摘要： A coupling comprises a tubular insert (20), having an external shoulder (22) and external circumferential projections (26) separated by circumferential grooves (28, 30), and a tubular sleeve (14) having a largest internal diameter less than the external diameter of a pipe (10). The sleeve is advanced over the end (12) of the pipe and along the pipe away from the end. The pipe is constricted as the sleeve passes over it and then subsequently recovers to establish an end portion (18) which is unconstricted. The outside diameter of the insert is preferably not greater than the inner diameter of the pipe and the insert is inserted into the end portion of the pipe, the end of the pipe engaging the shoulder. The sleeve is then subjected to relative movement between said sleeve and said end until the end portion is gripped between the projections and the sleeve. The end of the sleeve preferably engages the shoulder (22). The coupling enables the pipe to be connected to other pipework.

摘要： Tin oxide sensors are made by mixing antimony bearing material with tin oxide powder and formation of the sensor by deposition of a slurry of the mixture onto a substrate and drying and sintering the slurry, the antimony bearing material being present in an amount sufficient to render the sensitivity of the sensor to one or more of the gases H2, CO, or CH4, relatively independent of the concentration of oxygen in the range PO2 10 - 1 atm. A further type of a tin oxide gas sensor is disclosed having a resistivity that at a measuring temperature increases with concentration of at least one gas to be measured, the sensor is made by calcining the tin oxide in air at a temperature in excess of 1400 DEG C, or otherwise treating the tin oxide so that it has a state of physical aggregation consistent with being formed in such manner. At a second measuring temperature the resistivity of the sensor to said one gas decreases with increasing gas concentration. The resistivity of the sensor is dependent on the concentration of several gases, the dependence at differing measuring temperatures being such that by measuring the resistivity of the sensor at several different measuring temperatures the composition of a gas to which the sensor is exposed may be calculated. An array of such tin oxide gas sensors may be mounted on a single substrate having heater means to maintain the sensors at differing temperatures. Such an array may also include an antimony bearing sensor as disclosed or other tin oxide sensors.

摘要： Apparatus for controlling a combustion system, particularly a fully-premixed burner combustion system, which incorporates a variable speed fan and means for supplying fuel at a variable rate of flow, the apparatus comprising means operable to vary the rotational speed of the fan progressively from zero to a maximum, means for measuring and storing the speed of the fan and means exposed to the flow of air from the fan for causing the operation of a switch mechanism when the rate of air flow generated by the fan reaches a nominated value, the control means being arranged to control the fuel supplying means so that it supplies fuel at one of a number of predetermined rates of flow and the fan so that it operates at one of a number of predetermined speeds, each fan speed corresponding to a particular predetermined value of the fuel flow rate, the control means being adapted to increase the speed of the fan from zero until the switch mechanism operates and to adjust each predermined fan speed with respect to its corresponding predetermined rate of fuel flow in the event that the fan speed causing the operation of the switch mechanism differs from a reference fan speed deemed suitable for that purpose, but to switch the fan off if the maximum fan speed is reached without the switch mechanism operating.

摘要： A steel service pipe (12) is connected to a main (10) by a tee (14). A flexible assembly (18) is inserted through the open end of the pipe (12) and through the tee (14) into the main (10). The flexible assembly includes a section of lower stiffness (22) and a ball and socket connection (24) of even lower stiffness at its leading end. The ball (30) is connected to a weight (34). The weight (34) falls down on entering the tee and creates a turning moment on the assembly (18). A plastic pipe (60) is inserted through the open end of the pipe (12) over the assembly (18) and is inserted through the tee (14) into the main (10). The pipe (60) has a corrugated leading end (64) which is more flexible than the remainder of the pipe (60) and has a tapered nose (64) terminating in a cylindrical mouth (66) which enters an aperture (70) in a liner (72) in the main (10).

摘要： An excavated opening (10) through a pavement (12) of a highway and through the underlying base material (14) to expose a gas main (16) is filled by (i) mixing on site cement, foaming agent and water to produce a fluid grout (26), (ii) mixing the grout with loose excavated spoil (22) in the opening, (iii) agitating the mixture using a hand-held poker vibrator (30), (iv) and repeating this procedure until the level (40) is reached. The level (40) corresponds to the underside of a protective layer (50) which is subsequently applied. The majority of the excavated loose spoil from the opening is reused.
