Abstract: In order to permit operation with preheating of the combustion-supporting air to 50 or preferably 65 percent or more of the oven temperature, the air is fed to a ceramic burner tube through an annular nozzle directing it in an annular jet along the interior walls of the burner tube. For a burner of low back pressure having no restriction at the mouth of the ceramic burner tube, the ceramic burner tube fits over the end of the outer member of the annular nozzle and some of the combustion product gas, flowing from the oven into the burner structure for countercurrent of the preheating of the air supply, is sucked into the underpressure zone between the annular air jet and the inner wall of the burner tube through a small annular gap where the burner tube fits on the air-supply nozzle. For a burner design involving considerable back pressure, the ceramic burner tube fits within the outer wall of the annular nozzle with a very small clearance in the overlap and some of the supplied air, which is at higher pressure than the exit in gases, escapes through the gap around the outside of the burner tube and cools the burner tube and the adjacent overlapping portion of the air supply tube.

Abstract: A valve for a pressurized dispensing container comprises a valve housing (11) defining a valve chamber and having at its lower end an inlet for pressurized material. An annular flexible seal (12) closes the upper end of the chamber, there is a cup-schaped valve member (13) with the chamber, and a hollow actuator stem (16) extends in sliding, sealed relation through the seal (12) and engages the valve member (13) at its lower end. A spring (14) urges the valve member (13) upwardly into sealing engagement with the seal (12), the actuator stem (16) being manually moveable downwardly against the action of the spring (14) to unseal the valve member (13) and open thevalve. Thewall of the actuator stem (16) includes at least one radial, aperture (24) adjacent to but spaced from the lower end (26) of the actuator stem (16) and defining a lip portion (25) adjacent the lower end (26) of the actuator (16). The aperture or apertures (24) place the interior of the actuator stem (16) in communication with the interior of the valve member (13) and the lip portion (25) serves to restrain the lower end of actuator stem (16) from passing through the seal (12) if the actuator stem is moved upwardly of the seal.

IPC: C01B3/38

Abstract: In the production of methanol from a methane-containing gaseous feedstock such as natural gas by steam reforming the gas and treating the reformate to produce methanol by inter-reaction of the hydrogen and oxides of carbon in the reformate, the use of part of the feedstock to fire the reformer is avoided by immersing the reformer reactor tubes in a fluidised bed heated by the combustion of a low grade, solid, fossil-based fuel such as coal, lignite, oil shale or asphaltic residues from oil refining. By pressurising the fluidised bed, all the power requirements of the process can be obtained by expansion of the flue gas, which can also provide the C0 2  balance for the methanol synthesis, and a compres- sorcan be omitted.

Abstract: The invention relates to a device permitting the storage of at least one line connecting a plurality of floats mounted in series on this line and the rapid deployment of this line. It is composed of a plurality of float elements (1), each comprising at least one volume of low density (2) and at least one line support such as a spool (3). These floats nest in one another in order to form a compact volume, leaving between them just sufficient volume to store the line which is fastened on each float (1) and a certain length of which is wound on each line support. When the reel is launched into the water, the floats separate from one another, while remaining connected by means of the deployed line. The invention can be used for sea rescue and for various tasks at sea. <IMAGE>

Abstract: To reduce the piston velocity in a cylinder as the piston approaches the end positions, a signal transmitter is provided for sensing the position of a part driven by means of the piston and cylinder assembly, and thus of the piston in the cylinder. The signal of the signal transmitter is applied to a control unit in which it is compared with a signal from an actuator means. The signal from the actuator means controls the extension and shortening of the piston and cylinder assembly and the velocity at which this occurs, and may be positive or negative. The comparison of signals is so exploited that if it is established by this comparison that the piston is not in the areas of the end positions or, alternatively is in these areas but is activated by the actuator means to move away therefrom, the signal from the actuator means is not acted upon, whereas if the piston is in these areas and approaches the end positions, the hydraulic fluid supply to the piston and cylinder assembly is continuously reduced.

Abstract: This invention provides an improved method by which a plasma-arc cutting torch (77) can be used to cut a metal plate (125). The method basically comprises operating the torch (77) with its lowermost end portion submerged in a layer or water provided over the workpiece. In order to enable automatic adjustment of the torch (77) to the appropriate working height above the submerged workpiece, the torch is mounted on a mechanism which permits relative up and down movement between the torch (77) and a support member (88). The torch is lowered towards the workpiece (125) so that it eventually engages the workpiece and is caused to move upwardly relative to the support (88). This upward movement of the torch is detected and is used to initiate raising of the support (88) to bring the torch to its operational height above the workpiece.

Abstract: A closure for a large sized opening (102) in a pressure vessel (103) has a lid (101) longitudinally movable between an open position and a covering position in which it is aligned with the opening (102) but spaced apart from it, and perpendicularly displaceable between the covering position and a sealing position in which it engages the sealing edge (104) of the opening (103). The lid (101) is moved by a hydraulic or pneumatic ram(116) between the open and covering positions and iscarri- ed by rollers (109) mounted on shafts (106,106a) affixed to the lid, which run on longitudinal support surfaces (119). The shafts (106, 106a) are rotatably mounted in bearings (107) fixed to the lid and are coupled together (112,112a, 113) for simultaneous rotation, while the rollers (109) are eccentric relative to the bearings (107). The ram (116) applies torque to the shafts (106, 106a) in one sense during closing movement of the lid (101) and in the opposite sense during opening movement of the lid (101). A follower member (120) fixedly secured to one (106) of the shafts engages guide surface (119) to prevent the shafts (106, 106a) rotating during movement of the lid between the open and covering positions. The guide surface has an aperture (123) in it through which the follower member (120) passes when the lid reaches the covering position so that the shafts (106, 106a) rotate and the lid (101) is displaced from the covering position to the sealing position by the relative eccentricity of the rollers (109) and bearings (107). A cam surface is provided for guiding the follower member (120) during return displacement of the lid between the sealing position and the covering position.

The position control system includes a drive arrangement responsive to a drive input signal for moving the controlled member. The position control system also includes a coded array device that moves in a predetermined path correlated to the controlled member and defines an array of energy transmissive members. The servo control arrangement includes two energy generation sources and means for alternately energizing the sources. The sources are arranged side by side at a detection station along the predetermined path of the coded array device. The servo control arrangement also includes energy detection means for generating an output signal corresponding to the relative level of energy received from each of the sources. The coded array device is positioned intermediate the detection means and the sources such that the relative energy received by the detection means is dependent on the position of the energy transmissive member at the detection station. The servo control arrangement further includes control means responsive to the energy detection means for generating the drive input signal.
