Abstract: A connector assembly (1,45;2) comprising a plug-in connector (1,45) and a socket connector (2). The plug-in connector (1,45) is provided with a lever-type locking element (5;15;25;40) having two free ends. At one free end an outwardly projecting pawl-type latching element (8;18;28;41) is disposed, while the other free end is designed as a gripping end (5';15';25';40'). The socket connector (2) is provided with a slot-type opening or recess (9), so that when the plug-in connector (1,45) is pushed into and mates with the socket connector (2), the latching element (8;18;28;41) engages the slot-type opening or recess (9), from the inside (2') of the socket connector (2), thereby latching the connectors (1,45;2).

Abstract: A multiplayer surprise action game in the form of a central unit which defines a spiral pathway around its upper portion and a housing for an object-projecting mechanism in its lower portion. The housing has a plurality of openable doorways spaced around it. Each doorway defines a player station. The mechanism is randomly rotated to aim at only one of the doorways at any time, while concealing from the players the doorway at which it is aimed. The players move play pieces along the pathway and manipulate an advancing mechanisn that unpredictably sets off a noise maker after an apparently random time. The players have a chance to prepare, and then they activate the projecting mechanism. The mechanism projects the object (such as a toy snake) outwardly through the doorway at which it is then aimed, to the surprise of and excitement of the players. The particular player station/doorway from which the snake emerges may be used by the players to adjust the further play of the game.

Abstract: The method described coats the interior of a tube-like support with the binding partner of the analyte. Analyte and anti-analyte-label conjugate are added. When the tube-like support is rotated end-over-end, the thin layer of analyte and conjugate readily react with the binding partners to form an immobilized label complex. When rotation stops, the reaction quenches to provide precise timing. The label complex is released and measured.
