Abstract: Synthetic biotextured surfaces and methods to produce the surface are disclosed. The surfaces mimic the topography of a surface of a naturally occurring sub-endothelial or sub-epithelial extracellular matrix. This is achieved by removing a cell layer from the naturally occurring extracellular matrix substrate, covering the extracellular matrix with a casting material, and allowing the casting material to harden. One then removes extracellular matrix from the casting material to uncover a negative core, and then uses the negative core to cast the replica material. By removing the negative core from the replica material one then creates the synthetic surface.

Abstract: Fiber reinforced resin composites formed of basic ply blankets is disclosed. The method of the invention uses design criteria, namely fiber orientation and fiber percentages in each orientation direction, to create a basic ply blanket having the same fiber orientation and percentage relationship. Specifically, a basic ply blanket comprises a plurality of plies, one in each fiber orientation direction. The fiber magnitude proportion that each blanket ply bears to the fiber magnitude of the blanket is based on the design criteria fiber proportion. The thickness of the basic ply blanket is divided into the design thickness at various locations and the results used to determine the number of blankets needed to meet the thickness requirement of the fiber reinforced resin composite at such locations. Basic ply blankets are then stacked to create the required thickness.

C. Accordingly, the hot side of the wall is lined with one or more liner blankets, each having a mineral fiber felt core, a metal foil front layer and a glass fiber fabric rear, supporting layer. These layers are quilted together and the result is provided with a binding about the periphery. The metal foil layer terminates somewhat short of the edge in order to make the margin more compressible. Each liner blanket is attached to the wall surface by a flexible adhesive. Where two or more of the blankets are used, they are placed so close together edge-to-edge that their respective margins are compressed, by abutment with one another preventing any unprotected gap.

Abstract: A method of producing a cleaning cloth having abrasive properties is disclosed.

Abstract: A process is disclosed in which a layer of textile fibers is applied to an expanded net formed from foils and consisting of two components, one of which is superimposed upon the other and one of which has a softening temperature substantially different from that of the other, and heating the layered structure thus formed to the softening temperature of the component having the lower softening temperature. The process is characterized by the fact that in forming the expanded net, the component having the lower softening temperature is spread sufficiently to cause it to tear into separate scales or flakes, some of which adhere to the higher melting component, and some of which adhere to the textile fibers.
