Filed: 1978-08-02
Abstract: A light-collecting device in the form of, for example, a rectangularly-shaped body having a so-called "fluorescent plate" with at least one light-exit window is comprised of a solid carrier material having an index of refraction greater than one, such as a polar, water-containing amorphous material based on a polysilicate or a polyphosphate and containing organic or inorganic fluorescent particles therein, which have finite dipole moments with different values in the basic and the excited state, with the fluorescent particles being substantially uniformly distributed throughout the carrier material. In embodiments where the fluorescent particles are organic, an amphiphilic additive, such as a soap, is colloidally dissolved in the carrier material in such a manner that the fluorescent particles are each surrounded by a colloid particle. The disclosed device is useful as a solar collector, an optical indicia transmitter or an image brightener for passive displays.

Abstract: The small PABX with recall facility is for home or office, providing access to an exchange line for up to 10 extensions which all use a common power supply and signalling wire. Each extension has individual connection to the exchange line. Each extension is a four wire unit (SpSt1, SpSt2, SpSt10) with two speech wires (a1, c1, a0, c0, o2, C2) and two control wires (W1, E1, w1, E2, W0, E0). The two control wires are routed directly into the common control (St.E). The speech wires can be connected by relay operation to the exchange line (A1, a, b). The first control wire (E) is for the extension to call, using a press button (ET), the common control (St.E) in order to make an exchange call, if the exchange line is free a relay (A) operates to connect the extension (SpSt1) to the exchange line (A1) via changeover contacs (a11, a12). The control wire (E) is also used for recall so that an incoming call can be diverted to another extension, so that the two extensions can talk a transmission bridge (SB) is provided. A second control wire (W) to extensions enables incoming exchange conditions to be transmitted from the exchange line (AL) via a rectifier bridge (GL), which rectifies ringing currents, and connects battery condition to the common control (on AR), so that extensions may be called.

Title: Balancing rotors with different dia. or balance dia. - corrects for measured dia. and balance unit angle by using rotor dia. sensor and signal processing circuit
Inventor: BIEHL HARALD
IPC: G01M1/34
Filed: 1979-03-02
Abstract: A method and device for balancing rotors of different dia. or balancing dia. involved two or more balancing units (6, 23) slidable radially w.r.t. the rotor (3) axis and each associated with a component of the imbalance. The balancing unit positions are controlled together or individually according to the measured imbalance. Simultaneous balancing of imbalance components is achieved simply and econimically. The magnitudes of the imbalances for each component are corrected for the rotor balance dia. and the angle between the parallel movable balance units (6, 23). The distance between the central axes of the two balance units is selected so that an angle of 90 degrees is achieved between the units for the largest dia. of tested rotor. A rotor dia. sensor (17) provides a processing circuit with a correction input.
