Title: Cooling of high power electrical transformers
Inventor: ROGE GABRIEL
IPC: H01F27/02
Filed: 1984-02-20
Abstract: A high power electrical transformer is mounted on rollers (4) and has electrical connectors (2,3).

Abstract: A process for developing an electrostatic charge image using a magnetic toner powder (6) consists of applying this powder as a uniform layer onto a magnetic brush consisting of a multiple magnetic core (3) and a revolving cylinder (4) surrounding this core. From this cylinder the toner powder is transferred onto the electrostatic charge image (on drum 2). The magnetic core (3) of the magnetic brush is itself also rotatably driven, the frequency of the alternating voltage applied to the core exceeds 15 kHz (is pref. 18-20 kHz) and the thickness of the single-component toner (a2) is at least equal to the width of the gap (a1) between revolving cylinder (4) and receiving drum (2). Pref., the amplitude of the alternating voltage exceeds 1400 (1600) Vpp. Pref., the toner on the revolving cylinder revolves with this cylinder, i.e. the two cylinders revolve in the same direction at the contact gap. Additionally, a constant voltage of 30-60 V may be superimposed on the alternating voltage at a polarity the same as that of the charge image.
