Abstract: A padlock having a lock body defining an interior cavity includes a locking mechanism operably disposed within the inner cavity. A shackle is releasably lockable to the body in the closed position for securing an object, and movable to an open position for receiving and releasing the object. A protective sheath is attached to the shackle so as to substantially encase exposed portions of the shackle in the closed position. The sheath defines a closed space between the sheath and the lock body for securing an object, and is movable with the shackle into an open position for receiving and releasing the object.

Abstract: A foot strap assembly for wader boots is provided whereby a foot and leg may be more securely held within the wader boot preventing the boot from becoming stuck between rocks or mud which may cause injury to a boot wearer. The foot strap assembly includes an adjustable leg strap which encircles an upwardly extending portion of the wader boot, an adjustable foot strap which extends downwardly from the leg strap to underlie the bottom of the wader boot, an adjustable front strap which is tethered to the leg strap and which encircles the front portion of the boot. The foot strap assembly is positioned around the outside of the boot and adjusted to hold the foot securely within the boot. Adjustable rear straps extending from the leg strap to the foot strap, and beyond to front strap, may be used for further support.

Abstract: A primed film comprises a polymeric film substrate layer having an adherent layer comprising a copolymer comprising comonomers (a) 35 to 40 mole % alkyl acrylate, (b) 35 to 40 mole % alkyl methacrylate, (c) 10 to 15 mole % of a monomer containing a free carboxyl group, and (d) 15 to 20 mole % of an aromatic sulphonic acid and/or a salt thereof. The primed film can be used, for example, for producing metallised films, drafting films, photographic films and magnetic cards.

Abstract: A thermal transfer printing receiver sheet for use in association with a compatible donor sheet, the receiver sheet comprising an opaque polyester supporting substrate having a deformation index, at a temperature of 200.degree. C. and under a pressure of 2 megaPascals, of at least 4.0%, the substrate having, on a surface thereof, an adherent layer comprising an acrylic resin and having a coat weight within the range from 0.05 to 10 mgdm.sup.-2, the adherent layer having, on a surface thereof remote from the substrate, a dye-receptive receiving layer to receive a dye thermally transferred from the donor sheet.

Abstract: A graft copolymer having a diene rubber substrate and a superstrate which is a homogeneous copolymer comprising acrylonitrile and aromatic olefin, the diene rubber substrate and the superstrate having refractive indices differing by less than 0.008 from each other and from that of a homogeneous acrylonitrile/aromatic olefin resin with which the graft copolymer may be subsequently blended, the resin containing units of acrylonitrile within the range 86 to 93 percent molar.
