Title: Gear cutting machine tool - has play due to tool deflection eliminated by controlling tool pressure w.r.t. slide travel using fluid cylinder
Inventor: ERHARDT MANFRED
IPC: B23Q5/36
Filed: 1977-05-13
Abstract: In ordr to take up play due to an additional force is exerted on the cutter by means of hydraulic or pneumatic pressure cylinder.

Title: Echo compensation circuit for async. carrier system - gives rapid compensation for echoes with continuous or intermittent speech using Hilbert transformer
Inventor: HOEGE HARALD DR
IPC: H04B3/21
Filed: 1977-06-28
Abstract: A circuit is used for the compensation of echoes due to inadequate simulation in phantom circuits in a non-synchronous carrier frequency system. For adjustment of the frequency correction circuit a correction signal is derived from the output signal (y') of the adder through a regulating circuit which has an input connected to the adder output. The regulating circuit input signals are fed through a further adjusting element (D1) and also through a Hilbert transformer (H) followed by a further adjusting element (D2) directly and with a phase shift to the inputs of a further adder (101) whose output is fed to a subtraction circuit (111) to which the echo signal (y) from the phantom transformer (G) is also applied. The output from the subtraction unit is taken through an amplifier (K) to two multipliers (MU1m MU2) and there multiplied respectively by the signals at the input to the regulating circuit and at the output of the Hilbert transformer, the two output signals being fed to a pair of integrators (IN1, IN2) whose outputs control the adjusting elements (D1, D2).

Title: Control for self-propelled transportable pipe sprinkler system - has chassis frame formed from two swing arms connected with pipe line
Inventor: DAVIER RUDOLF VON DIPL ING
IPC: A01G25/09
Filed: 1977-11-08
