US Patent:

44087608, Oct 11, 1983

Filed:

Nov 9, 1981

Appl. No.:

6/319576

Inventors:

Harry Ferrari - Pittsburgh PA

International Classification:

A63B 4900

US Classification:

273 73D

Abstract:

A racquet in which the area of the string which manifests relatively true rebound of the ball, the so-called "sweet spot", is maximized. To achieve this condition the strings are so tensioned or so structured that the deflection produced by impact of the ball near the outer periphery of the racquet is substantially equal to the deflection near the center of the racquet. The strings are subjected to lower tension near the outer periphery than near the center of the racquet or they are of smaller thickness near the outer periphery than near the center or they are differently irradiated. So as to achieve the different tensions with strings of a given diameter, a plurality of separate short string lengths are used.

International Classification:

A63B 4902

US Classification:

273 73C

Abstract:

A sports racket has a handle and a multi-frame. The multi-frame includes a primary frame defining a throat connected to the handle and a hoop-shaped head connected to the throat and encompassing an open region. The head has a plurality of stringing holes defined therethrough for attaching stringing to the head and across the open region. The multi-frame also includes supplementary frames and ribs. The supplementary frames are disposed in spaced relation and adjacent to opposite sides of the primary frame. The supplementary frames are coextensive with all or a portion of the primary frame head, plus all or a portion of the primary frame throat. The ribs are spaced from one another and extend between and rigidly interconnect the supplementary frames with coextensive portions of the primary frame. The ribs and supplementary frames serve to increase the stiffness of the primary frame, reducing axial and torsional deflections thereof upon striking a ball by the stringing across the open region of the head. The multi-frame further includes supplementary bracing interconnecting portions of the supplementary frames alone or with the primary frame in the region of the throat thereof.

Appl. No.:

6/552227

Inventors:

Harry M. Ferrari - Pittsburgh PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G21C 300

US Classification:

376417

Abstract:

A nuclear reactor component such as a fuel rod, burnable absorber rod, or neutron absorber rod, comprising a hermetically sealed metallic tube containing a solid material such as a nuclear fuel, burnable absorber, or neutron absorber, within a helium atmosphere, which solid material will release tritium into the helium atmosphere, has added thereto about 2-3 percent by volume of a gas, selected from oxygen, carbon monoxide and carbon dioxide. The addition of this gas to the helium atmosphere is effective to form an oxide layer on the inner surface of the metallic tube and significantly reduce the permeation of tritium through the metallic tube, such that the tritium is retained within the reactor component.

Appl. No.:

7/740342

Inventors:

Harry M. Ferrari - Fox Chapel PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G21C 726

US Classification:

376209

Abstract:

A spectral shift-producing subassembly is composed of a plurality of sealed empty water displacement rodlets incorporating a spectral shift-producing capability. Each of the rodlets includes an elongated tube sealed at its opposite ends and having an axially-extending annular wall section of reduced thickness compared to the thickness of the wall of the remainder of the rodlet. The respective reduced thicknesses of the axial wall sections of the rodlets can be varied to adapt the rodlets to rupture at different times and permit water to enter the rodlets to produce an increase in the water/fuel ratio and thereby an increase in reactivity. The rodlets can also have different levels of pressurization to initiate rupture at different times.

International Classification:

A63B 4906

US Classification:

273 73C

Abstract:

A racket frame, such as for a tennis racket, has a head portion, a handle portion and a throat portion extending between and interconnecting the head and handle portions. The head portion encompasses an open region and has a first plurality of stringing holes for attaching stringing to the head portion and across the open region. The throat portion is in the form of a pair of legs in a generally V-shaped configuration. The frame also includes a second plurality of non-stringing holes defined in one or both of the head and throat portions for forming voids in the material thereof to reduce the weight and tailor the stiffness thereof in a manner which reduces axial and torsional deflections of the head portion upon striking a ball by the stringing across the open region of the head portion.

US Classification:

376439

Abstract:

A nuclear fuel assembly having an array of longitudinally extending fuel rods and axially spaced transverse grids with cells receiving the fuel rods therethrough employs anti-fretting protective devices for protecting lower end portions of tubular claddings of the fuel rods from damage-inducing contact with debris entrained in upward flow of coolant through the fuel assembly. Each device is in the form of a hollow sleeve disposed about and extending coextensive with the lower end portion of one fuel rod cladding. The sleeve has an upper portion which extends through one grid cell between lower and upper ends thereof, and a lower portion which extends below the grid cell from the lower end thereof to a bottom end of the fuel rod cladding spaced below the grid cell lower end.

US Classification:

250492R

Abstract:

String of polyamide is irradiated with dosages of 10. sup. 4 to 10. sup. 10 rads. It has been discovered by actual experience that in string which is treated in this way the cross linkage of the molecules is enhanced. Such string has higher elasticity and substantially lower damping when set into oscillation than untreated string and that a tennis racket produced with such string is superior to a racket with untreated polyamide string. The dosage is not so high as to cause the string to become brittle.
