Title: Device on an extrusion system
IPC: B29C48/09
Filed: 1998-08-04
Granted: 2000-09-25
Abstract: In order to simulate the operating load for an extruder 1 during the emission of the extruded compound, for example via a changeover valve 3 to a purging line, a variable friction resistance is provided as an equivalent load. This comprises a variable-length L friction channel, for example with a constant annular cross section between a needle 4, 9, 11, 13, 15 which can be pushed in, and a hole 8, 10, 12, 14, 15, 16. The insertion or adjustment of the friction coefficient is carried out via a controller 7. The operating pressure at the output of the extruder 1 is determined and stored, and the friction coefficient of the equivalent resistance is increased until the stored operating pressure is reached. <IMAGE>

Title: Device for suspending strip-shaped light shields on a ceiling
IPC: F21V11/04
Filed: 1988-06-10
Granted: 1990-01-25
Abstract: In a device for suspending strip-shaped light shields on a ceiling, the edge, facing the ceiling 15, of each light shield 1 is clamped between the lower limb 2 of an H- shaped profile 3. Fastened on an upwardly projecting fastening rod 5 are clamps 4 which embrace the profile 3. This fastening rod 5 is plugged into the limbs 7, 8 of an elastic holder 6 which is bent approximately in the shape of a U. A suspension rod 14 with the aid of which the device can be fastened to the ceiling 15 is plugged into the holder 6 in a fashion parallel to the fastening rod 5. The result of this arrangement is that this device can be used to align the light shields exactly and yet simply. <IMAGE>

Title: Control device for an electric switch for switching pumps such as submersible pumps and the like
IPC: G05D9/12
Filed: 1982-12-17
Granted: 1987-07-10
Abstract: A control device for an electric switch 14 for switching liquid pumps 11, in which, in a watertight housing, a solid or liquid weight which assumes opposite end positions depending on the height of the liquid level 21 is arranged as a flow 20 and can move on a guide path, in order not to need any power connection to the float housing 20 and therefore to act reliably without a current flow in the float housing 20, an optical fibre bundle 17 is lead through the float housing 20, its one end being opposite an optical transmitter 15 and its other end being connected to a stationary optical receiver 16. Here, the solid or liquid weight interrupts the transmission of light in the optical fibre bundle 17 depending on the position of the float housing 20, and therefore triggers a switching operation. <IMAGE>

Date Dec. 18, 1986.Process for recovering chemicals and energy from cellulose waste liquors preferably black kraft liquor obtained in a paper pulp sulphate process, comprising the following, three distinct and separate steps: In the first step the concentrated black liquor is gasified in a pressurized gasification reactor by so called flash-pyrolysis at 700 DEG  to 1300 DEG  C., normally 800 DEG -900 DEG  C., whereby an energy rich gas is produced, and in which the inorganic chemicals of the black liquor are contained in the form of molten suspended droplets, mainly comprising sodium carbonate and sodium sulphide. In the second step the gas from the gasification reactor is rapidly cooled through direct contact with water, and with green liquor, which is formed when the molten droplets and the hydrogen sulphide are dissolved in the quench liquid. The cooled gas subsequently passes through a scrubber. In the lower section of the scrubber the gas is washed with circulating green liquor, and in the upper section of the scrubber the gas is washed with sodium hydroxide (or carbonate) solution and water for complete removal of any remaining sulfur bearing components in the gas. In the third step the now sulfur and particulate-free gas is used as a fuel for generating steam and, if it should be economically justified, also for production of electric power.

A különféle kisvízfolyások árhullámzásának regisztrálása különösen a növekvő környezetvédelmi feladatok során kapott különös jelentőséget. Ezen kisvízfolyások árhullámzását általában a hirtelen lehulló csapadékvíz okozza, amely csapadékvíz a talajból különféle szerves, illetve szervetlen anyagokat mos ki, és így ezek a csapadékkal együtt a vízfolyásba kerülnek. Ezek pontos meghatározása igen fontos az ökológiai folyamatok megismerése és így a megfelelő környezetvédelem érdekében. Találmány feladata olyan mintavevő készülék kialakítása kisvízfolyások árhullámzásának regisztrálására, amelynek kialakítása egyszerű, de alkalmas az árhullám legalább két állapotának megmintázására.
