Abstract: A golf club head for a wood club type that has a thick, light weight, low density face wall supported to its rear by a hollow shell structure. The shell structure supports the face wall around the periphery of the face wall, and a club shaft is attached suitably to the rear of the front face of the face wall. The face wall preferably has a club face area greater than 5.3 square inches, and a weight not exceeding half of the total club head weight.

Abstract: Golf club heads are disclosed which have face surface shapes which are designed so as to reduce the scatter of the points where the ball stops after a hit, as compared to face surface shapes of prior art. This is accomplished by use of optimum face surface shapes which respect the USGA requirement for no degree of concavity. The face surface shapes disclosed are different in upward directions from the hit center to the face surface shapes in downward directions.

Abstract: A golf club "wood" of hollow construction includes a shell or wall which is attached to the back side of the face plates and extends rearwardly to a mass mounted as part of the head. The shell or wall is relatively straight in the load bearing direction and is preferably corrugated to suppress buckling failure. The shell or wall may be cast, or if desired thinner sections may be made of sheet material and assembled to support the face by means of welding, silver brazing, or for certain materials, gluing in place. An outer cover may be added to preserve an approximately traditional external shape or to permit other freedom of design of the external shape. The cover is lightweight construction such as fiber-reinforced plastic, or a very rigid foam plastic material.

Abstract: A golf club, specifically a driver, has a roughly elliptical face shape oriented so that the long axis of the ellipse is tilted upward at the toe at an angle of 20 degrees or more. This causes better agreement between the hit pattern and the perimeter of the club face, with the important result of minimizing the percentage of impacts which are not completely on the face of the club. This arrangement is for drivers since no other clubs are normally used with a tee and a consequence is that tilting the ball strike region of the face is not helpful for such clubs.

Abstract: A method for repairing breaks in safety glass, such as that found on automotive windshields, includes as an apparatus a self-contained, small fixture which can be secured to the windshield and centered on the break. The fixture includes connections for applying a vacuum source for evacuating the break, and for connecting a self-contained and self-supported measured quantity of resin to the fixture so that resin will enter the break while the break remains under a vacuum. The introduction of the resin into the break is thus enhanced, because the break is under vacuum. When vacuum is released, pressure may be applied to the resin to force it into the break to completely fill the break and provide for a visually acceptable repair. Curing of resins can then be carried out in a conventional manner.

Abstract: A highly efficient, low cost, heat transfer sheet providing for transfer of heat from the sheet to a fluid and finding particular use in solar collectors.

Abstract: An apparatus for repairing windshields and the method for using the apparatus wherein a liquid, curable resin material is forced into cracks in the windshield, using an apparatus mounted directly to the windshield, and which provides a high injection pressure and subsequently a vacuum so that the crack is completely filled, and air bubbles are removed from the filling resin during the time the resin cures. The apparatus in one form includes a disposable, simple-to-make injector that seals positively around the opening of the crack so that the resin is forced into place, and by reversing the injector, a suitable vacuum can be applied to the injected resin for removal of air bubbles.

Abstract: A fastener for attaching a flexible cover or sheet, such as a canvas tarpaulin, to a structure to provide a cover for the structure, and also to provide an acceptable weather seal around the cover. The device comprises a channel member fixed to the structure to be covered, and used in cooperation with a lock member having a pair of bead portions attached to the cover. The bead portions are separated by a very flexible portion of material so that the outer bead portion will move easily with respect to the inner bead portion. The two bead portions are then inserted into the channel one at a time and once in the channel are held by a detent from releasing under normal tension loads on the cover.
