Abstract: ABSTRACT OF THE DISCLOSURE:            The present invention relates to a process for the produc-tion of grained abrasives from highly refractory inorganic hard materials with improved grain toughness, which is distinguished by the fact that a material in lump or block form, obtained by known processes for producing a finely cristalline internal struc-ture, is size-reduced and the grains subjected to grading by grind-ing in a ball mill or tube mill in such a way that essentially only the porous, faulty or coarsely crystalline grains are size-reduced and separated off from the rest of the material.  The pro-cess according to the invention is particularly suitable for im-proving the grain toughness of grained  finely crystalline abra-sives of the type obtained by melting aluminium oxide and/or bauxite or by melting zirconium oxide and/or Baddeleyite with pure aluminium oxide and/or bauxite, the zirconium oxide content amounting to between 0 and 60% by weight and preferably to between 20 to 45% by weight.

Abstract: Abstract of the Disclosure In the disclosed aquarium system, the aquarium water is purified in a biological/mechanical external filtration means which can also include chemical adsorption elements, if desired.         The filtration means typically comprises (a) a pre-filtration zone, containing a relatively "coarse" filter element (e.g. with a pore size greater than 100 microns), and (b) a parallel flow zone containing a "fine" filter element (e.g. with a pore size less than 100 microns) and at least one cultured filter element.  The culture of the cultured filtered element typi-cally contains nitrifying bacteria, which help keep the free ammonia concentration in the aquarium system at a low, non-toxic level or even negligible level.  The "fine" filter element in parallel with the cultured filter element permits high flow rates through the system and removes fine detritus.  Thus, the parallel flow zone permits rapid and efficient biological/ mechanical (or, if desired, biological/mechanical/chemical) filtration coupled with low fluid flow resistance.  The "coarse" filter in the pre-filtration zone removes coarse detritus.  When a culture forms in the detritus trapped in the "coarse" filter, the resulting cultured filter is useful as a biological ele-ment in the parallel flow zone of the same (or different) filtration means.

Abstract: ABSTRACT OF THE DISCLOSURE         Wire is continuously delivered to one of two vessels both filled with a salt bath maintained at a predetermined tem-perature.  Inside each of the vessels is provided a vertically displaceable support onto which the wire is lowered, quickly taking on the same temperature as the salt bath.  When a pre-determined quantity of wire has been loaded into the one vessel the wire is cut and is loaded into the other vessel while the support is lifted out of the first vessel and the bundle of wire is removed from it.  Thereupon the support of the firs  vessel is lowered back down to take on another charge of wire.

Abstract: Abstract of the Disclosure Undesirable molecular weight protein and polyphenol molecules can be removed from aqueous liquids or suspensions, such as wort, wine, or beer, by contacting the liquid with acid-treated synthetic magnesium silicates containing less than about 14% magnesium oxide. The resultant liquid is more resis-tant to chill haze formation. Even better results are obtained if a polyamide is blended with the acid-treated synthetic silicate prior to contact with the liquid. A filter aid, such as diatomite, can also be combined with the acid-treated synthetic magnesium silicate and/or the blends containing the polyamide.

Abstract: DISPOSABLE LIQUID STERILIZER UNIT          Abstract of the Disclosure A disposable liquid sterilizer unit incorporating an ultra-violet tube designed to generate radiation at approximately 2537 Angstroms is disclosed.  The unit comprises an elongated cylindrical plastic jacket opaque to ultra-violet radiation concentrically mounted about the tube to provide a chamber between the jacket and the tube for the flow of liquid to be exposed to radiation generated by the tube.  The tube extends beyond the ends of the jacket and includes electrical connectors at each end for removably mounting the unit to make electrical connection with electrical connections in a casing.          A seal is provided adjacent each end of the jacket against liquid flow from the chamber between the tube and the walls of the jacket to the exterior of the jacket.  Inlet and outlet connections for the flow of water to and from the chamber are provided as well as a viewport through the plastic jacket.          The jacket includes a central portion and two integral injection moulded end portions fixed to the central portion by an adhesive.  The moulded end portions include the inlet and outlet connections.  The complete unit can be readily removed from the casing and disposed of when the tube is defective or worn out.  One circuit arrangement provides a visual warning, while another prevents the flow of liquid past the tube when insufficient current to achieve sterilization is flowing through the tube.

Abstract: A PNEUMATIC VEHICLE JACK            Abstract of Disclosure:   A pneumatic vehicle jack comprises a jack cylinder with a body and a piston rod assembly movable to each other, two levers pivoted to said body or piston rod assembly, located on either side of the longitudinal axis of the jack cylinder and carrying vehicle and ground engaging shoes, and two struts pivotally mounted between said levers on the one hand and said piston rod assembly or cylinder body on the other hand. A cartridge of compressed gas can be removably adapted onto said jack cylinder for actuating the same. Actuation of the jack cylinder causes the pivot points of the levers and struts to be brought closer together, to move the shoes away from each other. At the beginning stage of the actuation movement, the lever system comprising the levers and struts reduces the force exerted by the jack, and at the end of the said movement it increases said force. Because the volume occupied by the gas contained in the cartridge increases during the actuation of the jack, the force exerted by the jack cylinder progressively decreases. Thus, the lever system compensates for this decreasing force and a substantially constant force is exerted by the vehicle jack in its whole, and the raising movement of the vehicle is also progressive and constant.
