Abstract: The present invention is directed to drying and heating processes and to an apparatus incorporating a pulse combustion device that can be used in a drying system or in a heating system. In general, the apparatus includes a pulse combustion device (12) for the combustion of a fuel to produce a pulsating flow of combustion products and an acoustic pressure wave. The pulse combustion device (12) has a combustion chamber (18) connected to at least one resonance tube (20). A resonance chamber (14) surrounds at least a portion of the pulse combustion device and includes a nozzle (34) downstream from the resonance tube (20). The nozzle (34) accelerates the combustion products flowing therethrough and creates a pulsating velocity head.

Filed: 1998-07-16
Abstract: Establishing a plurality of timing paths through a switching network that has a plurality of independent switching units with each switching unit switching one bit of each group of data from a given external data link through the switching network. Each switching unit establishes a path to each of a plurality of port timing units where each port timing unit controls a set of port units. Further, each port timing unit is responsive to timing information received on the plurality of timing paths to utilize the timing information to provide timing to its set of port units. Each port timing unit comprises timing difference detectors with each timing difference detector determining a difference in timing between an individual one of the plurality of timing paths and timing generated by the timing unit. Each of the port timing units is responsive to the difference in timing for adjusting the timing of the port timing unit to agree with the timing of the central timing unit. In addition each of the port timing units determines which of the timing paths have valid timing information and utilizes the valid timing information to calculate the difference to adjust the timing of the port timing unit. Also the determination of valid timing information is performed by the port timing unit doing a statistical analysis on the timing differences determined by the timing difference detectors.

IPC: G06T15/00
Filed: 1998-03-20
Abstract: There is described a three-dimensional imaging system for acquiring a succession of two-dimensional images of a target volume represented by an array of pixels and transforming the succession of two-dimensional images directly into a three-dimensional image.       Generally, the system comprises a scanner, a memory and a transformation means. The scanner scans the target volume using an angular scanning technique, and generates a succession of digitized two-dimensional images thereof representing cross sections of the to rget volume on a plurality of planes spaced around an axis of rotation of the scanner. The memory stores the succession of digitized two-dimensional images and a data set.      The data set comprises: (i) calibration parameters defining the geometric relationship between successive digitized two-dimensional images; and (ii) acquisition parameters defining the geometric and orientational relationship between successive digitized two-dimensional images. The transformation means receives the digitized two-dimensional image and the data set, and transforms the digitized two-dimensional images directly into a three-dimensional image of at least a portion of the target volume. The system is particularly suited to display a three-dimensional image from two-dimensional images which are acquired by a fan- or axially-acquired ultrasound image data.

Patent CA-2270501-A1 (CA)
Inventor: KELM ROLAND
IPC: G05D1/02
Filed: 1999-04-30
Abstract: A method of reducing the bending moment effect of wind gust loads acting on the wing of an aircraft involves adjusting the aerodynamic configuration of the wing so as to alter the distribution of lift generated by the wing during phases of flight in which critical wind gusts are expected to occur. Particularly, during climb and descent phases of flight below cruise altitude, the lift generated by outboard portions of the wings is reduced while the lift generated by inboard portions of the wings is increased. Thereby, the 1g basis load acting on the outboard portions of the wings is reduced, and consequently the total load applied to the outboard portions of the wings, resulting from the 1g basis load plus the additional wind gust load, is correspondingly reduced. This leads to a reduction of the bending moments effective on the wings, and of any rolling moment effective on the aircraft. The required adjustment of the lift distribution is preferably achieved by deflecting the ailerons of both wings symmetrically upward and/or deflecting the flaps of both wings symmetrically downward during climb and descent. The adjustment of the wing configuration is carried out dependent only on flight parameters such as the altitude, speed and gross weight, and does not require rapid sensing of the occurrence of a wind gust and rapid actuation of control surfaces to try to instantaneously counteract a wind gust as it occurs.

Title: Remedy for axillary osmidrosis containing adrenocorticosteriodal preparation
Inventor: YAMAMOTO KEIKO
IPC: A61K35/74
Filed: 1996-12-10
Abstract: A remedy for axillary osmidrosis which contains, per gram of the base, an effective amount of an adrenocorticosteroid and from 1 to 10 % by weight of an extract of lactic acid fermentation. This extract comprises metabolites of lactic acid bacteria and components constituting the cells thereof. Since the secretion of bad-smelling steroids per se causing axillary osmidrosis is inhibited thereby, the remetabolism and formation of these steroidal compounds by axillary osmidrosis bacteria are cleared away. In addition, there is little fear of the side effecfs of the adrenocorticosteroid employed therefor.
