Patent CA-2022665-C (CA)
Title: Forming fabric with interposing cross machine direction yarns
Inventor: WILSON ROBERT G
IPC: D03D13/00
Filed: 1990-08-03
Granted: 1999-01-19
Abstract: A papermakers' fabric, especially a forming fabric, with very high fiber support and open area on its top surface for superior papermaking characteristics.  The papermaking surface consists of a woven fabric layer with single float machine direction yarn knuckles; i.e., no machine direction yarn passes over two or more adjacent top surface cross machine direction yarns.  To complete the papermaking surface, into this base structure is woven two additional, generally smaller diameter, cross machine direction yarns for every cross machine  direction yarn in the base weave papermaking surface.  These two additional cross  machine direction yarn pairs are woven in reverse weave patterns to one another such that natural interposing forces cause the two yarns to align one over the other centrally between two adjacent cross machine direction yarns of the fabric layer.  One yarn of the interposing pair functions as an additional fiber supporting yarn while the other yarn acts as a locator yarn to position the fiber supporting yarn in the proper or ideal location on the papermaking surface.

Title: Totalizer apparatus for flow rate measurement devices
Inventor: WILDBERGER JOHN
IPC: G01D18/00
Filed: 1990-08-03
Granted: 1994-10-18
Abstract: A totalizer apparatus, for use with belt scales and other flow rate measuring devices producing output signals subject to zero drift,  maintains an auxiliary totalizer register during zeroing operations so that should zero flow conditions be interrupted during such an operation, a correct total can still be maintained.   This enables autozeroing operations to be implemented, for which purpose a further auxiliary totalizer is used to test for an extended absence of  flow before permitting  initiation of  an  autozeroing operation.  If a zeroing operation results in an apparently excessive zero correction, it is rejected and assumed that flow has restarted during the operation: the first auxiliary totalizer register is used to update a primary register.

Title: Sanitary fitting
Inventor: HOCHSTRASSER FERDINAND
IPC: E03C1/04
Filed: 1990-12-12
Granted: 1994-05-17
Abstract: ABSTRACT OF THE DISCLOSURE           A sanitary fitting includes a fitting housing which has a fixed housing part which is overlapped by a jacket element which can be swivelled about an axis.  Projecting toward the front from the jacket element is a nozzle in which a guide bush is inserted.     Together with the inner wall of the nozzle, the guide bush bounds a jacket space which is connected to the surroundings by a passage.          Furthermore,  the jacket space is communicated by an aeration passage to an annular channel which is communicated by an aeration line to an aeration aperture of a safeguard mechanism.  Water fed through a feed line is mixed in a control cartridge and flows through the safeguard mechanism,  connected downstream from the control cartridge, and through a pipe into a hose to a shower.  In the case of conditions permitting backflow of water into the feed line, the safeguard mechanism prevents backflow and aerates the pipe and the hose while exposing an aeration aperture.  Any water thereby escaping through the aeration aperture is conducted through an aeration channel into a deeper part of a sink.

Granted: 2001-06-05
Abstract: An elongated, rod-like rack for use in an automotive-type steering gear assembly and like mechanisms, is formed of an elongated extruded tube divided lengthwise into a substantially solid rack portion and a substantially hollow, link portion.      Transversely extending teeth are broached on the rack portion for engagement with a drive pinion means and the like for transmitting power through the rack. The rack is formed by positioning a tubular blank within an open ended extrusion die having an extrusion throat and partially pushing the tubular blank through the throat for extruding the material longitudinally and collapsing radially inwardly to form a substantially solid, elongated rack portion. Then, the extrusion is continued with a punch having a mandrel arranged within the blank and within the die throat for extruding a thin wall length, forming the hollow, integral link part of the rack. The trailing end may be terminated in an inwardly extending, thick wall portion suitable for forming threads thereon. The elongated rack part has a fine, axially extending opening along its length resulting from a space left when the material is inwardly collapsed in the dae throat for providing a communication passageway.

Abstract: An aircraft launched pyrotechnic decoy flare (1) which comprises a pellet (2) configured with a cavity (4) which extends along a fore-and-aft axis (8) of the pellet (2) and is vented at its rearward end (12).  Part of the external surface of the pellet (2) is covered with a casing (16) to prevent combustion of said part of the surface.  The pellet (2) is made of a gassy pyrotechnic composition including an organic binder, and an oxidising halogenated polymer and an oxidisable metallic material which react with each other on ignition and emit infra-red radiation.  When the flare (1) is ignited the surface of the cavity (4) combusts and produces hot gaseous products which escape from the cavity (4) through the vent (22) thus propelling the flare (1) in a forwards direction.  In this way the flare (1) can be propelled in the same direction as the aircraft to reduce the rate at which the flare (1) separates from the aircraft exhaust.

Granted: 1998-06-23
Abstract: Pertactin (formerly 69 kDa protein) is recovered in stable biologically pure form having no detectable adenylate cyclase activity from fermentation broth from the fermentation of Bordetella pertussis as well as from the cells. The broth is processed to selectively remove pertussis toxin (PT) and filamentous haemagglutinin (FHA), the pertactin is precipitated by ammonium sulphate and the precipitate is dissolved in buffer at pH 6.0 to 8.5, the solution then is passed through hydroxyapatite and ion-exchange chromatograph columns before final ultrafiltration. Cells are extracted with urea and the extract ultrafiltered and diafiltered. The pertactin is precipitated from the extract and the precipitate processed as above. In a variation, the broth is contacted with ammonium sulphate to precipitate pertactin, PT and FHA, the precipitate is dissolved and the PT and FHA selectively removed, before the solution is passed to the chromatograph columns.

Title: Method and system for color film separation preprocess using electronic object-based choking and spreading procedures including object combining operations
Inventor: BOENKE MARKE
IPC: G06T11/60
Filed: 1992-10-29
Granted: 2003-02-04
Abstract: A computer system 100 for production of ink separations from an object-based print pre-process apparatus using a page description language. The print pre-process system facilitates creation of object spreads for any combination or configuration of objects on the rendered page. For each object on a rendered page, the computer system 100 makes use of a spread table to determine spread incidences. For each spread incidence, the computer system generates set union, intersection and difference for spreading, receiving, and obstructing objects by use of a modified Weiler algorithm. The modified Weiler algorithm creates a simplified graph of contour histories providing a visible portion of the spread object. The visible object is strokable within a clipped window set to the receiving object. The stroke color and width, set by the spread table, can be knockout print or overprint.
