Abstract:
A method and apparatus for the concurrent treatment of multiple oral diseases and defects while promoting general oral hygiene utilizing direct current electricity. Electrodes are used to deliver a direct current to the gingival tissues of a mouth in order to achieve a number of therapeutic, prophylactic, and regenerative benefits. These benefits include killing oral microbes, increasing oral vasodilation, reducing oral biofilm, improving oral blood circulation, reversing oral bone resorption, promoting oral osteogenesis, treating gum recession, and fostering gingival regeneration. Other benefits include the treatment of gingivitis, periodontitis, and oral malodor, and other systemic diseases correlated with oral pathogens.
Abstract:
The invention relates to an electrochemical or electric layer system, comprising at least two electrode layers and at least one ion-conducting layer disposed between two electrode layers. According to the invention, said ion-conducting layer contains at least one ion-conducting solid electrolyte and at least one binder at the grain boundaries of the at least one ion-conducting solid electrolyte for improving the ion conductivity over the grain boundaries and the adhesion of the layers.
Abstract:
The invention relates to an electric handheld tool having a cover (2) that can be removably fastened to the spindle neck and that can rotate at least partially about an axis parallel to the spindle axis (54) or in line with the same, acting together with a counter-catch (30) on the spindle neck for preventing rotation by means of a spring-loaded catch (26) on the cover (2) in different rotary positions, wherein the cover (2) can be slid onto the spindle neck and then brought into a rear grip position, wherein the catch (26) can be deflected in the axial direction of the spindle axis (54) on the cover in a spring-loaded manner, and the counter-catches (30) are provided on the axial end face (32) of the spindle neck, wherein a stop (70) acts together with the catch (26) in a first position and limits the axially spring-loaded deflection of the catch (26), such that the catch (26) and counter-catch (30) are held in engagement, and releases the axial deflection in a second position such that the catch (26) and the counter-catch (30) are out of engagement and can rotate relative to each other.
Abstract:
An electrode (300) for an energy store (200) is proposed, comprising a porous carrier body (301) composed of an electrically conductive carrier material, said carrier body having a coating (304) composed of active material, wherein the coating (304) is formed in such a way that it does not block the pores (302) of the carrier body (301).
Abstract:
Die Erfindung betrifft eine Anordnung zum Bestimmen eines Ladezustands eines Akkumulators (3), die außer dem eine oder mehrere galvanische Zellen umfassenden Akkumulator (3) eine Messvorrichtung zum Erfassen von Änderungen mindestens einer nichtelektrischen physikalischen Größe eines aktiven Materials (22) des Akkumulators (3) aufweist. Die Erfindung betrifft ferner ein entsprechendes Verfahren zum Bestimmen eines Ladezustands eines Akkumulators (3).
Abstract:
According to the invention, during a treatment, in particular on the coating of the surfaces of threads (2) etc, an optimal and as uniform as possible a treatment surface may be formed by means of a particular roller configuration for guiding the thread. The thread (2) is guided to the roller (1) for the thread treatment by means of an inlet (5) and a deflection roller (6) and from there removed after the processing through an outlet (7) from the processing chamber (9). The roller (1) for tensioning and continuous transportation of part sections of the thread (2) are arranged such as to include a first angle of 0.5° to 10°, preferably 2° to 3°, and the rollers for compensating the length differences in the part sections of the threadlike object caused by the first angle are arranged at a skewed second angle to each other.
Abstract:
Die Erfindung betrifft ein Gehäuse (6) zur Aufnahme einer Energiespeicherzelle (1) mit einer flexiblen Hülle (3). Das Gehäuse ist aus einem Material mit gegenüber der Hülle höherer Steifigkeit. Das Gehäuse weist eine Fensteröffnung (7) auf einer Flächenseite im Bereich der flexiblen Hülle (3) sowie zwei Öffnungen für die Stromableiter (2) der Energiespeicherzelle (1) auf.
Abstract:

Die Vorrichtung umfasst einen Blechrahmen, in den die Energiespeicherzellen (1) gesteckt sind und in dem ein Kühlkörper (7) angeordnet ist.
Abstract:
The present invention is preferably directed to a dispenser of the type sold by 3M ESPE under the trade name Pentamix and as also described above. Such a dispenser preferably comprises at least a first and a second compartment for a first reservoir and a second reservoir, respectively, the first and the second reservoirs containing a first and a second component for the dental material, respectively. It further preferably comprises a first and a second plunger driven by a first drive for advancing the first and the second components from the first and the second reservoirs, respectively. Moreover, a dynamic mixer driven by a second drive for automatically mixing the first and second components to form the dental material from the first and second components is provided. Such a dispenser further preferably has a dispensing portion or mixing tip for dispensing the mixed dental material. The present invention is more particularly directed to a dispenser or method adapted for advancing and mixing at least one dental material, comprising at least one drive which is operated on a predetermined, non-uniform drive speed profile. Preferably an advancing speed profile is provided for advancing the components and/or a mixing speed profile is provided for mixing the components, and either profile may be a "drive speed profile" as that term is used herein. More preferably both profiles are provided.
Abstract:
The invention relates to a method for charging an energy accumulator, consisting of several cells connected in series and/or in parallel. According to said method, a plurality of charging voltage values are detected at constant intervals, a first charging voltage value being compared with at least one second charging voltage value. The charging of the energy accumulator ceases when the first charging voltage value is greater than or equal to the second charging voltage value.
