  • Patent number: 4960198
    Abstract: A conveyor with one belt (10) that is operated at one speed (V.sub.1) and advances pieces of candy (3) distributed in rows (5) at one interval (6) across the direction (2) of travel and with another belt (26) that is operated at a speed (V.sub.2) that differs from the first speed and with the rows of candy deposited on it at an interval (7') that differs from the first interval. The facing points (24 and 30) of deflection of the first and second belt are positioned on a driven carriage (15) and create a migrating transfer point. An auxiliary belt (20) is positioned on the carriage between the two deflection points and has a drive mechanism that can be shifted between two auxiliary speeds in accordance with the direction that the carriage is moving in.

  • Patent number: 4925177
    Abstract: An automatic paper feeder presses the surface of copying paper loaded on a paper loading plate in a paper cassette against a paper feeding roller, and feeds the paper sheet by sheet in accordance with the rotation of the roller. When a paper detector provided at a downstream side of the roller does not detect the paper within a specified period of time after starting a paper feeding operation, the automatic paper feeder rotates the roller in the reverse direction, at the same time releasing the pressure between the paper and the roller, and then increases the pressure and rotates the roller in the forward direction to restart the paper feeding operation.

  • Patent number: 4795066
    Abstract: An elongated steel tube, adapted to be filled with a high fusion temperature sand is positioned in a stationary refractory nozzle and its supporting refractory bore of a steel pouring ladle bottom nozzle before molten steel is first poured from a steel making furnace into a refractory-lined pouring ladle and then subsequently poured through said nozzle under the control of a slide gate or a stopper valve either directly into a steel ingot mold or through an intermediate tundish into a continuous caster. The steel tube includes centering means, such as fingers, secured to the outside of the tube to substantially center the tube in the refractory nozzle and permit additional sand to be placed in the annular space between the nozzle bore and the sand tube. In this way, upon opening the bottom valve, the hydrostatic head of molten metal assures quick, full flow of molten metal, such as finished steel through the nozzle insert.

  • Patent number: 4060177
    Abstract: An elongated web of stamps comprising a plurality of stamps connected together by a backing strip or longitudinally spaced transverse rows of perforations and formed into a roll is used in the dispensing apparatus disclosed. The stamp web is moved from the roll through an opening in the housing the distance required to position the desired number of stamps to be cut from the web each time the apparatus is actuated. To accurately position the web so that the web is cut along a connection between stamps such as a row of perforations, the web travels over a freely rotating indexing wheel having ridges positioned to engage the web at the connection between stamps only.
