Patent DE-2656674-A1 (DE)
Title: Typewriter tabulator disengaging carriage stepping mechanism - has re-engagement lever adjustable to suit stepping pitch
Inventor: FUCHS HANS ING GRAD
IPC: B41J21/08
Filed: 1976-12-15
Abstract: In a typewriter tabulator, the rider abutment (21) is raised into alignment with the lowered riders (13) by raising of a control member (28) which disengages the carriage stepping mechanism. The control member is retained in the raised position by a latch (34). Engagement between the abutment and the rider moves a slide (9) on which the abutment is supported. This causes a lever (102) to release the latch and allow the control member to re-engage the stepping mechanism. The action of the lever is adjustable (104, 114) to suit machines of different stepping pitch.

Patent DE-2803102-A1 (DE)
Title: Automatic rF characteristic measurement or monitoring - supplies signal to be transmitted from four-pole input to A=D converter cyclically via frequency filters for digital signal derivation
Inventor: VOIGT KLAUS-CHRISTIAN DIPL ING
IPC: H04B3/46
Filed: 1978-01-25
Abstract: The process tests frequency characteristics of cables for broadcast programmes and senders during programme transmission. The signal to be transmitted is at the four-pole input cylically applied through frequency filters to an analogue-digital convertor which converts instantaneous signal level values in digital signals. These signals are transmitted through a separate channel to the four-pole output, and the output signal is similarly treated. The digital output signal is then compared with that obtained from the input processing so that instantaneous level differences at the four-pole input and output can be calculated.
