Title: NMR well logging device with reduced ringing
Inventor: SUN BOQIN Q
IPC: G01V3/32
Filed: 2001-05-31
Abstract: A method for reducing ringing in nuclear magnetic resonance measurements includes inducing a static magnetic field in a sensitive volume to orient nuclear magnetic spins of nuclei in the sensitive volume. The nuclear spins are reoriented by a first selected angle. An amplitude of the static magnetic field is then adjusted to cause a first selected phase shift in a spin echo signal measured subsequently to the reorienting by the first angle. The spins are then reoriented by a second selected angle, and a first spin echo signal is detected. After a selected wait time, reorienting by the first selected angle is repeated. Adjusting the amplitude of the static magnetic field is then repeated to cause a second selected phase shift in a subsequently measured spin echo. The first and second selected phase shifts have a difference between them of an odd numbered multiple of 180 degrees. Reorienting by the second selected and detecting a second spin echo signal are then repeated. Finally, a difference between the first spin echo signal and the second spin echo signal is determined. In one embodiment, the measuring of the first and second spin echoes is repeated a selected number of times, and the difference is calculated between time corresponding ones of the first and second spin echoes. The amplitude of the static magnetic field may be adjusted by passing DC current through coil (304, see figure) wrapped around magnet (302). Various magnet arrangements are disclosed.

Title: Pressure Monitor Incorporating SAW Device
Inventor: FREAKES GRAHAM MICHAEL
IPC: G01L9/00
Filed: 2001-10-10
Abstract: A pressure monitoring device comprises a rigid base (2) which has secured thereto a lid (5) to define a hermetically sealed chamber (6). The lid (5) is of flexible metal material and the major surface (5A) of the lid forms a diaphragm which will deflect in response to changes in the pressure surrounding the monitor. A substrate (7) upon which a plurality of SAW devices are laid down is supported on a rigid frame (3A) of the base so that the central region thereof is unsupported between edges (11,12). A dimple (10) is formed in the lid (5) and presses on a central region of the substrate (7). Changes in pressure will accordingly cause distortion of the central region of the substrate. The end regions (8,9) of the substrate (7) carry further SAW devices so that, by analysing the changes in characteristics of all the SAW devices a temperature compensated indication of pressure change, together with an indication of absolute temperature, may be provided by interrogating the SAW devices. The base (2) and the lid (5) are preferably both of metal alloy and may be secured together by soldering. Antennae associated with the SAW devices may be laid down as tracks on the surface of the base (2).

Title: Flexing spanner
Inventor: HARTLEY BARRY PAUL
IPC: B25B13/28
Filed: 2002-01-12
Abstract: The invention is a general purpose spanner that can automatically adjust to fit various nut size ranges. The spanner consists of two nut gripping jaws 11 and 12-15, each mounted onto one of two parallel bars 1 and 2 which are in turn linked by a circular hoop 3 region. (Figure 3). The parallel bars act like a pair of tongs, and by flexing the nut gripping aperture between the two jaws accommodates ranges of nuts. The two nut gripping jaws have opposite nut gripping angles that match two opposite corners of nuts to be accommodated. A rocker section 13 of jaw 12-15, ensures a parallel nut gripping aperture. The other jaw (opposite nut grip jaw) 11 is able to extend and retract to accommodate varying nut widths via a sliding mechanism 4-10 on the corresponding parallel bar. This is kept proportional to the widening or narrowing of the nut gripping aperture by a slide regulator 10 positioned between the two parallel bars. A guiding and restraining brace 6 prevents the parallel bars from being over stretched and over squeezed, thus also acting to limit the jaws movement. Handle grips 16 may be mounted on the parallel bars.

Title: Optical rotary encoder with floating aperture piece
Inventor: SOAR STEVEN E
IPC: H03M1/10
Filed: 2003-06-03
Abstract: An encoder (30) includes a housing (50), a light source (52) coupled to the housing (50), and a light sensor (54) coupled to the housing (50) and positioned to receive a light beam from the light source (52). The encoder (30) also includes a wheel (44) having opaque and transmissive sections which may be positioned to pass though the light beam before it reaches the light sensor (54). The encoder (30) further includes a floating aperture piece (58), which defines at least one aperture. The aperture is positioned so that the light beam must pass through it before reaching the light sensor (54). The floating aperture piece (58) slidably engages the housing (50) while allowing a loose tolerance between a position of the wheel (44) and a position of the housing (50), thereby substantially eliminating a positioning error (FIGS. 3, 4) between the aperture (56) and the wheel (44). The aperture piece may slidably engage the housing by means of a key portion (70) or a spring (Fig 9, not shown). The aperture piece (58) is typically mounted on the same shaft (32) as the encoder wheel (44).

Title: Central determination gaming system
Inventor: WOLF BRYAN D
IPC: G07F17/32
Filed: 2004-05-06
Abstract: A central determination gaming system has one or more gaming terminals assisting a central controller, Fig 1 (not shown), in the generation of a game outcome, eg in stopping the reels of a slot machine in a specified arrangement. Upon a player initiating a game play (step 202) at one of the terminals, the processor within that terminal generates a random number (step 204) which is communicated to the central controller (step 206); the central controller associates the generated random number with an available game outcome selected from a pool or set of such outcomes (step 208) and then marks or flags this outcome as unavailable for subsequent selection (step 210). The selected outcome is communicated back to the requesting terminal (step 212) where it is displayed the player (step 216). It is stated that the advantages include random number generation at each terminal, not at a single central site, providing less security risk; existing probability-based terminals can continue to be used and give the player that appearance despite the central control effectively conferring certain definite awards across the network; outcomes remain unpredictable to the player, especially if the indexing of the available outcomes changes after each selection removes an outcome from the pool or set.
