Abstract:
A housing for an automatic door operator comprising a header section, a closing section and a terminal section. The header section includes two legs and a connecting leg which connects the two legs to one another. One of the two legs includes an end portion having a ball projection and an undercut. The closing section includes a ball projection and an indentation at one end and the terminal section at the other end. The closing section is removably attached to the header section through the engagement of the ball projection of the closing section with the undercut and the engagement of the ball projection of the one of the two legs and the indentation. The housing serves to house mechanical and electrotechnical components for the automatic door operator.
Abstract:
A moveable track cover is provided for use with a mechanism configured to move along a track. One example of such a mechanism is a pipe racking system used on off-shore oil and gas platforms. One end of the moveable track cover is connected to the pipe racking system mechanism which moves along the track. The other end of the track cover is spooled onto a drum. Rotation of the drum is controlled by a motor which exerts enough force to maintain the track cover in constant tension. When the pipe racking system mechanism moves towards the drum, the motor rotates the drum to roll the track cover onto the drum. When the pipe racking system mechanism moves away from the drum, it pulls the track cover off of the drum. By attaching a track cover to each side of the pipe racking system mechanism, the track along which the pipe racking system mechanism travels is kept covered at all times. The track cover may be constructed of a sheet of stainless steel strengthened by rib assemblies. The rib assemblies may include wear strips to facilitate easy sliding of the track cover, and the top of the sheet will preferably have a non-skid material adhered to it to prevent workers from slipping on the sheet when they are walking across it.

Abstract:
A cable control device (10, 110) in a sectional overhead door (11) having a motor-driven counterbalance system (30) including a spring-loaded drive shaft (31), cable drums (35) carried by the drive shaft, cables (C) attached to and interconnecting the cable drums and the door and forming and releasing cable wraps of the cable on the cable drums upon raising and lowering of the door, and shrouds (10, 110) associated with the cable drums engaging the cable wraps through substantially the circumference of the cable drums to maintain axial alignment of the cable wraps with the cable drums in the event of the development of slack in the cables.
Abstract:
A mechanism for assembling sliding glass doors, comprising an upper track (3), a lower parallel guide (5) between which are arranged fixed sheets (1) and moveable sheets (2). The track (3) has an inverted L-shaped cross section and its vertical member is provided with means (16) for fastening stops, the lower part of said member ending in an inverted groove (14) with an upper rib (15) on which slides the wheel (30) of the suspension heads which comprise two plates (20 and 21) that can be opposed and fixed together, with the interposition of a pivot (27) to regulate the separation between said plates. The horizontal member (8) of the L-shape is provided at the end with a channel (18) for fixing a shape (19) to restricts the lifting of the sheet (2).
Abstract:
A doorway system, comprising a novel mechanism for controlling tall glass doors and making their installation and repair much easier, and a header that can be used with standard size or tall glass doors, is disclosed. The mechanism features circular bearings, a specially-designed bottom spindle and an upper, adjustable, pivotable housing. The header houses, among other parts, the adjustable housing and allows pre-cut, modular parts to be assembled at the building site.
