摘要： A heat extracting substrate is moved along a melt front formed at the edge of the surface of a molten material so that a layer of molten material is deposited on the substrate, cooled and removed from the substrate to form ribbon, filaments, fiber or film directly from the molten material. The edge may be formed by providing an upper edge upon a portion of the wall of a receptacle lower than the top of the receptacle. The molten material may be overflowed over this relatively horizontal edge and against the moving substrate surface.

摘要： A stepped golf club shaft with cylindrical segments joined by conical bands. The shaft is a composite with longitudinal and helical reinforcing fibers. The majority of the longitudinal fibers are located within the inner half of the shaft sidewall thickness, and the helical fibers are located within the outer half. A cutting tool is inserted into the bore of the hollow shaft and severs some of the longitudinal fibers to reduce the shaft stiffness, and therefore the natural frequency of oscillation, of the shaft.

摘要： The flow control of molten alloy material in a tundish is improved by the design of a perpendicular turn in the path of flow of the molten alloy material as the flow leaves an intermediate section of the tundish or casting receptacle and overflows transversely an exit lip to thereby contact a heat-extracting substrate. The perpendicular turn in the flow achieves improved control of the molten alloy material's velocity profile, cooling rate, and depth and flow uniformity of the molten alloy material in the casting receptacle. The essentially perpendicular turn in the path of the molten alloy material from the intermediate section causes the molten alloy material to approach the exit lip in a transverse direction unlike conventional laminar or direct delivery molten flow. The transverse flow relative to the direction of the exit over-flow toward the casting or cooling surface facilitates improved mixing of the molten alloy material, improved control of the depth gradient, and improved control of the velocity into the exit lip.

摘要： A preform useful in forming fiber reinforced cementitious composites is disclosed. The preform consists of a free-standing network of metal fibers. In one embodiment, the preform has a shape which bounds a substantial non-interstitial volume devoid of fibers such as a ladle lip ring or an I-beam. The amount of fibers in the preform ranges from about 1 to 10 percent by volume.

摘要： A method for measuring the swing time of a golfer's swing and selecting a golf club having the inverse of four times its natural frequency which is approximately equal to the swing time. The golfer's swing time is defined as the time elapsed between maximum acceleration of a club head during downswing until ball impact. In the preferred embodiment, an accelerometer is mounted within the club head and is connected to an electronic data processor. A graph of club head acceleration versus time is plotted and the swing time is measured from the graph, between peak acceleration and ball impact.

摘要： The club length and club frequency attributes of each of a plurality of golf clubs in inventory are obtained and the data are arranged in a two dimensional array. The golfer's swing frequency for a test club of a particular test club length is measured. An inventory club is selected, from the inventory array having substantially the same length as the test club and having the closest frequency to the golfer's swing frequency of any inventory club in that array of that length.This process can be employed for one or more clubs. Alternatively, only a few club lengths can be tested to obtain swing frequencies for those clubs. The swing frequencies of any intermediate, untested club lengths are interpolated by standard numerical analysis or obtained by plotting the data points and connecting them with a curve.

The tipping amount is calculated from the equationtipping amount=(f.sub.g -C-B*m.sub.g).div.Awhere m.sub.g is the desired moment and f.sub.g is the desired natural frequency of a golfer's finished golf club. A length of the narrow end of the inventory shaft equal to the tipping amount is removed and a length of the grip end of the inventory shaft may also be removed if necessary.
