The present invention relates to an orthodontic adjustment system (1) and a method for arranging an orthodontic adjustment system (1).

The invention relates to a rectifier diode which has a base (2) and which can be pressed into a provided opening of a rectifier arrangement.

The orthodontic adjustment system (1) has at least one adjustment unit (2) for securing on a tooth surface (50).

The orthodontic adjustment system (1) preferably comprises a treatment arch (30) that runs through a passage (400) of at least one adjustment unit (2).

The air straightening system comprises an air straightening device having a plurality of cells for straightenening the air flow prior to the air flow reaching the product.

The invention relates to an image reversion system (500) which enables an image reversion and beam transposition of a plurality of observation beam paths (503a, 503b, 504a and 504b) to be carried out simultaneously.

An air straightening system for staightening circulating air and air circulation system (10) mounted within a chamber (12) are provided.

Submerged launch and recovery systems are not new.

The inventive system is suitable as an image reversion system in an additional module for operational microscopes used in ophthalmoscopy due to the low overall height thereof.

The feeding device (10) is connected to a raising device (32) that serves to transfer a film core (12) out of a horizontal position and into a vertical position.

The film core (12) is removed from the raising device (32) by means of a transfer device (36) and is transferred to the film roll winding machine.

A direct synchronous rectification system characterized by a reduction in the number of operational components as compared with conventional systems is disclosed.

This system of injunctive relief is described in more detail below (section X).

The last three youth and children vests must always include the straightening system.

Non-linear inductor(s) are used to reduce the percent total harmonic distortion of the harmonics in the line currents in the input side rectifier system of an ac drive system.
