Abstract: Shelf-stable complete pre-mixes, separated into two or more components. The components are chemically and microbially stable. At least one component is a high-water-activity liquid component. The components, when combined, provide all ingredients necessary to form uncooked mixes or food and beverage products.

Abstract: A water-lubricated bearing comprises a cylindrical shell and a resilient liner, said shell being formed from a hard plastics material by a casting process and including an integral outwardly radially-directed flange at one end region thereof. The bearing may be made by initially forming the liner from a curable plastics material and curing the said material and thereafter forming the shell by casting a settable material in situ about the liner.

Abstract: A backwash filter system includes a filter array comprising a plurality of filter units each having a housing, a filter element unit and a process liquid inlet port and a filtered liquid outlet port connected respectively with process liquid inlet and filtered liquid outlet sides of the filter element unit for filtering process liquid. A process liquid inlet header connects to the process liquid inlet ports of the filter units. A filtered liquid outlet header connects to the filtered liquid outlet ports of the filter units. A first valve unit on the process liquid inlet header is switchable for connecting same alternatively to a process liquid source and a backwash liquid drain. The filtered liquid outlet header can communicate with a filtered liquid receiver.

Abstract: The present invention provides a method of making quinolone carboxylic acids or naphthyridine carboxylic acids in free base form, the method comprising dissolving a quinolone carboxylic acid salt or naphthyridine carboxylic acid salt in a solvent system to form a solution; combining the solution containing the quinolone carboxylic acid salt or naphthyridine carboxylic acid salt with a calcium salt in an amount in the range of about 0.01% to about 5.0% by weight of the quinolone carboxylic acid salt or naphthyridine carboxylic acid salt and a base, the combination resulting in the formation of a precipitate; and collecting the precipitate. Also provided is a solid bulk pharmaceutical chemical composition comprising 7-(3-amino-1-pyrrolidinyl)-8-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-o xoquinoline-3-carboxylic acid or 7-?3-S-(2-S-aminopropionylamino)pyrrolidin-1-yl!-1-cyclopropyl-6-fluoro-1, 4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid; and calcium in an amount in the range of 0.001% to about 1.

Abstract: A replaceable jaw face (10a-10d) for a jaw crusher for crushing rocks and the like comprises corrugations (c) the axes of which are inclined to the vertical such that there is a lateral phase shift of the corrugations between the upper and lower end edges (16,18) of the face. This configuration provides interchangeability of the jaw faces throughout the jaws of the crusher while maintaining the correct relationship between the corrugations of the jaw faces of the opposing jaws.

Abstract: A piano having a sound-enhancing system incorporating transducers, amplifiers and loud speakers, all incorporated into or upon the piano.

Abstract: The invention provides a tundish comprising a casing having a floor, including an impact area, and upstanding sidewalls, the casing having a permanent refractory lining, and at least one expendable beam of refractory heat insulating material extending between opposite sides of the casing adjacent the impact area. Generally the refractory heat insulating material is one comprising a major proportion of particulate refractory, a minor proportion of fibrous material and an organic binder. In the tundish there may be two pairs of said beams to bridge opposite sides of the casing, one pair being located at the sides of the impact area in or on the floor of the casing and the other vertically above the first, adjacent the top of each sidewall.

Abstract: A bimetallic tube comprising a copper-base alloy and a reactive metal such as titanium, is produced by assembling concentrically a tubular member of each of such materials and interposing a layer of copper, nickel or silver between them, forming a bond between the reactive metal and the copper, nickel or silver and extruding the assembly. The bimetallic tube is useful for heat exchange purposes when corrosive fluids are involved and has better heat transfer properties than an all-reactive metal tube.

Abstract: The present invention relates to blowing agent compositions, to foamable thermoplastic compositions, to a process for preparing articles obtained by foaming such compositions, and to the articles obtained by such a process.

Abstract: A data decoder is provided which is useful for decoding data magnetically encoded on a magnetic stripe on the back side of a credit card which may be manually moved through a reader at a variable velocity. The data is decoded by comparing the occurrence of voltage pulses after the onset of a bit interval, representing binary data encoded as magnetic flux changes, with a preselected portion of the measured time duration of the preceding bit interval. If a voltage pulse occurs after the onset but before the end of the preselected portion, the data is determined as a binary "one"; if a voltage pulse occurs after the end of the preselected portion, the data state is determined as a binary "zero".

Abstract: In conventional processes for separating metals by selective precipitation, the precipitate is frequently in an amorphous form, eg a slime, which is difficult to filter, wash and handle generally. In the present process mixed solutions and/or sols of the metals are mixed with a suitable soluble organic polymer to form a viscous mixture. The latter is formed into discrete entities, e.g. drops, which are contacted with a reagent which converts each drop to a gelled entity containing at least one of the metals as a precipitate.In one form of the process, the same chemical reagent also serves to dissolve the other metal present in the initial drops. The metals are then easily separated by separating the gelled drops from the reagent. In another form, the reagent includes two different chemical reagents which contact the drop simultaneously, one to precipitate one metal in the gelled drops and the other to dissolve the other metal.

Abstract: A mobile dust extraction apparatus having a self cleaning filter feature has an extractor blower in fixed position; a lower storage chamber having a valved inlet at one end; an upper plenum chamber having a valved outlet at one end and a valved vent at the other, a filter between the storage and plenum chambers and a detachable connection between the blower and the plenum chamber so that the plenum and storage chambers may be moved relative to the blower.
