Abstract: Efficient paving operation requires that the levelling operation of asphalt be carried out accurately along a reference line which follows a given direction along a roadside. A simple and effective automatic control device for controlling the steering direction in conjunction with adjustments of the screed for an asphalt finisher (shortened to finisher) is presented. The control device automatically regulates the extension or retraction of the screeds on both sides of the finisher in reference to a visual display of the reference line following some objects along the roadside. The visual detection system of control is simple and economical and provides an accurate control over the direction of paving.

Abstract: A composite cover material to be used for making an integrally foamed article comprises a permeable fabric (10) and a thin layer of latex foam (15) strongly bonded via bonding zone (17) to said fabric. The latex foam layer (15) is made by applying high molecular latex material such as rubbers or synthetic resins as coating to back surface (12) of said fabric, and permitting said latex material to foam and cure. The latex foam has relatively fine mechanical open cells (18) in its internal part and further finer open cells (20) near its outer surface skin (22) which is permeable by virtue of minute holes (21) formed therein. The skin (22), though permeable by minutes holes, can serve as substantially flat and smooth barrier surface against liquid foamable mixtures poured directly onto said skin for making body foam (25) so as to guide slidingly said mixtures therealong and also prevent substantial impregnation into said latex foam.

Abstract: A method and apparatus for the manufacture of a diaphragm from a fabric-containing sheet (material). The fabric-containing sheet produced by an extrusion molding machine in a width which is a multiple of the diameter of diaphragms to be manufactured is continuously fed in fixed pitches to a press vulcanizing device and an punching device, to permit automation of the manufacture of diaphragms and an appreciable reduction in the number of steps. This method, thus, improves the yield of materials used, permits down sizing of the production equipment, and reduces the motive power consumption.

Abstract: A method for shaping thermoplastic fabrics such as those made of polyester or polyamide fibers into desired three dimensional configurations through a simple procedure. Thermoplastic fabrics are immersed into hot liquid metallic bath made of eutectic metals such as lead, tin, cadmium, zinc and bismuth and formulated to have the eutectic point at least equal to or higher than the softening point of the thermoplastic fibers and lower than the melting point of the fibers. This metallic bath may be called "fluidic lower mold." The thermoplastic fabrics are immersed into the fluidic lower mold by means of an upper mold or core member having desired outer configurations substantially corresponding to those of final products, for example, headrest or seat cushion. The upper mold pushes down the fabric preferably along with a protective sheet laid beneath the fabric into the metallic bath.
