Abstract: A tarpaulin or other similar protective cover of flexible sheet material is adapted to be tied down securely with the aid of a single tie-down line extending around its periphery. The periphery is edge-finished with a continuous hollow conduit laterally fluted at equally spaced intervals with identical semi-circular cut-outs deep into the hollow conduit. Each cut-out defines a hole in the conduit wall which, in use of the tarpaulin with a tie-down line loosely contained in, and longer than, the conduit, permits a length portion of the line to be pulled outwardly from the conduit in a looped configuration for anchoring attachment to a respective tie-down device. Tearing of the tarpaulin by anchoring forces exerted thereon by way of the single tie-down line is effectively resisted, notwithstanding the absence of grommets or other relatively expensive reinforcement measures.

Abstract: A recreational towel type device specifically designed for absorbing moisture and use as a ground or furnishing cover, capable of being secured to the covered surface and further being capable securing other objects is provided.

Abstract: The invention concerns a gypsum construction board in which a gypsum core is faced with a two-layer laminate comprised of a nonwoven fiber felt and a glass fiber web of crossed glass fibers wherein the glass fiber web of crossed glass fibers is embedded in the gypsum core and the laminate is in the form of a laminate sheet which extends across the width of the board.

Abstract: The invention relates to a bottleneck foil consisting of an aluminum foil section provided on at least one side with a special protective layer which comprises 1-40 percent by weight of a binder which is not resistant to alkaline solutions and 60-99 percent by weight of a binder which is resistant to alkaline solutions.

Abstract: A longitudinally divided cable sleeve having a strip-like sleeve member composed of thermo-plastic synthetic material having a memory shape characterized by the slot between the edges being covered by either the longitudinal edges being overlapped with respect to one another or one of the edges having an overlapping extension and with at least one of said edges having a mechanical reinforcement so that the edges are more thermally stable than the remainder of the strip when subjected to heat for shrinking the sleeve onto an object. The reinforcements may be completely embedded into the material of the strip, partially embedded or placed on outer surfaces thereof. Preferably, the reinforcements also support or provide interlocking connecting elements such as hook and catch elements for securing the edges together and the connection elements aid in taking up the shrinking force created during the shrinking operation.

Abstract: The formation of articles using an elongated strip which has on it a series of longitudinally positioned upstanding ribs to form between them a series of longitudinally positioned channels and including connectors on the strip spaced apart transversely on the strip whereby the strip can be wound helically to form an elongated object with the connectors interengated along a helical line to lock the strip in object form.

Abstract: The magnetic anisotropy field in a layer of magnetic material on a substrate is determined by a method involving the application of a magnetic field upon whose release a so-called "sea of bubbles" is observed. The direction of this field typically is at a nonzero angle of elevation relative to the layer.In accordance with the invention, a preferred angle of elevation is determined upon inspection of a functional relationship between angle of elevation and magnetic field strength associated with the observation of a sea of bubbles. Results obtained by the method compared favorably with results obtained based on magnetic resonance techniques and, since the method is also relatively simple, it is particularly suitable for quality control in the manufacture of magnetic bubble devices.

Abstract: A splicing unit for integrally joining ends of seal strip material to form a continuous annular seal ring comprises two reinforced elastomeric ply strips with an unreinforced elastomeric gum interposed between them to form an H-section configuration, the length of the unit being substantially the width of the seal strip while the thickness of the gum between the ply strips is substantially the thickness of the seal material to be joined. The ends of the seal strip are inserted between the legs of the H-section on either side of the unreinforced gum and cured to form the integrally spliced seal ring.

Abstract: A service cloth having on its top side patches of hook fiber cloth, and bags containing weight material, each of the bags having on one side thereof a patch of hook fiber cloth, the hook fibers of the patches on the bags being pressed into intermeshing and interlocking engagement with the fibers of the patches on the top of the service cloth, the hook fibers being yieldable and resilient to permit such engagement and to permit disengagement upon the application of sufficient force. Also the provision of a flap portion of the service cloth which is foldable over the body of the cloth and attachable, in the same manner, to provide a pocket.

Abstract: A generally elliptical cylindrical metal substrate, and a method of construction thereof. A plate mandrel having a generally rectangular cross section is provided, and a first end of a web of metal substrate material is affixed to the plate mandrel. The metal substrate material preferably comprises alternate layers of planar metal foil and corrugated metal foil. As an alternative, a corrugated metal foil may be substituted for the planar foil. The metal substrate material web is wrapped around the mandrel, as by rotation of the mandrel while the web is fed off of a spool, until a substantially uniform thickness of metal substrate surrounding the mandrel is provided, a generally elliptical cylinder being formed. A second end of the web is affixed to a previous wrapping, thus forming a complete elliptical cylindrical metal substrate. The metal substrate is preferably catalyzed and used as a catalytic muffler or the like.

Abstract: This specification discloses a process wherein by applying certain controlled homogeneous precipitation techniques in the presence of a homogeneously distributed finely divided particulate supporting material, there is effected a deposition precipitation of a metal or metal compound on the surfaces of the support particles. This deposition precipitation process may be effected in a number of ways, such as by homogeneous changes in the pH of the solution, or decomplexation to an insolubilizable metal ion, or introduction of the metal component to be precipitated, or oxidation or reduction techniques, or by introduction of precipitating ions, etc.

Abstract: An absorbent facing material comprising 10 to 30% cellulosic, staple length, textile fibers, 60 to 80% of fluff wood pulp, and 5 to 25% of a resin binder material. The cellulosic fibers are substantially only on one surface of the material and the wood pulp substantially only on the opposite surface. The binder is distributed in a predetermined pattern with the surface containing the cellulosic fibers having a higher concentration of binder than the surface containing the wood pulp fibers.
