摘要： A package burner has a fan rotatably driven at constant speed. Air from the surrounding atmosphere is induced by the fan through an open end of a conduit which guides the air to the fan from which the air is propelled down an outlet passage to mix as combustion air in a chamber with fuel gas from a gas supply nozzle so that flames issue from the chamber. A valve in the conduit or outlet passage can be set to regulate how much air is supplied as combustion air. A fluidic oscillator has an inlet open to the atmosphere and has an outlet open to the interior of the conduit. The observed frequency of the fluidic oscillator is a function of the flow rate of air through the fluidic oscillator and is also a function of the flow rate of air along the conduit. Therefore the measured frequency of the fluidic oscillator can be used to calculate the amount of combustion air being supplied along the conduit in unit time.

摘要： A method and kit is provided for temporarily blocking the bore of a pipe through which a fluid flows, the kit including an expansible flexible bag seal which is inserted through a hole provided in the wall of the pipe injecting into the bag seal. A quantity of a material adapted to expand in situ in the bag seal and inflate the bag seal to seal against the inside of the pipe is injected into the bag seal. The pipe may be a gas main and the material may be an expandable synthetic resin foam. The bag seal is removed by injecting thereinto a substance capable of dissolving the foam so that the bag seal can be at least partially deflated.

摘要： A motion transducer for measuring the displacement of, for example, shafts in gas control modules. The shaft 14 carries two magnets 10, 12 each of hollow cylindrical form, the magnet 10 presenting a south pole everywhere over its external cylindrical face and the magnet 12 presenting a north pole everywhere over its external cylindrical face. The shaft 14 moves vertically past an array of Hall-effect sensors 18-24 to produce sinusoidal voltage outputs at the sensors. The outputs are combined in a summing amplifier (FIG. 3). The combined output is not affected by rotation of the shaft and magnets nor by tilting or sideways displacement of the axis 16 of the shaft. That is because no matter what the rotational position is the sensors are always subjected to the same magnetic field and, if the shaft tilts or is displaced sideways an increased field at some sensors is compensated by a decreased field at others.(FIG. 1 is suggested as the accompanying drawing).

摘要： A pipeline inspection vehicle comprises a body 18 an electromagnet 20 for generating magnetic flux, and two foil packs 24, 26 for conducting the flux into and out of the pipewall 10. An array of defect sensors is arranged around the body 18, each sensor being mounted on a respective assembly 28. Each assembly 28 comprises a steel sledge 40 which runs along the pipewall and which is secured to a sensor housing 42. A length of belting 44 is sandwiched between the two and end portions form a leading member 46 and a trailing member 48 linking the sledge to the vehicle. Each assembly 28 is positioned against a spring 64 which is also positioned against the vehicle. The assembly collapses out of the way when the vehicle traverses a sharp bend and the foil pack 24 is deflected to the right. The two members 46 and 48 both counteract the force of the spring 64 when the sledge crosses a void in the pipewall. However, only the leading member 46 is effective during normal running of the sledge along the pipewall to transfer the motion of the vehicle to the sledge.

摘要： A vehicle 10 which inspects pipes 12 using flux-leakage has a flux generating electromagnet 14 and foils 18, 20 to transfer the flux to the pipewall 12. Sensors 22 detect flux forced to leak from the pipe by defects. The vehicle is required to pass 1-D bends as shown and has a swivel 40 having a load bar 48 on which there is a link 46 of a towing chain 26. On straight pipe the link 46 occupies a first position nearer to the axis 44. In a bend the swivel turns so that the link 46 can slide along the load bar 48 to a second position further from the axis 44. This reduces the angle which the chain 26 makes with the axis 44 and jamming of the vehicle 10 in the bend is avoided.

摘要： An acoustic wave energy generator comprises a body having an internal gas-pressurisable first chamber 1 adjoining a second chamber 2 into which a liquid is introduced to cover a vibratable means 4 which may be a flexible diaphragm and is mounted on the second chamber so as to close an associated opening 5 in the second chamber. After the first chamber 1 is pressurised with a first gas a common closed opening between the chambers is opened to cause communication between the chambers 1,2 to permit a shock wave emanating from the first chamber to impinge on the liquid. As a result, the vibratable means 4 is caused to vibrate so as to produce acoustic wave energy in response to the impingement of the shock wave on the liquid. By using different liquids and/or different heights of liquids in the second chamber the generator may be tuned to provide acoustic wave energy with a relatively narrow chosen frequency range or within a chosen substantially single frequency.

摘要： To detect escape or spillage of a cold liquid, for example liquefied natural gas, a narrow, robust, flexible, resilient, plastics tube, placed where the escaped or spilled cold liquid can contact it, is filled with carbon dioxide gas from a gas supply via a non-return valve and a pressure regulator which ensures that the maximum pressure in the tube is at a desired value which is preferably greater than the pressure of the ambient atmosphere surrounding the tube. A gas pressure drop detector is provided to observe a pressure drop in tube. Should escaped liquefied natural gas contact the tube the latter is so cooled that the carbon dioxide gas inside de-sublimates to a solid of greatly reduced volume causing a marked drop in pressure in the tube. This is observed by the pressure drop detector which initiates a warning or some safety action. A gas flow restrictor ensures the gas supply cannot rapidly re-charge the tube before the pressure drop detector has responded to the pressure drop.

摘要： An electro-fusion fitting (10) includes a body (12) of thermoplastics e.g. polyethylene, with a heater element (14) connected to heater terminals (16, 18) and identification devices (60, 62) moulded in the body (12). The devices are connected to the heater terminals and to identification terminals (20, 22). A control unit (24) connects a reference voltage (74) in turn to the device (60) and then to the device (62). In each case the device forms a voltage divider with a resistance (80) so that the value of the device is found. The two values identify the fitting so that the time the element (14) is energized can be set automatically by the unit (24) for each different size or kind of fitting. Neither device is required to be a specially accurate component and the range of values of the devices is less than it would be for a given range of fittings if only one device was used per fitting.
