Abstract: Based on an indexable tip (1), which serves to bevel a cylindrical or conical milling head (12) and which has both ground cutting edges (7) as well as a bore hole (8) that extends from the free surface (2) to the supporting surface (3) of the indexable tip while provided for the passage of a fastening means (fixed plate) that has a head, and based on the ability to be reversed by turning around the indexable tip about the axis of the bore hole, the invention provides that the indexable tip also has the ability to be reversed by turning around which involves interchanging the prior supporting surface and free surface, both of these surfaces having a width between the cutting edges of greater than 5.5 mm. The ability to be reversed by turning around signifies that the indexable tip widens again from its thickness in the middle up to the supporting surface in order to form at least two other cutting edges.

Abstract: A coupling mechanism for connecting a catheter to a medical infusion line includes a catheter hub arranged on the catheter and a coupling piece arranged at an end of the medical infusion line for connecting with the catheter hub. A pin is axially aligned in the insertion direction of the coupling piece or a sleeve configured for receiving the pin and a locking wedge aligned parallel with the axial extension of the pin or a wedge receptacle for a form-fitting connection of the locking wedge. The wedge receptacle is defined by hinged positive locking elements which are able to move apart from each other. Lever arms are arranged at a distance from each other on the catheter hub or the coupling piece. They interact with the positive locking elements when the coupling mechanism is coupled such that the positive locking elements are spread and the locking wedge is consequently released when the lever arms are actuated.

Abstract: The wafer scanning device causes a wafer to scan in a vacuum area and includes a holder 10 to hold a wafer, a ball screw 20 to move the holder 10 to scan, a motor 50 to drive the ball screw 20 and an integrally formed support frame 60. While the holder 10 and the ball screw 20 are installed in the vacuum area, a transmission mechanism offset from the line of travel of the ball screw 20 and the motor 50 are installed in the atmosphere. Thus the wafer scanning device improves responsiveness with respect to the scanning speed control, enhances the uniformity of the scanning speed, has the motor or the like arranged properly and achieves the tilt of a wafer in a most preferable manner.

Abstract: The invention relates to an autoclave for medical appliances and instruments with a chamber (13) in which the appliances to be sterilized are located, with a steam generator (5) and a condensate collector (11), whereby the steam generator is connected with the chamber (13) by a steam pipe (9) and the condensate collector (11) is connected with the chamber (13) by a feed pipe (35) of the condensate. The invention is characterized in that the condensate collector (11) is positioned above the steam generator (5), staggered with respect to the steam generator (5), by positioning a check valve (41) between the condensate collector (11) and the steam generator (5) and by providing a check valve (39) at the mouth of the feed pipe (35) of the condensate to the condensate collector (11).

Abstract: The invention relates to a method for turning and reorienting the displacement direction of strips (1), especially of a thin hot strip. The strip can be turned about any angle by means of at least one deflection roller, with roller banks (5) which are arranged on the circumference of the deflection roller, and which respectively comprise a plurality of individual rollers. Plastic and elastic deformations are avoided due to the fact that the strip is supported at various points by the individual rollers of successive roller banks (5). The invention also relates to a device for carrying out the method. Said device enables the roller banks placed one after the other in the strip deflection direction to be staggered in relation to each other in such a way that the contact surfaces of their rollers with the strip are staggered from bank to bank, by one roller width (11,12).

To this end, the invention provides that thin slab thicknesses of approximately 50 mm are used for easily shapeable material, that the first of seven stands is driven or executes only a smoothing pass, the slab is de-scaled in front of and behind the first stand, and that the second to seventh stand effects the reduction in thickness to less than 1 mm.

Abstract: A transport and storage container for liquids has a support frame of electrically conducting metal or plastic material. An inner plastic container is positioned on the support frame and has an electrically conducting exterior layer for electrically grounding the outer surface of the inner container. The inner container has an outlet socket with an electrically conducting outer layer arranged near the bottom. The outlet socket is formed as a unitary part of the inner container and has an outer cylindrical end drawn inwardly to form an inner ring with an annular electrically conducting inner layer that is in contact with liquid in the inner container for electrically grounding the interior of the inner container. The electrically conducting inner and outer layers of the outlet socket and the external container layer form a homogenous electrically conducting layer providing inner and outer electric grounding.
