A novelty drinking container device with a disappearing object, such as a photograph such that a drinking cup is separated into top and bottom portions by a convex magnifying lens, with the lens pointed in its apex direction upward toward the mouth of the cup, and the lens is situated above an air space to permit the refraction and distortion of light rays when the cup is empty, and permitting the display of a novelty object, such as a photograph housed in a round-shaped compartment at the base ...

A simulated burner for a toy cooking stove, range or the like. The burner comprises a first member having at least one slot extending therethrough. The burner has a second member having a projection complementary to and in register with the slot. The first and second members are preferably of contrasting colors. The first and second members are movable relative to one another causing the projection to gradually move between retracted and extended positions. In the retracted position, the project...

The cabin houses display means producing a window-type display, display storage devices to play a real-life panorama or other picture, remote microprocessors to control display storage devices and to produce computer generated pictures on said display means, a CPU to control the cabin movement, to synchronize the display change with the movement of the cabin and to co...

A simulated car phone includes a handset unit configured to resemble an operational car phone. The handset unit includes a simulated keypad and a simulated signal cord. A radio frequency receiver is provided in the handset for receiving signals from a small remote battery powered unit radio frequency transmitter. A battery powered audio tape player in the handset unit produces simulated telephone ring signals through an audio speaker. The audio tape player is actuated by switching circuitry in t...

The present invention refers to a magic card formed of blanks and provided with a cover and with a slide member, which is guided in said cover and which is adapted to be pulled out of said cover at least partially, said cover having a front wall and a rear wall as well as an insertion opening on one side thereof and said slide member having two slide member surfaces, which are placed one on top of the other and which are interconnected on one side thereof, one of said slide member surfaces being...

A dental floss woven in a chinese finger cuff pattern is provided. The dental floss is woven with a sufficient number of fibers to be self-supporting. The chinese finger cuff weave allows for constriction of the dental floss about its longitudinal axis when tension is applied in the longitudinal direction. The hollow cylinder defined by the chinese finger cuff weave may be filled with fluoride or other cleaning substances such that when the dental floss has longitudinal tension applied to it the...

A trenching casing for the continuous excavation and refilling of trenches for the installation of conduits into the ground has spaced side walls consisting of at least upper and lower sections which are longitudinally movably relative to each other and each of which has a rear face plate with a hydraulic advancing cylinder for pushing the respective section forwardly, and the upper and lower sections are interconnected by hydraulic operating cylinders which facilitate the advancing of one of th...

An automated sheet-feed apparatus for feeding cut sheet paper to an automated printer includes apparatus for forming a predetermined length of buckle in the sheet of paper. The sheet-feed apparatus feeds the leading edge of a sheet of paper into a nip formed by the platen and the first set of pressure feed rollers of the printer. As feeding of the sheet of paper continues, a predetermined length of buckle is formed in the buckle chamber, at which time feeding by the sheet-feed apparatus is stopp...

A ditch-digging or trenching machine has a plurality of wall-engaging spreadable and retractable members which can be received in the trench to be advanced and provided with respective fluid-powered cylinders connectible to a cutting head for advancing the latter and drawing the retracted wall-engaging members thereafter to cut the trench. The cutter head includes a milling-type cutter in the form of a worm conveyor adapted to convey the detritus from the trench.

An illusion creating device comprises a support structure having a support edge encircling an aperture and a flat element. An elastic membrane is supported on the support edge and is stretched over the flat element to a degree wherein a supporting segment of the membrane underlies a portion of the element and supports it. The flat element is viewable through the membrane so as to appear to be disposed on top of the membrane. Pressing the stretched membrane over the flat element causes the elemen...
