Title: Detection of Arsenic Trioxide in Air
IPC: G01N31/22
Filed: 1980-04-02
Abstract: For detecting the presence of arsenic trioxide in air, there is used a closed glass tube (6) having a breakable tip (7,8) at each end. The tube (6) contains a breakable ampoule (1) containing sulphuric acid, a filter (2) impregnated with zinc dust, a layer (3) of granular silica gel, a layer (4) of granular quartz and layer (5) of granular silica gel impregnated with gold chloride. In use, the tips (7,8) of the tube (6) are broken off, and air to be tested is drawn through the tube (6) in the direction of arrow (9), whereby arsenic trioxide in the air is retained on the filter (2). The ampoule (1) is then broken, and the sulphuric acid is drawn into the layer (4) through the filter (2) and the layer (3). The sulphuric acid reacts with the zinc dust to form nascent hydrogen the hydrogen reacts with the arsenic trioxide to produce arsenic hydride and the arsenic hydride reacts with the gold chloride to discolour the layer (5). The extent of discolouration is proportional to the arsenic trioxide content of the air. <IMAGE>

Title: Process for the recovery of zinc and copper values from sulphidic ores
IPC: C22B15/00
Filed: 1981-02-02
Abstract: A process for the recovery of copper and zinc values from copper and zinc containing sulphidic ore includes subjecting ground ore to a flotation operation. An initial copper concentrate is floated in a first flotation step, and the initial copper concentrate is fed to a second flotation step to float a relatively zinc free copper concentrate. Remaining ore from the first flotation step is fed to a third flotation step to float an initial zinc concentrate, and remaining ore from the third flotation step is fed to a fourth flotation step to float a copper and zinc containing material. An intermediate concentrate containing from about 5 to about 25% copper and from about 2 to about 25% zinc, with a total of at least about 12% copper and zinc, is produced by selecting at least the remaining ore from the second flotation step, and a zinc concentrate containing at least about 20% zinc is produced by at least selecting a portion of the initial zinc concentrate.

Title: Stacking heat-exchange fins cut to length from a continuous strip
IPC: B21D43/22
Filed: 1981-10-20
Abstract: Heat-exchange fins 26 are cut to length successively from a continuous strip 10 in which rectangular openings 18 are formed, these openings having tubes inserted therethrough in a completed heat exchanger. A metering drum 31 moves the strip 10 intermittently past a cutting station, and each time the strip is stationary a punch and die set 30 is operated to sever a length of the strip and thereby form a fin 26. At the same time, the punch and die set 30 punch a slot 65 in the fin which opens onto one of the openings 18, thereby forming a T-shaped slot 66 in one end of the fin, while a movable female component of the punch and die set displaces the fin in a direction perpendicular to its general plane and onto a fixed male component 27. In this way, the fins 26 are stacked on the component 27 as they are produced. <IMAGE>

Title: Fricton overload coupling
IPC: A01B71/02
Filed: 1981-10-20
Abstract: A fricton over-load coupling has housing parts 3,12 held together by a plurality of circumferentially spaced axially extending bolts 7 each having a nut at both ends.
