Patent DE-4123258-A1 (DE)
Inventor: MOHN ULRICH
IPC: B01D53/50
Filed: 1991-07-13
Abstract: In a process for cleaning an exhaust gas containing sulphur dioxide and possibly other pollutants, the exhaust gas is freed of dust and washed in at least one stage with a calcium-containing washing liquid and the calcium sulphite formed is converted into calcium sulphate (gypsum) with the supply of air. Then the washing liquid containing gypsum is extraded and gypsum is separated from the extracted washing liquid. In order to produce gypsum containing no mercury, a chemical converting the mercury into a water-insoluble compound and/or an adsorber adsorbing the mercury is added to the exhaust gas before washing or to the washing liquid itself and the water-insoluble compound or the charged adsorber is discharged with the waste water during the separation of the gypsum from the washing liquid extracted.

Title: Throttle valve linkage for IC engine - allows control of unwanted relative movement by use of coupling pin and latch
Inventor: KETTENBERGER JOHANN
IPC: B60K28/16
Filed: 1991-08-03
Abstract: The actuation mechanism is for a throttle valve on a vehicle engine. A position lever (5,5'') actuated by the driver causes a positive fit actuation of a control lever (3) via a coupling spring (4). On the appearance of an undesired relative movement between the position lever and the control lever, the latter at least in the region of one of its end contacts is positively connected to the position lever by a coupling pin (8) and a latch (9). USE/ADVANTAGE - Mechanism which ensures a more precise control of throttle valve action in relation to engine behaviour.

Patent DE-4201157-A1 (DE)
Inventor: FUNCK THEODOR DR
IPC: G06F1/03
Filed: 1992-01-17
Abstract: A direct digital synthesiser (DDS) (1) or digitally operating function generator contains one or more channels (A, B, ...), each with a phase increment register, and is controlled by a computer installation (2) (e.g. a PC) via the transmission of information bits to the DDS (1) by the computer installation (2).

Title: Coin-op. gaming machine with rotating symbol wheels and win matrix display - illuminates display fields to indicate incremental cash wins, free plays or special plays depending on appearance of selected symbols
Inventor: SCHOENE SIEGFRIED
IPC: G07F17/32
Filed: 1992-01-18
Abstract: The gaming machine has a matrix display (8) with light-emitting elements in individual matrix fields.

Filed: 1992-03-17
Abstract: An electronically switched small-power motor operated with a d.c. voltage network has a plate-like stator (10) and a disk-like rotor (11) with axially magnetized magnetic poles. In order to reduce the speed of rotation in an optimal manner for each application at the operating point of the small-size motor without changing the starting torque, which is essential for starting the motor, a short-circuit ring (24) made of an electroconductive material is arranged in the magnetic exciting field that is formed between the rotor (11) excited by the permanent magnets and the stator (10), in a parallel direction to the alignment of the stator (10) and rotor (11). The braking moment generated by the eddy currents in the short-circuit ring (24) can be set by appropriately selecting the geometric dimensions of the short-circuit ring (24), so that the desired reduction of speed of rotation at the operating point may be achieved.
