摘要:
A first and a second object (1 and 2) are joined with the aid of a joining element (8) including at least in the region of its distal and proximal ends (8.1 and 8.2) a thermoplastic material. Two blind holes (5 and 6) facing each other are provided in the two objects (1 and 2) and the joining element (8) is positioned in the blind holes such that its distal and proximal ends (8.1) are in contact with the bottom faces of the blind holes and such that there is a gap (9) between the two objects (1 and 2). This assembly is then positioned between a support (3) and a sonotrode (4). The sonotrode (4) and the support (3) are forced towards each other, while the sonotrode (4) is vibrated, thereby liquefying at least part of the material having thermoplastic properties, there, where the joining element ends (8.1 and 8.2) are pressed against the bottom faces of the holes (5 and 6) and allowing the liquefied material to infiltrate into pores of the hole surfaces or unevennesses or openings provided in the hole surfaces.

The invention relates to a disposable packaging, for the distribution of at least one nutritional preparation, based on a nutritional liquid, comprising at least one closed chamber, containing the nutritional liquid, with means for housing a sub-assembly for aspiration and mixing of the venturi type and means for sealing the package. The invention is particularly characterized by a duct, passing through the base seal, said duct provided for a venturi nozzle which permits the extraction of the nutritional liquid inside the packaging by piercing or removal of the seal. The invention is particularly of application to the production of hot and/or emulsified drinks of the cappuccino type or similar.

A water purification device includes an expandable water collecting device having a variable volume, wherein at least part of the surface of the water collecting device includes a filter area, the filter area being permeable to water and allowing water to enter the water collecting device when the filter area is submerged in water. The device further includes a mechanically driven expansion means for exerting a force for increasing the volume of the water collecting device and thereby drawing water through the filter area into the water collecting device. In use, the water collecting device is submerged and the expansion means is released, drawing water into the water collecting device through the filter membrane.

The invention concerns a device (3) for dispensing a liquid, the device being connectable to a container (4) containing the liquid and detachably connectable to a base station (5) having drive means (524), the device (3) comprising a liquid duct (69) and means (6) actuated by drive means (524) for effecting passage of liquid through the duct (69), characterized in that the device (3) comprises a cutter (101) for piercing a tamper resistant foil (41) positioned across the outlet of the container (4) and that means (103) for actuating the cutter are operable from outside the device (3).
摘要:
An inhaler for delivering a powdered inhalation formulation from a blister strip having a plurality of blister pockets. The used part of the blister strip with emptied blister pockets is coiled by a clock spring or pushed into a helical channel. This results in a simple construction, in which the used blister strip is kept separate from the part that has not yet been used.

The invention concerns a timepiece comprising a mainspring with constant torque, having a balance spring and a balance wheel, the balance wheel (7) oscillation being maintained through an escapement mobile element (2) by moving a fixation point of the balance spring (6) when the oscillator passes through the oscillator impulse point, bringing about a circular motion of said balance spring (6) fixation point about the oscillator, thereby driving in rotation in time the mainspring-escapement assembly (2,6,7).
摘要:
A piezoelectric drive having an excitation piezoelement (10) and a resonator (2). The resonator is coupled to the piezoelement and is in interactive connection with a body (3) to be driven. The resonator (2) has a mass distribution that is designed such that, as a result of an excitation oscillation by the piezoelement (10), the resonator (2) begins to asymmetrically oscillate in several directions dependent on the frequency of the excitation oscillation. The asymmetric oscillations, via the interactive connection, displace the body to be driven into a directed movement.
摘要:
A mechanism for setting and winding of a clockwork, with a winding button spindle, rotatable around its arbor and displaceable in the axial direction, and with a first gear arranged at a distance from the winding button spindle, rotatable around its arbor and displaceable in the direction of its arbor. The rotational movement of this first gear is operatively connected to the rotational movement of the winding button spindle via at least one additional gear. The axial displaceability of the first gear is operatively connected to the axial displaceability of the winding spindle via a first connection device, so that the first gear can be engaged in the axial direction with additional clockwork parts by axial displacement of the winding spindle. An additional connection device produces an operative connection between the winding spindle and a second gear, so that the second gear, as a result of axial displacement of the winding spindle, is pivoted around an arbor of a third gear operatively connected to the second gear.

The object is to provide a lid (11) that does not cause environmental pollution. The lid (11) comprises a lid body (12) formed of a plastic sheet and a pull-cap (14) formed of a plastic sheet. The lid body (12) covers a top end opening of a cylindrical container body (15) and has an opening-for-drinking (16). The pull-cap (14) has a sealing portion (20) for covering the opening-for-drinking (16) of the lid body (12) and for sealing the periphery of the opening-for-drinking (16), and a pull-tab portion (21) formed integrally with the sealing portion (20). The sealing portion (20) has an easy-to-peel layer. A holding groove portion is formed in the lid body (12) at a location different from the location of the opening-for-drinking (16), and a pull-cap holding section for holding the pull-cap (14) peeled off is formed at the holding groove portion. Since the pull-cap (14) can be held by the pull-cap holing section after it is peeled off, the pull-cap (14) is not likely to be thrown away carelessly after the pull-cap (14) is peeled off the lid body (12) to open the beverage container.
