Even spray appliance accessory - uses additional air supply into material flow in front of atomiser nozzle

Abstract: The accessory is for appliances using a material consisting of flowing solid particles. The spray material flow (12) leading to the atomizer nozzle (11) is supplied with an additional amount of compressed air directly in front of the nozzle. The air is taken via a branch pipe (14) with throttle (16) from the atomizer air feed (13) to the spray appliance (10). Alternately, the air may be supplied via a special feed having its own compressed air flow. The air system has an adjustable pressure control. A sinter material filter (17) is located between the branch pipe and the spray material flow.

Mobile feed unit giving even material flow

Abstract: The mobile unit evens out the flow of material, having a hopper below the level of its travel track to receive material in bulk dumped in it by lorries. A conveyor belt discharges the material from the hopper to successive sections of an opencast mining system, and particularly to sifting and crushing units of discharge conveyors. The hopper is an open-topped vessel (19) secured to the frame (18) supporting the conveyor belt (14), and which can be lowered below the level at which the lorry tips (2) into a previously prepared hollow (20) below the level of the travel track.

Apparatus for sorting contaminant material from processing material

Abstract: A contaminant sorting device for sorting contaminant material, such as metal and rocks, from processing materials, such as wood chips, comprising a housing having internal walls formed of a surface of revolution into which housing is fed processing material at the upper portion thereof, an impeller disposed in the housing for receiving processing material and propelling it radially outwardly against the inner surfaces of the housing walls, a plurality of vibration sensing devices disposed around the walls of the housing for sensing vibrations due to impingement of the processing material on the walls, an electrical circuit for distinguishing between signals generated in response to impact of the processing material from response to impact of contaminant material, a series of trap doors each associated with a corresponding vibration sensing device and disposed downstream in the material flow path for diverting from the normal flow path a portion of processing material containing contaminant material.

Automatic adaptive control of technical processes - involves sampling and analysing of output material and component flow is adjusted with delay due to process time lag

Abstract: The appts. (100) is used for a technological process such as cement making. The process produces an output material flow from input flows of materials of variable, or randomly fluctuating quality. Samples are taken from the material output flow and analysed, and their flow (kg/hour, m3/hour) is changed accordingly, so that output material flow parameters meet the specified requirements, or deviate from them only slightly. The best approximation of the output flow material is derived from the parameters of the input flow materials at the instant of their availability, and at instants preceding it. This approximation is obtained with a delay due to the process time lag. Input material flows are adjusted accordingly.
