Patent DE-3221561-A1 (DE)
Title: Method for quickly positioning a type wheel driven by a step motor
Inventor: PFEFFING KARL-HEINZ
IPC: B41J1/24
Filed: 1982-06-08
Abstract: The method according to the invention permits a quick, precise setting and printing of a selected type character located on the circumference of a type wheel driven by a step motor. By supplying the stator winding of the step motor with current with a constantly repeating sequence of current patterns, the rotor of the motor or the type wheel is rotated from an actual angular position into a desired angular position and when said position is reached the voltage at the stator windings is reduced from a first higher voltage to a second lower voltage. By briefly feeding the motor windings with a higher voltage, a precise positioning of the type wheel is ensured without an appreciable rise in the thermal loading of the motor.

Title: Branch of a data channel for microcomputers
Inventor: SCHWARZ SIEGFRIED
IPC: G06F13/42
Filed: 1983-02-17
Abstract: The data, transmitted in time-division multiplex, of a channel 1 of a microcomputer 4 are branched into the branch channels 7,8,9 without the microcomputer itself outputting branching signals. The microcomputer 4 receives its commands from an external command memory 5. The commands are decoded outside the microcomputer 4 by an additional external command decoder 6, and with the transmission commands of channel 1, branch addresses are formed. The data, transmitted in time-division multiplex, of channel 1 are referred to source, destination and address registers inside the microcomputer 4. These branch addresses are formed in such a manner that the transmission commands, which are allocated to one of the source, destination or address registers in each case in the microcomputer 4, form a branch address in each case. <IMAGE>

Title: Device and method for piston internal combustion engines for the delivery of scavenged-charging-supercharging-fresh gas by direct action of the exhaust gases on the fresh gas
Inventor: SCHNEIDER BERNHARD DIPL ING
IPC: F02B75/02
Filed: 1983-06-01
Abstract: The device described and the method applied are capable of analysing the energy still present in the exhaust gases after the engine outlet aperture up to the fresh gas counter pressure. The delivery of a large volume of fresh gas (air expended) at a high charging pressure is possible. Owing to the direct internal cooling of the device employed, the fresh gas is delivered at a favourable temperature. No high-alloy metals are required for the manufacture, which permits a low design cost. The device according to the method described functions free of inertia. The torque curve is normal. The device is easily adapted to the particular engine type by dimensioning the ram pipe (4) and exhaust discharge connection leading to the exhaust manifold. The method is suitable for two and four-stroke engines, for spark ignition and diesel engines. In the case of spark ignition engines the fuel is first introduced between fresh gas manifold and engine. Either by pressurised carburettor or injection process. <IMAGE>
Patent DE-3320786-A1 (DE)
Title: Partial lining disc brake
Inventor: BAEHRLE FRIEDRICH
IPC: F16D65/853
Filed: 1983-06-09
Abstract: The invention relates to a partial lining disc brake, of which that half of the brake caliper situated inside the rim is, under unfavourable drive conditions, inadequately cooled. In order, in particular, to prevent the hydraulic medium operating the application piston from being overheated, the evaporator of a heating tube, which in its further course extends beyond the disc brake into the air stream, is connected at the end to the brake cylinder. Since the end wall is at the same time designed as part of the wall of the brake cylinder and of the evaporator of the heating tube, this results in an optimum heat transfer through a single-layer wall.

Title: Process for the operation of a furnace, especially small furnace, for solid fuels and furnace for carrying out the process
Inventor: SCHOEN CHRISTIAN O
IPC: F23M9/06
Filed: 1983-09-01
Abstract: In a furnace for solid fuels, especially a small furnace, in which a fluidising of the fuel in a fluidised bed process is not possible as with large furnaces, in order to reduce the pollutant emission, particularly of nitrogen oxides (Nx), the fuel introduced into the lower region of the combustion chamber of the furnace is loosened by devices arranged there, such as revolving stirrers, screws or the like. A gasification and a precombustion or partial combustion thus arise. The rising gases then burn with additional stepwise supply of combustion air in the upper region of the combustion chamber, and the flame temperature can be still further reduced by the introduction of immersed heating surfaces in a known manner.

Title: Circuit arrangement for monitoring the operating state of AC loads used in the external system of a signal box
Inventor: PUENTZNER WOLFGANG DIPL ING
IPC: B61L7/10
Filed: 1983-10-22
Abstract: A circuit arrangement for monitoring AC loads used in the external system of a signal box is disclosed which permits the operating state of such AC loads to be monitored from the signal box and, at the same time, the influence of the line capacity to be eliminated so that even with large feed line lengths a reliable monitoring is possible. The circuit arrangement according to the invention consists of a threshold value circuit which is connected parallel to a measuring resistor arranged in the load circuit and a sensing circuit which is synchronised with the alternating operating voltage and interrogates the output of the threshold value circuit at the times of the alternating voltage period at which the idle current in the load circuit has a zero cross over point. A routing conductor in the input of the threshold value circuit brings about a constantly changing signal at its output which is used for the constant functional monitoring of the threshold value circuit and of further parts of the circuit downstream. <IMAGE>
