Abstract: Methods and materials for modulating low-nitrogen tolerance levels in plants are disclosed. For example, nucleic acids encoding low nitrogen tolerance-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased[RCL2] low-nitrogen tolerance levels and plant products produced from plants having increased low-nitrogen tolerance levels.

Abstract: The present invention relates to a compacting roller (1) comprising a roller drum arrangement (3) comprising a first roller drum (9) and a second roller drum (11) arranged next to each other, a drive arrangement (13) comprising a first drive unit (15) arranged to rotate said first roller drum (9) and a second drive unit arranged to rotate said second roller drum (11), and a power supply (39). The compacting roller by further comprises a frame (5) which is connected to said roller drum arrangement (3), wherein said power supply (39) is attached to said frame (5) outside each of the first roller drum (9) and the second roller drum (11), and an electronic balancing system (43) for maintaining the compacting roller (1) in an upright position during operation.

Abstract: An eccentric shaft (1) for a compaction machine comprising at least one pair of straight circular cylindrical bearing seats (2,3) arranged on either side of a center of gravity (TP) of the eccentric shaft (1). The bearing seats (2,3) are arranged such that cylinder axes (4, 5) thereof approximately intersect or cross each other at a concave angle (V), less than 179.8 degrees, towards the center of gravity (TP) when the eccentric shaft (1) is at rest.

Abstract: An eccentric shaft for a compacting machine is rotatable about a rotational axis and includes a fixed and movable eccentric mass where the movable eccentric mass cooperates with the fixed eccentric mass in one of the directions of rotation of the eccentric shaft to partly balance the fixed eccentric mass in the other rotation direction of the eccentric shaft. At least one section of the fixed eccentric mass shows a maximal radial extension (UB) in relation to the rotational axis, limited by an arc-shaped curve, which extends to a circle shape, with the diameter (D) showing a distance (A), between the point (P) on the circle-shaped curve that is located closest to the point of intersection of the rotational axis and the section plane, and the point of intersection, from 0 up to 0.1(D).

Abstract: A device for controlling at a fault condition. An apparatus is connected by a connection line to a grid point of a transmission net in an electric power network. A voltage raising apparatus includes a first branch connected to the grid point including a switching element and a second branch including a current resisting means. The voltage raising apparatus includes a computer for signal processing of a sensed fault condition on the network and for affecting the operation of the switching element such that on a fault condition at least part of the current is diverted through the voltage raising apparatus and for evaluation of further actions.

Abstract: A solar collector panel is disclosed for heating of air, in which the conventional insulation material on the back panel facing away from the sun is replaced by a spacing between a permeable back panel and a permeable heat absorber means, so that a heat convection airflow through the back panel and into the interior of the solar energy panel against the temperature gradient prevents the convection heat loss in the opposite direction. The back panel also reduces the radiation heat loss from the heat absorber means. Furthermore, in case the flow of air through the solar energy panel is stopped, the convection-insulation will no longer be effective, and a photovoltaic cell panel placed within the solar energy panel and generating electricity from the solar radiation will not be subjected to the damaging high stagnation temperature of a traditionally insulated solar collector panel.

Abstract: Apparatus for continuously extending ventilating conduits in tunnelling or mining environments includes a tubular store to which a funnel guide is releasably connected. A folded flexible ventilating pipe is received on the store and fastening means are provided to connect an end of the ventilating pipe to the end of the ventilating conduit to be extended. In use, the apparatus is advanced and the ventilating pipe is gradually pulled off the store and unfolded by being passed over the funnel guide.

Abstract: Machine for marking objects, such as steel sheets, comprising a frame, a raisable and lowerable holding cylinder being suspended from the frame, and an embossing head being arranged beneath and connected to the holding cylinder. An embossing wheel shaft being arranged in the embossing head, and a plurality of embossing wheels being arranged on the embossing wheel shaft. The embossing wheel shaft is connected to a driving motor, secured to the embossing head at the bottom, said embossing wheel shaft being formed so as the embossing wheels one by one are pressed down towards the object when the embossing wheel shaft is turned by means of the driving motor.
