyclone cleaning systems and methods remove contaminants from a suspension of papermaking stock. A subsystem (10) employs forward cleaners for removing heavy contaminants while a subsystem (12) is fed directly from subsystem (10) and removes lightweight contaminants. The subsystem (12) also includes a through-flow cleaner which receives the rejects flow from a primary reverse flow cleaner and both systems are connected to a common surge tank arrangement (15). Both subsystems operate at low consistencies or high efficiency while the primary through-flow cleaner of subsystem (12) provides a system output having a consistency approximately twice as high as that of the input so that the overall operation operates both as a stock cleaner and a stock thickener.

Abstract: A method of separating oil, water and sand in a production fluid. The production fluid is fed through a downhole liquid/liquid hydrocyclone (9). An oil enriched stream from the hydrocyclone (9) is pumped to the surface, while an oil depleted stream is fed to a downhole solid/liquid hydrocyclone (12). Here, the bulk of the solids are separated from the water, so that water which is substantially free of solids can be transported to a downhole disposal site (14).

Title: Jointing system for wall-building pieces
Inventor: MAITERTH KONRAD UWE
IPC: E04B2/70
Filed: 1998-04-14
Abstract: The logs for a log-cabin wall are joined in interlocking end-to-end abutment. Each log has an end-face, which includes a re-entrant platform. All surfaces on the end-face, including the platforms and the block-surfaces between, face one way, i.e either towards the inside, or towards the outside, of the wall.      All the surfaces on the end-face of the interlocking end-face of the adjoining log face the other way. The logs are positioned laterally by means of spline-in-groove engagements with the logs above and below. The platforms are flat, parallel, and perpendicular to the block surfaces, whereby the end-face can be formed by simple saw-cuts. The spline in the log below serves as a watershed to prevent water passing inside, and the re-entrant platform is placed outside the watershed, and includes channels to collect water in the joint, and convey it back outside the wall.

Abstract: The present invention relates to a slot reuse method and arrangement for increase of the throughput in a DTM (Dynamic Synchronous Transfer Mode) network. The slot reuse according to the invention comprises extending the DTM  block token format to include parameters describing the segment(s) between source and destination node, reserving block token capacity only on the segment(s) between source and destination node, and enabling simultaneous transmissions in the same slot over disjointed segments of the network. The slot reuse can also comprise merging two or more segment-consecutive tokens, representing the same slot range, into a single token when existing in the free pool of a node.

Abstract: A compact multi-stage oil-water separator has application in removing oily contaminants from bilge water in ships. The oil-water separator has a final stage in which the flow of fluid is repeatedly reversed. the separator preferably has two toroidal mechanical separation stages on the suction side of a feed pump, and a cyclone separation stage and a filtration stage on the output side of the pump.      The cyclone separation and filtration stages are located inside the mechanical separation stages for compactness.

Title: Four mirror euv projection optics
Inventor: WILLIAMSON DAVID M
IPC: H01L21/027
Filed: 1998-09-18
Abstract: An all reflective ring field projection optic system for use in scanning photolithography used in the manufacture of semiconductor wafers. The projection optics are designed for wavelengths in the extreme ultraviolet ranging from 11 to 13 nm to provide an arcuate image field for a reduction step and scan photolithography system. A sequence or configuration of mirrors from the long conjugate end to the short conjugate end consists of a convex, concave, convex, and concave mirror with an aperture stop being formed at or near the second convex mirror. This sequence of mirror powers provides a relatively large image field size while maintaining a relatively compact reticle wafer distance of less than 900 mm. The projection optics form an instantaneous annual field of up to 50mm x 2mm at the wafer, permitting scanning to cover a field on a wafer of at least 50mm x 50mm, greatly increasing throughput. The optical projection system can print features as small as 0.05 microns.

Title: Process for the preparation of water purification solutions containing ferric iron and the use of the product as of obtained
Inventor: STENDAHL KJELL
IPC: C02F1/52
Filed: 1997-04-15
Abstract: The invention relates to a process for the preparation, from ferrous iron, of solution-form water treatment chemicals which contain ferric iron, to a granulated intermediate product obtained in the process, and to the use of the end products of the process. In the process, a raw material which contains ferrous iron in the form of an aqueous solution and possibly impurities is oxidized at an elevated temperature so that a precipitating, substantially pure ferric compound and a solution phase which contains the said impurities are obtained. The essential idea of the invention is that the precipitation is conducted in such a manner that part of the ferric iron precipitates in the form of goethite FeO(OH) or, in the presence of sulfate ions, in the form of hydronium jarosite H3OFe3(OH)6(SO4)2, while part of the ferric iron remains as a water-soluble ferric compound in the solution phase. Suitable raw materials include impure ferrous sulfate and pickling solutions which contain ferrous chloride. The precipitated pure ferric compound can further be separated by filtration or, alternatively, the slurry can be granulated to form a solid intermediate product and be later reslurried in water, whereupon a pure ferric compound can be separated by filtration. The pure ferric compound is dissolved in an acid, whereupon it is suitable as a coagulant for the purification of drinking water, and the solution phase is suitable as such as coagulant for the treatment of waster water.
