Patent CA-2076006-A1 (CA)
Inventor: DENT PAUL W
IPC: H04W88/00
Filed: 1991-12-17
Abstract: Subtractive CDMA demodulation optimally decodes a coded information signal embedded in many other overlapping signals making up a received, composite signal. A radio receiver correlates a unique code corresponding to the desired signal to be decoded with the composite signal. As a result, subsequent correlations are performed with greater accuracy.      Subtractive CDMA demodulation is enhance by decoding the composite signal in the order of the strongest to weakest signal strength. Interference caused by the presence of the strongest information signal and the composite signal during the decoding of weaker signals is removed. The individual information signals are assigned a unique block error correction code (44) which is correlated with the composite signal using Fast Walsh transforms. Correlated signals are recoded using inverted Fast Walsh transforms (46) and removed from the composite signal.

Title: Process for recovering natural gas in the form of a normally liquid carbon containing compound
Inventor: VAN DIJK CHRISTIAAN P
IPC: C10G3/00
Filed: 1991-04-09
Abstract: This invention comprises a method for converting natural gas to a normally liquid carbon containing compound, such as methanol and/or dimethyl ether and/or to gasoline grade liquid hydrocarbons and/or olefins. The method of this invention elininates the need for steam reforming and/or adiabatic reforming with essentially pure oxygen of the natural gas to a synthesis gas. In accordance with the process of this invention, a synthesis gas may be produced at an op-erating pressure suitable for conversion thereof to methanol and/or dimethyl ether without the need for synthesis gas recompression. Fur-ther, the vent or bleed gas from the overheads after conversion to the crude product methanol/DME and/or its conversion to gasoline grade liquid hydrocarbons, generally has a BTU capacity required to serve as a fuel gas for supplying the energy needed for operation of the gas compression equipment requirements by which the process of this invention may be practiced. Accordingly, the capital and operat-ing cost associated with the production of methanol, DME and gaso-line from natural gas is significantly reduced by the method of this in-vention and renders it economically feasible for natural gas recovery processing at remote locations.

Title: Use of surface-active ester
Inventor: MUELLER HEINZ
IPC: C09K23/00
Filed: 1991-07-29
Abstract: Described is the use of surface-active salts of internally sulphonated esters, in which most of the sulphur is organically bound, made from at least once olefinically unsaturated carboxylic acids with at least 8 C-atoms and lower monohydric and/or polyhydric alcohols (ester sulphonate salts) as environmentally compatible emulsifiers of the water-in-oil type or oil-in-water type in fluid, pumpable bore-flushing agents or other drilling fluids which have, in addition to an aqueous phase, a closed or disperse oil phase and are suitable for the non-polluting exploitation of natural deposits of e.g. oil or gas.

Title: Pressure transmitter with stress isolation depression
Inventor: DEAN MICHAEL J
IPC: G01L9/00
Filed: 1991-11-20
Abstract: ABSTRACT OF THE DISCLOSURE A  pressure  transmitter  (10)  has  a  pressure transducer (12)  in a transmitter housing  (14).   The transmitter housing (14) includes a groove or a notch (20) defining a flexure closely proximate a housing outer rim (24).  The outer rim (24) receives a large clamping force from a flange (16) and is deflectable about the flexure for reducing transmission of axial and radial components of the clamping force from the housing outer rim (24) to the transducer (12), which forces can cause distortions to the pressure transducer (12).  Unevenly distributed  clamping  forces  caused  by  differential thermal expansion of the flange (16), bolts (26) and housing (14), are isolated from the transducer (12), thereby  reducing   measurement   errors.     Further, transmission  of  hysteretic  radial  forces  from  the transmitter housing (14) to the transducer (12) caused by friction when the flange (16) slides across the pressure transmitter housing (14), each having different thermal coefficients of expansion,  is also reduced.   Several types of pressure transducers (12) including capacitive cell transducers can be in the transmitter housing (14) for providing a pressure output indicative of line  and differential pressure.

Inventor: BODNARAS GEORGE
IPC: B01F3/04
Filed: 1991-11-25
Abstract: A method and apparatus for gas particle formation in liquid media, and its application to gas particle formation in a liquid/slurry in mineral beneficiation apparatus is disclosed. A gas particle formation apparatus comprises an adjustable hollow stem housed within a liquid chamber having a liquid inlet provided in the wall of the casing thereof. The stem is provided with an outwardly flared frusto-conical surface having a circumferential edge defining an annular lip on a head of the adjustable stem.      A portion of the surface is adapted to form a thin layer of gas thereon. The adjustable stem is slidably mounted in the casing with the surface of the head received in a circular aperture forming a liquid outlet in the casing, so that an adjustable annular gap is formed between the surface and a convex annular lip of the circular aperture.      Gas is delivered through distribution outlets covered by a self-sealing resilient spreader onto the surface portion of the head. In use, both liquid and gas are forced through the gap and as the gas layer escapes from the lip it is broken into gas particles by shear forces. A mineral beneficiation apparatus incorporating the gas particle formation apparatus is also described.

Title: Systems for conducting multiple analytical procedures using a central processing hub
Inventor: KELSO DAVID M
IPC: G01N35/00
Filed: 1992-12-18
Abstract: Systems for conducting analytical procedures include multi-ple work stations (22 to 36) that are each individually accessible through a common processing hub (100). A shuttle mechanism op-erates within the common processing hub (100) for conveying mate-rials to and from the work stations (22 to 36) through their associat-ed hub accesses. The common hub (100) creates a compact operat-ing zone in which access to the processing stations (22 to 36) can be arranged at different arcuate positions, as well as vertically stacked one above the other, thereby providing a processing module with a relatively small "footprint". The systems are capable of sequentially transporting a number of test carriers (12) in nonlinear, discontinu-ous paths among the various processing stations (22 to 36) to there-by perform different precribed processing tasks upon different car-riers (12) at the same time.

Title: Apparatus for and Method of Synchronizing a Clock Signal
Inventor: LAROSA CHRISTOPHER P
IPC: H04L7/00
Filed: 1993-01-21
Abstract: The present disclosure includes a discussion of a method of synchronizing a sampling clock signal to a received data signal (131). The clock recovery circuit (127) generates several clock signals (339 341, 343, 345) at the symbol rate, with each clock signal having a unique phase. To permit fast initial acquisition, the set of clock signals includes a pair of clocks which differ in phase by one-half of a symbol interval. Additionally, the clock recovery circuitry (127) generates error signals (347 349, 351 353) representing the difference between the phase of the received data signal and the phase of each clock signal. The error signals (347, 349, 351, 353) are processed over multiple symbol times to determine the optimal sampling phase. The clock recovery circuit (127) then adjusts or maintains the phase of the symbol clock (139) to provide the optimal sampling phase.

Filed: 1993-10-04
Abstract: An improved process for recovering one or more condensable compounds from an inert gas-condensable compound vapor mixture is provided. The inert gas-condensable compound vapor mixture is flowed through a first bed of solid adsorbent whereby the condensable compounds are removed from the mixture and a residue gas stream comprised of substantially condensable compound-free inert gas is produced and disposed of, e.g., vented to the atmosphere. A second bed of solid adsorbent is evacuated by vacuum pumping using a cooled liquid seal vacuum pump. As the resulting inert gas-condensable compound vapor mixture is contacted with the cooled seal liquid of the liquid seal vacuum pump, a major portion of the condensable compounds are condensed. The condensed compounds are recovered and a portion thereof are cooled and recycled as cooled seal liquid for the vacuum pump.
