Abstract: 1405230 Candles J CANGARDEL 28 Dec 1973 [8 March 1973] 60024/73 Heading C5W A candle which burns with a coloured flame comprises a central rod of pure metaldehyde embedded in a body of stearin or stearin acid 5-15% by vol. of a metal stearate to give the desired colour. Green, red and yellow flames are given by Cu, Li and Na stearates respectively, and a blue flame from the metaldehyde in the absence of stearate; composite colours can be obtained by mixing stearates. The illustrated candle has a central square metaldehyde rod 1 embedded in body 2. To ensure uniform burning a cup-like member 3 is provided at the top of the candle, the member comprising conical downwardly sloping collar 4, whose outer edge 5 may extend 1-2 mm. beyond the periphery of the candle, and central cylindrical sleeve 6 which can slide and be guided along vertical edges 7 of rod 1. Member 3 may be of copper, brass or aluminium. Thus member 3, when heated by flame 8, melts and penetrates into body 2 and in each of spaces 9 between a surface of rod 1 and collar 6 the mixture of melting stearate accumulates in contact with rod 9 is vaporized by the base of flame 8. At the same time sleeve 6 is guided on the vertical edges 7 of rod 1, the melting-point of which is 380 C. Thus rod 1 is always solid adjacent sleeve 6 and member 3 is guided by the rod so that edge 5 of 3 is always horizontal.

Title: Internal Combustion Engine Utilising Liquefied Gaseous Fuel
IPC: F02D41/00
Filed: 1979-01-15
Abstract: An air/fuel supply system for an internal combustion engine using liquefied gaseous fuel comprises a solenoid operated fuel injector 18 which injects a controlled quantity of the fuel in a liquid state into a mixing region 26 of the induction system. A control system monitors the cooling effect of the vapourising fuel by measuring the temperature difference between a pair of temperature sensors 44, 46, respectively upstream and downstream of the mixing region and compares the measured temperature difference against a preset reference level to derive an error signal. The error signal is applied to control the fuel injector and regulate the fuel supply to maintain the temperature difference and thus the air/fuel mixture ratio constant. The reference level may be adjusted by monitoring other parameters or operating characteristics e.g. intake air humidity, exhaust gas composition or firing voltage values, to determine and hold the optimum setting of the air/fuel ratio. <IMAGE>
