Patent EP-0539355-B1 (EP)
Inventor: GRINBERG JAN
IPC: G01J5/20

Granted: 1995-01-11
Abstract: An infrared (IR) simulator is disclosed in which an array of pixels is defined on an insulative substrate by resistor bridges which contact the substrate at spaced locations and are separated from the substrate, and thereby thermally insulated therefrom, between the contact locations. Semiconductor drive circuits on the substrate enable desired current flows through the resistor bridges in response to input control signals, thereby establishing the appropriate IR radiation from each of the pixels. The drive circuits and also at least some of the electrical lead lines are preferably located under the resistor bridges. A thermal reflector below each bridge shields the drive circuit and reflects radiation to enhance the IR output. The drive circuits employ sample and hold circuits which produce a substantially flicker-free operation, with the resistor bridges being impedance matched with their respective drive circuits. The resistor bridges may be formed by coating insulative base bridges with a resistive layer having the desired properties, and overcoating the resistive layers with a thermally emissive material. The array is preferably formed on a silicon-on-sapphire (SOS) wafer.

Abstract: A device is disclosed for automatic taking-out of articles, in particular of containers from a roller conveyor. The device contains a pivotable rocker which, at its discharge end, carries a stop device for the containers situated on the roller conveyor. Arranged at the other end of the rocker is an overrun device which, in the unpivoted state of the rocker, lies under the conveying plane of the roller conveyor. As a result of the pivoting of the rocker, the stop device is lowered and the front container can be removed from the roller conveyor, while the subsequent container can be prevented from further movement by the overrun device. After the removal of the container, the rocker pivots back into the initial position and the subsequent container is conveyed on to the stop device at the end of the roller conveyor. <IMAGE>

Abstract: In the device for taking milk samples from a milk feedline (1), in order to remove any milk residues left adhering in a suction line (5) and an injection needle (6) by the previous supplier, before the current supplier takes samples, the suction line (5) and injection needle (6) are filled with milk and, after being filled completely, are emptied again by pumping the milk back into the feedline (1). The complete filling is monitored by a control means (9) which controls a hose pump (7) in such a way that only the milk quantity just necessary for filling the suction line (5) and injection needle (6) is conveyed. Not until after this filling and emptying operation is the injection needle (6) introduced into a sampling bottle (8) arranged on a liftable plate (15). A holding-down device (16, 17, 18) guarantees that the injection needle (6) is stripped off perfectly from the sampling bottle (8) during the lowering of the plate (15) at the end of the sampling operation. The apparatus is characterised by the simple method by which residual milk can be removed from the suction line and injection needle in order to prevent carry-overs.

Abstract: Die Erfindung betrifft eine Überwachungseinrichtung für eine Zündungsendstufe an einer Brennkraftmaschine mit einer Schließzeitbegrenzungseinrichtung, für die über eine Versorgungsspannung (UBATT) versorgte Zündungsendstufe (5). Die Schließzeitbegrenzungseinrichtung wird über ein Steuersignal bei Feststellung des Schließzeitpunkts in Lauf gesetzt und steuert die Zündungsendstufe für eine Zündung in dem Fall an, daß bis zum Ablauf der Begrenzungszeit keine Zündung erfolgt ist. Erfindungsgemäß wird die Dauer der Begrenzungszeit (t = f (UBATT)) als Funktion der Versorgungsspannung (UBATT) variabel einstellbar ausgeführt, dergestalt, daß bei höherer Versorgungsspannung (UBATT) die Dauer der Begrenzungszeit reduziert wird. Dies führt dazu, daß eine thermische Schädigung oder Zerstörung einer Zündungsendstufe durch zu lange Schließzeiten verhindert wird und keine Überdimensionierung einer Zündungsendstufe erforderlich ist.

Abstract: A distributed temperature sensor comprises an elongate ultrasonic waveguide having a number of zones along its length, each zone having a grating formed in it. This is typically achieved by incorporating uniformly spaced notches or bands (or collars) throughout the zone. The grating spacing in each zone is different, so that each grating reflects a characteristic frequency. This frequency varies as the temperature of the zone varies, so if wide-band ultrasonic pulses are launched into the waveguide, the temperature of each zone can be determined from the reflected frequencies.
