Inventor: INABA MICHIHIKO C O PATENT DIV
IPC: H01J9/14
Filed: 1984-05-17
Abstract: A front end element, such as a shadow mask, for a colour cathode ray tube is made from an alloy including iron and nickel as its principal components; and a black oxide layer is formed integrally on the alloy base. The black oxide layer consists essentially of a spinel-type oxide with the formula NixFe(3-x)O4, where x is a positive number less than 3. A front end element constructed in this way produces a higherquality picture because of reduced thermal expansion.

Abstract: A continuously variable power transmission with wide ratio coverage has a variable ratio belt drive (30, 98, 100) in series with a fixed ratio drive (138, 140, 156) which is selectively connectible between the input and output shafts (24, and 94, 96). A pair of selectively engageable clutches (54 and 162) co-operate with the belt drive to provide two continuously variable speed ratio ranges. A transition clutch (64) maintains power flow between the input and output shafts during shifting from one range to the other. The belt drive is controlled between the maximum and minimum drive ratios in each speed range. The belt ratio is held constant while the transition clutch is engaged.

Abstract: In an apparatus for the single-sided or double-sided coating of steel strip, in particular a zinc-plating apparatus, consecutive coating units (1, 2) are inclined to the horizontal and to one another. Disposed in each case between two coating units is a deflection roller (4) which is designed as a contact roller. The slope of the coating units with respect to the horizontal is 1 to 10 DEG , preferably 5 to 6 DEG . A suitable device ensures that the deflection roller (4) between the coating units (1, 2) is always in the correct position. The anode plates (5, 6) can be adjusted to a small gap (7) to increase the current density. For this purpose, the anode covers supporting the anode plates are movably mounted in the housing frame of the coating units (1, 2) and provided with adjusting devices. <IMAGE>

Abstract: In order to reduce the likelihood of incorrect states being transferred from one cross-coupled transistor pair to the next in a frequency divider which comprises at least two such pairs (6a, 7a and 8a, 9a) which are energized alternately by means of a switchable current source arrangement (5) and which are intercoupled to form a cyclic arrangement by means of data transfer transistors (6b, 7b, 8b and 9b) energized from the same outputs (22, 23) of the current source arrangement, the transistors employed are of the insulated gate field effect type. If desired the channel width-to-length ratios of the pair transistors (6a, 7a, 8a, 9a) may be chosen to be larger than the corresponding ratios for the data transfer transistors (6b, 7b, 8b, 9b) in order to improve the high-frequency performance.

Abstract: An improved process for the preparation of N-acetylp-aminophenol. p-Aminophenol is acetylated in an aqueous medium to produce a crude aqueous reaction mixture and N-acetyl-p-aminophenol product is recovered by crystal­lization from an aqueous system comprising the reaction mixture. Crystals are separated from the crude mother liquor which contains residual N-acetyl-p-aminophenol and unreacted acetic acid. According to the improvement, residual N-acetyl-paminophenol and acetic acid are recovered from the crude mother liquor by liquid-liquid extraction with a water-immiscible organic solvent to produce an extract containing N-acetyl-p-aminophenol and acetic acid. The extract is distilled to strip off the solvent and acetic acid.

Filed: 1985-04-17
Abstract: Les dispositifs connus de commande hydraulique par servovalve, en particulier du type buse-palette, présentent l'inconvénient d'être fragiles et très sensibles à la pollution. L'invention permet d'augmenter la fiabilité de telles commandes en associant deux servovalves (20, 30) travaillant chacune sur la même chambre (17) de l'organe commandé de telle sorte qu'une seule servovalve soit active à la fois, l'autre restant au repos en offrant une section de passage fixe. Lorsque le circuit électronique (100) de commande des servovalves détecte une panne du système, il commute la commande sur la servovalve initialement neutre, la servovalve initialement active venant en position neutre. On réalise ainsi un dispositif de commande hydraulique simple, conservant intégralement ses performances après une première panne.

Abstract: A driving and positioning system consisting of a rotor equipped with permanent magnets and of a stator with at least two windings. The windings are connected to an electronic voltage-supply circuit controlled by rotor-position sensors for commutating the current. To improve its adjustment potential by converting the system into one that can be magnetically meshed or latched, the stator is non-ferrous, the disk-shaped stator windings, which are positioned in parallel planes, are overlapped in such a way that the magnetic field generated by the windings and surrounded by the coils is essentially parallel to the magnetic field generated by the permanent magnets, and the rotor-position sensors are each integrated into both windings. A practical electronic voltage-supply circuit for controlling the system is also described. It has two sets of multiplication stages and a set of addition stages in a prescribed layout.
