Patent GB-8528652-D0 (GB)
Title: Frequency controlled resonant regulator
IPC: H02M3/28
Filed: 1985-11-21
Abstract: The primary winding of a high leakage inductance power tranformer is coupled to a source of unregulated voltage and to a square wave voltage generator that includes first and second alternately conducting output switching transistors. A voltage controlled oscillator establishes the operating frequency of the voltage generator. A resonating capacitor is coupled to a transformer secondary winding that is loosely coupled with the primary winding. The capacitor forms a series tuned circuit with the leakage inductance between the primary and secondary windings of the transformer. The operating point of the tuned circuit voltage verses frequency characteristic curve determines the amplitude of the generally sinusoidal output voltage across the secondary winding, in accordance with the operating frequency of the square wave voltage generator. A feedback circuit senses the amplitude of the output voltage and varies the frequency of the voltage controlled oscillator to regulate the output voltage.

Title: Aryl carbonyl compounds
IPC: C07C49/84
Filed: 1986-09-30
Abstract: Friedel Crafts preparation of aryl carbonyl compounds having an exceptionally high degree of isomeric purity and freedom from by-products can be achieved by adding to the Lewis acid reaction system a protic controlling agent selected from ROX, water, RCOOX, RSO3X, and ROY, wherein R is organic, X is hydrogen or metal, and Y is metal. Contrary to conventional expectation, the protic agent does not significantly alkylate or acylate the Friedel Crafts reaction product.

Abstract: PCT No. PCT/GB91/00241 Sec. 371 Date Aug. 24, 1992 Sec. 102(e) Date Aug. 24, 1992 PCT Filed Feb. 18, 1991 PCT Pub. No. WO91/13058 PCT Pub. Date Sep. 5, 1991.A dilute solution of a lower aliphatic peracid such as peracetic acid, having an equilibrium composition, is produced by contacting hydrogen peroxide with a lower aliphatic acid each at initial high concentrations in an aqueous reaction mixture to rapidly form a reaction mixture containing, for example, up to 30% by weight of peracid and diluting the reaction mixture with water and with any required quantities of lower aliphatic acid and/or hydrogen peroxide to reproduce the equilibrium composition of the dilute solution, the process being characterized in that the reaction mixture rich in lower aliphatic peracid is diluted before it has itself reached equilibrium, for example when it contains from 20 to 80% of its potential equilibrated content of peracid. The process provides a quick plant-efficient process for the production of stable dilute lower aliphatic peracid solutions for industrial disinfection purposes or for personal or domestic hygiene use.

Title: Leakage detection
IPC: F28D7/00
Filed: 1994-12-14
Abstract: A vessel such as a dairy pasteuriser having a path B for product and a separate path A for coolant in intimate relationship is tested for leaks by circulating a donor fluid under pressure in path A whilst a recipient fluid such as clean tap water is circulated in path B. If the donor fluid is an electrolyte, a probe 12 is placed in path B to measure the conductivity of the recipient fluid. A rise in conductivity over a period indicates leakage between the two paths, the rate of change indicating the size of the leak.

Title: Data communications system and method therefor
IPC: H04L1/18
Filed: 1997-07-31
Abstract: A data communication system comprises a transmitter for transmitting a fixed-length block of information, and a receiver for receiving the block. The fixed length block includes a plurality of sub-blocks, each having a variable length depending upon the data. When an amount of transmission data has a size less than that of the fixed-length data block the transmitter repeatedly arranges the information within the same fixed-length block in order to form the block. Thus the unused portion of the fixed-length block is effectively utilized to increase the reliability of the data communication. Additionally, error check codes may be stored within the data area to further increase reliability.

Abstract: The present invention relates to a new method for enhancement of source coding systems using high-frequency reconstruction. The invention teaches that tonal signals can be classified as either pulse-train-like or non-pulse-train-like. Relying on this classification, significant improvements on the perceived audio quality can be obtained by adaptive switching of transposers. The invention shows that the so-switched transposers must have fundamental differences in their characteristics.

Inventor: HELLBERG PER-ERIK
IPC: C09K23/42
Filed: 2001-08-23
Abstract: The present invention relates to a new tertiary or quaternary nitrogen-containing ortho ester-based surfactant, where the hydrophobic and hydrophilic parts are attached by separate ortho ester linkages. The ortho ester surfactants are stable in alkaline solutions, but are readily hydrolysed in acidic solutions. Since the hydrophobic and the hydrophilic parts of the surfactants reside in different substituents of the ortho ester, the surface activity is lost upon dydrolysis. The invention also relates to a process for making the ortho ester-based surfactants, where low molecular weight ortho esters are used as starting materials. These low molecular weight ortho esters are reacted with a hydrophobic component, which is an alcohol or an alkoxylated alcohol, and hydrophilic component, which is an alkanolamine or an alkoxylated alkanolamine. The molar amounts of the reactants are preferably 1-2 moles of the hydrophilic component per mole orthoester and 1-2 moles of the hydrophobic component per mole ortho ester. By this process surface active amino ortho esters are obtained. To obtain quaternary aunonium ortho esters, the amnino ortho esters are reacted with an alkylating reagent such as methyl chloride or dimethyl sulphate. The nitrogen-containing ortho esters are surface active and form micelles, they are efficient in lowering the surface tension and have excellent wetting properties. They are suitable to be used in all applications where quaternary ammonium surfactants anad tertiary amine surfactants are typically used.

Abstract: In an airbourne ground-ranging monopulse radar system the sum (S), azimuth difference (A) and elevation difference (E) signals derived from a plurality of statistically-independent radar returns are analysed to obtain an estimate of the orientation of an iso-probability-density surface defining (with respect to corresponding coordinate axes) S, A and E amplitude combinations of a particular probability density. The orientation of this iso-probability surface indicates the target elevation off boresight, and is independent of any across-track ground slope. In a practical embodiment (fig. 8) the two difference signals are first split into separate in-phase and quadrature components A', A", E', E" relative to the sum signal S. Variances and co-variances of these four components and S are then derived (10 - 15), and an appropriate function thereof computed (16 - 22). <IMAGE>
