  • Patent number: 4382516
    Abstract: A sorting method and apparatus for sorting steel products such as bars, rods, shapes and tubular products which are delivered in a random manner, according to the ordered lengths, sizes and so forth. The steel products are made to stay on a sorting apparatus temporarily. Then, pieces of products of the same class are successively selected and forwarded to a bundling bed from the sorting apparatus, while the latter receives a new piece of steel products. This operation is repeated for successive classes to sort the steel products into a plurality of classes having different ordered lengths, sizes or other sorting condition. The sorting apparatus has a vertically movable sorting roller table and a sorting truck arranged in a side-by-side relation to the sorting roller table and movable in the direction normal to the direction of movement of the steel products.

  • Patent number: 4381235
    Abstract: A screening apparatus comprising a rectangular screening frame and a multiplicity of parallel wires which are tensioned across the screening frame has a plurality of support bars with guide slots in order to support additionally each wire. The support bars are axially rotatably and interchangeably secured to the screening frame thus allowing to use the same screening frame for different string assemblies with different distances between the wires.If guide slots for different wire spacings are provided at different sides of a support bar, the same frame and the same support bars can be used for different string assemblies.The arrangement according to the invention allows an easy and rapid change of string assemblies on the same screening frame.

  • Patent number: 4380295
    Abstract: Drills (35), vertically oriented in a row/column array in a drill block (31), are moved in the column direction across a slot (49) located at a loading station (41). As the drills in each partially or fully occupied row reach the slot and drop, drill block movement halts. Thereafter a vertically oriented turn-over tube (51) is moved in the row direction beneath the slot (49). When an occupied drill position is reached, the drill drops into the turn-over tube, tube row movement temporarily halts, and the tube is rotated. The drill slides out of the turn-over tube (51) and down the channel (59) of a measuring station (43) until it hits a movable stop (61). After drill diameter is measured by a pneumatically positioned LVDT (87) and overall drill length is measured by a pneumatically positioned linear potentiometer (69)/proximity detector (PX3) combination, the stop (61) is withdrawn and the drill enters a clamp (95), which grips the adapter shank of the drill.

  • Patent number: 4380296
    Abstract: The invention comprises a circular, transparent, plastic disc having a plurality of circular holes located equidistant from the center of the disc and being substantially equidistant from each other. A plurality of radial tabs equal in number to the number of holes and located on radii corresponding to respective holes provides a device wherein a plurality of strands of yarn are cut into substantially equal lengths and divided by color. The yarn of like color is inserted through a hole, and a central portion of the yarn is pulled over a tab corresponding with the hole on its radius, thus locking the strands in place relative to each other and the disc. The disc can be mounted on posts extending from a "lazy-Susan" base.

  • Patent number: 4375264
    Abstract: A method and apparatus is provided for segregating and separately recovering fractions of a mixture of low density solids and high density solids, such as mixtures of clam shells and free detached clam meat. The mixture of solids is submerged in a laminar flowing stream of liquid which has a specific gravity about the same as that of the low density solids and such that the low density solids are substantially non-buoyant in the liquid. The bottom of the laminar flowing stream of liquid is defined in part by an upper foraminous conveyor surface which is moving in the same direction as the laminar flowing stream. The mixture of solids is flowed across a turbulent zone of rising air bubbles, and low density solids are removed from the top of the liquid and high density solids are removed from the bottom of the laminar flowing stream. Advantageous apparatus embodiments are provided for conducting the method.

  • Patent number: RE31169
    Abstract: Method, apparatus and system for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. Conveyor belts transport the objects to be sorted along the zone for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilience are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. By adjustment of frequency of the sorting zone oscillatory surfaces, a multistage sorting system is made available.
