摘要:
A heat exchanger, in particular for a heating or air-conditioning system in a motor vehicle, having an evaporator unit to which a refrigerant medium can be supplied via a distribution unit and through which said refrigerant medium flows and around which said refrigerant medium flows after only one diversion (two-block design) at the bottom in a diversion unit, wherein the distribution unit is designed to effect a uniform distribution of the refrigerant medium over the full width of the evaporator.

摘要:
A process for preparing amidines and their salts with inorganic or organic acids comprises reacting the corresponding nitrile with ammonia, C1-C6-alkylamine or hydrazine in the presence of a mercaptocarboxylic acid and in the presence or absence of an in-organic or organic ammonium salt.
摘要:
The invention concerns a transverse connector for osteosynthesis for interconnecting one or several vertebrae, wherein the transverse connector comprises a rod-shaped section for mounting same, and a clamping section for connection of the fixation rod.
摘要:
The invention concerns a bone plate which can be mounted to a vertebra. This is effected by bone screws which engage in the opening of the bone plate. At least one of the openings of the bone plate serves for receiving the screw head of the bone screw and is provided with a surface structure.

An extendable spinal implant has a first outer sleeve and a second outer sleeve coaxially disposed thereto. An inside drive element is connected by means of screws to at least one of the outer sleeves. The inside drive element has an outside thread, and the outer sleeve that is connected to the drive element has an inside thread that fits on the outside thread. The inside drive element rests on a supporting ring, and is rotatably driven with respect to the supporting ring.
摘要:
The invention concerns a bone screw comprising a screw shaft and a forked head into which a correction rod can be fixed. The forked head bears a nut which is connected to the forked head by a bayonet joint.
摘要:
The present technology relates to an improved one-stage method for producing azoniaspironortropine esters such as trospium chloride by reacting an endonortropine compound with an organic dihalogen compound and an a-hydroxycarboxylic acid in the presence of a base and 1,1′ carbonyldiimidazole or 1,1′ thiocarbonyldiimidazole or thionyldiimidazole. The present technology also relates to an improved method for producing nortropan-3-one compounds or their hydrohalides (such as N-benzyltropanone hydrochloride) by reacting an amine and a protected dialdehyde with a basic aqueous solution of 1,3-acetone dicarboxylic acid.
