Abstract: A control device for a bicycle is arranged or can be arranged on the handlebar of the bicycle and serves to wirelessly drive at least one electronic, electrical, electromechanical or electrohydraulic component of the bicycle. The control device includes an operator control arrangement which has at least one manually operable operator control element and is designed to respond to operation of the operator control element and to output electrical signals which represent the operation. The control device also includes at least one electronic circuit arrangement comprising a radio communication circuit and a control circuit which is connected or can be connected to the operator control arrangement. The control device also may include at least one antenna which is connected or can be connected to the radio communication circuit or which is integrated into the said communication circuit.

Abstract: An operating device for operating an electrical bicycle component includes a base element, an actuating element and a housing. The base element is configured to be non-rotatably mounted about a bicycle handlebar. The actuating element is rotatable relative to the base element from a neutral position to a first actuating position. The actuating element may be pre-loaded into the neutral position. A first electrical contact switch may be actuated when the actuating element is moved from the neutral position to the first actuating position.

Abstract: An operating device for operating an electrical bicycle component includes an annular base element, annular actuating element and first electrical contact switch. The annular base element is configured to be non-rotatably mounted about a bicycle handlebar. The annular actuating element is rotatable relative to the annular base element from a neutral position to a first actuating position. The annular actuating element is pre-loaded into the neutral position. The first electrical contact switch is actuated when the annular actuating element is moved from the neutral position to the first actuating position to generate a first sensory feedback.

Abstract: Disclosed are various methods for reducing levels of elemental sulfur within gypsum products such as wall board. Gypsum sometimes includes increased levels of elemental sulfur. Such sulfur can be corrosive and otherwise harmful at elevated levels. The disclosure contemplates reacting the elemental sulfur with copper to copper sulfide. This reaction has the benefit of reducing the levels of elemental sulfur present within the final gypsum product. The copper can be added at any of a variety of locations in the manufacturing process. This is a very efficient method for reducing elemental sulfur in the production of gypsum products.
