Title: Dart
Inventor: PAXMAN COLIN
IPC: F42B6/00
Filed: 1995-11-03
Abstract: A dart has two or more parts which are held together in normal use by magnetic means. This enables the parts to be separated easily for storage or replacement whilst maintaining a stable connection in use. In one embodiment a dart has a shaft (1) with threaded spigot (2) to engage a dart barrel (not shown) and a plain bore (3) with a magnet (4) in the base. A flight holder (5) has a spigot (9) with at least the end (10) being magnetically attractive to magnet (4). The arrangement avoids the need for precision matching or machinery of the spigot (9) and bore (3) to provide a stable fit. Removal is made easier due to lack of frictional binding. The two parts may be relatively rotatable. In an alternative arrangement, the parts are held in engagement through abutment surfaces using mutual repulsion of opposite magnetic poles. In a modification, the magnet may be in the nose for playing a magnetic darts game, and a nose part carrying a point may be attached to the magnet to play a conventional darts game. <IMAGE>

Title: Shape memory plastics article and method of processing same
Inventor: LLOYD JONATHAN ANTHONY
IPC: B29C48/09
Filed: 1998-06-05
Abstract: An article, for example a dental point, formed of a hydrophilic plastics material is capable of undergoing controlled radial expansion (d<SB>1</SB> to d<SB>2</SB>) upon hydration by aqueous media including body fluids without appreciable axial expansion. The hydrophilic plastics material is pre-stressed by application of pressure to its unhydrated form at a temperature in the range 100 to 160{C. It is then cooled to 40{C or less before release of the applied pressure. After cooling, the material may be machined to shape. Alternatively, pre-stressing can be carried out after shaping. Preferably, the pressure is applied by extruding the material through a die which may be maintained at the same temperature as that of the polymeric material. The article may also be used in engineering to develop gaskets for underwater use or as a tube or sleeve for sealing ruptured pipes; in electrical applications as a sleeve for sliding over electrical connectors; in medicine as a tube for sliding over limbs to immobilise broken bones and in vascular therapy as a tube or sleeve for sliding over arteries or for insertion into blood vessels or other body passages and cavities for opening up constrictions.

Title: Supervisory audio tone-signalling tone (SAT-ST) handling
Inventor: GUSTAFSON FREDRIK
IPC: H04B17/00
Filed: 1996-12-06
Abstract: Methods and systems allowing for the following two Supervisory Audio Tone-Signalling Tone (SAT-ST) qualifications: (1) when detecting an ST as being on, the signalling tone signal is accepted if the SAT strength value indicates that the SAT is on, in accordance with the IS-54-B standard; and (2) when detecting the ST as being on and a momentary or instantaneous SAT strength value indicates that the SAT is off, the signalling tone signal is not accepted at this stage. However, should the instantaneous SAT strength subsequently be detected as being on while the signalling tone is still on, the signalling tone signal is accepted, which is a deviation from the IS-54-B standard. In one embodiment, the measurements of the ST duration are not started until SAT and ST are both on.

Patent HU-H3734-A (HU)
Title: Tightening bolt mechanism
Inventor: SCHIEFER ERWIN
IPC: F16B13/00
Filed: 1992-05-15
Abstract: On the contact surfaces formed by the inner contour of the expanding sleeve (7) and the outer contour of the expansion of the shank (2), an expanding dowel has a friction-reducing coating (10). Said coating (10) produces a friction level between the expanding sleeve (7) and the expansion (3) of the shank (2) which is less than the friction level between the expanding sleeve (7) and the wall of the drilled hole. The friction difference thus produced causes a reliable subsequent expansion behaviour of the expanding dowel in the cracked tension zone. In addition to the coating (10), projections (11, 12) are arranged on the outside of the expanding sleeve (7), which projections (11, 12) are located one behind the other and maintain the contact with the wall of the drilled hole in the event of relatively large displacements of the expanding dowel, primarily in the cracked tension zone.
