Title: Method of distilling solid fuels
IPC: C10B7/00
Filed: 1927-10-07
Abstract: 278,740. Kulzinski, M. Oct. 7, 1926, [Convention date]. Coking processes.-A method of distilling solid fuels consists in conveying them, in layers permeable to gases, through a heating chamber or tunnel in which they are subjected to the action of a gaseous heating medium which contains an excess of steam. The hot gases circulate in a direction transverse to that of the movement of the fuel and are re-heated before re-entering the fuel, the distillation products and heating gases passing from one cross-section of the fuel to the next and thus heating the fuel throughout the length of the chamber. Fans or injectors are employed to cause circulation of the gases. Pipes may be provided for taking off distillates separately from various points in the chamber.

Title: Nuclear reactors cooled by pressurised coolant
Inventor: THURLBECK ARTHUR
IPC: G21D3/04
Filed: 1966-06-15
Abstract: 1,126,084. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 25 Aug., 1967 [15 June, 1966], No. 26779/66. Heading G6C. A coolant duct connecting with a reactor pressure vessel is provided with a counterflow brake to restrict the rate of escape of coolant from the vessel in the event of failure of the duct. The counterflow brake may be used in combination with other shut-off or flow restrictor devices and offers an extended time interval to introduce the other slower-acting devices. Even a factor of two reduction in the initial rate of depressurization of a gas-cooled reactor can be most advantageous from a reactor safety point of view. The main purpose of the invention is, however, to prevent instantaneous loss of coolant in the event of an inlet duct failure; this also precludes ingress of air into the reactor, and stagnation of the coolant flow. Avoidance of these hazards reduces the possibility of an exothermic graphite/air reaction and the number of failed fuel pins during the short period (100 Ásec.) immediately following the duct failure. In an integral reactor in which there are no main coolant duets outside the pressure vessel, counterflow brakes may profitably be included in the coolant service ducts, such as those required for coolant treatment.

Abstract: 503,336. Calcium cyanamide. AKT.-GES. FUR STICKSTOFFDUNGER. Oct. 4, 1937, No. 26821. Convention date, Oct. 2, 1936. [Class 1 (ii)] In the continuous production of calcium cyanamide by reacting calcium carbide of any desired fine granular size with nitrogen in the presence of an extender or diluent and with continuous movement of the reaction mass, the extender is added to the calcium carbide in a zone of the reaction space in which 'the reaction is proceeding vigorously and the quantity of the extender and its temperature are adapted to the reaction velocity so as to prevent undesired rise in temperature due to heat evolved by the reaction. The extender may be conveyed into the reaction zone together with the nitrogen for the reaction. Suitable extenders are calcium cyanamide, lime or magnesium oxide. Calcium carbide is supplied at one end of a revolving furnace 3 from a hopper 1 and the final product is discharged from the other end into a receiver 4. Nitrogen is introduced through a conduit 5 and a part thereof is compressed by a compressor 6 and supplied to a conduit 8, in part through a heating coil 7 arranged in the receiver 4 and in part through a byepass conduit 11. Calcium cyanamide is supplied from the receiver 4 to the conduit 8 by a bucket wheel 9 and is conveyed by the nitrogen and blown into the furnace through the upwardly inclined end 10 of the conduit 8. The surface over which the calcium cyanamide is distributed may be regulated by the inclination of the end 10 and the pressure of the gas. Specifications 393,128 and 461,274 are referred to.
