Abstract: Jam reducing apparatus for use in coin operated machines, such as telephones, acts to prevent the insertion of coins when the entryway is obstructed by foreign matter, assists in dislodging jammed coins and discourages vandals. The apparatus comprises a coin entryway which includes an inclined surface as part of a flared end of a lid. An entry slot in an entrance blocker, which is an integral part of the lid, as in substantial alignment with the coin insert slot of the front panel of the machine in normal operation. The lid is connected to a torsion spring and is associated with a coin reject lever. The inclined surface of the entryway lies opposite the blocker slot and is angled toward an exit of the coin entryway, which directs a coin into the machine. In normal use, inserted coins pass through the entryway and are directed into a coin mechanism for coin testing. Foreign matter inserted into the machine hits the inclined surface and exerts a camming force on the lid, rotating the lid about a torsion spring.

Abstract: An artificial fog generator device is provided with air jet pipes, an oil bath, filtering screens, and an enclosing housing to include all of these elements, and outlet channels for directing the generated cloud of oil bubbles from the housing, and an air compressor that feeds high pressure air into the spraying pipes. A much more efficient generator of fine oil bubbles is achieved by locating the air jet pipes directly above the surface of the oil bath. The compressed air is fed into the pipes that are located directly above the oil bath and high pressure air jets spraying into the oil bath cause a cloud of fine oil bubbles to fly out of the oil bath. The generated oil bubbles than pass through the filtering screens and are then directed out of the housing through the outlet channels. The fog or smoke generator housing may be portable, and have a carrying handle, and may contain the air compressor, and a power supply and battery to power the air compressor.

Abstract: Apparatus for spreading manure comprises an elongate hopper 12 mounted on a mobile frame. An axial feed rotor 18 runs along the inside of the base of the hopper and urges manure forwardly to a transfer rotor 25 which pushes the material sideways through an opening 21 to an overshot impeller 23 which throws the manure sideways from the apparatus. On the axial feed rotor 18 are blades 19 extending outwardly from the axis of the rotor and inclined in such a manner as to push the material along the direction of the axis. The blades 19 are positioned on a reverse helical path around the rotor axis, the sense of the reverse helical path being opposite to the sense of inclination of the individual blades. In this arrangement the efficiency of axial delivery of the rotor 18 is substantially lower than if the blades were positioned along a helical path around the rotor axis having the same sense as the inclination of the individual blades.

Abstract: In valves having flat armatures, in order to attain the shortest possible switching times, the goal is to to reduce the mass of the armature and the surface area of the stops. A particularly advantageous design is obtained by embodying the flat armature in the manner of a gear wheel and providing at least three radially extending teeth, spaced uniformly apart from one another, on which the stop lobes that cooperate with a stop integral with the housing upon actuation of the valve by excitation of the magnetic coil are formed. A flat armature embodied in this way can be used in any correspondingly embodied valve.
