Abstract: A signal detection apparatus wherein pulses of the reverse polarity to that of the signal pulse to be detected are detected from an input pulse signal, and thereafter the signal outputting path is cut off for a fixed period, so that noise pulses which have oscillating waveforms in both positive and negative polarites are segregated from the signal pulses which can be provided with a unipolarity, by making use of the difference in polarity, and thereby, the noise pulses are eliminated regardless of their pulse heights. Further, the signal input to the cut-off circuit is delayed for a fixed period of time so that the first peak of the noise pulses may be eliminated even if it is of the same polarity as that of the signal pulse.

Abstract: In a method and a device for assortment of objects a broadbanded light is emitted from a light source, which light is reflected via a rotary mirror against the objects falling freely immediately after they have left a conveyor belt. The reflected light is led via the other part of the same surface of the rotary mirror to an optical unit and is reflected against a double detector dividing the light flow into two wide ranges about 1 .mu.m. The detector signals are compared to one another and after processing the resulting signal is caused to actuate means separating the objects mechanically.

Abstract: A controller for a Chinese character printer, or the like, includes a pattern buffer into which character pattern data is written by an input control unit transferring the character pattern data from a temporary input buffer. The character pattern data is transferred from the character pattern buffer into a font memory by an output control unit only during a non-printing period, such as during a paper feed, of the printer. Print data, including character codes, are transferred by the input control unit from the input buffer to a page buffer. During a printing period, the output control unit selects character pattern data in the font memory in accordance with the character codes in the page buffer and transfers the corresponding character pattern data to a pattern converting unit which sends appropriate print signal data based on the character pattern data to the printer.

Abstract: A process for producing center-filled food products comprises forming a hollow cylindrical shell of edible material having a single continuous longitudinal slit. The shell is conditioned until it is able to maintain its hollow, cylindrical shape and longitudinal slit without external support, and may subsequently be dried to a shelf stable moisture content. The shell is then filled through the longitudinal slit with an edible food substance which is substantially stable at product storage temperatures. The shell may then be cut to final product size, externally coated with seasoning, and packaged.
