  • Publication number: 20240123307
    Abstract: A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

  • Patent number: 4048058
    Abstract: There are disclosed a method for sulfiding a multi-metallic catalyst or a bi-metallic catalyst and a method for initiating the reforming of a petroleum hydrocarbon feedstock in a reforming reaction zone containing a multi-metallic catalyst or a bi-metallic catalyst.The method for sulfiding is employed when a hydrogen-rich gas containing light hydrocarbons is used in the sulfiding of the catalyst. The method comprises passing a stream of said gas over said catalyst at a temperature of about 350.degree. F. to about 470.degree. F., injecting a sulfur-containing compound into the stream of gas up-stream from said catalyst in order to provide a sulfur-carrying gas, and contacting said catalyst with said sulfur-carrying gas at said temperature for a time that is sufficient to provide a sulfur concentration on said catalyst of about 0.1 to about 2.5 moles of sulfur per mole of total active metal. A typical sulfur-containing compound is dimethyl sulfide.
