Patent EP-0368644-A1 (EP)
Inventor: CHANG MAIN
IPC: C08F4/6392
Filed: 1989-11-08
Abstract: This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 6 to about 20 per cent by weight adsorbed water as the catalyst support material. It has been found that such silica gel may be safely added to a solution, of trialkylaluminum to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the majority of the alumoxane component requirement of the catalyst system. An alkylalumoxane coated silica gel is formed to which a trimethylaluminum treated metallocene may be added and the resulting material dried to free-flowing powder. The dry free flowing powder may then be used as a supported metallocene alumoxane catalyst complex for gas phase or liquid phase polymerization of olefins. The supported catalyst produced by such procedure has an activity at least comparable to a catalyst of similar composition which is produced exclusively with trimethylaluminum as the alumoxane forming aluminum alkyl.

Abstract: In a pushbutton arrangement, the electrical contact is made directly to the conductor tracks (6) of a printed circuit board (1) by a snap-action disc (5), the snap-action disc (5) being mounted in a cutout in the spacer (2) and being protected by a covering sheet (3).   In order to avoid excessive loads on the covering sheet (3) and the snap-action disc (5), the spacer (2) is constructed as a printed circuit board with a thickness of more than 1 mm to provide space for a transparent protective cap (4) which completely covers, on the one hand, the snap-action disc (5), which is anchored by means of at least two projecting lugs (11) in cutouts (10) in the printed circuit board (1) and which, on the other hand, limits the deformation of the covering sheet (3) and of the snap-action disc (5). Protective cap (4) and covering sheet (3) are illuminated through cutouts (8) on the snap-action disc (5) and through a cutout (7) in the printed circuit board (1). <IMAGE>

Inventor: HERDZINA FRANK J
IPC: B21D51/38
Filed: 1989-01-09
Abstract: A press for converting work pieces into finished parts has an elongated bolster (20) mounted on a press bed (14). The bolster (20) supports columns (24) on which a ram (36) is slidable. The bolster (20) also supports the lower die shoe (42) of the press tooling. A conveyor (56) or transfer system mounted on the bolster (20) carries work pieces into and out of the area of the tooling. The bolster (20) is a unitary piece which integrates support of the die shoe (42), columns (24) and conveyor (56) to assure proper cooperation and alignment among them. A pivotable carrier (58) mounts a feed mechanism (136) for feeding a stock strip (140) into the tooling. Power to the feed mechanism (136) is supplied through a shaft (128) which is coaxial with the hinge line (124) of the carrier (58), so that the carrier (58) can be swung away from the tooling for service access without requiring disconnection of the power supply. A traveling vacuum box (44) on the lower die shoe (42) supports the conveyor (56) for vertical as well as longitudinal motion, and retains the work pieces on the conveyor (56). <IMAGE>

Abstract: In a pneumatic tire having a unidirectional tread pattern formed with plural circumferential grooves and plural transverse grooves (2) arranged so as to intersect the circumferential grooves at an acute inclination angle into a herringbone pattern along a tire rotative direction, the circumferential grooves are formed in such a way that bottoms (BE₁, BE₀) of the circumferential grooves are offset axially outwardly from the groove center along the tire reverse rotative direction and axially inwardly along the tire rotative direction, between two circumferential groove ends (E₀, E₁) intersected by two adjacent transverse grooves. Therefore, water on the tire tread can be drained not only in the tire circumferential direction but also in the tire transverse direction, effectively.

Abstract: An ultrasonic air-in-line detection system for use in detecting air bubbles in the fluid line (306) of a disposable cassette mounted on a main pump unit which can accurately detect air bubbles in any type of fluid, whether clear or opaque. The system uses a windowing technique to determine when a threshold amount of air bubbles in a predetermined voulime of material pumped occurs, with the alarm being sounded only when this threshold amount of air bubbles in present in the window volume. The system of the present invention thus avoids so-called nuisance alarms due to the presence of small isolated air bubbles in the fluid due to the fluid pumped not having degassed.

Abstract: The lattice girder (1) for concrete linings on rock faces has an outer boom member (9) turned towards the rock face (8) and designed as a hollow profile. The inner boom members (16, 17) are composed of round bar steel, and they are connected to the outer boom member (9) by means of bracing elements (13, 14). The hollow profile of the outer boom member (9) having a substantially larger cross-sectional shape affords the lattice girder (1) greater strength with a statically balanced cross-sectional shape, without substantially increasing the spray-shadow formation. As a result, the lattice girder (1) is suitable both for sprayed-concrete linings and as a support for concrete forms to be backfilled by no-fines concrete. <IMAGE>
