Title: Saw tooth wave generator for television line scanning - uses two switched capactive circuits for selected rise to fall time ratio
Inventor: BERGER HERMANN DR
IPC: H03K4/62
Filed: 1975-08-19
Abstract: A switching circuit provides a saw tooth waveform signal in an inductance for the line scan control of a television cathode ray tube. The inductance (1) is supplied alternatively from the positive pole (+V) and earth by two relays (2, 3) operated in a mutually exclusive switching mode from a gating circuit (4) triggered by a square wave input. The inductance is coupled over a common point (A) with two capacitors, one of 7 microfarads (5) and one of 1 microfarad. The sizing of the capacitors provides the ratio of rise to fall time of the saw tooth wave form, between square wave input signals (in this case 1:7). A slow time scan period is therefore generated followed by a fast return period.

Title: Twist grip throttle control for motorcycle - has gearing by planet gears for either fast or slow rotation of cable drum
Inventor: BRUDI HANS ING GRAD
IPC: B62K23/04
Filed: 1977-03-10
Abstract: The twist-grip throttle control for a motorcycle incorporates gearing so that the cable drum rotates either faster or more slowly than the manually actuated grip. The grip rotates relative to the handlebar (1) and is connected to a flange (4) with a pair of toothed planet wheels (5, 8). The planet wheels engage with the toothed inner surface of the fixed housing, and with a sun wheel (7) which drives the cable drum (12). The drum thus rotates faster than the grip. Alternatively, reduction gearing results from connecting the sun wheel to the grip and mounting the planet wheels on the cable drum. Respective applications permit full throttle opening with a single wrist movement, and sensitive throttle control.
