Patent DE-2736119-A1 (DE)
Inventor: PETRY SIGMAR
IPC: H04Q3/54
Filed: 1977-08-10
Abstract: In a telephone switching system with a multiplicity of connection-individual switching devices (H1, H2, ..., Hn), two central processors (Z1, Z2) coordinated with one another are provided jointly for these. One of the two processors (Z1, Z2) is always in operation and the other one in reserve. They are changed as a matter of routine and/or during operational faults. Change-over devices (U1, U2) individually allocated to the central processors (Z1, Z2) are connected with a bus-enable output (e1, e2) not only to the input/output gate circuits (Gil1...Gin1, Gbl1...Gbn1, Gil2...Gin2, Gbl2...Gbn2) of the connection-individual switching devices (H1, H2,..., Hn), used for connection to a common databus (L1, L2), but also to the inhibit input (S1, S2) of the change-over device of the respective other central processor (Z1, Z2). A failure of the bus-enable signal of one change-over device (e.g. U1) causes the central processor (e.g. Z2) corresponding to the other change-over device (e.g. U2) to take over operation of the connection-individual switching devices (H1, H2,...,Hn). <IMAGE>

Title: Contactless switch using ferromagnetic core moving inside coil - whose induced output signal depends on position of wire in coil
Inventor: HAUSSERMANN GERHARD
IPC: H03K17/97
Filed: 1979-02-12
Abstract: The switch consists of a ferromagnetic core moving axially inside a coil. The core is moved by an external device and the resulting voltage induced in the coil is used as switching voltage. The coil may be a differential transformer whose output signal's phase and/or amplitude depend on the position of the core inside the coil. The coil may be supplied with mains frequency or from its own oscillator. The output signal from the coil is passed to a demodulator that produces a d.c. signal dependent in magnitude on the amplitude and in sigh on the phase of the coil's output. A discriminator is coupled to the demodulator's output. This arrangement provides a contactless switch of long useful life.

Title: Prestressing of blades of circular saws and bandsaws - by applying force to heated blades at temp. to reduce yield stress
Inventor: ETTELT BERNHARD PROF DIPL ING
IPC: B23D63/18
Filed: 1979-05-10
Abstract: Bandsaws and circular saw blades are pre-stressed to improve their functioning. This pre-stressing is usually carried out by hammering or rolling, but this often results in an uneven stress distribution. the invention proposes to pre-stress saw blades by heating them up to red heat to reduce the yield stress and applying an external force which is maintained during cooling. When the force is removed there is a tensile stress in the heated zone and a compressive stress in the remaining areas. With circular saw blades the force is applied by rotating the heated blade at high speed to generate centrifugal force.
