Patent JP-H0147848-B2 (JP)
IPC: H01H9/34
Filed: 1982-10-27
Abstract: A gas-cooled magnetic blast circuit breaker made up of a plurality of identical modules. Each module is a flat body made of electrically non-conductive air-permeable material and is formed with an upper and a lower arc breaking chamber, the chambers being separated from one another by a central wall of the body. An electrically conductive stationary contact member is provided in each chamber, each member extending through the body for connection to the power line on opposite faces of the body. There is also provided an electrically conductive dual contact member which is pivotally mounted across the central wall of the body, this dual member having a contact gate at each end, each gate being located in one of the chambers to cooperate with the stationary contact member in that chamber. A pivotable shaft, made of electrically non-conductive material, extends transversely through the body and is connected to the dual contact member to pivot it whereby to move the contact gates simultaneously into and out of electrical junction with the stationary contact members so as to make and break current in the power line. There is provided a coil which is energizable by the current in the power line and which is adapted to create a magnetic field suitable to blow, into the arc chambers, arcs that are formed when the contact gates are moved away from the stationary contact members. The chambers are formed so as to be provided with guideways extending from outside the body to the contact members so that air may be sucked into the chamber by the blown arcs so as to cool the contact members.

Abstract: PROBLEM TO BE SOLVED: To easily recognize whether a pellet is good or not by forming a needle like a rod having an elliptic section and nozzle being a tube having an elliptic section. SOLUTION: A nozzle 10 being a tube having an elliptic section has a top end face 11 at the pellet side. The face 11 is perpendicular to the axis of the tube. A needle 20 is inserted in the nozzle and moves back and forth. The needle 20 is a rod having an elliptic section and has a top end face 21 at the pellet side which is perpendicular to the axis of the rod. As the nozzle 10 and needle 20 have elliptic sections, a defect mark 30 formed with the end faces 11, 21 parallel to the surface of the pellet is also elliptic. This it is possible to form a stable mark because the needle and nozzle never make a cute angles with the pellet surface.

Abstract: A windable clockwork for metronomes comprises a clockwork frame, a stem rotatably mounted in this frame, a spiral spring connected to this stem, a housing enclosing the spring, and a blocking mechanism which prevents the stem and the spring from reverse motion during the winding. The blocking mechanism comprises two coaxially arranged parts made from a plastic material, namely a locking disc and a spring disc. One of these parts is stationarily arranged on the frame and the other is connected to the stem. The locking disc comprises at its periphery at least one integrally formed stop and the spring disc carries at least one likewise intergrally formed, resilient tongue which in one rotational direction of the stem glides elastically past the stop, but in the opposite rotational direction abuts the stop and blocks the reverse motion of the stem and the spring.

Abstract: PROBLEM TO BE SOLVED: To decrease the operating voltage of a liquid crystal device by incorporating a chiral nematic liquid crystal material layer, having a twisted state induced by first and second alignment films in a direction opposite to the twisting of an unrestricted material of the layer. SOLUTION: A first alignment film has an alignment direction 11 at an angle θ in the clockwise direction from with respect to the polarization or absorption direction 10. A second alignment film has an alignment direction 12 at an angle (θ+ϕ) in the clockwise direction, and thereby the liquid crystal layer 8 has a twisting with an angle ϕ in the clockwise direction, namely in the positive direction with respect to the polarization or absorption direction 10. The chiral additive added to the nematic liquid crystal of the layer 8 has twisting effects in the counterclockwise direction, namely in the negative direction. Therefore, when material in the layer 8 is not restricted by the first and second alignment films, the material adopts a twisted state in the counterclockwise direction due to the chiral additive.  The first and second alignment films cause a positive twist angle ϕ of 90 deg. or smaller to be generated, namely in the clockwise direction in the material of the layer 8.

Abstract: The present invention relates to the preparation of aminoalkyl p-hydroxyphenyl ketones. Certain of these ketones are well known as important intermediates in the production of compounds having pharmaceutical activity, for example octopamine or synephrine. The known Houben-Hoesch reaction is a variation of the Friedel-Crafts reaction and involves the condensation of a phenolic substrate with a nitrile in the presence of a Lewis acid catalyst to give a hydroxy-aryl ketone. It is an object of the invention to provide a new or improved process for the manufacture of aminoalkyl p-hydroxyphenyl ketones. According to the invention, there is provided a process for the preparation of an aminoalkyl p-hydroxyphenyl ketone comprising reacting phenol with a nitrile, in the presence of a Lewis acid catalyst, to cause condensation thereof, the process being characterised in that the reaction is carried out in a medium comprising a nitroalkane solvent for the reactants. A preferred but non-limiting feature of the invention is the productiqn of 2'amino-4-hydroxyacetophenones. The present invention is based on the surprising discovery that nitroalkanes are unexpectedly much better solvents for this reaction, being less toxic, giving a better yield and also ensuring a homogeneous reaction medium. The nitroalkanes may also be diluted with a halogenated hydrocarbon solvent, which acts as an inert diluent, thus reducing the amount of nitroalkane used, and making the reaction less hazardous.

Abstract: A continuous motion cylindrical can decorator is provided with mandrels that receive undecorated cans and a deco chain that carries decorated cans through a curing oven. The mandrels are mounted along the periphery of a continuously rotating carrier. Chain speed is much slower than linear mandrel speed and spacing between pins on the chain is much less than spacing between mandrels. Interposed between the chain and the mandrel carrier is a continuously rotating transfer carrier having a plurality of suction holding devices thereto. As the holding devices move through a transfer region they are in single file and receive cans that are blown from the mandrels. In the transfer region mandrel linear speed is substantially greater than linear speed of the holding devices, and spacing between the latter is much less than spacing between mandrels As the loaded suction holding devices move downstream through a pickup region cans thereon are loaded on two rows of pins carried by the deco chain. Linear speed of the holding devices while moving through the transfer region exceeds chain speed, and in this region the holding devices are spaced apart by a distance that exceeds pin spacing. By the time the holding devices reach the pickup region they are arranged in two rows, are spaced apart and are moving at a speed such that they essentially track the moving pins while the latter are being loaded.

Abstract: A self converging, widescreen color picture tube system includes a widescreen, in-line color picture tube having a funnel, an electron gun assembly (28) for three in-line electron beams located in a neck at one end of the picture tube, and a faceplate with a viewing screen at the other end. The picture tube has a wide aspect ratio. A self converging widescreen deflection yoke (40) for deflecting the electron beams in the wide aspect ratio picture tube includes horizontal and vertical deflection windings. The yoke (40) is located by an initial flare section of the funnel and positioned along the longitudinal axis of the picture tube to make the tube reference line and the yoke deflection plane substantially coincident. To achieve substantial horizontal astigmatism correction at the extremes of the major axis of the wide viewing screen, the horizontal deflection winding is constructed to have a generally pincushion-shaped horizontal deflection field over the effective length of the field. The field is modified from that required of the horizontal deflection field in a comparable self converging narrowscreen yoke. The modification is made in accordance with the differences in centerscreen slope angles and S-spacing.
