Patent number: 4446572Abstract: The nursing dress includes an outer dress portion covering the torso of a woman and having a given color and design. An under dress portion, in turn, covers the torso from the inside upper front margin of the outer dress portion and extends downwardly over the top areas of the breasts to within a short distance of the nipples and is of the same color and design as the outer dress portion. This under dress portion may be detachably secured to the inside of the outer dress portion at the shoulders and side arm areas. An exposing arrangement such as zippers or buttons on the front of the outer dress portion permits an area of the outer dress portion to be removed from in front of the torso to expose the under dress portion and an uncovered area of a breast for nursing a child. Since the under dress portion has the same color and design as the outer dress portion, it blends in with the remaining front of the outer dress portion to camouflage the fact that an area of the outer dress portion has been removed.Type: GrantFiled: August 12, 1983Date of Patent: May 8, 1984Inventor: Rosaland O.

Patent number: 4446610Abstract: A retrievable float valve hanger tool assembly provides a hanger sub having a first upper connection for attaching the hanger sub, for example, threadably, to a drill string or work string. A second lower connection means on the sub provides both external and internal threaded (for example) connections, which allow the sub to be connected on its inner threads to a float valve canister and at its external threads to an extension which forms a protective housing about the float valve and its valve canister during operation. The device places the float valve below the joint of the sub and the extension so that an explosive charge can be detonated at the joint allowing easy removal of the float valve from the drill string in the event that the drill pipe becomes stuck. A continuous bore through the assembly allows fluid circulation through the tool in the work string and also allows the explosive charge to be lowered by wireline, for example, to the tool assembly at the appropriate joint.Type: GrantFiled: May 4, 1983Date of Patent: May 8, 1984Assignee: Ace Fishing & Rental Tools, Inc.Inventors: Larry V.

Patent number: 4446615Abstract: Apparatus for successively attaching terminals to stripped ends of electric conductors which are delivered from a wire cutting and insulation stripping apparatus to a conductor supply zone in which the conductors are successively picked up by gripping jaws of finger assemblies carried by a conveyor chain and transported to a terminal attaching zone including successive spaced apart first and second terminal attaching devices, each having dies for crimping a terminal end portion to a received end of the conductor, and in which a conductor gripping mechanism in the terminal attaching zone is operatively controlled to axially move the conductor with a terminal attached to one end by the first terminal attaching means in a direction and for a period dependent upon its length to dispose its opposite end in a predetermined position for the attachment of a terminal thereto by the second terminal attaching device.Type: GrantFiled: March 16, 1982Date of Patent: May 8, 1984Assignee: Eubanks Engineering CompanyInventor: Lloyd A.

Patent number: 4446616Abstract: A semi-automatic, poly-sleeve labeler has a banding station to which containers are conveyed, there being a roll supply of flat, tubular, poly-sleeve labels above the station. A fixed, upstanding, flat, holder and an inclined, spring-biased, pivoted, flat, holder are mounted at a predetermined distance above the level of the conveyor path to support an open band. The operator tears off a band, places it over the holders, presses a pedal which causes a piston head to lift the container at the station, up through the holders for frictional engagement within the band. The banded container is removed and the parts return for the next cycle. A gear rack and pinion mechanism advances the bands individually and successively over a spreader to a tear-off location at about eye level. The spreader includes oppositely disposed concave recesses in each of which one of the oppositely disposed feed rolls is seated.Type: GrantFiled: December 17, 1981Date of Patent: May 8, 1984Inventor: Theodore Waterman

Patent number: 4446617Abstract: A splicing head for positioning multiple wire pairs of a cable for connection to an electrical connector is provided with a removably mounted comb to facilitate the addition of a second cable to a connector with a connected first cable. The splicing head has a bed for receiving a modular electrical connector with its sattached cable. The comb is then mounted by vertical supports on a backside of the splicing head. The comb has multiple wire guides. A second cable is placed adjacent the comb and its wire pairs are separated and placed in the wire guides. The ends of the wires of the second cable are then attached to proper contacts on the modular connector mounted on the bed which already carry the corresponding wire pairs of the first cable. The comb is then removed to allow removal of a connected unit consisting of the modular connector, the pre-connected first cable, and the newly connected second cable.Type: GrantFiled: February 16, 1982Date of Patent: May 8, 1984Inventors: Donald J. Lydell, deceased, by Hilda Lydell, executor

Patent number: 4446620Abstract: The invention relates to a tube cutter, especially for plastic tubes, which comprises a housing that can surround the tube and having a rotation guide gripping the tube. The tube cutter has a cutting tool which can be sunk into the outer surface of the tube, having a lengthwise guide and a tool holder movable therein. The cutting tool has a cutting edge which runs at an angle to the direction of movement of the tool holder and lies substantially in a plane passing through the rotational axis. By these means it is possible to produce bevels with the cutting edge.Type: GrantFiled: August 9, 1982Date of Patent: May 8, 1984Assignee: Rothenberger GmbH & Co. Werkzeuge-Maschinen KGInventor: Karl-Heinz Velte
