Title: Positioning system for digital telephone networks
Inventor: DUFFETT-SMITH PETER JAMES
IPC: H04W64/00
Filed: 1998-10-21
Granted: 2005-08-16
Abstract: The invention relates to determining the position of a mobile receiver (4) in a digital telephone network positioning system. A first receiver (3) is at a known location and others are mobile. The method involves transmitting signals from a plurality of sources (1), the transmission signals having a format at least a portion of which has predetermined values or a portion of which is repeated. The time offset of the transmission signals received at each receiver (4, 5) from a transmission source (1) relative to a reference clock of each receiver is determined by generating a reference signal locked to the reference clock. The reference signal has a similar format to the transmission signals and includes a portion identical to the predetermined values or repeated portion of the received signal and compares the received transmission signal and the reference signal. The time delay between the respective signals received at the receivers (4, 5) is determined from their relative time offset, to thereby determine the position of the other receivers (4).

Title: Bale wrapping implement
Inventor: VIAUD JEAN
IPC: A01F15/07
Filed: 2000-04-27
Granted: 2005-07-26
Abstract: The present invention relates to a bale wrapping implement coupled for trailing a baler and constructed so as to minimize loads experienced by its frame during operation on uneven terrain. This is realized by constructing the wrapping implement so as to have a main frame including a first frame section having a forward end defined by a coupling, which allows the main frame to pivot vertically when coupled to the baler. A main support wheel, which is the only support for the wrapping implement that is in continuous ground contact, is mounted to a rear region of the first frame section, while an auxiliary support wheel is mounted to a second frame section carrying a bale-support structure, the auxiliary support wheel contacting the ground only when the second frame section is deflected downward by the weight of a bale discharged from the baler onto the bale-support structure.

Abstract: A medical device assembly and method provides an ultrasound transducer mounted onto a delivery member, such as the elongate body of a catheter shaft, without a support structure bridging between a separation area between the transducer and the shaft. Mounting flanges extend from either end of the transducer and are mounted at first and second locations along the catheter shaft such that the transducer is not in mechanical contact with the catheter shaft between those mounting locations to provide for air backing between the transducer and the catheter shaft so as to isolate ultrasound transmission radially away from the catheter shaft and toward the tissue surrounding the shaft. The transducer is substantially "airbacked" when mounted onto a delivery member in accordance with the present invention. In an overall tissue coupling system, a cylindrical ultrasound transducer is mounted onto a catheter shaft and enclosed within a balloon also provided on the catheter. The balloon is ideally adapted to engage a circumferential region of tissue where a pulmonary vein extends from an atrium such that the cylindrical ultrasound transducer is able to couple through the balloon inflation fluid and to the circumferential region of tissue surrounding the balloon for ablation.

Abstract: This invention concerns a method for the preparation of a suspoemulsion formulation, which can be easily produced on an industrial scale and which allows the reproducible and effective administration of one or more water- insoluble veterinary drugs through water distribution systems. The water- insoluble veterinary drug, in finely ground form, is dispersed in a water immiscible liquid, followed by homogenisation of this system into a water phase. To facilitate the preparation of a stable formulation, one or more stabilising agents such as emulsifiers, thickeners, anti-oxidants and anti- microbials can be used. The resulting suspoemulsion shows excellent long term storage stability and a good "in use" stability after dilution in a vessel and during all handling and transport in the water distribution system.
