Title: Helical gear pump or motor
Inventor: WYNN BARRY
IPC: F04C2/08
Filed: 1995-07-07
Abstract: Hydraulic apparatus, for example a gear pump or motor, for low noise generation employs helical gears (8 and 10) retained within a casing. The contact ratio and the helical advance of the gear teeth (which may be approximately 2 and 1, respectively) are such as to substantially prevent back-flow of hydraulic fluid from the outlet side to the inlet side. In the case of a gear pump, a pressure relief recess (70 or 74) and a fluid feed recess (72 or 76) can communicate with the spaces between the teeth in the meshing zone at each end of the gears, the recesses being so shaped and positioned as to avoid communication with each other by way of said spaces, and the disposition of said recesses at one end of the gears relative to those at the other end thereof being staggered by an amount corresponding to the helical advance. Each pressure relief recess is a slot having a basic end surface (78 or 82) beyond which there extends a subsidiary slot or "nose" (80 or 84), and each fluid feed recess is a slot interconnecting the bearings for the shafts carrying the gears. In the case of a reversible gear motor, respective pressure relief recesses communicate with both ports of the motor at each end of the gears.

Title: Elongate ostomy filter and housing
Inventor: STEER GRAHAM EMERY
IPC: A61F5/441
Filed: 1997-09-18
Abstract: An ostomy filter comprises a filter housing (24) having a cylindrical bore (28) within which is received a cylindrical filter element (36). The filter element (36) has an axial length greater than its radius, and is slid longitudinally into the bore (28). A user can select a filter element to use having appropriate flow rate characteristics to suit his or her needs. The filter may be a discrete filter mounted on the pouch wall, or it may be incorporated into a stomal aperture coupling member (16) for the pouch. In one form, the filter element (36) can be replaced by inserting a new filter element through the outer end (30) of the bore, to displace the previous filter element and eject it through the inner end (32) of the bore into the pouch.

Title: Calculating wavefront travel time in seismic velocity models
Inventor: STANKOVIC GORAN MILAN
IPC: G01V1/30
Filed: 1997-10-06
Abstract: An array of output image points 16 is distributed over a velocity model of a subsurface region of interest. A fan of rays R is shot from each of a plurality of acoustic source points S along the surface, the angular separation between the rays being equal to n/n, where n is the number of rays. A family of travel time wavefronts (T, Fig.2) is erected at selected time intervals, #t, along the ray trajectories. The resulting wavefront map is superimposed over the array of output image points. Sub-arrays of output image points will lie within discrete travel time cells, the widths of which are defined by the separation between adjacent raypaths and the heights of which are defined by the wavefront separation distance. Ray segments, wavefront segments and output image points are identified by a velocity layer index. A velocity interface, that may cut across a travel time cell, divides the cell into two parts, each having a different layer index. The travel time to be assigned to a selected output image point is determined by projection from a nearby wavefront segment that has the same layer index as that of the output image point.

Title: Ion detectors for mass spectrometers
Inventor: KOSTER CLAUS
IPC: H01J49/40
Filed: 1997-10-28
Abstract: A detector for a time-of-flight mass spectrometer with high mass resolution for large masses (in the range of about ten thousand to several hundred thousand atomic mass units), comprises a convertor 2 for the conversion of large ions into smaller ions, which can then be detected with standard ion detectors for ions of smaller and average masses. The converter consists of a thin multichannel plate 2, such as is normally used for secondary-electron multiplication. However, in contrast to secondary-electron multiplication operation, it is operated at reversed polarity in order to produce large numbers of low-weight positive ions by a self-contained amplification process engaging secondary electrons accelerated in backward direction. These ions are detected by at least one further multichannel plate 3,4 in association with a collector 5 or scintillator (8). This device and operating method leads to a reduction in signal width and offer extremely high sensitivity for large ions.

Title: Electricity storage/discharge device with low internal resistance current collector structure
Inventor: YANG TAI HER
IPC: H01G4/30
Filed: 1998-01-20
Abstract: An electricity storage/discharge device has one or more electrode plates P101, P102, which each have a plurality of current collecting terminals C101, C102, C201, C202 for connection to input or output current circuits, in order to reduce the internal resistance of the device. The electrode plates can be in the form of a variety of geometrical shapes and arrangements (figs 3-116), but in each case a number of through-holes are provided in the electrode plates. Solid or hollow conducting rods B101, B102, B201, B202 then pass through some of the through-holes in order to connect the electrode plates in the desired relationship. In some embodiments, the through-holes are located on outer extended pieces of the electrode plates, in an asymmetric fashion, so that the orientation of the plates can be varied with respect to one another - for instance P101 and P102. This may allow certain conducting rods to connect only to certain plates. Thus the electrode plates can be connected in parallel, in series, or in a mixture of both. Figures 117-130 show an alternative electrode connection system.

Title: Detecting underground objects
Inventor: LEWIS ANDREW BIGGERSTAFF
IPC: E21B47/022
Filed: 1998-06-15
Abstract: A monitoring device 100 defines a boundary for movement of an underground object such as a boring tools 30. The underground object generates a magnetic field which is detected by the monitoring device. The monitoring device then determines the position of the underground object relative to itself, and hence to the boundary. The movement of the underground object can then be controlled so that it does not cross the boundary. The monitoring device may therefore define a protection zone 101 so that a buried object such as a cable 104 within that protection zone will not be contacted by the moveable underground object.

Title: Scanner for determining product size and/or shape using distance transducers
Inventor: WHITEHOUSE JOHN ARTHUR
IPC: B26D7/30
Filed: 1999-03-15
Abstract: A system for determining the size and/or shape of a succession of products 12 (eg logs of food) moving across the gap between conveyors 10, 18 comprises a ring mounting one or more distance transducers 36-42. The ring is disposed perpendicular to the direction of product movement such that each product passes through its central region, and is rotatable in a continuous or oscillatory manner such that the transducers scan the surface of the product as it passes. The underside of flexible products is assumed to match the premeasured surface of the conveyor, allowing top scanning only when there is no conveyor gap. The signals generated by the transducers are fed into a computer 48 along with speed and density data, and used to compute the product cross section, volume and weight. This data may be used to control later processing of the product (eg cutting into pieces, see Fig. 3).

Filed: 1995-03-27
Abstract: The invention relates to indicating progress toward or away from selection of a menu option from a dwell selectable menu and to interactive displays and interactive display methods for use by persons temporarily or permanently lacking normal motor capabilities. A particular dwell selectable region is at least partially delimited with respect to a display area. A movement related signal responsive to user movement is received, intersecting the particular region. The duration of dwell time is indicated, preferably by continuously brightening the particular region e.g. 3103 or an indicator e.g. 3203 associated therewith, while the user dwells on the particular region. Selection is preferably indicated by changing the hue of the particular region. The duration of the dwell period required for selection or a region may vary with the directness of the path taken to that region.
