Abstract: The invention relates to a method for the MRT representation of a blood vessel (A) and/or of the territory supplied by the blood vessel (A) by labeling the blood, which is guided by this blood vessel (A), by means of continuous arterial spin labeling (CASL), in a specified labeling plane (E). The position of the labeling plan (E) is varied with the provision that a specified location of the blood vessel (A) remains in the labeling plane (E). This enables, for example, a selective labeling of a blood vessel of interest to be saturated by varying the position of the labeling plane.

Abstract: A fiber reinforced floor panel usable in a building comprised of a joist and at least one boot whereby the boot is fixedly connected to an end of the steel joist; a planar section comprised of reinforcing members, whereby a deflection strength of the planar section is higher than a deflection strength of a planar section without the reinforcing members; and a reinforcing material covering whereby the at least one boot and the steel joist are not completely surrounded by the reinforcing material covering.

Abstract: The present invention may be embodied in a sandwich panel having first and second face panels each panel having a first predetermined thickness and being formed of a fiber-reinforced cementitious material. The sandwich panel further includes support frame for supporting the first and second face panels in a spaced apart configuration. The support frame is formed of a fiber reinforced cementitious material that is continuous with the cementitious material of the first and second face panels. Blocks of rigid insulation are embedded in the sandwich panel for defining a structure of the support frame.

Abstract: The present invention relates to snow guns and improvements thereto. The improved snow gun has a large boom which receives liquid under pressure and forces it through small nozzles. The structure does not require high pressure compressed gas or large fan guns, and thus, is much more cost effective to install and operate. In a preferred form, the boom responds to changes in wind direction, which otherwise could reduce the effectiveness of the system.

Abstract: A shut-off unit is disclosed. The shut-off unit is to be used to shut off a drive unit which drives a tubular shaft, the latter shaft being employed, in turn, to wind an awning or a roller blind up and down. More particularly, the drive unit includes an electric motor and a step down gear drive axially aligned therewith and the shut-off unit is adapted to be arrangeable in the drive unit so that the step down gear lies between it and the motor. Additionally, the shut-off unit includes switches for stopping the drive and members for operating such switches which have presettable positions dependent upon presettable positions of a driven part of the electric motor. In accordance with the invention, the aforesaid members are in the form of cams which have lobes and which are adapted to rotate as a function of the movement of the element to be wound and to be drivingly connectable to the central output shaft of the step down gear.

Abstract: A drive unit for awnings and roller blinds is disclosed. The drive unit is adapted to be installed in a tubular shaft upon which an awning cloth or the roller blind is to be wound. More specifically, the unit comprises the following components which are arranged along a common axis: an electric motor; a reduction gear; a shut-off unit with associated setting means; and a coupling member adapted to transmit the torque from the reduction gear to the tubular shaft. In accordance with the invention, the reduction gear is arranged between the electric motor and the shut-off unit. Additionally, a hollow gear wheel is provided as the coupling member. The latter gear wheel is adapted to support and to be drivingly connectable to the surrounding tubular shaft, and is also in driving connection with the reduction gear. With the drive unit designed as above, its axial dimension can be made relatively short.
