Abstract: A strategy game or game of patience having a playing surface (1) of higher complexity and with increased playing incentive. According to the invention to attain that object it is proposed that the playing surface (1) has a plurality of mutually overlapping circular surfaces (2, 3, 4, 5, 6) each of the same respective radius R, and with playing elements (7, 8, 21, 22) which are respectively arranged on at least one of the circular surfaces (2, 3, 4, 5, 6), wherein all playing elements (7, 8, 21, 22) which are disposed on any circular surface (2, 3, 4, 5, 6) belonging completely to the playing surface are rotatable jointly about the respective circle center point.

Abstract: A cooling arrangement with a housing for receiving electronic printed circuit boards or plug-in modules, and with an air-conditioning device which is connected via a coolant-conducting feed line and a return-flow line with at least one electronic component, which is to be cooled, on the respective printed circuit board or plug-in module. The feed line is coupled with at least one component feed line assigned to the electronic component. The return-flow line is coupled with at least one component return-flow line assigned to the electronic component. The component feed line and the component return-flow line have coupling elements attached at ends of the respective printed circuit board or plug-in module which, together with the counter coupling elements of the feed line and the return-flow line attached at the end of the housing, form a coupling connection, which is releasable.

Abstract: The invention relates to game which is provided in the form of a ball track and which is comprised of individual components having roller rails. The roller rails have a guide for balls that roll and have at least one through boring for leading into a connecting element arranged below said through boring. The connecting element has a ball passageway which is essentially vertical and/or which is distinctly slanted with regard to the horizontal. In order to provide a ball track which can be variably composed of few different elements (roller rails and connecting elements), whereby a high degree of stability should be attained also in high structures, roller rails and connecting elements can be assembled side by side or one above the other to produce a ball path which leads away over more than one component, whereby the ball path horizontally extends at least on a section of the rolling rail.
