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.

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.

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measured by a pneumatically positioned linear potentiometer (69)/proximity detector (PX3) combination, the stop (61) is withdrawn and the drill enters a clamp (95), which grips the adapter shank of the drill.

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.
