De la même manière, les données de mesure ou de calcul actuelles sont adaptées pour former le nouveau système de coordonnées, après quoi la distance entre les données de mesure ou de calcul actuelles, d'une part, et les données de mesure correspondant au groupe d'étude, d'autre part, est déterminée. Si cette distance dépasse une valeur prédéterminée, on établit lesquelles des variables d'état provoquent la déviation, par calcul de l'effet de la variable d'état respective sur la variance, le long de l'axe des coordonnées respectives dans le nouveau système de coordonnées.

Title: Paint roller and apparatus and method for making same.
Inventor: SEKAR CHANDR
IPC: B29C53/82
Filed: 1990-08-15
Abstract: This invention relates to a method and apparatus for making reusable paint rollers comprised of a core formed from thermoplastic material. Known methods and apparatus suffer from the drawbacks of bulky preformed thermoplastic tubular cores that are difficult to handle and expensive to transport, long assembly lines and the need for a heater. The above problems are solved by providing a method and apparatus for making reusable paint rollers comprised of a core formed from thermoplastic material. The thermoplastic material is formed into a core (18) about a stationary mandril (14). An adhesive is then applied to the core (18) thereupon a cover (30) is bonded thereto. In a first embodiment, the core (18) is formed by winding a plurality of thermoplastic strips (24, 26, 28) about the mandril (14). In a second embodiment, the core (18) is formed by applying liquified thermoplastic material to a driven belt (16) which transfers the thermoplastic material to the mandril (14).

Date May 30, 1991.A railway signalling system for the detection of a train within a defined section of track by means of track circuit apparatus utilizes the rails within the section as part of the track circuit. The rails are electrically shunted by the wheels and axles of a railway vehicle of the train in the section. The presence of a train is detected by detecting the change in the shunt impedance between the rails of the track circuit when a train enters the section. To improve the reliability of the track circuit a shunt assist circuit is provided. This shunt assist circuit comprises an inductive loop aerial provided on the railway vehicle so that it is closely coupled, inductively, with the rails, whereby when the loop aerial is energized from an alternating source, a current is induced in the wheel-rail-axle circuit.

Title: Process for the conversion of carbonaceous feedstocks to particulate carbon and methanol
Inventor: GROHSE EDWARD W
IPC: C10J3/54
Filed: 1990-10-18
Abstract: A process for the production of a pollutant-free particulate carbon (i.e., a substantially ash-, sulfur- and nitrogen-free carbon) from carbonaceous feedstocks (21). The basic process involves de-oxygenating one of the gas streams formed in a cyclic hydropyrolysis (10) methane pyrolysis (34) process in order to improve conversion of the initial carbonaceous feedstock. De-oxygenation is effected by catalytically converting carbon monoxide, carbon dioxide, and hydrogen contained in one of the pyrolysis gas streams (44), preferably the latter, to a methanol co-product. There are thus produced two products whose use is known per se, viz., a substantially pollutant-free particulate carbon black (53) and methanol (49). These products may be admixed in the form of a liquid slurry of carbon black in methanol.

Abstract: The invention relates to a process for the size-controlled machining of cylindrical external surfaces on workpieces on fine machining units, an abrasive being pressed against the rotating workpiece. In order to achieve highly accurate fine machining of the external surface in a machining station, provision is made for the diameter of the workpiece to be sensed before the machining and for the stock removal required to achieve the finished size to be calculated via a control device. During the machining of the workpiece the stock removal is continuously measured by a measuring device in order to end the machining when the calculated stock removal is achieved. <IMAGE>

Abstract: Porous ceramics having high porosity and a narrow pore size distribution are obtained by preparing a dilute slurry by mixing a ceramic raw material with a solution of such an organic high-molecular compound as ammonium alginate, which is capable of being gelled by reaction with an acid or a di- or more-valent cation, or by being heated or cooled. The slurry is contacted with a liquid or gel in which the acid or a di- or more-valent cation is present, or is heated or cooled to obtain a green ceramic gel body, and the obtained body fired. A hybrid porous ceramic is obtained if the slurry contains a di- or more-valent cation compound as a gelling agent. The porous ceramics have improved resistance and mechanical strength, typically compression strength, and a narrower pore size distribution, thus being suitable as catalyst carriers for high-temperature purposes or as carriers for bioreactors.
