  • Patent number: 7396341
    Abstract: A locking-stressing-mechanism with spring-actuated output drive and a counter with which an apparatus of this kind is fitted, accommodated in a two part housing the two parts of which are mounted to be rotatable relative to each other, can be blocked by means of a pre-stressed leaf spring. The leaf spring is initially accommodated in a recess in the wall of one housing part. As soon as the permitted number of actuations has been reached a push rod pushes the leaf spring out of its resting position. The leaf spring then jumps into a recess in the wall of the other housing part and the two housing parts can no longer be rotated relative to each other. The push rod may be mounted on the pointer of the counter. This blocking device can only be overcome by the application of a force which is sufficient to destroy the device. The device is suitable for blocking a high pressure atomiser or a needleless injector with which a fluid is atomised to form an aerosol or a fluid is injected into a biological tissue.

  • Patent number: 6835857
    Abstract: The present invention relates to an improved process for preparing 4-(6-bromohexyloxy)-butylbenzene by reacting 4-phenylbutanol with 1,6-dibromohexane in the presence of a base and a phase transfer catalyst, wherein 4-phenylbutanol in a diluent is metered into a mixture consisting of 1,6-dibromohexane, a base, a phase transfer catalyst and a diluent, and the use of the 4-(6-bromohexyloxy)-butylbenzene thus prepared for producing salmeterol in a method known per se.

  • Patent number: 6825176
    Abstract: The present invention generally relates to an assay for identifying inhibitors of Human Papillomavirus (HPV), comprising: a) contacting a HPV E2 transactivation domain with a probe to form a E2:probe complex and measuring a signal from said probe to establish a base line level; b) incubating the E2:probe complex with a test compound and measuring the signal from said probe; c) comparing the signal from step b) with the signal from step a); wherein said probe is a compound of formula (I) or its enantiomers or diastereoisomers thereof: wherein R1, A, X, W, Y, R3 and R4 are as defined herein; or a derivative thereof, wherein said derivative is a probe of formula (I) labeled with a detectable label or an affinity tag, wherein wavy lines represent bonds of unspecified stereochemistry; and wherein said signal is selected from: fluorescence, resonance energy transfer, time resolved fluorescence, radioactivity, fluorescence polarization, change in the intrinsic spectral properties, luminescence

  • Patent number: 6811970
    Abstract: A method for measuring heterodimerization of HIV RT, which comprises the steps of: a) providing a first solution comprising p66 subunit homodimers in the presence of a dissociation agent; b) contacting the first solution with p51 RT subunits and incubating in the presence of a reassociation buffer to allow association of a complex of p66/p51 RT subunits, wherein one of the subunits comprises an affinity tag and the other of the subunits comprises a detectable label; c) contacting the incubate of step b) with an affinity medium under conditions that enable the p66/p51 complex to bind to the affinity medium; and d) determining the amount of complex formed by measuring the level of detectable label bound to the affinity medium (or by measuring the reconstituted RT polymerase activity).
