Title: Apparatus and process for direct chill casting of metal ingots
Inventor: BRYSON NEIL B
IPC: B22D11/041
Filed: 1991-06-13
Abstract: In direct chill casting of aluminum alloys, and particularly the casting of ingots of large cross section, macrosegregation is significantly reduced and compositional uniformity is greatly improved across the formed ingot, if the casting is carried out using a flow directing device, such as a baffle (25) or flow velocity accelerator (50), adapted to direct a major portion of the molten metal feed centrally downwardly and into substantially the bottom of a liquid zone or sump (16) formed during the casting and then outwardly and upwardly along an interface (21) between the liquid sump (16) and surrounding solidified metal (20). This ensures that the hottest metal is fed downwardly to the central core of the ingot at the bottom of the sump.

Title: Device for cleaning chimney flues or like passageways
Inventor: NUNN BERNARD J
IPC: F23J3/02
Filed: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE          A device for cleaning chimney flues or like passageways comprises a multiplicity of generally planar strips of flexible, resilient plastic sheet material each having a length several times greater than its width, the strips having their central areas secured together so that their outer end areas extend radially from the centre, the central areas having a mounting for fixing to a flexible cleaning rod.  The strips each have a rounded end and are disposed in overlapping but slidable relationship to each other so that their ends define a circle when viewed along the axis of the device.  The flexibility of the elements and the fixing and mounting arrangement are such that the device can be pushed through a passageway considerably smaller in diameter than the length of the strips.  The strip ends perform a scraping action, and are not substantially deflected sideways.

Title: Fuzzy reasoning apparatus and method of monitoring operation thereof
Inventor: TSUCHIYA NOBUO
IPC: G06N5/04
Filed: 1991-10-28
Abstract: ABSTRACT      If input values (input variables x1 x2,..., xn) applied to a fuzzy inference engine (1) fall within a range of defined reasoning rules that have been set in the fuzzy inference engine (1), a fuzzy reasoning operation is performed correctly and an output value obtained as a result of this operation is delivered through a selector (6).  In a case where an input value is outside the range of defined reasoning rules owing to, say, an error in the setting of the reasoning rules, the memberships of the antecedents of all rules becomes zero and the fuzzy reasoning operation can no longer be performed.  The number of times this state in which the reasoning operation is disabled is counted by a counter (3).  If this state continues successively for a prescribed number of times (C), a specified output value Ys set previously in a memory (4) is delivered through the selector (6).
Patent CA-2095929-A1 (CA)
Inventor: BROWN KENNETH D
IPC: B44C7/00
Filed: 1992-09-14
Abstract: A package comprising a sealed container containing a roll of wallcovering material which comprises a hydrophilic sub-strate layer, a pressure sensitive adhesive layer on one surface and, on the other surface, a decorative layer, usually including a layer of PVC or other plastics material. The wallcovering material is preferably self-wound on a roll. The moisture content of the wallcovering material is controlled in the package so as to provide a desired area of the product which falls between the area of the product where it is soaked in water under predetermined conditions and the area of the product when it is preconditioned un-der relatively dry, predetermined conditions. The moisture content is generally above the equilibrium content under normal am-bient conditions so that any problems caused by expansion of the product in use under humid conditions, such as bubbling and raising of the edges of the material at seams, are minimised. In a process for producing the product the moisture content is moni-tored during the process, usually downstream from a drying stage, for instance the drying stage following application of an aque-ous adhesive.

Title: Process for producing particles and coating films of titanium oxide
Inventor: OKADA MIZUHO
IPC: C01G23/047
Filed: 1993-07-27
Abstract: ABSTRACT         The present invention relates to a process for producing titanium oxide particles and a process for producing a titanium oxide coating film.  The titanium oxide particles are produced by subjecting a suspension of titanium oxide fine particles to a hydrothermal treat-ment at 100°C or higher at a pH of a specific range to carry out crystal growth of the fine particles.  The titanium oxide coating film is produced by suspending the thus obtained titanium oxide particles in water, adjust-ing the suspension to a pH of a specific range, coating the suspension on a support and then firing the coat to allow the titanium oxide particles to firmly adhere to the support. The titanium oxide particles and titanium oxide coating film obtained according to the present invention are used as pigments, ultraviolet absorbers, fillers, optical materials, electronic material, optoelectric transducing materials, decorative materials, catalysts, photocatalysts, catalyst carriers, adsorbents and bioreactors.

Title: Process for preventing the formation of harmful organic substances and steam generator for carrying out the process
Inventor: BOBIK MICHAEL
IPC: B01D53/70
Filed: 1992-12-17
Abstract: ABSTRACT     For the reduction of the formation of dioxin and/or furan it is suggested to increase the SO3/SO2 ratio in the combustion gas so that a minimum SO3 content of 10 mg/m3 is obtained.  The maximum content therein is not to exceed 500 mg/m3.  The ratio SO3/SO2 can be modified by adding SO3 or also catalysts or oxidizing agents which convert SO2 to SO3 while maintaining the same total quantity of sulfur.  Constructionally is suggested a steam generator whose steel structures coming into contact with the combustion gases are either alloyed with tungsten and/or vanadium or are coated at the combustion-gas side.

Title: Wafer Holding Apparatus for Holding a Wafer
Inventor: UEDA MINORU
IPC: H01L21/683
Filed: 1993-10-26
Abstract: A wafer holding apparatus for holding a wafer stationary includes a main body and a plate member detachably placed on the main body. The main body includes a cavity having an open end at the upper surface of the main body and includes a passageway extending from the cavity to communicate the cavity with a vacuum pump. The plate member is placed on the main body to plug the open end of the cavity and supports on its upper surface a wafer to be processed. The plate member has a number of through bores arranged in a predetermined arrangement matched for the arrangement of micromachined sections of the wafer where micromachines or integrated circuits are to be formed. Before processing of the wafer, the plate member is selected for the wafer in such a manner that the through bores of the plate member are deviated from the micromachined sections of the wafer where the micromachines are to be formed. This results in the micromachined sections being protected from the suction force caused by the vacuum pump, thereby making it possible to enhance the productivity of the wafer.

Title: Process for re-use of water-containing plant material
Inventor: HABEGGER ERNST
IPC: B09B5/00
Filed: 1994-02-25
Abstract: Abstract In a process for re-use of water-containing plant material (1), the latter is pulverized and cellularly decomposed, preferably with the addition of water, using mechanical means (16).  In particular, perforated disk, corundum disk, toothed colloid or hammer mills are suitable for cellular decomposition.          The plant material treated according to the invention can be selectively stored on an interim basis or applied directly to the soil or vegetative cover.  In  caring for qualitatively superior grass surfaces, preferably the cellularly decomposed material is also filtered or in some other way separated into a fibrous portion and a liquid portion.  While the nutrient-rich, valuable liquid portion (cell contents) is being applied to the grass surface, the fibrous portion (cell walls) is re-used in a different way.  The process can be implemented with stationary or mobile devices.  In the latter case the device is used alone or in combination with a mower so that the grass clippings can be cut, pulverized, cellularly decomposed and re-applied in one or several operations.
