Abstract: A coin mechanism is provided with a magnetic system for preventing rotation of a coin mechanism intended for use with a magnetic coin when a non-magnetic coin or token is deposited into the mechanism, and for preventing rotation of a coin mechanism intended for use with a non-magnetic coin when a magnetic coin or token is deposited into the mechanism. A magnet is lodged in the arm of a rocker which is biased away from the coin recess in the coin conveyor. The attractive force of the magnet on a magnetic coin or token inserted into the coin recess overcomes the force biasing the rocker arm, causing the rocker arm to move toward the coin or token.

Abstract: A system and method for recycling a waste glass cullet includes a first screening station for separating large glass shards of approximately one inch in diameter from smaller glass shards in the cullet, a crusher to reduce the large glass shards to smaller glass shards smaller than approximately one inch in diameter, a second screening station to separate remaining large contaminants having a diameter of approximately one inch or greater from the cullet, a series of vacuum inlets disposed along a conveyor to remove light contaminants, a presoaking apparatus comprising a holding tank partly filled with a presoaking solution, a rotary washing apparatus comprising a drum with vanes disposed along an inner wall of the drum to toss the cullet in the washing solution, the vanes being oriented so that the cullet is tossed progressively forwardly toward a discharge outlet of the drum, to remove buoyant contaminants from the cullet, a dewatering apparatus to remove excess water from the cullet, and a dryer for reducin

Abstract: A coin mechanism includes a coin conveyor provided with a hub on its front face, which rotates in a recess formed in the rear face of the cover plate. The hub reinforces the structural integrity of the coin conveyor, allowing the mechanism to accommodate large coins without diminishing the reliability of the rotational locking mechanism. Preferably the recess is dimensioned as a bearing for the frontal hub, which secures the coin conveyor against shifting due to wearing of parts so that the mechanism retains a high tolerance for measuring the diameter of the coin over a longer period of time.

Abstract: The invention provides a magnetic fuel enhancement device in which a series of magnets is disposed about the periphery of an activation chamber, and a fuel conduit passes through a magnetic field region defined between the magnets. In the preferred embodiment the fuel conduit passes through the device many times, repeatedly exposing the fuel to magnetic fields within the device and thus increasing the amount of energy imparted to the fuel before combustion, and a concentrating rod attracts the magnetic fields toward the center of the chamber to focus the magnetic fields through the fuel conduit.

Abstract: A collapsible panel particularly suitable for a partition or enclosure system. In the preferred embodiment each panel has a flexible membrane affixed to an extruded frame, the corners of the frame having hinges which alternately fold along the plane of the frame and perpendicular to the plane of the frame. The frame is thus collapsible in two directions so as to collapse to a very small cross-sectional area, and when the panel is opened the membrane is pulled taught, which imparts structural integrity to the panel and prevents billowing of the membrane in windy conditions. Connecting elements are also provided so that the panels can be connected together to form a self-standing enclosure, or affixed to scaffolding or any other suitable frame structure.

Abstract: The invention provides a rotary coin mechanism in which the mechanism is provided with a boss which projects into the rotational path of the token. The boss allows rotation of the token carrier only if a token seated in the token receptacle is provided with a recess or groove complimentary to the boss and configured to approximate the rotational path of the token. In the preferred embodiment the groove has a first portion which is in line with the boss and a second portion which is offset from the first portion and connected thereto by a cam surface. As the token cycles past the boss, the boss passes from the first portion into the second portion of the groove and lifts the token within the token receptacle at the perimeter measuring point, so that only if the second portion of the groove is precisely positioned in the face of the token will the perimeter measuring device allow the token to pass.
