Title: High speed phase follow up control system - for laser interferometers with continuous recording of displacements in wide amplitude range generates difference current
Inventor: SMEETS GUENTER DIPL PHYS DR
IPC: G01N21/45
Filed: 1975-04-24
Abstract: A high-speed phase follow-up control system for laser interferometers, e.g. for user in dilatometers, refractometers, etc. has a recording unit with two photodetectors. The difference in current between the two detectors varies the change in a capacitor, and the capacitor voltage is fed back to the interferometer through a compensator. Pref. when the control system interference signals are produced using a polarised optical system. The control system enables for the first time optical displacements to be continuously recorded in an amplitude range from an Angstrom to several um at very high frequencies which can reach MHz in extreme cases.

Title: Laser boring or cutting of stone - subjected to ultrasonic or magnetostrictive vibration to increase cutting speed
Inventor: HANSCHMANN HORST
IPC: B28D1/22
Filed: 1975-05-21
Abstract: Stones or rocks are drilled or cut by a process using infrared lasers and magnetostrictive or ultrasonic crystal vibrators. The laser beam is automatically fed at uniform speed to and fro along a line on the stone, which is provided with ultrasonic transducers operating at a wavelength corresp. with the size of the crystals in the stone. The crystal structure os therefore vibrated while it is exposed to the laser beam. Optical fibres or waveguides are used to direct the laser beam, e.g. into a hole. Theuse of magnetostrictive or ultrasonic transducers permits an increased in the energy supplied by the laser beam, and therefore higher drilling or cutting speeds.

Title: Multistage phase modulation system - uses oscillator frequency controlled by variation signal with polarity changed against skin of preceding sub-signal
Inventor: GUANELLA GUSTAV DIPL ING DR
IPC: H04L27/227
Filed: 1976-10-06
Abstract: The multi-stage phase modulation system is for data transmission and ensures a clear assignment of the space phase of the indicator to the values of the modulating binary data signal. The variation signal is produced as the sum of subsignals which are derived from the multiplication of a unit signal, which has a time shift and extends over several timing intervals, with the individual pulse of a coded data signal. Amplitude and form of the subsignals are such that the phase change in one timing cycle is O, pi/4 or pi/2. If a data pulse deviates from the preceding one, a control pulse is produced and, after pulse shaping, a subsignal is generated which determines the sign of the variation signal. The polarity of the subsignal can be varied against the sign of the preceding subsignal depending on whether a subsignal was produced between them or not.
