Abstract: The invention relates to a device (10) for hardening an UV varnish and thermohardening varnish or the similar for coating an object, in particular a motor car body (12) comprising at least one emitter (48, 48?) generating electromagnetic radiation. The inventive device is provided with a conveying system (14, 16) which conveys the object (12) closely to the emitter (48, 48?) and, afterwards removes it. Said conveying system comprises an overhead travelling carriage (16) which is translatory displaceable along at least one guideway (14) suspended above at least one emitter (48, 48?). Two suspension supports (66) extending downwards and making it possible to suspend the object (12) are arranged successively in a longitudinal direction (85) on a chassis (50) of the travelling carriage (16). The length of said suspension supports is individually modifiable with the aid of a motor.

Abstract: The invention relates to a device for guiding powdery fluidic media, in particular powder paint, including a receptacle which is provided with an inner chamber for the media which is to be guided, and from where the medium is suctioned via a connection channel which can be closed by a valve body. The connection channel and the valve body comprise, respectively, an upper end area. Said upper end areas are formed in such a manner that an annular Venturi nozzle is formed therebetween which is used as a pump. The valve body is inserted in a sealed manner in the end region of the connecting channel by means of a sealing section when in the closed position thereof and comprises a conveyor gas channel which can impinged upon by conveyor gas, through which the conveyor gas can be guided to the connection channel in the vicinity of the sealing section, essentially, in the direction of flow of the medium.

Abstract: The invention relates to a device for controlling the temperature of objects, especially for drying or cooling objects, said device comprising a housing containing at least two tempering units which are arranged in a functionally parallel manner. Each tempering unit comprises a tunnel-type usable space in which tempered air is applied to the objects. Said objects can be displaced through the usable spaces by means of a respective transport system. According to the invention, the at least two tempering units are superimposed in the housing essentially above the same base surface.

Abstract: The invention relates to a serial data bus including a data line for transmitting electrical signals representing bit states and a plurality of multi-master subscribers between which messages can be exchanged via the data line in an event-driven manner according to the broadcast principle. At least two subscribers have a transceiver head, inductively connected to the data line, via which contactless electrical signals are picked up from the data line or transferred thereto. An amplifier (is galvanically connected to the data line and is adapted to receive electrical signals that have been inductively transferred by the at least two subscribers to the data line and to feed them back to the data line once amplified. Due to its inductive connection, the data bus is especially low-maintenance and also suitable for hazardous surroundings.

Abstract: The invention to a system which is used to dry objects, comprising a drying cubicle (1), known per se, wherein the objects are exposed to hot air. The process waste air from a high temperature fuel cell (10) is used as hot air which is directly introduced into the drying cubicle (1). The high pressure fuel cell (10) is operated, according to thermal energy required for the drying process, whereby according to the extent thereof electric energy is also accumulated and is disregarded when controlling the high temperature fuel cell (10), whereby electrical consumers for said electrical energy can always be found. The inventive system and method for drying objects are relatively inexpensive and have a very high energy utilisation ratio.

Abstract: An apparatus for treating articles, in particular vehicle bodies, with at least one tempered, directed air jet comprises a housing, in which are formed a treatment chamber and at least one pressure chamber, which is separated from the treatment chamber by a partition wall. The tempered air is suppliable to the pressure chamber and may then flow as a directed air jet into the treatment chamber through a nozzle device, which penetrates an opening of the partition wall. The nozzle device is insertable from the treatment chamber into the partition wall and fastenable from the treatment chamber to the partition wall. Consequently, subsequent work on the nozzle device, in particular an exchange thereof, may be carried out more easily.

Abstract: A device with which electrical energy can be transferred from a power cable running along a stationary rail of a transport system to a moving element that can be driven along the rail. Each moving element has for this purpose a transfer head which works inductively together with the power cable. The power cable is attached with the aid of carrier profile which extends substantially along the entire length of the rail and is fixed in a releasable manner to the rail, which element has at least one a trough-like holder open to the side in which the power cable is laid. The power cable is thus relatively easily and accurately laid, avoiding hanging loops of cable which could be damaged by abrasion by the passing transfer heads of the moving elements.
