The invention relates to a connection of a crankcase (3) of an internal combustion engine (1) to a cylinder housing (2) of which at least one housing part is made of light metal. The housing parts (2, 3) lie with their respective housing flanges (4, 5) in surface contact one against the other and are clamped seal-tight to each other with the aid of retaining screws (7). The retaining screws (7) are of light metal and a curing liquid seal (18) is between the housing flanges (4, 5) so as to lie against both sides. In this way, a connection for a light metal cylinder housing (2) with a crankcase (3) is achieved by using light metal housing materials. A reliable seal is provided which is permanently resistant to the operating loads of the engine (1).

A casting roller or belt for a revolving chill mould of a strip casting system for the manufacture of an aluminium alloy strip and a strip casting system for manufacturing an aluminium alloy strip comprising at least one revolving chill mould with a casting gap. A method for manufacturing an aluminium alloy strip by means of a strip casting system. The object of providing a casting roller or belt or a strip casting system, by means of which, adhesion to the casting roller or belt is avoided during strip casting and a low-segregation and crack-free aluminium alloy strip can be produced, in particular under industrial conditions, is achieved by a specific surface structure, in that the surface of the casting roller or belt has a roughness value Sa of more than 5 μm and an average peak count RPc(0.5 μm) of less than 42 cm−1.

The invention relates to a method for controlling the disposition of graphical elements, whose positioning is effected by a layout manager component, according to which the elements are listed in tuples according to a predetermined method. A Boolean condition is evaluated for every tuple and if said Boolean condition is met an associated command is carried out that comprises the control command for the layout manager component. The inventive method is preferably used in generator systems for generating applications that extract data bases, whereby for every line of the result table graphical objects are generated and said objects are disposed on the graphical surface by way of the indicated method.

A process for manufacturing a road-bound, horizontally fitted vehicle body with a roof unit having an outer skin and an inward facing ceiling, or an outer skin and an inward facing ceiling with a ceiling frame, whereby the roof unit is a unit ready for installation, and a basic structure having longitudinal frames and side wall columns, the ceiling and the outer skin along with the basic structure having joining configurations that mate with each other at mutual places for joining. The ceiling has at least one fitting from a group of fittings consisting of fittings for a ceiling cover, interior cladding, cushioning against impact, sun shields, an interior rear view mirror, interior lighting, wiring, operating and display elements, sliding, raising, folding, lamellar and glass roofs, and their frame parts and the drive elements, and roof hand grips. The process includes the steps of either inserting the roof unit with the fittings from the front or rear, lowering the roof unit with the fittings or raising the roof unit with the fittings so that mutual configurations for connecting purposes of the roof unit and the basic structure are brought together and joined permanently with each other. The side wall columns of the basic structure have a configuration for connecting purposes and a configuration for connecting to the side wall columns is provided on the ceiling or ceiling frame.

A method for uphill/low pressure casting of a liquid melt in a device which has a casting furnace lying below a casting table, a mould with an underlying pouring-in opening and a slide valve closure forming a flow-through channel having a substantially straight longitudinal course during casting the liquid melt. The casting method constitutes casting the liquid melt in the pouring-in opening of the mould, shutting off the slide valve closure by displacing an overlying opening section and an underlying opening section of the flow-through channel directly after casting the liquid melt in the mould, which liquid melt is still in the pouring-in opening. The liquid melt is lowered below the mouth opening of the riser pipe and the mould is placed on the riser pipe so that a downward pressure is set between the slide valve closure and the mouth opening of the riser pipe which behaves elastically flexibly.
