Abstract: A dock leveler having a deck-assembly, a first hydraulic cylinder to power said deck assembly to a raised position, lip mounted to said deck assembly, and a second hydraulic cylinder for powering said lip into an extended position. An hydraulic power circuit is coupled to the first and second hydraulic cylinders to control movement of said deck and lip. The hydraulic power circuit includes a pump to deliver fluid under pressure, a first valve operatively coupled to the pump to control fluid flow to the first hydraulic cylinder. A second valve is operatively coupled to the second hydraulic cylinder. An adjustable relief valve is coupled to the second valve to prevent a reduction of fluid pressure to the second hydraulic cylinder after the pump has supplied fluid under pressure through the second valve to extend the lip.

Abstract: This invention is for a process for producing a water-in-oil emulsion and edible margarine-like spread composition having a fat content of less than 80 percent by weight and having the approximate consistency of margarine, the process comprising forming a liquid dispersion of a water phase and a liquid fat phase of a substantially hard fat and a liquid soft fat, followed by cooling of the dispersion and subjecting the cooled dispersion to a shearing force sufficient to produce a water-in-oil emulsion, and discharging the emulsion to provide a product having the approximate consistency of margarine at room temperature.

Abstract: A reinforced concrete floor structure having reinforced concrete beams and girders supporting a metal subfloor and a monolithic concrete layer. The metal subfloor comprises alternating first and second flooring units wherein the first flooring units span across a plurality of the beams and thereby enhance the load carrying capacity of the floor structure. In one embodiment, the first flooring units comprise cellular flooring units that provide for the distribution of wiring throughout the floor structure. In alternative embodiments, the first and second flooring units each comprise cellular flooring units or each comprise non-cellular flooring units. The metal subfloor presents openings in the region of the beams and girders so that the monolithic concrete may comprise the concrete of the beams and girders and the layer of concrete covering the metal subfloor.

Abstract: A standing-seam roof system with elevated sub-purlins supported on concealed slip assemblies is provided. A uniform thermal-insulating value of the roof system is maintained by elevating the roof panels substantially above the undeformed depth of the thermal-insulating blanket. Each clip assembly consists of two parts allowing level adjustment after the fastening of the clip assembly.

Abstract: A door assembly and method for making a door assembly that has a front steel skin with a predetermined embossed pattern, a back steel skin that has a substantially textured flush surface and a polystyrene core one side of which has an embossed design substantially identical to the embossed design of the front steel skin and a back surface that is substantially flush. The front and back steel skins have a pressure sensitive hot melt adhesive applied thereto and the center polystyrene core is attached between the front and back steel skins and passed through a series of pinch rollers to apply predetermined pressure to the front and back skins to secure the front and back skins to the polystyrene core. The front and back skins are preheated to a predetermined temperature sufficient to maintain the pressure sensitive hot melt glue in a soft and tacky state.
