Patent EP-0363047-A1 (EP)
Inventor: WILSON ERIC GEORGE
IPC: C23C8/26
Filed: 1989-09-21
Abstract: Nitrogen-strengthened alloys, especially steels, are produced by heating a combination of metal particles and a nitrogen donor, such as a chromium nitride, to make nitrogen available as a solute in the particles. The particles may be produced as a permeable preform for the process. The dissolved nitrogen leads to improved hardness, and higher strength is additionally obtained by the inclusion of a dispersant, such as yttria, in the particles.

Abstract: In a process and apparatus for treating glass-containing cooling water produced in glass factories, in a separating apparatus (9), sequentially, the cooling water is freed from hydrocarbons, and at least one primary inorganic flocculant selected from the group comprising chlorides, sulphates and chloride sulphates of metals is added to the cooling water. After this the resulting mixture is left to stand in a conditioning apparatus (13) until the formation of microflocks occurs. Following this a flocculation aid selected from the group comprising organic polymers having long chain molecules of high molecular weight is added to the cooling water containing the microflocks, and the mixture is left to stand in a sludge-receiving container (21) of a clarification device (16) until the formation of macroflocks and their setting. Subsequently the overflow liquid of the clarification device is removed and the sludge is fed from the sludge- receiving container to a filter apparatus (25). The filtrate is removed, and finally the predominant part of the total of removed mass flows of the overflow liquid and of the filtrate is passed via a cooling apparatus (30) to a spraying apparatus (3, 4) of a cooling circuit. The remaining part of the mass flows is removed from the circuit for desalting and the mass flow losses are made up by fresh water. <IMAGE>

Abstract: For encoding a stream of k-bit data bytes into a stream of m-bit code bytes satisfying given constraints, a coding principle and coder apparatus are disclosed which allow pipelined and parallel handling of the byte stream. Each data byte DB and an associated coder state indicator S are together converted into a code byte CB. The coder state indicator S(i) to be associated with a data byte DB(i) is obtained by logically combining the coder state indicator S(i-1) of the preceding data byte DB(i-1) and a state transition indicator T(i-1) derived from the latter. This allows the simultaneous generation of all coder state indicators S for a whole group (a word) of data bytes, thereby enabling the parallel and pipelined operation of the coder.

Abstract: Exchange of hydraulic energy between a depressurising fluid and a fluid being pumped on opposite sides of one or more double effect pistons. The piston operates in a double effect cylinder with water tight devices, non-return valves, and one or more control valves. One side of the piston is the 'pumping chamber', containing the fluid for pumping, and the other is the 'depressurisation chamber'. The greatest difference in pressure between the two chambers occurs during the 'inversion phases' and a number of devices are described for reducing this difference and minimising the risk of bursting the piston seal.

Abstract: L'invention concerne un système de mesure de la luminescence pour détecter la luminescence à des concentrations extrêmement faibles de fractions luminescentes. La méthode utilise un rayonnement alternatif provenant d'un laser (1) au niveau de plusieurs lieux géométriques d'une solution non homogène (3), où la puissance de rayonnement du laser (1) est maintenue constante, et les volumes irradiés de paires de lieux varient systématiquement à l'aide d'optiques (2) de définition de rayon. La probabilité que le même signal de luminescence est obtenu dans deux ou plusieurs mesures étant très faible, en comparant les mesures, on peut détecter un signal de luminescence faible en présence de niveaux de bruit relativement élevés. Diverses techniques sont décrites pour moduler l'irradiation et détecter les changements du signal.

Abstract: A protective seat (1) having a protective member (10) provided between a seat belt (7) and a seat body (2) to prevent the seat belt (7) from coming into direct contact with the sheet body (2) when the belt (7) is fastened tight. Also provided are engaging mechanisms (2c, 10d, 11, 12) that allow the protective member (10) to engage with the seat body (2) when a deceleration larger than a specified value is applied to a vehicle. As a result the seat belt (7) does not directly engage with the seat body (2) owing to the protective member (10) when the protective seat (1) is fixed to the car seat by fastening the seat belt (7) after passing it through the mounting hole of the seat body (2). Therefore, the reclining angle of the seat body (2) can be adjusted while keeping the seat belt (7) tensioned. Also, since the protective member (10) is engaged with the seat body (2) by the engaging mechanisms (2c, 10d, 11, 12) when a vehicle is quickly decelerated, the seat body (2) can be securely retained without changing the reclining posture.
