Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a process for the recovery of molybdenum-99 from an irradiated uranium alloy target.    This process comprises the following stages:   a)   dissolving the irradiated uranium alloy target in sulphuric acid, b)   separating the iodine and tellurium present in the thus obtained solution, c)   oxidizing the molybdenum-99 present in the Mo (VI) solution, and d)   extracting the thus oxidized molybdenum-99 with a hydroxamic acid of formula:                             (I) in which R is a radical chosen from the group including straight or branched-chain alkyl radicals, the phenyl radical, phenyl radicals substituted by at least one alkyl radical, arylalkyl radicals and the cyclohexyl radical and R' is a hydrogen atom or an alkyl radical.     The hydroxamic acid can be tri-n-butylacetohydroxamic acid and the molybdenum recovered can be used in a technetium generator for medical purposes.

Title: Method for making sintered aluminous abrasive  particles
Inventor: MELOON DAVID R
IPC: C09K3/14
Filed: 1986-02-03
Granted: 1988-10-04
Abstract: Abstract of the Disclosure A method of making  sintered aluminous abrasives from uncalcined bauxite.  The uncalcined bauxite is mixed with sulphuric acid and dissolved.  This forms aluminum sul-fate hydrate as a major product.  The aluminum sulphate hy-drate is then dried to form aluminum sulphate which is then calcined to form gamma alumina and sulphur trioxide.  The sulphur trioxide is mixed with water to form sulphuric acid and is then recycled for further use as additional dissol-ving material.  A slurry of the gamma alumina is prepared, poured into a container and then dried to form a cake known as an unfired body.  The unfired body is then broken into particles and screened to size.  Following this, the par-ticles are sintered.   The sintered particles are finally cooled, then screened into the various desired abrasive grit sizes.  Alternate methods for forming the unfired body in-clude: 1) extrusion of a paste made up of gamma alumina and water followed by drying of the extruded material; and 2) pressing the dry gamma alumina into compacted cakes.

Title: Machine for simultaneous cutting and forming of tube ends - has a cutting wheel whose feed rate is controlled during cutting
IPC: B21D41/04
Filed: 1973-04-04
Abstract: The machine for simultaneous cutting of the tube and for tube end forming is used for example for cutting of pipes. The pipe ends are conically deformed during the cutting in controlled manner. The cutting wheel is arranged at the end of a rocking arm, moved during cutting. The pipe ends formed are suitable for making press fit connections. The rotating cutter blade is rotated by a drive belt and a gear wheel. The rocking arm which supports the cutter is actuated by the disc cam. Two parallel pipes are cut on the machine. The cutting wheel continuously rotates whilst it is lowered by the movement of the cam into the pipes for cutting purposes. The pressure exerted during cutting deforms the cut ends of the pipes depending on the cam actuation.
