  • Patent number: 6119842
    Abstract: A combinatorial weighing apparatus that combines articles after aligning same. The articles are input to the apparatus via hoppers, which can be selectively discharged to an alignment tray based upon the weight of the articles within the hoppers. A predetermined weight, or at least a weight within a margin of error of the predetermined weight, is discharged through a chute to an alignment tray. The chute narrows from an inlet position to an outlet position, and aligns the articles as they pass therethrough. Once in the alignment tray, the tray is shaken in an unsymmetrical manner so as to further align the articles. Once the alignment is complete, a gate beneath the tray opens and the aligned articles drop into a receptacle. The present invention is particularly useful in aligning elongate articles, such as bread sticks, and other food stuffs.

  • Patent number: 6119625
    Abstract: A method and apparati for preparing and displaying a donut having a "fresh-baked" quality in a retail environment principally uses standard equipment available in a typical convenience store or quick-service restaurant. The method utilizes pre-frozen donuts manufactured at a centralized manufacturing facility and involves thawing, storing and heating the frozen donuts at the point-of-service. The donuts are thawed under refrigeration but in a generally humidity-constant environment. This on-site procedure allows a retailer to quickly and conveniently produce a moist, fresh-tasting donut with minimum equipment and effort. Furthermore, the present production method allows the retailer to control the number and type of donuts produced for sale, thereby substantially eliminating waste and allowing the retailer to immediately tailor donut production to local consumer demand. An improved applicator eases the glazing process to permit relatively inexperienced personnel to properly glaze the donuts.

  • Patent number: 5012913
    Abstract: A device for singularizing bulk material includes an elongated trough having a longitudinal axis and a discharge end. The trough has an arcuate cross section and is inclined so as to slope downwards towards its discharge end. The upper end of the trough is connected to a motor which is capable of rotating the trough back-and-forth on its longitudinal axis. In operation, the trough is rotated back-and-forth and the bulk material is introduced into the trough at the upper end thereof. Due to the inclination and back-and-forth movement of the trough, the particles of the bulk material travel towards the discharge end of the trough along zigzag paths thereby allowing the trough to be shortened. The back-and-forth movement of the trough also causes the particles to bump into one another and push each other aside during the course of travel so that effective singularization is achieved.

  • Patent number: 4915258
    Abstract: A seed meter for metering individual seeds at a controlled rate into a furrow in the ground over which the seed meter is traveling releases the individual seeds into a hollow, elongated seed tube. The seed tube is curved along the length thereof in a direction opposite the direction of travel of the seed meter over the ground to release the seeds with a horizontal velocity generally equal and compensate for the motion of the seed opposite that of the seed meter. This enables each seed to reach the ground with little or no velocity component in the horizontal direction, thereby minimizing lateral seed bounce on the ground. Seed bounce within the seed tube is controlled and minimized by the tube curvature which gradually increases in a downward direction along the length of the seed tube. The inner front wall of the tube has logarithmic curvature from a generally vertical upper end thereof along an upper portion of the tube and exponential curvature along a lower portion of the tube.

  • Patent number: 4800875
    Abstract: Particulate bone is more easily and quickly guided into position for impaction into the site of a fusion mass by using a surgical funnel provided by an elongated, thin, flat base and a pair of thin, upstanding walls which extend along the elongated edges of the base to provide a chute. While the outlet of the funnel rests against the recipient site, particulate bond is incrementally pushed from the chute and tamped to build a fushion mass. By doing so, the particulate bone is much less likely to become contaminated by soft tissues. Preferably the reservoir provided by the upstanding walls is large enough to hold sufficient particulate bond to complete one side of a usual fusion mass so that the funnel can be left in position during that part of the surgical procedure. The funnel can be a single piece of metal or plastic.

  • Patent number: 4796887
    Abstract: A gutter structure has a trough-like gutter substrate positioned adjacent the bowling lane. A sheet of high density polyethylene material is applied to the upwardly exposed surface of the substrate so as to provide a highly durable finish to the gutter that is not harmed by lane cleaning agents. One edge of the high density polyethylene sheet may be stapled in a countersunk fashion to secure the liner to the substrate. The other edge may be tucked under the lane divider cap. The liner may be glued to the substrate at either end to avoid tearing away of the liner from the substrate.

  • Patent number: 4792031
    Abstract: An improved product filler collar is provided including an upper funnel portion for receiving charges of product from separate sources, guide ribs on the funnel portion for directing and controlling product flow and a neck portion for forming a single stream of product for filling a package or the like. The guide ribs may take the form of raised flanges forming a wall to confine relatively large product pieces. The flanges terminate in reduced extensions in the neck portion angled slightly back toward the product flow. The filler collar eliminates the bridging and swirling of product to prevent jams and decrease the residence time of the changes within the collar, thus improving the overall efficiency of the packaging operation.

  • Patent number: 4715487
    Abstract: A chute for an optical selector has a corrugated bottom surface in order to insure that particulate articles to be selected flow linearly and are dispersed uniformly across the width. The corrugations along the bottom surface of the chute are gentle having a small ratio of height to pitch of corrugation, and such corrugations provide shallow valleys which extend linearly from the upper infeed end of the chute to the lower discharge end. When the particulate articles to be selected flow down the chute, they accordingly flow in a linear way rather than following a curved path, but if the flowing quantity becomes so great as to normally cause a vertical piling up at the discharge end, the particulate articles will move sideways rather than piling up.

  • Patent number: 4693355
    Abstract: An automatic combinatorial weighing apparatus includes a double collection chute assembly disposed in delivery paths for passage of articles to be weighed. The double collection chute assembly includes an inner collection chute having an outlet and a pair of outer collection chutes having respective outlets, the outlets being connected to timing hoppers, respectively. Articles flow down the inner and outer collection chutes at as equal speeds and in as equal times as possible, the speeds being increased as much as possible, due to valleys created by flat plates which form the chutes. To prevent an increase in noise produced by hitting engagement of the articles with the chutes as the articles flow down the chutes at high speeds, a vibration damper having a vibration-restriction damping capability is disposed in an area of the delivery paths for damping the vibration to suppress the noise.

  • Patent number: 4660469
    Abstract: A shear system for processing scrap is provided that includes guiding and catching walls for enhancing the loading of large items into the shear system. A tiltable hopper is provided with an open rear so that very large and long scrap items may be processed. The hopper is tiltable so that scrap items may be loaded with relatively smaller apparatus. The system operates to precrush the scrap material taking advantage of leverage yielded by using pivoting wing and flap crushing surfaces. Crushing forces are essentially relieved prior to shearing to decrease the likelihood of jamming of the shear head. The system is modular and may be shipped to and erected in remote locations where electric power for operating the system is not available. The system includes an enclosed and protected area for the power plant and control station.
