Abstract: A bottle is disclosed which comprises a neck that forms an upwardly extending mouth from and through which a liquid flows, and a first potion for preventing liquid residue from dripping upon the outer surface of the neck. The first portion includes at least one annular groove formed integrally with the outer surface of the neck near the mouth. The groove is defined by a frustoconical portion of the surface, coaxial to a central axis of the neck and having a diameter that decreases in a generally downward direction. It is also defined by an annulus-shaped portion, lying on a plane substantially normal to the axis and relatively smoothly filleted with the frustonconical portion. The maximum diameter of the annulus-shaped portion is substantially equal to the maximum diameter of the frustoconical portion.

Abstract: It comprises a compound having antifungal activity as active principle, an inert core and a coating including said active principle, and is characterized in that said inert core has a particle size comprised between 50 and 600 &mgr;m, and in that said coating comprises a single layer obtained by spraying, on said inert core, a solution comprising a compound having antifungal activity, a hydrophilic polymer and a non-ionic surfactant. The method consists in carrying out a coating, comprising a single layer, of the inert cores having a size between 50 and 600 &mgr;m, by means of the spraying of a solution composed by the antifungal agent, the hydrophilic polymer and the non-ionic surfactant, at a constant coating speed throughout the whole process; and a single drying step of said coating in the same apparatus.

Abstract: This device comprises a body (2) having outlets (8), and a bonnet (3) housing a rotor (6) being submitted to the action of the inflowing fluid and being connected to a reducing gear (15) activating the closing device. This device is characterized in that the opening of the outlets (8) is carried out with respective angularly sliding shutters (9) being turned by means successively shifting them in opposite directions to thus respectively obtain the opening and closing of the outlets (8). The means shifting the shutters (9) are made up by studs (12, 13 and 14) being provided on the lower surface of the rotary intermediary plate (4) being solid with the reducing gear (15).

Abstract: The provision of a rotational speed controller which is capable of increasing braking torque without a corresponding increase in size, and easily outputting braking torque assumed in the design, and minimizing variations in the braking torque. A casing 6 incorporates a shaft 7 inserted therein, a first rotor 8 rotated together with the shaft 7 in one piece, and a second rotor 10 rotated through the medium of the first rotor 8 and a planet gear 9. A first rotation mechanism for rotating the first rotor 8 is the shaft 7. A second rotation mechanism for rotating the second rotor 10 is a planetary gear mechanism operated in association with the rotation of the first rotor 8.

Abstract: A device is provided for operating inflation and deflation valves of an air chamber of a scuba diver's balancing jacket. The device comprises inflation and deflation valves and a push-button for operating the valves that can be controlled by the diver. The device also has a handgrip projecting forwardly from a side position on a lower edge of the jacket, the push-button being situated on the handgrip.

Abstract: Sheets of rubber-coated fabric are mounted on the cylinders of offset printing presses. An under-packing formed from the combination of an optional flexible supporting sheet and a plurality of flexible packing sheets is interposed between the cylinder surface and the rubber-coated fabric to obtain a predetermined total thickness which varies for different types of printing presses. The thickness of the under-packing is equal to a predetermined maximum thickness. The thickness of the sheets of the under-packing is chosen such that by removing one or more packing sheets from the under-packing, the desired thickness for any specific case can be approximated. A face of each packing sheet which faces inwards, with the exception of the face of the innermost sheet or the supporting sheet if the supporting sheet is the innermost sheet, is treated with an adhesive which, while maintaining the sheets united, enables them to be separated from each other.

Abstract: In the method for threading a tail (7) of a paper or board web through a paper or board machine or a section thereof, or through an aftertreatment machine for paper or board or a section thereof, the tail (7) is prevented from wandering onto the same line with a tail carrier means (8, 9), such as threading ropes, upstream of the draw point of the tail. The tail (7) is guided towards the centre line of the machine by subjecting the tail to an effect of force which tends to move the tail towards the centre line of the machine.

Abstract: A toothbrush incorporating a toothpaste reservoir including a hollow body defining a head member having bristles, the hollow body forming a handle, a toothpaste containing reservoir housed in the handle and a pump arranged in the body to impel toothpaste towards the bristles. The pump is actuated by an outer push slidably mounted on the handle in engagement with the body of the pump. The handle defines an open bottom at a rear end allowing positioning and replacement of the toothpaste reservoir. The reservoir has an open top capped by an open cap extending in form of a cannula towards an inside of the reservoir. A bottom cap caps the open bottom of the handle. Sliding movement of the push toward the head member and relative to the handle causes toothpaste in the reservoir to be drawn out of the reservoir by the pump and directed toward the head member.

Abstract: The method includes the phases of preparation of said ceramic discs once lapped and polished; and deposition of a layer of hydrogenated amorphous carbon (or DLC: Diamond-Like Carbon) on said ceramic discs, said deposition phase including the following stages: exposure of said ceramic discs to vacuum; application of a cleaning plasma on said ceramic discs; application of a first deposition plasma on said ceramic discs; and application of a second deposition plasma on said ceramic discs. The ceramic disc is characterized in that it includes a layer of hydrogenated amorphous carbon deposited directly onto the ceramic disc. Thereby are obtained ceramic discs for utilization in mixer valves of single-lever mixer type whose friction coefficient is lower that that of the ceramic discs currently used, all this without loss of leak tightness, without having to use grease and with a low manufacturing cost.
