摘要:
A zip fastener comprises a pair of tapes and coupling elements along adjacent edges of the tapes. The tapes are partly cut away to form a gap into which an end stop is moulded. The end stop is provided so as to extend along the tape edges away from the fastener coupling elements.

An additive composition comprises a Mannich reaction product of a) a polyisobutylene (PIB) alkylated hydroxyaromatic compound, b) an aldehyde, and c) an amine containing at least one reactive amino group where the PIB is derived from a conventional PIB and a high vinylidene PIB. A fuel additive concentrate composition, a fuel composition, and a method to reduce deposit formation in a fuel system of an internal combustion engine employ the additive composition that comprises the Mannich reaction product which is unexpectedly effective in reducing deposits. A PIB alkylated hydroxyaromatic compound, that is prepared from a mixture of high vinylidene and conventional PIBs, is both a functional additive and an intermediate to a functional additive and the process to prepare it involves running the alkylation reaction at 5 to 40° C.

This invention relates to proteins, termed INSP093, herein identified as secreted proteins, in particular, as members of the Interleukin (IL) 8-like chemokine family and to the use of these proteins and nucleic acid sequences from the encoding genes in the diagnosis, prevention and treatment of disease.
摘要:
A method of calibrating a gauge in particular for the measurement of film thickness, uses a calibration variable to compensate for short term changes in probe tip condition, instead of a constant value. A calibration constant is based only on the dielectric constant for a coating such as lacquer, and is independent of the probe tip variable.

The invention is directed to bioengineered vascular graft support prostheses prepared from cleaned tissue material derived from animal sources. The bioengineered graft prostheses of the invention are prepared using methods that preserve cell compatibility, strength, and bioremodelability of the processed tissue matrix. The bioengineered graft prostheses are used for implantation, repair, or for use in a mammalian host.

摘要:
A data capture system (1) has modular amplifier circuits (10) connected to modular capture circuits (11) within a rotor 2. Each capture circuit (11) has an FPGA (26) operation according to low-frequency and high-frequency state machines (M1, M2) to control ADCs (25) and upload from memories (30) to a host (15) During sampling, each FPGA (26) runs through a ready mode, a sampling mode, and again a ready mode according to a host command.
摘要:
A gravity meter comprises a casing, a vacuum tube mounted in the casing in a vibration-free manner, a sensor mechanism mounted within the vacuum tube, the sensor mechanism comprising two masses of different size acting on the respective arms of a beam balance comprising a material whose shape is arranged to change in response to changes in gravity and whose shape can be restored by the application of an electrical current thereto, and detector means arranged to provide from the restoring current an output representative of changes in gravity. The material is preferably a piezoelectric material.

A composition comprising a mixture of: (i) an aromatic polycarbonate; (ii) a graft copolymer including polyacrylonitrile; and, (iii) a non-crosslinked acrylic polymer having a weight average molecular weight (Mw) of less than or equal to 65,000 Daltons (Da).
摘要:
A matrix inverter is connected to a first and a second multi-phase A.C. voltage network. First inductive elements are connected to the first A.C. voltage network and second inductive elements are connected to the second A.C. voltage network. A switch matrix connects the ends of the first inductive elements, to the ends of the second inductive elements. The switch matrix has inverter units. A regulation arrangement is connected to control inputs of the inverter units. The matrix inverter has a first inverter unit, which is arranged between the ends of the first inductive circuit elements and earth potential. The matrix inverter has a second inverter unit, connected between the ends of the first inductive circuit elements and the ends of the second inductive circuit elements. The regulation arrangement insures that the electrical power flowing to the matrix inverter is equal to the electrical power flowing out of the matrix inverter.
