Abstract:

A method and solution to activate and metallize the surface of a fluorocarbon material, suitable for circuit boards is disclosed. The surface of fluorocarbon materials is both hydrophobic and oleophobic, and highly inert and repellent to oils, dyes, adhesive and coatings. The method of the present invention makes such fluorocarbon materials wettable with metallizing solutions and chemicals, and also bondable with adhesives and coatings. The method comprises contacting said fluorocarbon surface with a mixture comprising a cyclic amide, a quaternary ammonium compound, a cationic or nonionic surfactant, a glycolether and an organic acid.

International Classification:

E04D 136

US Classification:

52 58

Abstract:

A composite roof covering securement element is comprised of an elongated rubber membrane onto which a plastic batten strip is adhesively bonded. The membrane and strip have a range of flexibility which permits the same to be rolled into a coil for manual prepositioning on a roof and then unrolled to lie flat upon the roof for attachment along the perimeter. When installed the composite element resists shear loads and securely retains the overlying roof covering in place.

International Classification:

F16B 4300

US Classification:

411531

Abstract:

A machine for fastening one or more layers of roofing material to an underlayment, and a stackable washer therefor. A chute receives a stack of such washers. A shuttle displaces a single washer to a separated position when moved in one direction, to which the shuttle is biased, releases the single washer when moved oppositely. A gate, which cooperates with camming surfaces on the respective washers, restrains the overlying washer in the stack against being displaced with the single washer and restrains the single washer from being displaced from the separated position. Various components are provided by linking a stand-up screw gun of a known type to the shuttle. The stackable washer is embossed so that each such washer and like overlying and underlying washers in a stack contact each other at three or more places, which define tangent planes intersecting planes defined by planar areas on such washers at angles more than 45. degree. but less than 90. degree. whereby such washers are spaced from each other around their entire peripheries.

International Classification:

F16B 2500

US Classification:

411387

Abstract:

A self-drilling fastener for use with medium density wood panels, such as oriented strand board (OSB), having a head and first and second shank portions where the first shank portion includes threads for mating engagement with an OSB panel and the second shank portion substantially is formed as a taper shank flat drill which forms the drilling end of the fastener, the taper shank flat drill having conical shaped tapered portions, a triangular drill tip and a pair of wing portions formed on opposite sides of the flat drill forming helical cutting edges.

Michael P. Ditka - Deerfield IL

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

F16B 3300

US Classification:

411368

Abstract:

A composite fastener comprised of a roofing screw and a roofing washer. The screw shank has a leading portion, which is threaded, and a locking portion. The locking portion has a substantially frusto-conical part adjoining the leading portion and an additional part adjoining the screw head. The substantially frusto-conical part defines a major diameter where it adjoins the additional part and a minor diameter where it adjoins the leading portion. Two locking tabs extend from the substantially frusto-conical part, in diametric opposition to each other, in such manner that an imaginary cylinder coaxial with the shank and with a diameter equal to the major diameter divides each tab into a proximal part inside the cylinder and a distal part outside the cylinder. The washer has an aperture with a margin that flexes the tabs to allow the tabs to pass through the aperture.

International Classification:

F16B 1500

US Classification:

411439

Abstract:

An anchoring device having a head and a shank to be forcibly driven into a hole defined within concrete or is disclosed. The shank has proximal, transitional, and distal portions defining respective axes that do not coincide when the shank is unstressed and further defining proximal and distal elbows. Notches enhancing frictional engagement between the shank and the hole wall are formed along convex surfaces of the elbows, as well as long substantially cylindrical surfaces of the proximal, transitional, and distal portions of the shank.

Abstract:

A shuttle displaces a single washer to a separated position when moved in one direction, to which the shuttle is biased, and releases the single washer when moved in the opposite direction. A gate, which cooperates with camming surfaces defined upon the respective washers, restrains the overlying washer within the stack against being displaced along with the single washer and restrains the single washer from being displaced from the separated position.

International Classification:

B25B 2306

US Classification:

81 5737

Abstract:

In a machine for dispensing stackable roofing washers individually and for driving fasteners through such washers, a shuttle is actuatable to displace a lowermost washer of one from a stack, either a small, circular or large, square washer. A gate is biased toward a lowermost position wherein it provides sufficient clearance for the lowermost washer but not any overlying washer to pass beneath it. A pawl mounted pivotally to the gate is biased to a lowermost position wherein the pawl engages a small washer displaced by the shuttle so as to restrain it against backward movement. A stop is adjustable so as to limit movement of a washer of whichever size is being displaced. A measuring bar is mounted via the stop. A screw gun, which provides a primary handle, and a secondary handle are mounted to an upright element so as to be independently adjustable.
