Title: Semiconductor memory with signal change detector circuit
IPC: G11C7/00
Filed: 1988-07-07
Granted: 1993-03-03
Abstract: Semiconductor memory with a signal change detector circuit (24) which deactivates a precharging circuit (9), precharging the data lines (Li, Li), when an address-signal change occurs and then re-activates it after a time delay. In this arrangement, a clock- voltage generator (26) is provided, which generates a clock-voltage (OVL), activating the precharging circuit (9), and which switches this clock-voltage over to a first level, de-activating the precharging circuit (9), when an address-signal change occurs and switches it over to a second level, activating the precharging circuit (9), when an output signal occurs at the sense amplifier (6).

Title: Header for a combine harvester
IPC: A01D41/14
Filed: 1989-01-14
Granted: 1991-12-11
Abstract: In the known combine harvesters, the reaping and/or pick-up headers are wider than the actual working machine and therefore, for road transport, have to be either removed or folded in such a way that movement by road is possible without difficulty. At the same time, the driver's field of vision is often restricted and the individual reaping and/or pick-up headers are of complicated design. To avoid the disadvantages of the known arrangement, it is proposed that only one header part (B) be pivotable on the other header part (A) about an axis (2) pointing in the direction of travel and can be laid onto this, and the two header parts can then be displaced transversely relative to the longitudinal axis of the harvester. <IMAGE>

Title: Process for the preparation of acetic acid and acetic anhydride
Inventor: ERPENBACH HEINZ DR
IPC: C07C51/56
Filed: 1989-06-14
Granted: 1993-09-29
Abstract: For the preparation of acetic acid and acetic anhydride, methanol and methyl acetate are reacted under anhydrous conditions with carbon monoxide in the presence of a carbonyl complex of group VIII noble metals, methyl iodide, and catalyst systems containing alkali metal or quaternary organophosphonium or organoammonium acetate or iodide. The hot carbonylation mixture is depressurised, the evaporated components are added to a first distillation zone, and the remaining catalyst solution is fed back to the reaction zone. In the first distillation zone, the volatile carbonylation products are fractionally distilled; the low-boiling components methyl iodide and methyl acetate pass back into the reaction zone, and a mixture of acetic acid and acetic anhydride is obtained as a bottom product which is separated into the pure components in a second and third distillation zone.

Title: Process for the production of homogeneous finely divided ceramic powders
IPC: B01D1/18
Filed: 1989-09-02
Granted: 1992-07-01
Abstract: The invention relates to a process for the preparation of a homogeneous, finely divided ceramic powder, in which a) a solution or a suspension of substances from which the constituents of the ceramic powder are formed is prepared, b) the solution or suspension is sprayed through a nozzle into a heatable reactor, c) the solvent or suspending agent is evaporated in the reactor and solid residue particles to form, which are dried and converted into the constituents of the ceramic powder by a decomposition reaction or another chemical reaction. It is an object of the invention to indicate a process for the preparation of a finely divided and homogeneous ceramic powder which is crystalline and virtually free from water. The properties of this powder do not depend on the nature of the metal ions employed. In the process, the evaporation of the solvent or suspending agent, the drying and the calcination of the resultant residue particles and their chemical conversion into the desired ceramic proceed in a single process step. The object is achieved according to the invention in that a combustible gas, which is burnt in the reactor, is used to spray the solution or suspension.

Abstract: A ballast control apparatus for an electric discharge lamp (1) comprises a first series circuit including a first winding (5) of an Ac supply voltage transformer (4), a first winding (7) of a ballast transformer (8), a lamp current sensing resistor (11) and the lamp (1). A current sensing transformer (13) has a first winding (12) parallel to the resistor (11). A second winding (16, 9, 14) of the supply voltage transformer (4), the ballast transformer (8) and the current sensing transformer (13) are connected in a second series circuit. A signal voltage proportional to lamp power is derived by adding together the voltages included in the three series-connected second windings (9, 16, 14). A second signal voltage proportional to lamp voltage is derived across the series combination of the second windings (9, 16) of the ballast transformer (8) and the supply voltage transformer (4). The voltage induced in the second winding (14) of the current sensing transformer (13) is proportional to lamp current. A signal voltage indicative of the condition of the lamp load can be derived across the second winding (9) of the ballast transformer (8). These three signal voltages are used to control a DC/AC inverter (2) that energizes the lamp (1) via the supply voltage transformer (4).
