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.

The transmission and receiving of image information is effected by feeding a subject copy or a recording paper sheet by at least one paper feeding roller. The image reading/recording apparatus also functions as a copying machine by feeding the image information read from a subject copy by the reading portion directly to the recording portion.
Abstract: An apparatus for selectively printing either character signals or video signals received by a T.V. receiver on a printing medium wherein the character signals or the video signals are selectively transferred to a video memory prior to printing. This enables the transmission of data from a character decoder to be finished in one vertical period, and there is no need to stop the flow of images on the T.V. screen when they are printed.
Abstract: An image output apparatus prints an image of an original document and compares the printed image with the original document. Information representative of the original document operates a printing unit for printing an image of the original on a sheet of paper supplied from a paper feeding device. An image sensor senses the image on the printed paper and provides information representative thereof. The information from the image sensor is compared with the information supplied from the original document.

The digitizing means includes dither conversion means for dither-converting the image data and input means for inputting a signal to the dither conversion means to determine a parameter for dither conversion in accordance with a screen angle of the text image.
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. A counter-balance weight is of metal, but is embedded within the plastic. The scale is of two-part construction, comprising a body including the counter weight and a hook-like structure at the opposite end. A suspension member is pivotally connected to the body, and comprises a pair of spaced plates embracing the body. The suspension member includes a pointer, and the body is provided with indicia to be read opposite the pointer and readable directly in units of weight.
Abstract: An image reproducing apparatus wherein a halftone of an image is reproduced by repeating a picture element pattern composed of a plurality of dots as a unit and each dot display density of which is gradually controlled. The repetition of the same picture element patterns is avoided to improve tone reproducing performance.The image display unit includes a means for determining a disposition of dots composing a specific picture element pattern, i.e., display density of each dot in response to tone density of the original image, a means for comparing the disposition of dots of the specific picture element pattern determined by said means with a dot disposition or dispositions of one or plural surrounding picture element pattern or patterns, and a means for changing the dot disposition of said specific picture element pattern in the case when it is identical with dot dispositions of a predetermined number or more of surrounding picture element patterns.
Abstract: A system for detecting and measuring fast scan jitter having first and second photosensors combined in a unitary detector positionable in the path of a scanning beam; means for generating a packet of test pixels for modulating the scanning beam for jitter through a succession of scan lines; said first and second photosensors outputting signal pulses representing the intensity of said scanning beam following modulation by said test pixels; a differential integrator for integrating the signal pulse outputs of said first and second photosensors with one another to provide a test signal for each line scanned; a filter for smoothing said test signal, an amplifier for amplifying said test signal, a peak to peak detector for comparing the test signal of one scan line with the test signal from the succeeding scan lines to provide a jitter signal where said test signals are different; and a meter for converting said jitter signal to a visual readout.
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.
