A timepiece includes an outer caseband 3 formed entirely in one piece of a hard material which likewise includes a hub member 4 providing the timepiece dial, and a metallic inner caseband 16. An annular step 10 for positioning and glue fastening a crystal 9 surrounds the hub member. This arrangement gives the hard material the rigidity necessary to resist forces acting thereon during manufacture and subsequently when the watch is worn.

The setting stem 27 of a watch is engaged in a radial hole 29 of an inner metallic caseband 16 with a packing 31 to assure fluid tightness. An outer caseband 3 of hard material includes a radial hole 28 aligned with the hole in the inner caseband. A crown 32 of the same material as the outer caseband may cap the stem. This arrangement enables uniting the wear resistant properties of the hard material with good fluid tightness of the stem.

A suture anchor retaining a suture is fixated in hard tissue, in particular in bone tissue, using any per se known method and is then secured using a securing element including a material having thermoplastic properties, which is liquefied in situ and made to penetrate the hard tissue in which the suture anchor is fixated. The securing element is e.g. a thermoplastic plug or thermoplastic sleeve which is anchored above the suture anchor in a mouth area of the same hard tissue opening. Alternatively the securing element is a thermoplastic pin which is introduced into an inner cavity of the suture anchor, wherein the material having thermoplastic properties is liquefied in this cavity and, in a liquid state is pressed through passages connecting the cavity with outer surfaces of the anchor.

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.
摘要:
A method for joining bodies by melting down a joining element. The joining element acts on a surface of one of the bodies and penetrates the surface as a result of a directed force. Once in a penetrated condition, a mechanical excitation is generated such that during further penetration of the joining element into the one body, the advance is maintained through the directed force and the melting down is maintained through the mechanical excitation. Molten or melted material is hydraulically displaced into the bodies.

The invention is a medicament magazine having at least one medicament chamber for use in a powder inhaler, wherein the magazine is formed from two foil strips applied to one another and the at least one medicament chamber is formed between the foil strips. The medicament chambers have an internal structure (3) which comprises in its interior a space for receiving a powdered medicament and stabilises this inner space against external mechanical influences. In another embodiment in which the internal structure preferably also has a stabilising function, the structure has means for opening one foil strip. In addition, the medicament chamber contains a retaining device which holds the internal structure on the medicament magazine after the medicament chamber has been opened.

The invention concerns a medicine dispensation device, in particular a multi-dose powder inhalator, for the dispensing of individual doses of medicine as depicted in exemplary FIG. 1. Therein a number of medicine chambers are contained in a medicine magazine shaped like a continuous loop. The medicine chambers form groups in such a manner that a mouthpiece reaches the different groups by an essentially complete rotation of the medicine magazine. This enables several medicine chambers—typically one, two or three—to be situated between two successive intake positions, which allows for a high density of medicine chambers and thus creates an inhalation device, which can be handled comfortably even when containing a great number of individual doses.
摘要:
A device (3) for metering a base liquid and mixing this base liquid with a diluent to prepare a food product, has means for connecting it with a container (4) containing the base liquid, the device (3) comprising: a diluent inlet (71), a mixing chamber (80) for mixing the base liquid with the diluent. Air inlet means are provided for selectively having ambient air enter the device and guiding it to the container (4). Control means are provided for selectively metering the base liquid into the mixing chamber and for selectively enabling an air flow through the air inlet means only during periods when no base liquid is metered into the mixing chamber.
摘要:
A drive unit for the movement of an active element with respect to a passive element, wherein the active element includes a resonator and at least one excitation device for exciting oscillations of the resonator. The resonator includes contact regions for exerting forces onto the passive element. The active element may be driven with respect to the passive element by way of oscillating movements. The resonator includes at least two arms, preferably a pair of arms. The at least two arms of an arm pair, proceeding from a connection region of the resonator, are formed on the same side of the resonator. In each case the contact regions are formed at the outer ends of the arms, wherein the contact regions may be moved to and away from one another by way of oscillating movements of the arm pair. Thereby, a relative movement of the passive element with respect to the active element may be effected.
