Patent number: 9457430Abstract: The invention relates to a protective device (1) for the laser machining of holes (3) in at least one component (2) by means of a laser beam (5), wherein the protective device (1) is positionable in the beam direction downstream of the beam-exit-side end (8) of a hole (3) to be machined in the component wall (10), in order to protect an adjoining rear space having a component wall (11), opposite the hole (3), of the component (2) from the incident laser beam. The protective device (1) according to the invention is formed from a composite made of a matrix composed of polyether ether ketone plastics material and fibers embedded therein, wherein the fibers are embedded such that, with respect to their particular fiber extending direction, they extend in a criss-cross manner in the plastics material and are distributed at approximately the same density in the volume of the plastics material of the protective device (1).Type: GrantFiled: June 21, 2012Date of Patent: October 4, 2016Assignee: Robert Bosch GmbHInventors: Thorsten Bauer, Ulrich Graf

Patent number: 8714075Abstract: An aerostatic bearing and a linear compressor that includes the aerostatic bearing. In an exemplary embodiment, the aerostatic bearing includes a guide element including holes, and a body structured to move along a surface of the guide element. The holes may include a first section close to the body, of which at least one part area features a cross-sectional surface substantially constant over its entire length which is smaller towards the body than another cross-sectional surface of an area away from the body. A method for producing a hole in an element, using a laser beam, for producing the aerostatic bearing is also disclosed.Type: GrantFiled: October 31, 2008Date of Patent: May 6, 2014Assignee: BSH Bosch und Siemens Hausgerate GmbHInventors: Marco Giacchi, Ulrich Graf, Christian Mayershofer, Jörn Ostrinsky, Jan-Grigor Schubert, Andreas Wolf
