Inventor: SCHULENBERG THOMAS DR ING
IPC: F02C3/32
Filed: 1996-09-26
Abstract: The invention concerns a method of mixing a first fluid flow (17) with a second fluid flow (5) and a mixing device comprising at least one outlet diffusor (1) for a compressor (2) which compresses the first fluid flow (17). The first fluid flow (17) flows through the outlet diffusor (1) which has a feed line (3) for a second fluid flow (5) for flowing into the outlet diffusor (1). In a further configuration, the compressor (2) comprises a corresponding feed line (3). A preferred area of application of the invention is a stationary gas turbine plant in which waste heat is recovered. The invention in particular enables a closed outer wall (9) of the combustion chamber (7) to be cooled, such that the flue gases can be prevented from mixing with cooling air in the combustion chamber (7).

Patent DE-19703482-A1 (DE)
Inventor: STRECKER ERNST PETER PROF DR M
IPC: A61F2/86
Filed: 1997-01-31
Abstract: A known method for treating pathological body vessels is the implantation of stents (1) as an extended filament (2), by means of a catheter (22), which springs into a given form only once at the implantation site, as a result of its thermo-memory property or its elasticity. The invention relates to a new kind of stent (1), created in order to improve the flexibility and stability of the stent. This is achieved in that the stent filament or stent filaments (2, 2') are present in the form of at least two opposed spirals (3, 3'). The filament (2) consists of a material with high elasticity or with thermo-memory properties. The stent (1) can be covered with a structure made of pieces of fabric and/or fibres, and serves in this way as a stent graft. The new stent demonstrates high stability and flexibility. The stent can be introduced into a body vessel by means of a lumen, which essentially corresponds to the outside diameter of the filaments (2, 2') forming the stent (1), by means of catheter (22), and expands in the point of destination to a large-lumen tube-shaped implant.

Patent DE-19708252-A1 (DE)
Title: Piston for internal combustion engine
Inventor: WATANABE HIROAKI
IPC: F02F3/02
Filed: 1997-02-28
Abstract: The piston has an upper profile (3) cut with the piston ring grooves (5-7) and a lower skirt profile (4) to support the gudgeon pin mounting. The mounting is offset from the centre of the piston by an amount which counteracts the lateral stresses on the piston during the combustion cycle. The piston profile has a predetermined degree of taper, as well as the offset gudgeon pin, to further balance the lateral stresses during the combustion cycle. The gudgeon pin mounting includes flats for the pin position. A profiled slot (9) at the bottom of the piston ring profile provides a lubricating connection between the inside of the piston and the cylinder bore.

Patent DE-19729323-A1 (DE)
Inventor: KOCH RAINHARDT DIPL BIOL DR
IPC: C08B1/06
Filed: 1997-07-09
Abstract: According to the invention, samples of highly crystalline (>80 %) technical cellulose with a degree of polymerisation of approximately 1500 were enzymatically pre-treated with commercial endoglucansases under various conditions before being chemically converted to substituted cellulose derivatives. Said enzymatically pre-treated cellulose samples showed a significantly (up to 222 %) higher degree of substitution compared with control samples which had been pre-treated with buffer without enzymes. The increase in substitution during the chemical reaction was observed in the presence of various quantities of alkali, but decreased with reduced quantities of alkali. It was possible to significantly reduce the quantity of alkali required (by 60 %) and still obtain the same degree of substitution by using the cellulose samples which had been pre-treated with endoglucanase compared with the cellulose samples which had been pre-treated with buffer only. It was also possible to further increase the substitution of the enzymatically pre-treated cellulose samples by reducing the proportion of water in the reaction mixture used in the chemical reaction.

Patent DE-19732122-A1 (DE)
Title: Data transmission method
Inventor: FRANZ VOLKER DIPL ING
IPC: H04L12/52
Filed: 1997-07-25
Abstract: The method includes the steps of submitting data by a data source in bits, which are summed up in blocks, encoding the blocks in a coding arrangement, shuffling the coded data blocks with each other in an interleaver to form data bursts which contain the data of at least two blocks, and sending the data bursts over a transmission channel. The transmitted data blocks are received and corrected by a correction arrangement. The corrected blocks are subjected to a de-interleaver, and are decoded in a decoder. The decoded data blocks are led back at least once over an interleaver to the correction arrangement, whereby the information of a data block is used as a-priori information for this block and/or at least one timewise preceding data block and/or at least one timewise following data block. The data blocks submitted by the decoder are output after a predetermined amount of iterations to a data sink.

Filed: 1997-12-08
Abstract: The width of the air extraction duct rising above the rotating plate (6) and around the loading chute (11) is reduced to an annulus (s), before increasing asymmetrically (S), so that the variation in the local velocity energy of the air around the duct is minimized. The separator has a cylindrical casing (5) with a central loading chute (11) through which the material to be separated falls onto a rotating plate (6), which flings the material radially outward into a rising air stream. Lighter particles are carried upwards with the air stream, through an annular extraction duct around the chute, and out through a radial near-horizontal discharge funnel (7). Heavier particles fall and leave through the bottom of the separator.

Title: Semiconductor dynamic memory device with test configuration
Inventor: TSUKAMOTO YUKIHIRO
IPC: G11C11/406
Filed: 1998-03-04
Abstract: The semiconductor memory device has a number of memory locations (MC), which are arranged in a matrix of rows and columns, and has a special operating mode. When this mode is initiated, a test oscillation circuit (6i) is activated. The test oscillation circuit operates with a cycle, which is shorter than that of a refresh oscillator circuit (6c) that specifies a self refresh cycle corresponding to an external row address clock signal. The internal row address clock signal is supplied to row control circuits (6k) through a selector (6j). An internal row address clock signal can be activated with a cycle which is shorter than the cycle of the external row address clock signal, to perform row selection. One row is selected with a cycle which is shorter than the transition cycle of an external signal.
