Abstract: A fiber blending system includes a number of feeders which dump fibers onto a conveyor. Each feeder includes a weigh pan into which fibers are fed. The weigh pan is pivotally mounted to the feeder and counterbalanced. Also connected to the weigh pan is a single load cell which monitors the weight of fibers in the pan. The load cell is connected to the weigh pan by a single wire about which vibration damping is disposed. Once a set weight of fibers has collected in the pan, feeding stops until a dump command is given related to the position of the conveyor. When the conveyor is in the appropriate position, all feeders then dump fibers at their respective set weights. The blending system is controllled by a programmable controller which monitors for three malfunctions. If fibers fail to dump after a dump command is given, if an excessive time occurs during which the pans are filling without reaching the set weight and when a predetermined number of heavy dumps occur, an alarm is generated.

Abstract: A printer used for a TV receiver, which printer comprises a memory for synchronously storing digital gradation density signals corresponding to the video signals in analog form received by the TV receiver; a read-out control circuit for reading out the digital signals stored in the memory; and a printer for printing out the signals read out by the read-out control circuit, thereby making copies of the images shown on the TV screen.

Abstract: A load sensor includes a scale cell for producing an output signal corresponding to the weight of an article, and a dummy cell, provided near the scale cell, for producing a noise signal output ascribable to floor vibration. A correcting circuit extracts a signal proportional to a DC component contained in the output signal of the scale cell and, on the basis of the extracted signal, corrects the output signal of the dummy cell to the noise level of a floor vibration component of the scale cell. The corrected dummy cell noise signal is added in opposite-phase relation to the scale cell output signal, so that the floor vibration noise contained in the scale cell output signal is cancelled out by the corrected noise signal of the dummy cell.

Abstract: A balance-type scale is provided which is made nearly substantially entirely of plastic, thereby being resistant to environmental degradation.

Abstract: Method of and apparatus for dosing powders by weight. To introduce a weight of powder with a predetermined final value P.sub.3 into a weighing receptacle, the functioning of mechanism for positively feeding the powder to the receptacle is controlled by a continuous comparison between the effective weight of powder received by the receptacle following an initial instant t.sub.0 and a theoretical weight conforming to an ideal evolution of such weight of powder as a function of time; at a final predetermined instant t.sub.2 with reference to the initial instant t.sub.0, the positive feeding mechanism is stopped and the powder remaining is allowed to run into the weighing receptacle in an amount corresponding to the amount of poweder which is lost during its transmission by the feeding mechanism.

Abstract: A computerized scale in which each weighing bucket is formed by two side-by-side compartments and by a single door which shuttles back and forth between two positions beneath the compartments. Each time the door changes positions, it closes one compartment to permit product to be dropped into and weighed in such compartment and, at the same time, opens the other compartment to permit previously weighed product to fall therefrom. As a result, one compartment is filled as the other compartment is being emptied so as to significantly increase the cycle rate of the scale.
