The system has a piezoelectric transducer including a quartz tuning fork has two pairs of electrodes (3,4) (5,6) which are driven (15) to cause a primary vibration of flexion between the two branches of the tuning fork in a direction parallel to their principal faces. The primary vibration causes a secondary vibration which is perpendicular to the principal faces of tuning fork and has one compone...

A system and method for generating specifications, estimates and orders for the manufacture of custom items such as business forms is provided which stores estimate data at a central location, e.g., a corporate office (10), for access by sales representatives at remote sales sites (12). A sales representative creates an item specification for a form to be manufactured and electronically transmits ...

A piston for operation of a hydraulic brake produced in a cold-forming process, for example a deep-drawing process, has a relatively thin outer wall (4) which has a cross-section smaller than the desired contact surface (A) for the contact of the piston (1) with the brake lining. According to the invention, it is proposed to roll the edge (3) of the pot-shaped piston (1) inwards and then to machin...

A stability control agent composition for foamable polyolefin compositions comprising at least one compound that is a partial ester of fatty acid with polyol, and at least one compound selected from the group consisting of higher alkyl amines, fatty acid amides and/or complete esters of higher fatty acids.

To simplify handling of optofiber ribbons, there is provided a component for cross-connecting optofibers between different fiber ribbons, where the component pre se cross-connects optofibers between different fiber ribbons connected to the component. The component enables a fiber ribbon structure to be retained and undivided, even after cross-connecting or otherwise reorganizing the optofibers in ...
