Patent ES-397448-A1 (ES)
Title: Copying system featuring combined developing-cleaning station alternately activated
IPC: G03G9/10
Filed: 1971-11-29
Abstract: Electrophotographic copying apparatus has charging, imaging, transferring, precleaning, and erasing facilities in a conventional sense but incorporates a combined developing-cleaning unit that is operable to perform either function at the proper time during the copying sequence. A first version incorporates a photoconductor drum structure surrounded with the necessary electrophotographic elements including a single developer-cleaner unit. Another version incorporates a photoconductor belt movable forwardly and reversely. In either version, cleaning cycles may alternate with developing cycles or be activated following the production of a high number of images on the photoconductor surface. Conveniently, a magnetic brush element forms a contacting surface for conveying toner onto the photoconductor surface during developing and for scavenging residual toner from the photoconductor surface by bringing developer mixture into contact with the photoconductor surface during cleaning. Appropriate changes in biasing of the brush are made during operation.

Patent ES-475630-A1 (ES)
Title: Oscillating-armature motor for electric dryshavers and the like
IPC: H02K33/10
Filed: 1978-12-01
Abstract: An oscillating-armature electric motor comprises an armature which, during operation of the motor, moves along a path of oscillatory movement that includes a substantial range of movement in which the armature poles are located remote from the stator poles. When the poles are remote from each other, the efficiency of electrical to mechanical energy conversion would be low. The stator winding is energized in dependence upon the position of the motor, to avoid wasteful electrical energy dissipation during that part of the armature swing in which the aforementioned efficiency would be low. During the part of the armature swing in which the efficiency is high, the energization is great enough to establish a range of armature movement which goes beyond the high-efficiency armature positions to predominantly comprise low-efficiency armature positions.
