Patent EP-0378744-A1 (EP)
Inventor: HUBBARD MARK A
IPC: C21C7/00
Filed: 1989-06-22
Abstract: A vertical first stream of molten metal (21) flows from a ladle into the tundish of a continuous casting appara­tus. A second stream (27) composed of solid, particulate alloying ingredient and a non-oxidizing carrier gas is directed into the first stream with a nozzle (24). The two streams (21, 27) each have unenclosed parts exposed to the atmo­sphere surrounding the ladle and the tundish. The nozzle (24) is cooled with a non-oxidizing gas flowing through a nozzle cooling jacket (31) and exhausted at the outlet end (37) of the nozzle (24). The nozzle interior has a converging down­stream end portion (45) for converging the second stream (27) just before it leaves the nozzle (24).

Title: Process for the preparation of 2-methyl-5-n-alkyl cyclo-pentanones
Inventor: KEIL THOMAS DR
IPC: C07C45/50
Filed: 1989-09-09
Abstract: The known processes for the preparation of 2-methyl- 5-n-alkylcyclopentanones start from conjugated dienes, carbon monoxide and water or alcohols. Disadvantages are working with foreign solvents at high dilution and the low yields. It has now been found that by modification of the hydroformylation conditions, not aldehydes, but cyclic ketones are formed from olefins, carbon monoxide and hydrogen if the reaction is carried out in the presence of a cobalt compound and, if desired, a tertiary amine at 100 to 200 DEG C and 100 to 350 bar. The product is used in particular in the perfume industry.

Abstract: The present invention relates to a control circuit with a step or self-commutation mode, and with speed regulation, of a motor (M) of the type with disc magnet and with angular coders. The step control is ensured by an assembly of two conventional integrated circuits, the first (CI1) delivering a control signal to the second (CI2) serving as power amplifier, the first integrated circuit also comprising means to apply intermittent validation signals to the second when it receives a protection signal indicating that the current in one at least of the phases is greater than a specified threshold (VREF). Control in the self-commutation mode is furnished by a programmable logic array (PLA). The same first integrated circuit (CI1) is used for the speed regulation in the self-commutation mode, this first integrated circuit then receiving at its protection input the signal resulting from a frequency/voltage conversion of the output of one of the angular coders. <IMAGE>

Abstract: This invention provides a wire cut electric discharge machining apparatus which can prevent electrolytic corrosion of a work due to a short-circuit detection voltage applied from short-circuit detection means between the work and a wire electrode and can therefore produce products free from corrosion scratches. The electric discharge machining apparatus includes a relay (20) for selectively short- circuiting a wire electrode (1) and a work (2) through a current supply element (3) or a relay (40) for selectively cutting off the electric connection between short-circuit detection means (8, 9) and the wire electrode through the current supply element, and both relays are responsive to a control output signal from a numeric controller (10). When the discharge machining is finished, the relay (20 or 40) operates in response to the control output signal supplied from a numeric controller and the wire electrode and the work are short-circuited or the short-circuit detection means and the wire electrode are cut off from each other so that the application of the short-circuit detection voltage between the work and the tool electrode is prevented.

Abstract: A process for producing cellulosic deodorant fibers having a remarkable amount of copper and/or zinc hydroxide firmly fixed thereto, which comprises bringing cellulosic fibers into contact with a solution containing a copper and/or zinc hydroxide colloid formed by adding an alkaline substance to an aque- ,ous solution of a water-soluble copper and/or zinc compound. The obtained fibers exhibit an excellent deodorant action whereby various malodorous gaseous components such as hydrogen sulfide, ammonia or mercaptan can be efficiently removed. Although the fibers can be employed by themselves as an excellent deodorant material, they have such an excellent processability that they can be processed into various shapes such as a granule or a sheet and applied to a wide field of deodorization.

Title: Metal oxide ceramic powders and methods of making same.
Inventor: PEDERSON LARRY R
IPC: C01G3/00
Filed: 1989-06-09
Abstract: This invention is directed to the formation of homogeneous, aqueos precursor mixtures of at least one soluble metal salt and amino acid. This produces, upon evaporation, a substantially homogeneous intermediate material having a concentration which would support combustion. A metal oxide powder results on ignition of the intermediate product which combusts same to produce the product powder. An aqueous solution of metal nitrates or other soluble metal salts and a low molecular weight amino acid is coated onto a substrate and pyrolyzed to form a thin ceramic film. The amino acid serves to prevent precipitation of individual solution components, forming a very viscous liquid as excess water is evaporated.

IPC: G01F1/00
Filed: 1990-04-09
Abstract: By means of a suitable clock sequence (A or B), the measuring system is capable of detecting asymmetries in voltage generation as a consequence of incomplete filling of the tube length 1, and of supplying by means of a correction procedure an output signal that is proportional to the through flow. In the case of a full tube length 1, the system operates like a normal magnetically inductive flow meter. If the filling level in the tube length 1 decreases, the electrodes 3a', 3b' installed in the lower half of the tube length 1, and further electrodes if required, can be used exclusively or additionally for measured-value acquisition. Furthermore, for the purpose of improving the measured-value acquisition when a specific filling level is undershot, it is possible to activate an electromagnetic arrangement 15a, 15b specially optimised for partial degrees of filling instead of the normal electromagnetic arrangement 2a, 2b. <IMAGE>

Abstract: A digital phase detector comprises a first input (V) for receiving an output of a voltage controlled oscillator (10) and a second input (R) for receiving a reference signal. When a phase of the first input is in advance of that of the second input or when a frequency of the first input is higher than that of the second input, the phase detector operates to output a first control signal (D) for decrease of an oscillation frequency of the voltage controlled oscillator (10). When the phase of the first input is delayed from that of the second input or when the frequency of the first input is lower than that of the second input, the phase detector operates to output a second control signal (U) for increase of the oscillation frequency of the voltage controlled oscillator (10). In addition, the phase detector is configured to output neither the first control signal nor the second control signal when both of the first input and the second input are at a low level.
