A method and apparatus for reinforcing duct work is provided. In one embodiment, a reinforcement comprises a conduit having a first end and a second end. A pair of plugs is insertable into the first and second ends of the conduit. Each of the plugs has a groove extending along the circumference of the plug, and the plugs are crimped inside the conduit along the grooves. Each of the plugs may have a threaded end extending out of the plug and being retractable into said plug. Alternatively, each of the plugs may have an internally threaded opening extending at least partially through the plug. In this embodiment, the conduit can be secured to duct work by aligning the conduit with holes in the duct work, and inserting a bolt through the holes and into the internally threaded openings of the plugs.

Plugs for use in conduits to reinforce air conditioning ducts, and methods of manufacture and use

A method for making air turning vanes each having formed therein a pair of locking protuberances which adapt the vanes to self-gripping attachment between a pair of rails to fabricate an air turning vane and rail assembly utilizes an elongated length of double plate airfoil vane stock including a front plate having an outer concave surface arcuately bowed about the central longitudinal axis of the plate, and a rear plate having an outer concave surface arcuately bowed about the central longitudinal axis of the rear plate. A vane of a desired length is severed from the vane stock, and the outer concave surface of the rear vane plate is impacted by a punch with sufficient force to deform from the inner surface of the plate a generally hemispherically-shaped button having a lower severed wall which forms a locking lip. The apparatus according to the present invention includes a guillotine-like shearing structure/vane stock support fixture which vertically slidably supports shear blade. The fixture has through front and rear walls thereof longitudinally aligned, crescent-shaped apertures for longitudinally slidably receiving vane stock. A pair of longitudinally aligned, downwardly pointing punches attached to the front and rear surfaces of the shear blade, rearward or upward from a wedge-shaped piercing point of the shear blade, are effective in forming a locking protuberance forward of the rear transverse edge of a severed vane, and a locking protuberance in the vane stock, rearward of the front transverse edge of the vane stock, when the shear blade is forced sharply downward to sever a vane from a length of vane stock.

An apparatus for assembling air turning vane and rail structures of the type having a plurality of turning vanes consisting of longitudinally spaced apart curved airfoil plates disposed between a pair of parallel upper and lower plate-like rails, and used to promote laminar air flow in heating, ventilating and air conditioning ducts, compresses an array of vanes between a pair of rails to interlock upper and lower transverse edges of the vanes with the upper and lower rails. The apparatus includes a work table for holding the lower rail of a vane and rail structure to be assembled, and lower and upper laterally disposed comb-like vane guides disposed above the work table provided with laterally spaced apart, vertically aligned pairs of slots, each adapted to receive a vane in an upstanding position above an intended fastening location in the lower rail. A ram plate driven downwardly by a linear actuator presses downwardly on an upper rail placed in position above the upper transverse ends of the vanes, causing the upper transverse ends of the vanes to lockingly engage with the upper rail, and to couple downward translational motion of the ram plate and upper rail into downward motion of the lower transverse edge walls of the vanes, causing the latter to lockingly engage the lower rail.

Apparatus for assembling air turning vane and rail structures

An air turning vane and rail assembly for promoting laminar air flow in angled duct work transition sections includes longitudinally spaced apart air turning vanes transversely disposed between a pair of flat rails. Each turning vane is a hollow double-plate airfoil having a convex front airfoil plate, and a concave rear airfoil plate joined at their edges. Each rail has a plurality of longitudinally spaced apart, upstanding tabs each having an upper trapezoidally-shaped portion and a lower rectangularly-shaped pedestal portion. Each tab has a pair of laterally opposed, outwardly and downwardly angled edge walls, each joined at its lower end to a vertically disposed pedestal edge wall. The width of the pedestal is greater than the maximum lateral spacing between the front and rear airfoil plates. Thus, when a rail tab is inserted into an entrance opening between front and rear vane plates, wedging action of the angled tab side walls on the inner surfaces of the plates deforms the end portions of the plates to a flatter, less curved contour, causing the vane to firmly grip the tab. A protuberance protruding forward from the rear airfoil plate towards the front airfoil plate snaps into an aperture provided through the tab near its base, when a vane is pushed down on a tab sufficiently far, causing locking engagement in addition to a gripping engagement between vane and rail.

An information locket includes an outer housing having substantially parallel front back walls and a partial side wall, and an inner member which is pivotally connected between the front and back walls. The inner member includes a magnifying lens portion and an inner member side wall. The inner member has a storage position in which it is held between the front and back walls of outer housing with a portion of the inner member side wall forming the remaining portion of the outer housing side wall. An information bearing card, which contains personal and medical information printed in substantially reduced form, is held in a compartment formed by one surface of the magnifying lens and the inner member side wall. When the inner member is pivoted to a viewing position, the information bearing card may be removed from the compartment and read by looking through the magnifying lens portion of the inner member.
