Abstract: Arranged on the roof (4<1>) of the driver's cab (4) is a headwind deflector (1) by means of which the headwind is passed over the box-shaped body (5) in an aerodynamically favourable manner, at the same time greatly reducing the air resistance. This has the result that the air resistance caused by the body (5) does not impair the travelling speed, and the need for power is reduced. This headwind deflector is constructed in the form of an aerofoil which has a respective transverse metal tube (2, 3) at the front and rear ends. The headwind deflector is swivellably secured by the front metal tube (2) on the roof (4<1>) of the driver's cab, and longitudinally adjustable support feet (6<1>, 6<2>) are fixed to the rear metal tube (3) by one end and are secured by their other end on the roof (4<1>) of the driver's cab. The said support feet hold the headwind deflector in a position counter to the travelling direction obliquely upwards and to the rear such that it can be adjusted. <IMAGE>

Patent DE-2728378-A1 (DE)
Inventor: KERLER MANFRED ING GRAD
IPC: G05D16/20
Filed: 1977-06-24
Abstract: Filter elements in a filter press are closed and made tight by the automatic adaptation and control of their closing force in correspondence to their opening force. The opening force, of variable magnitude, is generated by the pressure of the fluids introduced into the cavities of the filter elements. Signals corresponding to the pressures of all fluids (e.g., suspensions, washing fluids, air under pressure) introduced into the cavities of the filter elements, continuously measured by manometers (1, 2, 3, 4), are compared with a signal corresponding to the closing force to produce a reference signal, available at any time, which permits adjustment of the closing force. The reference signal is used by controlling apparatus which carries out the adaptation and adjustment of the closing force.

Title: Negative feedback system for loudspeaker - derives feedback from light beam modulated by movement of diaphragm and picked up by photodiode
Inventor: MUELLER-BOEHM DIRK
IPC: H04R3/00
Filed: 1978-04-10
Abstract: A stabilised d.c. supply feeds a light source, from which a focussed light beam passes to a photodiode. The light beam is tangential to the diaphragm of a loudspeaker so that movement of the diaphragm modulates the light and therefore the electrical output of the photodiode. After amplification and inversion this signal is added to the audio input signal to provide negative feedback. The resultant signal is impedance matched and fed into the output amplifier. The sampling method does not interfere with the functioning of the loudspeaker and is relatively simple.
