Abstract: The subject matter of the invention is the new 2-azido-3-benzyloxy-propionic acid benzyl ester which is a valuable intermediate product for the production of D,L-serine or derivatives of D,L-serine. The new compound is produced by reacting 2-chloroacrylonitrile with twice the molar amount of benzyl alcohol to form 3-benzyloxy-2-chloropropionic acid imino benzyl ester, saponifying this with acid to form 3-benzyloxy-2-chloropropionic acid benzyl ester, and finally exchanging the chlorine atom by means of an alkali metal azide in the presence of a phase transfer catalyst for an azido group.

Abstract: PCT No. PCT/EP88/01048 Sec. 371 Date Aug. 9, 1989 Sec. 102(e) Date Aug. 9, 1989 PCT Filed Nov. 18, 1988 PCT Pub. No. WO89/05438 PCT Pub. Date Jun. 15, 1989.A goniometric device for measuring an angle such as the angle of rotation of the steering wheel in a motor vehicle is useful for providing a backlash-free reduction ratio of the angular movement to be measured. For this purpose an elastic torque rod is used to one end of which the angular movement is applied and the other end of which is rigidly fixed. The angular movement of a tap is taken off at a tap location between the two ends. The reduction ratio depends on the ratio between the two distances from the tap to both ends of the torque rod.

Filed: 1993-02-26
Granted: 1994-10-27
Abstract: Known step-up/step-down voltage converters have problems when starting up after switching on, which arise in that the full value of an input voltage (Uin) is applied as soon as it is switched on, whereas no output voltage (Uout) is yet present. Switching logic (UL) recognises the lack of output voltage (Uout) and switches in step-up voltage conversion operation, although step-down voltage conversion operation is correct in this case. In order to eliminate this problem, a decision criterion for forced switching on of step-down voltage conversion operation is introduced. According to the decision criterion, step-down voltage conversion operation is switched on if the input voltage (Uin) is greater than the output voltage (Uout). <IMAGE>

Abstract: An apparatus for drying bulk material is proposed, said apparatus comprising at least one bulk container. This bulk container 10 is connected, within a closed air circulation system, to an air-drying facility 11 and a heating facility 15. The dry, heated air is passed through the bulk material 12 by means of a fan in order to draw moisture from the bulk material. The outgoing air charged with moisture is extracted from the bulk container 10, then dried again, heated by means of the heating facility 15, and then returned once more to the bulk container. An attachment piece 16 for the admission of the dry air is provided in the upper area of the bulk container 10. This attachment piece opens into a pipe 17 which is arranged centrally in the container and whose lower end is equipped with an air diffuser 18. The pipe 17 extends through the inside of the bulk container 10 and is designed with heat insulation properties. <IMAGE>

Title: Device to create inert atmos. in containment vessel of nuclear reactor
Inventor: ECKARDT BERND DIPL ING
IPC: G21C9/06
Filed: 1994-06-21
Granted: 1995-08-24
Abstract: A device to create an inert inner atmosphere for a nuclear reactor containment vessel (1) has a large number of parallel connected fluid outlets (9) for the inert gas. The flow velocity of the gases in the openings is at least 0.3 that of sound velocity in the same gases. Utilisation of all of the openings (9) for supply of inert gas ensures that after two hours the oxygen content in the container is less than 17% volume. At least one of the openings (9) is shaped as long tapered jet (22). At least one of the openings is a right angled funnel shaped jet (22) with a ratio between small and large sides of between 1 to 10 and 1 to 40.  The jets (22) have a range of more than half the largest dimension of the containment. A number of jets can be designed as venturi jets, in order to give a gas velocity greater than the gas sound velocity. A further use of the inert gas jets is to drive a suction jet to remove the gas already present in the containment. By use of a supersonic insert gas jet, it is possible to entrain five times the amount of inert gas from the container inner atmosphere.

Title: Injection system for hybrid rocket propulsion unit
Inventor: STINNESBECK THOMAS DR
IPC: F02K9/72
Filed: 1994-06-24
Granted: 1995-09-28
Abstract: In an injection system for a hybrid rocket propulsion unit, the liq. component is passed through small channels (2) in the fuel block (3) to the combustion face of an inner burner so that an optimal fuel/oxidiser mix ratio is obtd. at each point of the combustion surface. The channels extend radially from the combustion chamber periphery to its interior, repeatedly intersect the combusted gas flow direction at an angle or orthogonally and are in the form of either simple bores through the solid fuel or tubes e.g. of metal, the channel system disappearing during the combustion process. The channel arrangement provides the desired burn-off properties and geometry by local grouping, concn. bore changes or blind ends which are subsequently opened during fuel combustion. The channels are supplied with oxidiser in groups which can be regulated individually or in their entirety.
