Abstract: A flexible barrier system is described that can be lowered or raised from a remote location using an accompanying remote control device which is either lockable or not lockable. The motor and mechanics used to raise and lower the chain are modular for easy repair and replacement, and enclosed in a protective covering in order to protect them from damage or tampering.

Abstract: A microwave resistant mixing device that is particularly useful for food preparation utilizing a motor which includes a moving mixing arm or paddle. The motor is further provided with a coupling for detachably mechanically linking the mixing arm to the motor. A housing provides a wall that forms a chamber to contain the motor. The housing also is constructed with an opening that provides access to the mixing arm coupling of the motor. A first shield prevents microwaves from entering the housing chamber through the housing wall. A second shield prevents microwaves from entering the housing chamber through the opening in the housing wall.

Abstract: A fruit pitting apparatus including at least one of a box cam assembly for driving pitting knives relative to holders containing fruit, an active separating assembly which improves the efficiency of separation of the pitted fruit flesh from the holders after pitting, and a wiping blade positioned to wipe pits from the holders after pitting. The holders can be driven continuously during the pitting operation, or they can be driven intermittently so as to be stationary during pitting and to translate before and after pitting. The separating assembly preferably includes actively driven cam tracks within the knife driving assembly which vary the force with which the holders grip the fruit during and after pitting, especially when the holders are driven intermittently.

Abstract: A pitting knife drive assembly for mounting in a fruit pitting apparatus to drive pitting knives of the pitting apparatus. The pitting knife assembly includes a box cam, a drive assembly for rotating the box cam, a pivot unit which undergoes reciprocating pivoting motion in response to the rotating box cam, and a set of one or more shafts which reciprocate longitudinally in response to the reciprocating pivoting motion of the pivot unit. Preferably also, the pitting knife assembly includes a subassembly for causing the shafts to undergo reciprocating motion in directions perpendicular to their longitudinal axes. A preferred implementation of this subassembly includes a carriage driven by a rotating eccentric, where the eccentric and the box cam are mounted along a common drive shaft, and the drive assembly includes a motor for rotating the drive shaft.

Abstract: An apparatus for pitting articles such as prunes or dates. Each article is loaded between jaws of a chuck assembly which translates between stations along a process path. At a pitting turret, a pitting rubber moves below the chuck assembly, and the chuck assembly and rubber translate together until a pitting knife engages the article and ejects a pit therefrom. The chuck assembly then translates the pitted article to a station where the pitted article is discharged. Preferably, a relatively large number of chuck assemblies are provided, each having a fixed jaw fixedly attached to a chain and a sliding jaw slidably mounted to the fixed portion. A relatively small number of pitting rubbers and one pitting knife for each rubber are mounted to the pitting turret.

Abstract: An apparatus for producing helical slices of an object, such as a potato. The apparatus includes a rotatably mounted knife assembly having one or more sets of knife blades arranged in a spiral pattern. Each set of knife blades produces a set of helically shaped potato slices. The spiral arrangement of each blade set reduces the torque needed to slice an object using the knife assembly. In a preferred embodiment, the inventive apparatus includes two sets of slicing blades, for producing two sets of intertwined helical product slices. A curved separator tube, which extends downward from the slicing blade area, disentangles the pair of intertwined slices having the smallest radius, as the blade assembly and the separator tube rotates as a unit.

Abstract: A device removing the stem and blossom portions of fruit utilizing a support for the fruit which is capable of orienting the stem or the blossom portion of the fruit in an upright position. The support permits access to either the stem or blossom portion of the fruit and is spanned by a pair of fruit reamers. Each fruit reamer is capable of completely dressing out the stem and blossom portions of the fruit when the first and second reamers are brought toward one another.

Abstract: A method and apparatus for producing helical slices of an object, such as a potato. The apparatus includes a rotatably mounted knife assembly having one or more sets of knife blades arranged in a spiral pattern. Each set of knife blades produces a set of helically shaped potato slices. The spiral arrangement of each blade set reduces the torque needed to slice an object using the knife assembly. The knife assembly includes a knife bearing rotatably mounted within a housing. To rotate the knife assembly, a gear rotatably mounted on a mounting member engages and drives an outer annular surface of the knife bearing. A liquid is injected through a channel within the knife bearing housing, and preferably also through a channel within the gear mounting member, to flush fragments of the objects being sliced from the knife assembly and gear.

Abstract: An apparatus for slicing objects, such as potatoes, with a rotatably mounted knife assembly. Objects (such as potatoes) to be sliced are conveyed downward toward the knife assembly between a gripper chain and a feed chain. A pair of springs provide a biasing force which urges the chains together, thereby ensuring that the conveyed potatoes are fed positively and uniformly toward the knife assembly. Preferably, two feed rolls having teeth are mounted between the lower ends of the chains and the knife assembly (each feed roll at the end of a rotating, slidable shaft). The teeth of the rotating feed rolls grip each potato conveyed against them by the chains, and force each such potato downward against the rotating knife assembly. Preferably, a support and retaining plate is fixedly mounted to the feed mechanism to constrain vertical movement of the feed rolls as they rotate with a potato gripped between them.

Abstract: An apparatus for severing fragments (such as fleurettes) from a one-piece core of an article, such as a cauliflower, as the article is translated between stations along a process path. In a preferred embodiment, the article is translated through a sequence of stations, including a coring station, along the process path. At the coring station, the article is held in a fixed position by an impaling knife or pin, while one or more rotating coring knives are lowered into engagement with the article by a pivoting arm mechanism. The pivoting arm mechanism causes each rotating knife to trace out a generally helical path as it cores the article.

Abstract: A method and apparatus for severing fragments (such as fleurettes) from a one-piece core of an article, such as a cauliflower, as the article is translated between stations along a process path. In a preferred embodiment, the article is loaded on a rotary table at a first station, then deleafed (or otherwise trimmed) at a second station, then aligned by a set of alignment rollers while translating through third and fourth alignment stations, then cored at a fifth coring station, and finally unloaded at a sixth station. At the coring station, the article is held in a fixed position by an impaling knife (or pin) while a set of rotating coring knives are lowered into engagement with the articles by a pivoting arm mechanism. The pivoting arm mechanism causes each rotating knife to trace out a generally helical path as it cores the article.
