Abstract: A portal milling machine has an elongated machine bed (10), the longitudinal direction of which defines an X-direction (2) (machine longitudinal direction). Furthermore, the portal milling machine is provided with a portal (20) which is arranged at right angles to the X-direction and has an elongated plan form, the longitudinal direction of which defines a Y-direction (4) (portal longitudinal direction). A milling unit (50) is arranged on the portal (20) so as to be movable in a translatory manner in a first direction and a second direction transversely to the X-direction (2), and a linear guide (14, 16) which leads through the portal in the X-direction (2) and is intended for a slide (30) carrying a work mounting device (32) and movable in the X-direction (2) is attached to the machine bed (10). In plan form, a part of the machine bed (10) projects beyond the portal (20) in the X-direction (2) at least on one side.

Abstract: The invention relates to improved processes for the biosynthesis of vitamin E. These processes comprise inhibiting the breakdown of homogentisate via maleyl acetoacetate and fumaryl acetoacetate to give fumarate and acetoacetate. Also in accordance with the invention is the combination of this inhibition with processes which increase the supply of homogentisate, or which promote the conversion of homogentisate into vitamin E.

Abstract: A camshaft controller (10), in particular for use in an induction manifold system for a multi-cylinder internal combustion engine, including an induction distributor (11) with individual induction pipes (16 to 19) which are disposed adjacent one another and terminate in a flange. The camshaft controller (10) is disposed in a longitudinal bore in the individual induction pipes (16 to 19) and serves to open and close the induction pipes. Associated with each individual induction pipe is a sealing element (43 to 50) which is secured to the camshaft controller (10).

Abstract: With the advent of multimedia in computer systems, it is necessary to integrate audio and video in the computer as data types equivalent to text and graphics. For this purpose, provision is made of program modules which carry out different tasks. In order to define the properties of each audio/video device, an endpoint module is generated for each audio/video device and then forms the interface to the remaining modules. When a data packet is to be transmitted from one device to another device, an event or a request is generated, which is evaluated by an event module, which then selects the corresponding endpoint modules and establishes a logical link between these endpoint modules. The data packet is controlled by means of a data module, which also initiates the storage of the data packet. Following termination of the transmission of the data packet, the event module searches for further requests which can, for example, be held in a queue in a waiting loop.

Abstract: A method for the manufacture of filters in which a filter material in the rm of a continuous web is pre-embossed, perforated with a laser beam, and then pleated.

A golf putter 10 (FIGS. 1 and 2) including an elongated shaft 11, a hand grip 13 on one end, and an opening 15 at the other end thereof, is disclosed. A hollow insert 17 is fixedly attached (via adhesive bonding, soldering, or the like) within the open end 15 of shaft 11. The interior open area of insert 17 has a cross-sectional area in the form of a square, hexagon, octagon, keyway, or other angular surface shape and serves to receive a shank 19 of putter head 20 therein. The angular exterior surface of shank 19 is the male counterpart of the female opening of insert 17 and is adapted to snugly fit therein. Screws 25, 27 are threadedly inserted through transverse spaced bores formed through the club shaft 11, insert 17 and shank 19 to releasably attach putter head 20 to shaft 11.

Abstract: Machine tool comprising a spindlehead which can be swung into several operating positions.

Abstract: The invention relates to a device for clamping of a machine table or a pallet on a machine bed or frame, whereby the machine table rests at several bearing points on support pins or the like which are arranged on the machine frame. The clamping force is applied by one single, central clamping device, which engages approximately in the center of a plate, which in turn is coupled in the area of the bearing points on the underside of the machine table. The plate serves to transmit the centrally applied tensioning force into the area of the support of the machine table in order to avoid bending or distortion to the machine table.

Abstract: The invention relates to a device for changing of tools into the work spindle of a machine tool. It includes a two-arm changing arm, the axis of rotation of which is positioned at an angle of 45.degree. with respect to the work spindle, and the gripping ends of which are angled each at 45.degree. toward the axis of rotation. The tools are inserted into the changing arm with the ends, which are to be inserted into the spindle, pointing away from the axis of rotation, so that, in particular when using long tools, a smaller flight circle and thus a smaller collision free space, which is to be kept free, results. Therefore, the device is particularly suited for machine tools with two spindles. The entire changing arm with its support, which permits the change rotation and the pulling out and inserting movement of the tool out of and into the spindles, is pivotal about an axis which extends perpendicularly with respect to the plane which is defined by the spindles.

Abstract: A tool-changing mechanism for machine tools of the kind in which tools can be inserted into a spindle. A tool magazine receives several tools and a double-ended tool-changing arm is provided on each of its two ends with gripping mechanisms. The tool-changing arm is rotatable about an axis of rotation which is parallel to the spindle axis and the tool-changing arm can be moved along the direction of its axis of rotation. The tool-changing arm can also be pivoted, between a working position and a rest position, about a pivot axis which is parallel to its axis of rotation.
