Abstract: A drip stop spacer spaces a roof or wall covering such as sheet plastic from purlins or other frame members of a greenhouse. An elongate elastic cylindrical helix is formed of a length of helical chord of flexible material with chord depth dimension in the radial direction of the helix selected to achieve a desired spacing between a covering and frame members. The helix diameter is sufficient to place the helix in turns around the frame members with lead or pitch between turns of the helix selected to prevent sagging contact of the covering against frame members. The spacer elements can be installed by twisting or winding around the purlins without requiring removal of frame members. Condensation flowing down the covering bypasses the purlins and purlin dripping is avoided.

The bar hanger permits rapid installation of the conduit hangers and spreads the load over both chords.

Abstract: A suspended ceiling system for a clean room employing short cross runners connected to longer main runners. The connections serve to coax the cross runners against the main runners to keep the system intact and air tight. The grid of cross and main runners creates rectangular areas between them into which ledges extend from both runners. For a dry seal, a sealing gasket adheres to the ledges' upper surface. Ceiling components such as lights, filters, and tiles sit upon the gasket to provide the seal. For a wet seal, a trough sits upon the ledge and circumscribes each rectangular area. The trough contains a liquid material into which a knife edge depending from the ceiling fixtures sits. A continuous threaded slot runs along the center of the members' bottoms. This allows the attachment of accessories such as removable walls. The runners have a generally U-shaped cross section that gives it sufficient strength to bear the live weight of a person.

Abstract: A master power track is mounted along the periphery of a suspended ceiling. Plug-in-connected with this master track are light-weight modular power tracks serving as grid members of the suspended ceiling. The master track, which also serves as the conventional L-bar for the suspended ceiling, is provided with a relatively high frequency voltage; which voltage is then available at any point along the individual modular power tracks. The modular power tracks also serve as the T-bars of the suspended ceiling. Ceiling panels and light-weight fluorescent lighting fixtures are placed in the suspended ceiling grid structure, with each lighting fixture being plug-in-connected with one of its adjacent modular power tracks. The plug-in connection is accomplished below rather than above the ceiling; which implies that the space above the suspended ceiling may safely be used as air plenum. However, by using grooved ceiling panels and special connect means, the resulting ceiling is completely conventional in appearance.

Abstract: In order to provide a pleasing aesthetic appearance, and also in order to enable concealed, directional lighting to be used, an openword grid-like suspended ceiling system has outer squares which contain four inner blades forming an inner square surrounded by four rectangles. Light fittings are associated with the rectangles so that the axis of a light fitting can be inclined. In order to enable the ceiling system to be packaged at low packing density, the four inner blades are hinged to each other and collapse so as to lie parallel to each other. After opening out, they can be hooked into the sides of the outer squares.

Abstract: Angular sections form frames which can be fitted together in the frame plane in modular fashion. Legs of the sections are formed so that through two interconnected legs of adjacent frames notches of T-shaped cross-section result, into which hammer head-shaped ends of pull rods can be introduced. By means of the pull rods, ledges can be pressed against filter and/or light fixture housings, which in this manner are pressed against legs of the profiles on the opposite housing side, adjacent frames thus make it possible in a correspondingly compact model to attach filters and light fixtures without the distance between two adjacent filters or between a filter and a light fixture occupying a width that would impair the flow profile of the air issuing from the filters.

Abstract: An improved connector for a supporting filter bank framework is disclosed which comprises a body member defining at least two extensions radiating from a common central location.

Adjacent connectors are adapted to be joined by an interconnecting channel of predetermined length, with the ends of the channel being positioned within aligned extensions of adjacent connectors, and with the ends of the channels abutting the respective protuberances. A supporting latticework is thereby constructed which defines a plurality of rectangular open areas, and the length and width dimensions of each open area is automatically established.

Abstract: A fire rated, demountable partition structure is disclosed which provides H-shaped studs having a core of combustion-resistant insulation material and opposed channel-shaped metal members secured to opposite faces thereof. Spline clips secure one side of the stud to the panel at joints therebetween. Each clip includes a lateral projection extending with a close fit into a kerf in the edge of the panel and a reverse bend providing opposed clip walls which fit along opposite sides of an adjacent flange on the stud. If the partition is exposed to a fire or the like, which tends to cause shrinkage of the panels and opening of the joints, the core of the stud bridges the joint and prevents direct exposure of the metal channel elements of the stud to heat or water through the opened joint. The spline clips are free to expand if the clips are subjected to greater heat than the channel members so that the stud is not caused to bow toward the fire side of the partition.
