Title: Measuring mean grey scale value of reflecting surface - using matrix of narrow prisms with sources and receivers
Inventor: HERWIG THOMAS DIPL PHYS
IPC: B41F33/00
Filed: 1980-03-13
Abstract: An optical arrangement measuring the average grey value of a reflective surface has a receiver for only that light from a source which is diffusely reflected from the surface which is divided into a matrix of narrow rectangular partial surfaces. The problems of low intensity and uniform illumination are overcome without necessitating the use of focussing elements. A prismatic optical conductor (3) is placed over each partial measurement surface (2) so that its plane parallel base and top each have a side perpendicular to the longer partial surface (2) side. The base and cover surfaces are internally mirrored. The parallel trapezoidal sides of the prism are internally coated with light absorbing material. A light source (4) and receiver (5) are placed on the side of the prism remote from the partial surface so that light cannot be directly reflected to the receiver.

Title: Three=phase rectifier circuit for motor supply - has zero transitions of phase-shifted voltages for thyristor firing synchronisation
Inventor: TRUEMPLER WALTER ING GRAD
IPC: H02M7/155
Filed: 1980-07-17
Abstract: The rectifier uses controlled thyristors (TT1,TT2,...TR1,TR2) coupled in pairs, each associated with a respective phase of the 3-phase network. The firing synchronisation of the thyristors (TT1,TT2, TR1,TR2) is ensured by the zero transitional of synchronisation voltages instead of the zero transitions of the voltages applied directly to the thyristors (TT1,TT2, TR1,TR2). These synchronisation voltages are obtained by phase-shifting preceding voltages obtained from the voltage system by a given phase shift, eg. 60 degrees. The thyristors (TT1,TS1, TR1) for all three phases which are coupled together at their cathodes, are synchronised with the positive zero transitions of the synchronisation voltage and the thyristors (TT2,TS2,TR2) coupled by the anodes are synchronised with the negative zero transitions. The rectification is independent of the direction of the rotating field.

Title: Flavoured jam
Inventor: KRETZSCHMAR RUEDIGER
IPC: A23L21/12
Filed: 1982-01-28
Abstract: To improve and vary the flavour of jams, in particular made of cherries, morello cherries, strawberries, red/blackcurrants and blueberries, and thus to satisfy a hitherto unsatisfied consumer potential, a natural or artificial aroma concentrate with a flavour type other than the jam in question, such as rum, arak and others, is added to the jam. The addition of the flavouring takes place before dividing the batch into portions and can be varied relative to a certain amount of jam, which, in turn, allows a further differentiation to be obtained by various levels of flavouring concentrate.
Patent DE-3205905-A1 (DE)
Title: Watercraft
Inventor: NOWOTNY WILLY
IPC: B63B35/73
Filed: 1982-02-19
Abstract: The novel watercraft is specifically intended for play and sport on water, with which a novel type of leisure activity is to come into being. For this purpose, the rower is arranged to sit in the forward seating direction, i.e. in the straddling position, on the floating body, in contrast to conventional boats. The floating body conveniently consists of two closed, symmetrically produced hollow bodies which are assembled in a suitable manner to form a floating body. As the schematic representation shows, the floating body (1) is boat-shaped in the lower part and is open from below over its entire length in such a way that a so-called water shaft (2) results in which the oar (3) serving for propulsion is arranged. The oar (3) functions as a one-armed lever with fulcrum (4) which the person seated on the floating body actuates in the direction of propulsion by pressing it forward (a) and pulling it towards himself (b). The water shaft also enables other drive means suitable for propulsion to be arranged instead of the oar. In practice, the floating body will be given a more pleasing form than shown here schematically. <IMAGE>
