Abstract:
A range of cores (28, 45) which each have a head (28A, 46 and 47) on which a dental prosthesis is to be mounted and a shank (29) which is adapted to be fitted in a standard socket (30) formed in an implant (24), wherein the angle of the head (28A, 46 and 47) of each core (28, 45) of the range, relative to its shank, (29) is different from the angle by which the head (28A, 46 and 47) of each of the other cores (28, 45) of the range is oriented relative to its respective shank (29), either in a plane which includes the axes of the head (28A, 46 and 47) and shank (29) or angularly about the axis of the shank (29), or both.
Abstract:
Embodiments of a method and system for acquiring a marine seismic survey are described. One method may include depositing on a seafloor a line of cable sections extending in a first direction. The line of cable sections may have a first end and a second end and may include a plurality of seismic wavefield receivers. The method may also include moving the line of cable sections by collecting cable sections from the second end of the line and depositing cable sections at the first end of the line so that the line of cable sections travels in the first direction. At least one source vessel may be used to provide acoustical waveforms while the line of cable sections is moving. The acoustical waveforms may be received by the plurality of seismic wavefield receivers in the line of cable sections so as to enable generation of a seismic survey.

Abstract:
A game ball assembly for use with a game ball is described comprising a net for receiving and holding the game ball, a handle adapted to be retained within a user's hand, a length adjuster having a body part and a relatively movable locking slide part defining with said body part two paths at opposite sides of the slide part, and an elongated substantially inelastic tether cord or rope secured between the handle and the net. The tether extends through one of the paths of the length adjuster, through the net and then through the other path of the length adjuster such that a free end of the tether is supported between the slide part and the body part of the length adjuster. This arrangement facilitates simple adjustment of the length of the tether.

Abstract:
An arrangement usable as a core for a dental prosthesis or as a transfer jig in forming a model of an alveolar arch with one or more implants (24), comprising a nut (36) which is for fitting in a hexagonal portion of a socket (30) in the implant (24), a ring (35) for fitting over the nut (36) and seating around the mouth of the socket (30), and a post (37) for screwing through the nut (36) and the ring (35) to the implant (24). The ring (35) also has a hexonal bore portion which receives part of the nut (36). Thus the ring (35) is located spatially and angularly relative to the implant (24) without being socketted therein. When a dental impression has been formed with a plurality of the rings (35) embedded therein, or when a sub-frame for a bridge has been made up on two or more such rings (35) on a model of the alveolar arch made from that impression, it is removed by first unscrewing the post (37) and withdrawing it and the nut (36). Thus the impression or bridge sub-frame is easily removed despite the probability that the axes of the implants (24) in the alveolar arch are not parallel.

Abstract:
A handle particularly for use with plastic grocery bags is disclosed. The bag is of the type having two side walls with openings near the top for carrying the bag. The elongate handle is substantially rigid and the ends of the handle have notches which receive edges of the side walls at the openings. The notches are shaped such that the handle will not accidentally separate from the bag when it is set down. In a preferred form, the handle is of thin plastic which is arcuate in transverse cross section and placed in the bag opening so that the convex side faces downwardly. An intermediate part of the handle can have two longitudinally-spaced openings to receive hanger hooks to facilitate carrying clothes in a clothes bag when traveling.

2100878 9212766 PCTABS00014 A game ball assembly (10) for use with a game ball (14) is described comprising a net (12) for receiving and holding the game ball (14), a handle (16) adapted to be retained within a user's hand, a length adjuster (18) having a body part and a relatively movable locking slide part defining with said body part two paths at opposite sides of the slide part, and an elongated substantially inelastic tether cord or rope (20) secured between the handle (16) and the net (12). The tether (20) extends through one of the paths of the length adjuster (18), through the net (12) and then through the other path of the length adjuster (18) such that a free end of the tether (20) is supported between the slide part and the body part of the length adjuster (18). This arrangement facilitates simple adjustment of the length of the tether (20).
