Abstract: A method for manufacturing an exterior part for a timepiece or piece of jewelry made of Murano glass is disclosed. The method comprises providing a material formed of glass rods (2), also referred to as glass tubes, arranged side by side; applying a multi-cycle heat treatment to consolidate the material and form a blank; and machining the blank to produce the exterior part. The heat treatment may comprise a first cycle (a) consisting of heating the material from a temperature less than or equal to 100° C. to a temperature between 450 and 650° C. at a heating rate between 4 and 12° C./min in order to avoid the formation of air bubbles during the manufacturing of the blank. Also disclosed is an exterior part for a timepiece or piece of jewelry, in particular a watch case, having a structure with few or no air bubbles.

Abstract: The present invention relates to a method for manufacturing an exterior part for a timepiece or piece of jewelry made of Murano glass, said method comprising the following steps: providing a material formed of glass rods (2), also referred to as glass tubes, arranged side by side; multi-cycle heat treatment to consolidate the material and form a blank; machining the blank to produce the exterior part, the method being characterised in that the heat treatment comprises a first cycle (a) consisting of heating the material from a temperature less than or equal to 100° C. to a temperature between 450 and 650° C. at a heating rate between 4 and 12° C./min in order to avoid the formation of air bubbles during the manufacturing of the blank. It also relates to the exterior part for a timepiece or piece of jewelry, in particular a watch case, having a structure with few or no air bubbles.

Abstract: Several watches (1.1-1.4) are placed in an arrangement and interconnected by connecting means (2.1-2.3). The watches (1.1-1.4) have cover glasses (11.1-11.4), dials (12.1-12.4), cases (13.1-13.4), winders (14.1-14.4) and time indicating means (15.1-15.4). The connecting means (2.1-2.3) are e.g. located on a carrier element (20) containing the dials (12.1-12.4) of all the watches (1.1-1.4). The carrier element (20) has preset breaking lines (3.1-3.3) in the form of perforations and cross-sectional reductions between the watches (1.1-1.4), so that said watches (1.1-1.4) can be separated from one another. The arrangement or watches (1.1-1.4) separated therefrom can be used as fashion accessories jewellery, pendants, etc. There are no practical limits to the design of the arrangement and its watches (1.1-1.4). The arrangement can be manufactured in a simple, advantageous manner, so that it is in particular possible to take account of rapidly changing fashions.

Abstract: The invention relates to novel substituted oxazolidines of formula (I) wherein R.sub.1 and R.sub.2 are simultaneously hydrogen or both together are the identical lower alkyl radical, and to the salts thereof in racemic and chiral form, to a process for the preparation of said compounds, to pharmaceutical compositions containing them, and to the use thereof as medicaments. The compounds have a stimulating effect on beta-adrenergic receptors and can be used, inter alia, for the treatment of diseases associated with reversible obstruction of the respiratory tract, typically asthma and chronic bronchitis, and also for inflammation of different origin.

Abstract: The present invention relates to novel oxazolidines of formula (1) ##STR1## wherein R.sub.1 and R.sub.2 are simultaneously hydrogen or both are the same lower alkyl radical or together are 4- to 7-membered lower alkylene, and to the salts thereof in racemic and chiral form, to the preparation of these novel compounds, to pharmaceutical compositions containing them and to the use thereof as medicaments. The compounds have a stimulating effect on beta-adrenergic receptors and can be used, inter alia, for the treatment of diseases associated with reversible obstruction of the respiratory tract, typically asthma and chronic bronchitis, and also for inflammations of different origin.

Abstract: The device comprises a clamping jaw and a two-piece union nut. The clamping jaw is U-shaped in longitudinal section and straddles the end of the pipe so that it surrounds this pipe end from inside and from outside simultaneously. The two-piece union nut is composed of a first part and a second part which is inserted between the first part and the outer leg of the clamping jaw. The second part is provided with a left-hand external thread which meshes with a left-hand internal thread of the first part. Every location to be made tight within the device is sealed twice when the union nut is tightened, so that the connection is completely fluid-tight.
