Patent number: 5305888Abstract: A floatation separation method is described for separating pieces of fruit or vegetable of the same type, but wherein desirable pieces have a slightly different specific gravity from the undesirable ones, and all have a specific gravity about the same as that of water. The pieces (12, FIG. 3 ) are placed near the surface of a body of water, and a cloud (40) of tiny air bubbles is maintained in the water. As the bubbles float to the surface they encounter the articles and slightly increase their buoyancy. The increase in buoyancy is slight and uniform, so those articles having a density slightly greater than that of the water will remain at the water surface, while those of a slightly greater density cannot be floated by the air bubbles and will sink to the bottom. The cloud of air bubbles is created by allowing air at about atmospheric pressure, to emerge from apertures in a rapidly spinning rotor that open in a direction primarily opposite to the spin direction.Type: GrantFiled: July 27, 1992Date of Patent: April 26, 1994Inventors: Donald M.

Patent number: 4925691Abstract: A method and apparatus for pitting olives and then slicing the pitted olives. In a preferred embodiment, each olive is carried in a cup positioned between a coring knife and a pitting knife in a manner so that the longitudinal axes of the cup and the knives coincide. As the cup and knives rotate around a drive shaft along parallel circular paths, a system of cams extends and retracts the knives relative to the cup, in order to pit the olive. After the pitting operation, the cup (containing a pitted olive) continues to rotate along its circular path past a set of slicing knives or water jet cutters. The slicing elements are oriented substantially parallel to the plane of the cup's circular path, so that the slicing elements will sever the olive cleanly into slices as the cup translates past them. In the inventive method and apparatus, both the pitting and slicing operations are performed on each olive while the olive is held in a known orientation.Type: GrantFiled: September 2, 1988Date of Patent: May 15, 1990Assignee: Ashlock CompanyInventor: Fred J.

Patent number: 4871568Abstract: A method and apparatus for pitting olives, in which each olive is held between a pair of matching knives as the knives are rotated along parallel circular paths by a rotating drive shaft. The knives may both be coring knives or may both be pitting knives, and are aligned so that their longitudinal axes coincide and the common longitudinal axis is substantially perpendicular to the plane of the olive's circular path. As the knives rotate along parallel circular paths, they are translated by cams along their common longitudinal axis so as to penetrate opposite ends of the olive simultaneously and then to push the pit out through one end of the olive. The coring knife embodiment of the invention leaves a clean bore through the pitted olive after removal of the core (including the pit), and prevents the pit from tearing away an irregularly shaped olive portion during removal.Type: GrantFiled: March 23, 1988Date of Patent: October 3, 1989Assignee: Ashlock CompanyInventor: Fred J.

Patent number: 4158993Abstract: A torque-type pitter for pitting drupes such as cling-stone peaches and the like, having coplanar, body-bisecting and pit-holding blades, and coaxial elements for gripping the peach body at opposite sides of the plane of said blades for twisting the peach halves from the blade-held pit. One of said blades has pitting knives or a pitting spoon in the plane of said blade that are normally inoperative where the pit in the peach between the blades is sound, or momentarily appears to be sound, but upon said blade passing between the halves of a split pit without hesitation, said knives or spoon will automatically be projected into the gripped halves to positions in which the rotation of said halves by said elements will spoon-pit the halves.Type: GrantFiled: November 17, 1977Date of Patent: June 26, 1979Assignee: Filper CorporationInventor: Henry L. Spence

Patent number: 3987948Abstract: A single-stone containing fruit of the drupe family is laid open to permit removal of the stone and implanting of a filling, if desired, by centrally impaling it on a row of tines, every other one of which is held on one half of a split platform with the remainder being held on the mating other half of the platform such that when the split platform is forceably opened the fruit is torn open exposing the stone. The row of tines has tines of lesser length in mid-portion to accommodate the stone and an overhead moveable bar carries a mating row of tines that pierce the fruit above the stone. This bar can be carried on a strike arm adapted to engage a strike plate on one of the platform halves and force the platform to open when the bar is forced downwardly as by being struck smartly with the hand.Type: GrantFiled: May 19, 1975Date of Patent: October 26, 1976Inventor: Lester Grant Peters

Patent number: 3962474Abstract: Pitted olives are stuffed with an edible food that has been dried to facilitate its handling, and the dried food is reconstituted within the pitted olives by packing the stuffed olives in an aqueous solution. Drying an edible food, such as pimiento, is carried out to cause an increase in stiffness and a drying of the surface texture to permit gripping of the food without slipping. Also, a reduction in size will accompany the drying of the food particularly if air drying is used. With this reduced size condition of the food, greater clearance can be allowed between the walls of the olive pit cavity and the sides of the food to be inserted since the food will swell to a tight fit within the pit cavity upon subsequent reconstitution. The stiffness of the dried food will be greater than that of the olive adjacent the walls of the pit cavity so that the walls of the pit cavity will deflect outwardly to receive the dried food if the dried food is somewhat oversized or slightly out of alignment.Type: GrantFiled: May 31, 1974Date of Patent: June 8, 1976Assignee: FMC CorporationInventor: William W.
