Patent DE-3707921-A1 (DE)
Title: Medical treatment device
Inventor: KUBOTA TETSUMARU
IPC: A61B17/00
Filed: 1987-03-12
Abstract: A medical treatment device for resection of tissue in a live organism utilises ultrasonic vibrations for the purpose. It comprises an ultrasonic resection unit (1) which contains an ultrasonic vibration generator (4) and a probe (26) which is connected to the ultrasonic vibration generator (4) for transmission of the vibrations generated by the ultrasonic vibration generator (4). The probe (26) has a distal end-section for transmission of the vibrations to the tissue. The device furthermore comprises a haemostatic device (37) with a haemostatic member (37A) located in the vicinity of the distal end-section of the probe (26). The haemostatic device (37) quickly stops any bleeding that occurs during resection. <IMAGE>

Title: Forced circulation cooling system
Inventor: REIFENSCHEID OTTO
IPC: F01P7/16
Filed: 1987-03-14
Abstract: The invention relates to a forced circulation cooling system for a supercharged internal combustion engine, having a circuit branch in which the internal combustion engine is situated - high temperature circuit - and a circuit branch in which one or more charge air coolers and an aftercooler - low temperature circuit - are situated. Coolant for both circuit branches is drawn by means of separate feed devices from a common chamber and also returned there for thorough mixing. By arranging a connecting line between engine feed and return lines in conjunction with a separate feed device in the high temperature circuit, hot coolant from the engine outlet can be added to the cooler coolant drawn from the common chamber. Coolant is thereby available at the engine inlet, the temperature of which is high enough for optimum operation of the internal combustion engine, it being possible, however, for the temperature level in the mixing chamber to be lower. This also results, however, in optimum cooling of the charge air in any operating mode of the internal combustion engine. With additional cooling in the aftercooler of the coolant drawn from the mixing chamber, sufficiently low temperatures can also be generated in the upper power range. Despite the simple construction of the cooling system with thorough mixing of the coolant flows from different branch circuits and only one aftercooler, the temperature and flow rate in the different circuit branches have no influence on one another. <IMAGE>

Title: Process for producing an electric roller-type or film capacitor
Inventor: EDLER WOLFGANG
IPC: H01G4/32
Filed: 1987-03-24
Abstract: In a process for producing an electric roller-type (paper) or film capacitor which can be adjusted to a set value after its completion, use is made of a capacitor structure which comprises dielectric films and electrodes lying alternately one on top of the other. The oppositely poled electrodes are led to different end faces and bonded there by sprayed-on metallized layers. At least one electrode is formed by a metal layer which is applied to a dielectric film and has a variable conductivity perpendicularly to the longitudinal direction of the film. After completion of the capacitor structure, an a.c. voltage which is higher than the nominal voltage and the spray-commencing voltage is applied until the desired capacitance is achieved. <IMAGE>

Title: Image processing memory device
Inventor: HOSODA MAKOTO
IPC: G06F12/02
Filed: 1987-08-26
Abstract: The invention concerns an image processing memory device for numerical control systems. The address signals for the pixels, which are stored in an image memory, are generated serially for each point, and each item of image information is read sequentially into a central processor unit or similar, to obtain specified quantities of values. This method is comparatively expensive in time and programming. According to the invention, therefore, the image values, after being read out serially, are converted by a shift register (5) into parallel output signals, before they are passed to a reference table device (6) to provide the desired output signal, which represents the memory content. The invention can be used in programmed control engineering, particularly for numerical control. <IMAGE>

Abstract: Phenylpyrimidinyl trans-cyclohexanecarboxylates of the formula 
<IMAGE>
 form, in addition to a relatively broad nematic phase, a smectic C phase if R<1> denotes an alkyl radical having 10 to 16 carbon atoms, in particular 11 to 16 carbon atoms, or an alkyloxy radical having 8 to 14 carbon atoms and R<2> denotes an alkyl radical having 2 to 9 carbon atoms. Accordingly, they are suitable in particular as components of liquid-crystalline mixtures having a smectic C phase, since they induce a relatively broad nematic phase or widen a narrow nematic phase present and enlarge the temperature range of the smectic C phase towards low, but in particular towards high temperatures.
Patent DE-3739499-A1 (DE)
Inventor: ACKERET PETER
IPC: G03B23/02
Filed: 1987-11-21
Abstract: A sheet changer which cyclically changes the distribution of a pile of sheets comprises a housing and a drawer which can be slid out of the housing. The pile of sheets is compressed by a spring arrangement against a window arranged in the housing. When the drawer moves, the pressure causes excessive friction, which is reduced by friction-reducing elements arranged between the drawer and the housing or the compression arrangement at the points on which the force of the spring is exerted.

Title: Device for trimming the longitudinal edges of running rolled band
Inventor: FRITZ MANFRED
IPC: B23D35/00
Filed: 1987-12-05
Abstract: A trimming installation 1 is equipped with devices for trimming the longitudinal edges of running rolled band 2, in which a rotating trimming cutter 14a or 14b and a rotating scrap or edge strip part cutter 15a and 15b are combined in the running direction 6 of the rolled band 2 to form a compact structural unit 16a and 16b. Two identically constructed compact structural units 16a and 16b are in this case mounted on a common support 13, angularly offset in relation to one another about a predetermined axis 11 directed perpendicularly to the run-through plane of the rolled band 2. This support 13 can in this case be moved about the axis 11 relative to the run-through region of the rolled band 2 into two different rotary positions, the angular spacing from one another of which corresponds to the angular spacing between the two compact structural units 16a and 16b. In this manner, it is possible to minimise the standstill times of the trimming installation 1 because the knife heads of the trimming cutters 14a and 14b and of the scrap or edge strip part cutters 15a and 15b can be exchanged outside the run-through region of the rolled band 2 during operation of the trimming installation 1.   <IMAGE>

Patent DE-3801541-A1 (DE)
Title: Indicator for monitoring the temperature of chilled products
Inventor: HOLZER WALTER DR
IPC: G01K13/10
Filed: 1988-01-20
Abstract: For monitoring the temperature of chilled products, which are stored in thermally insulating packages, an indicator is proposed, which has a temperature measuring probe which is arranged in the vicinity of the chilled product inside the package and has an indicator which can be read from outside. Electronic temperature monitoring is proposed of the type in which the temperature measuring probe is connected to a temperature monitor having switching means, which switches on the electronic display of the indicator only when the monitoring temperature is reached. In this way, battery power is saved, since the indicator is activated only close to the monitoring temperature.

Patent DE-3812720-A1 (DE)
Title: Thread for self-bracing screw-connection
IPC: E04C5/16
Filed: 1988-04-16
Abstract: In the case of a screw-connection - e.g. a socket connection of reinforcing bars - frictional locking of the connection is achieved by bracing the thread turns of the two threaded parts which are to be connected (checking). Since the turn height s (14) of one of the two interengaging threads (2, 11) changes in the end region from thread turn to thread turn by a small amount  DELTA  s, bracing of the two threads, i.e. frictional locking, is automatically achieved upon tightening of the screw-connection. <IMAGE>
