Patent DE-2845762-A1 (DE)
Inventor: HOLY ANTONIN DR
IPC: C07D473/34
Filed: 1978-10-20
Abstract: Improved antiviral medicines are those which contain as active component (S)- or (RS)-9-(2,3-dihydroxypropyl)adenine of the formula I <IMAGE> where appropriate combined with 9-( beta -D-arabinofuranosyl)adenine of the formula II <IMAGE> The compounds are effective medicines for viral diseases such as, for example, vaccinia, herpes simplex 1, herpes simplex 2, measles, vesicular stomatitis and the like. The advantages of these medicines include low toxicity of (S)- and (RS)-9-(2,3-dihydroxypropyl)adenine, their easy availability and high stability. Combination with 9-( beta -D-arabinofuranosyl)adenine reveals the synergistic effect of the two components. This results in a lowering of the dosage of the toxic and costly 9-( beta -D-arabinofuranosyl)adenine, with the same biological action being achieved, and its breakdown in the body is restricted.

Title: Artillery shell steered by gas jets - has electronic control operating control valves for nozzles in sides of shell
Inventor: TROMMSDORFF WOLF DR DIPL ING
IPC: F02K9/88
Filed: 1978-10-25
Abstract: The system is for increasing the accuracy of artillery shells (2). It involves controlled application of a force transverse to the line of flight of the shell. The force is applied by generation of an additional shock wave on the side of a shell flying through the air at supersonic velocity. The shock wave is generated by a stream of fluid or gas, discharged transversely from the shell through a convergent-divergent nozzle (10). There may be several nozzles arranged in a belt round the mid-section of the shell. Gas from a bottle (18) passes through valves (20) to the nozzles. There is an igniter (26) in front of each nozzle, connected to a control circuit (22) connected to the control valve. A main control circuit (24) is connected to each of the valve control circuits.
Patent DE-2847432-A1 (DE)
Title: Prevention of sudden rock movements in coal mining - by stress-releasing injection of aq. salt solns. e.g. of calcium chloride and nonionic wetting agent
Inventor: LEWER HANS
IPC: E21F5/18
Filed: 1978-11-02
Abstract: Sudden rock movements in coal mining are prevented by injecting the coal seams with aq. salt solns. through boreholes driven from outside the coal extraction area, from seams above or below that being worked or from independent mine workings. Pref. the soln. used contains 30-40 wt.% CaCl2 and/or MgCl2 and 0.2-0.5% non-ionic wetting agent. Stresses in the rock layers can be released without interfering with coal extraction. Coal pillars left to prevent subsidence can be treated. The good wetting action of the salt soln. used allows injection under relatively low pressure and prevents escape into adjacent rock formations or breaking up of the coal.

Title: Passenger compartment door sealing and sound attenuation testing - using compressed air directed at seal and acoustic sensor
Inventor: GEIB WILLI ING GRAD
IPC: G01M3/24
Filed: 1978-12-15
Abstract: A testing method determining the sealing and sound attenuation of seals between components is partic. applicable to elastic seals in vehicle passenger compartment doors. Acoustic source and sound level detectors are placed either side of the door or door seal. The m ethod enables the seal to be subjected to representative pressure conditions under text. The seal is subjected to a flow of pressurised gas at least in sections with the level sensor mounted on the outflow side of the seal. An overpressure is produced inside the passenger compartment by the gas flowing in fin the form of pulsed compressed air. The noise source may be formed by the noise of the air flowing out of the compressed air supply.

Title: Tunnel cutting machine with soil shifting tool - which fits on adjustable arm and has laser beam aligning target point on cutting face using reference to obtain correction signals
Inventor: ODENKIRCHEN HORST ING GRAD
IPC: E21D9/10
Filed: 1979-01-17
Abstract: The soil-shifting tool on a tunnel cutting machine has a mechanism for limiting the adjustment movement of the suport arm. The position of the arm is determined by a laser beam. The deflection angle of the support arm is determined and a related reference value worked out. Any deviation is corrected by the appropriate correction signals. The target point of the laser beam is aligned onto the face before each thrust and before or after inserting the shiffing tool. The angles are determined w.r.t. the horizontal and the vertical and converted into signals and compare with reference values. The differences are used for the correction of the control of the profile.

Title: Mfr. of nitrous oxide calibration gas sample - using source of nitrogen di:oxide a stream of which is catalytically reduced to nitrous oxide to produce mixt.
Inventor: LEUTHER HANS GUENTHER
IPC: G01N33/00
Filed: 1979-02-09
Abstract: A mixt. of NO and NO2 for calibrating an NO analyser is produced from a source of pure NO2. The sample of pure NO2 is fed to a permeation furnace and then into a catalytic reduction reactor. In this the NO2 is converted to NO. The required mixt. is obtd. by the amount of NO2 which bypasses the converter. In this way any concn. of NO can be obtd. Used for calibrating NO analysers. The storage of NO contg. gases is difficult because the compsn. varies with time and is also costly. NO2 is stable and the NO is then produced freshly when required.

Patent DE-2945338-A1 (DE)
Inventor: CZECH JOACHIM
IPC: B65D83/00
Filed: 1979-11-09
Abstract: A dispenser for pasty products has a cylindrical body with an open bottom and an outlet in its top. A piston that closes the bottom of the body, cooperating with it to define a chamber, is slidable upward in the body for expelling contents of the chamber out of the outlet. An actuator on the exterior of the body, movable in opposite directions, is manually movable to one limit of its motion and biased to the other limit. A rod connected with the actuator and movable lengthwise up and down in the body has a unidirectional driving connection with the piston that constrains the piston to move upward with it but allows it to move down relative to the piston. A check valve associated with the outlet opens to allow discharge of chamber contents but closes to block flow into the chamber, thus enabling atmospheric pressure to hold the piston against downward motion. Several advantageous unidirectional connections are disclosed.

Title: Vehicle measurement device test circuit - uses alternative signal source to isolate location of detected fault
Inventor: BUCHLEITNER KONRAD ING GRAD
IPC: G01P21/02
Filed: 1980-07-17
Abstract: The test circuit is applicable to devices which normally produce a series of pulses from a transducer and are installed in vehicles. It enables the location of the defect in either the measurement device or transducer quickly and at low cost. The pulse signal from a second device, e.g. the ignition system, is simultaneously fed to the measurement device under test. The device under test may be the tachometer (1) and the further device the revolution rate sensor (7). The second pulse signal may alternatively be generated by a three-phase generator. The sensor (3) may be isolated by a switch (4) which allows the second pulse signal to pass from an adapter circuit (5) to the test device (1).
