Title: Dual satellite navigation method and system
Inventor: AMES WILLIAM G
IPC: G01S13/87
Filed: 1990-11-30
Abstract: A method and system for determining the position of an object using a fixed station and a plurality of earth orbit satellites whose positions are known. Separate periodic signals are transmitted from the fixed station via first and second satellites to the object whose postion is to be determined. The phase offset in periodic characteristics of the periodic signals as received from the first and second satellites is measured at the object. The phase offset corresponds to a relative time difference in propagation of the signals traveling two different paths to the object. The object transmits via the first satellite a return signal indicative of the measured relative time difference. This return signal is activated some time in the future according to the object local time, which is slaved to receipt of the periodic signal sent through the first satellite. This future time is the start of the particular time period as decided by the fixed station's schedule. At the fixed station, an instantaneous round trip delay, determined by the time offset of the current transmission clock time relative to the receive clock time of reception of the return signal, along with the measured relative time difference sent back on the return signal, is used to calculate the distances between the first and second satellites to the object. From these distances the position of the object is calculated.

Title: Process for Preparation of Bacterial Agricultural Products
Inventor: KOSANKE JOHN W
IPC: A01N63/20
Filed: 1991-11-08
Abstract: A process for producing a dried bacterial agricultural product having superior viability initially involves culturing (fermenting) a species of microorganism in a growth medium to form a culture. The culture containing the microorganism plus the growth medium is then mixed with a carrier. The resulting mixture is incubated for at least one day to increase the microorganism count in the mixture. The mixture is then air dried slowly for at least about one day so the moisture level in the microorganisms is gradually reduced to form the dried composition. The process may further include steps of milling and then coating seeds with the composition. An inoculant composition according to the invention, which may be made by the foregoing process, consists essentially of a clay carrier and at least 10 9 viable bacterial per gram of the composition. Compositions containing biocidal microbes which combat insects, fungi or the like, and other useful microbes, such as growth promoting bacteria, may also be prepared.

Patent CA-2083954-A1 (CA)
Inventor: TATTERSALL DEREK L JR
IPC: H03F1/32
Filed: 1992-03-17
Abstract: Briefly described the present invention is a feed forward amplifier network (200) employing a frequency swept pilot tone signal in order to reduce the distortion generated by the network's power amplifier (202).  A frequency swept pilot tone, generated for example by a variable frequency oscillator (213), is injected into the input path of the power amplifier's (202) input signal. Thereafter, distortion cancellation is employed to generate an amplifier output signal, substantially free of both pilot tone and the distortion signals generated by the power amplifier (202).  The amplified output signal is then detected by a detector (215) which is phase locked to the variable frequency oscillator (213) in order to ascertain the average pilot tone energy remaining within the am-plified output signal.  In response to a detection, various amplifier network characteristics are adjusted in order to reduce the amount of pilot tone at the amplifier network output (217).

Filed: 1991-10-17
Abstract: A method for measuring a time delay between a controller (302) and a plurality of base sites (306) in a simulcast system (300). The method begins with the controller (302) transmitting a first signal to one of the plurality base sites (306A) and transmitting a second signal at substantially the same time to a delay monitor (316) that receives the second signal and a third signal from a selected base site (306A). The delay monitor (316) transmits the time between the transmission and reception of the first signal to the controller (302) whichprograms the base sites (306) to delay transmissions of the RF signals in response to the measured delay.

Title: Speed estimation
Inventor: CHIA SI T S
IPC: G01S11/02
Filed: 1991-07-25
Abstract: A system and method of speed estimation for a cellular radio network comprises a number of speed estimation units (14-20).   Each unit comprises an averaging window (24) of a different duration, a buffer store (26) and variationcalculator (28).  The duration of each window is equivalent to the time taken by a mobile unit to traverse a distance of 20 wavelengths of the received signal at aparticular speed. An incoming signal is applied to the units. The duration of the window determines the significance of the fast fade components in the signal which is related to mobile unit speed. When the average of a window is substantially constant, the speed corresponding to that window can be assumed to be achieved or exceeded. Decision logic (30) is arranged to poll the outputs of the variation calculators to derive a speed estimation indication.

Abstract: Sonde parodontale à pression constante (1) composée d'un élément d'exploration (3) et reliée à un manche (2) par une charnière flexible (10). Un élément de soutènement (15) s'étend du manche adjacent à l'extrémité de la sonde (6) mais non contigu à celle-ci, de façon qu'il existe un espace (17) entre l'élément d'exploration (3) et l'élément de soutènement (15). Lorsque l'élément d'exploration (3) est introduit dans une poche entre la dent et la gencive (10), le degré de résistance fait en sorte que l'élément d'exploration (3) se déplace autour de la charnière flexible (10), comblant ainsi l'espace entre l'élément d'exploration (3) et l'élément de soutènement (15). Lorsque l'élément d'exploration (3) est mis en contact avec l'élément de soutènement (15), une pression constante à l'insertion est obtenue et une lecture est faite afin de déterminer la profondeur de la poche. L'utilisation d'une telle sonde parodontale à pression constante (1) permet de s'assurer que la lecture est faite à une pression fixe; on évite ainsi de blesser la gencive et les lectures sont précises.

Title: Microbial process for reduction of petroleum viscosity
Inventor: MONTICELLO DANIEL J
IPC: C12N1/20
Filed: 1991-12-05
Abstract: A method for reducing the viscosity of a liquid which contains sulfur heterocycles, in sufficient relative abundance for the physicochemical properties of these molecules to contribute significantly to the viscosity of the liquid. Viscosity is reduced by contacting the liquid with an effective amount of a biocatalytic agent capable of selectively cleaving carbon-sulfur bonds in sulfur heterocycles, thereby converting these molecules into products which no longer confer high viscosity. Biocatalysis is particularly suitable for reducing the viscosity of organic sulfur-containing petroleum liquids, including crude oils and fractions thereof, because the biocatalytic agent employed does not appreciably attack carbon-carbon bonds. Thus, biocatalytic reduction of viscosity does not significantly diminish the fuel value of petroleum liquids.
