Patent DE-3537113-A1 (DE)
Title: Method of controlling a motor for continuously moving a printing carriage in typewriters or office machines
Inventor: JANSSEN REINER DIPL ING
IPC: H02P8/34
Filed: 1985-10-18
Abstract: When using modern typewriters, the level of noise produced by these machines is a significant factor. Normally, the stepping motors which drive the carriage are fed with acceleration-clock pulse sequences and braking-clock pulse sequences by a microcomputer. The carriage movements which are carried out with these pulse sequences are noisy; particularly when positioning takes place without key stroke noise these movements are felt to be disruptive. The invention is based on the object of achieving quiet constant movement of the carriage. This object is achieved in that, after a first carriage step which is produced by a control circuit with pulse sequences in accordance with a start-clock pulse sequence and a braking-clock pulse sequence, the motor is operated with clock pulse sequences according to a constant start/stop frequency, the instruction for the execution of each further carriage step being determined in the interval between two bit pattern changes by the control circuit. As a result, a uniform movement of the carriage without stops is achieved, it being possible to break off the positioning at any time. Therefore, quiet constant operation of the carriage with continuous space at a low clock frequency is achieved, which is very simple in terms of driving technology. <IMAGE>

Patent DE-3620197-A1 (DE)
Inventor: FELDMANN HUGO DR
IPC: B21B13/14
Filed: 1986-06-16
Abstract: During operation of a rolling mill the roll gap and roll shape change, because of the influence of heat, bending of the working rolls or the roll mounting, wear and the like, and must be compensated and/or balanced to make a planar product, particularly a planar rolled sheet or strip. To compensate for these undesirable disadvantageous influences on the operation of the rolling mill frequent axial sliding of the rolls with respect to each other and/or positioning of the working rolls transverse to the plane of the rolled material is required. These undesirable influences are prevented in a particularly simple way and/or are compensated when the contours of the rolls in the initial state and/or unloaded state of the rolling mill are such that the sum of the roll body diameters at each relative axial position of the rolls varies axially from a constant value.

Patent DE-3701364-A1 (DE)
Title: Fire-tube boiler
Inventor: WIESER RUDOLF DR
IPC: F22B7/04
Filed: 1987-01-19
Abstract: The proposal is intended to create a fire-tube boiler fired with gas or fuel oil with a low NOx furnace, in which sulphur can also be removed from the flue gases, if necessary. The basic idea of the invention consists in the arrangement of a bank of water tubes within the fire tube and at a small distance upstream of the burner, in which combustion occurs with simultaneous cooling of the flame. In combination with the addition of cold flue gases to the combustion air, the maximum combustion temperature can thus be lowered to a value of about 950@C, greatly reducing the formation of NOx. The form of the water-tube bank and its clear distance from the burner should be chosen depending on the fuel employed. In this way, flame turbulence and rate of combustion can be influenced so as to favour the maintenance of a maximum combustion temperature of about 950@C. In the case of fuels containing sulphur, sulphur scrubbing of the flue gases can be performed by blowing limestone or dolomite dust into the fire tube.
