Patent CH-681622-A5 (CH)
Title: Processing swellable clay adsorbers charged with heavy metals - by desorption of heavy metal e.g. with acid and testing heavy metal adsorption capacity of regenerated clay to indicate reuse or removal from system
Inventor: KRUSE KAI
IPC: B01J20/34
Filed: 1992-04-22
Abstract: To treat swellable clay materials loaded with heavy metals in a waste water treatment system, the adsorbed heavy metals (HM) are desorbed in a first desorption by means of an acid (step 1), which gives a regenerated clay (step 3). The heavy metal soln. is sepd. from the regenerated clay and the regenerated clay is reused for the adsorption of heavy metals (step 5) and its HM-adsorption tested (step 6). If the HM-adsorption capacity is satisfactory, the HM-loaded clay is re-circulated to a further desorption (step 7), whereas if the HM-adsorption capacity is insufficient, the HM-loaded clay is withdrawn from the system for further processing. USE/ADVANTAGE - Process allows the clay to be reused in the process after desorption of the heavy metal until its adsorption capacity is exhausted, at which point it may be subjected to a more rigorous desorption of the heavy metals to give a prod. which can be utilised as a bleaching clay, or it may be converted into a modified bentonite such as an organophilic bentonite which can be used for adsorption of organic substances, thus avoiding the necessity for disposing of clay contaminated with heavy metals.

Title: Device intended to vary the timing setting of a combustion engine
Inventor: CHATELAIN PIERRE
IPC: F16H7/08
Filed: 1982-12-21
Abstract: Two arms (14, 15) are articulated to one another about a pivot (16) integral with the engine (1). A first roller (18) fixed to the arm (15) interacts with the conducting strand (32) of the toothed belt (9), located between the crankshaft pulley (7) and the intake camshaft pulley (5), and a second roller (19) carried by the arm (14) acts on the strand (33) located between the pulley (5) and the pulley (4) of the exhaust valves. The displacement of the rollers (18 and 19) takes place by virtue of a motor (25) driving a threaded rod (28) engaged in a nut (29) mounted pivotably on the arm (14). The angle of opening between the two arms (14 and 15) may be adjusted manually or automatically. The belt (9) is tensioned by a tensioning roller (11). The motor (25) is subjected to a control (31) which is sensitive to the speed of the engine (1). The instants at which the valves are opened and closed can thus be varied without changing the duration of their opening. <IMAGE>

Patent CH-610532-A5 (CH)
Title: Device for coating a belt by means of a sliding-surface pouring head
Inventor: RIDLEY KENNETH ARTHUR
IPC: B05D7/00
Filed: 1975-09-24
Abstract: Coating liquid is introduced onto a sliding surface (2) of the pouring head (1) and falls down as a curtain (9) onto a moving belt (8). By the Coanda effect, the curtain obtains a curved shape at an edge (7). In order to delimit the curtain, rods were hitherto attached at both sides of the edge (7). The edges of the curtain followed these straight rods whilst the centre part of the curtain assumed the curved shape. It was thereby possible for tears to occur in the curtain. Wide (for example 2.5 cm) guide plates (5, 6) permit the edges also to assume the curved shape, so that a tearing of the curtain is avoided. <IMAGE>
