Abstract: The invention relates to a hydromechanical tool or workpiece clamping apparatus comprising at least one spring clamping cylinder connected to a release conduit and adapted to be hydraulically operated against a spring force to a release position, a pump connected to said release conduit and operable for a release operation, and a discharge conduit extending from said release conduit to a fluid reservoir and including a discharge control element for discharging the pressurized fluid from said spring clamping cylinder to said reservoir after deenergization of said pump. A known clamping apparatus of this type has a solenoid poppet valve disposed in said discharge conduit and operable to close said discharge conduit for the release operation and to be actuated to a flow-through position and maintained therein for the clamping operation. The solenoid valve is expensive and requires separate control means. In contrast thereto, the invention provides the use of a discharge control element in the form of a simple bypass shutter the flow resistance of which at a constant output flow rate of the pump is greater than the pressure required for overcoming the spring force in a release operation.

Abstract: To provide such a process for driving a coal-winning gallery in the floor of a seam with a short-wall face as well as devices particularly suitable for carrying it out, which permit the cutting work of the road-driving machines and the collecting of the extracted material to be carried out partly at the same time, the invention proposes that the short-wall face advances ahead of the driving of the gallery and the debris produced during driving is broken down and collected in such a way that, apart from the actual coal-winning gallery (7), two accompanying ditches (23) are produced. During driving, the ventilation in the two accompanying ditches (23) and in the actual coal-winning gallery (7) is antitropal, but during subsequent extraction it is homotropal. A device particularly suitable for carrying out the process comprises a coal-getting machine (1), a face conveyor (2) and a self-advancing support (3), which are linked to one another by means of control devices or a process control in such a way that the individual, technically necessary working operations proceed on the various system components in automatic sequence. <IMAGE>

Abstract: Les appareils connus de traitement de combustible contenant de l'asphaltène présentent des avantages de ne pas pouvoir réduire suffisamment la taille des particules d'asphaltène indésirablement grandes dans des huiles de pétrole lourdes. Le problème sus-mentionné est résolu par l'utilisation d'un appareil comprenant une série de lames de cisaillement serrées les unes par rapport aux autres qui sont en contact avec l'écoulement de liquide. Les lames sont portées par des pièces en forme d'hélices (14, 26) et sont montées sur un arbre axial (15) dans un conduit (11). Des groupes (12, 24, 35, 40 et 50) des pièces portant les lames de cisaillement sont prévues axialement le long de l'arbre. Les pièces de chaque groupe ont une orientation et configuration uniques par rapport aux pièces d'un autre groupe. Du mazout contenant des particules d'asphaltène s'écoule le long de l'arbre (15). Le mazout est mis en contact et conditionné par les lames de cisaillement. Les particules d'asphaltène sont réduites jusqu'à avoir une taille extrêmement petite de manière à être brûlées facilement dans une chaudière et retrouver des matières particulaires de taille réduite dans l'effluent sortant par la cheminée.

Abstract: A missile bulkhead rupture disc assembly (10) for disposition between adjacent solid propellant stages (14,16) which are ignited in sequential order has a central aperture (40) which receives an igniter for detonating the first stage of propellant. In preferred forms, the rupture disc comprises a pre­bulged frangible element (34) having a first burst pattern with a circular line of weakness (37) circum­scribing a central portion of the element sur­rounding the igniter, and the element also has a second burst pattern (44) comprising a plurality of lines of weakness which extend in a radial dir­ection outwardly from the circular line of weak­ness of the first burst pattern, and which are spaced from each other to define generally sector-­shaped petals or segments (46) of the frangible ele­ment. After ignition of the second stage (16) of propellant, the frangible element (34) initially bursts along the circular weakness line of the first burst pattern and thereafter ruptures along the radially extending lines of the second burst pattern to enable simultaneous, non-fragmenting outward movement of each of the segments toward the casing of the missile so that the materials discharged from the second propellant stage can be immediately directed to the tail end of the mis­sile. Advantageously, the circular weakness line (37) of the first burst pattern is scored to a depth deeper than a depth of score of the weakness lines of the second burst pattern (44) to ensure that the segments (46) completely break away from the central   portion before shifting outwardly toward the wall of the casing. Thereafter, the central portion of the frangible element and the adjacent igniter remain in stationary disposition in the center of the missile while the exhausting gases are dis­charged uniformly around the igniter.
