Abstract: A method and an apparatus for accurately weighing by a ladle weighing unit (2) of a metal melt in a ladle (3), in which the melt can be heated and stirred by power supplied by an induction coil (4). The induction field of the coil (4) is also applied to a coil weighing unit (1) so that the reaction force of the magnetic field influencing the melt is measured. In a weighing system (5), the net weight of melt is calculated by subtracting the signal of the coil weighing unit (1) from that of the ladle weighing unit (2). The weight change per time unit, which represents the mass flow rate of melt from the ladle, is calculated in the control system (6) and is used to control the pressure in the ladle in such a way the metal flow is kept constant.

Abstract: A method and apparatus of collecting a desired end-point weight amount of material first conveys the material into the collection container until a predetermined weight amount is collected. The predetermined weight amount is less than the desired end-point weight amount by a selected initial weight offset amount. An additional incremental amount of material is next conveyed into the container for a predetermined fixed time period. In doing so, the method and apparatus gauge the particular flow characteristics of the associated flow system. A further additional incremental amount of material is conveyed into the collection container for another time period, the length of which reflects the anticipated flow characteristics of the system, based upon the performance of the system during the preceding period. The method and apparatus repeat this sequence until the then-existing weight amount equals or exceeds the desired end-point weight amount.

Abstract: A weighing system is disclosed which operates in conjunction with a scale that has a trigger mechanism for terminating the flow of material into the scale's bucket. This system automatically periodically revises a tare signal stored in a latch circuit for combination with a weight signal to produce a net weight signal. The tare signal provides a measure of the residue stuck in the scale bucket. In an additional embodiment of the invention, a programmable controller is used as the means for periodically resetting the tare signal and is used to evaluate the final weight data to determine the average weight and the standard deviation of the weights. These determinations are used by the controller in combination with a predetermined weight to arrive at a computer setpoint signal for adjustment of the triggering of the flow termination so that the final weights will most closely approximate the predetermined weight.
Abstract: The apparatus of the invention comprises a fluent material-receiving chamber, and a frame from which the chamber is pendently supported. A load cell suspends the chamber from the frame, and transmits milli-volt signals to an electronic control and display assembly where the signals translate to display indicia representative of weights of fluent material received by the chamber. The assembly, in response to the signals, displays the achievement of a threshold of a fluent material reception level, which is selective and predetermined, to halt further admittance of fluent material into the chamber, and displays an actual fluent material reception level, by the weight of the material. Flexure stabilizers are intercoupled between the chamber and the frame, to inhibit any displacement of the chamber from its vertical, pendent suspension. The method of the invention sets forth the procedural steps, in weighing fluent material, capable of practice by the inventive apparatus.

Abstract: A web of flat polyethelene stock is drawn from a supply roll by a web feed mechanism, to be fed thereby up over a tube former then down, in tubular configuration, about a material fill pipe and then to and through pouch forming and weighing stations. A first spring biased nip roller, of the web feed mechanism, urges the flat polyethelene stock into engagement with one side of an appropriately powered drive roller, of the web feed mechanism, to effect the unreeling of the stock from the supply roll and to direct same up towards the tube former; while a second spring biased nip roller, of the web feed mechanism, urges the tubular stock into engagement with the other side of said drive roller to draw the stock down through said tube former and to and through said pouch forming and weighing stations.
Abstract: During the weighing operation, the change in weight indication is determined according to time value of elapsed time and this value is multiplied with the reduced shutoff time, the negative value thereof being added to the product of the square of the time change and a constant. The intended weight for the batch is added to the algebraic sum of the two values, and the further flow of substance into the receptacle wherein it is being weighed is terminated as soon as the weight indication has reached a summation value.
