Abstract: 1452477 Hydrogen rich reducing gas URQUHART ENG CO Ltd 18 Oct 1973 [27 Oct 1972] 49784/72 Heading C5E A reducing gas mixture rich in hydrogen is produced by the partial combustion of hydrocarbon gases, e.g. natural gas, methane, propane and butane, or ammonia, or mixtures thereof, by injecting the gas to be burnt into the combustion chamber of a refractory lined combustion chamber in admixture with a substoichiometric quantity of air, directing the mixture initially along a surface of the refractory lining, burning the gas in the chamber, reversing the direction of flow in the chamber and establishing a recirculation of gases within the chamber to promote rapid admixture with the incoming gas and air mixture and create a temperature profile within the chamber which promotes combustion of the incoming gas and substantially avoids the formation of free carbon from hydrocarbon gas, and discharging the combustion products from the chamber as a reducing mixture rich in hydrogen. The gas is supplied from outside the chamber at sufficiently high velocity that it entrains the air for combustion during passage into the chamber. The air may be preheated before it is entrained. Apparatus for carrying out the process comprises a refractory lined, substantially cylindrical combustion chamber 1 having a front wall 2, an exit duct 6 in the front wall for discharge of combustion products from the chamber and a rear wall 4 opposed to the front wall, and a plurality of jet nozzles or burners 7 arranged in the front wall to inject into the chamber a hydrocarbon gas or ammonia or mixtures thereof in admixture with a sub-stoichiometric quantity of air such that the mixture of gas and air flows along the refractory lining towards the rear wall at sufficient velocity to entrain combustion products and establish a recirculatory flow pattern within the combustion chamber. The chamber includes an outer jacket 8 spaced from and surrounding the refractory lining 5 to constitute an air duct 9 through which the air is caused to flow to the jet nozzles 7 whereby the air is preheated. Duct 10 supplies a plurality of supply jets 11 to discharge high velocity streams of gas into jet nozzles 7 to entrain air from the duct 9 and mix therewith during passage through the nozzles into the chamber.

Abstract: 1300453 Protective arrangements NOVOCHERKASSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI POLITEKHNICHESKY INSTITUT IMENI SERGO ORDZHONIKIDZE 5 Nov 1970 52616/70 Heading H2K  In a differential protective system in which the currents to and from a protected alternating current arrangement 1 are summed to energize a differential starting element 5. the sum of these currents during the times they have one polarity and the sum of these currents during the times they have the opposite polarity are applied to relays 7 and 8 respectively to produce output signals when the sums exceed a predetermined value. When under external fault conditions the two output signals are simultaneously present during the first cycle of the fault, they cause a signal to inhibit the action of the element 5. In the arrangement shown, under external fault conditions, the output signals from the relays 7 and 8 are applied to an AND gate 11 which provides a signal to an INHIBIT gate 15. At the same time an OR gate 12 supplies a signal to a slow-to-reset relay 13 which supplies output signals to a slow-to-operate relay 14 and a NOR gate 16. The INHIBIT gate 15 supplies a signal to a memory circuit 17 until the operation of the relay 14 causes the gate 15 to cease to pass the output signal from the AND gate 11. The memory circuit 17 provides a signal to cause an INHIBIT gate 6 to block any output from the element 5. The NOR gate 16 provides a signal to restore the memory circuit 17 when the fault is cleared. In the event of an internal fault, the AND gate 11 does not initially provide an output signal, the fault currents all having the same initial polarity. Hence there is no output signal from the gate 11 to pass through the gate 15 to the memory circuit 17 before the relay 14 operates to cause the gate 15 to assume its inhibiting action. So the memory circuit 17 provides no signal to the gate 6 and the signal from the differential element 5 passes through the gate 6 to effect the disconnection of the protected arrangement.
