The present invention relates to a freewheel comprising an outer ring, an inner ring, and at least one clamping element which is between the outer ring and the inner ring, which is moveable from a clamping position into a release position along a race on the outer ring in a first circumferential direction relative to the outer ring, wherein the race has a clamping section, and a release section following the clamping section in the first circumferential direction on which the clamping element is supportable. A first tangent through at least one support point on the clamping section defines a first inner angle, which is greater than 180&#xb0;, with a second tangent through at least one support point on the release section. In addition, the present invention relates to a freewheel arrangement for a motor vehicle comprising such a freewheel.

Freewheel and freewheel arrangement comprising such a freewheel

A starter freewheel is provided. The starter freewheel has a first race, a second race, a wedging gap formed between the first and second races, at least one wedging element arranged in the wedging gap, and at least one further component. The further component is in rotary drive connection with one of the races. The component is formed by at least two sheet-metal parts connected to one another in sandwich-fashion. A freewheel arrangement having a starter freewheel of this kind is also provided.

Starter freewheel and freewheel arrangement having a starter freewheel of this kind

Disclosed is a freewheel () comprising a first race (), a second race (), a clamping gap () designed between the first and second race (), at least one clamping element () in the clamping gap (), and biasing feature () for biasing the clamping element () into a clamping position within the clamping gap (), wherein the biasing feature () have an accordion spring (), which is supported directly or indirectly on the first race () and which comprises corrugation peaks () lying radially outward, corrugation troughs () lying radially inward, and a support leg () for direct or indirect support on the clamping element (). In addition, disclosed is a freewheel arrangement () comprising such a freewheel ().

The present invention relates to a method of enhancing the latent hydraulic and/or pozzolanic reactivity of materials, especially of waste and by-products, comprising the steps: providing a starting material containing sources for CaO and at least one of SiOand AIOmixing the starting material with water at a water/solids ratio from 0.1 to 100 hydrothermal treating of the starting material mixed with water in an autoclave at a temperature of 100 to 300&#xb0; C. and a residence time from 0.1 to 24 hours to provide an autoclaved product suitable as supplementary cementitious material.

Method of enhancing the latent hydraulic and/or pozzolanic reactivity of materials

The present invention relates to a method for producing a binder comprising the following steps:

Method for producing magnesium silicate-belite-calcium aluminate cement

A freewheel () having a first running ring (), a second running ring (), a clamping gap () formed between the first and second running rings (), and at least one clamping element () in the clamping gap (), the clamping gap () being assigned a side wall () on which the at least one clamping element () can be or is supported. A side () of the clamping element () which faces toward the side wall () and/or that side () of the side wall () which faces toward the clamping element () is provided with a friction-reducing, wear-reducing and/or corrosion-reducing coating () or surface treatment.

Freewheel and freewheel arrangement

A freewheel arrangement having a freewheel, which comprises an inner ring, an outer ring rotatable in a first direction of rotation relative to the inner ring, and clamping elements between the inner ring and the outer ring, which prevent a rotation of the outer ring relative to the inner ring in a second direction of rotation. The outer ring and the inner ring and the clamping elements may be formed as a stamped sheet metal part.

Freewheel arrangement

The present invention relates to the use of a belite calcium aluminate obtainable in a method comprising the following steps:

Belite-calcium aluminate as an additive

The present invention relates to binders based on latently hydraulic and/or pozzolanic materials that are activated by an addition of ternesite (CS$).

Ternesite used as an activator for latent-hydraulic and pozzolanic materials

The present invention relates to a method for accelerating the hardening of hydraulic or latent hydraulic binders, wherein ternesite and an aluminum component are added to the binder, and relates to an additive that increasing early strength for hydraulic or latent hydraulic binders that contain ternesite and a non-hydraulically reactive aluminum component, and relates to the use of an additive comprising ternesite and an aluminum component for the purpose of accelerating the hardening of hydraulic or latent hydraulic binders.

Method and additive for increasing early strength

The present invention relates to a ternesite calcium sulfoaluminate clinker as well as a ternesite clinker containing 20 to 100% by weight of CS$ and less than 15% by weight of CA$, as well as the use of ternesite as an additive to calcium sulfoaluminate (ferrite) (belite) (CSA(F)(B)) clinker, calcium sulfoaluminate (ferrite) (belite) cement, and calcium sulfoaluminate (ferrite) (belite) binder containing 10 to 90% by weight of CSA(F)(B) and 90 to 10% by weight of ternesite.

Calcium sulfoaluminate cement with ternesite

The present invention relates to the production of ternesite clinkers containing 20 to 95% by weight CS$ and less than 15% by weight CA$, and to the use of ternesite as an additive to hydraulic and/or latent hydraulic and/or pozzolanic materials.

Method for producing ternesite

The present invention relates to the production of a ternesite-belite-calcium sulfoaluminate (ferrite) clinker. The invention also relates to the use of alternative raw materials for clinker production, for example raw materials based on industrial byproducts, including those of low quality, such as lump slag and ash having a low glass content and/or a high free lime content and/or a high content of crystalline high-temperature phases, as well as naturally occurring rocks and rock glasses of comparative chemical composition.

Method for producing ternesite-belite calcium sulfoaluminate clinker

The present invention relates to the production of ternesite clinkers containing 20 to 100% by weight CS$ and less than 15% by weight CA$, and to the use of ternesite as an additive to Portland cement or Portland composite cement, and to a binder containing 20 to 95% by weight Portland cement (clinker) and 80 to 5% by weight ternesite (clinker).
