Abstract: An improved system for making notch on notch joints and the like wherein the members to be joined have notches formed across a portion of their width. Each member includes a longitudinal extension beyond the notch and these extensions cooperate to form a joint which has a flush exterior and yet is substantially as strong as a conventional notched joint. One configuration allows the same joint members to be employed to form inline, right-angled and T-shaped joints.

Abstract: A cuff type air seal for sealing the overlap of partly telescoped parts that has an annular body of rubber or elastomer material having annular internal air sealing beads thereon which are adapted to fit on outer peripheral surfaces of the parts adjacent their overlap. Both parts have fixed outer diameters but the outer part may be a blow molded annular component having an internal diameter which varies so usually there is clearance and a potential air leak path at the overlap. An adjustable clamp encompasses the air seal and provides a constricting force so that the air sealing beads seal on the outer surfaces of the parts even though the clearance remains. The cuff is formed with a pocket that receives and retains a headed portion of the blow molded part when telescoped over the facing headed portion of the first part, particularly when the clamp is constricted.

The facing surfaces can be flat and planar. The plurality of facing flat surfaces initially face each other in an interlocking arrangement which is not tight. A single threaded adapter is then tightened to draw the plurality of facing surfaces of one member tightly against the corresponding facing surfaces of the other member.

Abstract: A double-containment pipe fitting and system for joining sections of double-containment pipe includes an outer containment housing, an inner carrier housing, and a plurality of restraining devices. The containment housing has a plurality of open ends. Each open end is constructed to securely connect to an open end of a containment pipe. the carrier housing has a plulrality of open ends constructed and arranged for positioning within the containment housing. Each open end of the carrier housing is constructed to securely connect to an open end of a carrier pipe. One restraining device is provided for each open end of the containment housing.

The carrier pipe and containment pipe are otherwise unrestrained against expansion and contraction.

Abstract: A portable fence system including a snow fence panel having a wood frame of 2".times.6" posts bolted together at the corners, with a 4-foot wide strip of plastic snow fence material pulled taut across the center. Each panel is 8 feet long, with a height of 6'-8" or 8'-0", depending upon the application. In both cases the geometry of the frame is optimized for maximum snow trapping efficiency and maximum snow storage, and an opening at the bottom is optimized to eliminate the tendency for snow deposition at the fence. Panels are connected to one another by rebar pins passing through specially designed rotatably mounted U-clips, which also provide attachment to rebar anchors driven into the ground. The U-clip-and-pin connections allow rapid installation and take-down, and add flexibility needed for proper installation in irregular terrain. Panels can be overlapped at either the top or bottom as required to limit space between panels to 11/2", which improves trapping efficiency.

Abstract: A constant velocity joint has a low profile boot retainer which seals and retains a boot on the joint. The boot retainer also retains the joint's internal components within the outer race. The low profile feature allows for the use of this boot retainer when space is at a premium. The retainer has an inner and outer band which sandwich the rubber or plastic boot between them and provide a seal between the boot and the constant velocity joint outer race.

Abstract: A device for attaching a water jet device to a concentrate container or a reservoir by means of a clamping device or a foot, comprising a connecting piece, in which the foot is arranged to be fixed and put into sealing abutment with the insert piece in one movement, for which purpose the connecting piece is provided externally with threaded parts designed to cooperate through a bayonet catch with a complementarily designed part of the foot. The container, which is designed as a flexible bag, may be provided with a base plate at the position of the connecting piece, said connecting piece being designed as an insert piece, so as to ensure that the outlet opening of the insert piece remains open.

Abstract: A sleeve for clamping and connecting items to be clamped or connected includes a plurality of windings of heat shrinkable material bound into a sleeve which is placed over the item to be clamped or items to be connected. The heat shrinkable material in the sleeve is secured in such a way that upon application of heat to the sleeve, the heat shrinkable windings will shrink and exert inward compressive pressure about the inner surface of the sleeve and thereby about the item to be clamped or the items to be connected. When desired for clamping a tubular item, the clamp can be incorporated as part of the tubualr item by incorporating the windings of heat shrinkable material into the end of the tubular item. The method of clamping of the invention includes the steps of positioning a tubular item over the item to which it is to be clamped and then placing a pluraltiy of windings of a heat shrinkable material about the tubular item where it surrounds the item to which it is to be clamped.
