Title: Process and apparatus for dewatering low-grade coal
Inventor: ELMORE CARL LAYMAN
IPC: C10F5/00
Filed: 1984-02-21
Abstract: A process and an apparatus for dewatering low-grade coal, for example brown coal, by steam drying or by hot water drying is carried out in such a manner that brown coal is first comminuted to a particle size of less than about 10 cm and is preheated by steam. The particles are then entrained in a liquid and introduced into a high pressure loader from which they are fed into a high pressure circulation loop and supplied to a liquid/particle separator at the top end of a vertical vessel. The particles entering at the top end of the vessel are contacted with saturated steam or hot water (for example 250-260 DEG C) in counter-current. The particles are finally rinsed in counter-current at the bottom end of a vessel. A slurry of liquid and particles leaving the bottom of the vessel after the rinsing is introduced at a considerably reduced pressure into a second high pressure loader and transferred to a low pressure loop. The liquid and the particles in the low pressure loop are separated and then subjected to an evaporative cooling, in order to result in a dewatered, dry, low-grade coal.

Title: Practice method for indirectly-firing weapons, and a casing for carrying out the method
Inventor: WEIBULL JOHN LORENS
IPC: F41G3/26
Filed: 1986-05-31
Abstract: In the case of a method for practice firing with indirectly-firing weapons, a case (5) is used which has the same external shape and size as the normal cartridge case of the weapon and contains an insert (13) which is independent of the weapon calibre with partly a unit charge for firing the insert and partly a charge for detonation marking. The insert is fired by means of the normal weapon firing mechanism, and its detonation marking is observed. The actual setting change is then carried out either by using a special table or the like which is determined especially for the insert and the unit charge in order to convert the observed erroneous position of the detonation marking into those values which are required in order to change the setting of the weapon in azimuth and elevation to the normal azimuth and elevation setting scales of the weapon, or using the normal table or the like for the weapon for converting the observed, erroneous position of the detonation marking into those values which are required in order to change the setting of the weapon in azimuth and elevation to azimuth and elevation setting scales which are determined especially for the insert and the unit charge as well as the weapon. A case for carrying out the method has the same shape and size as the normal cartridge case of the weapon and contains an insert (13) which is independent of the weapon calibre with partly a unit charge...
