摘要:
A dressing tool (100, 200, 300, 400, 500) for conditioning of grinding bodies, especially ceramically bonded grinding bodies, the dressing tool (100, 200, 300, 400, 500) comprising a base body which bears a self-supporting function coating (120, 220, 320, 420, 520) which defines the working region of the dressing tool, the function coating (120, 220, 320, 420, 520) comprising a porous bonding matrix (121, 221, 321, 421, 521) which is uniformly penetrated with grains of hard material (122, 222, 322, 422, 522), is characterized in that in the porous bonding matrix (121, 221, 321, 421, 521) there are additionally embedded reinforcing elements (130, 230, 330, 430, 530) of a hard material for stabilizing the function coating (120, 220, 320, 420, 520).
摘要:
The invention relates to a deflecting arrangement having a first deflecting element (34) for deflecting conveyable-article carriers (7), and having a second deflecting element (50) for deflecting an endless drive belt (9) for driving the conveyable-article carriers (7) in an overhead conveying arrangement, the deflecting arrangement (3′) forming one of two deflecting stations around which the endless drive belt (9), which is driven for movement, runs as a loop, and the endless drive belt (9) being guided along the route region from deflecting station to deflecting station for carrying along conveyable-article carriers along the conveying route of the overhead conveying arrangement. For the purpose of adjusting the tensioning of the drive belt (9), the second deflecting element (50) is arranged on a mount (30) such that it can be displaced relative to the first deflecting element (34).

The present invention provides means and methods of transforming plant cells, seeds, tissues or whole plants in order to yield transformants capable of expressing all enzymes of the carotenoid biosynthesis pathway that are essential for the targeted host plant to accumulate carotenes and/or xanthophylls of interest. The present invention also provides DNA molecules designed to be suitable for carrying out the method of the invention, and plasmids or vector systems comprising said molecules. Furthermore, the present invention provides transgenic plant cells, seeds, tissues and whole plants that display an improved nutritional quality and contain such DNA molecules and/or that have been generated by use of the methods of the present invention.
摘要:
The invention proposes a conveying apparatus with a three-dimensionally movable receiving conveyor for receiving conveyable-article carriers (3) from a suspended conveyor in which the conveyable-article carriers (3) are guided on a running-roller guide profile for movement along a first conveying section (5) and are supported in a suspended manner on own running rollers (29). The receiving conveyor has a series of receiving elements (17) which are arranged one after the other on a drive chain (15), are moved by the chain (15) along a second conveying section (9) and are intended for the conveyable-article carriers (3), it being the case that, at a receiving location, the conveying sections (5, 9) run closely adjacent, and the receiving elements (17) are guided such that they execute a lifting movement in order for conveyable-article carriers (3), which are fed to the receiving location (49) from the suspended conveying apparatus in each case, to be engaged at engagement means (29), which project from said conveyable-article carriers, for the purpose of being carried along the second conveying section (9).

摘要:
A space-dividing wall panel has glass panels mounted on opposite faces of the wall panel to permit viewing therethrough. Each glass panel is defined by a sheet of glass and edge rails extending about the periphery of the glass. The edge rails include fixing channels on opposite sides thereof which are press-fit onto respective edges of the glass without the use of a resilient gasket within the fixing channel.
