Title: Controller for a window-envelope folding device
Inventor: WAGNER BURKHARD
IPC: B31B19/26
Filed: 1984-05-11
Abstract: The invention relates to a controller for a device for folding an envelope-window fold for use on buckle-folding machines, it also being possible to use the said device as a special accessory. The invention is based on the object of creating a controller for a window-envelope folding device, which controls the time movement sequence of the various sheet guiding devices in accordance with the values entered from a central point, as a function of the position of the sheet which is respectively to be folded, such that high quality of the window-envelope fold is achieved. According to the invention, at a defined point inside the pocket-folding mechanism, a clearly defined point on the sheet which is to be folded is detected by a sensor, which is fitted in a stationary manner, and the distance to be travelled by the sheet is measured from this point. In the case of a signal sequence which is preferably selected to be "light-dark" a counting process is triggered by the sensor, via one pulse. A further pulse transmitter likewise supplies pulses which are dependent on the machine speed to an electronic evaluation unit which consists of a plurality of modules and operates the actuating elements of the upper and lower sheet guiding elements.

Title: Axle suspension for motor vehicles, especially passenger motor vehicles
Inventor: SCHELLER FRANZ X DIPL ING
IPC: B60G9/00
Filed: 1984-07-31
Abstract: An axle suspension for motor vehicles is proposed, the rigid axle of which does not perform any kinematically induced bump steering movements in the event of compressions and rebounds and in the case of compression movements essentially deflects in the direction of a shock produced by running over an irregularity on one wheel (positive oblique suspension). For this purpose the rigid axle is on the one hand guided in the vehicle's longitudinal direction by means of two control arm arrangements, advantageously four-bar linkage mechanisms, arranged at a lateral distance from one another so that their coupling points on the rigid axle side, height-offset in relation to the wheel axle, are displaced in a vertical plane lying perpendicular to the vehicle's longitudinal direction in the event of compressions and rebounds. On the other hand the positive oblique suspension is achieved by a guide arm acting on the rigid axle, by means of which arm the rigid axle and a swivel axis defined by the coupling points is swivelled in the event of compressions and rebounds.

Patent DE-3433704-A1 (DE)
Title: Screw-in throttle-valve kit
Inventor: BRUNNER RUDOLF
IPC: F16K47/10
Filed: 1984-09-13
Abstract: The invention relates to a screw-in throttle-valve kit with at least one screw-in valve body for a threaded hole of specified dimensions and screw-in depth which, with a throttling seat, leads axially to a first flow passage and into which a second flow passage opens at the side, with a throttling cone which interacts with the throttling seat, and with an axial hole in the throttling cone, which hole can be separated from a lateral passage in the screw-in valve body by way of a nonreturn valve comprising a spherical closing element and a valve seat arranged on that side of the closing element which faces the axial hole. Known screw-in valve bodies can only be used for one valve function. It is not possible to reverse this valve function. According to the invention, reversal of the valve function is possible by virtue of the fact that a screw-in valve body, in which the nonreturn valve is a plate-type nonreturn valve with a shut-off direction opposite to that of the ball-type nonreturn valve of the other screw-in valve body, is provided, this screw-in valve body being interchangeable with the screw-in valve body with the ball-type nonreturn valve and having the same outside dimensions.
Patent DE-3435538-A1 (DE)
Title: Method for reproducing original documents
Inventor: HANUS ROBERT
IPC: G03F3/08
Filed: 1984-09-27
Abstract: The present method for reproducing original documents is intended to provide a scanner operator with an objective capability for determining the brighest and the darkest point on an original document and to be able to carry out a colour correction. For this purpose, the original document, before being reproduced, is resolved into a predetermined data recording raster which is coarser than the raster of the production raster program by means of which the scanner resolves the original document. After that, each data recording raster dot is analysed for its brightness value and the brightest and the darkest point is determined. Furthermore, the distribution of brightness is determined, evaluating all data recording raster dots. Finally, this brightness distribution is used for influencing the correction of the colour signals on the scanner. For the purpose of colour correction, selected pixels can be spectrally analysed with regard to a predetermined number of spectral bands. The spectral distribution curve which can be determined by this means can be compared with distribution curves which are generated by analysing the printing colours. The printing colour distribution curve with the closest approximation is then determined and the primary colour values for the selected light spot are determined. The colour signals can then be corrected.
