Abstract: A sports racquet having a plurality of string port holes and conventional string holes is formed of a single tube of prepreg material. When molded, mold elements press opposed portions of the prepreg tube into contact with one another, and shape the adjoining prepreg material into a string port hole blanks. The portion of the pressed-together material which initially blocks the string port hole is removed after molding so that the string port holes extend through the frame. Alternatively, the mold elements cause the prepreg tube to follow a serpentine shape, thereby defining string port holes which are open alternately along the top and bottom surface of the frame. A pair of cover rings may be secured to the top and bottom racquet surfaces to cover the open sides of the string port holes.

Abstract: A method of manufacturing a structure using a single, hollow primary tube, preferably of a composite material, wherein ports are bonded to the walls of the hollow tube through aligned holes on opposite sides of the hollow tube. The ports improve the stiffness, strength, aerodynamics, and aesthetics of the structure.

The cushion member includes a first face, a second face, and a cushion edge portion disposed between them. Both faces have inner portions extending away from the cushion edge portion towards end portions. The inner portions are positioned adjacent surfaces surrounding the edge. The edge attachment includes an upper surface, an attached end, and a distal end. The attached end is attached to one of the end portions of the cushion member. The edge attachment is stiffer than the cushion member. The upper surface of the edge attachment is separated a distance from the surface it is positioned adjacent that tapers from a larger distance at the attached end to a smaller distance at the distal end.

Abstract: A wire mesh burner plate for use in large, gas burners for large ovens is comprised of spaced-apart wire mesh plates. The spacing between the wire mesh plates defines an air/fuel mixture space. The fuel passes through the lower or first mesh, experiences a pressure drop, mixes with air and passes through a second wire mesh. The gas combusts after passing through the second wire mesh. The fine gauge of the mesh prevents combustion from flowing backwardly into the fuel/air mixture space. Several individual wire mesh burner plates can be flexibly attached to each other such that a very wide space can be covered. Thermal stresses are reduced by being distributed across multiple burners.

Abstract: A structure for a bat is described by using multiple composite tubes bonded to one another, wherein apertures, or “ports,” are molded between the tubes to improve the stiffness, strength, aerodynamics and comfort of the bat.

Abstract: A food warming apparatus includes a heating compartment that can hold one or more trays containing previously cooked food portions. A rack in the heating compartment includes a support member, a channel, and a stop that blocks the front end of the channel. A cover that includes a horizontal section and a vertical section is mounted on the support such that the horizontal section is supported on one side by the support member and on the other side by the vertical section, which is positioned in the channel behind the stop. When a tray is inserted into the receiving space defined by the cover and support member, the cover is lifted up so that the horizontal section rests on the tray and at least partially blocks the open top of the tray, thereby restricting evaporation of liquids from the previously cooked food portions contained in the tray.

Abstract: Cooking food in a hybrid conveyor with both electric and gas-fired infrared heaters. The heat output from the gas fired infrared heater is controlled by cycling or pulsing the gas supply to one or more burners that emit infrared heat by heating a nichrome screen wire. The electric power supplied to electrically powered heaters is also controlled.

Abstract: A golf club head has a face, a hosel, and a hollow body. The body includes an outer peripheral region, when viewed from above, and center portions on the upper surface and sole, respectively. The outer peripheral region has a weight-per-unit of surface area which is greater than the weight-per-unit of surface area of the center portions. The weight differential may be accomplished by molding ports into the hollow body around the periphery, which contain weight plugs. Alternately or in addition, a vertically oriented port may extend through the center portions to reduce weight.

Abstract: A toaster for bread-type food products includes a housing defining at least one toasting cavity having an upper mouth for depositing the food products into the cavity and a lower opening from which toasted food products exit the cavity. A perforate rack is provided beneath the lower opening and onto which the toasted food products are deposited as they exit the cavity. The rack is perforated to significantly reduce the surface area of the rack which might otherwise stick to the toasted food products. An imperforate plate is juxtaposed behind the perforate rack to prevent crumbs from the toasted food products from falling into the bottom of the toaster. The plate is spaced from the rack a sufficient distance to prevent any portions of the toasted food products from projecting through the perforate rack and touching the plate and sticking thereto. As disclosed herein, the perforate rack is provided as a wire form structure.

Abstract: The present invention is a technique of, and system for, imaging vascular anatomy over distance considerably greater than the maximum practical field of view of a magnetic resonance imaging system while using substantially one contrast agent injection. The technique and system of the present invention acquires image data of a plurality of image volumes which are representative of different portions of the patient's body. The image data of each image volume includes image data which is representative of the center of k-space. The acquisition of image data which is representative of the center of k-space is correlated with a concentration of contrast agent in the artery(ies) residing in the image volume being substantially greater than the concentration of contrast agent in veins and background tissue adjacent to the artery(ies).
