Abstract: Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.

Abstract: A frame which has a wire extending across a rear of the frame is hung on a wall by an integral flexible spring member shaped to define a center mounting plate fastened to lie flat on the wall and a spring strap standing at right angles to the plate with a pair of arms each extending outwardly from the mounting plate along the wall to a respective side of the mounting plate. The arms receive and locate the wire extending along the arms and depending from ends of the arms to the sides of the frame. The arms can flex and the arms allow longitudinal movement of the wire along the arms to allow movement of the frame side to side relative to the mounting plate. A stiffening rod can be inserted onto the strap.

Abstract: A method of preparing a reinforcing structure for use in manufacture a pultruded part where the reinforcing structure is pulled through a pultrusion die in a continuous longitudinal pull direction. The method includes arranging a plurality of first reinforcing fibers in a transverse direction and attaching a permeable transport web of staple fibers to the first reinforcing fibers such that the portion of the first reinforcing fibers oriented in the direction transverse comprises at least 30% of a volume of materials comprising the reinforcing structure.

Abstract: A method for forming a pultruded part includes collating reinforcing fibers by providing a first layer of reinforcing rovings extending in the longitudinal pultrusion direction, applying onto the first layer an intermediate layer of reinforcing fibers at least some of which include at least portions thereof which extend in the transverse direction and covering the intermediate layer with a second layer of rovings extending in the longitudinal direction. Alternatively the transverse fiber layer is formed on the inside surface of a hollow part. To the collated fibers is applied a urethane resin so as to permeate through the layers and the materials are passed through a die to form a thermo-set cross-linked poly-urethane. The transverse layer or layers are relatively thin having a weight less than or equal to 0.5 ounces per square foot and more preferably as low as 0.25 ounces or 0.1 ounces.
