Abstract: The mechanism of the invention can be mounted on and in contact with a frame. A spindle (2) is disposed within a shallow strip-like housing (1) parallel to an edge of a glazed sash of a window or door and a slider (3) displaceable on rotation of the spindle (2) is mounted on the spindle in order to drive a latching and/or deployment device for the glazed sash. The spindle can be adjusted by means of a knob-like handle (4) which is drivingly connected with the spindle (2) via gears (5, 6). A safety coupling (15 to 23) which limits the maximum achievable positioning force is arranged inside the handle (4).

Abstract: It is a question of bringing resiliently and successively the arms of a turnstile to their position obstructing a passage to be controlled, and for this a rotary cam 1 in the shape of a star is used interlocked with the rotary assembly of the turnstile and a roller 2 resiliently applied against this cam.To avoid lifting-off between the roller and the cam, a second contact is used between a second roller 2 connected to the first roller or merging therewith and a second cam 10 connected to the first cam or merged therewith, the directions of application of the two roller-cam contacts being opposite.The invention applies to controlling access to urban rail networks.

Abstract: A louvered window shade device for hinged installation relative to the rear door windows of automobiles, particularly of the body types commonly known as fast-backs, hatch-backs, etc., wherein substantial portions of the interior compartments thereof are normally exposed to the direct rays of the sun. A pair of top plates are hinged to the top edge portion of a louvered shade and include oppositely outwardly extending clamps for fixed engagement to opposed top side edge portions of the back door, and a pair of similar clamps engage the respective side edges of the door adjacent the lower edge of the louvered shade. The lower clamps each provide a latch device for openable engagement with the louvered shade.
