A processing apparatus for container blanks, with a machine bed, a feed device for feeding container blanks, a discharge device for removal of container blanks, a rotatably mounted rotary worktable with several locating devices designed for conveyance of container blanks along a circular orbit section shaped conveyance path, wherein the conveyance path determines a first circle segment shaped surface section, several operating devices lying opposite the rotary worktable in the radial direction, and at least one conveyor designed for conveyance of components of container blanks and/or for container blanks along a conveyor section between a component mounting and an assigned operating device. The component mounting of the conveyor is located in a second circle segment shaped surface section, which supplements the first surface section determined by the circular orbit section shaped conveyance path to make a full circle.
摘要:
A device for laser processing, in which the device includes: a laser including a resonator, the resonator being configured to generate a laser beam with a predetermined caustic during operation of the device; and an optical element to transform a laser beam generated by the resonator into a transformed laser beam having an annular intensity distribution in a plane perpendicular to a propagation direction of the transformed laser beam during operation of the device, in which the annular intensity distribution extends along the propagation direction of the transformed laser beam, and has, at a minimum diameter of a caustic of the transformed laser beam, a beam radius and a ring width corresponding to 50% of a maximum beam intensity in a radial direction of the transformed laser beam, and a ratio of the ring width to the beam radius is less than 0.6.
摘要:
An interior fitting for a vehicle, particularly for a motor vehicle, comprises a supporting body, which is provided, at least in areas, with a sensor-functional planar structure and with a covering layer that is located on the side facing the interior. Different output signals can be generated by means of the planar structure according to the location of action thereupon. According to the invention, the covering layer is flexibly designed and completely covers the sensor-functional planar structure.

To improve the reliability of a process for determining the position of a body part in which bone screws are screwed into the bone of the body part in question, each bone screw is provided with a radiation emitter or radiation receiver. A number of fixed receivers or emitters are used as appropriate to receive radiation from the bone screw transmitters or direct radiation towards the bone screw receivers. The radiation direction and/or radiation propagation time and/or radiation field strength or frequency is used to determine the position of each radiation emitter or receiver. A system for determining position based on this procedure and bone screws which can be used therefor are also disclosed.

摘要:
Apparatus for heating and ventilating vehicle compartments. For temperature control, two parallel ducts are provided. A heat exchanger is located in only one of the ducts. A separate blower is associated with each of the ducts, whereby the speed of both blowers is adjustable simultaneously, and inversely proportional, via an actuating element. A mixture of cold and warm air is possible in this manner within the mixing chamber, whereby a sensitive temperature control can be obtained.
