Needle assembly attachable to an injection device, the needle assembly having a reservoir assembly with locking mechanism

A reservoir assembly comprising a reservoir housing, a piston, and a locking plug, both movably arranged inside the reservoir housing; wherein the volume between the piston and the locking plug defines a reservoir cavity. The reservoir assembly further comprising a reservoir outlet; and an actuator configured to act on the piston; wherein the locking plug is configured to be movable from a first position to a second position; wherein in the first position the reservoir outlet is not in fluid communication with the reservoir cavity. The reservoir assembly further comprising an interlock configured to prevent movement of at least one of the locking plug and the piston; wherein the interlock having a locked position and an unlocked position.

Prepn. of hydrazobenzene by catalytic redn. of nitrobenzene - with hydrogen in alkaline alcoholic soln. under turbulent motion

Prepn. of hydrazobenzene by alkaline catalytic hydrogenation of nitrobenzene in alcoholic soln. contg., as alkaline agent, an alkali alcoholate and/or alkali hydroxide, under a press. of >=1 bar at a temp. of =120 degrees C., whilst maintaining the reaction mixt. in turbulent movement. Pref. the reaction mixt. is atomised with H2 in an H2 atmos. and is effected under increasing press. at =90 degrees C., without addn. of any water and using a 1-5C alkanol as solvent, e.g. methanol. High yields of prod. of high purity are obtd. withofast reaction times. Costly purificn. steps required in previous catalytic processes are avoided. The formation of poisoned catalyst in the present process is strongly retarded or even completely avoided.
