nickel alloy containing 5 to 15% by weight of cobalt, wherein the wire is prepared by electroplating a layer of nickel or a nickel alloy containing 5 to 15% by weight of cobalt on a nickel-titanium alloy wir.:, heating the plated wire at a temperature of 350 to 750°C for a time sufficient until a hydrogen content of the plated wire is rc- duced to below 10 ppm, cold working the plated wire at a working ratio of at lea\t 10%. and heating the cold-worked wire at a temperature of 300 to 900°C for 10 to 120 sec.

Special Effect Paint for Motor Vehicles U.S. Patent 5,733,976. Mar. 31, 1998 M-T Sailer, assignor to Daimler-Benz AG, Stuttgarf, Germany

An effect paint comprising a homoge- neous mixture of at least one liquid crystal side-chain polymer with mesogenic unit<, and at least one surface-active compound, which automatically aligns the mesogemc units in the chiral-nematic arrangement during paint application to produce a di:%- tinct color effect.

Electrostatic Coating System U.S. Patent 5,735,958. Apr. 7, 1998 F: Mauchle, assignor fo Gema Volsfafic AG, Switzerland

Removal of Paint from Wheel Hubs U.S. Patent 5,735,965. Apr. 7, 1998 K Baldi, assignor to Reynolds Wheels International Lid., Lugano, Switzerland

A method of removing paint, in partic- ular electrostatically applied powders from wheel hubs, comprising blocking the hub from one side to form a chamber;

generating a jet of air into the chamber to contact the hub surface directly, indi- rectly, or obliquely with the air and pro- duce turbulence sufficient to remove an unwanted layer of paint covering the hub surface; and generating a negative pres- sure in at least part of the chamber re- ceiving the jet of air to aspirate and re- cover the paint removed from the hub and held in suspension by the air in that part of the chamber.
