Abstract: A generally hollow removable tooth cap defines a cavity for receiving a real tooth as well as material for removably attaching the tooth cap to the real tooth. The tooth cap has a front side and a back side which terminate together at the distal or free end of the tooth cap. The back side of the tooth cap further defines a recessed area which extends longitudinally along the backside from an area adjacent the distal end of the tooth cap until it opens into the cavity of the tooth cap. The tooth cap is also provided with a nonlinear passageway in the bottom of the tooth cap's cavity for receiving the attaching material to secure the material to the tooth cap.

Abstract: A removable tooth cap defines a cavity for receiving a real tooth as well as material for removably attaching the tooth cap to the real tooth. The tooth cap has a front side and a back side which form a tip at the distal or free end of the tooth cap. The back side has a length which is less than ? of the overall length of said tooth cap. The back side further defines a hole for receiving the material so that said material anchors or locks to the tooth cap when the material hardens.

Abstract: An artificial and removable tooth cap body and a method of easily attaching the tooth cap body to a real tooth. The tooth cap body is anchored to the real tooth with a low melting point and malleable thermoplastic material. The tooth cap body includes ridges and/or depressions so that the thermoplastic material can anchor and attach to the tooth cap body.

Abstract: A cardboard coffin is constructed from a blank cut from a sheet of corrugated cardboard having a predetermined width wherein the blank has a central body portion, a longitudinal axis and a perimeter defined by linear score lines having integral generally rectangularly shaped portions extending therefrom and each of which is provided with a pair of spaced apart score lines for defining an edge portion when folded about the spaced apart score lines. The linear score lines defining the central body portion include a pair of relatively short linear score lines and a pair of relatively long linear score lines which are inclined at different angular relationships to the longitudinal axis and both pairs having segments of their edge portions in parallel relationship so that the central body portion can have a greatest width in relation to the predetermined width of the sheet from which it is cut.

Abstract: A cardboard coffin for use at parties or similar occasions which is formed from a plurality of corrugated cardboard blanks having appropriate score lines formed therein to facilitate folding comprising a bottom having a central body portion having a perimeter in the shape of a coffin and defined by a plurality of score lines. A plurality of integral rectangularly shaped portions extend upwardly from the perimeter and have an angular relationship with the central body portions of about 90 degrees wall portions are formed from two cardboard blanks having score lines so that the two cardboard blanks may be folded along the score lines to form two opposite side wall portions and overlapping top and bottom wall portions which are secured together by tape. The integral rectangularly shaped portions of the bottom are secured to the adjacent surfaces of the wall portions by tape.

Abstract: An electronic system is disclosed that is particularly useful for synchronizing motion picture and sound recordings. The system includes a sensor that is positioned contiguous to a movie camera during filming and contiguous to a movie projector during film playback to sense a characteristic indicative of film movement and, responsive thereto, producing an electrical output signal. During filming, a sensor, such as a microphone or induction coil, may be positioned contiguous to the movie camera such as by placing the sensor in a cylinder screwed into a camera tripod socket. During playback, the sensor, such as a light sensor, may be positioned to sense light bursts of a running movie projector. A control unit receives the electrical output signal from the sensor and utilizes the same in controlling operation of an associated tape recorder.
