Title: Electrical humidity tester - has glass fibre reinforced printed probe and LED circuit requiring minimal power
Inventor: GRIEBEL ROBERT
IPC: G01N27/04
Filed: 1978-09-21
Abstract: The measuring probe of a one way humidity tester is produced similarly to a printed circuit, and the use of an LED together with a bC 307 transistor, makes an operating switch unnecessary, since the flow of current at rest is negligible. The probe may be enclosed in a glass fibre reinforced epoxy resin and the housing is an epoxy resin moulding. Unlike conventional humidity testers, this works effectively and requires no attention. In the household it can be used not only for checking plants and flowers but also or detecting various sources of damp.

Patent DE-2853422-A1 (DE)
Inventor: MUTRUX CLAUDE
IPC: H02J7/02
Filed: 1978-12-11
Abstract: The invention relates to an electronic timepiece provided with an electroacoustic transducer for transmitting acoustic signals to indicate a time of alarm, and also for receiving information in the form of acoustic signals to control different functions of the timepiece. Coded acoustic information is delivered to the transducer, for example, by a special apparatus intended for that purpose, and serve to control different functions of the timepiece through a watch and transducer control logic network. The logic network is interconnected with the frequency divider chain, a display control circuit, and a transducer. The logic network includes a selector which connects the transducer either to the output of an alarm logic circuit for delivering alarm signals to the transducer at the time of alarm, or to a transducer detector for transmitting the electrical signals delivered by the transducer acting as a microphone to a watch logic circuit. The watch logic circuit, in turn, controls the alarm logic circuit, the frequency divider chain, and the display control circuit of the timepiece.

Title: Automatic steering of non-tracked vehicle with routing cable - uses horizontal and vertical coils on vehicle to record signals from cable
Inventor: AUKSUTAT GUENTER DIPL ING
IPC: G05D1/02
Filed: 1979-01-27
Abstract: An automatic steering system for non-tracked vehicles uses a conducting cable along the route to be covered supplied with a.c. The magnetic field is measured in a horizontal coil on the base of the vehicle and in a vertical coil fitted to the vehicle. An electrical signal is obtained in this manner, which is a function of the distance of the coil system from the conducting cable. This is achieved without affecting the vertical distance between the coil system and the conducting cable. The voltage induced in the vertical coil is rectified. It is then fed through a multiplication circuit to form a product, which is induced into the horizontal coil. The rectified voltage in the horizontal coil is fed through a divider circuit and is used to control the steering.

Title: Protection against noise in radio control receivers - using digital controller with signal pulse sequence to eliminate spurious switching states
Inventor: STEINLEIN HANS-WOLFGANG
IPC: H02J13/00
Filed: 1979-04-17
Abstract: A digital radio control unit is structured to avoid false command generation conductors due to noise by requiring a strict pulse sequence. For a double command system, or one in which an actuator is switched on by one pulse, and is switched off by another, a start impulse signals the initiation of a command sequence, and the on command or off command also occurs withinn a fixed interval. Any noise generateed signal being outside the window is inhibited. The system uses a decoder to generate an input to a memory for the transmission sequence data storage and a logic unit controls the signal generator.
