Patent DE-2349445-A1 (DE)
Title: Temp. regulator and overload protection system - has PTC thermistor and melting fuse allowing spring contacts to open if thermistor fails
Inventor: MORGAN JOHN MYRDDIN
IPC: H01H37/76
Filed: 1973-10-02
Abstract: The temperature regulator and overload protection system has a PTC thermistor to regulate the current supply and to prevent overloads. A mechanical device is employed to protect the circuitry against overloading if the thermistor itself fails. The mechanical device consists of a fuse body that under normal, non-overload conditions, i.e. under conditions that the thermistor can handle if it is working properly holds two spring contacts together. If the thermistor fails so that the temperature rises without restrained, the fuse body melts and the spring contacts separate. One contact is formed by a spring ring with bent ends surrounding the fuse boyd and spring urged against the other contact.
Patent DE-2349868-A1 (DE)
Title: Electronic multistage coded key - with semiconductor circuit actuated by input pulses has capacitor for erasing of actuating capability after time lapse
Inventor: KROP HEINZ
IPC: G07C9/00
Filed: 1973-10-04
Abstract: On applying an input pulse a circuit produces an output signal when the individual circuits are actuated in a previously specified sequence or by electronic means. The coding stage of this kind is available for actuation only for a certain period after actuation. After this time has elapsed a relevant actuating pulse does not produce any results. This means that the actuating capability is automatically erased. Only the first code stage is excepted and can be actuated at any time. This arrangement ensures that the electronically actuated key code cannot be broken by repeated testing. Each coding stage consists of only one transistor together with the associated base and collector resistors and coupling capacitor which is connected between the collector of the previous stage and the base. No transistor is used in the first stage. The last stage is connected to a power transistor for reliable releasing of the locking solenoid.

Title: Locking device for railway lines preventing them from cross-movement - consists of steel fixture placed between two sleepers at right angles to the rail foot
Inventor: KLOTZ WALTER
IPC: E01B13/00
Filed: 1973-12-10
Abstract: The locking device is made up of metal sections welded together, and hooks over one edge of the rail foot, and extends almost to the other rail foot edge, where it bends downwards at right angles for a short distance.

Title: Microwave transmitter system has oscillator frequency modulated - by varactor to improve behaviour and raise maximum attainable gain
Inventor: BLIX RUEDIGER DIPL ING
IPC: H03F1/02
Filed: 1974-09-02
Abstract: The microwave transmitter has the behaviour of its injection-synchronised microwave oscillators (in amplifiers) improved by controlling the phase of the control signal by synchronous frequency modulation of the oscillator. Frequency modulation is accomplished by means of a varactor diode in the oscillator. An IMPATT diode is used as active component for generating the oscillations in the oscillator. The injection synchronised oscillator is modulated by varying the IMPATT diode's current. (The oscillations may be generated by active microwave semiconductor components other than an IMPATT diode). The advantage of this arrangement lies in its increasing the max. attainable gain.
