Abstract: A fitting for retaining an electric cord having a generally cylindrical conduit body with a central bore is threaded at first and second ends thereof. The first end of the body has a plurality of fingers extending in an axial direction therefrom, each of the fingers being spaced from adjacent fingers and terminating at a free end thereof in a wedge-shaped gripper extending normal to the axial direction. A flexible, generally cylindrical gland is disposed within a mating recess formed in the central bore of the body. The recess has a lower annular seat formed about the periphery of the central bore proximate the origin of the fingers, the lower annular seat tapering toward the second end as the seat extends radially outward. The recess is further defined by an upper annular seat formed on an inside surface of each of the wedge-shaped grippers.

Abstract: A chemical feeder for use in a water circulation system includes a body, a head attached to the top of the body, and a flow passage extending through the head. A portion of the water flowing through the flow passage is diverted into the body, where the water mixes with chemical tablets contained therein. A strainer is positioned inside the body and a stand pipe connects the strainer to the flow passage. Venturi forces within the flow passage draw the chemical solution from the body and into the flow passage, where the chemical solution mixes with the water flowing therethrough. It is possible to control the concentration of the chemical solution by controlling the flow of fluid from the flow passage into the body.

Abstract: An inhaler for multiple dosed administration of a pharmacological dry powder consists externally of a housing (100,150) and of a protective cap (950) which can be removed from a special mouthpiece (900) fitted on the housing. Arranged on the inside there are a slide rail (200), a dosing slide (300), a shutter (400), a carriage (500), a funnel arrangement (600), a counter device (700), a valve shield (800) and a valve guide (850). Removal of the protective cap (950) initiates the dosing, with a dose received in the dosing cavity (302) being transported to the mouth-piece (900) by means of the dosing slide (300). Only upon application of a defined minimum intensity of inhalation is the shutter (400) moved by the suctioned valve shield (800), as a result of which the dose is released for inhalation. Completed with an electronic module and a controllable nozzle, all inhalation-relevant data can be recorded and the flow conditions regulated.

Abstract: The invention involves a procedure for the catalytic enantioselective reduction of ketones to chiral alcohols. Heretofore, this reaction was carried out batch-wise. Because, in this procedure, one utilizes a catalyst increased in size with polymer, it is possible to carry out the reaction in a quasi-continuous manner in a membrane reactor. In contrast to the state of the art, one thus dramatically increases the operative life of the catalyst.

Abstract: In thin film transistor, an amorphous diamond is used as an ohmic layer formed between an active layer and a source and drain electrodes. Specifically, in a inverse staggered type thin film transistor, a gate electrode and a gate insulating layer are formed on an insulating substrate. On the gate insulating layer is formed an active layer. An etch stopper is formed on the active layer, overlapping with the gate electrode. Thereafter, an amorphous diamond is overlappingly formed on the gate electrode on a resultant structure and then a metal layer is formed on the resultant in which the ohmic layer is formed. The metal layer and the amorphous diamond layer is patterned until the etch stopper is exposed, forming the ohmic layer and a source electrode and a drain electrode.
