Abstract: A mobile partition wall includes several wall elements (1, 1') that are each suspended from a track (2) secured to the ceiling of a room. Each wall element is provided with coupling valves (30, 32) which pneumatically interconnect the wall elements to allow the continuous throughflow of compressed air. The compressed air actuates pneumatic stroke devices to press respective seal bars (8, 9) against the ceiling and the floor in order to achieve good noise insulation and stability of the wall elements. The terminal wall element (1') includes a laterally extendable sliding termination panel (70) that is connected to a pneumatic drive device for extending the termination panel from the wall element (1'). In this manner, any vertical gap remaining between the terminal wall element and a wall of the room can be simply close and sealed by the termination panel. Pneumatic valves are arranged to control the pressurization sequence of the pneumatic elements.

Abstract: A skylight has a sash, a casement and [spring-loaded.revreaction. carrier arms which are mounted at one end to the casement and at the other end on a pivot bearing on the sash side rail. The sash has spindles cooperating with a U-shaped runner on the side member of the casement. A cover plate borders the channel of the runner and overlaps the spindles when the sash is in the swinging position. When the sash is in the closed position [and the swinging position], the spindles is outside the working range of the cover plate. When the sash is opened and the carrier arm is coupled thereto, it tilts on the pivot bearing. When opened with the sash uncoupled from the carrier arms, the spindle move in the grooves of the runner toward the lower edge of the casement, and the pivot bearing on the casement is lifted off and the sash swings open. The spindles are positioned on the side rail of the sash and move longitudinally when they are seated in individual settings by movement of the handle on the sash cross member.

Abstract: The invention concerns a hinged, swinging skylight in which the sash can rotate and is carried by two arms arranged so they can swivel on the upper end of the casement. The sash is held in the swinging position by spindles that seat in grooves or channels on the side members of the casement and can move therein. In the hinged position, the sash is tightly connected to the arms. To increase comfort and improve operability, the grooves have no limits for the upper ends and the spindles are able to move longitudinally along the side rails of the sash by activating a handle in such a way that they are in the grooves in the swinging position and outside the grooves in the hinged position. At the same time, coupling elements are activated by the handle and are connected tightly to the arms in the hinged position of the sash, and this connection is released in the swinging position.

Abstract: A grain bin lid opener designed to selectively open and close the lid from ground level. A single cable originates from the ground level on one side of the grain bin, proceeds over the grain bin and through the top part of a galvanized pipe and then extends down the other side. The cable is secured at the top part of the galvanized pipe which is welded to the grain bin lid. To close the lid, the cable is looped over a closing lever arm, located near ground level, which is then lowered therefore closing the lid. To secure the lid the lever arm is locked in a bracket. To open the lid the lever arm is released from the bracket and the cable is pulled from the other side of the grain bin. The grain bin lid opener allows the lid to be actuated from the ground level, thus preventing possible injury to a worker who would otherwise have to climb a tall grain bin to open the lid.

Abstract: An apparatus is disclosed for mounting a chamber door between open and closed positions relative to the opening of a sterilizer or autoclave chamber. The apparatus is adapted to be used in either motorized or non-motorized embodiments. The weight of the chamber door is offset by a counterweight and suspended using a cable and pulley system. In the non-motorized embodiment, the door/counterweight system is held in place by a securement, which, when disengaged, permits free motion of the door. In the motorized embodiment, a second cable and pulley system is used to connect the door and counterweight. The cable from this second system is looped around a sheave which is adapted to provide a predetermined frictional force. The sheave is then connected to and rotated by a motor, and upon activation of the motor, the rotating sheave displaces the cable, which respectively raises or lowers the door and counterweight.

Abstract: A power window drive device, including a motor, a worm wheel, a drive drum, and the like, whose manufacturing cost is reduced and which has a reduced size. A rotary shaft, driven by a motor, has a flange extending outward and a spline extending from the flange to the end of the rotary shaft. A drive drum, axially coupled to the rotary shaft, has a shaft hole with a spline and resiliently deformable hook pieces. The hook pieces engage the flange of the rotary shaft, thereby making the rotary shaft immovable in the axial direction. By inserting the end of the rotary shaft into the shaft hole of the drive drum, thereby coupling the splines and making the hook pieces engage the flange of the rotary shaft, the rotary shaft is made immovable with respect to the drive drum in both the axial and the circumferential directions. With this construction, there is no need of separate coupling elements, and the work to assemble the device is simplified.
