Filed: 1998-11-25
Abstract: The source has a transformer with a main switching unit in primary circuit, and changeover switch, in which main switch is controlled to operate between several states, and changeover switch is able to select between several primary tapping points. An electric current source, especially a welding current source (1) has a transformer (2) with a primary side for connection to an AC source. On the secondary side there is a feed a load with a high electrical current demand. A primary-side main switching unit (8) can be changed over between a switched-on state for the power-moderate, practically unchoked connection of AC supply and primary side, and a switched-off state for the power-moderate strongly choked connection or interruption of the connection of AC supply and primary side of the transformer. A changeover unit (9) in series with the main switching unit, preferably between the main switching unit and the primary side of the transformer, allows a change over between different windings or winding tapping points of the primary side of the transformer. A choke coil is wired in front of the primary side of the transformer, with possible change over between different electrical operating parameters on the secondary side of the transformer. A blocking device (17,18) is assigned to the switching units which blocks the changeover unit in the switched-on state of the main switching unit against changeover and/or the main switching unit during the changeover of the changeover unit against acceptance of its switched-on state.

Patent DE-19919160-A1 (DE)
Title: Marginal pressure controls for contractors plant
Inventor: CHILDRESS DALE B
IPC: E02F9/22
Filed: 1999-04-27
Abstract: The pressure control system (10) and drainage points (21,23) are joined to the system body bore as inlet pressure link as well as a control connection (91) also joined to the system bore. In this a sliding valve piston (29) continuously defines the connection to the drainage point (23) by chamber (17). In its second direction the piston joins the control connection (9,10) to the outlet flow path (67). In its first direction, the valve piston is pre-tensioned in the chamber (17) by the outlet and drainage pressure which in turn is sufficient to attain a pre-set margin pressure. The pressure on the piston can be remotely varied to obtain selected margin pressures in response to a pressure signal. The piston can be reversed in direction by means of a loading pressure which pre-tensions the piston opposite to the direction imposed by the outlet and drainage pressure. This ensures that the margin pressure is sustained right over the pump pressure range. Pre-tension is applied by a spring chamber (72) and spring mechanism (73) also arranged in the chamber.
