A linear module has a rail with a longitudinal axis, a table part, and at least one linear guide device; the at least one linear guide device has a main part embodied so that it is integrally joined to the table part, two end caps, and at least one endless roller element circuit. The length of the table part measured in the direction of the longitudinal axis is greater than that of the linear guide device and at least one end cap is accommodated in a recess of the table part; the recess is open toward the underside of the table part and is delimited by the top surface of the table part, by at least one side wall of the table part, and by the main part of the linear guide device.
摘要:
The invention relates to products, containing a solid biocide and a composite material (11) for the absorption of contaminants and the release of active ingredients as a composite preparation for the simultaneous, separate or programmed sequential application on sterilisation and long-term conservation of a liquid (6) for purification. According to the invention, the activity of the solid biocide can be maintained by additionally treating the liquid (6) with the composite material (11), which absorbs (5.1, 5.2) from which the liquid and/or contaminants simultaneously releases active ingredients (13.1, 13.2) for sterilising and/or reducing the contaminants (5.1, 5.2) in the liquid (6). The products and the method are particularly suitable for sterilising and long-term conservation of water/oil emulsions which are contaminated by sulphur-containing compounds.
摘要:
A linear guiding unit comprises a guide housing (10). Inside the guide housing (10) there are provided linear ball bearings by which a carriage (40) is guided. Moreover, a pneumatic drive (56) is accommodated within the guide housing (10). The pneumatic drive comprises a cylinder cavity (58) inside the guide housing (10). The cylinder cavity (58) accommodates a piston (60). The piston (60) is movable along the cylinder cavity (58). The piston (60) is connected with the carriage (40) by a flexible rope (74). This flexible rope is sealingly passed through cover walls (66) of the cylinder cavity (58). The rope is deviated outside the cylinder cavity (58) and is fixed to the carriage (40). A cover belt (90) different from the rope covers a longitudinal opening (31) of the guide housing (10) through which the carriage can be connected with an object for common axial movement.
