A filter device for filtration of gaseous fluids has a multi-part housing with a first housing part and a second housing part connected to one another in a mounted state of the multi-part housing. A filter element is insertable into the multi-part housing. A connecting device penetrates the filter element and provides a connection between the first and second housing parts. The connecting device has at least one first housing projection monolithically formed on the first housing part. The connecting device further has a damping element arranged between the at least one first housing projection and the second housing part.

摘要:
An apparatus for safely operating at least two components which are movable relative to one another in a machine for processing printing materials, includes drive motors each driving a respective one of the movable components. At least one control computer detects movement of the movable components. The control computer is set up in such a way that, if a spacing is reduced between the movable components, at least that movable component, which is the cause for the reduction in the spacing between the movable components, is brought to a standstill. A printing press having the apparatus is also provided.
摘要:
A general method is given for screening laser diodes for electrostatic discharge, (ESD), damage. The laser diode may be selectively isolated from the laser driver so that a current-voltage (I-V), curve can be taken and then compared to curves taken previously on the same laser diode to ascertain the possibility of ESD damage. Presumably the initial I-V curve will be representative of the characteristics of that particular laser in the undamaged state. Such an initial curve may be supplied by the manufacturer and may be a curve specific to a particular laser diode. Comparison with a standard curve is not sufficient to determine ESD damage in the early stages of failure. Some embodiments focus on isolating the laser diode from the laser driver, storing the information locally in the transceiver, and providing some analysis resulting in flagging laser diodes showing changes that are indicative of ESD damage.
摘要:
A cover for a cylinder head of an internal combustion engine having a connecting element for attachment the cylinder head and a sealing element arranged between the cylinder head cover and the cylinder head. The connecting element is associated with a connecting area, and the sealing element is associated with a sealing area. The connecting area and the sealing area are constructed independently of each other and are spatially separated from each other, and the force vectors of the connecting force transmitted by the connecting element and the sealing force transmitted by the sealing element form an angle with each other.
摘要:
An optical transceiver device having digital and programmable control over transceiver components is disclosed. The optical transceiver module comprises a controller and an integrated post-amplifier/laser driver (“PA/LD”), which are included on a printed circuit board disposed in the module. Transmitting and receiving optical sub-assemblies for transceiving optical signals are also disposed in the module. A digital signal interface interconnects the controller with the integrated PA/LD. A microprocessor is interposed between the controller and the PA/LD and is connected to both components via the digital signal interface. Digital control signals produced by the controller are transmitted via the digital signal interface to the integrated PA/LD where they are converted to analog signals for use by a plurality of control amplifiers. Conversely, analog feedback signals produced by the control amplifiers are converted to digital signals and transmitted to the controller. The microprocessor can intercept, analyze, and modify the digital control and feedback signals for optimum use by the controller or integrated PA/LD.
