Abstract: A method for production and/or storage of a consumable liquid is provided. The method includes (i) providing a liquid container, which is open on one side and has a container wall with an inner wall surface, where the inner wall surface is formed at least partially as a surface of a solid natural stone; (ii) cooling down at least a partial section of the liquid container with respect to the temperature of the surrounding atmosphere; (iii) introducing a liquid into the liquid container that has been cooled down according to step (ii); and (iv) initiating a chemical and/or biochemical conversion of the liquid that has been filled in, such as fermentation or a conversion of sugar to alcohol, for generating the liquid or a pre-product, wherein during the conversion no further measure or process for cooling the liquid container and/or the liquid residing therein is, respectively, taken or performed.

Abstract: A liquid container for producing and/or storing liquids, in particular alcohol-containing liquids, intended for consumption comprises a container that is open at one end, can be closed by a lid and container walls with an inner wall surface that is at least partially, in particular substantially entirely, in the form of a surface of a solid natural stone. Also described are various methods for producing such liquid containers and a method for producing and/or storing drinkable liquids using such containers.

Abstract: A method for machining a wall of a cylinder of an internal combustion engine, in which recesses in the wall are introduced by mechanical machining. The invention is characterized in that the wall is radiated with a medium under high pressure after the mechanical machining in order to introduce micro-recesses.

Abstract: The invention provides a method for detecting the improper interchanged installation of left and right lambda probes in an internal-combustion engine having two cylinder banks, each of which has an exhaust gas catalyst with a lambda probe and a lambda control unit assigned thereto, and whose injection valves can be switched off at least by cylinder bank. The injection valves of one of the two cylinder banks are switched off at least for a time which corresponds to the reaction time or change-over time of the lambda probes. The signal from the lambda probe assigned to the switched-off cylinder bank is then compared with a predetermined threshold value at the end of the switch-off time of the injection valves. An incorrect connection of the lambda probes is detected when the lambda probe signal exceeds or falls below the threshold value.

Abstract: Process for welding a weld-in part in a weld point comprising a metal plate and a metal covering lying thereon with two tools of which one is formed by a welding head and the other by a drill for preparing the weld point by a drilling process. The drill attached to a revolving device initially in one operating position, by means of a lifting motor which can be moved in a controlled manner between a return position and a machining end-position and vice versa, performs the process at least until the metal plate is drilled (machining end-position) in preparation of the weld point. By pivoting of the revolving device, a welding head arranged on the revolving device and equipped with the weld-in part is then brought into an operating position above the prepared weld point to perform welding, meanwhile the drill is coupled to the lifting motor when the welding head is coupled to the lifting motor when the drill is uncoupled to perform welding on completion of the drilling process.

Abstract: In a crank loop frame for a crank loop drive of an internal combustion engine for the transformation of a back and forth motion into a rotary motion, each of the slideway frame, webs of the crank loop frame includes portions of a heat capacity sufficient for a homogeneous distribution of the heat disposed both above and below the slideway of the slideway frame web. Each of the slideway frame webs has an H-shaped cross-section and contains a longitudinal slideway web portion as well as two leg web portions disposed tangentially at the longitudinal edges of the slideway web portion. The areal center of gravity of each slideway frame web is disposed to the side of its respective slideway remote from the slide, thereby to promote dissipation or the homogeneous distribution of heat to both sides of the slideways.

Abstract: A device which removes dust and/or other impurities from photographic films, records or other data carriers has one or more brushes whose bristles sweep along the surface or surfaces of a data carrier while the data carrier moves relative to the bristles and/or vice versa. The electrostatic charge which develops as a result of frictional engagement between the data carrier and the bristles is led away by providing each brush with bristles at least some of which consist of conductive material and are grounded via electrodes which contact the tips of the bristles and/or by way of the core of each brush.
