Title: Hydraulically actuated tube expander - uses piston with tapered skirt to connect expander to hydraulic ram
Inventor: WIEDENHOFF WOLFGANG DIPL ING
IPC: B21D39/20
Filed: 1979-02-19
Abstract: A tube expander consists of a number of segments (2) fitted around a tapered sleeve (1) of polygonal cross-section. The tapered sleeve (1) is attached to the piston rod (3) of a hydraulic ram by means of a thick walled sleeve (7) with a tapered bore (15) running into a cylindricl recess (11).

Title: Integrated amplifier for telephony - has AC output impedance increased by eliminating DC component of positive feedback signal
Inventor: GUTSCHE BERNHARD DIPL ING
IPC: H03F3/187
Filed: 1979-06-02
Abstract: The integrated amplifier is matched to the telephone network and has a wide drive range using few components. The amplifier's a.c. output impedance is increased compared to the differential impedance corresponding to the intermediate voltage output characteristics in the linear range. This increase is achieved by passing a positive feedback signal - obtained from a resistor - via a current mirror to the drive point of the output stage. A compensation signal is obtained from a point supplying the input stages and passed via two further current mirrors to the output stage's drive point in order to suppress the d.c. component of the positive feedback signal.

Title: Siren for burglar alarm - has self-contained battery and sounds when charging supply is turned off
Inventor: LANDKAMMER FRANZ JOSEF DR
IPC: G08B3/10
Filed: 1979-07-27
Abstract: The siren of a burglar alarm consists of a loudspeaker driven by an oscillator and powered by a storage battery. The battery is charged by a supply from the alarm system and the alarm is given by switching the supply off. The charging supply is regulated by a series resistor and shunt Zener diode, and connected to the battery via another diode. The oscillator is connected to the battery by a transistor pair. The transistors are normally held off by the Zener voltage through an inverting circuit, and conduct when the supply fails. A capacitor, which has been charged via a diode to the Zener voltage, slowly discharges through a resistor. When the voltage falls low enough to open an AND-gate in the inverting circuit e.g. after 1 minute, the transistors are turned off again.

Title: Circuit for image signal conversion - uses commands to information signal adaptor for tapping ambience dependent level values for programmed evaluation
Inventor: FRYEN JUERGEN DIPL ING
IPC: H04N5/33
Filed: 1980-06-27
Abstract: The conversion concerns image signals from a thermal image sensor to video signals for a conventional image display. The signals of a thermo-sensor, in functional connection with a clock pulse generator, are supplied to an information signal adaptor via an amplitude discriminator. The latter which is affected by the clock pulse generator and applicable commands, transmits its output signals as a video signals most suitable for human optical perception, also via a clock pulse generator for energising a signal matching stage. The commands supplied to the information adaptor can be programmed for derivation of ambient level values of the thermo-sensor images. This is followed by an evaluation of a series of several individual images with changing image portions. Preferably the information adaptor contains microprocessors for command controlled image portion evaluation. The matching processes may use previously determined and stored process values.
