    摘要： A process for the preparation of compounds of formula I ##STR1## wherein R.sub.1 and R.sub.2 are each independently of the other hydrogen, C.sub.1 -C.sub.12 alkyl, C.sub.5 -C.sub.6 cycloalkyl or phenyl, and R.sub.3 and R.sub.4 are each independently of the other C.sub.1 -C.sub.18 alkyl, C.sub.5 -C.sub.6 cycloalkyl, phenyl, phenyl which is substituted by C.sub.1 -C.sub.6 alkyl and/or hydroxy, or phenyl-C.sub.1 -C.sub.4 alkyl. The process comprises reacting a compound of formula III ##STR2## with a nitrite in aqueous or aqueous/organic medium to a compound of formula II ##STR3## extracting said compound of formula II from the reaction solution with a solvent, hydrogenating said compound, without isolation, in the cited solvent and in the presence of a palladium catalyst, to the corresponding p-aminophenol, and reacting said aminophenol, without isolation, with cyanuric chloride and a compound of formula HSR.sub.3 or HSR.sub.4 or a mixture of compounds of formulae HSR.sub.3 and HSR.sub.4. The products are obtained in high yield and purity.

    摘要： A pneumatic hammer includes a cylinder tube, a piston received in the cylinder tube for reciprocation therein; a device for alternatingly introducing pressurized air into first and second cylinder chambers on either side of the piston for driving the piston back and forth and an exhaust arrangement for removing spent air from the cylinder into the ambient atmosphere. There is provided a coupling cylinder mounted within the hammer housing and generally coaxially surrounding the cylinder tube along a substantial length thereof. The support cylinder has a plurality of circumferentially distributed longitudinal ribs extending parallel to the cylinder tube. The longitudinal ribs are in contact with an inner surface of the housing and an outer surface of the cylinder tube. The longitudinal ribs define and bound a first longitudinal chamber which is in communication an air outlet port provided in the cylinder tube and a second longitudinal chamber communicating in series with the first longitudinal chamber and further communicating with an exhaust outlet provided in the housing.

    摘要： A vibration damper comprises a housing defining a cavity; a damping mass accommodated for oscillation in the cavity between wall surfaces; and spring elements situated on two opposite sides of the damping mass. Each spring element is in engagement with the damping mass and a respective one of the wall surfaces for positioning the damping mass in the cavity. Each spring element has a shape selected to confer to the spring element a dynamic deformation behavior characterizing spherical bodies. Further, the spring elements, as viewed together, are arranged at least approximately symmetrically with respect to a central axis of the damping mass oriented parallel to the path of oscillation. The vibration damper also includes an arrangement for guiding the damping mass linearly along the path of oscillation.

    摘要： A percussion tool comprising a housing; a tool bit movably supported by the housing for alternatingly executing forward and recoil strokes; a hammer piston supported in the housing and arranged for delivering consecutive blows at least indirectly to the tool bit for effecting the forward strokes thereof; a dampening chamber in the housing; an arrangement for introducing fluid into the dampening chamber for generating a dampening force therein; and a dampening piston supported in the housing and bounding the dampening chamber. The tool bit is connected with the dampening piston for effecting an axial displacement of the dampening piston into the dampening chamber by the tool bit during the recoil strokes thereof. There is further provided a control arrangement carried by the dampening piston for varying the dampening force of the fluid in the dampening chamber as function of a relative axial displacement between the dampening piston and the housing.
