Abstract: An electromagnetic impact drive includes two electroconductive helical springs in meshing relationship, with their fixed ends supported on an abutment and their movable ends joined to an electroconductive armature. Electric terminals connect the fixed ends to a electricity source for feeding a current to flow from one of the electric terminals via an associated one of the helical springs in a first direction towards the armature and from there in an opposite second direction via the other one of the helical springs to the other one of the electric terminals so that adjacent windings of the helical springs repel one another by an oppositely directed force pair when an electric circuit is closed. A control device is provided to open and close the electric circuit with the electricity source.

Abstract: The invention relates to a closure with a thermal safeguard function, comprising a closure body (1), which is used to seal a cavity (10) that is to be closed; a fusible safeguard element (2), which is inserted into the closure body and which keeps closed, at least indirectly, a through-opening (1.1), which is formed in the closure body. The inventive closure with a thermal safeguard function is characterized by the following features: the closure body comprises a bushing (3) provided with a continuous bore (3.1); the bushing is inserted into the through-opening of the closure body at an axial end (1.3) in such a way that the continuous bore and the region of the through-opening that is axially adjacent to the bushing are aligned flush with each other; the fusible safeguard element completely fills the continuous bore of the bushing over the entire cross section thereof along a given axial length.

Abstract: A hydrodynamic machine with a turbo coupling comprising primary and secondary wheels together forming a torus shaped workspace, which can be filled with a working medium. A temperature-sensing device installed in a component, which rotates when the machine is operating, and sending a temperature —dependant signal. A stationary monitoring device connected to the temperature sensor in a remote query connection, and having means for creating a temperature measurement correction depending on the heating rate progression of the sensed temperature.

Abstract: The invention relates to a hydrodynamic machine, in particular a turbo coupling, comprising: a primary wheel; a secondary wheel; the primary wheel and the secondary wheel together form a torus-shaped workspace, which can be filled with a working medium; a temperature recording device, which is installed in a component that rotates when the machine is in operation, and sends a temperature-dependent signal. The hydrodynamic machine, in particular the turbo coupling, according to the invention is characterized in that the signal comprises information for determining the absolute temperature of the working medium and/or a predetermined reference point in the rotating component.

Abstract: A portable bait bucket includes a built-in handle allowing it to be easily carried from place to place. The inventive bucket includes an internal chamber accessible by an opening in its top closed by a pivotable door having a plurality of openings allowing air to enter the chamber to maintain some level of oxygenation for the water contained therein. On a forward face of the bucket, an opening is provided that may be closed with a plug to allow the user to extract bait from the inner chamber of the bucket. The inner chamber is divided into two sub-chambers by a divider that includes a water pervious wall allowing water to flow from one sub-chamber to the other. One sub-chamber is connected to the top opening and the forward facing opening. This first sub-chamber contains the bait. The second sub-chamber is not connected with the forward facing opening or the top opening.

Abstract: Imidazole-4,5-dicarboxylic acid is prepared by a process in which imidazole is reacted with formaldehyde, and the reaction mixture is treated with nitric acid.

Abstract: Liquid epoxy resin hardeners are mixtures of 2-ethyl-4-methylimidazole, ethyldimethylimidazole and/or diethylmethylimidazole isomers which can also contain other alkylimidazoles, and can be produced by distillation of the products obtained in the dehydrogenation of 2-ethyl-4-methylimidazoline.

Abstract: The disclosure concerns a pumping apparatus for working fluid, in a hydrodynamic coupling, or the like. Working fluid is stored in a sump and is to be lifted by a spinning disc to an elevated container from which the working fluid is then directed back into the spinning disc. The periphery of the spinning disc picks up the working fluid from the sump and carries it around to spary it up toward a deflector at the top of the housing which deflects the fluid into the container. A groove-like duct encloses the lower quarter of the disc for directing the fluid back toward the surface of the disc. The disc has a trapezoidal cross-section peripheral groove for further carrying the fluid beyond the top exit of the duct so that the fluid may be thrown toward the deflector at the top of the housing.

Abstract: New imidazole-copper complex compounds having a good fungicidal action, fungicides containing these compounds as active ingredients, processes for their manufacture, and their use for combating fungi.

Abstract: A process for the manufacture of 5-hydroxymethylimidazoles by reaction of an imidazole with formaldehyde or an oligomer of formaldehyde in aqueous hydrochloric acid solution containing from 5 to 18% by weight of hydrogen chloride, at from 80.degree. to 160.degree. C., if desired in a closed system under pressure, followed by isolation in the form of its hydrochloride of the 5-hydroxymethylimidazole obtained.

Abstract: 1-Hydroxymethylimidazoles which are unsubstituted or alkyl-substituted in the 2-position, their manufacture and their use as chemical intermediates, e.g. for other imidazole derivatives or for the drug cimetidine.

Abstract: 1-Alkyl-5-nitroimidazoles are prepared by reacting a 5-nitroimidazole with an alkylating agent in the presence of an aliphatic carboxylic acid. The products are intermediates for the production of dyes, textiles auxiliaries and insecticides.

Abstract: An elevation and leveling adjustment arrangement for accurately locating pressure-to-current transducers, used in monitoring blood pressure during and post surgery, at an appropriate reference point relative to the patient. The pressure-to-current transducers are mounted to a platform or base which also has provided thereon level indicating means and optical means. The optical means in combination with the level indicating means is arranged to indicate when the base is properly leveled and the pressure transducers are at the same elevation as the reference point marked on the patient. In the case where an optical sighting means is employed, the reference point is directly viewable thereby. The platform further includes leveling adjust means which adjustably couples the base to a telescoping elevation adjust means, the latter of which provides fine elevation adjustment of the platform.

Abstract: A patient care system for monitoring respiratory distress problems and providing therapeutic treatment comprising, a sensor for generating patient derived respiratory activity signals, detecting an apnea episode from the signals, and providing in response to a detected apnea episode, stimulation of the patient by a momentary inflation of a pneumatic means adapted for placement under the patient to raise the patient and induce loss of equilibrium for startling the patient into a natural respiration pattern.

Abstract: A patient care system for monitoring respiratory distress problems and providing therapeutic treatment comprising, a sensor for generating patient derived respiratory activity signals, detecting an apnea episode from the signals, and providing in response to a detected apneic episode, stimulation of the patient by a momentary inflation or deflation of a pneumatic means adapted for placement under the patient to raise or lower the patient and induce thereby a loss of equilibrium for startling the patient into a natural respiration pattern.
