A textile material having a surface structure is disclosed which includes at lea st two different needled base fleeces, whereby the base fleeces have a surface structur e obtained by needling from at least one side, whereby the needles used for the structure needling are forked or crowned needles, the depth of the forks or the burs thereof being selected so that they completely fill with fibers of...

An operating device for a Venetian blind includes a rotary tilt control unit which is adapted to be coupled to a shaft of the Venetian blind so as adjust tilting angles of slats. A positioning tube is connected to the tilt control unit and has a top opening and an axially extending slot. A retaining member is axially movable in the positioning tube, and has a tapered upper end portion extendible t...

An adjustable variable flow restriction element and an extruder containing the same are provided for mechanically controlling the bulk density of an extruded m aterial. The adjustable flow restriction element is located in an extruder proximate to t he die of the extruder in position to partially block the downstream flow of material thro ugh the extruder. The adjustable flow restriction element i...

A speech communication system comprises a receiving unit 14 which receives speech data and uses that data to output speech 15. The characteristics of the speech received by the decoding unit are altered by a processing unit 10 based upon an analysis of the listener's current background noise before the speech is output to enhance its intelligibility to a listener. An analysis unit 12 determines th...

The present invention relates to a catalyst system based on monoazadiene metal complexes of the formula (see fig. I), and a co-catalyst suitable for activating the metal complex, and to the use of t he catalyst system for the polymerization of unsaturated compounds, especially for the polymerization and copolymerization of olefins and/or dienes. The novel catalyst system is characterised in partic...

The object of the invention is a thermometer based on CB tunnelling, which comprises a sensor component and devices for measuring its voltage-current dependence. The sensor includes a chain of several, at least ten, nanoscale tunnel junctions (10, 10") and connection electrodes (2, 3, 3', 3") for connecting the measurement devices to the ends of the chain. The temperature is determined in a manner...

A system for controlling the atmosphere in the container comprises a membrane separation apparatus and a second separation apparatus, adapted to separate nitrogen and to separate carbon dioxide and water vapour respectively from a gas mixture in the container comprising nitrogen, oxygen, carbon dioxide, water vapo ur and ethylene. The separated nitrogen is returned to the container, as is at leas ...

Briquettes useful as fuel are produced from dehydrated sewage sludge containing 65 weight percent or more sewage sludge solids. The briquettes on a dry basis contain from about 50 to about 95 weight percent sewage sludge solids together with from about 3 to about 12 weight percent lime as binder and fungistat. Organic binders and coking agents may be included in the briquettes to improve resistanc...

While, in a prior art combined cycle power generation plant, steam which is needed at the time of restart of the plant after the plant has been once stopped must be supplied from outside auxiliary boiler which requires additional facilities resulting in complexity of plant, high cost, troublesome operation, etc., the present invention provides such a plant that is able to secure the steam needed a...

The position of the phone is calculated taking into account the speed of which it is travelling through the cell, by calculating the speed according to the difference in positional data supplied to a sequence filter by two or more sensors. At least one of the sensors is used to provide data for the speed with which the phone is moving through the cell, and the actual data used to record the posit...

A packet switching apparatus is disclosed which is adapted to determine and control an allowed transmission rate of a transmitting terminal in a packet switching network. The packet switching apparatus comprises a rate discriminator to monitor an interval of packet reception for each of connections, judge, based on the interval of packet reception, whether the transmitting terminal having sent the...
