Abstract: Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.

Abstract: A golf club has a club head forming a generally hollow body having a generally planar front wall for impacting a ball, a rear wall opposite to the front wall, two side walls, a top wall and a bottom wall surrounding a hollow interior. A tubular shaft hosel extends upwardly from the top wall of the club head and an upstanding center wall is located between the side walls and extending rearwardly from the front wall so as to transfer forces between walls. A portion of the hosel is connected to the top wall and the center wall so as to transfer forces therebetween. The front edge of the center wall can be recessed away from the front wall to allow some flexing of the front wall on impact.

Abstract: Tools and methods of making tools that are swung toward a work-piece are more accurate and/or safer to use because of a moveable grip provided on the tool handle. The tool handle slides through the moveable grip, with minimal or no rotation or shifting relative to the grip. The movable grip eliminates the need for the forward hand of the user to loosen its grip during portions or all of the swing, eliminates the need for the hand itself to slide along the surface of the handle, and, importantly, greatly reduces or eliminates the chance that the tool and the impact head of the tool hand will rotate or shift relative to user's hand(s). The moveable grip and handle are preferably rigid and hard and mated in shape and size so that rotation and shifting is reduced or eliminated.
