    Abstract: A melt spinning apparatus for spinning a synthetic yarn, wherein the yarn is formed by combining a plurality of filaments and wound to a package by means of a takeup device downstream of the spinning apparatus. Downstream of the spinneret, an inlet cylinder with a gas-permeable wall and a cooling tube are arranged. The cooling tube connects to a suction device such that an air stream forms in the cooling tube in the direction of the advancing yarn. This air stream assists the advance of the filaments and leads to a delayed cooling. To ensure adequate cooling of the filaments within the cooling zone, an air supply device is provided for generating an additional cooling air stream which flows in the axial direction of the cooling tube for cooling the filaments downstream of the inlet to the cooling tube.

    Abstract: A ventilation arrangement for the head space of the fuel tank of a vehicle comprises a switchable main valve intended for adjusting an arbitrary pressure in the head space of the tank. By way of the opening position of the main valve, a connection between a connection (5) intended for connection to the head space and a connection (6) intended for connection to the surrounding atmosphere is established, wherein the main valve is assigned a pilot valve, which opens during a first path element of a switching movement, wherein the main valve only opens following this first path element. Because of the small cross section of the pilot valve and the pressure relief that materialized through its opening, the switching power can be reduced and a smaller size drive can be employed.

    Abstract: The invention relates to a gas detection system (1) for detecting gases, vapors and biological pathogens, having at least one receptor (4) arranged on a line (5) connecting the ambient air (7) to an air storage unit, wherein the gas detection system (1) is designed as a “breathing” system containing clean CO2-carrying and moisture-saturated air in the air storage unit (2), wherein the operating temperature of the gas detection system (1) is the room temperature. Additionally, a method is proposed for detecting gases, vapors and biological pathogens using the inventive gas detection system. This avoids the shortcomings of the known solutions of the prior art, and an improved and more cost-effective solution for detecting trace gases is made available.
