Abstract: 本发明涉及一带有由Ni和/或Co以及进入的非金属元素C和/或S，在一定情况下还附加有Fe，In，Pd，Au和/或Bi的表面镀层的冷轧带钢的热处理方法，其中冷轧带钢具有低碳含量。因为当不发生再结晶时，沉积在晶界上的由C，S，N和P与表面镀层金属形成的化合物促成主要的微裂纹，则热处理温度应选在低于再结晶温度和高于沉积温度。在再结晶中晶粒大小容易达到镀层厚度尺寸，以致于脆化的化合物同晶界一起迁移出镀层。相反，通过按本发明的表面镀层的热处理温度的选择，将保证晶界的最优脆化，这在制造电池槽时特别有优点。此外还叙述了按本发明生产的薄板和相应的电池槽。

The dianhydrides of pyromellitic acid, azobenzene - 3,3<SP>1</SP>,4,4<SP>1</SP>- tetracarboxylic acid and azoxybenzene - 3,3<SP>1</SP>,4,4<SP>1</SP> - tetracarboxylic acid are purified by this process. The invention also comprises an equimolecular complex of dioxane and an aromatic dianhydride of the above formula.

Abstract: 1,227,032. Non woven fabric, nap forming apparatus. KAHLER & CO. I/S. 14 June, 1968 [15 June, 1967], No. 28393/68. Headings D1N and D1R. Mineral wool fibres delivered by device 2 are transported in an air stream through chamber 5 and are collected in endless sheet form on a moving conveyor screen 19 which forms at least a substantial part of the end wall of the chamber, and means for withdrawing air through the screen at a rate that can be selectively Controlled across the area of the screen. As shown there are number of separate, but adjacent, suction chambers 31-34 which can be under the action of different suction forces. The varying suction may be obtained by providing each chamber with its own evacuator, or by regulation the suction effect in each chamber from a common evacuator by draft control means. Thus, variation in the thickness or density of the fibres sheet settled on the conveyor above a certain zone is not transmitted to other zones, and consequently no whirls are formed in zones 8 or 9 of the chamber. Coarser fibres may settle, being removed from the chamber through gaps between rollers 12-16 and carried away by worm 18. The conveyor 19 may be the surface of a drum. The fibres may be sprayed with adhesive on leaving device 2.

Abstract: 1,230,828. Plasma jet nozzles. BRITISH OXYGEN CO. Ltd. 29 Out., 1969 [29 Oct., 1968], No. 51223/68. Heading H5H. In a plasma jet nozzle for conversion of a conventional arc welding torch or incorporation in a plasma torch which has two coaxial cylindrical fluid coolant passages divided by a common wall 10, the outer passage being in communication at one end with a coolant outlet (not shown), the inner passage being in communication at the adjacent end with a coolant inlet 37, and the two passages being in communication with each other at the opposite end, means e.g. angularly-spaced axially extending passages 34, are provided for directing the incoming coolant into the inner passage in the form of several angularly-spaced jets. The inlet 37 is connected to passages 34 by a manifold chamber 36 and the outlet to the outer passage by a manifold chamber 38. A replaceable annular anode 24 is brazed or soldered to a thinwalled support 22, the anode 24, support 22 and wall 10 defining the coaxial passages. Coolant hoses which also act as current supply leads are connected either to body 4 or collar 14. The nozzle is internally screw threaded at 6 for connection to a conventional welding torch.
