Title: Sensing device and method for measuring emission time delay during irradiation of targeted samples
Inventor: DANIELSON SHELDON J D
IPC: G01N21/64
Filed: 1999-12-02
Granted: 2011-09-13
Abstract: An apparatus (10) for measuring emission time delay during irradiation of a sample (32). A mechanism (14) generates first and second digital input signals (16, 26) of known frequencies with a known phase relationship, and a device (20, 28) then converts the first and second digital input signals (16, 26) to analog sinusoidal signals. A radiation source (22) is modulated at a specific frequency and irradiates the sample (32) and generates a sample emission (34).  A device (36) detects the sample emission (34) and produces a first output signal (38) having a phase shift relative to the phase of the first input signal (16), and a mechanism (48, 50) converts the first and second analog output signals (38, 46) to digital signals. A mixer (52) receives the output signals (38, 46) and compares the signal phase to produce a signal (54) indicative of the change in phase. A feedback arrangement (56, 58) alters the phase of the second input signal (26) based on the mixer signal (54) to place the first and second output signals (38, 46) in quadrature.

Title: A combustion chamber
Inventor: VARNEY BRIAN ANTHONY
IPC: F23M20/00
Filed: 2001-07-30
Granted: 2009-11-17
Abstract: A three stage lean burn combustion chamber (28) comprises a primary combustion zone (36), a secondary combustion zone (40) and a tertiary combustion zone (44). Each of the combustion zones (36,40,44) is supplied with premixed fuel and air by respective fuel and air mixing ducts (76,78,80,92). Secondary fuel injectors (106) and two secondary fuel manifolds (105A, 105B) supply fuel into different circumferential sectors, halves, of the secondary fuel and air mixing duct (80). The secondary fuel manifolds (105A, 105B) have secondary fuel valves (107A,107B) which supply a greater proportion of fuel to the secondary fuel manifold (105A) than the secondary fuel manifold (105B) so that there is circumferential biasing of fuel in the secondary combustion zone (40). This circumferential biasing of fuel in the secondary combustion zone (40) reduces the generation of harmful pressure oscillations in the combustion chamber (28). Alternatively the biasing of the fuel may be in the primary or tertiary combustion zones (36,44).

Abstract: An apparatus and method for the completion of wells through a production tube includes a tool body having cement flow ports and pressure displaced port closure elements. A perforated mandrel tube concentrically aligned within the production tube is secured to said tool body at its upper end. Concentrically within the mandrel tube is a dart transport tube. The dart transport tube is releasably secured to the tool body by a set of locking dogs. A first dart plug is placed in the production tubing bore at the well surface to be pumped or allowed to gravitate onto a closure seat in the lower end of the of the transport tube. This seat closure allows the production tubing to be pressurized for setting well annulus packers and opening of a cement port closure sleeve. After the production tube has been set by cement pumped down the production tubing bore and through the cement flow port, a second dart plug is positioned atop the cement column in the production tube. A pumped column of water or other well working fluid sweeps most of the production tube cement column into the well annulus and lower end of the transport tube. The second dart plug lands against an upper bore seat in the transport tube to enable another pressure increase in the production tube fluid column. This next pressure increase shifts a sleeve piston that closes the cement flow ports and releases the transport tube locking dogs. With the locking dogs released, the transport tube falls to the end of the perforated mandrel and opens the mandrel perforations to formation fluid flow from the screens into the production tube bore. Residual cement remaining in the tube bore is all displaced into the transport tube and removed from the production flow path without drilling.

IPC: B07C3/14
Filed: 2000-08-08
Granted: 2008-01-29
Abstract: The invention relates to sorting items of mail in a plurality of sorting passes. In order not to have to read the address in each sorting pass and also not to have to print any machine-readable identification code on each item of mail, features characteristic of the items of mail are additionally determined during the first sorting pass and are stored together with distribution codes determined in the reading process.  During the subsequent sorting passes only the characteristic features of the items of mail are measured and compared with the stored features. In the event of agreement, the item of mail is assigned the associated distribution code. A particular feed regime with defined orders ensures that in each case only n items of mail have to be compared, where n = maximum multiple delivery rate to be expected.

Abstract: A swivel mount for a board binding of the present invention includes a base mountable to an upper surface of a board, and a swivel plate rotatably mounted on the base for relative swivelling rotation of the swivel plate relative to the base between a ride position and forward-walking positions. When the swivel plate is in the ride position the binding is oriented generally perpendicularly to a longitudinal axis of the board. When the swivel plate is in the forward-walking positions, the binding is oriented to point a user's forward foot in the binding toward a front end of the board so as to generally form an acute angle between the binding and the longitudinal axis of the board. A rotational resistance device cooperates between the swivel plate and the base for increasing rotational resistance above that of free-floating rotation but without locking of the swivel plate in a preset locking position when swivelling the swivel plate through the radial arc of the forward-walking positions. A ride position latch releasably locks the swivel plate in the ride position relative to the base upon rotational urging by the user's forward foot so as to return the swivel plate from the forward-walking position to the ride position. An actuator releases the ride position latch when actuated by a force applied in a first direction urging the swivel plate to swivel from said ride position to the forward-walking positions.
