A plurality of flutes are formed into the first and second face surfaces of the core metal insert in an undulating pattern, and extend between the first and second edges such the core metal insert is corrugated. The corrugation of the core metal insert separates the first and second face surfaces by a distance greater than the original thickness of the core metal insert. A method of providing such a core metal insert also is provided.

Abstract: A metal sheet member for insert molding with a plastic member is disclosed having a plurality of bonding portions arranged on the top wall thereof for enhancing the bonding strength of the plastic member to the metal sheet member, each bonding portion including a groove located on the top wall of the metal sheet member and a lug formed of a part of the metal sheet member and obliquely upwardly curved from one end of the groove.

Abstract: Disclosed are environmentally friendly coating compositions for coating thermoplastic olefin objects and which are curable using ultraviolet and visible radiation. Even if the coating compositions are applied to an unprimed surface, the resulting cured compositions have excellent adhesion. The cured coatings have improved adhesion properties and clear coat embodiments have improved clarity properties. In addition, methods are disclosed for coating surfaces, or at least a portion of the surfaces, and curing of the coated surface to obtain partially or fully cured coated surfaces are also disclosed. Furthermore, articles of manufacture incorporating fully cured coated surfaces are disclosed, including, for example motor-vehicle bumpers. Also disclosed are methods, processes, production lines, articles of manufacture, and factories which incorporate these environmentally friendly coating compositions.

Abstract: An article of manufacture forms a tool for determining cleaning parameters of an oxide removal process. The article comprises a block of material upon which an oxide can be formed and a simulated defect structure disposed in the block of material. The article is capable of determining oxide removal parameters of an oxide removal process by disposing an oxidized standard in a reactor, conducting an oxide removal process to remove oxide from the standard, and evaluating the standard and simulated defect structure for remaining oxide and other oxide removal parameters.

Abstract: A cutable topcoat composition and apparatus useful for preparing stable data carrying devices, such as multi-layered laminates, and methods for preparing and using the composition. The composition includes a polymerizable composition and a polymeric binder. The polymerizable composition includes hard and flexible polymerizable subunits in a ratio that optimizes flexibility while retaining good adhesion and plasticizer resistance. In a preferred embodiment, a polymerization initiator is also included in the composition. Optionally, a chain transfer agent may also be added to the composition. The composition is substantially plasticizer free. The methods of using the composition include incorporating the composition into a topcoat film useful for storing the topcoat composition prior to use in preparing data-carrying devices, such as cards.

Abstract: There is disclosed a reinforcing element for reinforcing a solidified fluid mass such as concrete or refractory comprising an elongate shank having a slot extending along at least a portion of the length of the shank. The slot increases the surface area of the shank and increases the aspect ratio of the element to more firmly bond the element in the mass. Anchoring portions are provided at the ends of the shank and have a width greater than the diameter of the shank.

Abstract: A thermomorphic covering layer is applied to a heat-shrinkable body of thermoplastic material, e.g. a heat-shrinking sleeve adapted to surround and seal a cable splice so that when the heat-shrinking temperature is reached, the thermomorphic covering melts to form a continuous protective layer on the sleeve. It contains glass fibers or an insecticide or microbicide to protect the sleeve against pest deterioration.

Abstract: A continuous strip of sheet metal is progressively sheared with longitudinally spaced and laterally extending slits to form opposing U-shaped tabs having corresponding edge portions and successively connected by corresponding center portions of the strip. In one embodiment, the sheared strip is fed between first and second overlapping sets of power driven pinch rollers which progressively grip the edge and center portions, respectively, and the second set of pinch wheels is longitudinally offset and driven at a higher peripheral speed to produce precisely uniform expansion of the strip by deforming the U-shaped tabs into V-shaped tabs. A hot melt adhesively impregnated flexible filament is progressively attached to the expanded center portions of the strip while the strip is heated to form a continuous center connection. In another embodiment, the strip of opposing U-shaped tabs is expanded into opposing V-shaped tabs by coining or thinning a connecting center portion of the strip.

Abstract: A photographic support having an undercoating layer on a resin coated base sheet, said undercoating layer comprising (a) a hydrophilic colloid, and (b) a special amphoteric surface active agent, or (a) a hydrophilic colloid, (b') a p-hydroxybenzoic acid ester and/or a special amphoteric surface active agent and (c) a special isothiazoline-3-one compound, provides excellent coating and adhesive properties to a photographic emulsion layer formed on the undercoating layer.

Abstract: An extruded section bar member for use as a vertical support in furniture, particularly in industrial and office furniture, comprising a cross section corresponding to an elongated rectangle with rounded edges and including T-grooves recessed into its long sides for receiving fastening elements.

Abstract: The subject invention involves the design and construction of a tubular cylinder for use with other components and in which the wall of the cylinder is of a composite character made into a unitary structure and provided with a multitude of substantially radial holes in its periphery and a predetermined amount of a cylindrical surface of the wall is preferably cut away to fully open the holes whereby to provide passages through which a material to be processed and under pressure in the cylinder can be forced or extruded outwardly through the passages and thereby condition the material for its intended use.

Abstract: A structural member comprising a flat strip of web of material having a plurality of slots formed at spaced intervals along each edge of the strip, the inner portion of each slot being of greater dimension than the outer portion and formed to the desired degree of curvature in the plane of the strip.

Abstract: An electromagnetic interference (EMI) shielding device for use in supporting members that receive enclosure covers of electrical or electronic instruments. The EMI device comprises an L-shaped strip of metal having first contact means which maintain the device in position in a groove in the supporting member and provide electrical contact therewith and spring contact means against which an edge of an enclosure member disposed in the groove engages thereby providing electrical contact therewith and securely maintaining the enclosure member in position.

Abstract: This invention relates to an improvement in a drawing layer for a plastic film, in particular for a polyester film, said drawing layer being adherent to the film and comprising a cellulose ester crosslinked by a formaldehyde resin, and including a matt-finishing agent and/or a pigment, the improvement which comprises that the drawing layer additionally contains at least one copolymer containing maleic anhydride units.

Abstract: A flexible string of interconnected sheet metal clips of the type which are adapted to hold the end bars of a sinuous or zigzag cushion-supporting springs on the wooden frame of an article of furniture. The clips are disposed in side-by-side relationship and adjacent clips in the string are connected together by a thin flexible web, the thickness of which is reduced by a swaging operation, and which serves to maintain such clips slightly spaced apart.
