The radiation chamber essentially comprises a rectangular cross-section and is bordered by two side walls as well as a base wall and a ceiling wall. The side walls and the base wall comprise a non-metallic material. Additionally, a number of lamp units are provided. The lamp units each have a radiation source and a cover tube surrounding the radiation source, and, the lamp units are essentially cylindrical in shape. The lamp units lamp units in at least one cross-direction are arranged towards the flow direction.

Abstract: In a diesel pile hammer, the circumferential surfaces of a piston and striker extend axially to such an extent that, when the piston and striker bear on one another, they are separated only by a very small distance. In their near-edge sections, the piston end face and striker end face are each provided with an annular trough having a semicircular cross section. In this way, when the piston has traveled fully against the striker, a basic working space is obtained, having the form of an annular space with a circular cross-section, in which combustion commences.

Abstract: A projection exposure device (1), in particular for micro-lithography, serves to produce an image of an object (2) in an image plane (11) positioned in an object plane (10). For this reason the projection exposure device (1) has a radiation source (4) emitting projection radiation (5). Illumination optics (6) are positioned between the radiation source (4) and the object plane (10) and projection optics (8) are positioned between the object plane (10) and the image plane (11). A detection device (30) is provided to measure the illumination angle distribution of the projection radiation (5) in a field plane (10). This communicates via at least one control device (34, 18) with at least one manipulator (20, 45, 47). The latter serves to move at least one optical component (7, 41) within the projection ray path (5, 9). The illumination angle distribution changes as a result of the controlled movement of the optical component (7, 41).

Abstract: This invention relates to a wastewater treatment process for treating nitrogen-deficient wastewater. The process enables the production of a low soluble nitrogen processed wastewater, and avoids the need for nitrogen supplementation in the wastewater treatment process. The process includes providing a supply of nitrogen-deficient wastewater to a controlled environment. The conditions in the controlled environment encourage the proliferation of nitrogen-fixing microorganisms in particular by control of the stability of the dissolved oxygen level. This process may be used alone or in conjunction with a conventional wastewater treatment process, relying on non-nitrogen-fixing microorganisms, without the need for nitrogen supplementation.

Abstract: In order to regenerate the heat exchanger material located in the various segments of a housing section (2) of a regenerative post-combustion device (1), air is heated in the combustion chamber (8) of this post-combustion device (1) by a burner (9), is directly removed from the combustion chamber (8), is adjusted to the desired regeneration air temperature using fresh air, and is returned to the inlet (4) of the thermal post-combustion device (1). The outlet (10) of the thermal post-combustion device (1) remains closed during this operation. The rotary distributor (5) of the thermal post-combustion device (1) rotates during this process which is continued until all segments of the heat exchanger material are heated to a temperature at which the contaminants absorbed by the heat exchanger materials are released and combusted in the combustion chamber (8).

The sensor further includes a leveling pad for at least partially surrounding a protruding sensor element (22, 24) to minimize protrusion of the element into the skin of a patient, and a functional liner (18) for use in pretest of the sensor prior to positioning on a patient.

Abstract: A bath tap fitting in the known way comprises a securing device which can be attached to a mounting plate. This has a securing body which extends upward and in its upper area possesses a multi-faced outer contour. An outlet spout can be fitted to the securing body with a multi-faced seating aperture so that it does not turn. A locking screw can be screwed through a threaded hole of the outlet spout against the securing body so that two faces of the seating aperture of the outlet spout, enclosing an angle with each other are pressed against two faces of the securing body enclosing a corresponding angle. In this way the securing body is “wedged” in the seating aperture of the outlet spout. The outlet spout sits absolutely firmly on the securing body.

Abstract: A regenerative post-combustion apparatus (1) in a housing (2) in a known manner comprises from top to bottom a combustion chamber (8), a heat exchanger area (7) subdivided into a plurality of segments filled with heat exchanger material, and a rotating distributor (5). The latter depending on its rotational position establishes a connection, on the one hand, between an inlet (3) for waste gas to be cleaned and at least one first segment of the heat exchanger area (7), as well as between at least one second segment of the heat exchanger area (7) and an outlet (10) for cleaned gas. Disposed above the rotating distributor (5) is a burn-out rotary slide valve (31). The latter is subdivided by dividing walls into segments, of which one is closed in the direction of the rotating distributor (5) and communicates with an outlet (68). The other segments of the burn-out rotary slide valve (31) are open in a downward and an upward direction.

Abstract: A screw-threaded joint for a pipe has a male portion (10) and a female portion (12), having complementary screw threads (11, 13). The male thread (11) extends to a position adjacent a complementary stop shoulder (18) on the female portion (12) having a recess of conical cross-section having a rounded apex. The recess is adapted to receive a head portion having a conical cross-section with a rounded apex, the radius of curvature of which is greater than that of the recess's apex providing a seal with improved stress dispersal properties upon application of torque. The wall (33) of the cone's in-use outwardly facing surface on the male portion (10) can subtend an angle of from 28-36° to the longitudinal axis of the pipe. The corresponding cone wall on the female portion can subtend an angle of from 28-38° with the same axis. The male portion (10) can comprise a second stress dispersing surface (41), concave in shape.

Abstract: A projection exposure system for microlithography that has a catadioptric projection objective and a light source is claimed. The projection objective has at least one mirror and at least one lens that are composed of specified materials. Also the positions of the mirror and of the lens within the projection objective are also specified. The material and position are specified in such a way that imaging changes in the projection objective that are due to illumination-induced change in the reflecting surface of the mirror counteract illumination-induced imaging changes in the lens. Illumination-induced imaging changes in the entire projection objective are reduced in this way.
