Title: RAKE receiver which, based on channel conditions, adaptively provides the fine timing correction step of adjusting phase of over-sampling
Inventor: ALLPRESS STEPHEN
IPC: H04B1/711
Filed: 2009-09-25
Abstract: The invention concerns synchronization in a RAKE receiver. A signal received at a RAKE receiver is sampled and interpolated. Channel conditions such as SNR or/and dispersion are estimated, and based on the estimate a decision is made as to whether to perform a fine timing correction step. The fine timing correction step involves performing a tracking operation on the strongest RAKE finger so as to align the timing of the generation of samples with the timing of the signal and the RAKE finger. Preferably this is achieved through adjusting interpolation filter coefficients to provide an appropriate phase offset correction. The invention thus provides a timing correction mechanism which reduces timing errors without increasing the oversampling factor. Furthermore, the timing correction mechanism is adaptive in the sense that it is used only when required, thereby reducing unnecessary computing power.

Title: Trapping and gating positive and negative ions in a dual ion mobility spectrometer
Inventor: PENG HUA
IPC: G01N27/64
Filed: 2009-10-19
Abstract: A dual ion mobility spectrometer (Figure 1) comprises: an ion source 0; a first gate electrode 1, a third gate electrode 3, and a fifth gate electrode 5, all placed on one side of the ion source 0; and a second gate electrode 2, a fourth gate electrode 4, and a sixth gate electrode 6, all placed on the other side of the ion source 0; wherein during an ion storage mode of operation, the potential at the position on the tube axis corresponding to the first gate electrode 1 is higher than the corresponding potentials at the ion source 0 and the third gate electrode 3 so as to create a negative ion storage region, and the potential at the position on the tube axis corresponding to the second gate electrode 2 is lower than the corresponding potentials at the ion source 0 and the fourth gate electrode 4 so as to create a positive ion storage region. Ions are subsequently educed in a step-wise manner from each storage region into the respective drift regions by controlling the potentials of a combination of the electrodes.

Title: System and method for extracting power from fluid
Inventor: SHERRER GORDON DAVID
IPC: F03B3/18
Filed: 2008-05-05
Abstract: Smooth, preferably variable-sweep fluid collection device surfaces disposed into opposition with wind, river, surf, ocean or tidal currents generate enhanced velocity fluid flows at length driven into onboard work-extracting disc turbines at advantageous angles of attack. Keyed to shafts turning freely through optionally extendable volutes, disc turbines comprising a dense population of smooth, axially fixed or adjustably spaced discs conducting preferably laminar flow between adjacent elements develop significant torque through boundary layer adhesion and viscous shear-stress between fluid layers. Exhaust of disc turbine throughput into divergent channels drafting into external currents of initially higher than ambient velocity and lower pressure may reduce turbine discharge backpressure, rapidly clear system throughput, and allow normally disadvantageous drag to be utilized to develop greater work generation. Gainfully turning with, instead of at odds to natural or anthropogenic currents provided, disc turbines utilized as disclosed may provide unprecedented renewable energy from fluids in motion.

Title: Process for depositing a coating on the wall of a tube along one or more lines
IPC: B05C9/04
Filed: 1948-04-09
Abstract: A process for depositing a coating along at least a part of a line on the inner or outer surface of a tube but not along the whole length of this tube in which the tube is moved so as to contact the coating device consists in controlling this contact by at least two independent members which do not move with the tube and which touch, one after the other, at least one of the ends of the tube.  Referring to the drawings, the tube 6 is fed by rollers 7 and 8 along surfaces 2, 3, 4 and 5.  When (Fig. 4), both contacts 52 and 53 are broken no current flows to electromagnet 54 and hence coating device 60 being heavier than armature 57 rests on tube 6 and draws a line.  When, however, either contact 52 or 53 is made the <PICT:0655478/III/1> <PICT:0655478/III/2> <PICT:0655478/III/3> <PICT:0655478/III/4> armature lifts device 60 from the tube.  A similar device for coating the inner surface of a tube is shown in Fig. 5.  Here core 33 projects slightly beyond its windings when no current flows and so allows coating device 34 to contact the tube, but tends to enter completely into the windings when current flows and so rocks device 34 out of contact with the tube.  Fig. 6 shows how two lines spaced apart are drawn.  This arrangement works as for Fig. 5 but also closing of extra switch 70 discontinues the line drawing while opening of extra switch 71 recommences the line drawing.

Filed: 1945-04-25
Abstract: 590,963. Variable-speed gearing. HARTRIDGE, L. April 25. 1945, No. 10451. [Class 80 (ii)] Two pairs of V-belt connected expanding pulleys are arranged so that when the outer flanges of the input and output pulleys are moved by screw means in one direction, the inner flanges of the intermediate pulleys on a common shaft are moved in the same direction by belt tension. Increase in velocity ratio between output shaft 10 and input pulley 12 is caused by rotating nut 13, by chain 21 from sprocket 22 on shaft 23, which moves flange 4b towards flange 4a to increase the effective diameter of the pulley. A V-belt (not shown) connects pulleys 4, 5, increased belt tension moving flange 5b, sleeve 17 and flange 7b on intermediate shaft 16 in the same direction as flange 4b. The V-belt (not shown) connecting pulleys 6, 7, is maintained at constant tension by the similar directional movement of flange 6b effected by the nut 18 rotated by chain 26 from sprocket 25 on shaft 23. A decrease in ratio is caused by moving the flanges 4b, 5b, 6b, 7b, in the opposite direction. As nut 13 travels along thread 15 and nut 18 along its thread, alignment of chains 21, 26, is effected by shaft 23 being moved in the same direction through threaded portion 26 and housing 27. The pulleys 4, 5, 6, 7 have re-entrant hubs and radial intermeshing spokes to allow greater variation in effective diameter. Specification 464,331 is referred to in the Provisional Specification. Reference has been directed by the Comptroller to Specification 579,579.

IPC: F04F9/00
Abstract: 105,357. British Thomson - Houston Co., (General Electric Co.). March 10, 1916 High vacua in lamp bulbs, obtaining; vacuum obtained by condensation of steam &c.- Closed receptacles, such as bulbs for incandescent lamps, mercuryvapour rectifiers, X-ray tubes, and electron-discharge devices, are exhausted by means of a high-velocity stream of mercury vapour, flowing towards a condensing chamber through a tube, a portion of which communicates with the vessel to be exhausted, whereby the gas or vapour from the vessel becomes entrapped in the stream and carried along therewith. Mercury vapour from a bulb 3, heated preferably by an electric oil-immersed coil, passes upwards through a tube 1, jacketed at its upper portion by a second tube 2, having the connexion 4, with the vessel to be exhausted, and terminat. ing above in a condensing-chamber 5, the condensed mercury collecting in a groove 6, whence it returns 'by a tube to the heating-bulb. From the condensing-chamber the gas or vapour entrained by the mercury vapour is removed by an exhaust pump through a tube 8, and thus, if a suitable speed of the mercury vapour current is maintained, no backward flow of the gas is possible; to assist in securing this the tube 2 has an enlarged portion immediately above the extremity of the mercury-vapour tube. To avoid re-evaporation of mercury condensed within tube 2, a cooling-water-jacket 10 is provided. A higher vacuum may be obtained if a trap in the pipe communicating with the vessel to be exhausted is cooled by means of ice, freezing-mixture, or liquid air. The necessary stream of vapour may be derived from almost any liquid, for example, aniline, chloroform, or even, water may be used, according to the required degree of evacuation. Slight modifications may be made in the shapes of the essential tubes, condensing-chamber, and water jacket.
