Patent EP-0025077-A1 (EP)
Inventor: BOURQUI GERALD
IPC: G01L1/22
Filed: 1979-09-06
Abstract: The two-wire or life-zero measuring system comprises measuring means (23) fed with direct current from a rectifier (12,13,14) connected to the secondary winding (9) of a high-frequency transformer of which the primary winding (8) is energized with direct-current pulses at a high frequency. The current flow in the primary winding depends on the load formed by the measuring means on the secondary winding. This current is measured and is in a linear relation to the current flow in the measuring means. Voltage peaks in the primary circuit, in the secondary circuit and in the current- measuring circuit and cut off by means of Zener diodes (4,24,33). 
     This measuring system is simple due to the two-wire measuring circuit and has an intrinsic safety partially due to the galvanic separation of the measuring circuit from the power circuit and the Zener diodes avoiding excess voltages in all circuits. The system is able to measure static and dynamic phenomena with passive measuring elements such as strain gauges or with active elements such as piezoelectric crystals controlling a current source in the secondary circuit.

Abstract: A method of manufacturing a steel exhibiting the favourable properties of half-calmed steel. The heads of calmed steel ingots have a more or less pronounced pipe which leads to the dead head, the size of which can be reduced only by expensive means, such as feeding and/or reheating. In contrast, half-calmed steels give off, during their solidification in the ingot mould, quantities of gases which can compensate for the space which would be caused by a pipe at the head of the ingot, by the formation of a multitude of cavities or blowholes. Attempts have been made to adjust the quantities of gases given off during solidification by adding specific quantities of calming agents to the steel. However, it has proved imposssible to control the evolution of gases in a totally reproducible manner. The object of the invention is to propose a method of manufacturing a steel exhibiting the favourable properties of half-calmed steel, while avoiding the disadvantages normally inherent in half-calmed steel. This object is achieved by the method which provides for casting, in an ingot mould, a totally calmed steel and treating the said steel by allowing a gas, capable of creating a multitude of cavities within the body of the ingot, to act inside the ingot mould during or after casting. This gas is preferably a neutral gas or a reducing gas which is top-blown or bottom-blown into the still unsolidified metal. It is also possible to blow in vapours of metals or solid materials which give off gases at high temperatures. The result is an ingot which exhibits a skin of excellent quality and a uniform internal condition having a multitude of mini-cavities which are uniformly distributed through the body of the ingot.

Abstract: The complexity of antigenic test material in tests which employ the antigen-antibody reaction increases the likelihood of false results. In particular, the complexity of antigenic test material in diagnostic techniquest increases the likelihood of false positive signals generated due to antibodies stimulated by organisms showing some but all antigenic properties with the test material. In conventional tests, a single positive or negative signal is obtained which is the result of a complex and undifferentiated array of structural components of an organism or material antigenically related to it. In contrast, the present invention greatly expands the use of the antigen-antibody reaction in analysis techniquest and diagnosis by providing a multi-signal. 
     The invention provides a method for producing an analytical antibody probe for detecting the presence of antibodies specific for particular protein and/or poly-  I  saccharide material, which method comprises disposing I upon a solid-state substrate in a pre-determined spatial relationship a set of differentiated antigenic components which have been derived from said protein or polysaccharide material, said set of differentiated antigenic components being selected such that at least a subset thereof is known to be reactive with said antibodies. The invention also embraces the analytical antibody probe as such and a corresponding method for analysing a sample to determine the presence and distribution of antibodies specific for particular protein and/or polysaccharide material.

Abstract: A method of operating a diesel engine is disclosed. The method requires the introduction into combustion chambers of the diesel engine of a diesel fuel, air and a catalyst material which lowers the temperature at which soot will be oxidized. The diesel fuel is burned in the combustion chambers of the diesel engine to form exhaust gases. These exhaust gases contain soot which is a by-product of the burning of the diesel fuel, and also contain the catalyst material in a highly dispersed oxide form. The exhaust gases are passed into a trap structure in which the soot is trapped. The highly dispersed catalyst material is trapped on the soot during any one, any combination, or all of the following: (a) the time the soot is in the combustion chamber, (b) the time the soot is passing from the combustion chambers of the diesel engine to the trap structure, (c) while the soot is trapped in the trap structure. Periodically, the temperature within the trap structure is raised to a temperature which is sufficient to permit catalytic oxidation of some or all of the soot trapped in the trap structure. This temperature of catalytic oxidation is lower than the temperature at which the soot would oxidize if no catalyst material was present. The catalyst is preferably incorporated in the diesel fuel composition.
