Patent DE-19823721-A1 (DE)
Title: Vehicle steering system
Inventor: KOJO TAKAHIRO
IPC: B62D6/00
Filed: 1998-05-27
Abstract: The vehicle steering system (2) is arranged with a step-up ratio alteration unit (14) positioned along a steering transmission system, which connects a steering wheel (10) and a wheel (24). The step-up speed ratio changing unit has a reduction mechanism, and a motor with control unit (28) which varies the rpm of the motor based on the vehicle condition. A housing for the motor, and a driven connection of the reduction mechanism, are both connected with the steering transmission system. The reduction mechanism has a reduction gear ratio which is sufficient for the lowering of a phase shift amount between a steering angle of the steering wheel and a rotation angle of the wheel, in relation to a force. The force reacts to the rotated steering wheel which is applied on the steering transmission system, so that it does not exceed a predetermined value.

A parallel port for connecting peripherals to a computer is independently claimed.
Patent DE-19825554-A1 (DE)
Title: Heating system, e.g. radiator coaxial pipework used as bent shaft
Inventor: HEWER ROLF A
IPC: F24D3/10
Filed: 1998-06-08
Abstract: The heating system has an inner feed pipe (11) projecting downwards from the housing (10) and having a hose mounting (18-20) below and a pipe sealing and fixing mount at the top end of the shaft (12). The thickness of the hollow shaft tapers conically inwards and steadily towards the mounting in the pipe, and the transitions between vertical and bent shaft parts are harmoniously rounded and curved. The axial interval between the shaft and radiator screw fitting is itself internally threaded and has an inside sealing cone (15) and corresponds to standard valve intervals. The outer pipe connection (14a,15a) faces the radiator or distributor connection (14,15) at right angles. The supply is brought in by a single externally visible line despite the use of a two-pipe system.
Patent DE-19830189-A1 (DE)
Title: Method of improving tilt stability of motor vehicle
Inventor: FENNEL HELMUT
IPC: B60T8/17
Filed: 1998-07-06
Abstract: The method involves reducing tilting if a parameter which correlates with vehicle (1) transverse acceleration exceeds a first threshold value. When the vehicle starts a journey, the threshold value is at a lowest value at which the danger of tilting occurs for permitted vehicle loading. The correlating parameter is at a point approximately corresponding to the unladen centre of gravity (G) and is a function of the transverse acceleration and its time derivative

Patent DE-19837409-A1 (DE)
Title: Carrier recovery in phase shift keying (PSK) homodyne receiver which receives PSK modulated optical signals from transmitter
Inventor: RAPP CHRISTOPH
IPC: H04L27/00
Filed: 1998-08-18
Abstract: In the receiver a local oscillation is generated and mixed with the received optical signal, to form a detection signal located in the base band. The oscillation is phase synchronized with the carrier signal of the received optical signal, using a phase error signal. The phase error signal is obtained from a specified asymmetry of the signal course of the detection signal. For this purpose scanning values, symmetrical about the mean time of scanning time point, are obtained from the detection signal, or by signal processing of previous signals. Then they are linked with the determined data or their derivatives or derived signals.

Patent DE-19908776-A1 (DE)
IPC: C04B11/26
Filed: 1999-02-19
Abstract: The invention relates to a method and an arrangement for producing alpha -calcium sulphate hemihydrate using the gypsum suspension produced during the wet flue gas desulphurization process of a fossil-fired thermal power station. The aim of the invention is to carry out a continuous process of converting and further processing gypsum to produce highly pure end products which is directly linked to the flue gas desulphurization process of a coal-fired power station. To this end, a partial flow is removed from the gypsum suspension taken from the flue gas desulphurization process (1) before dehydration and the solid parts are separated into dihydrate and unwanted constituents by one or more hydrocyclones (5). The thus purified suspension is heated, then mixed with a dispersion of crystallizers and nucleators (11), guided via the outer pipe (13) of a longitudinal, upright double-pipe heat exchanger (14) and after being heated again, is released to an optionally coil-shaped reactor (19) which is located underneath which has mixing screws, using the hydrostatic pressure. The suspension is then delivered to the inner pipe (21) of the double-pipe heat exchanger (14). The resulting alpha -calcium sulphate hemihydrate suspension in this inner pipe (21) is caused to rise to the exit level (22) and then dehydrated, the resulting powder then being dried and screened or ground. The invention also relates to an arrangement for producing  alpha -calcium sulphate-hemihydrate using the gypsum suspension produced in the wet flue gas desulphurization plant of a fossil-fired thermal power station.
