摘要： Measurement of an integrated weight of a particulate material being continuously fed to a powder treating system or the like by providing a powder delivery port in a lower portion of a pressurized powder feed container for supplying the particulate material to a blowing port of the treating system, connecting a pressurized powder replenishing container to an upper portion of the powder feed container for replenishing the power feed container with the particulate material under pressure, continuously feeding the particulate material along with part of a pressurized carrier gas introduced into the delivery port of the pressurized powder feed container, communicating the powder replenishing and feed containers with each other with suitable timing for replenishing the particulate material, sequentially measuring the weights of powder contents in the containers to measure the integrated weight of the particulate material fed through the delivery port during a time period of operation; batchwise combining the weight of each powder replenishment from the replenishing container to the feed container to obtain the total weight of powder replenishment, subtracting the sum of the weights of momentary powder contents of the containers from the total weight of powder replenishment when the measurement is made in concurrence with a replenishing operation, and subtracting the weight of momentary powder content of the pressurized powder feed container from the total weight of powder replenishment when measurement is made at a time point falling outside the timer period for a replenishing operation.

摘要： The mass of an object dropped through a capacitive sensing transducer having a pair of spaced plates is determined independently of the spatial orientation of the object as it passes through the transducer, and independently of whether the object is entirely within the transducer at any instant. The transducer generates an output proportional to the instantaneous change in capacitance between the spaced plates caused by the sample passing therethrough. When the sample is a powder, the transducer output is integrated, and a correction factor is subtracted from the integral for correcting for temperature drift and for accumulation of minute particles of the powder on the plates. The spaced plates can be formed in a substantially 90.degree. twist; or, the transducer may be in the form of a plurality of pairs of spaced plates, each pair being oriented at a different angle with respect to the path of a sample through the transducer.

摘要： A scale for weighing material as it is transported along a movable conveyor is disclosed as including a pair of wheatstone bridge load cell assemblies which are mounted subjacent and across a roller assembly forming a part of the conveyor. The entire scale assembly is mounted between the framework stringers of the conveyor by a pair of inexpensive IPS pipes. In accordance with the invention, the entire scale assembly is mountable on differing width conveyor systems simply by changing the lengths of the IPS pipe portions of the scale framework so as to fit the frame on the respective stringers. Input into the dual wheatstone bridge circuits is fed into a computer, along with input relating to the speed (displacement) of conveyor movement to provide data needed for calculating a number of potential output figures. Remote display and monitoring of numerous such conveyor scales provides for ease of monitoring multiple conveyor systems.

摘要： A control for loss-in-weight feeders which decreases flow error during refill of the feeder hopper. The weight range (empty to full capacity) of the hopper is divided into weight increments. Samples are taken of the hopper weight during discharge and refill, and each sample is assigned to a weight increment. During discharge, a scale factor related to the density of material in the hopper is computed, assigned to a weight increment and stored in memory; and the hopper feed screw is driven at a speed proportional to the computed scale factor. During refill, the stored scale factors are retrieved from memory and the hopper feed screw is driven at a speed proportional to the stored scale factors; but no additional scale factors are calculated.

摘要： In a dynamic scale and a weighing method therefor, an object to be weighed is received on a weighing unit of the dynamic scale and weight information of the object on the weighing unit is detected by the weighing unit. The weight information includes a number of items of weight information, which are supplied to a processor, and a derived weight value is determined in the processor by evaluation of a predetermined number of the items of weight information, and a quality value for the derived weight value is also determined in the processor by evaluation of the predetermined number of items of weight information. Depending on the quality value, it is established, in the processor, that the derived weight value is a valid weight value and, when it is established that the derived weight value is a valid weight value, the weighing unit is then fed with a new object.

摘要： This invention relates to a weighing platform and a weighing system including such a weighing platform for dynamically weighing a flow of items while being conveyed over the weighing platform. The weighing platform includes one or more load sensors used in conjunction with two or more flat weighing sections adapted to be placed on the load sensors. A first support connects the adjacent ends of the two or more flat weighing sections so as to form a continuous 2-dimensional planar surface there between. A second support maintains the distal ends of the two or more weighing sections, when connected together via the first support, at fixed height so as to create a zero weighing sensitivity at the distal ends.

摘要： A method and an apparatus for dynamically check weighing objects (18a-c) that are guided across a weight-sensitive zone (14) of a weighing device (12) by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual measured weight values (E1, . . . , En) from which resulting weight values are derived in a digital evaluation unit (16) by calculating mean values. The evaluation unit (16) includes a plurality of cascading mean value filters (24a-e) that have different filter lengths which are varied by a common scaling value in accordance with a spatial dimension of the objects (18a-c).
