摘要： 458,995. Collecting and removing ashes &c. MACDONALD, J. A., 26, Victoria Street, Westminster. Aug. 17,1935, No. 23188. [Class 51 (i)] In a gas producer 1 having a restricted combustion zone adjacent a tuyere arranged in the aperture 3, ash and clinker are lowered upon a vertically adjustable plate 13 arranged beneath an opening in the producer bottom into a drawer arranged within an air-tight chamber 6 and comprising side plates and a back plate 11 to which is attached a horizontal extension 10 which, when the drawer is removed from the chamber 6 through the door 14, closes the opening in the bottom of the producer. The plate 13 is connected by pairs of pivoted links 29, 30 to nuts 25, 26 mounted on a handactuated spindle 20 provided with right- and left-handed threads by which the plate is raised and lowered. Specification 336,932, [Class 55 (i)], is referred to.

摘要： 226,001. Macdonald, J. A. Nov. 6, 1923. Wire resistances, embedded; mounted on grooved surfaces.-A water heater 1 is provided with one or more heating elements comprising a refractory non-conducting core having a plurality of longitudinal peripheral slots 8 containing a resistance, the elements being disposed in housings 6 readily removable from the heater. The resistance is preferably in the form of a ribbon disposed with one of its edges projecting outwardly so as to form fins on the core, and is secured in the slots by cement the setting of which is completed by sending a current through the resistance. The ends of the resistance are fused to the supply leads 12 and are then embedded in cement pressed into the groove 13 in the core. A filling of asbestos fibre renders the housing moisturetight. The junction box at the bottom of the heater is in two parts 18, 19 and contains the inlet elbow 5. A switch may be fitted in place of the cover plate 21, if desired.

摘要： 541,246. Gas-producers ; retorts ; furnaces. MACDONALD, J. A. May 16, 1940, No. 8795. [Classes 51 (i) and 55 (i)] In the partial or complete combustion of fuels with or without the recovery of by-products, a concentrated fire zone enclosed in fuel is obtained by a primary air supply of relatively low velocity, and a gas outlet of relatively high velocity, the outlet pipe being immersed in the fuel bed and means such as an annular pipe around the inlet pipe to supply steam or other vapour around the inner fire. The apparatus comprises a container 1 with an air inlet pipe 3 surrounded by a concentric inlet 3a, and a gas outlet pipe 5 which may be enclosed in a concentric outlet 5a, the flame being confined to an inner zone 6 and the hottest zone to 7. Approximate isothermals are denoted by 9 to 12. The extent to which the gas outlet pipe 5 projects into the fuel may be varied. Water is supplied by an inlet 5, and some of the gases generated may escape through outlets 13 near the top of the container. The hot zone is enclosed in an envelope of water vapour or other vapour or gases introduced through the annular pipe 3a. Specifications 336,932, [Class 55 (i)], and 480,392 are referred to.

摘要： 485,655. Gas producer plant. MACDONALD, J. A. Oct. 22, 1936, No. 28756. [Class 55 (i)] In a gas-producer, suitable for use with an internal-combustion engine, the ratio of the water to the air supplied to the producer is increased with the power demands on the engine whether or not engine suction on the producer increases. While the engine is running under light load, the comparatively high proportion of air to steam supplied to the producer establishes in the fuel bed a reserve of heat which is used to maintain the endothermic reaction taking place when an increased proportion of steam is supplied. A gas producer 1, preferably of the kind described in Specification 336,932, [Class 55 (i)], supplies gas to an engine 40 through a pipe 41 leading to a mixing chamber 44 to which air is admitted through an inlet 45 controlled by a valve 46, and from which chamber the mixture passes through a throttle valve 47 to the engine. The air inlet and throttle valve are controlled by an accelerator pedal 48, which, by links and levers 62, 60, 59, 56, also controls a drip feed 22 by which water from a tank 37 is supplied by a pipe 21 to a tuyere 5. A self closing flap valve 12 admits air to the producer under suction from the engine. A water jacket 7 for the nozzle 5 is provided with flow and return pipes 8, 9. The water from pipe 21 flows through passage 18 to an outlet 19 into the air supply. An arrangement by which water is supplied at an increased rate under heavy load comprises a link 81 attached to the accelerator lever 80, and operating through a dash-pot 82 a piston 84 in a cylinder 85 supplied with water through a pipe 86. Pressure on the pedal 48 injects through pipe 87 an additional supply of water to the fuel bed of the producer.
