  • Patent number: 7175811
    Abstract: Novel nanowell microarrays are disclosed in optical contact with polymer waveguides wherein evanescent field associated with lightwaves propagated in the waveguide excite target substances in the nanowells either by a common waveguide or by individual waveguides. Fluid samples are conveyed to the nanowells by means of microfluidics. The presence of the target substances in fluid samples is detected by sensing fluorescent radiation generated by fluorescent tag bound to the target substances. The fluorescent tags generate fluorescent radiation as a result of their excitation by the evanescent field. One or more PMT detectors or a CCD detector are located at the side of the waveguide opposite to the nanowells. Fluorescent radiation is detected due to its coupling with the waveguide or its emission through the waveguide.

  • Patent number: 7165373
    Abstract: A non-slip, nocoat drywall finishing system for finishing inside and outside corners of any angle, the finishing system being a pre-formed, continuously extruded trim piece comprising a semi-rigid member that can be relatively thick in the center and tapers laterally to a thin edge. An outer finishing layer of fibrous material that directly receives paint or texture. A pattern of protrusions, ridges, or grooves on the inner surface of the semi-rigid member to avoid the need for an inner material layer. To install one of the pieces, it is selected from stock and cut to length. A flat coat of mud is applied to both sides of an exterior or interior angle, and the trim piece is placed over the mud and smoothed into place. Once, the piece is in place, the edges are feathered once with a small amount of mud and a wide blade. At that point the corner is complete except for drying.

  • Patent number: 7114913
    Abstract: In a lubricant-cooled gas compressor (10) the temperature of separated lubricant returned to the air-side (11) is monitored by a thermostatically controlled restrictor valve (22) which minimises the flow of returned lubricant when temperature is low as on start up or when running on reduced load but increases the flow as the lubricant temperature increases. This will minimise he condensation of water from indrawn air when the temperature of the compressed air is too low to retain the water as vapour, so that the returned lubricant is contaminated with water which will damage the moving components of the air-end.

  • Patent number: 6991698
    Abstract: A method of making beams, clamps and other structures by curing a polymer containing a magnetostrictive material. A magnetostrictive material like TERFENOL-Dâ„¢ is placed in a polymer. This mixture is put onto a slide in a film. The mixture is cured by UV light (or other means) so that it cross-links. A second layer of polymer with no magnetostrictive material can be cured on top of the first layer. This leads to a beam structure which exhibits a bending moment in an applied magnetic field. By aligning the magnetostrictive particles before curing with a magnetic field, a beam or other structure can be produced with aligned particles. A mask can be used to selectively cure regions where the magnetostrictive particles have different alignments on the same layer. It is possible to build up multiple layer structures with layers of magnetostrictive particles aligned in different directions.

  • Patent number: 6986343
    Abstract: A mechanism for a gas powered gun where a tubular bolt 10 of a paintball gun communicates with a cylinder 16 through bores 17 when in a forward, firing position, allowing compressed gas from the cylinder to expel a paintball. A port 20 whereby the cylinder communicates with a source of compressed gas is occluded by the bolt 10 except when a circumferential recess 23 in the bolt is in register with the port 20. By this arrangement only gas stored in the cylinder 16 is used to fire a paintball and the source of compressed gas is not in communication with the cylinder except when the trigger is released and the bolt 10 is withdrawn.

  • Patent number: 6932857
    Abstract: A multi-stage collector of the type used to collect particles from industrial gas. The collector can contain multiple narrow and wide zones formed by a plurality of parallel corrugated plates. Contained in the narrow zones can be elongated electrodes with sharp leading and/or trailing edges. These electrodes can provide a non-uniform electric field near their sharp edges leading to corona discharge. The corona discharge causes particulate matter in the gas flow to become charged. The region in narrow zones away from the sharp edges of the electrodes resembles a parallel plate capacitor with relatively uniform electric field. In this region, particles can be collected on the plates and on the electrode. Wide regions can contain barrier filters (bag filters) with conductive surfaces. The collector can also be used to clean inlet gas in gasification plants and to collect re-usable materials from a gas stream.

  • Patent number: 6910603
    Abstract: A dispenser pump has a fixed spout (15) on an upper component (10) which is rotatable relative to a lower component (11) adapted to be fitted to a container (not shown). For transport and storage the spout (15) is rotated so that its inner opening is obturated by the distal end of an arm (13) of the lower component which circumferentially divides its discharge compartment (31). Simultaneously an air opening (22) of the upper component is obturated by the arm (13) which also circumferentially divides an annular air chamber (32) below the discharge compartment (31). The compartment (31) and air chamber (32) are separated by an annular barrier seal (23) in rubbing contact with the internal wall of the upper component (10). By this provision the danger of leakage is so much reduced that it is not necessary to provide a mechanical lock for the pump when the dispenser is closed.
