Patent DE-2752021-A1 (DE)
Inventor: SIEBERS HOLGER
IPC: F23N5/00
Filed: 1977-11-22
Abstract: A regulating device for the size of the air excess in the waste gases of a combustion installation must be intrinsically safe. An output signal (7) of a controller (6) makes a drive (8), which actuates a control element (9) in the air or fuel supply (12), run in the direction of a decreasing air excess. Without output signal (7), the drive (8) assumes a position which corresponds to a predetermined upper limit of the air excess. In the case of too great an output signal (7), that is to say when a maximum achievable travel on the drive (8) in fault-free operation is exceeded, a driver (14) triggers switching contacts (18, 19) via a triggering lever (15) and takes the energy away from the controller (6) or the drive (8). A return button (28) serves for switching on again manually. A thermally actuated lifting element serves as drive (8). The travel of the drive (8) can be superimposed on the travel of a manipulated-variable transmitter for output control of a burner. <IMAGE>

Patent DE-2840474-A1 (DE)
Title: Undercarriage wheel on aircraft - has pockets fixed to its sidewall to rotate it before touchdown and thus reduce wear
Inventor: HEIDEMANN HERBERT
IPC: B64C25/40
Filed: 1978-09-16
Abstract: A number of pockets are vulcanised to the sidewall of a tyre of an aircraft wheel. Their openings face opposite to the normal direction of rotation of the wheel. During the aircraft landing approach, with landing gear lowered, the greater drag applied by the airflow on those pockets on the lower half of the wheel will cause the wheel to be set in rotation in the same direction. Since the wheel is thus already rotating at the moment of touchdown, tyre wear is correspondingly reduced.

Title: Model railway locomotive with centrifugal coupling - which only permits motion after given motor speed is reached to illuminate lights and emit noise
Inventor: HOFMANN DIETRICH
IPC: A63H19/24
Filed: 1978-11-29
Abstract: The model railway locomotive is supplied with current whilst stationary in order to supply lights and to simulate noise emitted by a real stationary locomotive. The two drive wheels (3) are driven by a centrifugal force coupling (6) connected to the motor shaft. The coupling has a cylinder (10) as outer part driving the wheels and pivoted arms attached to an extension of the motor's shaft inside the cylinder. The cylinder remains stationary until the arms (14) of the centrifugal coupling are rotating sufficiently fast to move outwards radially and engage the inside surface of the cylinder in which they are enclosed. The cylinder then starts to rotate and drives the wheels. The lights can therefore be supplied without moving the locomotives.
