摘要： Machines and process for making in a continuous operation a prestressed glass reinforced, thermally insulating panel, structurally stiff, and totally impervious, of indefinite length and with a cross-section shaped as an elongated parallelogram.Steps for manufacture include making the surface of the panel out of a tubular envelope of knitted or woven glass fabric, stretched over a special holding frame, to give it the desired parallelogram shape. Fastened by a continuous knitting process to the opposite faces of the glass fabric envelope, other glass fibers are stretched inside the envelope and arranged according to three principal directions, all of them oblique with respect to the panel faces. The glass fabric envelope is then coated with a plastic resin to make it impervious to gas and covered on one face at least with a metal liner. This liner, made of cryogenic alloy, has its edges upturned and folded, so as to be fastened to the glass reinforced plastic envelope. Finally, the envelope is filled with a foamed-in-place thermal insulation, which, in expanding, surrounds each of the reinforcing glass fibers locked and held in a stretched position. Consequently, when released from the holding frame, after the foam has hardened, the relaxed tension of glass reinforcing fibers applies a compressive stress to the foam, directed normally to the panel faces. The oblique disposition of the reinforcing fibers is achieved by 4 knitting machines located in 4 non parallel spatial planes. The finished panels are used for constructing cryogenic tanks in LNG ships.

摘要： Two, endless, perforated steel belts are mounted one above the other to travel about spaced rolls, and between a pair of spaced, parallel, stationary side walls, so that confronting portions of the belts form two sides of an elongate, rectangular channel. Granules of thermoplastic material are continuously fed into one end of the channel in a quantity sufficient to completely fill the channel. The moving belts convey the granules first past a heating zone, where steam is introduced through the perforated belts to cause the granules to expand, and then past a cooling zone, where the granules are sintered to form a solid, rectangular block which is discharged continuously from the opposite end of the channel and onto a surface where it is severed into individual blocks. The diameters of the holes in the belts range from 0.5 to 0.8 mm., and the number of holes ranges from 20,000 to 30,000 per square meter of belt.

摘要： Polystyrene sheet is made by continuously expanding and autogenously joining discrete particles of polystyrene, the granules being arranged in a moving layer of uniform thickness through which a series of heating gases are blown. The sheet may be compressed. The first heating is to about softening without major expansion of the particles, the second accomplishes the expansion. Penetration by the hot gases of the forming sheet is assisted by vacuum. Cooling of the formed sheet is by flow of cooling fluid parallel to its surfaces.

摘要： A machine for continuous production of a strand of porous thermoplastic material from expandable, pre-expanded granules of said material by additional expansion and agglutination in a channel open at both ends and defined between opposed horizontal portions of two endless belts movable along closed paths under the action of heat from separate heating boxes adjacent said belt portions. To vary the height of the channel and therewith that of the strand advanced therethrough, the spacing between the opposed defining belt portions is variable. For rendering possible any desired variation of said spacing with as short break of operation as possible, the heating boxes project outside the belt portions and are here sealed from one another and from the sides of the channel between the belt portions by primary beams ridigly secured to the heating boxes and secondary beams exchangeably interposed between the primary beams. The secondary beams have varying height dimensions preferably according to a predetermined module permitting to assemble them to any desired height of the channel. The assembled beams form an interior face in the same vertical plane and their interior surfaces are preferably covered with a layer of friction reducing material.

摘要： A method for making a floor or wall panel has a foamed polymer core. A foamable polymer powder is foamed between two conveyor belts in the forming zone of a steel belt press. The sum of the thicknesses of the two conveyor belts and the total thickness of the layers at the entrance of the steel belt press is less than or equal to the opening of the steel belt press at the entrance of the steel belt press. The sum of the thicknesses of the two conveyor belts and the total thickness of the substrate at the outlet of the steel belt press is equal to the opening of the steel belt press at the outlet of the steel belt press and greater than the sum of the thicknesses of the two conveyor belts and the total thickness of the layers at the entrance of the steel belt press.
