摘要:
A camshaft adjuster for an internal combustion engine having hydraulic medium guides. The adjuster can include a setting unit that can be controlled by a control unit using these guides in the adjuster, wherein the setting unit is for adjusting an angle of a camshaft. This setting unit has an inner body coupled to the camshaft so as to rotate with it, and an outer body that is mounted to rotate relative to the camshaft via a drive connection which runs from a crankshaft to the camshaft. The camshaft has at least one insert part permanently inserted camshaft wherein these two components together form at least one hydraulic medium guide at least in partial regions over its axial length. This design is to create a camshaft adjuster which is in interaction with a camshaft having an insert part so that there is a simple and reliable supply of hydraulic medium to the camshaft adjuster and in particular to its control device.

The cryopreservation of cells and tissue cultures for long term storage of cells, cell constructs or three-dimensional complex tissues assemblies is based on the use of a collagen cell carrier (CCC) having a specific composition and thickness and appropriate mechanical properties which are maintained after thawing. The collagen cell carrier provides a suitable support for the cryopreservation resulting in high survival rates after thawing and providing cells and tissue assemblies already adhered to a mechanically stable and biocompatible support. Frozen collagen carrier-cells assemblies, the frozen artificial cell constructs or three-dimensional complex tissue assemblies obtainable by the method and the use thereof after thawing are also disclosed.

A stable effervescent tablet, granule or powder composition free from excipients that may react with an effervescing organic acid component, comprising, an effective amount of a bisphosphonate bone resorption inhibitor, an effervescing organic acid component, an effervescing base component; wherein said composition is free of polyol binders and tableting lubricants; has a loss on drying of 0.25% (m/m) or less; has a complete disintegration time of no more than 180 seconds when placed in 3 to 8 fluid ounces of water at between 5-20° C.; and said bisphosphonate is incorporated as a micronized particle or by spray drying and is completely solubdised in water within 2 minutes without stirring.
摘要:
A meter bearing with a recess located at the periphery of at least one of the bearing rings. Expansion-measuring strips are disposed in the recess and conducting paths and electronic modules are arranged on a supporting material and evaluate and transmit the output signals of the expansion-measuring strips. The expansion-measuring strips are connected to the electrical conducting paths which extend to the electronic modules. In order to reduce the space required for such a measuring and evaluation system in a meter bearing, the expansion-measuring strips are placed below and/or above the radial plane of the supporting material and of the conductor paths and electronic modules located thereupon.
摘要:
In an internal combustion engine having a coolant circuit which comprises a first coolant line for the cylinder block and a second coolant line for the cylinder head of the engine, with the cylinder head having at least one inlet valve and at least one outlet valve per cylinder, an additional coolant duct provided in the cylinder head in close proximity to the valves is connected to the second coolant line for directly supplying coolant to the area of the cylinder outlet valves.

In a centrifugal oil separator in an internal combustion engine including a centrifuge housing which is placed in a rotationally fixed manner onto a rotating centrifuge shaft, the centrifuge housing is manufactured from plastic and a metal bushing is integrated into the centrifuge housing and is slipped onto the centrifuge shaft.
摘要:
In a method for controlling an inlet valve of an internal combustion engine having at least one cylinder with at least a first inlet valve and a second inlet valve, wherein the closing time of the first inlet valve is adjustable and the first inlet valve is so controlled that, at a first engine speed, the first inlet valve is closed before the closing of the second inlet valve and, at a second engine speed which is higher than the first engine speed, the first inlet valve is closed after the closing time of the second inlet valve.
