Abstract: A system for mounting an RF tag to a conveyor trolley wherein the tag is embedded in a block of material shaped to fit within an annular recess formed between the hub and outer rim of the trolley wheel. The shaped block is secured to the wheel.

Abstract: An apparatus for draft control and debris collection in a downdraft metal cutting table includes one or more partitions positioned beneath the work surface of the table which divide the table into a plurality of suction zones, each of which communicate with a suction source. Each suction zone is equipped with a damper positioned to selectively control airflow through the respective suction zone between the suction source and the work surface. Each damper includes a damper flap having a proximate end pivotally connected to the table. Actuators selectively open and close the damper flaps. When the flaps are open, a distal end of each flap extends downwardly from the proximate end. Slidably removable debris collection receptacles are positioned beneath the dampers such that when said dampers are open, debris falling through the work surface is directed into the receptacles by the damper flaps.

Abstract: A system for mounting an RF tag to a conveyor trolley is disclosed wherein the tag is embedded in a block of material shaped to fit within an annular recess formed between the hub and outer rim of the trolley wheel. The shaped block is secured to the wheel.

Abstract: The present invention is a trailer extension support dolly with a frame supported by a pair of articulating, free castering support wheels. The trailer extension support dolly attaches between a trailer and a tow vehicle to at least partially support the tongue weight of the trailer. The trailer extension support dolly is attached to the trailer via a conventional ball and socket and a pair of linkage arms extending from the trailer extension support dolly frame rearward to the trailer hitch bar. Each of the trailer extension dolly support wheels is mounted on a respective stub axle which is attached to an articulating axle support bracket via a swivel mount so that each wheel is allowed to caster during turning operations. In order to provide proper castering while going either in a forward direction or a reverse direction, the angle of each axle support bracket is adjustable so that the stub axle swivel connection can be selectively angled forward or rearward.

Abstract: A scale system for the continuous weighing of a series of packages on a conveyor. The packages are run over a series of synchronized belts on tables, one of which records the weight on a section of the conveyor at intervals timed to assure that no single package will be weighed more than once.

Abstract: A weighing system for material suspended from a rail or trolley. The system includes a transition track between the regular track and the weighing track to avoid oscillation of pressure on the weighing track which causes difficulty in rapidly arriving at a proper weight. The transition track is biassed away from the weighing track so as not to cause a false weight reading. It also includes a novel trolley moving mechanism for moving the trolley as it passes over the weighing mechanism.

Abstract: A control device for trolley shackles used to carry animal carcasses or parts thereof on a track for weighing and disposal. The control comprises a snubber device including extending teeth adapted so that each tooth can catch a shackle. Speed control of the teeth and their carrying device may be controlled by electrical or hydraulic devices in addition to mechanical brakes.

Abstract: A system for the continuing identification of carriers of meat carcasses and the like and the carrier involved in the system. The system involves mechano-visible identification of a pattern of uniform sized holes within a matrix on the carrier.
