The heated bullet is then disposed in blended molybdenum disulfide and Nylon 11 powder, Nylon 11 per se, or other coating materials to obtain a coating thickness within a range of 1-12 mils. The coated bullet is subsequently heated to at least 367.degree. F. to fuse and to densify the coating on the bullet.Type: GrantFiled: October 26, 1978Date of Patent: May 11, 1982Assignee: Bangor Punta CorporationInventors: James L. Oberg, Roger J.

Patent number: 4315056Abstract: The application discloses a method of terne coating, and a terne coated product, wherein the tin content of the terne is substantially lower than in conventional terne, without the need for other alloying elements in substitution for tin, such as zinc, antimony, silver, and phosphorus. The tin content of the terne bath is lowered below conventional percentages, to between about 2% and about 6.5% and the terne coated product, upon emerging from the coating bath, is jet finished. Such a terne coat has improved solderability and appearance with no change in pinhole frequency. Coating weight control is easier than with a terne coat having 7% or more tin in the bath.Type: GrantFiled: February 4, 1980Date of Patent: February 9, 1982Assignee: Armco Inc.Inventors: Marvin B. Pierson, Frank C. Dunbar

Patent number: 4304822Abstract: Corrosion resistant coatings are applied to metal tubing while substantially continuously moving the metal tubing through a series of stations. The process comprises the sequential steps of flowing by gravity a zinc-rich thermosetting coating suspended in a volatile carrier onto the tubing, the viscosity of the coating composition being such that it flows around and completely covers the external surface of the tubing, removing excess coating by means of an air blower arranged circumferentially around the tubing and sequentially heating the coated tubing first to volatize off the carrier and then more rapidly to crosslink the thermosetting coating composition.Type: GrantFiled: June 4, 1980Date of Patent: December 8, 1981Assignee: International Telephone and Telegraph Corp.Inventor: Russell G. Heyl

Patent number: 4267241Abstract: A method of improving steel-backed antifriction alloy; composite strips and products therefrom, wherein the antifriction alloys previously deposited on the steel backing strip are subjected throughout the strip length to a spot-by-spot fusion operation performed by a highly-concentrated energy beam (electron or other), the intensity and displacement rate of said beam being adjusted in respect of the composite strip in such a manner as to afford a spot-by-spot fusion of the anti-friction alloys to a depth equal to the anti-friction layer thickness; and a method wherein concentration of said energy beam is adjusted so as to enable the mass surrounding any given melting spot to cause an abrupt cooling of said spot when the energy beam is moved to an adjoining spot.Type: GrantFiled: September 11, 1979Date of Patent: May 12, 1981Assignee: Metal Leve S.A.

Patent number: 4206268Abstract: A multi-layered plain slide bearing having a metal base layer, and having a slide layer which is carried by the base layer and which comprises a copper-lead-tin binary or ternary alloy that has been applied to the base layer and that has an unusually high cooper content. The slide layer can contain, by weight, from 20% to 70% of copper, at least 15% and at the most 80% of lead, and from 0% to 30% of tin, and can also optionally contain indium, cadmium or other like metals. The slide bearing can further include a run-in layer which covers the slide layer, and which contains copper, tin, indium and/or lead or their oxides, sulfides or phosphides.Type: GrantFiled: October 16, 1978Date of Patent: June 3, 1980Assignee: Glyco-Metall-Werke Daelen & Loos GmbHInventors: Erich Roemer, Fritz Niegel

Patent number: 4188079Abstract: A multi-layer metal bearing for use in a large-size engine or the like has three layers including a steel backing layer, a bonding or an intermediate layer of aluminum or aluminum alloy, and a bearing alloy layer consisting of more than 50% up to 65% by weight of tin, more than 0.5% up to 1.5% by weight of copper, and the remainder being essentially aluminum. The hardness of this bearing alloy at a relatively high temperature such as 100.degree. C. or higher is in the mid-range between that of the convention Al/Sn bearing alloy having 50% by weight or less of tin and that of the conventional white metal bearing alloy. This multi-layer metal bearing for use in a large-size engine presents a remarkably improved resistances against load and fatigue.Type: GrantFiled: February 22, 1978Date of Patent: February 12, 1980Assignee: Daido Metal Company Ltd.Inventor: Sanae Mori

Patent number: 4177326Abstract: The invention relates to a process and installation for making stainless els coated with a lead-based alloy and having undergone annealing. The surface of the product is first prepared by mechanical treatment, then the product is pre-coated by known techniques such as hot tin-plating, after which the annealing treatment is effected, followed by the final coating. Such products may be used, inter alia, in the manufacture of car radiators.Type: GrantFiled: December 16, 1977Date of Patent: December 4, 1979Assignee: VALLOUREC Usines a Tubes de Lorraine-Escaut et Vallourec ReuniesInventors: Bernard A.

Patent number: 4071643Abstract: This invention is the production of a plain bearing having an aluminum interlayer and a metal overlay on the interlayer. The overlayer is for example cast on the interlayer so that it can constitute substantially the final bearing surface without machining after casting or roll-bonding. In order to enable the overlay to be cast on, the interlayer is abraded while below the surface of a tinning or other coating material in a material so that oxides can be removed from the aluminium surface and the coating applied to it without its becoming re-oxidised, and then the overlay can be applied to the coating.Type: GrantFiled: November 20, 1975Date of Patent: January 31, 1978Assignee: The Glacier Metal Company LimitedInventors: George Christopher Pratt, Barry John Eastwood, Anthony Dennis Michael, Leonard Heath
