Abstract: A method provides for full or partial infusion of resin into three-dimensional, woven textile preforms. Resin film is placed at selected locations adjacent the preform, and the resin film may be separated from other areas of the preform using separator sheets or other materials. The preform is heated and may be vacuum-bagged to apply pressure, or may be rolled or fed through a die. The heat and pressure cause the resin to infuse into the selected areas of the preform adjacent the resin films. The amount of resin in the partial infusion is the same as is necessary to fully infuse the preform, but the resin remains localized in the selected areas until heated again at cure to cause the resin to flow throughout the preform. The method may also be used to fully infuse the preform with resin by providing sufficient temperature and time at that temperature during the initial infusion.

Abstract: There is provided a toilet seat hinge which allows different seats to be quickly replaced or substituted and which will adapt to different manufacturers' bowls. This is accomplished by providing removable hinge pins to secure the seat to the hinge, and adjustable connections from the hinge base to the toilet bowl. The base of the hinge may also be integral with the toilet bowl.

Abstract: Methods and apparatus for providing pre-paid long distance telephone calls without the requirement for dialing an access number or providing a personal identification number. Customers establish accounts with a service provider and keep the accounts replenished with finds. When the customer dials a long distance telephone number, the call is routed to a service provider's IVR platform, where a check is made for sufficient funds in the individual account. If there are sufficient funds, the call is completed, otherwise the customer is routed to a customer service representative and the customer can then replenish his account. The customer can replenish the account using different payment methods, such as at designated locations, the IVR, through the Internet, or with customer service representatives. Payments can be made by providing credit card or other financing information or by sending checks.

Abstract: A floating apparatus for providing breathable pressurized air to a submerged swimmer(s). A inflatable tube supports a combination of two containers at the waters surface. The top container is a sealed battery compartment and mating cover which holds a battery for powering the compressor(s) and a means for mounting said compressor(s) in a position that allows for submersion at the waters surface. The top container is also used as shield and water deflector to prevent the intake of water into the compressors. The outlets of the compressors are joined and adapted to one or more hoses to provide air to a submerged swimmer(s). The bottom container is a cover which protects the electrically powered compressor(s) and provides a means to allow water entry to cool said compressor(s).

Abstract: A toilet seat assembly comprising a first seat, a second smaller seat supported by said first seat when in a lowered position thereof, a cover for the first and second seats, a hinge block and retractable hinge pins for hingedly connecting the first and second seats and the cover to the hinge block.

Abstract: A floating apparatus for providing pressurized air to a submerged swimmer. A floatation device supports a combination of two containers above the surface of the water. The top container, in the form of an inverted box, holds one or more electrically powered compressors. The bottom container holds a battery for powering the compressors. Water ingestion by the compressor(s) is prevented by placing the air intake inside the upper box, which forms an air trap. The air intake and compressors are isolated from any possible contamination or explosion risk from the battery outgassing, which is safely vented to the outside air from the lower compartment. Battery life is extended by pressure switch controls on the air compressor(s), running them on demand instead of continuously.

Abstract: A grooming implement has hand grips and two blades corresponding edges of which have a lengthwise series of teeth. The blades include parallel, spaced-apart grooming portions that remain substantially parallel when the implement is held by the hand grips with the blades curved as one end of one blade is slidable relative to the other blade.

Abstract: Implements for use in grooming animals, scaling fish, and grating vegetables have at least one blade of the band saw type which includes a loop portion and tail portions and a handle of a material that the blade teeth will cut and having a socket. Each socket is dimensioned slidably to receive the tail portions, if held sufficiently close together, but to be frictionally engaged thereby if not so held after their insertion into the socket and to become engaged by the teeth of the tail portions on any relative movement between them and the handle. The loops are of a shape depending on the primary use of the implement. In the case of animal grooming and fish scaling implements there are several loops, one inside another.

Abstract: A cassette contains a pair of endless printing ribbons on separate spools, each ribbon having an independent drive with a mechanism provided to enable shifting from one drive to the other, thereby permitting selection of one or the other ribbon.
