Patent DE-3300703-A1 (DE)
Title: Method for controlling the tensile force in elongated material
Inventor: OESTREICH ULRICH DIPL ING
IPC: B65H59/38
Filed: 1983-01-11
Abstract: The method relates to control of the tensile force during winding or unwinding of elongated material whose winding drum is moved by an electrical drive motor, the tensile force being influenced in the desired manner by means of a monitoring device. The drive voltage of the drive motor (AM1) is briefly reduced continuously during winding, or increased during unwinding, such that the tensile force on the elongated material becomes negligibly small. At the same time, the armature current (Jo) of the drive motor flowing in this condition is measured and stored as the basic value of the armature current and, on the basis of the measured basic value of the armature current (Jo), the armature current (Ja) actually flowing is increased during winding, or reduced during unwinding, such that the desired tensile stress is achieved. <IMAGE>

Title: Heat pump with a defrosting device for the evaporator
Inventor: BIRKENSTOCK ALFRED DIPL ING
IPC: F25D21/12
Filed: 1983-01-12
Abstract: In heat pumps in which heat is taken from the air, icing of the evaporator very easily occurs and reduces the efficiency of the heat pump. To eliminate this icing, the heat pump is stopped, or an additional circuit is provided, while a medium is heated in the condenser, and this heated medium is passed through the evaporator, or the heat pump is reversed. All three measures lead to an interruption of the heating system and moreover also to heat being taken out of the heating circuit. According to the invention, it is proposed to provide in a heat pump a heat source, especially an infrared emitter, arranged upstream of the evaporator in the direction of flow of the air and directed towards the evaporator. The ice is thawed from the evaporator by the emitter. At the same time, however, the medium flowing through the evaporator also takes up a considerable portion of the heat radiated to the evaporator.
Patent DE-3301520-A1 (DE)
Title: Control console for controlling the travel voltage of model railway trains
Inventor: SACHTSCHAL HELMUT DIPL ING
IPC: A63H19/24
Filed: 1983-01-19
Abstract: The invention relates to a control console for controlling the travel voltage with automatic, load-dependent follow-up of the travel voltage. In known control consoles, the travelling speed of the model railway is controlled indirectly via the travel voltage, the travelling speed being dependent on the loading of the tractive engine. Thus, when going uphill the speed will be reduced if the travel voltage remains the same and when going downhill it will be considerably increased. In order to obtain a travelling speed which is suitable for the model, it is proposed to form the travel voltage from a pulse sequence of fixed frequency whose pulse duty factor can be changed on the one hand as a function of the position of the travel controller in a freely preselectable manner and on the other hand can be changed via a control unit as a function of the load current of the controlled model railway train. By means of the control unit, a largely constant travelling speed of the model railway is obtained independently of the topographic conditions.

IPC: B65H23/188
Filed: 1984-05-12
Abstract: A transport device for the continuous transport of flexible material, especially photosensitive material in photosetting units, has a pair of driven drawing rollers and, if necessary, a pair of tensioning rollers which are driven in the opposite direction. In order to transport the web material at uniform speed at a certain point, a driven transport roller (11) and two deflection rollers (21,22) are arranged between the pair of drawing rollers (4) and the pair of tensioning rollers (7), the deflection rollers (21,22) being arranged opposite one another at the same distance from a first diametral plane (23) of the transport roller and at a distance from a second diametral plane of the transport roller, which is at right angles to the first one. Furthermore, this arrangement is chosen in such a way that the web material guided round the deflection rollers (21,22) and the transport roller wraps flatly round the transport roller. The deflection rollers connected to one another can be displaced in a deflection plane (27), which is parallel to the second diametral plane, in such a direction that differences the tension of the web material (sections 19, 20) which act on the deflection rollers bring about a displacement of the deflection rollers which compensates for the differences in the tension. <IMAGE>

Title: Hammer-impression mechanism for a typewriter or similar office machine having a pivotable impression hammer
Inventor: MUENSTER DIETMAR DIPL ING
IPC: B41J9/06
Filed: 1984-06-01
Abstract: In known hammer-impression mechanisms having a pivotable impression hammer, its drive devices still consist of many individual parts which have to be assembled and adjusted and are not really suitable for inexpensive mass production. These disadvantages are removed according to the invention in that the pivotable impression hammer (6) can be driven via a solenoid plunger system with an excitation coil (15) and a plunger-type armature (14). In this case, the armature (14) consists of a cylindrical drive part (16) of magnetic material and a cylindrical guide part of non-magnetic material, which parts are mounted displaceably in the legs (19, 20) of a yoke (18). A forward conducting piece (27) which connects the legs (19, 20) of the yoke (18) has an arm (33) with a guide slot (34) for the impression hammer (6). A clean writing image is achieved by this guide of the impression hammer (6) in the vicinity of the impression point. <IMAGE>
