Abstract: A clean-out tool system for use with a oil well production tubing extending downward through a casing terminating in a production zone in the well bore, which zone is isolated by a packer and includes flow restricting debris to be cleaned out. A generally vertical, elongated, cylindrical tool body, having a relatively small diameter and a bore therein, is located down through the inner production tubing into the zone located at the end of a tubing string extending downward through the production tubing for communicating fluid pressure to the bore in the body. Four, peripherally spaced, elongated slots extend radially inward into the body with their longitudinal axes aligned with the longitudinal axis of the body and communicate with the bore in the body. An elongated blade is pivotally attached in each slot to the body, movable from a first configuration wherein the blade is positioned vertically within the slot, and a second, expanded configuration positioned radially outward in the zone.

Abstract: A vacuum packed, frozen, cooked or non-cooked shrimp pack, in which the shrimp-containing plastic pouch has a center thickness less than its outer, surrounding periphery, with more shrimp contained one above the other at the peripheral edges in comparison to a lesser number at the center in the pack. This produces a relatively even heating or cooking of the shrimp when the frozen pack is placed in a micro-wave for defrosting or cooking. Such a pack can be produced by providing an upwardly curved, rigid form underneath the bottom film layer of the pack in the "form, fill and seal" machine during commercial packing of the product in the sealing station and, if so desired, in the forming and fill stations. The rigid form can be provided by a curvi-linear section (FIG. 4) or a hemispherical section (FIGS.

Abstract: A mop drier attachment for a mop having a staff with a mop head element at one end, said attachment having a hook element for gripping the staff positioned near the mop head element. The mop head element includes a plurality of strands which are spread apart and flared out for enhanced, expedited drying by the attachment having a periphery defined by a wire having a pair of generally flared portions in a plane generally transverse to the axis of the staff which extend symmetrically to form a pair of generally arc shaped portions lying in a common arc on the plane and extending toward each other and joining together, the arc shaped portions defining a generally curved portion on which the strands are spread and flared apart for drying with each of the strands extending generally radially outward from the staff in a direction generally along a distance of a radius of the curved portion and then hang down in a generally transverse direction by its periphery in a direction generally along the axis of the staff.

Abstract: An improvement in chemical cutting apparatus for use down within a well bore comprising an automatic means of pressure relief, whereby the anchoring mechanism of the apparatus is disengaged automatically when a clogging of the chemical discharge ports or other malfunction occurs, which pressure relief prevents the cutting tool from becoming stuck down in the hole. The automatic means includes a pressure relief port in the form of an axial bore from the exterior of the assembly to the anchor slip chamber, situated in such a manner that the inside pressure of the cutting apparatus does not communicate with the exterior, until the anchor slip becomes erect. The relief also includes an expendable plug and "O" ring assembly, which acts to prevent clogging of the relief port prior to firing of the cutting apparatus.

Abstract: A down-hole oil field cable abrader having an elongated abrading head pivotally connected at one of its ends to a body attachable to a tubing string. An abrading portion extends axially along the abrading head from its pivotal connection and includes a plurality of abrading elements, similar to the cutting elements on a drill bit, spiralling axially about the abrading head ending in a taper to an area distal to its pivotal connection.

Abstract: A plastic cuff which has been sectioned and cut to fit a mooring line for a marine vessel and similarly shaped structures. The cuff may be tubular or cylindrical and provided with a spiral cut. It is treated with an insecticidal agent or made of an insecticidal material. If cylindrical, it is made with sufficient elasticity to maintain its shape, so that the cylindrical cuff may be wrapped around a rope or other extended cylindrical shape by means of opening the cuff along the spiral cut which travels the length of the cuff. It then clings to the rope due to the inherent tension of elastically attempting to resume its original shape. Alternatively, the cuff may be attached or retained by way of clasps on either end or by pins.

Abstract: A jarring apparatus for use with an electric line for upward jarring of a tool element stuck in an oil well including a tubular member having a tool element attached to its lower end. A hammer disposed in the tubular member is attached to a cylindrical rod for motion therewith by an electric line disposed through a longitudinal bore in the rod and is moved from a first configuration upwards to a second configuration by a quick, generally upward motion of the electric line toward an opposed anvil included with the tubular member, the quick generally upward motion of the cylindrical rod from its first configuration to its second configuration rapidly moving the hammer to strike against the anvil to provide a generally upward jarring action which is transmitted to jar the element in a generally upward direction. If the jarring does not loosen the stuck tool, disconnect means are provided for leaving the tubular member and tool element in the well but retrieving the electric line.

Abstract: A "spill-proof" bowl, particularly suitable for a child, for a dry, granular foodstuff to be eaten by hand, comprising a bowl having a hollow interior therein substantially covered over by a cover located on an open end of the bowl for substantially closing off the hollow interior. A tubular portion centrally located in the cover terminates with an inwardly curved edge at its lower extremity in a relatively small, open end for forming an open closure spaced in the hollow interior below the midpoint between the cover and the base to provide visual and selective access to the dry, granular foodstuff located in the hollow interior of the bowl when open. A portion of the tubular portion extends upwardly and terminates in an open, upper end spaced above the cover. A tubular passage depends downwardly through the tubular portion and communicates with the hollow interior of the bowl by means of the open closure means.

Abstract: A flexible, non-collapsible conduit system separable but positioned around a standard cuffed, endotracheal tube to allow for direct topical application of medicinal substances to tissues of the larynx and trachea that might be irritated, traumatized, or stimulated by the endotracheal tube. An external injection port and tubing connect to an internal passage in the endotracheal tube side wall, the passage extending to connect with a system of flexible, non-collapsible conduits, whose lumens are always patent, integrated and distributed above, about and below the cuff area of the endotracheal tube. This system of flexible, non-collapsible conduits are perforated to allow for infusion of topically applied medicinal substance(s), such as anesthetic or anti-inflammatory substances, directly onto those tissues so affected by the cuff and tube regardless of whether the endotracheal tube is completely inflated, partially inflated or completely deflated.

Abstract: A table designed for ease of use by the occupant of a wheel chair having a shaped, cut-back, front edge to allow the torso of the user to extend partially into the working surface, enabling the user to have ease of access to the entire working surface. A peripheral lip or ridge about the back and side edges of the table prevents articles from falling off and out of reach of the user, and the height and table top size are dimensional for use by a wheelchair occupant. The table has casters mounted on its rear leg portions but not on its front leg portions. The table is easily moved by the user who simply tilts the table to lift its front leg portions off of the ground, tilting the table onto the casters mounted on its rear legs, and then rolls the table with him. When the table is tilted for movement the peripheral ridge acts to keep articles on the table. When the table is at a desired location, its front legs are lowered back down into hold contact with the floor.

Abstract: An orthopedic heating or cooling system to be built into a cast or splint and bodily integrated with it as the cast is being applied to the patient. One or more individual units are used independently or in combination to form a flowing liquid system to heat or cool specific portions of the injured limb in a controlled fashion. The individual units include liquid carrying tubes held in a fixed, crossing pattern and integrated into the cast by means of an open mesh covering. Hot or cold fluid is pumped from a reservoir through one or more of the individual units in the desired sequence and amount and then expelled back into the temperature controlled or conditioned reservoir. In this fashion one may heat or cool the entire area under the cast or only specific sections, as desired, greatly increasing the comfort to the patient.

Abstract: Dress inserts for smoothing the contour lines of dresses improving the appearance in the bosom area and an improved manufacturing method therefor comprising the use of three cut pieces--an outer, liner, an inner lining smaller than the outer lining, and a foam padding layer which is sewn as a unit to and is sandwiched between the inner and outer linings, the method of manufacturing avoiding the need for any trimming step due to the overlapping of too much material. All three pieces have a general oval shape, with "left" and "right" versions begin mirror images of each other, with a triangular or pie shaped section cut out of each of the ovals, so that, when the two diverging edges created by removal of the slice are connected, a natural cone-shape is produced. Because the inner lining is smaller, it supports and raises the outer lining, with the padding providing for correct contouring.

Abstract: A lumbar traction system particularly suitable for home use, which includes a stand formed by an upper "H" frame member sitting on a pair of spaced, pivoting "X" type legs, with the stand being located near but spaced from the foot of the patient's bed with rope(s) extending from a traction belt or sling worn by the patient to the top, central part of the stand. Centrally located traction weights are suspended on the rope(s) within the stand between the "X" legs, with rearwardly placed, supplemental stabilizing weights (e.g. a water bucket or water bags) being added at the rear of the stand. Such an arrangement is highly stable and self-sustaining, notwithstanding the substantial resistive force of the patient under lumbar traction, and the substantial weight of the centrally located traction weight. A series of opposed sets of hooks are included on the underside of the "H" frame member to be selectively engaged by the cross-bars of the "X" leg frame member for varying the effective height of the stand.
