Patent CA-2260458-A1 (CA)
Inventor: RINGGENBERG PAUL D
IPC: E21B47/12
Filed: 1999-01-26
Abstract: A downhole telemetry system (10) for remote communication is disclosed. The system (10) includes a downhole transmitter (44) that radiates an electromagnetic signal (46) carrying information into the earth. The electromagnetic signal (46) is received by a subsea repeater (48) that processes and retransmits the information through the sea. A remote station (54) receives the information from the subsea repeater (48) and stores the information. A master station (70) periodically polls the remote station (54) to request the information using meteor burst trails (76) to reflect radio waves (80) between the master station (70) and the remote station (54). Following the request, the remote station (54) generates radio waves (80) carrying the information that are reflected off meteor burst trails (78) and received by the master station (54).

Filed: 1999-07-08
Abstract: A cooking grate for a grill, such as a barbecue grill, is comprised of a plurality of generally elongate rail members assembled in a nesting relationship to form a first and second cooking surface. The first cooking surface is formed by a generally flat surface on each of said rail members, said flat surfaces abutting to form a substantially smooth surface, with a plurality of elongate apertures therein through which juices produced by cooking food may flow. Each rail member has a gutter along its length which underlies approximately half of each of said apertures for catching a portion of the juices and diverting it from the heat source below.

IPC: C07H15/24
Filed: 1999-07-20
Abstract: Individual sweet glycosides are obtained from the stevia rebaudiana plant. A  mixture of sweet glycosides extracted from the stevia rebaudiana plant are processed to remove impurities by using two ion exchange columns. After removing the mixed sweet glycosides from the second column with methanol the solution is dried. Upon refluxing the dried solids in a methanol solution and then cooling the solution, Stevioside precipitates out. The filtrate is further concentrated and cooled to precipitate out Rebaudioside A. This Rebaudioside A can be further purified as can the previously obtained Stevioside.
Patent CA-2278576-A1 (CA)
Inventor: WELLS NICHOLAS DOMINIC
IPC: G10L19/16
Filed: 1998-01-27
Abstract: An auxiliary data signal is derived from a received compression encoded audio signal during decoding of the signal and communicated with the decoded audio signal for use in re-encoding the signal. The auxiliary data signal may be communicated integrally with the audio signal, for example in the least significant bits, or may follow a different path. The provision of the auxiliary data signal may enable more transparent decoding and re-coding processes to take place, by allowing the coding decision to match the coding decisions originally used; this can alleviate problems with quality reduction arising from cascaded decoding and re-coding processes.

Title: Constant temperature packaging system and phase change formulation
Inventor: MALACH TED J
IPC: C09K5/06
Filed: 2000-03-10
Abstract: A thermal packaging system using a single phase change material (PCM) part in liquid and part in solid form to confine the temperature of the product within a predetermined range. The temperature ranges are determined by the selection of PCM formulation. The phase change materials selected have high latent heats of fusion and maintain relatively constant temperatures as they change phase. This permits light weight packaging with the maintenance of temperatures in narrow, preselected ranges over extended periods of time. A phase change formulation that can be adjusted to freeze at temperatures from +40 °C to below -30 °C is disclosed, comprising butanediol, selected percentages of distilled water, and nucleating agents. The phase change occurs over a narrow temperature range making this an ideal temperature control media. Nucleating or other agents are included to narrow the temperature range over which the phase change occurs.

Title: Method and system for determining position of a cellular mobile terminal
Inventor: LUNDQVIST PATRIK
IPC: H04B7/26
Filed: 1998-09-11
Abstract: A method (500) and system (200) are disclosed by which a round-trip calculation is used to determine the distance between a mobile radio station (MS) (208) and a radio base station (BS) (BS0, BS1, BS2) using the apparent uplink and downlink signal propagation air-times (e.g., T-up and T-down). As such, no absolute time reference is required. The MS and BS report to a service node (203) in the mobile network (200) the local departure and arrival times (308, 328) of the uplink and downlink signals (212-215), and calculate the apparent air-times, T-up and T-down. The distance, D, between the MS and BS can be calculated as D = c(T-up + T-down)/2, where "c" equals the speed of light. The distances, D1, D2 and D3, to at least three base stations whose locations are known, can be used in a triangulation algorithm to determine the MS's position.
