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 apparatus has an input pocket into which a stack of sheets is inserted. At least the sheet to be picked from the stack by the picking device is transported by means of a feed device to a picking device which then picks one sheet from the stack at a time. To improve singling quality, a presingling device is provided which first transports only part of the stack to the picking device. In order to ensure that stacks of different-sized sheet material are singled reliably, an aligning device is provided which transports at least the sheet to be picked from the stack in the direction of a defined stop and thus aligns the sheet against said stop. The aligning device preferably cooperates alternatingly with the feed device. To increase singling reliability, a pressure plate is provided in the presingling device for acting upon the presingled partial stack with a certain pressure.
Abstract:
An end stopper (10) for liner systems for pipe and sewer rehabilitation with a liner which is arranged between two end stoppers (10) and can be acted upon by a pressure medium and can be applied reversibly to the circumference of the end stopper (10), is characterized in that the end stopper (10) is composed, in cross section, of a plurality of profile parts (100, 101, 102, 103, 104, 105) which are of part annular and/or part tubular shape and are conical, wherein at least one profile part (100) has a configuration that tapers conically from the inside to the outside.
Abstract:
The invention relates to a method and a kit for preparing a radiopharmaceutical, the method comprising the steps: elution of a 68Ge/68Ga-Generator using hydrochloric acid as an eluent for obtaining a generator eluate comprising 68Gallium, feeding the generator eluate through a cation exchange cartridge, which collects the 68Gallium, separating the used eluent, eluting the 68Gallium from the cation exchange cartridge using a solution comprising sodium chloride and hydrochloric acid and feeding the resulting eluate into an aqueous precursor mixture comprising at least a labelling precursor thereby forming a reaction solution.

Abstract:
A device for mixing and dispensing dental materials is provided, comprising a drive shaft for driving a mixer. The mixer is placeable on the drive shaft in a first and a second position, wherein in the first position a guiding section of the drive shaft is mated with an engagement section of the mixer, but an engagement section of the drive shaft is not engaged with the engagement section of the mixer, and in the second position the engagement section of the drive shaft is also engaged with the engagement section of the mixer.
Abstract:
The invention relates to a handle configuration for a door, in particular for a motorized vehicle door, with an outside handle (1) mounted such that it can pivot, which is arranged on the outside on the type of exterior door fuselage (3) that has a concave external handle recess (2), where the outside handle (1) has a first (10) and a second bearing arm (20) arranged on the inside with the first bearing arm (10) mounted around a rotational axis (11), the outside handle (1) has face surfaces (5) in each of the areas of the first (10) and the second bearing arm (20) which face the exterior door fuselage (3) and with a gap (4) that exists between the face surface (5) and the exterior door fuselage (3). According to the invention, it is provided that the outside handle (1) is rotatably mounted in a guideway (12, 31), which is fundamentally matched to the contour of the concavity of the handle recess (2), by means of which a tolerance compensation can be achieved by moving the outside handle (1) along the guideway (12, 31), without a resulting contact of the outside handle (1) with the exterior door fuselage (3).
Abstract:
A handle for a moving part of a motor vehicle, particularly for a door, hatch, tailgate, or the like, having a retaining element which can at least partially be arranged on the outer paneling of the moving part, and having a support which can be arranged on the inside of the moving part and which is attached to the retaining element by means of an attachment means.
Abstract:
A drive system for an entry/exit facility with at least one pivotably and/or slidably mounted door, ramp, tread or the like of a passenger transport vehicle, the system including at least one actuator or drive motor and a mechanical system driven by it and/or a gear unit for effecting the pivoting or sliding movement of the door, ramp, tread or the like, with an absolute value encoder for acquiring a momentary position during the pivoting or sliding movement, where an evaluation unit is configured to compare the momentary position with at least one reference position stored in a non-volatile memory of the evaluation unit in order to generate an output signal dependent thereon, and the absolute value encoder is flange-connected to a pin that fixes the pivoting movement of the door, ramp, tread or the like, and the gear unit includes a first reduction gear unit, a second reduction gear unit, and a controllable coupling is provided between the reduction gear units.
