  • Patent number: 3982482
    Abstract: An apparatus for automatically peeling fruit whereby a cutter blade is moved toward and away from the fruit as a function of the sensed impedance between the cutter blade and ground through the fruit so that substantially all of the peel is removed. In the preferred embodiment, a horizontal assembly presents a fruit to each of a plurality of fruit holders mounted on a vertical assembly so that each one of the presented fruit is impaled on a different spike of the vertical assembly. A plurality of cutter assemblies each mounting a cutter blade are moved toward and away from the fruit as it is rotated and moved upward to remove the peel. A control circuit includes a counter incremented by pulses from Hall Effect Switches which are energized by magnets mounted on the vertical and horizontal assemblies and controls movement of the assemblies to carry out a predetermined cycle.

  • Patent number: 3978733
    Abstract: A sampler for extracting core samples from a mass of sugar cane. The sampler is mounted on a fixed or movable support which includes a plate member on which the cylinder of an operating jack is mounted.The piston of the jack is secured at one end of a rod which has at its other end another piston for expelling core samples. A sleeve extends around a portion of the length of the rod and rotatably mounts a hollow cylindrical core cutter with a toothed cutting edge. A motor is mounted on the sleeve for rotating the core cutter. Selectively operable temporary securing fingers are provided on the sleeve of alternate engagement with a collar on the rod so that the sleeve, core cutter and rod are displaceable in unison by the jack for lowering and raising the core cutter into and out of a mass, and with the plate member for preventing the axial movement of the core cutter with respect to the support so that displacement of the rod displaces the other piston in the core cutter to expel the core sample.

  • Patent number: 3966174
    Abstract: A foundry mold or core blowing premix nozzle for use in connection with the kold core process. The nozzle contains a mixing chamber that allows thorough mixing to occur during the blowing process. Immediately after the blowing operation the nozzle may be cleaned of any residual sand/catalyst/resin mixture which would ordinarily set up and clog the nozzle if allowed to remain within the nozzle. This cleaning feature is provided by a push through shuttle that sweeps the mixing chamber and moves a turbulence inducing baffle, normally positioned within the chamber, to a position external to the nozzle where it may readily be cleaned.

  • Patent number: 3965809
    Abstract: This invention relates to a pitting needle and malfunction detector for use in automatic fruit pitting machinery. The needle has a bottom portion which is releasably fixed with respect to a holder. Movement of the bottom portion with respect to the holder as, for example, when a foreign object is struck, is sensed and, as a result thereof, an alarm is sensed and/or the machinery is stopped. In one embodiment, the needles are made in two parts and movement of one part with respect to the other is detected by a pressure sensor which is electrically connected to a power supply for the machinery to render it inoperative. In another embodiment, the needle is made in one part and the shank of the needle is releasably mounted in a holder bar which contains electrical, electro-mechanical, or pneumatic sensing means to detect movement of the needle with respect to the holder bar.

Extending downwardly from above into the sand being mixed are a plurality of centrifugal tools located eccentrically with respect to the axis of the bowl. These centrifugal tools are rotated in a direction opposite the direction of rotation of the central tool. The radially extending vanes of the central tool are configured with respect to the plurality of centrifugal tools such that only one vane is in simultaneous facing relationship to any of the centrifugal tools during mixing operations. The centrifugal tools are rotated about axes extending obliquely with respect to the axis of rotation of the central tool so that the spacing of the centrifugal tools from the axis of the central tool is larger at the top than at the bottom.

  • Patent number: 3952646
    Abstract: The apparatus is comprised of a frame which supports a plurality of conveying troughs, an upper rotating drum, a lower rotating drum and a stationary decapping blade. The strawberries are first deposited in the troughs which then convey the strawberries to the lower rotating drum. The strawberries are then deposited singly into one of a plurality of cylindrical carrier pockets which are disposed in a spaced relationship upon the lower rotating drum. Each of the pockets communicates with a source of sequentially applied air pressure. The upper rotating drum is in a closely spaced and parallel relationship with the lower rotating drum. A plurality of spaced ports are located in the upper drum and communicate with a sequentially applied vaccum source. The two drums are rotated in a timed relationship so that the pockets and ports come into sequential communication with each other at the same time a pressure and a vacuum is sequentially applied to the respective pockets and ports.
