Abstract: Tiles (7) having significant depth are placed on a gameboard (1) having projections (2) on its upper surface. The protrusions (2) engage recesses (8) formed on the corners of the tiles (7) in order to locate the tiles (7) in position on the game board (1). The recesses (8) may extend for only part of the depth of the tiles (7) so that they are not visible from the top of the tiles (7), thereby affording visual continuity between the (tiles7). The protrusions (2) may engage the recesses (8) as a friction fit, to hold the tiles (7) firmly in place. Alternatively, they may engage the recesses (8) as a loose fit, thereby to afford location of the tiles (7) whilst allowing their easy removal from the game board (1).

Abstract: The invention relates to a steam circuit process device, comprising a reservoir for a liquid working medium; an evaporator in which the working medium is evaporated by heat supply, the vaporous working medium being fed to an expander for expansion and for carrying out mechanical work and being subsequently liquefied in a capacitor which communicates with the reservoir; a working medium pump for supplying working medium from the reservoir to the evaporator. The invention is characterized in that liquid working medium is supplied in the direction of flow of the working medium upstream or in the region of the capacitor to the working medium exiting the expander.

Abstract: A diaphragm pump (1) has at least two pump heads (3) arranged around a central eccentric pump drive (2), the diaphragms (4) being drivingly connected to the eccentric pump drive (2) via connecting rods (5). The eccentric pump drive (2) has a connecting rod ring (6) to which the ends (9) of the connecting rods are connected via elastic intermediates (10).

Abstract: A coupling assembly for providing a fluid connection comprising a female connector, a tube, a retainer and a cap. The female connector defines a bore. The bore extends axially inwardly into the connector from an entrance. An annular face is defined in the bore axially inwardly of the entrance. The tube is received within the bore. The tube has an enlarged upset. The retainer is disposed in the bore. The retainer has a member directly contacting the upset and extends to the annular face to retain the tube in the bore. The cap is slidably mounted on the tube and is attached to the female connector. The cap has a protrusion directly contacting the upset.
