Abstract: 117,101. Keith, J., and Keith, G. May 29,1917. Blowpipe burners.-In a method of producing a high-temperature flame, more particularly for glass working, the combustible mixture is preheated whilst flowing through a straight passage with a smooth surface and of such form and dimensions that it is delivered in a non-turbulent condition. The preheating may be effected by a burner supplied with a portion of the combustible mixture or otherwise, or by electrical or other means. In the form shown in Fig. 1, air and gas supplied through B and C are mixed in a body D and heated in long narrow outlet tubes E, which may be of heat-resisting alloy, by annular burners H surrounding the tubes and supplied with a portion of the mixture. Regulating screws G control the supplies to the burners H, and the tubes E are provided with enlarged outlets in heads F screwed in a plate K which prevents combustion products from the burners H reaching the main burner flames. The tubes E may be bent to secure a fine adjustment of the position of the flame. Fig. 3 shows a unit adapted to be fitted into any form of burner. The preheating burner comprises a bush J extended to form a lantern carrying a disk L which replaces the plate K, Fig. 1.

IPC: G01N25/42
Filed: 1917-05-31
Abstract: 115,915. Simmance, J. F. May 31, 1917. Calorimeters. - In a recording constant-flow gas calorimeter, the gas is passed through a container so constructed and adjusted that the gas issues from the calorimeter burner orifice at a standard volume per unit time, notwithstanding changes of temperature and pressure and in the specific gravity of the gas. The governor or container W for controlling the quantity is constructed as described in Specification 27484/11. The burner X is connected to the pipe from the governor W by a ground-in joint Y to enable it to be swung out for lighting, a sliding outer tube on the burner being used to raise the flame into the calorimeter. The air supplied to the calorimeter is preferably extended with water . vapour as described in Specification 27920/12. A water-supply is connected through a pipe A to a small reservoir C, from which the water flows in three streams, (1) through perforations D in the air-saturating tube B down the inside of which the water flows into a tank, (2) to an overflow F, (3) to a pipe G leading to a box H containing the cold bulb b of the recording- thermometer. From the box H, the water flows through a chamber containing a constant-level overflow pipe U, and through a pipe J, from which it rises in an open head in a glass tube M and descends into the calorimeter, being then heated by the combustion of the gas on its way upwards to a third head at a level just below the calorimeter lid, whence it flows round the hot bulb c of the recording-thermometer to the outlet pipe K. A gas-meter R with a water-pressure gauge is arranged on a by-pass of the gas-supply tube 0, a cock T being provided so that the whole gas supply may be passed through the meter when desired, no gas passing through the meter when the cock T is opened. A cock S on the gas-supply tube' 0 is normally kept open by a suspended bucket kept full to overflowing from the wastepipe K, the bucket emptying itself through a hole in the bottom in case of failure of the water supply, so that the counterweight turns off the cock S and thus cuts off the gas supply.
