摘要:
A dental material, a dental mixture or a dental multi-component system for making the material of or core for a temporary superstructure for a dental implant by polymerization hardening, consisting of one, two or a plurality of polymerizable (meth)acrylates, and optionally further constituents. The dental material, the dental mixture or the multi-component system is hardenable to a product, and the maximum compressive modulus is 420 MPa, and is used in therapeutic treatments for accelerating the osseointegration of dental implants, in particular according to the method of progressive bone loading. Also described are temporary superstructures and cores themselves, and a temporary dental prosthesis, a kit for making a plurality of temporary superstructures for a dental implant or a plurality of cores for temporary superstructures for a dental implant. A corresponding method of preparing a temporary superstructure or a core is also described.

Disclosed is a moisture-curing coating composition based on aprotic solvents comprising a binder with a polyacrylate or polymethacrylate obtained using monomer (I) and a phosphorous- and nitrogen-containing catalyst. Also disclosed is a method of producing a multicoat finish using these coating compositions and also to the use of this method to coat interior or exterior bodywork components or to coat components for shipbuilding and aircraft construction or to coat components for household and electrical appliances or to coat plastics moldings or films.
摘要:
An application apparatus is configured for application of a coating agent onto a component part, for example, for application of a sealing agent onto a body component. The application apparatus may include an elongated part, that is rotatable about its longitudinal axis and has a nozzle head with at least one nozzle to discharge the coating agent, and one valve unit to control the supply of the coating agent to the at least one nozzle. In a disclosed embodiment, the valve unit is formed outside the nozzle head and arranged at least in sections along the elongated part in a direction of the nozzle head.

An electric drive for a parking brake is disclosed, the brake having a rotationally driven screw nut which is in engagement with two spindles which are aligned with one another, have threads running in opposite directions, and which are fixed in the rotational direction, can be moved in a translatory fashion and are each provided with a cable holder for connecting to brake elements. Here, one of the two spindles is a hollow spindle whose internal diameter is greater than the external diameter of the other spindle so that when the screw nut rotates, the spindle on one side can be retracted in a telescopic fashion into the hollow spindle on the other side.

A door arrester for a door of a motor vehicle includes a holder housing including a passage opening for a retaining bar, the holder housing including a first supporting housing part. The first supporting housing part includes injection-molded plastic and a fastening portion for fixing the holder housing onto a part of the motor vehicle. A swinging element and a spring element are provided. The swinging element is pivotable relative to the passage opening toward the retaining bar. The spring element acts upon the swinging element. The first housing part includes a bearing for receiving the swinging element.

A door check is provided comprising a housing (2) that can be fixed to a door or door frame and is provided with a first housing half (3) and a second housing half (4) which can be connected to each other, and a stay bar (24) that penetrates an opening (23) within the housing (2) and is pivotally mounted on the door frame or door, the housing (2) and the stay bar (24) not being fixed to/mounted on the same part. The first housing half (3) and the second housing half (4) respectively delimit only one section of the circumference of the opening (23). In order to create a door check that allows reliable and secure retaining and can be produced at low cost, a braking member (13) which is biased in the direction of the stay bar (24) by means of a spring element (20) is disposed in at least one of the two housing halves (3, 4).
摘要:
The invention relates to a method of producing color pastes, in which a component comprising colorant particles is dispersed in a binder. In the method of the invention the dispersing operation is controlled by beaming excitational light of a defined wavelength range into a mixture of the component comprising colorant particles and the binder, detecting the light transmitted, reflected and/or scattered by the mixture and determining a sample spectrum, evaluating the sample spectrum and hence determining parameters of the color paste, and monitoring changes in the sample spectrum over time and terminating the dispersing operation when predetermined target parameters are attained.
