Abstract: A battery charging management system and method for a battery fleet having a plurality of rechargeable, communication-enabled, battery units, includes a charging management base configured for transmitting charging setting information for the battery units, a plurality of user terminals configured for transmitting battery-charging-related user predefinition information, a respective charging control unit in each of the battery units, and a communication connection for data transfer between the charging management base at one end and the battery units at the other end and between the user terminals at one end and the charging management base and/or the battery units at the other end. The charging setting information and/or the user predefinition information includes charging mode information with regard to a plurality of different charging modes for the battery units.

Abstract: An outdoor box is designed for keeping at least one battery pack that supplies an electrically driven garden, forestry, construction and/or ground working apparatus with electrical driving power. The outdoor box is configured to receive at least one charger for supplying the battery pack with electrical charging power. The outdoor box has an electrical line for transmission of electrical power to the charger. The outdoor box has an exchange fan for exchange of outside air outside the outdoor box and inside air inside the outdoor box in contact with the battery pack and/or the charger. The outdoor box has a recirculation fan, different from the exchange fan, for recirculating, inside the outdoor box, the inside air, and/or the outdoor box has a further exchange fan for exchange of the outside air and the inside air. The one exchange fan is designed for being supplied with electrical power at least for the most part by an energy source.

Abstract: A charging device for a battery pack has a housing defining a charging receptacle for accommodating the battery pack. Power electronics are arranged in the housing. A cooling air fan is provided in the housing which draws a suction air flow into the housing via a first air inlet opening and blows the suction air flow out of the housing, as a first cooling air flow via an air outlet opening. A battery air flow flows through the battery pack and enters as a first cooling air flow via the first air inlet opening. A further suction air flow is drawn into the housing from surroundings of the housing via a second air inlet opening formed in the housing. The further suction air flow is formed as a second cooling air flow separate from the battery air flow. The power electronics are situated in a flow path between the second air inlet opening and the cooling air fan. The second cooling air flow, after cooling the power electronics, is supplied to the cooling air fan.

Abstract: An assembly for handling a fluid, comprising a valve and a controller. The valve has at least one revolving valve element and a coupling device. The coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device. The controller is adapted for controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position.

Abstract: A component part of a microfluidic valve adapted to be coupled with a microfluidic device, the microfluidic device having at least one port coupled to a flow path of the microfluidic device, the component part comprising a first revolving valve element having a first interface with the microfluidic device and a second revolving valve element having a second interface with the microfluidic device and being located within a through hole of the first revolving valve element.

Abstract: The fertility of female mammals can be improved by dispensing once or within a short time repeatedly a high dosage of tyrosine. The dispensation can be carried out at will intravenously or orally.

Abstract: A roller press for compacting and briquetting bulk material having rollers, each comprising a core, segments arranged adjacent one another around the surface of the core, adjusting springs by which the segments are fixed on the roller core in the circumferential direction, clamping rings having frusto-conical faces on projections which abut frusto-conical faces on projections on the segments, and clamping bolts extending through the clamping rings and passing between the longitudinal edges of the segments. Each clamping ring is provided at its inner circumference with adjusting spring grooves parallel to the axis of the clamping ring and the adjusting springs for the segments extend parallel to the axis of the roller beyond the end of the segment to such an extent that they engage in the adjusting spring grooves in the clamping ring.

Abstract: An improved ruminant feed containing rumen stabilized particulate proteinaceous feed material which is unstable in solutions having a pH value smaller than 4 and relatively stable in solutions having a pH value larger than 5, said feed composition including at least one non-proteinaceous nitrogen compound. The non-proteinaceous nitrogen compound is present in a weight ratio of 0.1 to 10.0 based upon the weight equivalents of nitrogen in the rumen stabilized albuminous component.
