Inventor: LASKA BERND DR
IPC: B60L9/30
Filed: 1996-06-17
Granted: 1997-10-02
Abstract: The circuit contains an inverter associated with each traction motor group contg. at least one input partial current converter (11,21) , an intermediate circuit (ZK1,ZK2) and at least one partial current converter (12,22) on the motor side. In DC mode, the two input current converters of each group are connected together via inductances (L1,L2).

Title: Heat-assisted fumigation, for mills and food processing operations, involves circulating indirectly heated treatment gas with no direct contact between fumigating agent and combustion heater surface
Inventor: BINKER GERHARD
IPC: A01M13/00
Filed: 1999-10-20
Granted: 2001-05-17
Abstract: A heat-assisted fumigation method for mills etc. in which circulating treatment gas is heated indirectly by a heat exchange surface which is itself heated by a combustion heater via an internal air circulation system, thus preventing thermal decomposition of the fumigating agent by direct contact with the heat exchange surface on the burner.  A method for fumigating treatment areas, mainly mills, food processing operations or other areas subject to infestation, by using a fuel-burning heater and circulating the treatment gas, which is heated by passing it through one compartment (11) of a heat exchanger. In this system, the heat exchanger is heated by air circulating through its second compartment (9) and through another compartment (7), which is heated by the heat-exchange surface (6) of the heater's combustion chamber (4), and the treatment gas is circulated in such a way that the fumigating agent in the gas does not come into contact with the surface (6) of the combustion chamber (4) and does not therefore undergo thermal decomposition during fumigation.

Granted: 2001-09-06
Abstract: The invention relates to a conductor bar arrangement (3) that is configured in a multiple-duct manner and is provided with one or more current conductors (5) per duct (phase or pole), whereby said conductors are spatially and electrically parallel. The current conductors (5) are received in current bar holders (7) which consist of parallel strip-shaped support pieces (11, 12, 26) of insulating material and fixing means (13, 14) that connect said pieces. The current conductors are partially situated between the support pieces (11, 12, 26) and are partially situated outside the support pieces (11, 12, 26). A staggered arrangement that is easily accessible from the front of the switchpanel is thus produced. The current bar holders (7) can be produced with good mechanical solidity and in a cost-effective manner using strip-shaped materials having different dimensions.
