  • Patent number: 4301719
    Abstract: Citrus peels discharged from a juice extractor are first comminuted with water to form a slurry, and thereafter the slurry of comminuted peels and water is screened to separate from the slurry a larger particle size fraction consisting mainly of the flavedo portion of the peels and a smaller particle size fraction consisting mainly of the albedo portion of the peels. A preferred apparatus for separating peels into albedo and flavedo fractions includes a comminutor which utilizes a cutting action to reduce the peels to finely divided particles. Water is added to the comminutor to fluidize the peels so as to facilitate their movement through the comminutor and also to facilitate subsequent screening. The slurry of water and comminuted peels is sifted using a vibratory screen having an upper screen of a 20 Tyler mesh size to remove the flavedo fraction from the slurry and having a lower screen of a 60 Tyler mesh to separate the albedo fraction from the remaining slurry.

  • Patent number: 4294059
    Abstract: An apparatus receives empty bins and loose articles of random size and shape, such as apples, to be stored within the bins at a fill station. The articles are delivered to an inclined conveyor which has a lower end adjacent to a horizontal conveyor with a stop roller being positioned between the conveyors. When the articles have collected on the inclined conveyor a predetermined distance up the incline, a drive is actuated which simultaneously moves the inclined conveyor upwardly and moves the horizontal conveyor away from the inclined conveyor while rotating the stop roller to permit the articles to move from the inclined conveyor to the horizontal conveyor. This conveyor motion causes the articles to gently cascade down the incline in spread out fashion so that they are transported toward the end of the horizontal conveyor remote from the inclined conveyor and across the entire breadth thereof.

  • Patent number: 4285240
    Abstract: An off-the-car wheel unbalance measuring system has a rotationally driven wheel mounting shaft supported in a pedestal together with a pair of force transducers mounted in the pedestal adjacent to and spaced along the shaft. The force transducers are coupled mechanically to the shaft and provide periodic electrical output signals indicative of unbalance forces transmitted through the shaft when the shaft is driven rotationally. The angular position of the shaft is monitored with respect to an angular reference position at a predetermined number of angular increments during each full revolution of the shaft. The transducer output signals are converted in electrical circuitry within the system to digital form, and a multiplication operation is performed on the digitized signals at each angular increment using sine and cosine representative factors corresponding to that particular angular increment.

  • Patent number: 4235482
    Abstract: A bushing is provided which is arranged to be press fit into a bushing bore. The bushing is adapted to support a high level load which is unidirectional or which changes in direction through only a small angle. A rigid core in the bushing has a long rubber, or rubber-like, semicylinder bonded to one side of the outer surface thereof and has a number of uniformly spaced short rubber semicylinders bonded to the other side thereof. The short semicylinders have a greater wall thickness than the long semicylinder so that when the bushing is pressed into the bushing bore the space between the core and the wall of the bore is practically filled on the short semicylinder side. The long semicylinder operates in compression to support the high level load without exceeding the rubber endurance limits and therefore avoids the effects of internal deterioration in the rubber.
