Abstract: The invention relates to an arrangement for microwave radiation of materials, in particular of the starting materials for ceramic materials, alloys etc., having a conveying path that is defined at least in part by a trough or pipe arrangement, the wall of which has a specific microwave-absorption capacity, a resonator surrounding at least a length of the wall, and at least one generator for generating the microwave radiation. In order to enable adjustment of the heating and the radiation dosing of the microwave-treated materials independently of one another, it is proposed according to the invention that the wall of the trough or pipe arrangement (1; 9.1 to 9.3) has different microwave-absorption properties along its length.

Abstract: A heat shielding cladding for walls, ceilings, or similar surfaces, especially of industrial furnaces, including butted together parallelepipedal modules that are secured to the wall and comprise a plurality of held together and compacted fiber mat webs that are prestressed in a direction parallel to the wall. Adjacent modules are held together in a permanently flexible bond on non-prestressed sides thereof by at least one filamentary, temperature-resistant binder that is guided, without kinking, from a surface of the heat shielding cladding that is remote from the wall to the wall.

Abstract: A hose nozzle for filling fluid into a tank and for shutting off automatically when the tank is filled is provided. The hose nozzle comprises a housing that has an inlet nozzle and an outlet pipe at opposite ends of the housing and a grip portion of an area of the inlet nozzle. A flow valve is disposed in the housing between the inlet nozzle and the outlet pipe whereby the flow valve further comprises a valve rod. A control device is provided that comprises a pressure channel and a plunger-type control element, for closing the flow valve depending on a pressure present in the pressure channel, against a direction of fluid flow, whereby the control device is disposed in the housing between the inlet nozzle and the flow valve and whereby the pressure channel is connected to a port of the outlet pipe. A manual lever, disposed within the grip portion and connected with one end thereof to the control device, actuates the flow valve and controls a fluid flow from the inlet nozzle to the outlet pipe.
