Abstract: A composite structure and method therefor comprises a metal surface which is coated with a polymer incorporating a bidentate chelating functionality. The polymer provides significant and varied chemical modification to the metal surface and is useful, for example, as a protective coating or a priming layer. Bidentate chelating monomers useful in preparing homopolymers and copolymers with ethylenically-unsaturated non-chelating monomers have structures described by the formula ##STR1## in which R.sup.1 is hydrogen, lower alkyl, chlorinated lower alkyl, CN, or ClP is a connecting linkage of chain length up to to about 75 atoms, andQ is a bidentate chelating group having a high affinity for the ions of the metal of the surface involved.

Abstract: Anaerobically-curing compositions are described comprising (A) a polymerizable monomer; (B) a halogen-containing compound as a first initiator component; (C) an amine, organic sulfimide or perfluoroalkyl sulfonanilide as a second initiator component; and (D) an inhibitor of free-radical polymerization. These compositions are particularly suitable as adhesives and may be formulated as thread-locking adhesives or may be modified by the addition of various modifying polymers to obtain desired properties such as increased viscosities or pressure-sensitive properties.

Abstract: A cable tie system for simultaneously assembling and applying cable ties from a continuous length of strap material and a plurality of individual cable tie heads. The cable tie heads are molded of plastic with a pair of parallel cable tie strap passages and a metal pawl retained in the plastic between the two passages and having pawl teeth that project into each of the strap passages to engage the strap material at two spaced positions when it is slid through one of the passages around a bundle of wires and into the second of the passages.

Abstract: A thin film magnetic recording playback head is disclosed wherein mechanically coupled films of a magnetostrictive material and of a piezoresistive material are utilized with a solid state amplifier electrically coupled to sense resistance changes in the piezoresistive film. In operation, localized magnetic patterns on a recording medium induce strain in the magnetostrictive film, which in turn induces in the piezoresistive film corresponding changes in electrical resistance.

Abstract: A cover assembly for use with a disk-shaped optical recording medium, having two substantially identical halves, each having an inner surface adapted to provide upon assembly with the medium an air gap adjacent an optical recordable coating on the medium. Each cover half is transparent and has substantially no birefringent characteristics on the region overlying the air gap, thus allowing light to pass unimpeded therethrough. The cover assembly is adapted to be coupled to the central hub of the optical recording medium and to have a raised annulus adjacent thereto to support the assembly and minimize contact with the transparent portion.

Abstract: A desensitizer apparatus for use with magnetically based electronic article surveillance systems having a marker containing at least one magnetizable section which when magnetized, alters the response of the marker produced by an alternating magnetic field provided in an interrogation zone. The apparatus includes a magnet assembly having an elongated permanent magnet section and a pair of elongated pole pieces which concentrate external fields produced by the magnet sections near a gap extending the length of the magnet section, the external field near the gap being sufficient in intensity to magnetize the magnetizable section of a marker positioned proximate thereto, and being rapidly attenuated a short distance from the gap. Accordingly, magnetically sensitive articles such as prerecorded magnetic recording cassettes to which the markers are affixed are not affected.

Abstract: Abrasion resistant films formed by the copolymerization of epoxy-terminated silanes and limonene monoxide display water repellency that reduces damage to the integrity of the film.

Abstract: Articles having on one surface thereof a linear prism array and a diffraction grating on the opposite surface are provided which are suitable for the preparation of projection transparencies.

Abstract: A method of repairing damage to the sheath of a communications cable in which a heat shrinkable material is wrapped around the communications cable to bridge across the damaged area of the sheath. A flexible strip heater having a base with a heating element in a portion of its width and a parallel insulating layer overlying only a portion of the base is wrapped in a spiral around the heat shrinkable material with the portion having the insulating layer wrapped on the portion of the previous turn not having the insulating layer. The insulating layer substantially abuts itself in adjacent turns of the heater to position the portions of the base containing the heating element adjacent each other along the heat shrinkable material. The heating element is activated to cause the heat shrinkable tape to shrink tightly onto the communications cable to cover the damaged portion of the sheath and, the flexible strip heater is then removed.

Abstract: Energy is saved during the drying of radiographic films by infra-red radiation devices if their power is automatically varied in accordance with temperature measurements taken on circulating air. Such devices are particularly useful if incorporated into aqueous bath photographic processing machines which are followed by a drying chamber.

Abstract: An electrical wire connector having a hollow, open-topped insulating body, an insulating cover formed to telescope with the body, the body and cover having complementary latches to retain them in an open position for insertion of wires into wire receiving channels in the cover and also to retain them in the closed position fully telescoped together. A slotted, flat plate wire connector element is retained in the body for connecting two wires supported in the channels in the cover upon telescoping of the cover and body together. At least one of the wire receiving channels is open-sided for insertion of a wire transversely into the channel when the body and cover are in their open position, and at least one deformable resilient finger is provided at the outer edge of each open-sided channel.

Abstract: An electrically operated copy machine capable of producing continuous copies of extended length originals is provided with a control switch which allows copying to be stopped at any position along the original and then allows either the copy to be cut and copying discontinued or the repositioning of the original and the continuation of copying at a different portion of the original.

Abstract: Silver halide photographic elements comprising a support on which there is spread a plurality of photosensitive layers of gelatin incorporating silver halides and containing coupling agents, and further being associatd with auxiliary gelatin layers tend to suffer from brittleness.
