Abstract: The present invention pertains to the problem of compressing biomass, e.g., ripe grain or cereals, into solid pressed bodies 1, which are suitable for use as fuel, despite differences in the harvesting conditions, and whose strength no longer depends on the moisture content in the biomass. It was found that this problem can be solved without an essential expense by imparting a wavy structure 6 to the pressed body 1. As a result, the outer surface of the pressed body 1 is compressed more strongly by the extrusion than is the middle cross section area, in which long-fibered parts of the mass are readily oriented in a wave shape 21 and lead to elasticity of the pressed bodies 1, which is favorable for handling.

Abstract: A reusable cleaning cloth for damp and dry cleaning of surfaces. The cloth is made of a textile base layer of non-woven fibers and, on the surface that provides the cleaning action, a plurality of filament loops which project out of this surface. The filament loops are concentrated in spaced apart surface regions separate from one another, like islands, by non-linear border lines delineating channels that are essentially free of filament loops. In its finished form, the island-like areas with the filament loops project 0.5 to 5 mm out of the base surface. The islands are aligned to be equidirectionally staggered relative to one another, each having a length of 4 to 50 mm with a corresponding width of 2 to 10 mm. The channels which separate the islands are as broad as one to two of these islands in the region between the adjacent long sides of the islands and narrow in the region of the adjacent ends of the islands.

The cylindrical filter has an excellent filter rating and filter life.

Abstract: The present invention relates to an improved loop portion of a hook and loop fastening system. The loop portion is a two-layer composite including a compressively resilient backing material and a layer of fibrous loop material. The loop material is placed adjacent the bottom surface of the backing material and then a plurality of the loop fibers are needled or stitched through the backing material to form a plurality of loops which project above the top surface of the backing material. Due to the resilient nature of the backing material, when a hook member is brought into engagement with the loop material, the backing material compresses thereby exposing a greater portion of the individual loops for engagement with the hooks. Once the hooks have been engaged, the backing material expands back to make the exposed portion of the loops smaller.

The belt has a canvas core layer, an elastomer layer outside of the canvas core layer, a surface canvas layer that is expansible lengthwise of the belt outside of the elastomer layer, and structure applied on the surface canvas layer and exposed on the outside surface of the endless belt to resist bonding of foreign material thereto.

Abstract: A high visibility fabric includes a web of fibrous material and a fluorescent layer. The web has first and second major surfaces, and the fluorescent layer includes fluorescent pigment in a crosslinked resin. The resin penetrates into the web to surround the fibers and is bonded thereto, but the fluorescent pigment is concentrated at the first major surface at a level greater than at the second major surface. Because the pigment concentrates at the one surface, considerably less pigment is used in producing a fluorescent colored fabric. The fabric can be used to form a safety vest, and retroreflective sheeting can be placed on the vest to further enhance visibility.
