Abstract:
The invention relates to a method for producing a tool-system module, such as a tool having brazed blades (PKD, CBN or hard metal), wherein a cylindrical blank is equipped at an axial end with a conical hollow shaft (HSK), in particular according to DIN 69893. Select functional areas undergo a hardening process. The hardening step is carried out according to the induction hardening method and integrated in the continuous manufacturing line of the tool-system module.
Abstract:
A high pressure fuel pump encompasses at least one delivery chamber and one high pressure outlet. In addition, a pressure limiting valve with a valve that is actuated by a pressure differential is provided that can open from the high pressure outlet to the delivery chamber. On a high pressure side of a valve seat of the pressure limiting valve, it is advantageous that a throttle device is provided, whose free cross section is at most approximately equal to a desired maximum opening cross section of the pressure limiting valve.
Abstract:
A seal ring for a mechanical seal, comprising a base body, a first layer applied to a first face side of a base body, and a second layer applied to a second face side of the base body. At least one of the layers is configured as a slide surface of the seal ring.
Abstract:
The invention relates to a modular automated tool dispenser comprising at least one tool delivery module with at least one tool compartment containing a plurality of tools that are combined to form tool classes and with a plurality of tool conveying devices, each device being associated with one of the tool classes and conveying tools of one class to a tool delivery point. Each tool class is defined by the tool type, tool size and/or the tool weight as a tool parameter. The dispenser also comprises a tool selection device for selecting the desired tool class and the number of tools to be delivered and for activating the tool conveying device that is associated with the selected tool class.
Abstract:
A slide ring seal arrangement comprises a rotationally fixed slide ring (4) and a slide ring (11), which is provided for rotating together with a rotating component, these slide rings each being held in a loose seat and interacting, in, in essence, radially oriented sealing surfaces, which are prestressed with a main prestressing force while in contact with one another. Each slide ring, on its front face that faces away from the sealing surface, is axially supported on a supporting part (14, 17) via an annular bearing surface (16, 20) provided between the respective supporting part and the adjacent front face of the respective slide ring. A load ratio (d12−dH2)/(d12−d22) of =2.0, preferably between 0.8 and 2.0, preferably no greater than between 1.0 and 1.5, more preferably approximately 1.3 is maintained on the bearing surface (16, 20). The measurement (d1−d2) of each bearing surface (16, 20) is equal to =10 mm, preferably between 0.2 and 2.0, preferably no more than approximately 0.6 mm.
Abstract:
A device for continuous measurement of the forces acting upon a movable compressible playable object is provided with at least one transmitter communicating with at least one receiver outside the movable object. The at least one receiver transforms signals received and evaluates them online. The movable compressible playable object, for instance a ball, includes at least one pressure sensor and/or at least one three-dimensional acceleration sensor as well as a converter for transforming signals therefrom to transmit them to the transmitter. A method for the use of this device causes activation of the transmitter in the movable object so that a system is created for the measurement of the forces acting upon such an object wherein the received measuring signals are present in evaluated form, online or offline, to be analyzed. By means of the activation method, the active sensor system is initiated to receive and transmit measuring signals.
Abstract:
The invention relates to an exhaust-gas aftertreatment device, comprising a control unit (4) for controlling a diaphragm pump (2) that draws a urea/water solution out of a circuit and pumps it, via a pressure filter (3), to a metering unit comprising an atomizing nozzle for atomizing the urea/water solution into an exhaust-gas stream.In advantageous developments, the metering unit comprises a metering valve, including an atomizing nozzle, a pressure and temperature sensor, a heating means and a return baffle.
Abstract:
The invention relates to an anchoring system for heart valve prostheses which can be implanted by introduction via the aorta without any major surgical operation. With the heart valve prosthesis according to the invention it shall be achieved that this can be safely and quickly guided through the aorta toward the heart, and can be fixed there. With this, hook-shaped elements are secured to the commissures of the heart valve prosthesis the hooks of which are guided in an outward direction through the heart valve prosthesis material.

Abstract:
A mechanical face seal including a primary ring which is axially movably mounted, and a mating ring (3, 3′, 3″), wherein the primary ring and a mating ring each comprise adjoining sealing surfaces. The primary ring is pressed by a spring against the mating ring. The spring has a bellows-like shape. The spring is made out of an elastomer. The mechanical face seal achieves a small installation space for a mechanical face seal.
