Abstract: ABSTRACT   The present invention provides apparatus for detecting and correcting errors in product codes of minimum distance 2t, with t being a positive integer, wherein, with respect to information of (kx?) symbols arranged in a matrix with k rows and ? columns, with k and ? being positive integers, in each of k rows a checksum symbol is added constituting codes with minimum distance 2 to ?, and in each of (?+1) columns including a column for said added checksum symbols, a set of parity check symbols are added constituting codes of minimum distance to k symbols.  The apparatus performs a first decoding of (?+1) codes in column-direction by means of a first decoder, then decides the decoding mode among three decoding modes by statistical processing of the error number flags issued from the first decoder, and finally performs a second decoding in which, responding to the decided decoding mode, the decoding is made as assertion of simple error detection, or single erasure error correction by using codes in row-direction, or error detection by using codes in row-direction.  The system is especially suited for use in parity checking in digital information data transmission or recording, where high speed and reliability are required.

Abstract: ABSTRACT                         BLIND FASTENER    A blind fastener for fastening an apertured workpiece of frangible material comprises a tubular body (12) having a shank (18) with a head (20) at one end and a tapering nose (22) at the other end, and means (14, 16) for forming a blind head by which the workpiece can be engaged at a position spaced radially from the shank (18) and clamped to the head (20).    The means for forming the blind head comprises a sleeve (16) and a headed bolt (14) whereby the sleeve (16) can be forced over the nose (22) of the body (12) and, thereby expanded.    A region (46) of the nose (22) immediately adjacent to the shank (18) is tapered at a sufficiently large angle to cause the leading portion of the sleeve to be permanently expanded to an internal diameter substantially greater than the external diameter of the shank, and the nose (22) has a less steeply tapered region (44) whereby the sleeve (16) is first radially expanded at a slower rate than by the region (46).  The tapering regions (44, 46) can each be frusto conical or can be provided by a continuous concavely curved surface.    The bolt (14) is in screw-threaded engagement with the body (12) so that, on rotation of the bolt; the sleeve (16) will be forced over the nose (22).          (Figure 1)

Abstract: IMPROVED NOISE BLANKING CIRCUIT AND METHOD        ABSTRACT OF THE DISCLOSURE          Noise blanking is provided by amplifying, limiting and detecting received signals.  The detected signals are compared with a threshold circuit.  The leading edge of each detected signal that rises at a rate greater than a selected rate to exceed an amplitude threshold level produces a blanking pulse of selected time duration.  Low as well as high level noise signals are blanked.  Slow rising information signals are not blanked, and fast rising information signals of high level are blanked initially for the selected time duration, but are not blanked thereafter.

Abstract: NADA DRUM AND ASSEMBLY                  ABSTRACT OF THE DISCLOSURE          A musical instrument having two drum heads of different size and tone quality, with a plurality of ten-sion straps used to vary the drum pitch of one or both of the drum heads during its operation.  The instrument is supported on a specially adapted stand with mechanical constricting means which allows the operator to constrict the drum tension straps by means of a foot pedal leaving the operator's hands free to play the two drum heads.  The tension straps are connected to a floating suspension ring which allows the drum operator to easily and quickly remove a damaged drum head should the drum head become defective during its operation, without the necessity of removing any of the drum tension straps.  The musical instrument may also be used by an operator separate from the drum stand, by means of a shoulder strap.  The use of a shoulder strap allows the drum operator to be ambulatory during the drums operation.  The operator can play the musical instrument drums either separately or together and vary their pitch by constricting the drum ten-sion straps by use of the operator's arm pressure instead of the mechanical means provided on the specially adapted drum stand.
