摘要： A fluidic oscillator for a shunt flowmeter for measuring gas flow through a pipeline, comprises three sections arranged in series and providing a generally U-shaped flow path through the oscillator. The first section has an inlet end connectable to an outlet port in the pipeline and leading to a main fluid nozzle communicating with an interaction chamber, diverging sidewalls of the flow path extending downstream of the interaction chamber, and feedback loops extending from the diverging sidewalls to control nozzles at the interaction chamber. The second section is juxtaposed to the first section to return the flow to the pipeline and has an outlet end connectable to a return port in the pipeline. The second section includes diverging sidewalls terminating in a flow restriction adjacent the outlet end, and a flow-splitter body physically dividing the flow. Sensor ports are provided on opposite sides of the flow-splitting body for the connection of a flow sensor to detect oscillations in the gas flow through the second section. A third section interconnects the outlet end of the first section with the inlet end of the second section and includes a flow-splitting partition aligned with the flow-splitting body. A flow-splitting member is provided at and adjacent the outlet end of the first section for dividing the flow from the interaction chamber prior to entry into the third section.

摘要： A rack arrangement for supporting a load, for example above the roof of a vehicle body, comprises a pair of substantially parallel elongate guide members 3 each having a lower upwardly extending portion 3a and an upper load supporting portion 3b. A load carrier member 4 is rockably connected to the guide members and is manually slidable from a lowered position upwardly along the lower guide member portions 3a onto the supporting portions 3b to a load storage position. Means is provided for releasably retaining the carrier member in the load storage position, for example a cup-like recess 17 which locates the base of a handle 12 for the carrier member.

摘要： The regenerative heating apparatus (FIG. 1) comprises a pair of regenerators 51a and 51b arranged so that in use while one is being heated by waste gas, the other is preheating air for the combustion of fuel. A reversing valve 58 is connected to each lower end 91a and 91b of the regenerators 51a and 51b, the valve 58 connecting the regenerators 51a and 51b to an inlet 99 for receiving air and an outlet 100 for discharge of the waste gas. The reversing valve 58 is reversible to connect one regenerator to the inlet and the other regenerator to the outlet. Each regenerator incorporates at its upper end a burner (B1 and B2) with as shown in FIG. 2 a body having a passage 2 formed with openings 3 and 4. The opening 4 serves to receive air for combustion when its regenerator is preheating air or to discharge waste gas to the regenerator while the opening 3 serves to supply combusted fuel and air to the furnace 90 or to receive waste gas from the furnace 90. Each burner has an assembly 5 for injecting fuel and air into the passage 2 and the fuel and air first mix in a nozzle 31 with the fuel being ignited by an electrode 47. The fuel is combusted in a precombustion chamber 32 before entering the main combustion chamber 16. The fuel is partially or fully precombusted irrespective of the mode in which the burner is operating to avoid prepurging with or re-ignition between regenerator operating cycles.

摘要： A flame support 20 has a plurality of discrete regions 22 through which fuel/air mixture can pass by means of burner ports 13 which extend through the support to a multiplicity of openings 25 at the flame supporting side 24. The support 20 comprises barriers 21/26 which extend between and separate the discrete regions 22. The barriers serve to prevent the passage of fuel/air mixture from upstream of the support to the downstream side 24 of the support in a region between the discrete regions. In burners provided with such a flame support, the likelihood of resonant combustion noise occurring has been found to be reduced.

摘要： A carburetor (2) to supply a mixture of fuel gas and combustion air to a reciprocating internal combustion engine. The carburetor has a venturi (4) and a throttle (10) including a throttle valve (24). A tear-drop shaped obstruction (36) is mounted in the venturi throat (18) on diametrically opposed radial arms (66). The narrowest part of the tubular gap (46) between the walls of venturi (4) and the obstruction (36) is at gap (48). A continuous slot (50) in the throat wall (18) encircles the obstruction and opens into gap (48). Another continuous slot (70) encircling the obstruction (36) is formed therein and also opens into the gap (48). Fuel gas is supplied to the slots (50 and 70) through passages (52, 74 and 72).

摘要： A heat meter for measuring the amount of heat consumed in a region. A heat exchanger is supplied with heated fluid through an inlet pipe which carries temperature sensors for sending signals to a control. The control also receives signals from a temperature sensor in an outlet pipe carrying fluid away from the region. A low power electric heater is mounted between the sensors to add a known amount of heat to the fluid. The control calculates the heat power consumed in the region based on the temperature difference across the regions and the temperature difference across the region and the temperature difference across the heater.

摘要： An in-pipe vehicle for carrying out at least one operation in a pipeline. The vehicle comprises a train of modules 11-16 interlinked by suspension units 17 to allow serpentine movement through pipe bends. The vehicle train has its own internal power supply and drive mechanism in respective modules. A detector module 14 determines the presence of a service junction and a manipulative module 13 allows the vehicle to be temporarily wedged in the pipeline whilst providing rotational movement to facilitate the desired operation at the junction. This can include drilling and welding of a service pipe to the main using appropriate modules.

摘要： A process for preparing a porous amorphous silica-alumina refractory oxide is described in which a source of silica, such as tetra ethyl ortho silicate, in a non-aqueous solvent, such as an alcohol, is hydrolysed by adding an aqueous solution containing aluminum ions, in particular a solution of aluminum nitrate, thereby to form a sol and calcining the sol at, for example, 200.degree. C. to 600.degree. C. The product, which may have a microporous or mesoporous structure, is useful in the separation of fluids, especially the separation of carbon dioxide from natural gas.

摘要： An electrofusion coupler is slid over one of two thermoplastic pipes, each having a layer or layers of reinforcing fibers between the center of the wall of the pipe and the outside surface of the pipe. The end surfaces are trimmed in a butt fusion machine and the resulting end surfaces are forced against a heater plate. The plate is removed and the end surfaces are forced together. Internal and external beads involving inward and outward flow of material result, the outward flow ensures that there is at the welded joint an inner layer which is free from reinforcement fibers. The external bead is removed and the coupler is slid over the butt fused welded joint and energized to cause it to become fusion welded to the outside of the pipe.
