Title: Cooling method of continuous casting and its mold
Inventor: OHATAKE NORIO
IPC: B22D11/124
Filed: 1992-09-01
Abstract: A cooling method and a cooling mold in a continuous casting wherein even if a continuous casting rate is increased, a proper cooling is carriedout to prevent a danger of a breakout, so as to improve the stability of casting and the high quality of an ingot (4). A cooling mold comprises water cooling jackets (21, 22) which are provided in the inner part of the mold (2), a first cooling water jetting mouth (23) which is arranged at a distance of 20 to 45 mm between a contact position of a primary cooling water and an other contact position of a secondary cooling water on the ingot (2). By use of the cooling mold (2) wherein a primary and a secondary cooling water impinging angles are respectively set at 15 to 30 degrees and at 30 to 60 degrees, the primary cooling water is impinged from the first cooling water jetting mouth (23) to a molten metal (3) which is cooled with the inner surface of the cooling mold (2) to carry-out a primary cooling, and nextly, the secondary cooling water is impinged from the second cooling water jetting mouth (24) to initial zones of a transition boiling zone and a film boiling zone which are produced with the impingement of the primary cooling water, so that a vapor film generated in the transition boiling zoneand the film boiling zone is broken out to provoke a nucleate boiling so as to carry out a direct se condary cooling with the secondary cooling water. <IMAGE>

Patent CA-2079238-A1 (CA)
Inventor: FYLES THOMAS M
IPC: D21C11/00
Filed: 1991-02-08
Abstract: It has been found that certain chemicals such as peroxide may be concentrated in an aqueous solution by increasing the pH of a feed liquor to increase the amount of the chemical in an ionized form, i.e. increase the ionized fraction and then separating the feed liquor by reverse osmosis through a reverse osmosis membrane into a retentate having an enhanced concentration of chemical in ionized form relative to the feed liquor and a permeate having a reduced concentration of chemical in ionized form relative to the feed liquor. The process is particularly suited to increasing the concentration of hydrogen peroxide.
Patent CA-2079972-A1 (CA)
Inventor: SANTIAGO CLAUDIO VAZ
IPC: D04H1/4266
Filed: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a process comprising processing and/or  cleaning  fibers  and  opening  them,  with  the composition then being formed.  Thereafter, the material so prepared undergoes carding or is formed into a membrane with optional needle-shaping. In the needle-shaping, the fibers are intertwined by means of specific needles, while in the absence  of  needle-shaping,  the  membrane  is  carded  or pneumatically condensed.  The membrane obtained by such a process can be formed for specific uses into strips,  or compacted parts having a certain flexibility by pressing, so forming parts with multiple forms or totally planar parts. For  special uses of the membrane,  thermoplastic  fibers having a low melting point (between 100 and 160 degrees C) can be used, mixed in the composition, which will act as binder/structural agents in the thermoformation process of the material.  Structural or higher-rigidity parts can be obtained with temperatures ranging from 170 and 200 degrees C and pressures between 1 to 20 kg/cm2.   The resulting membranes can be used for the manufacture of soft parts which   are   smooth   and   flexible,   by   low-pressure thermoformation, so as to preserve the original softness and flexibility,  and also to provide form thereto,  or heat transmission, either by convection or a direct transfer, or inputting of hot air can be applied.
Patent CA-2081400-A1 (CA)
Title: Frequency synthesis using frequency controlled carrier modulated with pll feedback signal
Inventor: ICHIHARA MASAKI
IPC: H03L7/18
Filed: 1992-10-26
Abstract: In a frequency synthesizer, a phase detector receives an externally-generated reference clock signal of a constant frequency and a feedback signal to produce an error signal, which is output through a loop filter to a voltage-controlled oscillator (VCO). A direct digital synthesizer (DDS) receives the reference clock signal and externally-generated phase data to produce a DDS output signal whose frequency is precisely controlled by the phase data. The DDS output signal is applied as a carrier to a differential detector where it is modulated with the output of the VCO to produce a signal corresponding to the lower sideband of the modulated carrier. The output of the differential detector is output to the phase detector as the feedback signal.

IPC: C08L71/02
Filed: 1991-04-22
Abstract: Cyclodextrin complex is suspended in polyalkylene glycol carrier material that does not displace the included material. The preferred perfume/cyclodextrin complexes, either alone or admixed with solvent (e.g., water), are preferably suspended in the carrier and then incorporated into solid, dryer-activated, fabric treatment (conditioning) compositions, preferably containing fabric softeners, more preferably cationic and/or nonionic fabric softeners. The perfume complexes provide fabrics with perfume benefits when they are rewetted after drying. Volatile perfume materials, including those materials that are commonly associated with "freshness" can be applied to the fabrics in an effective way.

Patent CA-2115864-A1 (CA)
Inventor: SIEBER ROBERT
IPC: B44C1/17
Filed: 1994-02-17
Abstract: Abstract of the Invention A two-step press type transfer operation is made practical by a particular rendering of pictorializations for use upon the transfer sheets. A pictorialization should have a major portion of some object in the center of the pictorialization or a portion of a pictorialization in which a segmentation or division of such pictorialization is to be made so that one portion of the pictorialization may be placed upon one transfer sheet and a second portion of the pictorialization placed upon a second transfer sheet.  Substantial straight linear portions of such pictorialization of this area are avoided and the division between the two portion of the image are run along nonlinear borders upon the edge of clearly defined structures within the pictorialization. A translucent flap is also maintained on the edge of the transfer sheet so that upon placing a second transfer sheet over a first pictorialization already applied to a garment or the like, the flap protects the underlying pictorialization from damage by the hot press.  The invention allows "seamless" or "wrap around" pictorializations to be applied to garments using presses which are otherwise too small to press the entire transfer sheet at one time.
Patent CA-2116143-A1 (CA)
Title: Method and apparatus for saving printer memory
Inventor: COOPER MICHAEL D
IPC: G06F3/12
Filed: 1994-02-22
Abstract: ABSTRACT OF THE DISCLOSURE   A page printer uses alternative internal representations for the print data in each of multiple lateral strips that make up the page. Page description language input is converted to an intermediate display list format that is sorted into display commands associated with each strip. If during input the display list representation of the data fills the memory allotted to its storage, one or more of the strips is converted from display list format to raster format and compressed using a lossless compression algorithm. If storage of compressed strips subsequently exceeds available memory, raster data is further compressed using a lossy compression algorithm. Additional display list commands are rasterized by decompressing the compressed strips, processing the new commands and recompressing the data using lossless or lossy compression as required. If the display list does not overflow memory during input, the complete strips are rasterized and compressed one at a time in the order in which they will be printed. The rasterizing time is stored. Should memory overflow at any point in the process, then the rasterizing times for the remaining strips are determined without storing the raster output. A decision can then be made for each strip to rasterize it to the print engine on the fly, pre-compute and store it as lossless compressed raster data, or revert to a lossy-compressed pre-computed version.
