Abstract: A drug injection device consists of a body, a cap, a striker, a spin wheel, a button, a spring, an ampoule, and optionally a needle. Each of the body, the cap, the striker, the spin wheel and the button is a molded plastic part, made out of mostly polycarbonate, which slide, snap, screw or rest in place, without the use of adhesives or fasteners. Also disclosed is a system for recycling a drug injection device having molded plastic parts made from mostly polycarbonates, comprising disassembling the drug injection device, separating the molded plastic parts from all other parts, and reprocessing the molded plastic parts together into recycled resin, which may be through regrinding, melting, and pelletizing.

Abstract: The present invention provides high security polycarbonate laminates integrated with insulated glazing units (IGU) to produce high security windows. The laminate comprises at least nine layers, in the following order: (i) an insulated glazing unit; (ii) a thermoplastic polyurethane; (iii) a polycarbonate; (iv) a thermoplastic polyurethane; (v) a polycarbonate; (vi) a thermoplastic polyurethane; (vii) a glass; (viii) a thermoplastic polyurethane; and (ix) a polycarbonate. A frame may surround and overbite the laminate. An array of framed laminates may be arranged such that one framed laminate may be removed, without removing an adjacent laminate.

Abstract: The present invention provides a lightweight blast-mitigating polycarbonate laminate system comprising at least one polycarbonate sheet, a portion of which is laminated to a glass layer having a thickness between 0.25 times and less than 1 times the thickness of the polycarbonate sheet. The laminate system may further include fasteners to attach the system to a building, positioned to prevent the laminate system from breaking or detaching in case of a blast event.

Abstract: A toilet bowl cleaning tool comprising a hollow curved elongated outer member with a handle at the proximal end and a head at the distal end, an inner member and a disposable swab that attaches to the head. The inner member moves linearly inside the outer member, controlled by a button that protrudes through a longitudinal slot in the top of the outer member. Movement of the button affixes the disposable swab to and releases it from the head by actuating radially outwardly projecting detents which are radially expandable and retractable. When the swab is attached to the head, the detents positively engage a receptacle in the swab by gripping the end of the receptacle distant from the handle. The cleaning swab comprises multiple cleaning surfaces of loops of strips of biodegradable sheet material surrounding a biodegradable receptacle and is infused or impregnated with cleaning and disinfecting chemicals.

Abstract: A utensil for containing electric power cords and other cords for electrical devices is a one-piece tube having a uniform wall thickness. One or both ends of the tube are flared so as to receive a cord which has been folded into a bundle. The central, non-flared portion of the tube firmly grips the bundle. Preferably the utensil is made of plastic and has a polygonal cross-section.
