Abstract: Ammonium sulphate is recovered by crystallisation from an aqueous waste stream (1) resulting from an acrylonitrile production process, at least part of the mother liquor from the crystallisation being treated with methanol (10, 8, 7) to form additional solid ammonium sulphate and a liquid comprising water, methanol and tar. Methanol is recovered from this liquid for re-use and the residue can be incinerated. As well as increasing the yield of ammonium sulphate, the method solves a difficult waste disposal problem.

Abstract: Un conduit de conduction de radiation fonctionne comme un filtre à axe décentré et comme un dispositif de renforcement du contraste pour un appareil de mise en images. Un noyau de verre transparent possède un axe aligné avec la ligne de visée de l'appareil. Un revêtement est prévu, lequel possède le même indice de réfraction et le même coefficient de dilatation thermique que le noyau de verre, à l'exception d'un petit pourcentage du verre du revêtement qui est fabriqué avec des feuilles ou fibres fines de verre absorbant alignées sensiblement radialement sur l'axe du conduit et distribuées au hasard dans le volume du revêtement. L'interface entre le verre du noyau et le verre du revêtement de même composition n'implique pas de réflection ou de réfraction, et la lumière non axiale passe au travers de l'interface et est emprisonnée dans les fibres noires absorbantes. Là, elle est réfléchie et diminuée jusqu'à être totalement absorbée. Le conduit peut être fabriqué comme suit: formation d'une feuille plate de verre contenant des fibres ou feuilles parallèles au hasard de verre absorbant, découpage de la feuille en bandes biseautées, assemblage des bandes en une configuration cylindrique en plaçant les éléments absorbants radialement à l'axe, introduction d'un noyau de verre transparent, et fusionnement de l'assemblage et du noyau.

Granted: 1989-10-11
Abstract: A spray gun for applying a film to a workpiece has a spray head provided with an annular nozzle designed to discharge material which is to undergo pneumatic atomization. A second annular nozzle surrounds the pneumatic material discharge nozzle and is designed to discharge atomizing air for pneumatic atomization of the material issuing from the pneumatic material discharge nozzle. The spray head is further provided with an additional material discharge nozzle designed to discharge material which is to undergo hydrostatic atomization. The hydrostatic material discharge nozzle is disposed centrally of, and is surrounded by, the pneumatic material discharge nozzle. The hydrostatic material discharge nozzle forms a first spray of hydrostatically atomized material while the annular nozzles form a hollow conical second spray which surrounds the first spray when both sprays are on simultaneously. The spray gun is capable of creating a spray pattern exhibiting the characteristics of a pneumatically generated spray as well as the characteristics of a hydrostatically generated spray. The material supplied to the pneumatic material discharge nozzle may be the same as that supplied to the hydrostatic material discharge nozzle or each of these nozzles may be supplied with a different component of a two-component substance.

Abstract: A belt pulley 1 for a belt drive presenting a belt groove 3 having a transition area to the radially outer cylindrical surface 2' which is rounded at a decreasing radius. Previously, this corner was merely chamfered or rounded at a small radius, which in use led to mechanical damage to the belt placed on it. This invention provides a parabola-shaped contour for the transition area, which effectively avoids mechanical damage to the belt, wherein the largest radius RO of the transition curve is located at the later's junction with the groove face 4'.

Granted: 1993-03-24
Abstract: A distributed sensor system including an optical source (100) having a short coherence length for optionally continuously monitoring each sensor in the system. In one preferred embodiment, an array of fiber-optic sensors (110) are organized in a ladder configuration, with the sensors positioned in spaced relation and defining the rungs of the ladder. Light transmitted through the sensors is multiplexed onto a return arm (114) of the ladder, with sensor spacing being such that interference between light from different sensors is prevented. The multiplexed signals are received by an optical fiber receiver (118, 120) which couples the mutiplexed light with an interfering optical reference signal to produce a phase difference signal representing conditions influencing selected sensors. Embodiments are disclosed for use of either pulsed or continuous wave light sources. In another preferred embodiment, the sensors comprise a plurality of interferometers (404,406) connected in series configuration by a common optical fiber (402), which provides multiplexed output signals from the sensors to another plurality of interferometers (418, 420) comprising receivers. Functional equivalents of the series configuration provide sensors and receivers comprising birefringent or two-mode fiber. The optical path length differences between each pair of sensor arms (409, 410, 411 and 412) are selected to prevent interference between the multiplexed sensor output signals from the various sensors. The optical path lengths through the sensors (404, 406) and receivers (418, 420) are structured so that each receiver (418, 420) produces a phase difference signal relating to conditions affecting light transmission through a specific sensor (404, 406). A phase and amplitude modulation technique is disclosed for providing heterodyned output signals from the dristributed sensor system.

Abstract: A memory circuit (10) which has a select and a deselect mode. The memory circuit (10), as part of its technique for quickly accessing data, includes circuitry for generating a pulse (*ANTX) in response to detecting an address transition. When the memory circuit switches from the deselect mode to the select mode, there appears to be an address transition even when there is not an address transition. In order to prevent a delay associated from interpreting such false transition as an actual transition, thedetection of address transitions is suppressed for a predetermined delay time following the transition from the select to deselect modes.

Abstract: The bogie for a rail vehicle comprises a minimum of two wheelsets and at least one passive steering device (30). Each of these connects two wheelsets (3, 3') together so that they can swivel. It has a third control lever (32) with a coupling point (31) for forming a swivel connection with a coach body. The pivot points (38, 39) for swivelling the wheelsets (3, 3') are located on one side of the longitudinal centre plane (4) of the bogie (2, 2') and the coupling point (31) for the coach body on the other side of the longitudinal centre plane (4) or actually in this. This bogie is of particular advantage on vehicles negotiating small radii of curvature such as trams and municipal railways since the flexible rubber elements used on the swivel and pivot points of the steering device have optimum conditions with regard to their angle of torsion. <IMAGE>

Granted: 1992-03-04
Abstract: Une séparation de cassure satisfaisante de composants en métal léger est difficile à obtenir à cause de la ductilité inhérente du matériau qui se traduit par la déformation du métal lors de la séparation. Lorsqu'une telle déformation se produit, les deux moitiés de la cassure ne correspondent pas correctement l'une avec l'autre. L'invention prévoit le durcissement local d'un composant en métal léger dans la région de cassure, et les éventuelles techniques proposées consistent à former le composant autour d'un insert en matériau cassant (24), à modifier localement la structure interne du métal et à couler une armature en fil de fer cassant (26) dans le métal. Toutes ces opérations techniques peuvent également s'accompagner de la formation d'une encoche d'amplification de la contrainte (28) au niveau de la surface du composant.
