  • Patent number: 4928473
    Abstract: A kind of automatic rotary weighing and packing machine having a plurality of weighers radially or annularly arranged on a circular rotary table for automatically effecting such processes as filling of product, weighing and judgement at respective positions around the table, which is especially suitable in the case where the product to be packed is sticky granular or powdered bulk material and the packing container is a bag or the like. This machine uses no weigh hopper or bucket in which sticky product is liable to remain to cause weight error, and the packing container is held by a holding mechanism attached to each weigher and directly filled with product, which is then weighed and sealed. A fixed amount feeding device is used for feeding product into the container and its throughput is controlled based upon the result of a subsequent weighment for keeping the weight of product packed in each container always at a predetermined value.

  • Patent number: 4873632
    Abstract: The apparatus reduces scatter in radiation imaging and may be used with a detector of ionizing radiation that is partly unscattered and partly Compton scattered. The detector produces an energy signal representing values of energy of the radiation and produces coordinate position information for the radiation. Data storage means for holding numerical values and means for displaying an image based on the numerical values in the data storage means are also used with the inventive apparatus. The scatter reduction apparatus includes circuitry responsive to the energy signal from the detector for producing first and second signals which indicate whether each value of energy represented by the energy signal at a given time is in a first energy range or in a second energy range less than half as wide as the first energy range and having at least some energies in common with the first energy range.

  • Patent number: 4845911
    Abstract: A framing system comprising a sash having a top rail member, a bottom rail member, and a pair of stiles interconnecting the rail members at opposite sides of the sash, and a muntin framework inside the sash for supporting and separating a plurality of individual lights, such as windowpanes. The muntin framework comprises at least one exterior muntin bar extending generally vertically between the top and bottom rail members, at least one exterior muntin bar extending generally horizontally between the stiles, a plurality of interior muntin caps, at least one generally vertical connecting bar connecting said vertical muntin bar and a respective muntin cap, and at least one generally horizontal connecting bar connecting said horizontal muntin bar and a respective muntin cap.

  • Patent number: 4768550
    Abstract: A manifold fitting for a compressed air tank having an elongate main body of hexagonal cross-section with first and second ends, the first end being of reduced circular cross-section, the body having an axial passage extending from the first end toward and terminating short of the second end. The first end is externally threaded for attachment of the fitting to a tank for communication with the tank via the passage. The body has a lateral opening extending inwardly from a one of its six faces to said passage and a pressure relief safety valve at the lateral opening in the body. A passage extends across the body and intersects the lateral opening.

  • Patent number: 4708564
    Abstract: Palletizing apparatus having an air table pivoted on a compression plate, the table being swung up to a raised inclined position for receiving bags to be stacked on a pallet from an infeed conveyor with the bags arranged in a layer on the table, and swung down to a lowered position and moved to a retracted position below the conveyor for withdrawing the table from under the layer of bags for deposit of the layer to form the stack on the pallet, the pallet being held on an elevator, the bags on the pallet being compressible against the bottom of the compression plate by raising the elevator, and a pallet magazine below the conveyor from which a pallet is transferred to the elevator on each cycle of the apparatus for the stacking of bags on the pallet.

  • Patent number: 4220346
    Abstract: A utility cart comprising an upwardly extending frame, a pair of wheels journaled on the lower end of the frame at opposite sides of the frame, and a bed pivoted adjacent one of its ends on the frame at the lower end of the frame for swinging about an axis extending from side-to-side of the frame between an extended position in which the bed extends forwardly from the frame in a generally horizontal direction and an upright position in which the bed extends upwardly alongside the frame at the front of the frame. The bed has a support at one end extending forwardly from the bed when the bed is in its upright position for supporting an object to be carried on the cart. Legs at the other end of the bed support the bed in its extended position. The bed can be selectively locked to the frame in its extended and upright positions.
