摘要:
The present invention relates to a heating flange, in particular for preheating air in an intake line leading to an internal combustion engine. The heating flange comprises at least one heating element for heating the air flowing past said heating element, and a body for mechanically holding and electrically contacting said heating element. For providing an improved heating flange, which is used in particular for preheating air in an intake line leading to an internal combustion engine and which guarantees fast heating of the intake air as well as increased robustness and simplified mounting, said body comprises a fastening bow having a substantially U-shaped cross-section, and said heating element comprises at least one substantially U-shaped meander loop which is fixedly connected to the base of said fastening bow.

A motor vehicle optoelectronic monitoring device includes a sensor, imaging systems, a shutter, and a controller. Each sensor element outputs a sensor element signal based on the intensity of a light signal received by the sensor element. Each imaging system is associated with a sensor region and illuminates an object to monitor the object. Two sensor regions associated with two respective imaging systems partially overlap one another. Each imaging system illuminates the sensor elements of the associated sensor region with a light signal indicative of the object being monitored. The controller controls the shutter unit to selectively enable and disable illumination of the sensor by the imaging systems. The controller processes the sensor element electric signals output by the sensor elements in response to illumination by an imaging system to determine conditions of the object being monitored by the imaging system.

A gas turbine engine for aircraft. A generator, which undertakes to supply energy for auxiliary devices, is spaced between a compressor and a turbine. A heat exchanger which surrounds the generator housing, and through which compressor air and fuel flow, is provided for cooling the generator. The compressor air which is cooled by the fuel is supplied to the rotor of the generator, and possibly to a bearing of the rotor shaft.
摘要:
A rotor for turbo engines, for example for small gas turbines or turbo-superchargers (exhaust-driven superchargers). The rotor has at least two vane wheels, and a shaft with structural elements rigidly secured thereto. The rotor, with the vane wheels and the shaft, comprises a one-piece high-quality cast part. The rotor may be mechanically or otherwise suitably machined exclusively at sealing surfaces, bearing seats, threads, follower or synchronization toothing or gearing, and other structural elements of the shaft.

The embodiments of the invention relate to a carbon brush for transmitting high currents, having a connecting element for connecting an electrical track and a consumable contact element with a contact surface that is designed to lie flush against a commutator device, wherein the connecting element and the contact element are combined in a layer transition zone aligned perpendicularly to the direction of wear of the carbon brush and form a one-piece molded body, wherein the connecting element and the contact element have different compositions, such that a carbon component of the contact element is greater than the carbon component of the connecting element and the contact element has a metal component differing from that of the connecting element.
摘要:
An automobile protection device having a first frame and a second frame. The first frame has an inner edge and an outer edge. A plurality of semi-circular tabs extend from the inner edge having circular holes. The outer edge of the first frame integrally couples the first frame with the second frame such that the first frame extends outwardly from the second frame. The inner edge of the first frame secures the license plate to the fender by aligning the circular holes of the first frame with the existing holes in a standard license plate and fender of an automobile and securing the device using screws. When in position, the device extends perpendicularly outwardly from the fender to prevent damage to the license plate and fender of an automobile.

The aim of the invention is reduce the damage to material containing cellulose during the bleaching thereof, by using bleaching catalysts, without significantly affecting the bleaching performance. This is achieved essentially by a method for the bleach treatment of material containing cellulose in the presence of a bleaching agent containing peroxygen and a bleach-enhancing transition metal complex, said method being carried out in the presence of a saccharide polymer carrying carboxy groups.
