Abstract: The invention relates to a system for signalling and locating vehicles involved in accidents, stopped vehicles and vehicles with mechanical problems in daytime and night-time conditions as well as in adverse weather conditions. According to the invention, the occupants of the vehicle can raise the alarm without leaving the vehicle such as to avoid any physical risk. The invention comprises a case and a hinged cover housing an air container. One end of the air container is connected to a gaseous fluid outlet pipe and to a manual quick-opening non-return valve which is located in the mouth of an empty aerostatic inflatable fluorescent body. The aforementioned body is folded inside the case when not in use and is deployed in the event of a vehicle impact by means of a device comprising an inertia sensor which is activated by a deceleration force exceeding 3G and which is powered by a power source comprising batteries or accumulators belonging to the electric circuit of the vehicle or independent batteries.

Said drum/worm circulates in a conveyor pipe/worm trough (6/38) in a driven manner. Said pipe/worm is provided with a supply opening (11) directed towards the top and an outlet (10). The processing drum (3) or the conveyor worm (9) and the extruder worm (8) are aligned with the longitudinal axes (17, 20) and the processing drum/conveyor worm (3, 9) is detachably and mechanically connected to the extruder worm (8) and both are driven by a transmission (31) and a driving motor (34).

Abstract: This invention relates to electron guns, each comprising of an indirectly heated cathode, a gate electrode and an anode, for generating electron beams of various shapes and power that are preferably used to machine workpieces. Thus cathodes can be used with various geometric designs. Thus cathodes of the most varied geometrical shapes can be used. Along with band cathodes and band cathodes with bodies attached to them, massive cathodes such as bolt-type cathodes can also be applied. Using massive bodies results in a longer service life of the cathode as compared to band cathodes. Another benefit is that the service life of the heat source for the cathode is identical to the service life of the laser used. It is particularly advantageous to place the laser outside the housing, which ensures a very long service life of this source of heat. At the same time, the solution according to the invention is distinguished by an indirect temperature measurement of the cathode.

Abstract: The invention relates to a device for the automatic release of a flushing process after use of a urinal or similar sanitary appliance. The invention is characterized in that at least one sensor is placed in the trap. When the level of the liquid in the trap changes, the sensor generates a switching impulse which controls a water electrovalve.

Abstract: An apparatus for use on a vessel and for gaining access to a fixed structure such as a marine platform. As shown a supply vessel (1) has located on the deck (2) a mounting (3) which is connected by a gimbal arrangement (30) to a support arm (4) carrying a boom assembly (5) with a capsule (6) for personnel. The arm (4), boom (5) and capsule (6) are controlled in position by hydraulic means (9, 31, 33, 36, 40, 41, 52) to be manoeuvred into a required position to transfer personnel to the platform or decking (7) for example. In order to stabilise the position of the capsule (6) relative to the platform (7) the hydraulic means (9, 31, 33, 36, 40, 41, 52) is dynamically controlled to compensate for movement of the vessel (1) such that the capsule (6) will remain substantially in the selected spatial position relative to the platform (7). The capsule (6) may include a control system which enables an operator to statically position the capsule (6) through control of the overall systems.

Abstract: An apparatus for cleaning a fluid in the form of steam from a circuit in which a given flow of water vapour is generated and led to a separator (1) and thence to a cooler or a condenser or it is discharged into the atmosphere, said separator (1) comprising a closed volume (2), a steam inlet duct (4) and a steam outlet duct (5) opposite one another on said closed volume (2) incorporating a tabular element (3) lying below the vertical and sloping downward in relation to said steam inlet (4), forming a channel (6) at the bottom with a discharge pipe (7) which moves the liquefied substances and particles adhered to said tabular element (3) to the bottom of said closed volume (2) from where they are removed through drains (8).

Abstract: The invention relates to a device for identifying gaseous compounds, comprising a sensor array (1) having, for instance, ten gas sensors (2) in the form of semiconductor gas sensors. Said sensor array (1) has a supply line (3) with an inlet (4) and an outlet (5). A switchable three-way valve (6) is located in the supply line (3), to which a selective collector unit (7) is attached. Said collector unit (7) comprises a special adsorber (8), a heater (9) and a separate feed pump (10) with a flow sensor (11). A secondary line (12), in which a dilution unit (13) is arranged, discharges into the feed line (3) between the three-way valve (6) and the sensor array (1). A feeding and control unit (16) also having a feed pump (17) with a flow sensor (18) is located in the area of the outlet (5) of the sensor array (1). An electrical line (19) leading to an evaluation computer (20) branches off from the sensor array (1).

Abstract: The outflowing casting metal on the path to solidification is no longer subjected to reoxidation and degassing of the casting metal in case of unkilled melts and can immediately be performed ahead of the casting process in a method for continuous casting of metal strands from high-melting metals with cross-sections close to the end dimensions according to the principle of the communicating pipes, and further a temperature and analysis correction can be performed. These conditions are fulfilled by pressing the casting metal from a higher disposed storage container through the communicating channel pipe (8) into a pressure vessel (13) with a gas dome (20), where the casting metal is further transported through an immersion pipe (14), which immerses into the casting metal through the gas dome, into a substantially vertically oscillating independent continuous casting die (15) and where the casting strand formed is deflected in an arc from the vertical direction into the horizontal direction and is withdrawn.

The suction chamber connects coaxially to the steam chest and has a coaxial suction chamber cavity with an inlet opening. The diffuser is coaxial with the steam chest and the suction chamber and has an elongate coaxial passage for exhausting the suction chamber cavity. The nozzle unit interconnects the steam chest cavity and the suction chamber cavity is coaxial therewith.

Abstract: A method is provided for production of steel in a basic converter employing liquid converter slag obtained as a final slag in the previous run, where roughly half of the slag from the preceding charge is left in the converter. The basicity of the initial slag is thus considerably increased and the slag is maintained preferably over the total converting process, but at least during the critical initial stage at the saturation level with respect to magnesium oxide and dicalcium orthosilicate. At a certain level of silicon content in the pig iron the process is operated with a predetermined slag amount for each ton of steel at the end of the blowing by adding to the initial melt or respectively at the beginning of blowing a certain amount of magnesium oxide expending on the silicon content of the pig iron together with the flux charge materials. This process considerably improves the lifetime of the converter lining.
