Patent EP-0279329-A2 (EP)
Inventor: WEIHRAUCH GEORG
IPC: A47L23/22
Filed: 1988-02-09
Abstract: The foot mat has a basic body made of plastic or rubber with a multiplicity of deep compartments which are arranged in a honeycomb manner, are open towards the top and at least part of which has a bottom on the underside and the partitions of which form scraping edges at the upper edge, and bristles as further cleaning elements. The foot mat is simplified in terms of manufacture and improved in terms of use by the fact that the bristles made of plastic are welded at their one end, are inserted into the compartments with the still soft plastic end and anchored by this end in the region of the bottom of the compartments after the bristle ends have solidified, the bristle length projecting over the top edge of the partitions being smaller than the length of the bristles situated in the compartment. <IMAGE>

Abstract: Der faseroptische Stellwertgeber weist eine Lichtleitfaserspule (1.2) mit midestens einer Wicklungslage auf, innerhalb der zwischen benachbarten Windungen die Abschnitte der Lichtleitfaser gleichlang sind. Einen Druckfinger (2.2), der mit einem mechanischen Wegaufnehmer (2) verbunden ist, wird über die Wicklungslage geführt und übt dabei auf eine vergleichsweise schmale Stelle der Lichtleitfaser einer Windung einen mechanischen Druck aus, wodurch in der Lichtleitfaser ein sogen. microbending-Effekt erzeugt wird. Eine optoelektronische Sende- und Empfangseinrichtung, welche mit der Lichtleitfaser verbunden ist, ermittelt den Ort, der durch den Druckfinger (2.2) verursachten Druckstelle und damit die Position des Druckfingers (2.2).

Abstract: 2.1. Hitherto, the edges of extruded sections have been rounded off by machining. This is expensive since the tool has to be reset. With the new tool, the edges are to be rounded off and compacted in such a way that a tolerance zone of +/- 0.3%, relative to the length and width of the workpiece, can be processed. The thickness tolerance is to be no more than +4%. The fatigue strength of the cut section is to be increased. 2.2. Between the flanks (1, 2) and (3, 4) respectively of the upper die (5) and lower die (6) respectively and of the upper die face (7) and of the lower die face (8) respectively, an angle of inclination alpha = 96-105 DEG  is provided and, in the corners (9, 10) and (11, 12) of the upper die face and of the lower die face, respectively, a radius of 1-5 mm is provided. The clear width between upper die face and lower die face in the closed condition is 10-50 mm. The thickness of the extruded section has an oversize of 1-3% and the section is placed between the two die halves, which are driven together abruptly, leaving no gap. 2.3. Rounding off and compaction of the edges of extruded sections composed of aluminium, in particular AlMgSi. <IMAGE>

Abstract: The higher the voltage applied to an electrical device comprising a PTC conductive polymer, the more likely it is that intermittent application of the voltage will cause the device to fail. According to the invention, the likelihood of such failure is substantially reduced by irradiatng the PTC conductive polymer (1) so that it is very highly cross-linked, for example to a dosage of at least 50 Mrads, preferably at least 80 Mrads, especially at least 120 Mrads. In this way, for example, it is possible to make a circuit protection devce which will continue to provide effective protection even after repeated exposure to a voltage of 200 volts.

Abstract: A wide band amplifier for operation at very high frequencies, for example in the 20MHz to 50GHz range comprises a MESFET distributed amplifier (22) having a gate and a drain transmission line, a first hybrid circuit (18) to apply a first and second input signal to opposite ends of the gate transmission line, and a second hybrid circuit (26) connected to opposite ends of the drain transmission line to receive and combine first and second output signals from the drain transmission line to provide an amplified output signal. The use of two input signals travelling in opposite directions along the gate transmission line increases the gain which can be achieved in the distributed amplifer and reduces the noise component of the output signal. It is particularly useful for enhancing the performance of a distributed amplifier containing only a few MESFETS.

Abstract: An echo canceller (1) for full duplex digital data transmission in a transmitter/receiver unit when connected via a hybrid circuit (2) to one end of a two wire line (3). In order to provide adequate cancellation at a line data rate of 160 kbit/s over 7-8 km, a data bit history of at least 9 bits is used to address a memory having at least 3 partitions (41-44) with the first partition (41) being addressed by a sequence of at least 3 data bits. This partitioning achieves a small memory size, less than 2 kbits, and a small total chip area for integrated circuit realisation of the canceller together with a clocking speed for moderate power consumption is maintained by using serial arithmetic (61-63) for adding the partition outputs together with pipelining (D1, D21 - D24). An exponentially quantitising analogue-to-digital converter error signal circuit (9), shown in detail in Figure 2, is used which has wider application to echo cancellers other than the partitioned memory compensation type.

Abstract: A power cycle to operate with maximum temperature above 300°C, working with a mixture of water and another substance having lower volatility, greater molecular weight and tendency to superheat in the isentropic expan­sion. Both substances are vaporized in a boiler, in part at variable tem­perature, and expanded in at least one turbomachine (T-I). After the first expansion, a heat yielding takes place at constant pressure (RS), wherein part of the least volatile substance condenses at variable temperature. In comparison with the steam cycle, this new cycle offers higher efficiencies because it has, among others, the advantage of increasing the average temperature of heat absorption, without intermediate reheating and without condensation occurring in the turbine until very low exhaust pressures are reached, depending on the proportion of the mixture used. It also facilitates, in the case of combining with a secondary cycle of refrigerant fluid, the superheating of this fluid, which is especially useful in the case of fluids with wet expansion.

Abstract: The device (1) is one possible embodiment of the device according to the invention. Its underside (12) is closed off by a lower contact- adhesive layer (2) which covers the underside (32) of the fabric base layer (3) and, owing to the uneven surface structure of the latter, adheres relatively weakly. Affixed to the upper side (31) of the fabric base layer (3) by means of an intermediate contact-adhesive layer (34) which is even on top and therefore adheres better is a foam layer (4). This foam layer (4) compensates, in use, for relatively small unevennesses in such a way that the electrically conductive filaments (6) carried on its upper side (41) by an upper contact- adhesive layer (5) on the upper side (51) of the latter are constantly in electrically conductive contact with the floor covering. With a device (1) of this type it is thus possible to lay antistatic or conductive floor coverings on any desired floor, without the need for expensive prior working of the latter, in such a way that on the one hand long-term static charges can be safely conducted to earth by it and, on the other hand, if desired, the floor covering can again be held by the floor without damaging the foundation and while retaining its possible reusability. <IMAGE>
