Abstract: A method and device for preventing a golfer's hands from slipping off a golf club grip. The device has a body with an opening that defines an inner perimeter of the body, an outer perimeter spaced radially outward from and surrounding the inner perimeter, and a slot in the body that extends between the inner and outer perimeters thereof. The slot has a width greater than the diameter of the golf club shaft to permit installation of the body on the golf club. The opening in the body has a minimum dimension larger than the diameter of a second grip portion of the grip but smaller than the diameter of a first grip portion of the grip, so that the body can be prevented from being removed from the club over the first grip portion. In this manner, the device is secured on the grip by an interference fit.

Abstract: An improved modular heat exchanger suitable for automotive applications, and particularly radiators for heavy duty equipment, and methods for forming the modular heat exchanger. The modular heat exchanger construction incorporates a brazed core assembly composed of flat-type cooling tubes and sinusoidal centers. The ability to use a brazed core assembly within a modular heat exchanger construction promotes enhanced heat transfer efficiencies associated with the use of flat tubes and sinusoidal centers, as compared to mechanically-joined round tubes and fins. The required positional tolerances of the tubes for mating with the remainder of the heat exchanger are maintained within the brazed core assembly by eliminating core shrinkage attributable to the use of clad aluminum alloy components to construct the core assembly. In two embodiments, core shrinkage is physical suppressed through the use of an expandable brazing fixture or the inclusion of sub-headers in the brazed core assembly.

A first member has a slot in a surface thereof, while the second member has an edge received in the slot of the first member. One or both of the first and second members has one or more features that force the edge of the second member away from the first surface of the slot and into contact with the second surface of the slot during insertion of the edge into the slot. An adhesive within the slot bonds the second member to the first member.

Abstract: A system and method for supplying thrust to a structure, such as a satellite or spacecraft, for the purposes of station keeping and attitude control of the structure in low-gravity (orbital) and zero-gravity environments. The system includes devices for emitting energy beams and targets impacted by the energy beams to cause ablation of the targets. The beam-emitting devices and targets are adapted to cooperate and cause the structure to selectively undergo translational and/or rotational motion in reaction to the motion of material ablated from the targets. The position, alignment, and/or attitude of the structure can thereby be controlled in a zero or low-gravity environment by selectively emitting the energy beams at the targets.

Abstract: A process by which the end of a tube having at least one internal surface feature is reduced and at least a portion of the surface feature eliminated from the tube end while achieving accurate control of the outer diameter of the tube end. The process preferably makes use of a forming tool comprising an external die for reducing the outer diameter of a tube and a mandrel for deforming the internal passage of the tube. The process generally comprises forcing the external die over the end of the tube so that the outer diameter of the tube end is reduced and so that the mandrel is simultaneously inserted through the internal passage of the tube end. While the tube end remains within the external die, the mandrel is withdrawn from the internal passage of the tube end to eliminate the internal surface feature.

Abstract: A method and device for assessing the viscosity of a fluid.
