Patent DE-4334919-A1 (DE)
Inventor: LIEDTKE RAINER K DR
IPC: A61K9/70
Filed: 1993-10-13
Abstract: Minimal-dose beta-blocker preparations are used for the short-term therapy of transient functional cardiovascular symptoms and produce in the body only those concentrations of active ingredient which do not produce any significant changes in the physiological values in the cardiovascular system under resting conditions for the specific beta-blocker used in each case and significantly reduce adrenergically induced transient stimulation effects, these being oral, transdermal or topical preparations. This makes differential therapy of functional symptoms possible, which does not apply to conventional beta-blocker preparations designed for long-term therapies. This results in an improvement both in the quality of life and in the benefits/risk ratio of the beta-blockers. The duration of therapy also need not be extended beyond the extent necessary for the symptoms because there is no risk of rebound after discontinuation. Thus, another and novel indication made possible is short-term use for primary therapy of sleep disturbances associated with autonomic syndromes, especially also associated with postmenopausal symptoms.

Patent DE-4339946-A1 (DE)
Inventor: SCHEPP KARL DIPL ING
IPC: G01R27/18
Filed: 1993-11-24
Abstract: The invention relates to a method for insulation monitoring of unearthed electrical DC networks (mains) and AC networks having an unavoidable ohmic and capacitive insulation impedance between network and earth, in particular such networks with connected rectifiers or other current converters. This method includes a AC pulse voltage which has alternately different pulse voltage values and is applied as measurement voltage via an ohmic network coupling between network and earth to the network to be monitored. The measurement current flowing between network and earth for each pulse voltage value of the transient oscillation of the network at this pulse voltage value, which current is dependent on the magnitude of the insulation impedance between the network and earth and on the pulse voltage value, is detected directly or indirectly as measured-current measured-value, and the measurement-value difference between two sequential measured-current measured-values is used to determine the ohmic insulation impedance between network and earth. In this case it is proposed according to the invention, in order to reduce the measurement times, to observe for each pulse voltage value of the measurement voltage the time response of the instantaneous-network-dependent transient oscillation process of the measurement current, or a quantity such as a voltage derived therefrom, until reaching the transient oscillation state, and to detect the associated measured-current measured-values directly after reaching the transient oscillation states and to switch over the respective pulse voltage value of the AC pulse voltage immediately to its next pulse voltage value. The invention furthermore relates to a device suitable for carrying out this method, with an AC pulse voltage source (20) which generates a measurement pulse and can be connected via an ohmic measurement resistor (Rm; 22) and an ohmic network coupling (24) between an unearthed electrical network (12) to be monitored and earth (E), and further having an evaluation unit which is connected to the measurement resistor and detects the measured-current measured-value (Um1, Um2) occurring respectively at the end of the transient oscillation process of one of each of the measurement pulses at the measurement resistor and it determines the ohmic insulation impedance (Re) between the network to be monitored and earth from the measured-value difference (Um1-Um2) of two sequential measured-current measured-values respectively. In this case it is proposed, according to the invention, for the AC pulse voltage source to be designed as a switchable voltage source (20) which can in each case generate one of a plurality, in particular two, different DC voltage values as a function of a control signal (S; 36), and for the evaluation unit (28, 34) to be designed such that it detects the electrical transient oscillation process from a DC voltage value across the measurement resistor (Rm; 22) and switches the switchable voltage source to the other DC voltage value at the end of each transient oscillation process.
