Abstract: The present invention provides, in part, compounds of Formula I: and pharmaceutically acceptable salts thereof; processes for the preparation of; intermediates used in the preparation of; and compositions containing such compounds or salts, and their uses for treating D1-mediated (or D1-associated) disorders including, e.g., schizophrenia (e.g., its cognitive and negative symptoms), cognitive impairment (e.g.

Abstract: The invention relates to a coupling for connecting and/or holding together two parts, in particular for a bicycle trailer, having a first and a second coupling part which cooperate and can be released from each other, one of which is an insert piece which is connected to one of the parts and the other is a sleeve which is connected to the other part, the sleeve being capable of at least partly engaging around the insert piece, and the first coupling part having at least one locking groove (22, 103). To achieve a constructively simple coupling with a simple handling ability, mounted on or in the second coupling part is at least one locking shaft (4, 96) which has at least one locking segment having in the peripheral direction at least one locking portion (31, 131) and one unlocking portion (32, 132), the locking portion (31, 131) having a greater radial extent than the unlocking portion (32, 132).

Abstract: A solid state voltage regulator for regulating the output voltage in the electrical system of a motor vehicle by controlling the current flow in a field winding associated with a DC generator. Current flow in the winding is permitted only when load current is being supplied by the regulator. The regulator is packaged in a housing which can be mounted directly to the field winding and ground terminals of the generator. The regulator is sepcifically designed for regulating the voltage associated with a motor cycle electrical system.
