Title: Digital RF modem
Inventor: FUHRMANN HANS DIPL ING
IPC: H04L27/10
Filed: 1983-09-14
Abstract: For a device used to transmit and receive binary-coded data which are transmitted by means of a frequency-modulated RF carrier, from or in a station which has a modulator and a demodulator, a uniform cost-effective component is intended to be specified for the transmitter and receiver for each data station. To achieve this, both the RF carrier for the modulator and the width of the evaluation windows for the demodulator are derived from a pulse sequence generated by a crystal-stabilised oscillator through programmed division (matrix 1, counter 2 and matrix 5, counter 6), a specific RF channel and, for this channel, either the channel mid-frequency or, by means of a serial input signal, the modulated carrier in the form: mid-frequency + deviation or mid-frequency - deviation being set via the programming inputs of the modulator, a receive channel being defined via the programming inputs of the demodulator, and the demodulated RF signal emitted from the serial output is checked to determine whether it lies within the evaluation window: mid-frequency + deviation +/- tolerance or within the evaluation window: mid-frequency - deviation +/- tolerance. <IMAGE>

Title: Method and device for the lubrication of bearings of a rotary machine
Inventor: ZIMMERN BERNARD
IPC: F04C29/00
Filed: 1985-02-08
Abstract: A refrigerating machine contains a compressor (1) and, in a closed circuit between the outlet and the inlet of the compressor, a condenser (24), a storage tank (25), an expansion valve (26) and an evaporator (27). The fluid in the circuit contains a small amount of dissolved oil. The liquid from the storage tank (24) is fed to a heated oil storage tank (132), which has outlets (151, 152, 153), which are connected to bearings of the compressor. In this oil storage tank the liquid is evaporated whilst oil is deposited. The gas resulting from this distillation process escapes through the outlets (151, 152, 153) to the bearings. Separate means (136 to 138, 140 to 145, 154 to 156) are provided for charging the gas escaping to the bearings with oil droplets. For this purpose each outlet duct leads under the oil level (146, 147) and is connected by way of a micro-aperture (154 to 156) to the oil. This method results in reliable lubrication of the bearings under relatively constant conditions.
