Abstract: A denture retention system includes a denture, abutments and an implant connected to each abutment. The denture has an inner channel with a resilient liner and engaging caps in the inner channel that releasably retain the denture on the abutments. The engaging caps each have a cavity that receives the head of an abutment. The cavities are sized with longitudinal space for the heads of the abutments so that the denture rests on the gingival tissue while the abutments restricts movement of the denture away from the gingival tissue. The system can be used with large diameter or mini implants. The separate implant and abutment allow precise selection of the abutment height. The abutment has a spherical head with tool engageable flats for tightening the abutment onto the implant.

Abstract: A denture retention system includes a denture and an abutment. The denture has an inner channel with an elastic liner having inserts. Each insert has an O-ring and a channel for capturing the O-ring. The abutment has a shaft, a head at one end of the shaft and a base at the other end of the shaft. The head has an undercut surface that extends radially outwardly from the shaft. The O-ring and undercut surface overlap and engage one another to retain the denture in the cavity. The abutment has a threaded portion at the other end of the shaft portion that threads into an implant or implants into a jaw, or a threaded aperture that receives a threaded portion on an implant.

Abstract: A denture retention system includes a denture and an abutment. The denture has an inner channel with an elastic liner having shaped cavities. The cavities have a shaft, a head at the closed end of the shaft and a concave ring between two convex sections on the shaft. The abutment has a shaft, a head at one end of the shaft, a protruding ring between two concave sections on the shaft and a threaded portion at the other end of the shaft portion. The surface of the cavity overlaps and engages the surface of the abutment to retain the denture in the cavity. The threaded part of the abutment threads into an implant or implants into a jaw. The cavity expands when the abutment is inserted or removed from the cavity, and contracts after insertion.

Abstract: A magnetic device used as a bookmark and a nametag. The device includes a strip of sheet material including first, second, third and fourth panels folded along first, second and third fold lines. First and second magnets, preferably of the rare earth type, are secured between selected folded panels forming clamping jaws that fasten the device to a page in a book or to clothing. Selected printed indicia information on the panels may display advertising, business card information, use instructions, and appointments so the device may serve as both a bookmark and a nametag.

Abstract: A fishing device including a pair of opposed first and second arms pivotally connected at a pivot to move between an open position and a closed position. The first arm has a first jaw head at one end and the second arm has a second jaw head at one end. The first and second jaw heads have opposed inside gripping surfaces and further having opposed cutting blade portions that cut in said closed position. A latch is connected to the arms for holding the arms in the closed position and releasing the arms for pivotal movement away from one another to an open position. A first pair of opposed first and second transverse grooves along the inside of the first and second jaw heads forms a line tie hole usable in tying a knot in a fishing line. A second pair of opposed transverse grooves along the inside of said first and second jaw heads at the front end forms an eyelet threading hole through which a line will pass to thread an eyelet held in said grooves by the first and second jaw heads in the closed position.

Abstract: A jaw movement recording device, articulator and methods disclosed utilize a lower marking plate with front, rear, left and right side marking pins that cooperate with an upper marking plate and depressions and a bearing pin in such a way as to give an accurate recording of the movement of a patient's lower jaw in a wafer between the two plates. An articulator has a lower frame with upright side posts having upper pin-like portions and an upper frame with fossa holders and a pliable material that form fossa socket patterns. Tension springs extending between the frames at the front and rear enable a constant tension in forming the fossa socket patterns.

Abstract: Apparatus and method are disclosed for forming a loop in a wire that is particularly suited for attaching a wire to a ceiling suspension bracket and allow free swinging movement of the wire on the bracket. The apparatus includes a wire storage and feed bin, support for each wire during the loop forming, a twist member, a control head that moves the wire to form a bend, a drive that rotates the twist member through a selected number of revolutions to twist the bend to form the loop, coils and a tail in the wire. Surface portions of the control head confine the movement of the wire during the formation of the coils and loop. A control circuit for the drive motor causes the motor to turn only a selected number of revolutions to form a selected number of coils. A final positioning assembly causes the twist member to stop at the same position after each loop forming operation.

Abstract: Shelf brackets are each in the form of a unitary body which has a vertical back wall. Defined in the body is a platform that projects outwardly away from the back wall a given distance and is inclined in the outward direction upwardly at an angle substantially between one-half and five degrees with respect to the back wall. Also defined in the body is a ledge that projects outwardly away from that back wall generally parallel to the platform. The ledge is spaced above the platform by an amount to accommodate receipt of a shelf board inserted between the platform and the ledge. Defined in the body is an opening for enabling securement of the body to a mounting surface. A further feature is an enlargement communicating outwardly from that opening that forms a channel which may accommodate receipt of an end of a hanger or the like. As shown, the ledge does not project as far outwardly as the platform.

Abstract: A ski sling is composed of first and second elongated hollow tubes, the first being the longest and the second being sized to fit within the first. A continuous loop, of adjustable length, of flexible cord runs in series through the interiors of those tubes. The length of the cord is sufficient to enable opposite sides of the loop to be wrapped around a pair of skis with the first tube tucked back between the opposite sides and spaced above the second tube in order to form a sling.

Abstract: A dispenser is intended to be used with a container of glue that enables pressurized outflow of the glue from an upstanding neck that is threaded to receive the dispenser. A cap threads upon the neck and has an annular top wall. A hollow snout of resilient material projects upward from the top wall and terminates in an opening that defines a valve seat. A guideway in the snout slidably accepts a rod on the upper end of which is a valve. Encircling the lower end portion of the rod is a ring so sized as to be seatable against the top wall of the cap. A plurality of resilient webs are circumferentially distributed in a normal plane and integrally extend between the ring and the rod with each of those webs generally defining a partial spiral and the webs together enabling longitudinal movement of the rod when the ring is seated against the top wall of the cap.

Abstract: The assembly includes a shelf bracket for constructing shelving from spaced elongated shelf boards that have a standard thickness. An elongated leg of rectangular cross section includes a longitudinal groove formed into one of its major surfaces. A pair of U-shaped clips each are in the form of a pair of plates joined by a flat bight with the widths of the plates being spaced apart for snug engagement with a marginal edge portion of a shelf board. The bight seats tightly in the groove and preferably has a thickness substantially equal to the depth of the groove. The clips are individually secured in respective different spaced portions of the groove with the bight seated therein.

Abstract: A valve mechanism for dispensing viscous, sticky materials from a container having a neck defining a discharge opening. The valve is formed by a tubular body threaded at one end for engaging the container neck. A normally closed spring biased valve in said body controls the discharge of material from said container. The valve body defines a spheroidal dispensing cavity opening through one end thereof for accessibly retaining for subsequent use an increment of material discharge from the container through the valve. In an alternative version, a ball valve is so seated as to preclude wedging of the material into the valve seat.
