Abstract: An improved readily attachable and detachable coupling for fluid conduits including a receptacle member having a passageway therethrough and having at least one notch formed in the external surface communicating with the passageway, the notch having a forward wall inclined at an acute angle to the member longitudinal axis and a rearward wall which is substantially perpendicular to the longitudinal axis, and a plug member of a diameter to be slideably received within the receptacle member passageway, the plug member having an enlarged external diameter portion spaced from the end, the receptacle member having a retention wire received thereon with a straight portion extending within the notch and with the wire extending less than the full circumference of the receptacle, the ends of the wire being spaced apart so that when the plug member is inserted into the receptacle passageway, the enlarged diameter portion can push past the retention wire, and a release collar received on receptacle and having a portion w

Abstract: An improved self-adjusting mechanism for a cable-operated vehicle brake is disclosed. The operating lever is pivoted about an axis on a frame member which carries a fixed sector. The lever carries a first pawl, which is adapted to releasably hold the operating lever in position with respect to the frame, and a second pawl which locks the lever to a sheave sector fixed to a sheave which winds up the brake cable upon pivoting of the lever. A third sliding pawl is mounted on the sheave sector. When the operating lever is rotated beyond a predetermined degree in setting the brake, the sliding pawl abuts a stop on the frame. This moves the sliding pawl with respect to the sheave sector. When the handle is subsequently returned to its rest position, the sliding pawl allows a limited amount of rotation of the sheave sector with respect to the lever, which occurs due to tension exerted on the brake cable by the brake shoe return spring.

Abstract: A readily attachable and detachable coupling for fluid conduits including a receptacle member having a passageway therethrough and having a notch formed in the external surface communicating with the passageway, the notch having a forward wall inclined at an acute angle to the member longitudinal axis and a rearward wall which is substantially perpendicular to the longitudinal axis, and a plug member of a diameter to be slideably received within the receptacle member passageway, the plug member having an enlarged external diameter portion spaced from the end, the receptacle member having a retention wire received therearound and extending within the notch and gaskets within the passageway so that when the plug member is inserted into the receptacle passageway, the enlarged diameter portion can push past the retention wire because the retention wire can expand against the inclined planar wall of the notch but after having passed is prohibited from being withdrawn from the receptacle member by the retention wir

Abstract: A composite fuel and vapor tube having increased heat resistance with a composite wall having a relatively thin nylon liner, a metal strip about the liner and having a longitudinal seam, the tube being encased within a polyethylene jacket. The line thus formed has increased resistance to heat, abrasion and various fuels, is bendable and is capable of maintaining its shape after bending or forming operations.

Abstract: A conduit harness connector assembly comprising: an elastomeric female member having a body portion with first and second opposite sides and at least one integrally formed flexible, stretchable tube extending from one side thereof and bore extending through the tube and through to the second side of the body, each tube having a predetermined internal diameter; a first set of conduits wherein a separate conduit of the set extends into each of the flexible tubes, each of the conduits having an outer diameter greater than the inside diameter of the tubes, which are stretched over them to provide an elastomeric fit; a comparatively rigid male member having first and second opposite sides wherein a tube extends from one side thereof for each bore in the body portion of the female member and for insertion thereinto from the second side of the body portion and means for separately connecting a second set of individual conduits in fluid communication with each of the tubes thereof.

Abstract: Copper-zinc-manganese-nickel alloys comprising 30 to 70 weight percent copper, 15 to 45 weight percent zinc, 5 to 20 weight percent manganese, 1 to 20 weight percent nickel, 0.05 to 2 weight percent silicon and less than about 0.05 weight percent of other elements. Also, use of this alloy as a brazing material and a method for brazing carbide compounds to a suitable substrate utilizing such brazing materials.

Abstract: A copper based alloy consisting essentially of about 4-15 wt. percent nickel, about 4-8 wt. percent tin, the balance essentially copper, to which was added to said copper, nickel and tin, prior to casting, about 0.002-0.4 wt. percent of rhenium. Improved grain structure in the as-cast metal, as well as a retained finer grain structure through homogenization anneals is realized. Finer grain structure after standard processing with attendant improved cold working characteristics, and improved strength for strip material made by standard processing procedures is also obtained. The invention is further directed to the method of producing the alloy.

Abstract: An electrolyte for depositing gold on a surface includes an alkali gold cyanide, a weak Lewis acid, a weak polyfunctional water-soluble aliphatic acid, a non-depositing metallic compound, a metallic hardener, and water.
