  • Patent number: 4804093
    Abstract: A bowl feeder for separating damaged rolling bodies, for example nuclear fuel pellets, from sound ones includes a bowl (10) having a central conical section (12) for distributing the bodies radially outwardly towards a V-shaped circular channel (16) which ensures that the bodies are arranged end-to-end with the rolling axes orientated lengthwise of the channel. The channel (16) discharges the bodies one by one onto an outer sloping section (14) whose slope is sufficiently shallow to allow bodies with asymmetrical defects to resist rolling by virtue of the shift in their centres of gravity, while allowing defect free bodies to roll radially outwardly down the slope. A system of rails (22, 24, 26) with gaps (28, 30, 32) serves to separate defective bodies from those which are defect free, the latter being allowed to roll to the outer periphery of the bowl and eventually to a feed track (38) while the former are routed to a reject outlet (40).

  • Patent number: 4792049
    Abstract: A system and process for sorting and conveying articles consisting of discarded tires and debris from one site to another site. The system and process receives articles in bulk, and concurrently singularizes and conveys the separated articles. Various physical characteristics of the individual articles, such as weight and size, are determined as the articles are continuously conveyed. Those articles having a physical property outside of a predetermined parameter range are ejected from the system. The remaining articles are then accumulated into groups of articles based on a physical characteristic of each article such that the sum of the physical characteristics of the articles of each group will be above a minimum and not exceed predetermined maximum values. The group of articles is then conveyed as a unit out of the system for a following operation such as disposal of the articles.

  • Patent number: 4635798
    Abstract: An apparatus and method utilizing pressurized air discharged through nozzles to segregate a mixture of elements having either different geometrical characteristics or different masses. The mixture is placed in a container having a conveyor track, and is forced to move along the track, across a primary nozzle which forms the mixture into a single layer. The mixture then moves across a blow-off nozzle which propels one set of elements off the track and out of the container while the other remains within the container. A two stage separation may be used to optimize efficiency.

  • Patent number: 4593603
    Abstract: An asymmetrical vibrator is provided, which is actuated by compressed air. The vibrator operates in a case, which has two bores disposed parallel on opposite sides of the casing. One of the bores is smaller than the second bore and the piston operating in the small bore is called the slow piston, since it is actuated with air to a relatively slow motion and the piston operating in the second larger bore is called the fast piston, since it is moves at a larger speed when driven directly by the compressed air. The asymmetric vibration motion can be employed to transport materials upwardly in factories and assembly stations. The air operated asymmetric vibrators need low maintenance and do not entail the spark dangers caused by the presence of electrical wiring for electrical drive motors.

  • Patent number: 4569446
    Abstract: This relates to a method of and an apparatus for feeding a product which includes fines to a weigh hopper. In lieu of the usual feeder pan, the last feeder pan in the feeder system is a duplex feeder pan including an upper feeding pan or level and a lower feeding pan or level. The upper feeder pan is provided with selected apertures therein so that fines will be separated from the remainder of the product and directed into the lower feeder pan. During the normal filling of the weigh hopper, both the upper feeder pan and the lower feeder pan will discharge into the weigh hopper. When a pre-selected underweight condition occurs, at least a part of the product from the upper pan will be diverted from immediately entering into the weigh hopper, while the feeding of the fines will continue so as to bring the weight of the product within the weigh hopper up to the pre-selected weight with a minimum of overweight.

  • Patent number: 4418874
    Abstract: Methods and apparatus for storing a length of web push the web from such length into a coiled form, whereby adhesion tends to develop between turns of the web in the coiled form, effectively limiting attainable minimum web coil diameter. According to the invention, such adhesion is broken up at least intermittently and web is continued to be pushed into the coiled form to reduce the web coil diameter and accommodate the entire length of web in the coiled form. The mentioned breaking up may include changing static friction between turns of the web to dynamic friction and/or shaking the turns of the web at least intermittently. Where a curved recipient is employed for prompting the web into a coiled form, an electromagnetic vibrator having a plunger acting on the curved recipient at least intermittently may be employed. An aspect of the invention imposes on the web a curl assisting coiling thereof in a housing.
