Title: Method for non-intermittently proceeding printing in flat screen printing machines and device to carry out the method
Inventor: STELZL ALEXANDER
IPC: B41F15/08
Filed: 1988-09-20
Abstract: A method for a non-intermittently proceeding printing operation in an automatic screen printing machine, namely a flat-bed automatic printing machine, preferably having a plurality of printing units is described, to which the paper to be printed is fed as a continuous web from a paper roll. In this case, each printing unit is designed as a tandem printing unit. The individual printing units are actuated in such a way that a first squeegee/screen frame arrangement is printing while, at the same time and alternating therewith, a second squeegee/screen frame arrangement is flushing the screen having its associated motif or the like in opposition to the printing or paper web movement, and vice versa. The continuous run of paper is predetermined by means of simultaneous control of the opposing screen frame movements and can be adjusted precisely in this manner.

Title: Method and measuring device for the determination of the attenuation properties of sound absorbing installations
Inventor: HAUSER GUENTHER PROF DR ING
IPC: G01H3/04
Filed: 1988-09-23
Abstract: The configuration of sound absorbing installations, especially for internal combustion engines, is a complex acoustic and fluidic problem. Carrying out measures to improve the attenuation properties is made more difficult in that, in the case of measurements being undertaken in real operation and carrying out the alterations on sound absorbing installations, a cooling and heating of the absorbing system occurs or must be waited for, respectively. The invention allows the determination of the attenuation properties of sound absorbing installations to be carried out at ambient temperature, in that a measure of the frequency shift in the frequency spectrum between the excitation of the sound absorbing installation at operating temperature and at the ambient temperature is determined and this measure of the frequency shift is taken into account in the case of acoustic excitation at ambient temperature. In this case the acoustic excitation may be converted to the operating temperature by means of the previously determined measure of the frequency shift or the measured values can be recalculated to operating temperature, taking into account the measure of the frequency shift.

Title: Connecting device for contactor coils
Inventor: BAUER JOHANN DIPL ING
IPC: H01R4/34
Filed: 1989-01-19
Abstract: Known connecting devices have connecting rails which are provided with a thread into which connecting screws are turned. These connecting screws are either not secured against being lost or they are secured against being lost in the installed state by axial peening over. However, this leads to the screws bending. In addition, production is relatively costly. According to the invention, the connecting thread is no longer provided in the connecting rail but in a separate nut. The nut can be peened over on the outside with the screw in the normal manner. The unit formed by the screw, nut and spring washer is then inserted into a connecting block and the connecting rail is pushed on by means of a slot between the nut and clamping washer, as a result of which the connecting screw is also protected against falling out. The connecting device according to the invention is particularly suitable for the coil connections of relatively large contactor coils. <IMAGE>

Title: Process for treating exhaust gases
Inventor: HEINRICH GUENTER PROF DR
IPC: F24H4/02
Filed: 1989-02-22
Abstract: The invention relates to a process for treating exhaust gases, preferably flue gases or hot and moist gases from technological processes, a heat pump having a non-azeotropic two-component refrigerant being used. The evaporator arranged in the exhaust gas stream is flushed with some of the condensate arising by collecting it and circulating it. By addition of additives, other toxic gases can be eliminated. The condensation of the refrigerant mixture is carried out in two separate condensors. The more readily boiling refrigerant component is liquefied in a gas-impinged condensor and serves for the secondary heating of the exhaust gas and the second refrigerant component is liquefied in a water-impinged condenser and enables heat to be given off in an external heating circuit.

Title: Foldable handlebars
Inventor: TUPATH WALTER DIPL ING
IPC: B62K21/16
Filed: 1989-03-13
Abstract: In bicycles, once the handlebars have been chosen the height of the handlebars and hence the distance of the handgrips from the carriageway are fixed. When the handlebars are low-lying or the handgrips have been pulled a long way down, the cyclist finds this uncomfortable and this leads to the cyclist riding in an upright body posture without his hands on the handlebars, particularly when cycling slowly. Foldable handlebars are proposed as an addition to the handlebars which can be used to change the height of the handlebars even whilst cycling (Fig. 1). <IMAGE>
