Patent EP-0439731-A1 (EP)
Inventor: HOPF KARL-HEINZ
IPC: B01D5/00
Filed: 1990-12-06
Abstract: A phase-separating device and a corresponding process are described for the thermal separation of an emulsion, especially a water/oil emulsion. The device comprises a vessel for receiving the emulsion, heating apparatus for heating the emulsion located in the vessel, a flue for withdrawing volatile constituents of the emulsion and also a condenser, attached to the flue, for condensation of the constituents in the vapour state. In known devices, the differences in boiling point of the individual liquids are utilised, vapour of the liquid with a lower boiling point being removed from the surface of the emulsion by suction and being separated in a condenser. However, devices of this type are disadvantageous, in that they give rise to a very high energy consumption. To achieve the desired aim of producing a phase-separating device of the generic type, which, with improved efficiency, has a comparatively lower energy consumption, the phase- separating device according to the invention is characterised in that an apparatus is provided for divided introduction of air into the emulsion, whereby, because the introduction of air into the heated emulsion is divided over the surface, vapour formation occurs at substantially lower temperatures than the actual boiling temperature of the liquid. Separation of the liquid with lower boiling point can thus be achieved at considerably lower temperatures.

Abstract: The invention relates to a connecting device for hydraulic lines and the like. A housing (1) is present, in which a collet (6) is arranged. The latter has an axially displaceable operating sleeve (8) on which a plurality of clamping elements (9) are arranged. Bending points (14), which permit pivoting of the clamping elements (9), are provided between the clamping elements (9) and the operating sleeve (8). Each clamping element has a radially projecting pressure section (16) which is axially, internally opposite a supporting surface (21) which is fixed to the housing. If it is intended to release a hydraulic line (5) which is clamped in the collet (6), pressure is exerted on the operating section from the exterior, as a result of which pivoting of the clamping elements (9) into a release position takes place, because of the support on the supporting surface (21). <IMAGE>

Abstract: A Doppler blood flow system and method in which an ultrasonic wave (16) is reflected off of red blood cells (24) in blood flowing in tubing (20). The reflected ultrasonic wave (26) is digitally processed in the frequency domain. The flow rate of the blood is directly related to the average frequency of the Doppler signal. Because the Doppler blood flow system calculates flow rate solely on the basis of frequency, a special case exists at zero rate of flow where the received signal is not a valid Doppler flow signal, but rather purely noise. The noise at zero flow rate is random and will not have an average frequency which is unique to zero flow. The Doppler blood flow system and method must invoke a special case determination of when a zero flow condition in order to accurately provide a blood flow rate. The system utilizes a method of determining the rate of flow of a fluid containing particles flowing through a tube. An ultrasonic signal is transmitted through the tube at an oblique angle thereto. The ultrasonic signal which has been reflected off of the particles contained in the fluid is received as a received ultrasonic signal. The rate of flow of the fluid is calculated from the received ultrasonic signal using Doppler techniques. Whether the special case of the value of the rate of flow being equal to zero exists is determined and the value of the rate of flow is set equal to zero for the special case.

Date Jun. 13, 1991.A passive optical network includes a head-end station and a plurality of terminations. The terminations are responsive to control signals from the head-end station. The head-end station is arranged to receive frames having a predetermined bit rate and comprising signals transmitted by the terminations. Ranging pulses are transmitted from each of the terminations to the head-end station where the received ranging pulses are sampled at a high sampling rate greater than the predetermined bit rate. The data samples are applied to a processor which determines the phase and amplitude of the ranging pulses and generates control signals for the terminations to modify the phase or timing and amplitude of the transmissions from the terminations. A locally generated marker pulse may be applied to the incoming data frame before it is sampled in the head-end station, the marker pulse providing a phase and amplitude reference for use by the control processor.

Abstract: An earth-leakage current circuit breaker having a summing current transformer in whose secondary circuit a trip device (2) is arranged which makes an engaging connection with a latching mechanism which acts on switching contacts in leads which are to be monitored, the trip device (2) being bridged by a first voltage-dependent resistor (3) in order to prevent erroneous tripping, as a result of overvoltages, caused by surge currents resulting from overvoltages, the resistance of which first resistor (3) has such a characteristic that, above a threshold, its resistance drops with increasing voltage, that one or more capacitors are arranged, especially in the tripping circuit, which capacitors are tuned to the power matching or pulse-current sensitivity, an additional, further voltage-dependent resistor (7) being connected in parallel with the trip device (2), the response voltage of which further resistor (7) is selected such that it is above that of the first voltage-dependent resistor (3). The "cold redundancy" which is thus implemented results in particularly reliable protection of all the components of the trip circuit against damage resulting from overvoltages. <IMAGE>
