Abstract: The present invention relates to a method for producing an engine component having a cooling duct arrangement which has a plurality of cooling ducts, each having an inflow opening, the inflow openings being arranged according to a predefined pattern in an inflow surface of the engine component, and each cooling duct opening into a recess in a wall of the engine component, along which wall a cooling film is to be formed. According to the invention, the pattern is formed in at least one subregion of defined size of the inflow surface, from a plurality of identical isosceles triangles, which are defined by a minimum spacing (k) and by a mean diameter (a) of the inflow openings correlating to the minimum spacing (k). This procedure reduces the complexity of the design process.

Abstract: The present invention relates to a wheel washing apparatus for cleaning a wheel of a motor vehicle, comprising a brush device which includes or forms at least one brush that is placeable against the wheel, a drive device for rotatingly driving the at least one brush, and an advancing device with which the brush device is transferable from a rest position remote from the wheel into at least one use position near the wheel, wherein the brush device is lowerable by means of the advancing device upon moving in the direction of the wheel, wherein the brush device is moveable by means of the advancing device along a trajectory having at least one inflection point upon moving from the rest position into the at least one use position. The invention also relates to a vehicle washing installation and a method for cleaning a wheel.

Abstract: A vehicle washing installation having two stands on which a nozzle beam with a plurality of high-pressure nozzles is held so as be adjustable in height is provided. The nozzle beam is surrounded by a protective body extending along the nozzle beam and having at least one outlet opening for cleaning liquid, the protective body being adjustable in height together with the nozzle beam and being movable relative to the nozzle beam upon striking an obstacle, the movement of the protective body relative to the nozzle beam being detectable by a sensor assembly in order to provide a control signal.

Abstract: A wheel washing apparatus is provided, including at least two washing brushes, each of which is capable of being driven in rotation about a brush axis, wherein the brush axes of the at least two washing brushes are different from one another. In order to provide a wheel washing apparatus which allows a better cleaning result to be achieved, it is proposed that the at least two washing brushes be capable of being driven in rotation about a common central axis which is different from the brush axes.

Abstract: The present invention pertains to systems, methods and devices for online reservation inquiries of individual shares of an item. The system has a server that makes available a 3D graphic model of the item as well as reservation statuses of the shares of the item for inquiries, and a client computer for displaying the 3D graphic model on a user screen from an arbitrarily changeable perspective. The 3D graphic model of the item contains a graphic object for each share that is spatially related to this share in the 3D graphic model. The server transmits the 3D graphic model of the item and the reservation statuses of the shares of the item to the client computer in response to respective inquiries. The manner in which each graphic object is displayed in the arbitrarily changeable perspective of the 3D graphic model is defined by the reservation status of the share to which it is related.

Abstract: In order to further develop a vehicle washing installation comprising at least one nozzle arrangement which is movable past a vehicle to be cleaned in the longitudinal and transverse directions thereof and is adapted to be supplied with a cleaning liquid for cleaning the vehicle, so that it is of structurally simpler design and is less susceptible to failure, it is proposed, in accordance with the invention, that the nozzle arrangement comprise at least two groups of nozzles, with a first group of nozzles facing the vehicle to be cleaned during a transverse movement of the nozzle arrangement and a second group of nozzles facing the vehicle to be cleaned during a longitudinal movement of the nozzle arrangement.
