  • Publication number: 20100143859
    Abstract: A dental face-bow comprising a base part, two side arms that extend from the base part and two positioning elements, for example ear pieces for positioning the face-bow on the head of the patient. The positioning elements are situated on the side arms and can be displaced in relation to the side arms. The face-bow is also provided with a displacement device which is used to simultaneously displace the two positioning elements in relation to the side arms. To drive the positioning elements, a dial, which is situated on the base part, can be used for example to turn a flexible shaft that is rotatably mounted inside the two side arms. the two ends of the shaft are equipped with gears that co-operate with gear rods on the positioning elements. This arrangement permits the face-bow to be placed on a patient extremely gently, as there is in particular no relative displacement of the side arms.

  • Publication number: 20090096558
    Abstract: An electrical switching device facilitates selectively controlling residential power. The switching device is configured to couple between a residential electrical-energy meter and a residence. The device includes a solenoid assembly, a yoke, and at least two conductor busbars. The solenoid assembly includes an electrically-activated solenoid that is coupled to an actuator assembly. The actuator assembly includes a biasing mechanism and a plunger. The yoke is coupled to the actuator plunger such that the plunger is substantially centered relative to the yoke. The biasing mechanism is coupled to the yoke to bias the yoke away from the solenoid. The yoke includes at least two shorting bars that are oriented in a mirrored-arrangement on opposite sides of the actuator plunger.

  • Publication number: 20080200731
    Abstract: Polyhalogenated cinnamic acids and cinnamic acid derivatives are prepared by reacting diazonium salts accessible from polyhalogenated anilines with acrylic acid or acrylic acid derivatives in the presence of a homogeneous, palladium-containing catalyst at about ?5 to about +100° C. Some of the cinnamic acids and cinnamic acid derivatives obtainable in this way are new. Cinnamic acids and cinnamic acid derivatives which can be prepared according to the invention can be used for the preparation of indanones which are precursors for agro- and pharmaceutical chemicals and for substances having liquid-crystalline properties.
