Abstract: The aim of the invention is to provide a method for gasifying organic materials which is simple to carry out and requires minimal equipment and which produced an undiluted gas of high calorific value. The inventive method should eliminate the need to use fluid beds and heat exchangers with high temperatures on both sides, with the heat being transferred from the furnace to a heat-carrying medium in a particularly defined way. To this end, the feed material is divided into a volatile phase and a solid carbon-containing residue in the pyrolysis reactor by circulating a hot heat-carrying medium. After the reaction agent has been added, said volatile phase is converted into the product gas by further heating in the reaction area, also using the heat-carrying medium. The solid, carbon-containing residue is separated from the heat-carrying medium in the separating stage and burnt in the furnace. The heat-carrying medium is heated by the waste gases of the furnace in the heating area and then returned to the reformer and then the pyrolysis reactor.

Abstract: A jewelry display stand including a vertical post assembly mounted on a base. A plurality of arms, serving as hanger elements for jewelry or other merchandise, radiate from the post. The arms co-operate with anti-removal elements on the post that prevent merchandise from being removed from the spokes. In one embodiment a ring engaging the tips of the arms provides the anti-removal elements. In another embodiment the anti-removal elements are a set of spokes above the arms. Either the arms or the spokes are movable up and down and are spring-biased upwards, to a position in which the arms are separated from the anti-removal elements and merchandise can be removed from or placed on the arms. A cap on the post engages the movable elements, holding them down, and keeping the arms engaged with the ring or spokes. A slot in the cap allows one arm or spoke to rise to the non-engaging position, and the cap is rotatable about a vertical axis so that the slot can be aligned with any selected arm or spoke. Thus, merchandise can be removed from only the selected arm, reducing the risk of pilferage.

Abstract: The present invention aims at providing a display driver and a display device using such a display driver which can prevent the deterioration of the display quality of a display section by suppressing the drop of a power source voltage between respective display drivers. When a COG-mounted liquid crystal display panel whose mode can be changed over between a master mode and a slave mode is driven by a plurality of display drivers, the display driver (120) at the master side which is set in the master mode supplies the power source voltages for driving liquid crystal generated by a voltage generating part (210-M) due to input switching parts (220-1M, 220-2M) to power source voltage input terminals (200-1S, 200-2S) of the display driver (130) at the slave side using operational amplifiers (230-1M, 230-2M). The display driver (130) at the slave side generates the power source voltage for driving the liquid crystal from the power source voltage supplied from the power source voltage input terminals (200-1S, 200-2S) by input switching parts (220-1S, 220-2S) using the voltage-follower connected operational amplifiers (230-1M, 230-2M). <IMAGE>

Abstract: The rotor position of a synchronous motor is determined, in that for a plurality of current vectors distributed over one electrical rotation of the synchronous motor, the amount of the current vector which is necessary to attain a defined deflection of the rotor is determined. The position of the rotor may be calculated from the position of the minima of the amounts thus determined, taking into account the direction of rotation of the rotor. The engagement of a brake may ensure that grooving forces and machine vibrations play no role for the method to determine the rotor position.
