Abstract: The invention relates to an arrangement to strip unwanted matter from belt bands (2) in conveyor belt installations in the region of a driving and/or direction-changing roller (3) of the belt band, comprising a systems support (4) which is attached to a supporting structure for the belt band and on which at least one stripping member (5) is arranged. Each stripping member comprising a scraper blade (17; 48) which is attached to a support (16; 49), which scraper blade, in the ready-to-operate position, abuts against the belt band (2) in a peeling fashion. The stripping member comprises a torsion spring joint (25) on which the blade support is guided in a spring-loaded manner and so as to pivot about a horizontal axis such that, when the scraper blade encounters obstacles which rigidly adhere to the belt band, it can pivot away and subsequently again pivot back into the working position on the belt band. In this regard, the blade support (16; 49) is pivotally supported by a pivot bearing (20a; 50) having a limited pivot angle, such that the scraper blade (17; 48) which abuts against the belt band (2) can adjust to changes in inclination of the belt band (2) in the immediate contact region of the scraper blade (17; 48) by pivoting automatically.      The torsion spring joint (25) is attached to a plug-in means (26) which is arranged in a holding means (27a, 27b) which is attached to the systems support (4). The longitudinal axis (28) of the plug-in means (26) intersects the belt band (2) at a point which, in the direction of rotation of the roller (3), is disposed upstream of the contact line (S) of the scraper blade (17; 48).

Title: Label inserting method and apparatus
Inventor: DOBLER WALTER
IPC: B29C51/16
Filed: 1995-06-27
Granted: 2001-03-27
Abstract: The present invention relates to a method for providing at least one insertion label on a tool of a machine, the insertion label being insertable into a mold half of a tool of a plastics processing machine, in particular injection molding machine or deep-drawing machine. In this method insertion labels are punched out of label web material by means of a punching device consisting essentially of a punching plate and a cutting tool. The insertion labels are transferred by a carrier, which belongs to the punching device, to the tool of the machine and are discharged for insertion thereinto. So far a great problem has consisted in performing such a transfer in such a manner that the insertion label is positioned in a sufficiently precise manner without creases. This problem is overcome in that after the punching operation the insertion labels are held by the punching plate which is movable substantially in a direction transverse to the punching direction and formed as a carrier, and are transferred to the tool of the machine. Furthermore, the present invention relates to an apparatus for performing the method.

Abstract: A method and computer product for rendering real-time three-dimensional images on a display based on view manipulation of prestored depth images in a global coordinate space. First, a layered depth image is generated from multiple depth images based on a predetermined display viewpoint. If the determined viewpoint is within a predetermined threshold of the layered depth image, the generated layered depth image is warped based on the determined display viewpoint, pixels from the layered depth image are splatted onto the warped image, and an output image is generated and displayed based on the splat pixels. If the determined viewpoint is outside the predetermined threshold of the previously generated layered depth image, a next closest layered depth image is generated. If the next closest layered depth image is not fully generated, the previously generated layered depth image is used to generate an output image. If the next closest layered depth image is fully generated, the process is repeated for the generated next closest layered depth image.
