[EX Q]: Prevodová skrín je vytvorena pro pohon nechráneného ozubeného vence (V) obemykajícího otocnou válcovou nádobu (N), se kterou je venec (V) spojen. Venec (V) je v záberu s dvojicí hnacích pastorku (32) vytvorených na dvojici predloh (3), jejichž hnaná kola (31) jsou v záberu s pastorky (22), ustavenými na hrídeli (2), jehož hnané kolo (21) je v záberu se vstupním pastorkem (1), napojeným na zdroj krouticího momentu. Každý z hnacích pastorku (32) dvojice predloh (3) cástecne obemyká na odlehlé strane od styku s vencem (V) krytka (41). Každé z hnaných kol (31) je opatreno na vnejší strane prevodové skríne pouzdrem (42). Krytka (41) a pouzdro (42) jsou spolu spojeny prepážkou (43) obemykající predlohový hrídel (33), který prepážkou (43) prostupuje. Krytka (41), pouzdro (42) a prepážka (43) jsou spolu spojeny v kryt (4), který je po obvodu spojen s telesem (T) prevodové skríne.
[EX A]: The gearbox is configured to drive an unprotected gear ring (V) surrounding the rotatable cylindrical container (N) with which the outer (V) is connected. The outside (V) is engaged with a pair of driving pinion (32) formed on a pair of originals (3) whose driven wheels (31) engage the pinions (22) provided on the shaft (2) whose driven wheel (21) it is engaged with the input pinion (1) connected to the torque source. Each of the drive pinion (32) of the pair of originals (3) partially encloses the cap (41) on the outward side of contact with the rim (V). Each of the driven wheels (31) is provided with a housing (42) on the outside of the gearbox. The cover (41) and the sleeve (42) are connected together by a partition (43) surrounding the master shaft (33), which passes through the partition (43). The cap (41), the housing (42) and the partition (43) are connected together in a housing (4) which is circumferentially connected to the housing (T) of the gearbox.

[EX A]: The present invention relates to a process for the hydroxycarbonylation of lactones, more precisely of the various valerolactones and their isomers; by reaction thereof with carbon monoxide and water; in order to form the corresponding dicarboxylic acid. More precisely, it consists in reacting carbon monoxide and water with at least one lactone having 5 carbon atoms, the reaction being carried out in the presence of an effective amount of an iridium catalyst and of an iodine-containing or bromine-containing promoter, whereby the promoter/Ir molar ratio being between 0.1/1 and 20/1. This process especially makes it possible to value-enhance gamma-valerolactone to adipic acid.

[EX Q]: Resení je zamereno na pouzití úcinného mnozství prvního inhibitoru retrovirové proteázy, úcinného mnozství druhého inhibitoru retrovirové proteázy, kde uvedený druhý inhibitor retrovirové proteázy jeúcinný vuci alespon jednomu retrovirovému kmenu, který je odolný vuci uvedenému prvnímu inhibitoru retrovirové proteázy, a prípadne dalsích antivirových cinidel, pro prípravu léku k lécbe retrovirovéinfekce, napríklad HIV.
[EX A]:
The present invention is directed to the use of an effective amount of a first retroviral protease inhibitor, an effective amount of a second retroviral protease inhibitor, wherein said second retroviral protease inhibitor is effective to at least one retroviral strain that is resistant to said first retroviral protease inhibitor and optionally other antiviral agents. medicines to treat retroviral infections, such as HIV.
