Patent DE-2948048-A1 (DE)
Inventor: WUENNING JOACHIM DR ING
IPC: F23D14/78
Filed: 1979-11-29
Abstract: In order to permit operation with preheating of the combustion-supporting air to 50 or preferably 65 percent or more of the oven temperature, the air is fed to a ceramic burner tube through an annular nozzle directing it in an annular jet along the interior walls of the burner tube. For a burner of low back pressure having no restriction at the mouth of the ceramic burner tube, the ceramic burner tube fits over the end of the outer member of the annular nozzle and some of the combustion product gas, flowing from the oven into the burner structure for countercurrent of the preheating of the air supply, is sucked into the underpressure zone between the annular air jet and the inner wall of the burner tube through a small annular gap where the burner tube fits on the air-supply nozzle. For a burner design involving considerable back pressure, the ceramic burner tube fits within the outer wall of the annular nozzle with a very small clearance in the overlap and some of the supplied air, which is at higher pressure than the exit in gases, escapes through the gap around the outside of the burner tube and cools the burner tube and the adjacent overlapping portion of the air supply tube.

Title: Device for the releasable connection of two hollow-profile bodies
Inventor: FUCHS THEO
IPC: F16B7/04
Filed: 1981-01-23
Abstract: For the releasable connection of a hollow-profile body (1) to a hollow-profile rail (2), the invention provides a clamping bolt (3) which can be rotated and displaced in the axial direction and has an anchoring head (12). The clamping bolt (3) is seated movably in a bearing body (4) which is introduced into bores of the hollow-profile body (1). Into the bearing body (4) there is introduced a rotary peg (5), into the longitudinal groove (7) of which there projects an adjusting pin (6) protruding from the clamping bolt (3). When the rotary peg (5) is rotated - starting from the non-clamped position - the clamping bolt (3) is first of all ejected and engages into the longitudinal groove (15) of the hollow-profile rail (2). A further rotation of the rotary peg (5) causes the clamping bolt (3) to pivot, with the result that it adopts a transverse position. When the rotary peg (5) is further rotated, a returning and clamping movement of the clamping bolt (3) takes place. In order to secure the clamping position, a pressure screw (20) is pressed against the clamping bolt (3). This connection device makes possible the clamping connection of two hollow-profile bodies with the aid of clamping bolts (3) without mutual pivoting of the two parts in order to be able to introduce the anchoring head (12), by its narrow side, into the longitudinal slot (15). <IMAGE>
