Title: Suspension of dyes and optical brighteners in structured surfactants
Inventor: HASLOP WILLIAM PAUL
IPC: C09B67/46
Filed: 1991-08-09
Abstract: A dye suspension comprises an aqueous structural surfactant having suspended therein particles or droplets of water-insoluble or sparingly soluble dye, e.g. disperse dye or optical brightener. The surfactant preferably comprises a spherulitic or open lamellar structure interspersed with an aqueous phase. The suspensions are preferably free from organic solvents and polymeric thickening agents, but optionally contain electrolytes (sufficient to structure the surfactant) antifoams and suspending agents. A disperse dye is optionally encapsulated in or coacervated with a water-soluble film-forming polymer, e.g. polyvinyl pyrrolidone. The suspensions are preferably concentrates containing 1 - 80 wt% of suspended phase, for use as detergent additives or printing pastes, or for dilution for form dyebaths.

Title: Diagnostic aid
Inventor: ILLUM LISBETH
IPC: A61K49/22
Filed: 1992-07-03
Abstract: Hollow (i.e. gas- or vapour-filled) microcapsules, for example of albumin, are prepared by forming a shell around a solid or liquid core and subsequently removing the core. The core may be a volatile oil such as perfluorohexane. The shell may be made by simple or complex coacervation, oil/water/oil double emulsion, or MSIEP (minimisation of solubility at isoelectric point) methods, followed by chemical or heat hardening to render it water-insoluble. When the double emulsion method is used, the microcapsules have a honeycomb appearance with multiple gas-filled chambers. The microcapsules can be used for echocardiography.

Title: A segment descriptor cache for a microprocessor
Inventor: HAMMOND GARY N
IPC: G06F12/10
Filed: 1992-08-06
Abstract: An improved memory segmentation system in a microprocessor, for generating a segment descriptor based on a segment selector, comprises an associative descriptor cache 570 to retain previously fetched, unscrambled, and tested descriptors for subsequent access by the same selectors. If on a memory access the descriptor is not found in the descriptor cache, the selector 501 is used to fetch a scrambled, raw descriptor from memory 530. The scrambled descriptor is then unscrambled at 550 before loading into a segment register 560. The same unscrambled descriptor is also used to update the descriptor cache 570 such that it may be found in the future. The descriptor unscrambling is necessitated by provision of backward compatibility with prior processor architectures. <IMAGE>

Title: A method for laying a wire in a junction box
Inventor: FUDOO EIJI
IPC: B60R16/02
Filed: 1993-02-18
Abstract: A method for laying wire in a junction box comprises the steps of: setting (S1) a covered wire E on a wiring plate along a wiring pattern arranged on said wiring plate by causing a relative movement between a wire feeder which successively feeds a single wire and the wiring plate along guide means formed on the wiring plate; cutting off (S2) portions unnecessary for conductive circuits from the wiring set on the wiring plate; and forming (S3) the conductive circuits in the junction box by inserting the wire remaining on the wiring plate into the wire-coupling portions of connecting terminals 31 to 38 secured to a base and by removing the junction box from the wiring plate. Thus, it is possible to speed up the wire-laying work in a junction box having many conductive circuits. <IMAGE>

Filed: 1993-03-16
Abstract: An artificial lures (1) for use in fly-fishing, in order to simulate the appearance of insert wings, a laminate of plastics sheet material, for example polyethylene, is bonded together to enclose a non-uniform coating or layer (32) of translucent ink or dye. Preferably the laminate is formed of portions of sheet materials which are of differing thickness (28, 30) so that the effect of heat and pressure acts to curl the laminate slightly to impart a characteristic curve to the simulated wings (14'').

Title: Engine fuel metering system.
Inventor: LOXLEY RUSSELL ALLAN
IPC: F02C9/26
Filed: 1993-09-08
Abstract: The amount of fuel supplied by a low pressure pump 24 and a high pressure pump 28 to combustion means 14 is controlled by a control unit 30. If most of the fuel delivered by the pumps, 24 and 28, is required by the engine 10 a clutch 32 engages to provide a direct mechanical drive between the pumps 24 and 28 so that they are driven by gear train 11 at the same speed. However if the combustion equipment 14 requires a reduced flow of fuel the clutch 29 disengages and the excess fuel is diverted by a valve 34 to a turbine 36. The turbine 36 drives the low pressure pump 24 at a higher speed than the speed of the high pressure pump 28. The energy of the diverted fuel is converted to mechanical energy to drive the turbine 36 so that the temperature rise of the diverted fuel is reduced. <IMAGE>

Patent GB-2271850-A (GB)
Title: Non-radioactive hybridisation assay for pathogens
Inventor: AYYANATHAN KASIRAJAN
IPC: C12Q1/68
Filed: 1993-11-23
Abstract: A non-radioactive assay for pathogens such as Plasmodium Falciparum and Shigella sp. is disclosed. Samples containing blood and body fluids are contacted with a lysing solution comprising guanidine hydrochloride, SLS and Triton-X-100 (RTM). The DNA is denatured and hybridised with a nucleotide probe (which may be label led) in solution before the hybrids are captured on a microtitre plate coated with a hybridisation probe. The plate is washed with a solution comprising SSC, Triton-X-100 (RTM) and SDS. The assay is sensitive because the DNA is substantially undegraded during the process and the rate of hybridisation in solution prior to capture on a solid substrate is high. Moreover, immobilisation on a microtitre plate permits the use of a colourmetric detection system since contaminating products from the sample can be effectively removed by a washing step. Specific nucleotide probes for P. falciparum are also disclosed.
