摘要:
A method for manufacturing a Z-directed component for insertion into a mounting hole in a printed circuit board according to one example embodiment includes simultaneously extruding a plurality of materials according to the structure of the Z-directed component to form an extruded object and forming the Z-directed component from the extruded object. In one embodiment, the extruded object is divided into individual Z-directed components. In one embodiment, the timing of extrusion between predetermined sections of one of the materials is varied in order to stagger the sections in the extruded object.

A process for performing a Fischer Tropsch reaction comprising (a) providing syngas to a reactor, said reactor comprising catalyst particles that have been produced by extruding a paste using a die comprising a plurality of channels extending from an inlet to an outlet, wherein from the inlet to the outlet each channel comprises a first section with a helical bore with a non-circular cross-section, and a second section with a cylindrical bore which has a diameter equal or greater than that of the first section, wherein the second section is at least twice as long as a diameter of the first section; (b) providing the following process conditions in the reactor: a temperature from 125 to 350° C., and a pressure from 5 to 150 bar absolute, and a gaseous hourly space velocity from 500 to 10000 Nl/l/h; and (c) removing Fischer Tropsch product from the reactor.
摘要:
The invention relates to an apparatus for the targeted deformation, in particular for the counterbending, of an extruded plastic profile in a wet calibration, characterized by an adjustment apparatus (50) for the targeted, spatial setting of at least one calibrating element (20, 21, 22, 23, 24, 25, 26, 27, 28) in a calibrating system, wherein a predetermined curvature can be applied to the extruded plastic profile (10) during the calibration by the at least one calibrating element (20, 21, 22, 23, 24, 25, 26, 27, 28). What is furthermore described is a corresponding process.

The present invention relates to a railing element, and to a method for the manufacture thereof. A railing element according to the invention comprises a profile body substantially of a plastic composite and a decoration at the surface of the profile body. The method according to the invention comprises the steps of forming a profile body from a plastic composite and arranging a decoration at a surface of the profile body.
摘要:
A method of stamping a rubber sheet member in the annular state on a side face of a body of rotation, wherein: a leading end of a long rubber sheet arranged on a tangent of an annular band on the side face of the body of rotation to be a stamping face of the rubber sheet member is held, and the leading end is transferred onto the annular band and pressed and then, the rubber sheet is stamped onto the annular band by rotating the body of rotation around its central axis while applying a tension to this rubber sheet, after the rotation of the body of rotation is stopped, an unstamped portion of the long rubber sheet is cut off, and the unstamped portion to be the rear end of the rubber sheet on the annular band is pressed onto the annular band to stamp the rubber sheet member.
摘要:
A method of manufacturing a tire having first color characters or lines on at least one side wall part, comprising the steps of stamping a second color side wall rubber and a first color side wall rubber on the side face of a carcass member formed in a toroidal shape by winding, a plurality of turns, a continuous second color rubber ribbon and a continuous first color rubber ribbon thereon, stamping a second color cover rubber on the outsides of the side wall rubbers by winding a rubber sheet whereon one turn in an annular shape, and molding a green tire, whereby the use of a large extruder can be eliminated, the other types of tires can be efficiently manufactured since a size switching can be easily performed, the accuracies of the shape and the dimensions of the members thereof can be increased, the uniformity and the tire balance thereof can be increased, and the sharp profile of the first color characters or lines can be assured, thus eliminating visual problems.
