Abstract: A process in which material comprising an aqueous liquid with dispersed particulate solids is transferred as a fluid to a deposition area, then allowed to stand and rigidify, and in which rigidification is improved whilst retaining the fluidity of the material during transfer, by combining with the material an effective rigidifying amount of aqueous solution of a water-soluble polymer. The process is particularly suitable for the treatment of the tailings underflow resulting from a mineral processing operation and the co-disposal of fine and coarse tailings fractions. In addition, liquor released during the rigidification step is of high clarity.

Title: Determination of leak and respiratory airflow
Inventor: BERTHON-JONES MICHAEL
IPC: G01M3/26
Filed: 1997-08-14
Granted: 2011-01-25
Abstract: Methods and apparatus for determining leak and respiratory airflow are disclosed. A pressure sensor (34) and a differential pressure sensor (32) have connection with a pneumotach (24) to derive instantaneous mask pressure and airflow respectively. A microcontroller (38) estimates a non-linear conductance of any leak path occurring at a mask (12) as being the low pass filtered instantaneous airflow divided by the low pass filtered square root of the instantaneous pressure. The instantaneous leak flow is then the conductance multiplied by the square root of the instantaneous pressure, and the respiratory airflow is calculated as being the instantaneous airflow minus the instantaneous leak flow. The time constants for the low pass filtering performed by the microcontroller (38) can be dynamically adjusted dependent upon sudden changes in the instantaneous leak flow.

Abstract: A bore hole rotary reamer (1) includes a body (2) having cutters (4) contained in respective recesses (3) formed in the body (2). Each cutter (4) is rotatably mounted by one or more respective spindles (5). A bearing region (10) is formed by an inner bearing surface (11) rotatable on an outer surface of the spindle (5). At least one annular seal (12) about the spindle (5) prevents ingress of contaminant to the bearing region (10). A circumferential void (13) is formed between the inner bearing surface (11) and the outer bearing surface of the spindle (5) adjacent the seal (12). At least one passageway (17) extends in an axial direction of the spindle (5) to the circumferential void (13) and a piston (19) movable in the passageway (17) in response to supply of pressure to an outer side (19a) of the piston (19) from the environment which surrounds the reamer (1). The piston (19) transfers pressure to fluid in the cylindrical passage (17) on an inner side of the piston (19) to supply pressure to the circumferential void (13) and thereby to the seal (12) that is substantially determined by the pressure of the environment surrounding the reamer (1).

Abstract: A method of forming a three-dimensional microstructure on a flat surface of a support, comprising the application of a first flat and uniform layer (2) of silicone on said surface of support (1) and the application on the first layer of silicone of a second three dimensionally microstructured layer (3) of silicone, said first layer and second layer of silicone become integrally connected to thus form a common three-dimensional microstructure ensuring anti-adhesive properties distributed regularly on the surface of the support, so that any flexible surface of substrate, in particular a surface of adhesive deposited on said layers of silicone will be microstructured by inverse replication of the three-dimensional microstructure formed by the two layers of silicone, where said layers of silicone are fixed by hardening by heating or by exposure to an ultraviolet or electronic radiation, or a combination thereof, applications thereof and films, notably self-adhesive films, such as those microstructured by said method.

Abstract: A safety guard 10 has a guard body 12 shaped such that it will fit over the yoke 18 of a power take off shaft. The yoke 18 includes a groove 24 formed in an outer surface near the end 22. Safety guard bearing 26 is mounted to groove 24. Safety guard bearing 26 also has a groove 28 formed in an outer surface. Two levers 30 are pivotally mounted to the safety guard body 12 by pivot pins that extend through apertures 36 in the levers 30. One end of levers 30 has a camming member that includes a lobe 38. Due to the relative position of the pivot aperture 36 and the lobe 38, the lobe 38 acts as an over centre cam. When lever 30 is in the locked position, lobe 38 extends into groove 28. Lever 30 also includes a locking tongue 46. When the lever 30 is moved to the locking position, locking tongue 46 also extends into groove 28 on safety guard bearing 26. Thus, locking tongue 46 provides a secondary locking mechanism to assist in maintaining the safety guard 10 on the safety guard bearing 26. Further, shoulder 48 abuts on the wall 52 of aperture 50 to thereby hold the lever in the locking position. Removal of the safety guard involves a simple hand-operated opening of levers 30, which then allows the guard to be slid away from the yoke of the power take off.

Abstract: A water shutoff and discharge control device for sprinklers comprises a water intake assembly mounted to a support seat and swung back-and-forth by a sprinkling control assembly wherein the water intake assembly has a tube with multiple bores drilled thereon for the mounting of a sealing strip equipped with multiple spray nozzles and water-sealing areas. Both end sections of the tube are disposed multiple control channels each connecting to the interior of the tube for the extension of a control shaft with a plug mounted thereto. Each plug having an inlet aperture and an abutment surface is corresponded to a water-sealing area of the sealing strip to reveal a movement space there-between, permitting the plug flushed by the water flow to climb upwards and, depending on the movement of the control shaft, to switch in position relative to the spray nozzle for easy control of water shutoff or discharge thereby.

Abstract: The present invention is directed to a method for determining the responsiveness of cancer to an epidermal growth factor receptor (EGFR) treatment. In a preferred embodiment, the presence of at least one variance in the kinase domain of the erbB 1 gene confers sensitivity to the tyrosine kinase inhibitor gefitinib. Thus, a diagnostic assay for these mutations will allow for the administration of gefitinib, erlotinib and other tyrosine kinase inhibitors to those patients most likely to respond to the drug.

Granted: 2010-08-17
Abstract: A hub-and-spoke communication arrangement is provided, in which the "hub" includes a server computer system. The "spokes" are other computers that act as message originators and/or destinations. All internal-to-external messages, and vice versa, are routed through the server computer system to reduce the number of proprietary connections needed between the internal and external entities. In addition, the server computer system provides protocol conversion, message payload conversion, encryption conversion, message broadcast, and/or message archival functionality, so that the "spoke" computers need not be concerned with providing such functionality on their own.

Abstract: A wireless communication system, which supports enhanced dedicated channel (E-DCH) data transmissions, includes a wireless transmit/receive unit (WTRU) (102), at least one Node-B (104) and a radio network controller (RNC) (106).  The WTRU includes a buffer (126), a data lifespan timer (124), a data retransmission counter (130), a hybrid-automatic repeat request (H-ARQ) process (128) and a controller (122). The timer establishes a lifespan for at least one data block stored in the buffer. If physical resources have not been allocated for a data block associated with a lifespan timer that is close to expiration, the WTRU sends an urgent channel allocation request. If physical resources have been allocated, the data block is prioritized for transmission with respect to other data blocks. The data block is discarded if the lifespan timer expires or if the WTRU receives feedback information indicating that the data block was successfully received by the Node-B.
