Abstract: The present invention teaches a residential wall penetrating mailbox with enhanced box handling capability, openable by barcode scanning, and openable from either inside or outside a home. A body which is generally column shaped has front and rear doors which open at the top and hinge near the bottom and which have interleaved fingers or members extending from the bottom ends into the interior space of the mailbox. A box tray sits on the interleaved fingers. When either door is opened the fingers of that door lift the box tray upward and out of the box on that side. Thus, a delivery person may access a box from outside the home, while the homeowner may do the same without leaving the safety of the home interior. In addition, an elastic cord and carefully slanted slots on side panels of the front door allow easy retention of a box even further up the front door.

Abstract: The present invention teaches a residential curbside mailbox with enhanced box handling capability, openable by barcode scanning, and with interchangeable bonnets. A body which is generally column shaped has front and rear doors which open at the top and hinge near the bottom and which have interleaved fingers or members extending from the bottom ends into the interior space of the mailbox. A box tray sits on the interleaved fingers. When either door is opened the fingers of that door lift the box tray upward and out of the box on that side. Thus a delivery person may access a box without leaving a delivery vehicle, while the homeowner may do the same without leaving the safety of the yard. In addition, an elastic cord and carefully slanted slots on side panels of the front door allow easy retention of a box even further up the front door.

Abstract: A method for producing a gasket insert comprising: providing a strip of insert material having a predetermined thickness; providing a pair of rigid parallel surfaces spaced apart by a distance approximately equal to, but greater than, the thickness of the insert material; placing the insert material between the surfaces; and bending the insert material to a desired shape. Also disclosed is a method for producing a gasket comprising: providing a strip of insert material having a predetermined thickness; providing a pair of rigid parallel surfaces spaced apart by a distance approximately equal to, but greater than, thickness of the insert material; placing the insert material between the surfaces; bending the insert material to a desired shape; and molding an elastomeric material to the insert.

Abstract: An annular seal and method of producing the same wherein the annular seal comprises an annular outer portion comprising an outward facing surface and an inward facing surface; an annular rubber portion having an outer face and an inner face, wherein the outer face of the annular rubber portion is bonded to the inward facing surface of the annular outer portion; and wherein the inner face of the rubber portion comprises a plurality of bulged areas. Preferably, the outer portion comprises polytetrafluoroethylene or perfluoroalkoxy. The bulged areas may be disposed radially inwardly or axially.

Abstract: A piston seal comprising a piston seal insert having a top side, a bottom side, an outer substantially circular periphery and a central opening defined by an inner substantially circular periphery; an elastomer molded without adhesive over at least the inner periphery or the outer periphery; and wherein the molded elastomer comprises a lip portion extending upwardly and radially away from the piston seal insert.

Abstract: An annular seal and method of producing the same wherein the annular seal comprises an annular outer portion comprising an outward facing surface and an inward facing surface; an annular rubber portion having an outer face and an inner face, wherein the outer face of the annular rubber portion is bonded to the inward facing surface of the annular outer portion; and wherein the inner face of the rubber portion comprises a plurality of bulged areas.

Abstract: A ball valve comprising a seat having a first opening thereon, a housing over the seat having a second opening defined by a flap having an inner and outer diameter, and a ball in the housing, the ball having a diameter great than the inner diameter of the flap. The seat may be formed directly onto a metal insert of a bonded piston seal, or directly onto a wall of any chamber needing a ball valve therein. The housing may be formed as an extension of a piece of rubber used to seal the periphery of the insert or chamber wall. Hence, the housing and insert or chamber wall may be molded together as part of a unitarily formed chamber and ball valve combination.

Abstract: An apparatus for incinerating the metal shaft of hypodermic needles which includes a housing having adjustable electrodes mounted therein which when supplied with electric current and contacted with a metal shaft of a needle will instantly disintegrate the needle to a safe residue which is collected in a tray within the housing. Gases generated within the housing from the incineration process are purified by passing through filters and ionizers before being vented to atmosphere.

Abstract: A rotatable and removable bed tray for institutional or private home use. The bed tray is easily adjustable by the bedridden patient or by others. Further, there is provided bed rail adaptor for adopting beds without bed rails to use the bed tray.
