Patent DE-4104937-A1 (DE)
Title: Liq. sensor e.g. for automatic vehicle spray painting system - has choke point in measurement line formed by spring-loaded warning device actuator
Inventor: SCHNEIDER ROLF
IPC: G01V8/16
Filed: 1991-02-18
Abstract: A liquid sensor, which responds to the presence of a liquid in a line, has a housing (1) with a measurement section connecting input and output ports. A warning device connected to the measurement section produces a signal usable for switching when liquid appears in the measurement section. The measurement section contains a choke point (16) with reduced flow cross-section formed by a warning device (18) actuator element (11) movable w.r.t. the inner section wall against spring force. The actuator element is moved by the increase in pressure when the liquid is present but air is passed without triggering a signal. USE/ADVANTAGE - Esp. in electrostatically operating systems. Entire sensor can operate at high voltage.
Patent DE-4107456-A1 (DE)
Inventor: BIEDERBICK MANFRED
IPC: F16L55/10
Filed: 1991-03-08
Abstract: Devices for freezing fluids in pipelines, in order to be able to carry out repairs for example, consist essentially of a sleeve which surrounds the pipe section and through which a fluid or gaseous cooling medium flows. The gaseous cooling medium is obtained by evaporation of a low-boiling-point liquefied gas such as nitrogen. In this case, very low temperatures are used in an uncontrolled manner, which temperatures are undesirable for some pipe materials. In order to be able to carry out the freezing using a gaseous cooling medium at defined higher temperatures as well, the cooling medium in the circuit is passed through the sleeve by the connections (4, 5) for the supply and extraction of the cooling medium being connected to the pressure side (7) and suction side (10) of a fan (8). Provided in the pressure side is a device for the controllable supply of low-boiling-point liquefied gas, for example a spray nozzle (11), which is connected via a control valve (12) to a reservoir (13) for the liquefied gas. Located in the suction side is a pressure relief flap (18) for the removal of gaseous cooling medium. The inlet and outlet temperatures of the cooling medium can be detected on the sleeve by means of temperature sensors (14, 15) and are held constant at a predetermined value by means of a temperature controller (16) which influences the control valve. <IMAGE>

Title: Coefft. equalising method for digital signal receiver compensator - monitoring data signal free amplitude and time interval regions according to coded digital signals
Inventor: HAASS ADOLF
IPC: H04L25/03
Filed: 1991-09-13
Abstract: The method involves operating an equaliser (EZ) in a digital receiver (EE) for compensation of digital signals transmitted over a band limiting transmission line (UELTG).
