Patent DE-3008936-A1 (DE)
Inventor: PAPST GEORG
IPC: G11B15/10
Filed: 1980-03-08
Abstract: The actuation of the tape and magnetic-head guides in audio tape apparatuses has been carried out in the past by using short levers, since long levers could cause inadmissible deformations, in particular in the case of cassette audio tape apparatuses, which have lightweight chassis. For multi-shaft drives, stable chassis are used, which permit longer actuating levers and consequently easier operation. In the case of the present mechanism, an actuating lever (31), which actuates the magnetic head (311) and the pinch roller (62), is arranged in a movably mounted manner at a considerable distance from the magnetic head (311), thereby achieving easier and operationally more reliable actuation. <IMAGE>

Title: Transmission system for control signals within aircraft - uses optical fibres carrying digital commands and processors to raise safety
Inventor: WENDT HANS JOACHIM
IPC: H04B10/278
Filed: 1980-09-02
Abstract: The system consists of a network of optical fibres carrying digital optical signals forming control commands for the aircraft's elevators etc. The control commands are produced by control elements (9) and pass via signal processors (10) to the network, which carries them to servo units (14). The processors are coupled to mixers and to a data system. The servo units are addressable. The power supply system comprises several separate power sources each of which can be switched in independently. The power sources may be a jet engine (8), an auxiliary turbine, a wind-driven turbine or a battery. Each power source has its own switch and own monitor each of which is connected via three (redundancy) parallel transmission units to the control network. The control network connects them to a test unit that controls and monitors the units. The advantage of using optical fibres lies in avoiding the effects of delays, reflections and stray electromagnetic fields experienced in conventional electric cable or wire networks. The system also performs preprogrammed safety operations if a component or unit fails. Safety in general is increased. To this end the supply transmission units are provided in triplicate to raise the level of safety of the supply system to that of the control system.

Title: Micronutrient fertiliser
Inventor: HAUSCHILD HELMUT
IPC: C05D9/02
Filed: 1981-02-14
Abstract: The invention relates to a micronutrient fertiliser composed of ion-exchanger resin which is loaded with anions and cations and used for filling fertiliser containers which are designed to take a flow of liquid. To recognise clearly that the ion-exchange capacity of the ion-exchanger resins is exhausted, the invention provides that the fertiliser container is transparent and that an indicator resin which is loaded with coloured ions is admixed to the ion-exchanger resin which is loaded with anions and cations, namely in such an amount that the first colour of the indicator resin changes into a second colour when the exchange capacity of the ion-exchanger resin is exhausted, both these colours being different from the colour of the loaded and the exhausted ion-exchanger resin.
