Patent DE-3116421-A1 (DE)
Title: Method for generating a signal to initiate the cleaning of functional units in a non-mechanical printer or copier
Inventor: MUGRAUER HUBERT DIPL ING
IPC: G03G15/02
Filed: 1981-04-24
Abstract: In non-mechanical printers or copiers, in which charge images are developed with the aid of toner, there is the risk that functional units required for generating the powder images become polluted by the toner. Such functional units are, e.g., the transfer corotron, the charging corotron and the developer station. Faultless printing therefore requires these functional units to be cleaned from time to time. A method is specified according to which a signal is produced when the cleaning of these functional units has to be carried out. This signal for cleaning the functional units is generated when a fixed number of sheets of the recording carrier to be printed have been printed, or when the distance from the recording carriers to the edges of transporting feed means is altered to match the width of the recording carrier. The signal is extinguished when cleaning of the functional units has been carried out.

Title: Heat-insulating composite panel
Inventor: VORINGER KONRAD
IPC: E04C2/24
Filed: 1981-04-24
Abstract: A heat-insulating composite panel composed of individual panels which are adhesively bonded together and are provided with tongue and groove for placing them side by side is proposed. In the known composite panels, the tongue and groove are located in an outer individual panel which is designed as a rigid panel of relatively high thickness and correspondingly high weight. By contrast, the composite panel according to the invention comprises three individual panels, specifically the outer rigid individual panel and two panels of foam plastic which are adhesively bonded together such that, by offset of the centre panel (2) with respect to the other two individual panels (1, 3), the tongue (4) and groove (5) are present between the outer individual panels along two mutually adjacent edges in each case. The composite panel is very lightweight because the rigid outer panel can be kept relatively thin and is suitable in particular for producing a heat-insulating cladding of walls, ceilings and floors. <IMAGE>

Title: Arrangement for subtracting X-ray images
Inventor: EDELHEIT LEWIS SELIG
IPC: H04N5/32
Filed: 1981-08-11
Abstract: In the X-ray image subtraction arrangement, in which a sequence of visible X-ray image pairs is obtained in rapid succession, a different voltage for each image of a pair being applied to the X-ray tube (13), a video camera (26) is used for converting the pixels of each image into analog signals which are supplied to an A/D converter (28). The resultant digital signal representations of the images of a pair are connected to a first and, respectively, second store (30, 31). A processor (33) transfers the contents of each store (30, 31) into a video disc recorder (37) during the relatively long interval between X-ray pulse pairs. The processor (33) subtracts the digital signals representing the images in each pair. The results of the subtraction are converted into analog video signals in order to enable a relatively long sequence of images to be displayed on a video monitor (40). <IMAGE>

Title: Measuring cardiac blood oxygen saturation for pacemaker regulation - using measurement probe with lead and phototransistor in parallel
Filed: 1981-02-26
Abstract: The appts. determines the degree of oxygen saturation in blood within the heart, using the principle of reflective oximetry, so as to regulate the frequency of a cardiac pacemaker. An opto-electronic measurement probe is integrated in the stimulation catheter and a measurement amplifier in the pacemaker, the probe containing merely a single l.e.d. (32) and a phototransistor (37) switched in parallel. Light emitted from the diode is reflected back to the phototransistor by blood (44) depending on the degree of oxygen saturation.       The current (GK delta Is) generated by the phototransistor is superimposed on the forward current (Is) through the l.e.d. so that a change in the voltage or current flowing through the probe is effected. The measurement amplifier in the pacemaker processes the magnitudes so as to separate and amplify the signal components not conditioned by blood reflection.

Title: X-ray fluorescent supplement for electron-beam apparatuses
Inventor: ECKERT RICHARD DIPL PHYS
IPC: H01J37/252
Filed: 1982-02-26
Abstract: The X-ray fluorescent supplement facilitates the illumination of items under test with X-ray radiation in electron-beam apparatuses. The X-ray fluorescent spectrum emitted from the item under test in this case includes a greatly reduced scatter background in comparison with X-ray excitation by electrons. In consequence, even trace elements can be found in the item under test during X-ray material analysis. In the X-ray fluorescent supplement, the item under test and the solid target (anode) are arranged in two separate chambers. An opening between the chambers is covered with plastic film. This allows the X-ray radiation from the anode to pass through but holds the scatter electrons back.

Title: Transport system for local public passenger transport
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: B61L23/00
Filed: 1982-09-24
Abstract: The invention relates to a transport system for local public passenger transport with vehicles of different sizes which can be used on rails and with a corresponding track network. In order to match the vehicle size, appropriately to requirements, to the passenger volume which changes according to the time of day, a plurality of train-formation stations are distributed along the lines in the track network and connected, in each case independently, to the vehicle depots via separate train-formation tracks which are free of junctions along their course. The vehicles and also the train-formation tracks are constructed in such a way that the vehicles can be directed unmanned from the depots into the train-formation stations or vice versa. By virtue of the arrangement of the train-formation stations near to the tracks, preferably on each transport line, it is possible to change the vehicles without difficulty and quickly during scheduled services and thus to easily match the vehicle size to the changing passenger volume appropriately for requirements.
