Abstract: ABSTRACT OF THE DISCLOSURE     In an optical network system comprising a plurality of communication stations and a star coupler common to the stations, a collision test signal is produced from a generator included in a transmitter section of each station to be sent to the star coupler prior to transmission of a data sequence and is directly returned from the star coupler to a receiver section thereof.  The receiver section comprises a detector for monitoring the collision test signal to detect occurrence of collision.  The detector makes the transmitter section inter-cept the data sequence on occurrence of the collision.  Prefer-ably, the collision test signal is encoded by an encoder  in the transmitter section to be combined with a snychronizing signal and is decoded by a decoder in the receiver section.          Such stations may be coupled to the star coupler through a concentrator and a distributor or may be divided into a plurality of groups each of which is accommodated in a network unit linked through a repeater to the other in a loop.

Abstract: ABSTRACT OF THE DISCLOSURE A modular unit as a filtering apparatus for a membrane separation process, especially for treating water by reverse osmosis.  The apparatus comprises a pipe which is open at both ends and in which can be inserted a stack of membranes which is adapted to the inner diameter of the pipe.  The stack of filter elements, which comprises guide plates, carrier plates, and membranes, is clamped together by a central clamping both which passes through the filter element stack between two fixed pressure plates.  Located at the peripheries of the pressure plates are inclined circumferential grooves in which are disposed sealing rings which, when excess pressure exists in the interior of the housing, are urged radially and axially outwardly, and thus effect a good seal between the inner wall of the pipe and the peripheries of the pressure plates.

Abstract: ABSTRACT        A method and apparatus for isochromatic simulation of a multi-colored reproduction on a color monitor.  Before simulation, colors are generated on the color monitor and are matched to corner colors of a printed color chart or the like by measuring or visual comparison.  The color values required for the chromatically coinciding generation of the corner colors on the color monitor are measured and allocated to color separation values of the corner killers The color values required for venerating intermediate colors are calculated upon consideration of the printing process of the multi-colored reproduction and are allocated to the corresponding color separation values of the intermediate colors.  During the simulation, the color separation values of the multi-colored reproduction are output, modified according to a gradation curve, and transformed into the color values for driving the color monitor in accordance with the previously identified allocations.

Abstract: Abstract of Disclosure A simplified, relatively inexpensive laser device, wherein the laser elements are fixed in a body exoskeleton of electrical insulating material having a low coefficient of thermal expansion. The preferred embodiment includes a shotgun type laser filter having parallel bores which receive the laser flashlamp and laser rod in fixed relation in a body chamber. The reflector surrounds the laser filter and retains the filter within the body chamber. In the preferred method of this invention, several controlled lasing pulses are generated with each illumination pulse of the flashlamp, substantially increasing the efficiency of the laser device. The number of pulses is generally controlled by increasing the voltage to the flashlamp. The rapid multiple lasing pulses generate an elongated plasma in a fluid medium, such as the vitreous fluid body of an eye which makes the laser device extremely efficient for treating glaucoma and other medical treatments.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a control device and process for aligning,  in the running direction,  an endless belt.        The  device  comprises  a  lifting  cylinder  with  a ram which is retracted or extended as a result of switching signals received from microswitches via a control cir-cuit.  The device further includes a pivotal wing which is pivoted by the extending ram in the running direc-tion A of the belt, and a deflecting roller having an axle,  the ends of which are mounted in the eyeparts of eyebolts.    During  pivoting,  the  wing  presses  one eyebolt, resting by means of its bolt end against the front side of the wing, in the running direction A of the belt.  The axle, mounted by means of its axle end, with a certain play in the eyepart of the other posi-tionally fixed eyebolt,  is pivoted as a result. As coon as the belt runs out of alignment, that is to say deviates from the running direction A, one of the belt edges  actuates  the  associated  microswitch and  con-sequently the lifting cylinder.   As a result of the pivoting of the axle of the deflecting roller, the non-aligned running of the belt is constantly counteracted and the belt is deflected counter  to the nonaligned direction until it actuates the other microswitch.
