Abstract:
A window regulator for operating a slidable window panel. The window regulator includes a drive drum (14) mounted for rotation in a wire winding direction to wind a first wire (W1) having one end mounted on a window panel carrier (C) and in a wire unwinding direction to unwind the first wire. A driven drum (15) is mounted for rotation in a wire winding direction to wind a second wire (W2) having one end mounted to the carrier and in a wire unwinding direction to unwind the second wire. The drive and driven drums (14, 15) come into connection with each other for rotation of the driven drum in unison with the drive drum only when the drive drum rotates in its wire unwinding direction. A device (31, 32, 17) is provided for making a connection between the drive and driven drums for rotation of the driven drum in unison with the drive drum in response to rotation of the drive drum in its wire winding direction.
Abstract:
A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier. The mounting bracket may include a first mounting surface disposed at a non-perpendicular angle relative to an exterior surface of carrier when the window balance assembly is in an uninstalled configuration. The first mounting surface may be substantially parallel to the exterior surface of the carrier when the window balance assembly is in an installed configuration and the mounting bracket is disengaged from the carrier.

Abstract:
A safety cabinet has a body, a pair of doors each pivotal on the body about a respective axis between an open position and a closed position, respective spaced outer guides on the body juxtaposed with the doors, and respective elements displaceable along the guides and coupled to the doors for movement between outer positions when the respective doors are in the open position and inner positions when the respective doors are in the closed positions. A catch between the guides is engageable with the elements and shiftable therewith. A spring also between the guides is engaged between the catch and the body and biases the catch inward toward engagement with the elements. A release device secured between the catch and the body normally holds the catch in an outer position with the spring in a tensioned condition but can release the catch and thereby push the elements with the catch into their inner position to close the doors.

Abstract:
A safety mechanism for a closing installation, comprising a shaft and an element having teeth for cooperating with a catch which oscillates during rotational movements of the shaft. The mechanism further comprises a safety system including a ring for braking the oscillatory movement of the catch. The movement of the ring is controlled by a detecting system that detects the state of a spring which used to compensate the torque exerted on the shaft by the screen body.
Abstract:
An automatic sliding door closure device for use with a sliding door on a track. The device comprises a housing attached to the door having a connecting arm attached to the housing. A pulley rotatably mounted within the housing guides a cable having an exterior end attached to the doorframe and an interior end connected to the gear, rotating the gear when the sliding door is slid along the track. A spring engaged with the gear tensions rotation of the gear as the door is moved. An airtight cylinder parallel with the track has a plunger arm connected to the connecting arm that is drawn within the cylinder as the door is moved. A flexible member connected to the plunger arm creates an air cushion within the cylinder. An airflow control valve controls intake and outlet of air into the airtight cylinder controlling the closure speed of the door.
