Abstract: AN OIL OR GAS BURNER HAS A CASING FORMED BY A LOWER CASING MEMBER AND A COVER PLATE FORMING AN ELONGATED CASING WITH ROUNDED ENDS.. A BLOWER ROTOR IS LOCATED IN AN OPENING IN ONE OF THE ENDS, THE CASING WALL ADJACENT THE OPENING FORMING A GUIDE PLATE AT THE INTAKE SIDE OF THE ROTOR. THE ANGLE BETWEEN THE TANGENT TO THE CASING WALL AT THE BEGINNING OF THE GUIDE PLATE AND THE TANGENT TO THE CASING WALL AT THE OTHER END OF THE ROUNDED END PORTION IS LESS THAN 90*, PREFERABLY 30*-60*. THERE IS PROVIDED AT THE OTHER SIDE OF THE ROTOR FROM THE GUIDE PLATE, WHERE THE ROTOR IS SLIGHTLY SPACED FROM THE LONGITUDINAL WALL OF THE CASING, A VORTEX BAFFLE-PLATE WHICH TAPERS IN CROSS-SECTION TOWARDS THE PERPHERY OF THE ROTOR, AND BETWEEN WHICH AND THE END PORTION OF THE LONGITUDINAL WALL ONE OR MORE PASSAGES ARE FORMED THROUGH WHICH SOME OF THE AIR FED BY THE ROTOR CAN BE RETURNED FROM THE PRESSURE-SIDE TO THE SUCTION-SIDE.

Abstract: An arrangement for regulating the temperature inside a vehicle includes a casing containing a heat exchanger and a transverseflow blower for moving air through the heat exchanger. The blower includes an impeller and the casing has a guide wall opposite the impeller which starts at a point close to the impeller and extends in a spiral of increasing radius through an angle of about 180* around the impeller axis and has a continuation tangent to its end remote from the impeller. A wedge-shaped vortex-forming tongue has a surface on its suction side which faces the impeller and forms therewith a passage diverging in the direction of impeller rotation. A guide plate opposite the surface of the tongue on the suction side forms with such surface a channel which converges from the discharge side towards the suction side and runs approximately tangential to the periphery of the impeller.

Abstract: A dryer for particulate or fibrous material includes a flow path in which a fan conveys fresh air. The flow path includes a combustion chamber for producing hot gas and a heat exchanger receiving the hot gas, as well as a drying zone which receives the heated air for drying the material in the zone. The fan is a crossflow fan, including a cylindrical impeller, a curved deflector plate and a turbulence flap. The deflector plate diverges circumferentially from the impeller in the direction of the rotation and encloses the impeller for an angle of about 180*. The tangents to the deflector plate at the circumferential ends enclose an angle less than 90*. The turbulence flap has a surface on the suction side which forms with the impeller circumference a channel widening in the direction of rotation of the impeller, which forms an acute angle with a surface of the flap on the pressure side. The channel provides a partial return current of air to the impeller from the pressure side in a direction substantially tangential to the impeller circumference. The axial length of the impeller is considerably greater than the diameter. The impeller combustion chamber and heat exchanger are contained in a casing of a width corresponding substantially to the length of the impeller. Bearing and drive units for the impeller are located outside the casing.

Abstract: A fuel burner has a spray nozzle with fuel feed means and a blower for producing a flow of combustion air to the nozzle. The device includes a return line returning from the nozzle to the fuel source and a valve in this line which is controlled by comparing the actual value of the fuel flow or air flow with a predetermined desired value. The fuel flow is measured by a device which is connected both to the inlet and return lines of the fuel nozzle.

Abstract: A BAND OR WEB OF MATERIAL OR A LAYER OF MATERIAL CARRIED ON A BAND IS TREATED BY EXPOSING THE SURFACE OF THE MATERIAL WHILE PASSING IT THROUGH A TREATMENT CHAMBER TO JETS OR A CURRENT OF AIR, THE JETS IMPINGING ON THE SURFACE AND FORMING A FLOW TRAVELING ALONG THE SURFACE OF THE MATERIAL THE FLOW IS REPEATEDLY INTERRUPTED ON ITS COURSE AND THEN REFORMED BY PRODUCING AN INSTABILITY IN THE FLOW, AS BY THE USE OF SPOILERS. THE FLOW MAY BE PRODUCED BY CROSSFLOW BLOWERS WITH THEIR AXES PARALLEL TO THE SURFACE OF THE MATERIAL, DISCHARGING DIRECTLY INTO THE SURFACE OF THE MATERIAL. THE OUTLET OF THE BLOWERS IS VARIED BY MOVABLE FLAPS.
