Patent DE-2850866-A1 (DE)
Title: Mobile radio locking onto stronger signal - has one HF stage tuned to provide programme output and second HF stage scanning for strongest signal reception
Inventor: PFERDEKAEMPER KARL EUGEN DIPL
IPC: H04B7/26
Filed: 1978-11-24
Abstract: Circuitry locks a mobile radio or t.v. receiver onto the strongest incoming signal, where more than one transmitter is transmitting the same information, by using a tunable h.f. stage inside a particular frequency band. For instance, in a car radio receiving a programme from one transmitter, when the driver is leaving the signal reception area for that transmitter and entering that of another an indicator shows that another transmitter is being received more strongly and he should retune or it is automatically retuned to it for continued good reception. Two h.f. stages receive incoming signals. One stage is used to receive the signal passed through to the audio stages of the receiver. The other h.f. stage steps over the frequencies of other stations transmitting the same signal, controlled by a microcomputer, and compares the signal strength with that from the locked on h.f. stage. Output of the micro-computer is via a d-a converter to the varactor tuned, searching stage, and via a second d-a converter and an automatic or manual tuning selection switch to the locked-on h.f. stage.

Title: Axially locating shaft in bore by spring clip - fitted in annular shaft groove with clip end inclined to permit inserting shaft with clip fitted
Inventor: AUSPRUNG ERICH
IPC: F16B21/16
Filed: 1979-08-24
Abstract: The arrangement axially locates a shaft (1) in the bore of a component by means of a spring clip (4) contained in an annular groove (2) in that shaft. It permits inserting the shaft into the bore with the clip fitted, so that the clip springs outward when the shaft is fully home. In the assembled position, only the end (11) of one spring leg (6) projects outside the groove. This end (11) has an inclined face in a plane parallel to the shaft axis which face engages the edge of the bore on entry of the shaft so that the clip is compressed into the groove. When the shaft is fully home, the end (11) emerges from the groove and so axially locates the shaft.

Title: Internal expanding brake automatic adjustment - has second wedge of min. width equal to max. of first
Inventor: SCHULTZ WERNER
IPC: F16D65/52
Filed: 1980-08-29
Abstract: The automatic mechanical adjustment acts between the two shoes of an internal-expanding vehicle drum brake. A constant-length thrust rod operates at one end with the first shoe, or with the lever hinging on it of a parking brake. Its other end is spring-loaded against a stop rigidly fixed to the second shoe via a self-locking setting wedge. The wedge, stop and thrust rod are freed from each other as soon as the shoes, actuated by hydraulic pressure, move apart for an amount greater than the desired brake clearance. When the rod is lifted free of the wedge, an adjusting spring thrusts it further into the space between the stop and the thrust rod. Between the rod (1) and the second shoe (3) is a further setting wedge (15), bearing against a second stop rigidly fixed to the second shoe (3), and having the same wedge angle as the first one.
