Abstract: An electrical switching device facilitates selectively controlling a residential power feed. The switching device is configured to couple between a residential electrical-energy meter and a residence. The switching device includes at least one conductor bus bar element, a yoke, and a solenoid assembly. The solenoid assembly includes a biasing member and at least one shorting bar coupled to the biasing member. The at least one shorting bar is movable relative to the at least one conductor bus bar element.

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.

Abstract: The present invention relates to a process for the enantiomeric enrichment of cis-8-benzyl-7,9-dioxo-2,8-diazabicyclo[4.3.0]nonane with the aid of continuous countercurrent chromatography, which is also described as SMB chromatography (SMB=simulated moving bed). In a further aspect, the invention relates to a process for the preparation of (1S,6R)-8-benzyl-7,9-dioxo-2,8-diazabicyclo[4.3.0]nonane using the aforementioned process, which furthermore includes a racemization step.

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.

Abstract: The present invention relates to the use of optically active polymers of N-acryloyl-phenylalanine neomenthylamide as such, in crosslinked form and/or in carrier-bonded form as stationary phases for the chromatographic separation of enantiomers of lactones.

Abstract: The object protection device (M) has an imaging sensor (1) for generating images of an object to be protected and its environment and evaluation electronics (2) for evaluating these images. The evaluation electronics (2) are provided in situ or on the sensor (1) and together with it form an autonomous device (M). Evaluation of the images takes place locally, and in normal cases there is no transfer of the images to a central unit (6). The imaging sensor (1) is formed by a CMOS camera and the evaluation electronics (2) are integrated therein or connected thereto.
