Granted: 1992-04-01
Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.

Abstract: In the economic production of hydrolysed zirconiferous precipitate, hydrolysis is carried out by the addition of base to aqueous acidic zirconium sulphate solution, to lower the H<+> to and maintain within a pH range of 3 to 7, preferably within 4 to 6. The base may be selected from ammonia, basic ammonium salts, e.g., ammonia-buffered ammonium salts, an alkali metal hydroxide, carbonate or bicarbonate. Specific bases include ammonia and ammonium/sodium/potassium hydroxide, carbonate or bicarbonate, with particular preference for ammonia and ammonium/sodium hydroxide. The starting materials may be incorporated in batchwise or continuous fashion, batchwise by combining them in a body of water, suitable electrolyte or solvent with thorough continuous mixing or continuously by mixing them together in a flowing stream. An additive in the form of an inorganic stabiliser or an organic surfactant may also be included. Inorganic stabilisers may be selected from one or more of Y2O3, Ce2O3, Al2O3, MgO and CaO or precursors thereof. In the finishing stage, either further base may be added to lower residual sulphate content or acid added to remove acid-soluble impurities. The precipitated product is then separated, (e.g., by filtration), washed and calcined to give pure zirconia. High purity zirconia has particular application in the electronics industry and for the production of partially stabilised zirconia ceramics.

Granted: 1994-06-15
Abstract: The invention relates to a method of correcting errors in encoded uncorrected data in a disk storage device, employing a multiple level error correction code for use with records of varying length, including initially formatting the data into blocks, each comprising subblocks, which, except for possibly the last, are of equal size, the number of subblocks in any record being determined by the length of that record. The method is characterised by the steps of statistically determining, as a function of subblock size, first level correction capability and the length of the longest record anticipated, a number representing the minimum number of subblocks which may be in error and correctable; transmitting the uncorrected data to a storage director; performing at least a portion of the first level of error correction at the storage device; and, after all uncorrected data has been received by the storage director, transmitting error information reflecting first level error pattern and location to the storage director for completion of the first level of correction and performance of subsequent levels of correction. The invention also relates to apparatus for performing a method of correcting errors as above.

Date Dec. 29, 1988.The connecting end on a coupling sleeve has an annular flange which may be hoved to urge compression stress to an annular deformable sealing ring to establish a seal between the main pipe and coupling sleeve. A stop part flange is positioned to one side of a sealing couple and which may assume a fixed position relative to the wall of the main pipe against which the stop part rests. Pivoted link stretching elements on the coupling sleeve move the insertion end of the branch pipe outwards relative to the wall of the main pipe and provides structure for exerting a compression stress against the resilient sealing ring to effect a seal between the coupling and main pipe. After securing the coupling sleeve in a sealing couple the connecting end and the insertion end assume a fixed predetermined position relative to the main pipe with use of stretching means which comprises at least two identical lever elements which are positioned at equal spacings about the periphery of the coupling sleeve and which are each capable of setting a predetermined fixed distance between fixed points connected to the outside periphery of the insertion end and the stop part.

Title: Extruded gelled products
IPC: A23L1/0522
Filed: 1989-05-16
Granted: 1992-08-05
Abstract: A process for the extrusion of gelled products, such as jelly gum confectionaries or pharmaceutical products, in a cooker or former extruder uses unique spray-dried pregelatinized high amylose starches alone or in blends with selected starches to provide extrudates which quickly set and form gels. The products typically contain 10-18% of the starch (on a dry solids basis), 70-90% of a sweetener, up to 20% water, and up to 20% of conventional confectionary or pharmaceutical ingredients. The mixture may be heated to about 93 DEG C (200-240 DEG F) prior to extrusion to provide a flowable mixture. The spray-dried, pregelatinized high amylose starches (unmodified or modified) are prepared by a simultaneous steam atomization and spray-drying by process which provides a pregelatinized granular starch or a continuous coupled jet-cooking and spray-drying process which provides a pregelatinized dispersed starch which is substantially non-crystalline and substantially non-retrograded.

Abstract: New heparin derivatives having antithrombotic activity, also endowed with reduced hemorrhagic and anticoagulant effects, obtained by treating in a basic medium heparins of various origin, optionally in the presence of alkali metal salts and of a reducing agent. The heparin derivatives obtained through this treatment show peculiar chemico-physical characteristics, like new signals at about 53 and 54 p.p.m. in the <1><3>C-NMR spectrum and a raise of the specific rotatory power, compared to that of the starting heparins, to values between +50 DEG  to +90 DEG . Said structural modifications produce an improvement of the biological properties of the heparin, substantially keeping the antithrombotic activity while diminishing the hemorrhagic effect in vivo and the anticoagulant activity in vitro.
