Patent CA-2381301-C (CA)
Inventor: STAMIRES DENNIS
IPC: C01F7/448

Granted: 2009-01-20
Abstract: The present invention pertains to an improved process for the preparation of quasi-crystalline boehmite. In this improved process a quasi-crystalline boehmite precursor is aged at a pH below 7, preferably under hydrothermal conditions. It was found that when conducting the preparation processes for quasi-crystalline aluminas described in the prior art at a pH below 7 and under hydrothermal conditions instead of the high pH and thermal ageing used in the prior art, QCBs with higher crystallinity are obtained. In the process according to the invention additives may be added t o the quasi-crystalline boehmite precursor. This results in a high quality QCB with additives in a homogeneously dispersed state. Suitable additives are compounds containing elements selected from the group of rare earth metals, alkaline earth metals, transition metal s, actinides, silicon, gallium, boron, and phosphorus.

Patent CA-2391395-C (CA)

Granted: 2006-08-22
Abstract: A method and apparatus for compensating for systematic error a wavelength measure device, providing values for the wavelengths reflected from fiber Bragg gratings (FBGs) being used as sensors. The invention uses a high-precision temperature sensing and measuring circuit to measure the temperature of a reference FBG. The wavelength reflected by the reference FBG changes with temperature in a known way and the temperature of the reference FBG must be measured to know what wavelength is in fact being reflected. This wavelength is then provided to a dynamic compensator, which also receives the wavelength of light reflected from the sensor FBGs, and adjusts the wavelengths of the sensors FBGs using a correction based on the correction required to adjust the wavelength of the reference FBG so as to agree with the wavelength in fact reflected from the reference FBG. The circuit uses a reference resistor, unaffected by temperature, and a thermistor, and measures bothresistances using the same exact circuit components by switching either the thermistor or the reference resistor in to the same temperature sensing and measuring circuit.

Abstract: Methods and apparatus for statistical multiplexing in a dual pass encoding scheme are provided. A first pass encoder encodes alternate slices of anchor frames as I- slices and P- slices respectively in order to generate statistics fox both I and P frame encoding for the same anchor frame. A second pass encoder determines the encoding complexity estimates for a plurality of frames in a look-ahead pipeline and sums the encoding complexity estimates of selective frames in the look-ahead pipeline to determine the initial need parameter for a current fi~ame to be encoded. The second pass encoder computes a need parameter for encoding the current frame based on the initial need parameter. The need parameter is used by a statmux processor to determine the encoding bit rate for second pass encoding of the current frame.

Granted: 2008-10-14
Abstract: An interface circuit for converting a digital signal to an analog signal. The interface circuit includes a time response adjustment circuit, a modulator, and a filter. The time response adjustment circuit receives the digital signal and generates an adjusted signal. The modulator couples to the time response adjustment circuit, receives the adjusted signal, and generates a modulator signal. The filter couples to the modulator, receives the modulator signal, and generates the analog signal. The analog signal has a time response that is modified by the time response adjustment circuit. In an embodiment, the time response adjustment circuit includes a gain element, a delay element, and a summer. The gain element receives and scales the digital signal by a scaling factor. The delay element receives and delays the digital signal by a time delay. The summer couples to the gain element and the delay element, sums the scaled signal from the gain element and the delayed signal from the delay element to generate the adjusted signal.

Abstract: L'invention concerne un procédé et un générateur de gaz destinés à la production par distillation sèche de solides et gazéification de solides d'un gaz de combustion sensiblement exempt de substances volatiles de distillation sèche condensables qui pourraient produire des interférences lors de l'utilisation prévue du gaz, pour alimenter un moteur thermique, par exemple. Ce procédé consiste à maintenir des lits solides situés dans différentes zones de distillation sèche et de gazéification dans des conditions permettant de favoriser le craquage thermique de substances volatiles (goudron) condensables dans les régions chaudes desdites zones. Pour des conditions optimales, on sépare ces zones physiquement par des éléments internes situés dans une cuve à réaction unique et on effectue, éventuellement, une partie de la distillation sèche (pyrolyse) dans une autre cuve à réaction. Dans ce cas, les substances volatiles de pyrolyse sont fournies à contre-courant au lit de distillation sèche, récupérées au-dessus du lit puis envoyées dans le lit de braises de la zone de gazéification. Le craquage thermique des substances volatiles de pyrolyse est prolongé et intensifié de façon que ces substances volatiles soient amenées en contact étroit dans le lit de braises de la zone de gazéification à cocourant. Le lit de braises est guidé le long d'une voie de plus en plus étroite permettant de réguler le débit et le temps de résidence du lit de solides dans le procédé et le générateur.

Title: Large round baler with weighing arrangement
Inventor: VIAUD JEAN
IPC: G01G19/52
Filed: 2003-09-05
Granted: 2008-03-11
Abstract: A large round baler is provided With a weighing arrangement for the detection of the weight of a cylindrical bale. The weighing arrangement is arranged to detect the force that a cylindrical bale applies to a support element located in the baling chamber and movable relative to the bale for supporting substantially the entire weight of the bale during discharge of the bale from the baling chamber. So that a true weight reading is obtained, the side pressure exerted on the bale by the side walls is released before the weight measurement takes place. Additionally, an inclination sensor is provided for sending information to an evaluation arrangement which makes an adjustment in a sensed weight to account for any engagement of the bale with the sides of the baling chamber due to side-to- side inclination.

Granted: 2012-03-13
Abstract: A method of intermittently disabling the generation of an alarm signal by a plurality of interconnected adverse condition detectors during a temporary alarm locate period such that the adverse condition detector actually detecting the adverse condition can be identified. In an interconnected system of adverse condition detectors, all of the detectors generate an alarm signal when any of the detectors is sensing an adverse condition. When the test switch on any of the detectors not actually sensing the adverse condition is actuated, the alarm signal is inhibited on all of the detectors except the detector actually sensing the adverse condition. The alarm signal is inhibited for a majority of the alarm locate period and allowed to activate for only portions of the alarm locate period.

Abstract: The present invention relates to downhole apparatus and particularly but not exclusively, to multi-cycle circulating subs used during downhole drilling operations. Apparatus is provided comprising a piston (42) slidably mounted in a body (4) between positions in which at least one aperture (40) in the body is opened and closed. Movement of the piston (42) is controlled by a pin (86) secured to one of the body and a control member, and a control groove (52) in which a portion of the pin is received formed in the other of the body and control member. An arrangement of elements (32, 76) respectively connected to the control member and body is such that, as the control member moves axially, increasing lengths of said elements locate adjacent one another so as to provide resistance to relative rotation in at least one direction of the control member and body. The relative rotation is rotation which presses the control member against the control groove. The present invention thereby provides means by which the risk of damage to the control pin is reduced.
