Abstract: A magnetic rotor (3) of suitable configuration is supported so that it is free to rotate in a vessel or tube, whereby the rotor is in direct contact with the stirred or pumped medium and is rotated by the rotary magnetic field of an electromagnetic drive system (2). The rotary magnetic field is generated by a number of coil segments (6,6',6",6"') controlled by phase-shifted alternating currents (8,8'), whereby the coil segments are arranged on an annular core (4) of ferromagnetic material. With the appropriate arrangement and control of the coil segments, the rotor located near the ring axis turns very smoothly, since the presence of individual magnetic poles can be dispensed with. The annular design of the core also allows stirring to be performed in a vessel with a central outlet at the bottom. The electromagnetic drive device (1) together with its core and winding, which require only one cable lead connection to the power source arrangement (1), can be of compact, leakproof and chemically resistant design.

Abstract: A process for producing stabilized molten carbonate fuel cell porous metal anodes by impregnating a porous metallic anode in an aqueous solution having dissolved therein a water soluble salt of a structure stabilizing agent; drying the impregnated porous anode to evaporate free water and form hydrated salts of the stabilizing agent on the surface of the metal particles, further heating the impregnated dried porous anodes to dehydrate the hydrated compounds on the surface of the metal particles, and heating the porous anodes to a temperature of about 600.degree. to about 700.degree.

Suitable stabilizing agents include water soluble salts of chromium, zirconium, aluminum, and mixtures thereof. The porous metallic anodes produced according to this process provide stability against sintering and creep resistance during molten carbonate fuel cell operation.

Abstract: An apparatus for measuring the temperature in a heating system comprising a cooking pot with cooking material positioned on a hot plate where a radiation receiver is arranged at a distance from the wall of the cooking pot and aligned with it, which receiver produces a temperature measurement signal corresponding to the temperature of the cooking material in the cooking pot. The temperature measurement signal is derived from a detected radiation area on the wall of the cooking pot which corresponds to the radiation measuring field of the radiation receiver. The effect of different distances of the cooking pot from the radiation receiver is automatically compensated for by aligning the center axis of the radiation measurement field at an acute angle to the support surface of the hot plate, so that the distance of the center of the detected radiation area from the bottom of the cooking pot increases with an increasing distance of the wall of the cooking pot from the radiation receiver.

Abstract: The collision of birds with aircraft is prevented by means of at least one light source installed on an aircraft which produces light flashes. The frequency of the light flashes produced thereby is varied during at least one cycle time period. The frequency of light flashes is advantageously continuously increased one or more times in a range of from approximately 0.1 Hz to 3.0 Hz, and the maximum frequency may then be maintained. Two such light sources are preferably visible to the birds.

Abstract: A non-mixed vertical tower anaerobic digester and anaerobic digestion process provides passive concentration of biodegradable feed solids and microorganisms in an upper portion of a continuous digester volume and effluent withdrawal from the middle to bottom portion of the digester, resulting in increased solids retention times, reduced hydraulic retention times, and enhanced bioconversion efficiency. In addition, due to passive concentration of solids, the non-mixed anaerobic digester accommodates high solids loadings and provides separation of microbial phases within the continuous digester volume to achieve substantially complete bioconversion of biodegradable feedstock components.

Abstract: The invention relates to a display unit in which characters, symbols or pictures are created in matrices composed of lines and columns by the presence or absence of graphic display elements, and the display elements are moved into a visible or invisible position simultaneously in the one direction, such as columns, and subsequently in the other direction, such as lines, by a composing unit activated, for example, electromagnetically, by a data processing unit. The display elements are moved past the composing unit, and when, during this movement, the next axis (column or line) to be set has reached a setting position, an impulse is sent back to the data processing unit releasing the activation of the composing unit. With a transport belt having display elements which are only partially punched out, the display elements can be moved by the composing unit in a way that they will be positioned in front of or behind a separating strip during subsequent rotation of the transport belt.
