Patent DE-19904108-A1 (DE)
Title: Data transmission method for radio communication system
Inventor: BAHRENBURG STEFAN
IPC: H04J13/00
Filed: 1999-02-02
Abstract: The method involves connecting a base station to several mobile stations via a radio interface. Transmitting stations can either send radio blocks which are short and orthogonal in time or one long radio block in a time slot. The radio blocks include midambles and data parts. A long radio block includes two midambles which are so positioned that the two midambles are received after transmission at the same time as midambles of short radio blocks in the same time slot.  Preferably, the transmitting stations are the mobile stations and the receiving stations are the base stations. The radio blocks can be access radio blocks for a resource request or an acknowledgement message.

Title: Process for reducing the inorganics content in fossil fuels, especially brown coal, comprises subjecting the coal to acid gas and mechanically/thermally dewatering
Inventor: STRAUSS KARL
IPC: C10L9/02
Filed: 1999-02-06
Abstract: Process for reducing the inorganics content in fossil fuels, especially brown coal, comprises subjecting the coal to acid gas, e.g. CO2, where the gas pressure is selected so that the coal absorbs an amount of gas required to produce the desired demineralization effect and reacts with it, and mechanically/thermally dewatering the conditioned coal so that the inorganics converted into soluble form are removed from the coal.  An Independent claim is also included for an apparatus for carrying out the reducing process comprising a sealed gas-tight vessel held under a specified pressure.

Patent DE-19905826-A1 (DE)
Title: Integrated stereophonic sound amplifier circuit
Inventor: JOHNSON NICK M
IPC: H03F3/68
Filed: 1999-02-12
Abstract: The amplifier amplifies strongly correlated signals (111R, 111L) for a left and a right channel, and includes a first (114R) and a second amplifier circuit (114L) integrated in a semiconductor substrate. A phase converter circuit (120) inverts the phase of one of the signals before its amplification, so that the respectively other signal is amplified with a small or without a signal phase reversal.  The amplifier amplifies strongly correlated signals (111R, 111L) for a left and a right channel, and includes a first (114R) and a second amplifier circuit (114L) integrated in a semiconductor substrate. A phase converter circuit (120) inverts the phase of one of the signals before its amplification, so that the respectively other signal is amplified with a small or without a signal phase reversal. This amplified sound signal is supplied either to the non-inverting or inverting connection of a corresponding loudspeaker.   The other inverted and amplified sound signal is supplied subsequently at the opposite connection, i.e. the inverting and/or non-inverting connection, of the corresponding loudspeaker. Simultaneous power supply requirements of both channels are thereby reduced considerably, if strongly correlated signals are amplified for the left and/or the right channel.

Title: Concentration of nitric acid or separation of other mixtures forming azeotrope by extractive distillation uses process heat for heating feed and recycled, very concentrated extractant
Inventor: DICHTL GOTTFRIED
IPC: C01B21/44
Filed: 1999-05-05
Abstract: In 75-99.9% nitric acid (I) production from dilute (impure) (I) by rectifying 45-70% (I), using circulating extractant (II), the (I) feed (IA) is heated to a boiling liquid, vapor-liquid mixture or separate vapor and liquid with (part) of the heat content of all process streams;  >=  50% of (IA) is pre-mixed with 0.1-60% (concentrated) (I); indirect heating is used for rectification; and a very concentrated (II) feed is used to minimize the amount circulating and maximize dilution.  Production of 75-99.9% nitric acid (I) from dilute, optionally impure (I), involves rectification of 45-70% (I) under pressure, at atmospheric pressure and/or in vacuo in contact with a liquid extractant (II) to prevent the formation of a HNO3-water azeotrope, condensing the concentrated (I) vapor and recovering concentrated (I); and also reconcentrating (II) and recycling it to extractive rectification. The novel features are that:  (i) the heat content of the process streams in the entire process is used partly or largely; (ii) the (I) to be concentrated is fed to extractive distillation as boiling liquid, vapor-liquid mixture or separate vapor and liquid, using this heat; (iii)  >= 50% of the amount to be rectified is mixed with 0.1-60% HNO3, preferably concentrated (I), before rectification; (iv) the energy required for rectification is supplied (mainly) by indirect heating; and  (v) the (II) fed to rectification in as concentrated a form as possible, to minimize the amount of circulating extractant and, at the same, maximize the dilution of (II) discharged from rectification. Independent claims are also included for:  (a) the plant used in this process; (b) a process for producing a concentrated product fraction from a liquid mixture forming azeotrope(s) by extractive rectification in the same way, especially for separating highly concentrated volatile products from dilute aqueous mixtures or for separating mixtures of organic compounds.

Title: Wheel with bending-resistant spokes, for bicycles etc. has spokes formed from sheet metal with profiling, in a one-piece star part, one for each side of a wheel
Inventor: FISCHER HENNIG
IPC: B60B1/10
Filed: 1999-11-20
Abstract: The wheel has a rim (10), a hub (20), and spokes (30) formed from sheet metal with profiling (31) of some type at one point. This permits all spokes to be fitted without tension, and any loads to be accommodated without bending or bulging. The spokes are not positioned in the central plane of the wheel, but are offset from the center within the hub, so that a form-stable triangle is formed, which can accommodate lateral forces. All spokes are formed in one-part star shape, one for each side of a wheel. Opposite spokes are connected to each other and to the rim via a connection part (40), and the rim can be replaced without the spokes needing to be disconnected.
