Title: Short or long calling signal discriminator - is switchable to detect signals shorter or longer than reference
Inventor: STICHEL MANFRED
IPC: H04W88/02
Filed: 1979-03-20
Abstract: The mode of operation of a pulse width recognition circuit is determined by a 'short/long' switch. An example discriminates between calling signals with less or greater duration than 0.8s. The leading edge of the input signal trigers a time delay (monoflop) which opens a gate. When switched to 'short', if the trailing edge occurs during the gate, it generates a short output pulse. The output pulse duration is determined by the exponential decay of the trailing edge i.e. by a CR time constant. When switched to 'long', output is blocked during the time delay gate. If the input pulse ends after the time delay, its trailing edge triggers a second monoflop which delivers an output pulse with nominally the same duration as before.

Title: Stereophony system with artificial head and corrected earphones - has filter in each channel to cancel frequency response of artificial head
Inventor: LAMPARTER HELMUT DIPL ING
IPC: H04S1/00
Filed: 1979-08-09
Abstract: The stereophony system uses two microphones in the ears of an artificial head and reproduction by earphones to DIN 45500. These phones produce the same sound at the ears as would be received from a frequency independent loudspeaker a few metres in front of the listener. Thus the frequency response of the human head has been introduced twice; once by the artificial head and again by the phones. This defect is corrected by inserting a filter in each channel with a frequency response which is the inverse of that of the artificial head to sounds from the front. The filter consists of 3 bridged-T sections; 1 band-pass and 2 band-stops. It is entirely passive, using lumped L, C and R, and has an insertion loss of appr 37dB.

Title: Motor driven domestic ironing machine - has strain gauge strip attached to roller carrying arm to stop motor at excessive pressure
Inventor: SPRINGER REINER ING GRAD
IPC: D06F65/06
Filed: 1979-09-28
Abstract: Ironing machine with an ironing roller (2) rotated against a curved block (3), has the block supported by an arm (4) parallel with the roller axis, against which pressure is exerted during ironing. Along the arm is mounted a strain gauge strip (7) which is also subjected to pressure when pressure is applied to the arm, increasing its electrical resistance. This strip is incorporated in a resistance bridge. When the force applied to the arm is excessive, this resistance increases to a value which acts on the resistance bridge so that it operates a circuit which shuts off the motor. Instead of a single strip, two or more strain gauge strips can be used. Alternatively, a carbon strip or piezoelectric element can be used, or a pressure gauge.
