A63B 5304

US Classification:

473349, 473345

Abstract:

A golf club is made of a club shaft and a club head. Either the club shaft or the club head is made at least in part of a bulk-solidifying amorphous metal. A preferred bulk-solidifying amorphous metal has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel, plus incidental impurities, the total of the percentages being 100 atomic percent. The weights of the various club heads of a set, which have different volumes, may be established by varying the compositions and thence the densities of the bulk-solidifying amorphous alloys.

International Classification:

B23K 3522

US Classification:

148528

Abstract:

Two pieces of metal are joined together using an amorphous metallic joining element. In the joining operation, the joining element is placed between the two pieces to be joined. The joining element and adjacent regions of the pieces being joined are given a joining processing sequence of heating to a joining temperature, forcing the two pieces together for a period of time, and cooling. The joining element has a composition that is amorphous after the processing is complete. The joining element composition is also selected such that, after interdiffusion of elements from the pieces being joined into the joining element during processing, the resulting composition is amorphous after cooling.

Abstract:

A hard-facing material source is an article whose net composition is, in weight percent, from about 20 to about 35 percent chromium, from about 2 to about 5 percent boron, from about 1 to about 2. 5 percent silicon, from 0 to about 0. 5 percent carbon, from about 0. 5 to about 2 percent manganese, and from about 0. 2 to about 1. 0 percent titanium, balance iron and incidental impurities. The article may be a powder or a hollow tube with a powder packed therein. The hard-facing material source is thermally applied to a substrate by spraying or welding.

International Classification:

H02K 1100

US Classification:

318257

Abstract:

An improved hoist control system wherein a D. C. motor is employed to drive the hoist, and a remote hand-held control is utilized to vary the motor speed and direction of rotation. The hand control comprises an A. C. to D. C. variable transformer which is controllable by a trigger mechanism, a three-pole double throw switch for up-off-down control of the motor, circuit on-off switches, a meter for reading the hoist load, and an interlock device for limiting the actuation of the motor control switch if the trigger is depressed.

US Classification:

277 9

Abstract:

A joint includes two members with facing surface sections sealed together by a meltable seal material contained within a reservoir between the surface sections. A non-capillary recess in one of the members adjacent one surface section keeps the seal material from flowing out of the reservoir between the members by capillary action when the seal material is melted to form or reform the seal between the members.

Abstract:

A nickel tungsten-containing coating is electrodeposited onto a substrate from an electrodeposition bath having in solution from about 0. 034 to about 0. 047 moles per liter of nickel, from about 0. 15 to about 0. 28 moles per liter of tungsten, from about 0. 13 to about 0. 43 moles per liter of hydroxycarboxylic acid, and 0 or from about 0. 077 to about 0. 15 moles per liter of boron. The bath has a pH of from about 6 to about 9, and the electrodeposition is preferably accomplished at a temperature of from about 100. degree. F. to about 140. degree. F.

International Classification:

C25D 510

US Classification:

428678

Abstract:

A process for protecting an article from wear, wherein a frictionally transformable material is provided at the surface of the article, and then the surface of the article is subjected to frictional wear. The wear transforms the outermost layer of the material to the amorphous state, which is more wear resistant and corrosion resistant than is the material in its nonamorphous state. As the material is worn away gradually, the frictional transformation continues, thereby replenishing the amorphous outermost layer, so that a protective outermost layer remains. A particularly satisfactory frictionally transformable material consists essentially of from about 40 to about 75 weight percent of a first component selected from the group consisting of iron, cobalt, and combinations thereof; more than about 20 weight percent of a second component selected from the group consisting of chromium, molybdenum, tungsten, niobium, vanadium, and combinations of chromium, molybdenum, tungsten, niobium, vanadium, and titanium; and from about 2 to about 6 weight percent of a third component selected from the group consisting of boron, carbon, and combinations thereof.

US Classification:

428613

Abstract:

An extended surface area amorphous metallic article and process for preparation thereof, wherein a homogeneous amorphous metallic alloy is phase-separated to produce two interconnected, internally continuous, amorphous phases, and then one phase is removed. Preferably, the homogeneous metallic alloy has a composition associated with a eutectic between at least two solid solutions. Phase separation is accomplished by exposing the alloy to a temperature which is below the crystallization temperature and also below the phase separation temperature for that composition. Removal of one phase may be accomplished by leaching in a liquid solution, or by vaporization. The resulting article has an extended surface area of the amorphous phase that is not removed. A porous membrane having extended internal surface area may be prepared by continuing the removal process to the removal of one phase throughout the entire thickness of the article. The extended surface area articles, wherein the extended surface area is of an amorphous metal, enjoy particular advantages when used as catalysts.
