Title: Speech processing system for hard of hearing - uses speech vocoder to generate synthetic speech with reduced information content for greater understanding
Inventor: ZOLLNER MANFRED DIPL ING
IPC: H04R25/00
Filed: 1980-04-25
Abstract: The speech processing system for those with extreme hearing defects is designed to reduce the information content of the signals without reducing the level of understanding. The acoustic signals to a microphone are received and converted into electric signals that are amplified before being transmitted to a filter chain that provides an input of a vocoder. Signals can alternatively be provided by a tape recorder. The filter chain has twelve stages in the range 225 Hz to 8.3 kHz. Signals are processed by a low pass stage coupled to a modulator coupled to a summing stage. The synthetic speech provided by the vocoder has a reduced information content and is generated as an output to earphones.

Title: Fish finger cutting press helping prevent finger breakage - with plunger face leaving air cushion between charges to prevent adhesion
Inventor: GROSS ERNST-PETER ING GRAD
IPC: A23P30/10
Filed: 1980-06-07
Abstract: Large blocks of frozen food (planks of frozen fish) are processed intermittently to smaller units (fish fingers) in multi-blade cutting presses. At the start of every stroke of the press, the preceding batch of smaller units is separated from the next large block by an air cushion. The press plunger face is fitted for this purpose with shallow slits to suit the cutter blade pattern so that the smaller units are advanced a little deeper before the next large block arrives. This prevents the fish fingers from adhering to the next block which used to cause an excessive mount of breakage of the fish fingers in irregular lengths, and therefore wastage.

Title: Examining right wave conducting cable transfer characteristics - using sinusoidally moving carriage with cable rollers during mechanical stress
Inventor: GIEHMANN LUTZ
IPC: G01M11/08
Filed: 1980-10-16
Abstract: The arrangement is used for examining the transfer characteristic of light wave conducting cable contg. one or more conductors in the presence of mechanical influences enable non-destructive testing which does not essentially alter the cable's mechanical characteristic. The mechanical influences, such as bending and torsion, act upon each individual conductor and can affect the transfer characteristic reversibly and irreversibly. The cable (1) passes around rollers on a moving carriage (3). The transfer characteristic is measured against the instantaneous position of the carriage. A reference light wave conductor is used to enable the formation of a quotient of the transfer characteristics. An autocorrelation coefficient is calculated using the transfer characteristic quotient. The speed of the carriage varies approx. sinusoidally.

Title: Striped coloured trim strip for automobiles - made by local coating of metal strip prior to applying extrusion coated sheath
Inventor: VOLLMER HEINZ
IPC: B29C48/08
Filed: 1980-12-20
Abstract: Coloured strip for decorative automobile body trim is made by transparent or coloured paste or liquid coatings to a strip of plain metal just before the metal strip is passed through an extrusion coating unit to apply a transparent protective sheath to the striped core strip. More versatile than assembly of contrasting prefabricated coloured strips into a prefabricated base profile with channels sized to receive the strips. The trim strip can have a relatively thin overall thickness, can be wrapped around relatively tight radius corners without cracking or delamination. Simpler than use of integral multiple stream extruders to produce composite multicolour tapes. The coloured layers are internal, which inhibits detachment and gives an appearance or depth and solidity.
