Abstract: Synthetic suede leather is produced by casting a mixture containing polyurethane elastomer and a solvent therefor between two sheets of a substrate fabric, immersing the resulting structure in a liquid which is a nonsolvent for polyurethane elastomer but miscible with said solvent, splitting said structure into two sheets at middle of the cast layer before it is fully gelled, and re-immersing the resultant sheets in said nonsolvent to allow complete gelation of said mixture.

Abstract: A label is applied to a cup by superimposing a foil tape on a label tape that has a plurality of transverse breaking lines. The tapes are heated to "floatingly" connect the label tape to the foil tape and are then introduced into a deep-drawing apparatus so that the punch thereof may cyclically sever a single label and at the same time form a cup. If the breaking line is fed to the longitudinal axis of the deep-drawing apparatus, the label will be applied to two sides of the cup. If the label tape is fed so that the breaking line is approximately at the far edge of the deep-drawing apparatus then the label will be applied to only one side of the cup. The label tape may be longitudinally slit so that a plurality of cups may be simultaneously deep-drawn.

Abstract: Apparatus for and method of manufacturing a heat insulating material from an uncured, strip-shaped felt of fibres containing a heat hardenable bonding substance firstly form corrugations extending across the entire width of the uncured felt and following one another in succession along the length of the felt. The corrugated felt is then cured as a cured felt containing fibres extending in a serpentine array along the felt, and conveyed along a path of travel extending past a cutter having a cutting blade extending transversely across the path, whereby the felt is cut longitudinally into two partial felts, the corrugations being severed so that the fibres form U-shaped arrays disposed in succession along each of the partial felts. This fibre array provides compressive strength combined with flexibility, enabling the insulating material to be used on various pipe sizes.

Abstract: The invention relates to a method of manufacturing surface elements such as tiles or panels consisting of a thin lamina of natural stone bonded to a backing consisting of a multicellular paper core material of substantially greater thickness than the lamina which at least on the side remote from the stone lamina has a skin of tenacious sheet material bonded thereto. The method comprises bonding the backing to a stone slab and thereafter severing from the slab a thin lamina of stone with the backing attached.

Abstract: The invention contemplates expanded-plastic coated fabric wherein the exposed surface of the expanded plastic is characterized by a random distribution of torn cellular pockets and by a random distribution of projecting free ends of flock elements which are rooted to the plastic at their other ends. Various methods of making the fabric are described, with different "hand" or "feel" depending upon the method and upon the materials and their dimensions.

Abstract: Two warp sheds are formed from warp threads at least some of which are meltable. The warp threads are preheated to make them deformable and weft threads are inserted into the respective sheds and beaten-up in order to form two superimposed fabrics which are connected by the meltable warp threads. During the beating-up the weft threads and the meltable warp threads are simultaneously heated so as to make them adhere to one another. The resulting fabrics are cooled to reverse the deformability of the meltable warp threads, and thereupon the latter are severed intermediate the fabrics by application of heat while the severed ends of the meltable warp threads are simultaneously deformed.

Abstract: Method for laying flooring on a solid sub-floor comprising the step of coating the sub-floor with a loose intermediate layer, screeding and thereafter covering the intermediate layer with a pressure distributing layer of semi rigid or rigid plates, whereby the intermediate layer consists of sawdust which has been sifted in order to remove particles having a size exceeding 5 mm and which have improved slender values by having been cut and split substantially along the grain, the sawdust being spread on the sub-floor, screeded to a thickness of 5-25 mm, and covered with the plate material which may be coated with an outer or wearing layer.

Abstract: A process for preparing a mold for relief printing masters, said mold having an adhesive silicone surface, is provided comprising depositing a particulate material in image configuration on a suitable substrate, contacting said substrate with a second member comprising a substrate with an adhesive coating of a silicone gum curable to an adhesive elastomeric condition such that the adhesive gum is in contact with the image material, separating the members whereby the silicone layer splits in the nonimaged areas and is prevented from splitting by the transfer of the particulate image material to the second member in the image areas, and curing the silicone gum on the first member to an adhesive elastomeric condition to provide a mold for printing masters.

Abstract: Disclosed is a process for manufacturing elastic floor covering boards comprising a lower, water-permeable layer of natural or synthetic rubber particles bound together by an adhesive and a cover layer of non-woven synthetic textile fibers, which process comprises placing into a mold the cover layer of non-woven synthetic textile fibers, impregnating this layer with a resilient, heat-curable adhesive, placing the particles of natural or synthetic rubber which are likewise impregnated with said adhesive on top of the fibrous layer and subsequently compressing both layers in the mold at a temperature below 100.degree.C. and at a pressure of from 40 to 100 metric tons per square meter until the adhesive is cured. Advantageously, a woven reinforcing layer is interposed between the two layers prior to molding to provide an exceptionally strong and stable product.

Abstract: A plastic container for food products and method of making the container, the body of the container thermoformed from a sheet comprising a plurality of layers which are held together in a contiguous structure without being securely bonded together, said layers of the container body functionally secured in place after filling by an interlocking closure. At least one layer provides structural rigidity and a good water vapor barrier and at least one other layer provides a barrier to the transmission of oxygen and a supplementary water vapor barrier. The container is capable of withstanding retort temperatures. Separation of the scrap sheet from which the container body is formed and recycle of separate layer scrap from the container body thermoforming process can be accomplished since the layers forming the container body are not securely bonded together.

Abstract: An oil painting is simulated by gluing a photograph onto a textured surface, rolling the photograph with a nubby roller to force portions thereof into the voids of the textured surface and sealing the photographic surface thereafter in a manner to simulate an artist's brush strokes.

Abstract: Solid gas-permeable synthetic polymeric articles are chemically filled with a filler compound formed in situ. These deposits are produced by diffusing one or more diffusion compounds into a solid gas-permeable polymer and reacting or decomposing the diffusion compound(s) to form deposits throughout the article. The compounds may be preferentally deposited in a planar zone of sheet material in an amount sufficient to cause the sheet to split.
