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.

Abstract: An improved hydroformylation process involving reacting one or more reactants, such as an olefin, with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst, to produce a reaction product fluid comprising one or more products, preferably aldehydes; wherein said process is conducted in a region of the hydroformylation rate curve that is negative or inverse order in carbon monoxide, which is sufficient to prevent and/or lessen deactivation of the hydroformylation catalyst; and wherein total pressure is controlled at a predetermined target value and/or vent flow rate is controlled at a predetermined target value, by adjusting a flow of a carbon-monoxide containing inlet gas, so as to prevent and/or lessen cycling of process parameters, e.g., reaction rate, total pressure, vent flow rate, and/or temperature.

Abstract: A hydrocarbonylation process for producing an aldehyde or a mixture of a ketone and an aldehyde which comprises:(I) forming a reaction mixture comprising:(a) a catalytic amount of a complex catalyst consisting essentially of rhodium in complex combination with:(i) a triorganophosphine, and(ii) a carboxylic acid having a phenyl group substituted at the para position with a non-reactive electron-withdrawing group, said phenyl group being free of further substitution and said electron withdrawing group being substantially non-reactive in said process;(b) an alpha-olefin having 2 to 5 carbon atoms,(c) carbon monixide, and(d) hydrogenwith the proviso that the reaction mixture has mole ratio of said carbxoylic acid to rhodium of at least about 2; and(II) maintaining the reaction mixture at a temperature and pressure at which said (b), (c) and (d) react to form an aldehyde or a mixture of an aldehyde and a ketone.

Abstract: A method for recovering a transition metal, e.g., rhodium, from a non-polar organic solution containing non-polar organic solvent-soluble and polar solvent-insoluble coordination complex of the transition metal and a non-polar organic solvent-soluble and polar solvent-insoluble ligand, e.g., an organophosphorus ligand, by contacting the non-polar organic solution with a polar solution of an ionic organophosphine ligand, the transition metal then can be transferred back into a non-polar solution for reuse. In one embodiment rhodium is rendered amenable for back-extraction by treating the polar solution with a suitable conditioning reagent.
