Abstract: Process for preparing and treating a chromium-containing catalyst so that when the catalyst is activated the risk of explosion is substantially reduced. The catalyst comprises a complex of chromium and optionally other transition metal complexes reacted with one or more organometallic compounds of a metal of group II or III of the periodic table, which metal contains hydrocarbyl groups of 1-20 carbon atoms. The reaction product is applied to an inert inorganic support to form the catalyst component which is deactivated by treatment with oxygen or an alcohol to modify or replace residual hydrocarbyl groups. The catalyst component may be activated to form the catalyst by heating in the range 200-1200<sup>0</sup>C. The catalyst is used to catalyze a polimerization of alpha-olefins.

Abstract: Three paperboard webs are glued to one another with as little expenditure of energy as possible. After leaving the gluing apparatus, the finished sheets cut to size are ready for shipment. The middle paperboard web is passed through between two steel rolls which apply glue homogeneously to both sides of the web. High linear pressure is produced in the region of the generatrices of the steel rolls respectively touching the web. Such pressure is necessary in order that a highly viscous polymeric synthetic or natural adhesive, preferably with a solids content of more than 50%, can be used. No special drying facilities are needed, and the water-soluble glue allows recycling without problems.

Abstract: Structural assembly, more particularly for a shower partition, comprising a door support in the form of a profiled rail having, in an outer face thereof, a first channel, of which one side flange forms a groove, and a facing panel mounted in this first channel. The facing panel is held in the first channel by a connecting element fitting in the groove. Existing arrangements of this type are relatively wide, of correspondingly large structural volume, and of high material costs. In order to obtain a structurally simple and inexpensive connection between the facing panel and the profiled rail, it is proposed that the panel be provided with a longitudinal second channel which opens towards the groove of the first channel. The connecting element engages partly in the second channel and partly in the groove.

Granted: 1986-11-20
Abstract: A pivot pin assembly is disclosed which eliminates the need for a high pre-load torque to be applied in order to fix a friction-reducing element relative to the pivot pin. The pivot pin assembly includes a pivot pin having a shoulder formed on a central cylindrical portion thereof which is received in the bores of a forked member and in the bore of an intermediate member located therebetween. The pivot pin, has a conical surface at one end and is held fast in the bore of the other forked member by a collet which also has a tapered surface. The tapered surfaces of both the pin and the collet are mateable with the surfaces of the bores in the forked members as the collet is physically bolted to the pivot pin. A friction reducing element, having an inner and an outer race, is positioned about the central portion of the pivot pin such that the outer race is press-fitted into the bore of the intermediate member while the inner race is slidably received on the pivot pin and abuts against the aforementioned shoulder. An axial force is applied to the inner race by a compression spring which is positioned about the periphery of the pivot pin between the collet and the friction reducing element. The spring takes up slack between the collet and the pivot pin shoulder such that the conical surfaces can tightly interact. The spring also permits the friction reducing element to be held fixed relative to the pivot pin without requiring a high pre-load torque to be applied to the attaching bolt.

Abstract: A centrifugal grinding mill including a grinding chamber of substantially circular cross-section with respect to an axis of symmetry and constrained to have nutating motion about a relatively stationary axis, a support for supporting the grinding chamber, a feed passage in communication with the grinding chamber, a driving assembly for driving the grinding chamber about the relatively stationary axis, and a constraint assembly for determining the form of nutating motion of the axis symmetry of the grinding chamber. The nutating motion of the grinding chamber during operation of the grinding mill causes a grinding charge carried in the grinding chamber to dilate and perform a tumbling motion within the grinding chamber. Further, the grinding chamber has a surface configured to exert pressure on the grinding charge so as to limit its dilation and provide effective containment of the grinding charge.
