  • Patent number: 10695869
    Abstract: A process to produce a workpiece surface or a groove inner surface on a rod-shaped, especially cylindrical workpiece. From the workpiece, a rotary tool is supposed to be produced. The material removal is done using laser beam pulses, which are directed through a deflection device onto points of incidence within a pulse area with a specified outside contour on the workpiece. Multiple machine axis drives position the workpiece and the deflection device relative to one another so that the pulse area is oriented essentially at right angles to the emission direction of the laser beam pulses and at right angles to the section of the tool surface that has already been produced and that borders the pulse area. While the material is being removed, the at least one machine axis drive moves the pulse area relative to the workpiece along a specified path of motion while maintaining the orientation.

  • Patent number: 10360245
    Abstract: A system, a method, and a computer program product for deriving target attribute values based on source attributes defined by a hierarchical data mode are disclosed. An attribute value derivation function to change a target attribute data value corresponding to a source attribute stored in a hierarchical data model and an instruction corresponding to the source attribute are provided. The attribute value derivation function is defined by an attribute value derivation header containing metadata describing hierarchical data model and an attribute value derivation instruction for deriving the target attribute based on the source attribute. Using the attribute value derivation function, a target attribute data value is derived. A user interface is generated to display the derived target attribute data value.

  • Patent number: 5836915
    Abstract: The invention concerns an implantable infusion pump for dosed emission of medicines into the human body comprising a pump chamber formed by an upper chamber portion (3) and a lower chamber portion (2), whereby said pump chamber is divided by a flexible membrane (6) into a pressure chamber (8) and a medicine reservoir (7). Refill apertures (12, 14) covered by septa (13, 15) are further provided. The septa (13, 15) are hermetically clamped by holders (4, 5). According to the invention, catch connections are used as main connections (31, 32, 33) and as ancillary connections (34, 35) for the connection of the pump components (2, 3, 4, 5), whereby the main connections (31, 32, 33) substantially support the interior pressure strain generated under normal operating load and the locked ancillary connections (34, 35) are hereby not or only nimimally brought into operation due to respective arrangement and dimensioning of the catch members.

  • Patent number: 5814019
    Abstract: The invention refers to an implantable infusion pump for the dosed administration of medication into the human body comprising a pump chamber which is formed by a lower chamber part and an upper chamber part connected thereto, whereby the pumping chamber is divided into two subchambers by a gas impermeable flexible partition and provided as a reservoir for medicinal solutions, the upper chamber part has a refilling opening which is sealed by at least a pierceable septum and the reservoir for medicinal solutions is connected to an outlet catheter via an outlet opening and possibly an outlet reduction arrangement, and the second subchamber is delimited by the lower chamber part and the flexible partition to serve as a pressure chamber to accommodate a propellant, whereby the gas impermeable partition is a convex metal foil following the contour of the inner form of the upper part of the chamber. This metal foil may be covered on one or both sides with a polymer support film.

  • Patent number: 5611834
    Abstract: The invention is directed to a method for controlling the free deformation of thermoplastic material in an automated process for processing the material to form articles. These articles are especially ampules, small bottles and the like produced from glass tubes. In this method, in order to obtain a high dimensional accuracy of the article, a corrective action is carried out by applying heat to the starting material in the deformation region in the heating phase. This corrective action takes place in dependence on a desired-value/actual-value comparison of the deformation of a workpiece achieved in a predetermined working step. In order to exclude interference influences in the development of the deformation, the measurement of the deformation achieved, the desired-value/actual-value comparison and the corrective action are carried out in situ on one and the same workpiece during shaping of the deformation in the heating phase.

  • Patent number: 5295505
    Abstract: An apparatus for preparing a medicinal solution, in particular dialysis solution, from pulverulent concentrate and water comprises a water source (12) from which a first conduit (14) is led to a container which contains the powder and from which a second conduit (20) into which a first measuring cell (22) and a concentrate pump (24) are connected leads to a mixing point (28). Said mixing point (28) is located in a third conduit (26) which leads from the water source to a consumer; downstream of the mixing point (28) a second measuring cell (30) is provided for monitoring the composition of the finished dialysis solution. Since the two measuring cells (22) and (30) lie in different conduits in which solutions of different composition are conveyed, there is no possibility whatever of confusions between concentrates of the same initial conductivity but different final conductivity after dilution with water.

  • Patent number: 5101474
    Abstract: A control system for a printing press in which a central computer is interfaced to a plurality of printing units through peripheral units located near the press units. The central unit utilizes digital signals to address particular peripheral units and to select control functions at the selected peripheral unit. The controlled functions in the press units provide analog feedback signals which are to be sensed by the central computer. A multi-function bus comprising both analog and digital sections couples the central computer to the peripheral units. The integrity of the analog feedback signals on the bus is maintained by assuring that the digital signals on the bus are maintained in a quasi-steady condition during intervals when the central computer is evaluating analog feedback signals on the analog section of the bus.

  • Patent number: 4977832
    Abstract: A system (and related method) for coordinating electronic zonal control of a printing press to a hard copy image of the printed form. The system supports a hard copy image in register with an optical source which projects an optical mark onto the image. The optical mark is traversed to selected points on the image. The zonal control information is stored in electronic memory means and can be displayed on an electronic display. Neither the electronic display nor the electronic memory have means for storing the actual image pattern. The electronic display has means for displaying a cursor and traversing the cursor across the displayed zone-by-zone information. The system provides means for translating coordinate information from the optical mark projected onto the hard copy image and controlling the cursor position on the electric display so as to correlate image positions from the hard copy with control zone information in the electronic display.

  • Patent number: 4977831
    Abstract: A system and a method for making fountain adjustments in a printing press. A press control panel has a plurality of key pairs for bidirectionally controlling associated fountain adjusters, and the system provides for zonal adjustment by defining zones which include a plurality of fountain adjusters and simultaneously adjusting all of the adjusters in a defined zone. A zone definition begins by detection of simultaneous actuation of both keys in a pair, and a zone is defined by actuation of a further key, the zone encompassing all adjusters lying between the actuated key pair and the further key. After definition of a zone, all of the adjusters in a zone are controlled by operation of one or two keys in the zone. Flexibility is provided to adjust all adjusters in the same direction and by the same amount, or to interpolate adjustments between adjusters.
