Patent DE-19758486-A1 (DE)
Title: Biological purification of waste water using nitrification and denitrification reactors
Inventor: DICKGREBER MICHAEL DR
IPC: C02F3/30
Filed: 1997-06-06
Abstract: In a process and assembly for the biological removal of nitrogen from waste water (4), the water is introduced to a reactor which has two zones containing a substrate material, in which the water is fed through an anoxic part of the reaction zone (2). In this zone suspended solids are retained, the chemical oxygen demand and biological oxygen demand are reduced, and nitrogen in the form of nitrate is reduced to elementary nitrogen. Water thus treated is then surrendered to the second reactor zone (1) in which it is aerated (8a) to produce an oxygen-rich zone in which the nitrogen compounds are oxidised to nitrate.  The novelty is that: (a) the reaction zones (1, 2) are separated from each other by a nozzle plate; (b) the reaction zones contain different types of support (for bacteria) having different grain size and density; and (c) the lower part of the anoxic reactor zone (2) has support material of fine grain and low density, while the aerobic zone above (1) has a support material of low density and coarse grain.  Preferably the support material is polystyrene.

Patent DE-19806719-A1 (DE)
Inventor: SPIES KLAUS PROF DR ING
IPC: F16G13/12
Filed: 1998-02-18
Abstract: The invention relates to a driving chain especially for use in mining machines, such as chain conveyors or chain-driven extraction machines in particular, comprising chain links (1,2) which are suspended flexibly in each other. Said power transfer chain links (1), which transfer the drive power or drive torque to said drive chain are provided with exterior faces running in a straight line across the chain axle and thicker noses on both sides of their middle swivel sector (8), said middle swivel sector (8) forming the chain joining point. According to the invention, the interior openings (4) of said power transfer chain links (1) are provided with bearing and support surfaces (16) on both sides of the swivel sector (8) of said power transfer chain links, for the suspended eyelet-type connecting elements (2), said bearing and support surfaces (16) running across the longitudinal middle axis (L). The width (b) of the noses of said connecting elements (2) measures more than the opening width of said swivel sectors (8) at the interior opening (4) of said power transfer chain links (1). This results in good power transfer ratios for the chain links of the drive chain, the strength of the power transfer chain links of said drive chain being optimized by material accumulation in the outer areas of the chain nose.

Title: Controlling link related security functions
Inventor: BOLZ GERT
IPC: H04Q7/38
Filed: 1998-03-19
Abstract: The method involves conducting a subscriber authentication between the mobile station (MS) and the communications network (PLMN) to check access authorisation as soon as a link is initiated by the mobile station. A key request for retaining the secrecy of the information on the interface (AIF) is sent to the mobile station from the communications network.  The key request is received by the mobile station and evaluated with an identifier showing whether the communications network requires a connection to the radio interface with encoded information or with unencoded information. The mobile station can be switched over under subscriber control to an operating mode in which the connection is broken if the received identifier permits a connection with unencoded information.

The light (5) is absorbed strongly, with heat emitted weakly, or the absorbent layer(s) give(s) strong heat emissions to the other opposing layers. The heating action of the absorbent layer(s) is controlled by the strength of the light striking it/them, and the light absorption is at least partially dependent on temperature. The light transmission through the light permeable layers is at least partially dependent on the light strength. The layered structure (4) is at least partially permeable to steam. An Independent claim is included for a layer structure (4) with at least one layer which is permeable to light, and at least one layer which is at least partially permeable to light and at least partially a thermal insulation. The layer structure (4) has at least one layer which absorbs light (5) at least partially. The layer with partial light permeability and partial thermal insulation is between the light permeable and light absorbent layers. Preferred Features: At least one light permeable and insulation layer and one side of the light permeable layer partially absorbs light in the infrared range of 5-30 microns and/or at least partially reflects it. At least one side of the light absorbent layer can carry a selective coating with a high absorbency of light (5) and at least partially low emission in the infrared range of 5-30 microns. The layer absorbs light on one side and reflects light on the other side. The absorbent layer can be structured to give high heat emissions to the other layers in the layered assembly. The layer structure (4) is at least partially of a steam permeable material and/or is an assembly of materials which are permeable to steam and is at least wholly or partially waterproof and windproof. The layer structure (4) is part of a garment, which can be worn with both sides, or part of a blanket.

Title: Throttle valve device for automobiles
Inventor: SATO HISAAKI
IPC: F02D9/10
Filed: 1998-12-03
Abstract: The throttle valve device has a throttle body with a part of an induction channel, a throttle valve (3) that is fixed rigidly to the valve shaft and is located so that it can rotate in the part of the induction channel, and a drive apparatus (4), located on the throttle body, drives the throttle valve via the valve shaft. A reduction gear device (5), by which the drive device and the valve shaft are mechanically joined, transmits a drive force of the drive apparatus to the valve shaft in a way to attain a speed reduction for a rotary movement of the drive apparatus which is to be transmitted to the valve shaft. A cam lever (11), encircled by the reduction gear device, has a cam surface (12) which allows the throttle valve to be turned from a fully closed to a fully open position. The cam surface has a bent section, so the throttle valve adopts a partly open position between the fully open and fully closed positions. A cam follower (14), rotatably located on the throttle body, is in contact with the cam surface. A pretension device (18) constantly pretensions the cam follower upon the cam surface of the cam lever, being in a position to press the follower onto the curved section to hold the throttle valve in the partially open position when the drive force of the drive device is removed.
