Abstract: Une seringue comporte un cylindre (1) logeant un plongeur (8) relié à un piston incorporant un scellement (7) au moyen d'un élément d'accouplement (9). Une bride (12) située sur l'élément d'accouplement (9) limite l'ampleur de mouvement de l'ensemble plongeur et piston, conjointement avec des cliquets (16). A mesure que l'on actionne le plongeur (18) dans une séquence d'évacuation d'air de la seringue, afin d'aspirer du liquide dans la seringue et ensuite d'éjecter à nouveau le liquide par une aiguille reliée à une sortie (5), des rainures de cames (11) situées aux extrémités de l'élément de couplage (9) fonctionnent avec des clés faisant saillie de sorte que l'élément d'accouplement (9) tourne par paliers. Ensuite, après avoir à nouveau retiré le plongeur (après éjection du liquide), les clés faisant saillie (10) sur la partie associée au joint (7) du piston se détachent des rainures de clavettes correspondantes (11) de sorte que l'on ne peut réutiliser la seringue.

Abstract: In a housing (12) enclosing a collector chamber (11) for filtering air laden with dust or other contaminants, a filter element (13) is mounted in line with a clean air opening (15) into the chamber through the housing (12) and is attached so that contaminated air coming into another housing opening (14) into the chamber must pass through the filter media for removing the contaminants from the air. From time to time a stream of pressurized cleaning air (24) is applied in the reverse direction through the first opening (15) to drive contaminants off the filter media. A deflector or diffuser (23) is located in line with the clean air opening (15) to diffuse the applied stream of cleaning air so that it does not directly impinge the filter element. The applied pressurized cleaning air stream (24) completely closes off the clean air (15) opening through which it is applied so that there can be no flow of the cleaning air back through the opening through which it enters so that the air pressure forces the cleaning air through the filter media to dislodge contaminants therefrom.

Abstract: Mit einem Verfahren zur Erzeugung von mechanischer Energie bei der NH3-Oxidation im HNO3-Prozeß soll eine Lösung geschaffen werden, mit welcher die zur Verfügung stehende Wärmeenergie besser genutzt werden kann, wobei insbesondere eine Ausnutzung der Wärmeenergie der NOx-Gase auf geringem Temperaturniveau möglich sein soll. Dies wird dadurch gelöst, daß vor der Oxidation flüssiges NH3 bei einem Druck, der um ein Mehrfaches über dem Druck bei der Verbrennung liegt, mittels der Prozeßwärme der erzeugten NOx-Gase verdampft und überhitzt wird, und daß anschließend das überhitzte NH3 energieerzeugend in einer Turbine entspannt wird.

Abstract: A fence (10) adapted for mounting on level or uneven terrain includes generally vertical posts (12), generally horizontal hollow rails (14a,14b), and connector clips (53) for attaching the rails to the posts. The connector clips are received within the inner cavity of the hollow rails and include an elongated opening (77) which is adapted to receive therethrough a stud (30) attached to the vertical post. About the opening and within the rail is provided a retaining structure (71) which facilitates easy insertion of the stud, at various angles, but securely resists withdrawal thereof. The length of the opening is substantially greater than the width of the stud received therethrough, so that deviations of the post from a true vertical position and/or deviations of the rail from a true horizontal position in the erection of the fence on an uneven terrain may be accommodated. An alternative form of clip (32) which is tubular is also described.

Abstract: A two-stage upflow process for coal gasification and an apparatus useful therefor. An oxygen-containing gas and a first increment of a coal-­in-water slurry are ignited in a horizontal fired slagging reactor by means of horizontal coaxial juxtaposed burner nozzles mounted in the reactor, thereby converting the oxygen, the coal, and the water into steam and gaseous combustion products. The discharge from the fired reactor is contacted overhead with a second increment of coal-water slurry in a vertical unfired heat-recovery unit connected to the upper end of the reactor. The heat evolved in the reactor is used in the heat recovery unit to convert the second increment of coal-water slurry into more steam, char and synthesis gas. The gas effluent is separated from the solid char, and synthesis gas is passed into a fire-tube boiler to recover heat and the cooled product gas is recovered as the desired fuel-rich product. The   solid char is reslurried and recycled to the fired reactor 3 for further combustion.

Abstract: A strong magnetic thrust force type actuator includes a first type of actuator, the permanent magnet of which is inserted between plate members of the primary magnetic member. When the insulated wire is activated by the primary magnetic member, a magnetic flux flows from a facing portion formed with a secondary magnetic member to a plate member, and then, to an adjacent plate member through a permanent magnet. In this adjacent plate member, another magnetic flux flows in there from another adjacent plate member through another permanent magnet. In a second type of actuator, the permanent magnet of which is inserted between the side surfaces of facing portions formed with the secondary magnetic member, a magnetic flux flows from a facing portion formed with the primary magnetic member to a facing portion of the secondary magnetic member, and then, to an adjacent facing portion through a permanent magnet, in this adjacent facing portion, another magnetic flux flows in there from another adjacent facing portion through another permanent magnet. Thus, as long as the pulse current flows in the coils wound around primary magnetic member, all facing portions of the primary magnetic member contribute to produce a magnetic thrust.

Abstract: The pump includes a discharge head having a pair of axially spaced end walls. The tank includes a housing in communication with a liquid outlet conduit and forms part of a substantially permanently stationary pipe column which receives clean coolant from the receptor side of a filtration system. By freely suspending the pump by its discharge head in the tank housing of the pipe column, the removal of the pump is facilitated by minimizing the criticality of its mounting connections in the filtration system. The pump is thus mounted for movement between operative and out-of-the-way positions whereby the pump may be readily removed from and reinstalled in the tank without disconnection or connection of pipe fittings within the tank and without aligning the pump with the receptor.
