Devant un moustiquaire endommagé, nous avons peu de choix si on veut le réparer. Vous trouverez sous-pli une invention qui remédie à cette situation. Elle consiste à appliquer deux composantes complémentaires décoratives soit une de chaque côté du moustiquaire avec du Velcro ou de la colle. Ce procédé a l'avantage de cacher la technique de fusion des deux parties complémentaires décoratives, augme...

According to the present invention, provided are 1. a process for the preparation of 2-chloro-5-chloromethyl-1,3-thiazole, which comprises reacting 3-chloro-1-isothiocyanato-1-propene with a chlorinating agent, 2. a process for the preparation of 3-chloro-1-isocyanato-1-propene, which comprises rearranging 3-chloro-1-thiocyanato-2-propene in the presence of a salt of one or more than one metals ...

Absorbent pads (2) passing along a feed path (3) advance first on an infeed conveyor (4) at a first pitch (P1) and a first velocity (V1), then on an outfeed conveyor (5) at a second pitch (P2) and a second velocity (V2). The transfer from infeed to outfeed is effected by means of a head (6) disposed between the two conveyors (4, 5), rotatable about a vertical axis (7) and carrying at least one han...

The mobile pincer (1) slides along a vertical support shaft (2) for at least partial penetration into stacked horse hairs (5) in a magazine. An elastic pressure is applied temporarily at an end of the hair extraction assembly against the support surface at the level of the stacked hairs (5). A hair feed is claimed as well. Also claimed is an operation where, before taking a hair, the hook point (8...

The feed delivers lengths of hair into a loom, from prepared magazines (7,11), and has a system to maintain a constant pressure which ensures a clean extraction of each hair (8). There is a pincer (2) in each magazine.

A method for hydroforming a metallic tube comprising primary hydroforming and secondary hydroforming, wherein in the primary hydroforming step, the metallic tube is formed such that a circumferential length of an expanded portion of the primary-hydroformed tube as measured at a wall center region of the expanded portion becomes substantially equal to or slightly shorter than a circumferential leng...

I) dans laquelle R1, R2, A et B sont tels que définis dans la description, leurs is omères optiques, N-oxydes et sels d'addition à un acide pharmaceutiquement acceptable, et leur utilisation comme agents antitumoraux.; BisÄ4,3-bÜcarbazole derivatives of formula (I), their optical isomers, N-oxides and acid addition salts are new. R1, R2 = H or methyl; A = 1-12C ...

The time spent by callers waiting in a queue to speak to an operator are monitored, and in the event of a certain time limit being exceeded, the centre alerts operators based at one or more remote locations to log on to their terminals to provide temporary relief. A telephone operator centre (7) is linked by communication channels to a number of telephone operators (8-12) working at one or more r...

The device operates in real time, retrieving service and call data records from one part of the system and directing them to selected addresses in a second part of the system. Service data records (SDR`s) and/or call data records (CDR`s) are retrieved from a first set of sub-systems within a telecommunications system (preferably the telecommunications part of the network) and then delivered to a ...

A mounting structure wherein, in a semiconductor package mounting position on a wiring board, a package bearing substrate whose external size is substantially equal to or larger than that of the semiconductor package and which has on its upper surface pads for connection to a semiconductor package and on its lower surface pads for connection to the wiring board is arranged, the pads on the wiring ...
