Patent DE-3337950-A1 (DE)
Title: Method for driving a thermoprinting strip
Inventor: KORTHAEUER MANFRED
IPC: B41J2/375
Filed: 1983-10-19
Abstract: A method for driving a thermoprinting strip, in which electrical heating pulses are fed to all the printing elements within a predetermined printing time. In order to avoid local overheating of the printing strip and to keep the temporary temperature rise at the printing elements low, the distribution over time of the heating pulses for printing and non-printing printing elements is fixed differently in each case. The printing time is divided up into a fixed number of timing intervals of equal length, of which some are heating phases within which heating occurs and some are cooling phases within which no heating occurs. In the case of non-printing printing elements, in each case heating phases and cooling phases follow one another alternately whilst in the case of printing elements which are printing all the heating phases follow one another and only subsequently all the cooling phases follow one another.

Filed: 1985-08-05
Abstract: A shut-off member (1) according to the invention has a housing (2) which is provided with a hollow space (7) which is connected to a feed and discharge passage (5 and 6 resp.). A sealing part (10) which can be placed against a sealing seat (8) is arranged inside the hollow space (7). The sealing part (10) is arranged on a pivotable lever (14) which can be loaded with a spring force by means of a spring (18) to move it into the sealing postion. Furthermore, the lever (14) is connected to a movable magnet armature (20) which interacts with a fixed magnet core (22) upon actuation of an electromagnet device (21), as a result of which the magnet armature (20) is moved towards the fixed core (22). In order to permit this movement, the shut-off member (1) according to the invention has a surface device (26) which can have, for example, two surfaces (27, 28) pointing towards one another and arranged at an angle to the longitudinal centre axis of the electromagnet device (21). This enables the magnet armature (20) to perform a movement which produces a torque, by means of which the lever (14) or the sealing part (10) can be pivoted, as a result of which the sealing part (10) can be lifted from the sealing seat (8). The advantage of this arrangement lies in particular in its space-saving and compact type of construction, in which the pivotable arrangement of the lever (14) or the sealing part (10) is nonetheless retained. <IMAGE>
