    Abstract: Prior art terminals with operating buttons and a contact member movable against the force of a spring are relatively bulky and complex. It is proposed to provide a part of a curved leaf spring as the contact member having at least one aperture fitted in such a way above the conductor guide that an edge of the aperture acts as the contact member. This design also permits the contacting of thin conductors.

    Abstract: The invention relates to a method for treating vapours and condensates which arise during the production of polycondensates from bisphenols or high-value phenols by esterification and/or transesterification with alkyl or aryl esters of at least bivalent organic or inorganic acids. According to the invention, the treatment is carried out in a plurality of condensates and/or distillation columns which are connected in a step-by-step manner behind each other, each distillation column comprising a connected condensate. The dew point and the pressure in each condensate are adjusted such that in each step, monomers, oligomers or decomposition and transformation products are removed.

    Abstract: A safety cabinet has a plurality of walls defining a front open side and a pair of doors pivotal about respective horizontally spaced axes on the walls between a closed and an open position. Guides in the cabinet are each associated with a respective one of the doors, and respective links each have a front end connected to a respective one of the doors and a rear end shiftable front-to-back in a respective one of the guides. A connector extends between the rear ends of the links and shifts front-to-back with them. A closer is operatively engageable with the connector, and a spring applies bears on the closer to urge it against the connector for pushing same into the rear end position and closing the doors. An actuator normally holds the closer out of engagement with the connector during movement of same between the front and rear end positions.
