Abstract: A rodstock barrel drive having a first and second roller gears, each having a toothed section and a gripping surface section, such that the teeth of the roller gears intermesh, causing rotation of one of roller gear to rotate the other roller gear in the opposite direction, so as to draw a rodstock through a space between the gripping surfaces of the pair of roller gears, a ring gear which engages with one of the pair of roller gears, a drive gear which engages with the ring gear, and one or more idler gears which engage with the ring gear, all within a housing, the drive gear being connected to, and rotated by, a motor, which causes the rodstock to be drawn through the roller gears, wherein all the gears are all positioned within, and oriented parallel to, a common plane.

Abstract: The invention provides for compounds having the structure according to the formula I wherein: X is a carbon or nitrogen atom; Ar is phenyl or heteroaromatic ring; R1 is hydrogen, halogen, CN or (1C-4C)alkyl; R2 is hydrogen, halogen or optionally fluorinated (1C-3C)alkoxy; R3 and R5 are independently hydrogen, optionally halogenated (1C-4C)alkyl, optionally halogenated (1C-4C)alkoxy, optionally halogenated aryl(1C-4C)alkoxy, optionally halogenated (1C-4C)alkenyl or hydroxylmethyl; R4 is hydrogen, halogen, optionally halogenated (1C-4C)alkoxy or optionally halogenated aryl(1C-4C)alkoxy; R6 is hydrogen, benzyl, optionally substituted with one or more halogens or (1C-4C)alkyl, or R6 is optionally halogenated (1C-4C)alkyl; each R7 independently is hydrogen, halogen, optionally halogenated (1C-4C)alkyl or optionally halogenated (1C-4C)alkoxy and pharmaceutically suitable acid addition salts thereof for use as glucocorticoid receptor modulators, in particular for treatment of central nervous system disorders.
