Filed: 2003-08-04
Abstract: Refractory metal products (12), such as tantalum on non-refractory conductive metal backings (14), e.g. copper, can be rejuvenated after metal consumption in selected zone by powder filling (28) the zones (18) and high energy heating (30) at high scan speed to sinter the added powder, without complete melting of the powder fill, thus establishing a microstructure consistent with the balance of the reclaimed product and avoiding the separation of the copper baking (14) and tantalum sputter plate (12). The rejuvenation method can be applied to non-mounted refractory metal products that are subject to non-uniform erosion, etching, chipping or other metal loss. The form of such refractory metal products can be as plate, rod, cylinder, block or other forms apart from the sputter targets. The process can be applied to, for example, X-ray disks or targets (molybdenum plate on carbon backing).

IPC: B41J2/495
Filed: 1968-08-06
Granted: 1971-05-10
Abstract: Di(aminophenyl)methane is produced by reacting 1 mole formaldehyde with 2 to 3 moles of aniline at 0 deg.-60 deg.C in the presence of HCl; the molar ratio acid: aniline is not higher than 1:1, Reaction is carried out until the presence of N-CH2-N (present in intermediaries) can no longer be detected. The product is pure and contains least 96% of the p,p'-isomer. It may be used as a curing agent for epoxy or polyurethane resins but in particular it may be directly phosgenated to give the diisocynate. This process fives diisocyanate which can be used directly for production of polyurethanes without purification.
Patent GB-1052367-A (GB)
IPC: B65G21/20
Abstract: 1,052,367. Endless conveyers. BUCCICONI ENGINEERING CO. Inc. July 5, 1965, No. 28319/65. Addition to 893,120. Heading B8A. The vacuum belt-type conveyer of the parent Specification is provided with mechanism for automatically opening the air passageways in the belt in timed relation to the advance of the article being conveyed without relying upon pressure of the articles against the belt. The belt has slits 62, 62<SP>1</SP> arranged so that when the normally bowed outermost face 56 of the belt is flattened the slits open up, Fig. 14 (not shown), and provide passageways between the bottom surface of the belt and a vacuum chamber 25. The mechanism for automatically opening the slits 62, 62<SP>1</SP> comprises roller assemblies 65 mounted on an eccentric sleeve 76 rotatably supported between a pair of longitudinal frame plates 67, 67<SP>1</SP>. Each eccentric 76 has a locking dog assembly 93 associated with it and is controlled by a cam 80 having an arm 81 actuated by a slide assembly 87. This assembly is operable by a cylinder 130, Figs. 5, 6, 9 (not shown). Operation.-An electric eye 16, Fig. 1 (not shown), detects the advancing movement of a sheet article and the slide assembly 87 is moved to the left thus releasing the arms 81 for counterclockwise movement. However, the dog assemblies 93 lock each succeeding cam 80. Initially the first cam 80 is rotated by the pressure of the belt B on rollers 75, 75<SP>1</SP> of the roller assembly 65 and rotation of this cam frees the next dog 93 which in turn frees the next cam 80 for rotation. Thus the cams are freed in succession and the associated eccentrics rotate so as to lift the rollers 75, 75<SP>1</SP>, which results in the vacuum passageway forming slits 62, 62<SP>1</SP> opening up just ahead of the leading edge of the advancing sheet. To release the sheet the slide assembly 87 is retracted by operation of the cylinder 130, the arms 81 and cams 80 are rotated clockwise and the rollers 75, 75<SP>1</SP> lowered against the belt to close the slits 62, 62<SP>1</SP>. In a modification, Figs. 18-21 (not shown), the roller mounting eccentrics and their associated dog assemblies are replaced by roller carrying assemblies which co-operate with each other in locking and unlocking positions.

Abstract: 1,053,929. Removing iron from phosphoric acid. DOW CHEMICAL CO. Nov. 19, 1963 [Dec. 6, 1962], No. 45579/63. Heading C1A. Iron is removed from an aqueous phosphoric acid solution by treating with a sufficient amount of an oxidising agent to convert the iron to ferric iron, adding sufficient HCl to provide a mole ratio of HCl to ferric iron of at least 4, and extracting the ferric iron with a water-insoluble organic amine and/or its organic salts in a liquid hydrocarbon solvent containing at least 35% by weight aromatic hydrocarbons. The amine is R 1 R 2 R 3 N, where R 1  is a benzyl or a C 6 -C 20  alkyl radical, and R 2  and R 3  each are H, benzyl or a C 1 -C 20  alkyl radical, e.g. primary amines such as tert-octylamine and tart-dodecylamine, secondary amines such as di-n-decylamine, di - (2 - butyloctyl) amine, di - (1 - isobutyl - 3,5 - dimethylhexyl) amine, N - benzyl- 1 - (3 - ethylpentyl) - 4 - ethyloctylamine; and tertiary amines such as tribenzylamine, tricaprylamine, tri - n - octylamine, butyldilaurylamine, dimethyloctadecylamine, tri - nhexylamine and methyldioctylamine. A tertiary amine of molecular weight 250-600 is preferred. The liquid hydrocarbon may be toluene, xylene, an aromatic naphtha or a hydrocarbon mixture containing at least 35% by weight aromatic hydrocarbons. The oxidizing agent may be KMnO 4 , MnO 2 , K 2 S 2 O 8 , Na 2 Cr 2 O 7 , H 2 O 2 , O 3 , NaOCI or Cl 2 . In removing iron from aqueous phosphate liquors containing a high concentration of calcium obtained by the decomposition of phosphate rock with 5-10% excess HCl, oxidation is effected with 3 parts Cl 2  per 1000 parts are passed into the liquor. Extraction is effected with a 5% amine solution batchwise or continuously in countercurrent or cascade processes with contact times of 0À5-5 minutes, and may be repeated. The amine may be regenerated for recycle by stripping iron with water or dilute caustic alkali.
