Patent DE-3942339-A1 (DE)
Inventor: KALMER MATHIAS DIPL ING
IPC: H04H20/00
Filed: 1989-12-21
Abstract: The RDS broadcast receiver described starts an automatic station-finding run for a new program chain if no further alternative frequencies of the program previously received are available to it which are suitable for reception when there is a deterioration in the conditions of reception. To avoid the receiving set adjusting itself to a program chain of the neighbouring country in mobile use in the area of the border to a foreign-language neighbouring country because its quality of reception is found to be particularly good, a device is provided with which the receiver preferably only searches for transmitters suitable for reception, the country code of which corresponds to that of the transmitter previously received. Transmitters with deviating country code are also accepted only after the entire receiving range has been searched without success. <IMAGE>

Abstract: The axle-brake disc provided, in particular, for high-speed goods waggons, has a one-piece braking ring (6), which has two friction-ring portions (8) offset axially relative to one another and ventilation portions (9) connecting the latter. The ventilation portions (9) and the friction-ring portions (8) delimit cooling-air channels (10) through which cooling air can flow radially from the inside to the outside. The axial width of the braking ring (6), measured between the respective axially outer faces (7) of the friction-ring portions (8), is between 150 and 200 mm, preferably 170 mm, and the ratio of the axial to the radial width of the braking ring is from about 1.0 to 1.4. This dimensioning makes possible optimum heat dissipation from the friction-ring portions (8), through the ventilation portions (9), to the cooling air flowing through the cooling-air channels (10).
