Device for applying a treatment substance (), in particular starch, on at least one side of a running product web (), in particular a paper or board web, by means of a least one curtain coater () having a discharge nozzle () and at least one press nip (N) following the curtain coater () for forming a hydraulic pressure when the product web () passes through a press nip (N) which is formed by one of two rotating press rolls and which causes the treatment substance () to penetrate into the product web (), wherein the at least one press nip (N) is equipped with at least one heated applicator roll () as a press roll to increase the penetration of the treatment substance () into the product web (), and at least one of the two press rolls () is designed with a fixed or adjustable crown () for the adjustment of a line load in a range of 20 to 200 kN/m.

Device for applying a treatment substance

Method for producing wet-laid non-woven fabrics, with which an aqueous suspension comprising fibres is laid down on a screen and is dewatered using suction boxes under the screen to form a sheet of non-woven web which is removed from the screen and guided to at least one subsequent treatment unit before the non-woven web can be wound, and transferring of the non-woven web from the screen to the at least one subsequent treatment unit and/or transferring of the non-woven web to interfaces between treatment units on the start of production and/or after an interruption in production, using a web feed, wherein web is fed via a temporarily closed draw of a free draw between the screen and the at least one subsequent treatment unit and/or of a free draw at an interface between treatment units, and the respective temporarily closed draw is produced via air flows, which lift off an end feeding strip as part of the running non-woven web by blowing, adhere same to a transport path device by generating negative pressure and lift up same at the following treatment unit by suction.

A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.

Vacuum belt conveying device for guiding a moving web, in particular a web threading strip of a paper or board web, having an air-permeable transport belt guided endlessly in a loop with an upper run and a lower run, and a device arranged within the loop for applying a vacuum to the inner side of one of the runs of the transport belt in order to hold the web firmly on the transport belt, in which the device for applying a vacuum is formed by means of at least one long-gap ejector, which in each case has an air jet injector having a large number of air outlet nozzles along the inlet side of the long gap and, on the inlet side, is positioned at a distance under the inner side of the run which is provided to hold the web firmly.

A sensor for determining a physical property such as the concentration of a gas component or the temperature of a measuring gas, e.g., the exhaust gas of internal combustion engines, has a sensor element which is secured in a housing and is surrounded at an end section on the measuring gas side by a protective tube and surrounded at an end section on the connection side by a protective sleeve, and also has a radially projecting flange for securing the sensor on a sealing seat formed on a measuring gas duct. To reduce manufacturing costs, the flange is molded onto the protective tube as one piece. The protective tube is manufactured as a deep-drawn part, and a trimming edge remaining after deep drawing on the end side is used as a securing flange.

Sensor

A measurement sensor for determining a physical property of a measurement gas, e.g., the concentration of a gas component or the temperature of a measurement gas, in particular of the exhaust gas of internal combustion engines, has a housing and a sensor element accommodated in the housing. The sensor element has an end segment at the measurement gas side that protrudes from the housing and a connection-side end segment that bears at least one contact surface. The sensor element also has at least one conductor element that contacts the at least one contact surface. In order to achieve low transition resistances at the electrical contacting and a decoupling from mechanical stress, the contact surface and the conductor element are connected to one another by welding, and are embedded in a ceramic compound at least in the area of the welded connection.

Electrical connecting lines of a sensor element are anchored by friction locking, specifically using an annularly closed spring element which clamps the connecting lines against contact surfaces on the sensor element using pressure bodies.
