Abstract: A receiver having a simple configuration for receiving and decoding digital broadcasts and outputting decoded data to an external device and moreover, decoding externally-input data and outputting decoded data to an external device. There are included a received-data demodulating device for receiving and demodulating digital broadcasts and generating a first clock in accordance with the digital broadcast and a clock generating device for generating a third clock by frequency-dividing a predetermined second clock. The first clock is used when the digital broadcast is received and decoded and the third clock is used when externally-inputted data is decoded.

Abstract: A device is disclosed for separating hard objects, such as stones, from a stream of wood in an apparatus for conveying or manipulating logs or blocks of wood including a conveyor section. The device includes a transducer disposed in a location suited for the detection of vibration. The transducer registers acoustic vibrations and is connected to a control unit by means of which hard objects conveyed along with the wood stream can be detected on the basis of the vibration signals they generate. The control unit is also used to control an exit gear incorporated in the conveyor section, so that hard objects which are detected will fall down from the stream of wood passing through the apparatus. The invention eliminates the need to build water-operated stone catchers as conventionally used for the removal of stones.

Abstract: Substantially pure peptides containing amino acid residues occurring in amyloid A protein and serum amyloid A protein are disclosed. The peptide compounds may be natural or synthetically derived. It is a characteristic feature of the peptides, regardless of their origin, that the sum of the hydrophilicity values of the respective amino acid residues is greater than or equal to zero. Moreover, specific antisera to these peptides are disclosed.
