Abstract: A protective bib-garment system is described wherein a bib is detachable from the garment it protects, but can not rotate around the wearer's neckline. It thereby provides better protection and safety for the user. The bibs are easily attached or removed for separate cleaning when soiled. The danger of the user choking by having the bib rotate and tighten around the neck is generally removed. Better protection of the underlying garment is also achieved by keeping the bib anchored in front of the user. The system includes bib-ready garments in a wide range of styles, substantially any garment that could be worn by a bib user and is modified to accept the bib portion. These garments can be worn without the bibs and undergarments are protected from outside view or contact by the overlapping garment-bib interface attached to the inside surface of the garment.

Abstract: A bib suitable to be worn by a child during feeding. The bib includes a main body covering at least a portion of the child's chest and stomach. A front side of the main body faces away from the child and includes a representation of a decorative character. One or more components of the decorative character are affixed to the front side of the main body. The bib further includes an extension extending outwardly from a peripheral edge of the main body. The extension is a component of the decorative character. The extension includes a front side facing away from the child and a back side facing toward the child. The front side is fabricated of a soft, absorbent material suitable for wiping the child's face and the back side is fabricated of a stiffer material providing rigidity to the extension such that the extension has sufficient resiliency to return to an outwardly extending position with respect to the bib main body after the extension is used to wipe the child's face.

Abstract: Garments that utilize complex panel shapes to minimize the to number of panels used, the number of seams, and total seam length. Increasing the complexity of panel shapes tends to make the cutting of panels more difficult and often results in more wastage of material, but the reduction of the number of panels and reduction in the number of seams and total seam length will actually simplify garment production and result in improved garments. Simplifying garment production will in turn generally result in an increase in the rate of production. Reducing seam length and the number of seams also reduces the chances of seams wearing out or splitting.

Abstract: An outerwear garment comprises a body of water repellent material, a neck formed in the garment, and a hood secured to the neck. An opening is formed at the front of the hood so that the face of the wearer is exposed, and a resilient drawstring pulls the perimeter of the opening against the fact of the wearer. A brim projects forwardly from the hood at the upper end of the opening to protect the face of the wearer of the garment. A pocket is formed in the interior of the brim. The bill of a conventional athletic cap is inserted into the pocket when the cap is worn. Manual adjustment devices, at the rear of the hood, allow the wearer to draw the hood tightly about the head of the wearer. Resilient inserts may be secured between the hood and the neck of the garment. The hood and cap move in unison, without slipping and impairing one's field of vision when the wearer rotates or pivots his head.

Thus old, handicapped or sick persons or persons who have no firm stand or are being rehabilitated are enabled to use a toilet with protection against splashing of urine.

Abstract: FlowSentry is an apparatus designed to save water in a conventional operating toilet. When the level of water in a toilet tank drops ? of an inch (absent a normal flush) FlowSentry alerts the user of the toilet, by way of an audible alarm, that the toilet is leaking water. FlowSentry only determines that the level of water in the tank has dropped or risen (in an overflow situation), it cannot diagnose the cause of the drop or rise in water level (i.e. leaking flapper, faulty overflow tube, etc.). During the normal flush process the Flow Sentry monitors the time it takes the tank to refill with water and determines if the supply valve has closed properly. If the water level fails to return to normal level in one minute or tank continues to fill exceeding normal level, a continuos audible alarm will sound until corrective action is taken or the 9V battery is exhausted.

Abstract: A portable toilet chemical additive charging system comprises a restroom cabana containing a toilet bowl which opens into a waste-holding tank. A water source, such as a separate water tank, is connected by a conduit to the toilet bowl for delivering flush water to the bowl when a flush pump, that is connected to the conduit, is actuated. The flush water passes through a control valve in the conduit. A chemical additive container is removably positioned near the toilet bowl and is connected by a tube to the control valve. The control valve injects a pre-determined amount of additive to the flush water when flush water is flowed through the control valve to the bowl. Preferably, the container is shaped to closely fit within a space between a vent pipe extending upwardly from the waste-holding tank and the adjacent interior surface of a wall of the cabana.

Abstract: Pool covers embodying the invention are formed of a very dense mesh material which ensures substantially one hundred percent shade while allowing water to pass uniformly through the cover and which is adequately strong to support the weight of an adult. The pool cover is formed of plastic fibers which are interwoven to form a dense mesh which is then subjected to a pressure and heat cycle to ensure that the resultant material has the requisite properties for allowing water to pass through at a desired rate (e.g., 0.1 to 5 gallons per square foot per minute) while blocking light (e.g., 100% shade). Thus, a self-filtering safety pool cover is formed which allows for water to pass through uniformly across its surface while blocking sunlight.
