  • Patent number: 6230478
    Abstract: Apparatus and method for manufacturing helically wound insulated conductors with filament fillers includes first and second payoff stations for paying off a plurality of insulated conductors and elongate filaments of filler materials. These cable components are guided from the payoff stations to a closing die, and are arranged in positions suitable for twisting into a cable by a double twist machine to form a cable of twisted insulated components forming radially outwardly facing helical interstices each of which is substantially filled with another one of the filaments of filler material. Differential or incremental lengths of filler material are metered upstream of the double twist machine to compensate for the differences in the radial distances of the insulated conductors and filaments of filler material on the center or cable of the axis.

    Abstract: A roller over which advances a web of material such as paper, photographic film or the like includes a plurality of staves organized in first and second arrays with the staves of the first array alternating with the staves of the second array to provide surfaces for supporting the web. The staves are each individually mounted on the roller by separate spring legs which center the staves. Flanges are located at the ends of the roller to position the web laterally. When the web obliquely approaches the axis of the roller so as to helically advance thereover, the staves sequentially and independently shift axially due to engagement with the helically advancing web. After the web leaves the roller, the stave that the web was most recently supported by returns under the bias of the spring legs to its central, unbiased position. In this way, damage to the edges of the web, due to engagement with the flanges, is minimized.

    Abstract: A fruit destemmer leaving an endless conveyor belt made up of a plurality of counter-rotating metal rollers rotatably supported at each end by endless chains. The fruit destemmer has an inclined bed with a driven shaft at each end. Each driven shaft has a wheel at one end and a sprocket at the other with the positioning of the wheel and sprocket being reversed on the other drive shaft. The continuous chains are driven by spaced sprockets mounted on a shaft positioned below the inclined bed. A rotatably mounted shaft, having a wheel mounted on each end, presses each continuous chain into close contact with the driving sprockets. Any foreign matter which enters between an endless chain and a sprocket causes the endless chain to slip on the associated wheel thereby maintaining chain alignment. The rollers used to form the endless fruit conveying belt are made of hard anodized aluminum which has a surface pattern to reduce fruit skinning.
