    Abstract: The invention relates to a lock that can be used with a flap, comprising a rotary unit that is made up of a rotary spagnolet that interacts with a closing element (10) and a rotating latch (22). In order to improve operational performance, the rotary unit is provided with a rigid catch (23) that preferably has two counter shoulders running in opposite directions. The output member (35) of a motor (40)—driven gear mechanism is also provided with two corresponding counter shoulders. This enables the motor to provide assistance with closing and, optionally, opening, whereby the rotary unit can be guided in a closing, tilting direction or an opening, tilting direction until the flap is fully closed or opened. The motor (40) comprises a gear mechanism with a group of gears that can be displaced between an engaged position and a separated position. The detent pawl (16) which interacts with the rotating latch (22) is disabled in the separated position, should an emergency arise. When the flap is in a closed or open position, a free area exists between the shoulders and counter shoulders, enabling the flap to be moved manually.

    Abstract: Polytetrahydrofuran, tetrahydrofuran copolymers, diesters or monoesters of these polymers are prepared by polymerizing tetrahydrofuran in the presence of at least one telogen and/or comonomer on a heterogeneous carrier catalyst which contains on an oxidic carrier material as active mass a catalytically active amount of at least one oxygenous molybdenum and/or tungsten compound and, when the precursor compounds of the active mass have been applied to the carrier material precursor, has been calcined at temperatures of between 500° C. and 1000° C. The catalyst used contains a promotor which comprises at least one element or a compound of an element of the 2nd, 3rd including the lanthanides, 5th, 6th, 7th, 8th or 14th group of the periodic system of elements.
