Abstract: A magnetic resonance method is described for forming a fast dynamic image with an automatically generated grid of essentially orthogonally arranged grid lines by a saturation information induced over the object to be imaged. Therefore a first set of parallel saturation planes is obtained by applying a first nonselective RF pulse with a flip angle of 90°, an intermediate magnetic field gradient pulse in direction of the spatial modulation, and a second nonselective RF pulse with a flip angle of 90°. A subsequent spoiler gradient pulse is applied in the direction of the magnetic field gradient for slice selection. Subsequently a second set of parallel saturation planes is obtained in the same manner by inverting one second RF pulse with respect to the first RF pulse. Further the first and the sets of saturation planes are subtracted from each other to obtain a grid free of any contribution of relaxation components of magnetization.

Abstract: Compounds are used as catalysts according to general formula (1) M+x(C(SO2CF3)3)x, whereby x is equal to 1 or 2; M represents one hydrogen or alkaline metal atom when x equals 1; and M represents one alkaline-earth metal atom when x equals 2. The invention also relates to a novel Mg compound of formula (1).

Abstract: A hose end dispenser for selectively spraying water with and without an additive such as liquid fertilizers and insecticides. The hose end dispenser includes a main conduit having opposite proximal and distal ends and a bypass conduit with a pair of opposite ends fluidly connected to the main conduit. A first of the ends of the bypass conduit is positioned adjacent the proximal end of the main conduit. A second of the ends of the bypass conduit is positioned adjacent the distal end of the main conduit. A container is fluidly connected to main conduit between the first and second ends of the bypass conduit. A rotatable dispensing ball is interposed between the container and the main conduit. A bypass valve is positioned adjacent the proximal end of the main conduit and the first end of the bypass conduit for selectively opening and closing passage of fluid through the main conduit and the bypass conduit, the bypass valve.
