Patent DE-2734873-A1 (DE)
Title: Open=end rotor restoration - increases fibre collection groove dia. without changing relative alignment of adjacent surfaces
Inventor: STAHLECKER HANS
IPC: D01H4/10
Filed: 1977-08-03
Abstract: In the restoration of an open-end spinning rotor, the internal contours of the component are machined so that the fibre collection groove and its adjacent surfaces are structured to increase the dia. of the groove while the surfaces retain their relative angular pitch to each other. The process allows a used and worn open-end spinning rotor to be restored to usefulness without affecting the quality of the spun yarn.

Patent DE-2913237-A1 (DE)
Title: Electromagnetic counter with number wheels - has drive pawl with bounce control surface facing ratchet wheel
Inventor: HENDEL HORST ING GRAD
IPC: G06M1/04
Filed: 1979-04-03
Abstract: The design of the electromagnetic counter featuring number wheels (8) prevents pull-back of the ratchet wheel (3) during the return stroke of the drive pawl (1). The pull-back may occur when the guard pawl (7) is thrown-off during the high speed operation. The underside of the drive pawl (1) forms a bounce-controlling surface (9) set at an angle to the path of the pawl. When the guard pawl (7) is thrown by the forward stroke of drive pawl, it forces the control surface (9) into the engagement position for holding by gravity. The forced locking movement of the pawl (7) is, therefore, achieved without complicated methods which would make the unit more expensive.

Title: Digital frequency synthesiser - controls denominator of frequency divider and converts manual analog control signal into digital value for storing in memory
Inventor: MINAKUCHI HIROSHI
IPC: H03B19/00
Filed: 1979-05-17
Abstract: The synthesiser has a programmable frequency divider. A manual analog control signal is converted into a digital control signal and stored. The stored digital control signal is passed as an integer to the frequency divider. The magnitude of the difference between the analog control signal and the analog equivalent of the stored digital signal is formed. The memory is updated using the digital control signal depending on whether the difference determined previously exceeds a given magnitude. The advantage lies in the programming signal being kept constant regardless of slight or insignificant changes in the analog control signal. The synthesiser may be used in broadcast receivers or for controlling motors.
