Title: Coke oven gas collection - using two mains at different pressures during charging and coking
IPC: C10B27/06
Filed: 1974-04-26
Abstract: A coke oven battery is fitted with a pair of gas collecting mains to which each chamber can be connected in turn. During the charging operation, every chamber is connected to the first main which is kept at a lower pressure. During the rest of the coking period, every chamber is connected to the second main which is held at a high pressure. This system can deal with the greatly increased gas flow rates during the charging operation without letting the gas escape through the oven doors. The dust laden gases can be treated separately. It eliminates the danger of air leakage through the door into the oven when a high suction is maintained after the charging operation.

Title: Mfr. of ammonium nitrate for artificial manure - by dilution with anhydrite produced by heating gypsum
IPC: C05C1/00
Filed: 1974-12-23
Abstract: Process and plant is intended for the mfr. of ammonium nitrate for use as an artificial manure. Pure ammonium nitrate contains 35% by wt. of nitrogen but for certain reasons the nitrate-based manure should have a nitrogen content of 20-34% of nitrogen. The redn. in concn. is obtd. by the addition of a filler consisting of calcium sulphate in the anhydrite form. After the addition the mixt. is granulated. The conc. ammonium nitrate is supplied to the plant through pipe and the pump to a tank situated in the upper portion of an expansion chamber of the granulation tower. The tank is provided with a heater and a mixer; it is connected at the base with a collector fitted with spraying nozzles. Finely divided gypsum is placed in the hopper with an automatic dosing device. The fan introduces air into the pipe; it passes over the heater. The heated air picks up gypsum and converts it into anhydrite on its way to the tank where it is mixed with the molten ammonium nitrate. The sprayed mixt. forms granules in the tower; these are collected at the base and conveyed to a bagging unit. The prod. obtd. has a satisfactory water content; it is less hygroscopic than a mixt. diluted with calcium carbonate as the filler.

Patent FR-2262821-A1 (FR)
Title: Electrostatic copying process and equipment - having improved contact between developer particles and surface carrying latent image
IPC: G03G15/08
Filed: 1975-02-26
Abstract: The electrostatic copying process is one in which a latent image is developed by a two component developer. It consists of passing the surface carrying the latent image past a rotatable roller at a distance which is a fraction greater than the diameter of the particles carrying the developer while simultaneously feeding the developer to the gap between the roller and the image-carrying surface. Preferably the roller is electrically conductive and connected to a voltage source to serve as developing electrode. In order to prevent damage of the image-carrying surface by particle agglomeration, the roller is flexible. By this process the developer particles are subjected to strong relative motion so that their contact with the image-carrier can be controllably increased.
