Abstract: A unique vacuum cleaner attachment specifically configured for dust removal from the interior of any 31/2 inch (88.9 mm) disk drive unit, commonly found in conjunction with electronic computer and word processor equipment. The attachment comprises a vacuum cleaner hose fitting at one end running parallel to a hollow body member which allows for grasp along its length and terminates at opposite end after gradually being reduced in diameter and increased in width from the grasp portion so as to provide a hollowed disk for insertion. On the exterior of the attachment's top and bottom sides, which are symmetrical and thus reversable, find positive stops located at the points where the diskette shaped configuration begins and centered along that plane.

Abstract: The invention relates to a method and apparatus for brazing two metal members together, at least one of which is nonplanar, in a brazing furnace using a substantially pure brazing material. The method comprises the steps of utilizing a brazing fixture to hold the two metal members in tangential relation to one another along a portion of each member so that a cavity is formed adjacent to the contacting portions. A braze material is then positioned within the cavity. The braze fixture, the metal members, and the braze material are then placed in a brazing furnace. A heat shield is then placed over the braze fixture, the metal members, and the braze material to shield the braze material from direct furnace radiation. The furnace temperature is linearly increased at a rate of about 180.degree. C. per hour until a temperature of 350.degree. C. is achieved. Heat is transferred by conduction from the metal members to the braze material to cause the braze material to melt.
