Title: Ammunition safety device permitting in flight arming - is triggered by the rotational acceleration of the body about its own spin axis.
Inventor: KRATZ BERNHARD
IPC: F42C15/22
Filed: 1992-09-12
Abstract: A safety device (10) for various types of ammunition, where the ammunition has a rotationally mounted target detector. The safety device (10) has a spray drive member (24) mounted to set off a detonator (38). The detonator (38) is moved by the spin of the ammunition, from a position radially outwards from the spin axis inward, hence changing from the safe to the armed position. The drive member (24), is coupled with a cocking slide (14) and a detonator slide (16) in order to produce a certain rotational acceleration or delay. The arming of the ammunition is achieved on attainment of a certain rotational time delay. This causes the cocking slide to move into forward armed positions. USE/ADVANTAGE - The design is particularly useful for air-dropped mines. The safety device can be installed in munitions without altering their outer dimensions. As the ammunition is armed by rotational acceleration and not by firing acceleration, it is possible to test the safety device while the munition is in flight.

Title: Method for indicating an operating liquid supply of motor vehicles
Inventor: ROEPFL NIKOLAUS
IPC: G01F23/00
Filed: 1993-03-24
Abstract: In a method for indicating an operating liquid supply of motor vehicles, in which a level transmitter supplies a raw measured value and a damping device connected downstream supplies therefrom a measured value cleaned of short-term fluctuations, and in which the cleaned measured value is indicated, the last indicated measured value is stored and indicated further in the event of a standstill of the motor vehicle. The raw measured value is stored as reference value, after a quietening time, and subsequent changes of the raw measured value are only taken into account if they exceed a predetermined measure of change. The indicated measured value is then corrected by the difference between the raw measured value and the reference value.

Title: Sewage nitrogen and phosphorus removal - separates nitrogen in a main flow and strips out the phosphor in a side flow
Inventor: BAUER UWE DR
IPC: C02F3/30
Filed: 1993-09-14
Abstract: To apply a continuous biochemical removal action on nitrogen and phosphorus from sewage, it is passed directly into a denitrification stage and the nitrogen is removed in a main stream through successive stages for denitrification, nitrification and sepn. The phosphorus is sepd. into a side stream where the activated sludge sepd. at the first stage is used for phosphate stripping after passing through an anaerobic stage in a second solids sepn. The sepd. sludge is returned as a sludge generally free of phosphate to the denitrification, while the phosphate-enriched water portion is passed to phosphate pptn. followed by sepn. of an assessable phosphate sludge. The activated sludge concn. is more than 4.5 kg/m3 in the denitrification, nitrification and phosphate stripping stages. The oxygen supply during nitrification is at a raised pressure of at least 1 bar. During phosphate stripping, a fatty acid material is added if there if a reduced fatty acid content. USE/ADVANTAGE - The method is for the continuous sepn. of nitrogen and phosphorus from sewage. The system does not require a number of large vol. vessels, and gives recovery of useful matter.

Title: Series transmission system for transmitting data between two stations
Inventor: HOFSAESS MICHAEL DIPL ING
IPC: G01R31/02
Filed: 1994-02-08
Abstract: The transmission system includes an evaluation circuit having logic gates which receive the output signals of two comparators (16,17). A resistance network (R5,R7,R6,R4) is connected in parallel to the comparators and between two driver circuits (T2,T3) and with respective bus-conductors (S+,S-). The reference potentials are so selected on one side and the resistance networks so designed on the other that, in fault free operation, both comparators give a switching signal depending on the transmitted bit conditions. With a short circuit of one of the conductors of the two wire lead however, against any voltage potential or with a short circuit of the conductors together, one of the comparators gives a switching signal. The other comparator persists in one of its two switching positions.

Title: Control of vehicle catalyser IC engine output
Inventor: HUBER WERNER DIPL PHYS DR
IPC: F02D41/04
Filed: 1994-02-15
Abstract: A car engine control unit uses an electrically operated throttle flap, and its rate of angle change is limited by engine operating parameters, when conditions leading to increased toxic emissions are expected. Such conditions are when the engine is cold or when the surrounding air is cold. The speed limit is a function of engine temperature, the intake air temperature and the elapsed time since the engine was started. The limit is lower when the gas pedal is depressed (i.e. acceleration) than when it is raised (deceleration).
