摘要:
A process for increasing the optical purity of a mixture of enantiomers of nefopam uses a substantially single enantiomer of a O,O-diaroyltartaric acid as a resolving agent, via a bisnefopam salt of the acid. This salt is new.

The invention relates to a medical instrument for removing objects from narrow passages, which instrument has a shaft on whose distal end a hook-shaped curvature is configured. In order to produce a medical instrument that is easy to operate and ensures reliable removal of objects even in cramped space conditions, it is proposed with the invention that the distal end of the shaft can be converted between an essentially linear form and a form that has a hook-shaped curvature.
摘要:
A device (22) for heating a food product (P). The device (22) including an oven enclosure (52) at lest one magnetron for emitting microwave energy and a microwave energy focusing device (68, 70, 72) associated with at least one magnetron (56, 58, 60, 62, 64 and 66) and adapted to focus microwave energy towards the food product. The magnetron(s) is/are disposed external the enclosure (52) and the microwave energy focusing device(s) is/are disposed internal the enclosure (52). Also disclosed is a food product support device (116) of a substantially truncated conical external shape with a first larger base surface (118) adapted to be positioned adjacent the base of the oven enclosure and a second smaller supporting surface (120) adapted to support a food product (P) in a position vertically displaced from the base of the oven enclosure for heating and a sloping side surface (122) extending between the base and support surfaces. The food product (P) is able to exit the oven enclosure by sliding down the side surface (122) when pushed from the support surface towards (120) an opening in the oven enclosure. Also disclosed is a food product positioning and ejection device (138) adapted for reciprocal movement towards and away from an opening in the oven enclosure.
摘要:
A device for supporting at least one arm of an operating person during a surgical or medical operation comprises at least one supporting element for supporting the at least one arm of the operating person, the supporting element being arranged at a carrying structure for carrying the at least one supporting element, wherein the carrying structure is configured such that the at least one supporting element can be lowered or raised for adjusting the height of the operating person's arm. The carrying structure comprises at least one carrying arm, which is pivotable about at least one at least approximately horizontal pivot axis such that pivoting of the carrying arm raises or lowers the at least one supporting element. The carrying structure further comprises a mechanical control system acting on the pivotability of the at least one carrying arm in the upward direction differently from the downward direction.
