Title: Detecting particles and changes in particle size in a suspension
Inventor: GREGORY JOHN
IPC: G01N33/18
Filed: 1983-11-02
Abstract: An apparatus for detecting particles and changes in particle size, for example as a result of flocculation, in a suspension comprises means 6 for directing a beam of light at the suspension, a detector 7 for detecting light emerging from the suspension and producing an output signal in response thereto, and means 8 for generating from the output signal of the detector 7 a signal representing the power of the fluctuating component of the said output signal of the detector 7 or a function of that power.

Patent GB-2195851-A (GB)
Title: Direction finding
Inventor: WADDOUP WILLIAM DAVID
IPC: G01S3/14
Filed: 1984-07-20
Abstract: A linearly polarised far-field signal incident on a cusp reflector (5) gives rise to a linearly polarised signal at its focus whose plane of polarisation depends on the azimuthal angle on arrival ( phi ) of the far-field signal. Placing a polarimeter (7,8,9) at the cusp reflector focus enables the plane of polarisation to be determined. This, combined with a coarse amplitude comparison measurement to indicate the quadrant in which the azimuthal angle of arrival lies, enables an accurate azimuthal angle of arrival to be determined. Placing a linearly polarising screen (6) around the cusp reflector ensures that the otherwise arbitrary polarisation of most signals becomes linear before encountering the reflector. <IMAGE>

Patent GB-2150590-A (GB)
Title: Method and plant for reducing oxidic material
Inventor: SANTEN SVEN
IPC: C10J3/08
Filed: 1984-11-05
Abstract: The invention relates to a method and a plant for reducing oxidic material. A reduction gas (18) is produced containing mainly carbon monoxide and hydrogen from carbonaceous or hydrocarbon- containing material by means of thermal energy from at least one plasma generator (10) in a separate gas-generating shaft (11). The reduction gas thus produced, after optional sulphur separation (22) and after temperature adjustment, is conducted to a reduction shaft (1) containing the oxidic material. The partially spent reduction gas (4) withdrawn from the shaft is freed from water and dust-like particles (5), after which a part-flow of the return-gas is returned to the process and a small part-flow of the return gas is removed from the system (at 6) for pressure regulation. A small part-flow of said partially spent gas intended for re-use in the process is caused to pass through a CO2 scrubber (23) and is then used to adjust the H2/CO ratio in the final reduction gas. <IMAGE>

Title: Cleaning wells
Inventor: SACCO FRANK JOSEPH
IPC: C09K8/524
Filed: 1989-12-15
Abstract: A process for controlling biomass and cleaning water injection wells and oil producing wells by injecting an oxidant into the pumped water injection stream. Chlorine dioxide or sodium chlorite, depending on the reactants present in the well, may be injected by means of a stinger, a spool or a coiled tube into the pumped water injection stream. Chlorine dioxide is generated at the site and may be generated by any one of several known processes. Hydrochloric acid or other proton donor stream, a water stream, and a stream containing sodium chlorate, sodium chlorite, and optional sodium chloride may be mixed at an elevated pressure to create chlorine dioxide. The elevated pressure of the chlorine dioxide stream is maintained at or boosted to a level greater than the pressure of the water injection or oil-producing well to aid in the injection of the chlorine dioxide stream either from generation to the well or through a booster pump mechanism to the well. Elevated pressure is maintained during application at a level to maintain the chlorine dioxide in solution.

Title: Computer with adaptive bandwidth moving average filter
Inventor: MOHTASHEMI ABDI
IPC: H03H17/02
Filed: 1991-10-01
Abstract: A computer is programmed to provide a moving average filter process which designates, 50, an initial filter constant to control the filter response time; maintains a moving average signal value; finds, 54, a difference between the moving average and each new signal sample amplitude before the new amplitude is included in the moving average; updates, 66, the average by adding to it, at a time of each new signal sample, a value calculated by dividing the difference by the initial filter constant; and when a sequential plurality of the found difference values manifest an identical polarity, divides, 64, the initial filter constant by an integer factor which thereby reduces the filter response time. When, by contrast, a found difference value manifests a different polarity from an immediately preceding found difference value, the filter constant is multiplied, 68, by an integer factor so as to increase the response time. <IMAGE>
