Title: Method for the preparation of a polymerizing catalyst component, a polymerizing catalyst component prepared by the method and its use
Inventor: GUSTAFSSON BILL
IPC: C08F4/02
Filed: 1991-12-17
Abstract: The invention relates to a process for the preparation of a solid procatalyst composition of catalyst system for the polymerization of olefins wherein a magnesium halide such as magnesium chloride is dissolved and/or suspended into an alkyl ester of a monocarboxylic acid such as ethyl acetate, impregnated to a carrier, treated with an organometallic compound or a silicon compound and thereafter with a transition metal compound. The invention also relates to a procatalyst composition and its use together with a cocatalyst for the polymerization of olefins. The activity has been enhanced according to the invention by the use of a carrier containing hydroxyl groups, which carrier is kept at a temperature of at most about 200 ·C prior to the impregnation so that the hydroxyl groups are retained in the carrier to an essential extent until the impregnation step. The carrier is preferably silica which is treated thermally at 100-200 ·C so that the water present is removed but the hydroxyl groups are retained to a considerable extent. The organometal compound is preferably an aluminumalkyl compound such as triethylaluminum, and the transition metal compound is preferably titanium tetrachloride.

Abstract: -the invention concerns monoclonal antibodies,designated tbp-1, tbp-2 and tbp-6, against the extracellular part of the hu-man 60 k1) TN tumour necrosis [actor receptor (TNF-BP1). These antibodies are suitable for use in highly semsitive immuno-as says for demonstrating the presence of TNF1-BP 1 in body fluids, including urine, and in cell-culture residues. The determination of the TNF-BP1 concentration as the basis for a diagnosis of pathological conditions associated with activation of the TNF re-ceptor system is thus particularly useful if the ~TNF concentration in the organism falls more rapidly than the TNF-BPI con-centration. In addition, tbp-1 and tbp-6 can he used to strengthen the protective action of TNF-BP1 against (~-TNF and/or (.beta.-TNF-

Patent CA-2128086-A1 (CA)
Title: Stripper drums
Inventor: SHELBOURNE KEITH H
IPC: A01D75/18
Filed: 1993-01-12
Abstract: A crop stripper has at least one drum (6a, 6b) with several axially extending series of stripping teeth (8). The drum is rotat-ably in end supports. The tooth roots (26) at the ends of the drum have an edge profile inclined radially away from the adjacent supports to deflect plant stems which contact these profiles during the operation of the stripper away from the supports, so redu-cing the tendency for the stems to become trapped between rotor and support. A  capping (32) on the support overlaps the adja-cent tooth roots to assist this effect. A pair of drums can be arranged end to end with an intermediate support (14) between them and be similarly arranged to deflect plant stems away from the intermediate support. This allows increase of the operating width of the crop stripper while minimizing the risk of blockage from stems trapped between the intermediate support and the drums.
