Abstract: To reduce the risk of breakage and yet ensure good electric and thermal conductivity, pull-off strength and long service life of the connection, when connecting a contact element to a conductor (1) by crimping, the inner surface of the crimp section (6), in contact with the conductor (1), is provided with deformations that are grooves (2) and ribs running crosswise and obliquely to the longitudinal axis of the conductor (1).

Abstract: A spray gun with electrokinetic charging of powdered material for the purpose of electrostatically coating workpieces with a powder coating. As the powder flows pneumatically through a channel of insulation material in the form of an annular gap, the plastic powder to be applied is charged by superimposition of triboelectric effects with ionization processes initiated by these effects at a passive ionizer electrode, and completed by friction against a semiconductive insert within the annular gap. Thus, the effective area of the electrostatic induction ionizer is expanded, the charge on the powder is increased and spark-like sliding discharges in the flow channels as well as dielectric breakdowns of the channel wall are prevented.

Abstract: An apparatus for the electro-kinetic charging of powder-like materials having a pair of supply channels, an input zone for each channel, one for the powder dispersed in a gas flow and one for another gas flow and which are shaped as dual annular nozzles with a pipe-shaped separating wall therebetween acting as an electrostatic ionizing electrode and made from an electrically semiconductive material having anti-sticking properties and, wherein the adjoining flow channel is formed as an annular channel by a pipe from an insulating material, and a centrally arranged rod, wherein the ratio between rod and pipe diameters is on the range from 0.75 to 0.9.

Abstract: The disclosure relates to a broad band coupling arrangement with coupling point switches in ECL technology, whereby a plurality of coupling point switches are formed by a corresponding plurality of linkage elements which are integrated on one chip. In order to reduce the power comsumption, a switching transistor is inserted in the operating voltage supply of each chip, said switching transistor only being conductive when at least one linkage element of the appertaining chip is selected. The disclosure can particularly be employed in the distribution of video signals.

Abstract: The disclosure relates to coupling point switches in ECL technology. The coupling point switches are each formed by means of a differential amplifier circuit with two emitter-coupled high frequency transistors; in order to reduce the power consumption, a switching transistor is inserted in the common emitter current circuit, the switching transistor only being conductive when the appertaining coupling point is driven into the through-connected condition. The disclosure can particularly be employed in the distribution of video signals.

Abstract: An intermediate amplifier arrangement for communication lines in which the intermediate amplifier is divided into at least two partial amplifiers each having a capacitance between the outer conductor of the coaxial transmission line and the amplifier and connected to feed supply voltages such that the amplifiers are uncoupled from each other as to high frequency and utilizing low inductance and low resonance capacitors so as to obtain very low power consumption and large cyclical attenuation.
