Title: Mosaic printing head with piezoelectric vibratory oscillator - has alternating potential superimposed on direct potential applied to oscillator
Inventor: DIBBERN UWE DIPL PHYS DR
IPC: B41J2/295
Filed: 1975-06-24
Abstract: Mosaic printing head for the dot-formation of printed symbols uses a piezoelectric vibratory oscillator to produce the printed symbol by impact on the recording surface. Even with the application of a relatively high direct potential e.g. 200V the printing force is limited and leads to a low density image. In order to increase the 'blackness' of the printed symbol an alternating potential is superimposed on the direct potential and has a frequency lying in the ultrasonic region. The oscillator is restored by applying a direct potential of the opposite polarity. The improvement in clarity is the result of the superimposed alternating potential increasing the force applied for printing.

Title: Shift arrangement in typewriter with rotary type head - has epicyclic gearing combining character selection and shift movements
Inventor: BRESSLEIN HELMUT ING GRAD
IPC: B41J7/60
Filed: 1975-09-05
Abstract: Typewriter with rotary type head has a character shift mechanism by which the head is turned through 180 deg. The head is mounted on a sun gear meshing with a planet gear meshing with an internally toothed segment. Rotation of head for ordinary character selection is affected by a rod connected to turn the segment about the axis of the head. The shift through 180 deg. is affected by a rod connected to turn a planet carrier thereby to orbit the planet gear relative to the segment. The mechanism sums the movements of the two rods, and the character selection and the shift movements can take place simultaneously.
