Abstract: The apparatus has a plurality of fluent-material-receiving chambers arrayed about a central, vertical pipe, and each chamber has a load beam extending therefrom. Gusset-type brackets, projecting from the pipe have slotted limbs through which the load beams pass, and opposite end of the load beams are coupled to load cells. Also, steel flexures are interposed between the limbs and the load beams pivotably to support the load beams thereon. Each beam has a counterweight fixed thereto, such counterweights being of weights which counterbalance the summed weight of its associated chamber and such components which are fixed to said chamber. Hence, weights of fluent materials introduced into the chambers can be directly read without there being a need to discount the chamber and components weight. Auger-type conveyors are provided for conducting fluent materials from each of the chambers to a blending tank. The latter has a mixing wand therein which is motor-driven to thoroughly mix the tank contents.

Abstract: A mechanical process for filling the tubes (3) of tubular reactors with granular solids, e.g. catalysts, wherein two or more streams of material, e.g. of different catalytic activity, can be introduced in a controlled manner into each tube (3) which is to be filled, from two or more stock vessels (1,2) via two or more dispensing devices (MI, MZ) mounted above the upper tube end plate (13). By this process, different thermal/catalytic reaction profiles can be achieved over the length of the tube, or in certain groups of tubes within the tubular reactor, with substantially less time being required for filling the tubes (3).

Abstract: An apparatus for monitoring the blend of fibers being dropped onto a receiver by a plurality of weigh pans responsive to predetermined weights of the fibers being accumulated in the respective weigh pans. An electrical signal is produced when predetermined weights of fibers are loaded into the weigh pans. Each of the weigh pans is equipped with a monitoring circuit which includes load cells operably connected to respective weigh pans which generate an analog signal indicating the weight of the fibers accumulated in the weigh pan. An analog to digital converter converts the analog signal and responsive to being triggered is fed into a latch circuit that is triggered by the electrical signal produced when all of the hoppers are full. A digital to analog converter is connected to the latch circuit and converts the digital signal back to an analog signal that is recorded on a chart recorder.

Abstract: Control for a multiple batch process for preparing product from a plurality of constituent ingredients, in which an error in one batch from the multiple batch is equally divided over the subsequent batches so that all of the remaining portion of the multiple batch can be used and the resulting product is uniform. In the process of preparing product from a plurality of constituent ingredients, a batch of certain of such ingredients is mixed in a receptacle, sequentially divided into substantially equal portions and transported to an apparatus for combination with certain other of such ingredients for preparing the product. The error compensating control comprises an intermediate chamber in flow communication with the receptacle and the apparatus. A predetermined portion of the mixed batch is transferred from the receptacle to the intermediate chamber, where it is weighed, and then delivered to the apparatus.

Abstract: Apparatus and process are provided for weight-blending two or more constituents on a continuous basis. In operation, the constituents are sequentially added to a weight-measuring tank connected to a weight scale with an indicator which undergoes excursion between sensors positions. The scale face has an indicator which undergoes excursion between position sensors, such as electric eyes. When the system is electrically activated, a first position sensor detects zero weight from the measuring tank and remotely calls for the pumping of the first constituent, which continues until the indicator in excursion reaches a second position indicator.

Abstract: An improved system and method is disclosed for compounding batches of a plurality of constituents in accordance with a predetermined formula. The individual batch constituents are sequentially fed into a batch receiving hopper. Feeding of each constituent is controlled in response to the current weight of the constituent in the hopper and the current rate at which the constituent is being fed. Preferably, feeding is accomplished at a plurality of decreasing rates with the fastest rate maintained for a maximum time to minimize the total time required to compound the batch.

Abstract: Fine-grain fuel is delivered from pressure vessels with a vehicle gas as a fluidized flow into a reactor for gasification at an elevated pressure. A gaseous gasification agent is also fed into the reactor. A control system for the fine-grain fuel and gasification agent includes detectors to provide an electrical signal which varies during feeding of fuel from the pressure vessels into the reactor. Controllers produce a fuel rate control signal corresponding to a comparison between the electrical signal from the detectors and a predetermined reference value corresponding to the desired fuel supply rate. Control valves respond to the fuel rate control signal to adjust the supply of vehicle gas to transfer fuel from the pressure vessels into the reactor.
