摘要:
A method and apparatus for calcining an aluminum hydroxide source to an aluminum oxide in which the amount of the .alpha.-modification can be controlled from very low to very high values. In accordance with the present invention, the calcination of the source material takes place in two stages, in the first of which the material is preheated with air and then passed to a fluidized bed calciner after which it is delivered to a holding cyclone. In the second stage, the previously calcined material which may contain up to about 80% of the .alpha.-modification is calcined further in a rotary tubular kiln which is followed downsteam by a cooler.

The invention also relates to a method of heating an appliance and to a method of providing a heating element.
摘要:
A multifunctional strip for a motor vehicle includes a panel element having a strip-shaped configuration and constructed for outputting first and second items of information which differ from one another; and at least one actuator for outputting an acoustic signal as one of the items of information. The multifunctional strip can be arranged on the outside of the body of the motor vehicle.
摘要:
An arrangement for covering a component, in particular a steering wheel rim, of a motor vehicle, which component has an in particular encircling fastening depression. The arrangement has a cover composed in particular of a flexible and/or non-slip material, and at least one fastening element, in particular a clamping element, for fastening the edges of the cover, which is placed around the component, in the fastening depression. The at least one fastening element is designed as a light source and/or has at least one light source.
摘要:
A lighting device for a motor vehicle includes several flat light-conducting elements that are arranged in layers one behind the other in a layer arrangement. The individual light-conducting elements do not touch one another and are clearly spaced apart from one another. Each of the light-conducting elements includes a light-scattering structural element. An illuminating device is optically coupled to each of the light-conducting elements in order to couple light into the light-conducting elements. Light is coupled out of the light-conducting elements by means of the structural elements.
摘要:
A lighting device has a first panel, which has an underside and an upper side, and a plurality of lighting elements which illuminate the first panel from the underside. The first panel has a plurality of transparent and non-transparent elements which are arranged one adjacent to the other in an alternating fashion and which each extend completely from the underside to the upper side. The lighting elements are controlled by a control device which is designed to bring about a predefinable spatial brightness profile in a space on the upper side of the first panel.
摘要:
The present invention relates to an iontophorectic device and a composition comprising active ingredients for the transdermal release of active ingredients, particularly of human insulin. Insulin, a blood sugar-lowering hormone inhibiting glycogen breakdown of the pancreas, can be made available as the most important pharmaceutical for the therapy of diabetes mellitus via the transdermal resorption route.
摘要:
A movable objective lens assembly that includes an infinity-corrected objective lens providing the microscope with an optical field of view. The assembly permits the imaging of a specimen under investigation over an area of the specimen much larger than the field of view of the objective lens without moving the microscope and/or a specimen stage relative to one another. The assembly includes a mirror system and the linearly movable infinity-corrected objective lens. The mirror system includes a plurality of mirrors that provide a folded optical path that allows the objective lens to be moved relative to the specimen without moving the entire microscope. The mirror system and the objective lens are pivotably mounted relative to the rest of the microscope so as to allow the objective lens to be located substantially anywhere within a circular, or circular-sectoral, viewing area.
