Abstract: A multiple channel peristaltic metering pump includes a base having a pair of spaced apart bearings, a rotor supported on the base and an occlusion member. The rotor includes a rotation shaft in the bearings and a plurality of rollers mounted thereon. A pair of occlusion rings, which are located concentrically with the rotation shaft by the bearings, position the occlusion member with respect to the rollers. Each of the rollers is rotated about a bearing which is located in an opening having sufficient size to allow expansion of lubricant under high operating temperatures. A hose expansion space adjacent the rotor takes up any elongation of the hoses in order to avoid crimping. Hose spacers in the expansion space prevent hose creep along the rotor.

Abstract: A spray unit and process for controlled droplet atomization in which a tangential vortex type fan with wide mouth passes operation from low-to-medium pressures at high volume, passes air through a throat in which controlled droplet atomization of spray material is being achieved prior to emission from the fan in a plane generally parallel to the flow of air. The flow of air sweeps the droplets into a parallel orientation in substantial avoidance of contact of the spray material on the fan parts, throat or mouth thereof and the airflow confines the continuous core of controlled droplets and projects the protected spray toward a target. The spray units are arranged to permit plural end-to-end adjacent articulated mounting with directional adjustment and flexible conduits for power at the individual units, including spray material delivery and power to lineal actuators and are carriage mounted on wheels for easy movement in the target area.

Abstract: A harvester for picking cucumbers that is effective and cost efficient on small, "pickling" cucumbers is mountable on a tractor frame for a conventional mechanical pickle harvester between a vine cutter and pinch roller mechanism. The harvester comprises a pickup mechanism at the front of the harvester for picking up severed cucumber vines and a conveying and fruit removal mechanism that conveys the vines rearwardly between the pick-up mechanism to the pinch roller mechanism, while at the same time gently dislodging fruit from the vines and thinning and defoliating the vines so as to improve the action of the pinch roller mechanism. The conveying and fruit removal mechanism includes a rotating paddle mechanism comprising cushioned gum rubber paddle blades that rotate in the direction of vine travel and strike the fruit as the vines are conveyed over the paddles.

Abstract: A process and apparatus applicable to solid-set fruit growth such as strawberries in which a single harvest applies to an entire solid-set field and the harvest does not destroy the plants but separates foliage and trash from the fruit in an aerodynamic sequence and subsequent singulation of the fruit occurs under conditions of aerodynamic levitation of the fruits and clusters at the point of cropping connective tendrils.

Abstract: A machine for detopping fruits and vegetables, specially suited for the decapping of strawberries by severing the top therefrom, comprises an endless upwardly-inclined loop type conveyor mounted on a sub-frame which is in turn mounted on a main frame for horizontal orbital motion relative thereto. The conveyor consists of a receiving station section inclined to the horizontal so that already decapped product discharges against the travel of the conveyor, and a severing station section at a higher level than the receiving station section, a downwardly-extending discharge section and a return section. The conveyor consists of parallel rollers alternate ones of which are positively driven by pinion gears engaging rack members at the side, so that co-operating pairs will grip the tops. Only product that has been so gripped can be conveyed upwards by the conveyor and presented to a transversly moving endless band severing knife at the severing station.

Abstract: An inner portion of a conveyor comprising a plurality of pivotably joined crossbars having an open bottom receiving cup to hold a piece of drupaceous fruit is driven at a synchronized speed below a fruit feeder device. After the feeder device deposits a piece of fruit in each cup, the inner conveyor portion travels a short distance where it is joined by an outer portion of the conveyor comprising a like plurality of pivotably joined crossbars having an inverted covering cup with a perforated diaphragm top. The conveyor portions mate to partially enclose the piece of fruit within the cups. The fruit is conveyed through a pitting station where a star-shaped pitting tool is driven at high speed through the opening in the bottom of the receiving cup, into the piece of fruit to contact a pit of the fruit and push the pit upward through the perforation of the diaphragm in the covering cup. As the tool is withdrawn from the fruit, the fruit and its now separated pit are conveyed separately for further processing.

Abstract: A high capacity device for reliably sorting pieces of fruit from a bulk supply into individual cups for processing. The fruit is received in bulk in a hopper, a side of which is open to a center hub of a connected pair of feed wheels revolving coaxially in spaced horizontal relation. Each feed wheel carries a plurality of radially-extending through passages about its periphery. Each passage carries at least two individual pieces of said fruit simultaneously. An outward, exit end of each passage is normally blocked by cammable gate fingers. The feed wheels are rotatably synchronized with a pair of chains engaged with sprockets attached to the feed wheels and carrying therebetween a conveyor carrying the fruit cups. The speed of revolution of the feed wheels is sufficient to keep an outermost one of the fruit pieces lodged adjacent the gate fingers.
