Abstract: Olive or other fruit paste from which oil is to be recovered is spread upon and sandwiched between two filter mats which are in turn sandwiched between two filter plates. Filter plates have slots extending from within the plate to the outer edges. Additional layers of paste between filter mats and a filter plate between each layer may be added to form a stack which is then placed on a press. As pressure is applied, juice containing the oil to be recovered flows out of the paste, through the filter mats and out of the stack through the conduits formed by the slots in the filter plates. By providing conduits, flow length and flow resistance is dramatically reduced resulting in more efficient and faster juice extraction. Filter mats can be economically fabricated to any size or shape, have selectable flow rates to match the properties of a particular paste, can be repeatedly reused, and can be washed at the end of the season for storage.

Abstract: A universal hand held tool for harvesting fruit and nuts. Harvesting is accomplished by a plurality of specially shaped spring wire tines. Tines are covered with plastic to minimize fruit and tree damage. Passing through a guide bracket secured to a handle, tines are held by a retainer that slides along the handle. Moving the retainer along the handle adjusts the tine spacing to accommodate different sizes and shapes of fruit. Retainer can be locked in any of a number of selected positions. Extension handles of various or adjustable length can be attached to harvest the crop safely from the ground. Fruit, such as olives that will be used to make olive oil, can be stripped from the branches using a raking motion into a tarp or container on the ground. To harvest for edible fruit without allowing it to fall to the ground a removable container is easily attached under the tines to capture the fruit. The container is made from a pliable material with a resilient aperture to reduce bruising or damage to the fruit.

Abstract: A locking device is provided for a removable tailgate on a pickup truck which permits normal rotational use of the tailgate while the lock is installed. The device is comprised of two basic parts, a lock and a lockable clamp. The clamp is used to close the open portion of the receiving cup through which the shaft is passed when the tailgate is normally removed. The clamp consists of a "b" shaped clamp with bent apertured tabs at each end. The lock mechanism includes a short linear plunger shaft with a head on the end of the shaft outboard of the lock. The diameter of the head is larger than the apertures in the end tabs of the clamp, so that the clamp is held secure.

Abstract: A method and apparatus for printing through holes in ceramic substrates and the like. The substrate is held in position by means of a vacuum applied to an outer peripheral surface portion thereof. The deposited substance is pulled through the holes in the substrate by means of a closely regulated vaccuum applied only to an inner surface portion, the inner and outer vacuum areas being separated in a holder device by means of O-rings. A pressure-time profile which appears in a plenum closely adjacent to the inner chamber may be compared to a previously generated pressure-time profile reference and used to accept or reject parts.
