摘要： A dental furnace for heat treatment of dental materials and dental components, particularly for firing these at temperatures over 100.degree. C. comprises an insulated furnace space which can be closed off by a door. The furnace space has a housing which is suspended in an inner housing of metal; the inner housing is supported by a multi-part outer housing, and the door is pivotably fastened on the inner housing. In order to satisfy the requirements of firing at up to 400.degree. C., and to achieve a simple, cost-effective, and light construction, the furnance of the invention has a plastic outer housing, connected by securing elements to the inner housing; the plastic elements have a shell-shaped configuration, so that they define a hollow space surrounding the inner housing, at least adjacent the sidewalls of the outer housing. The hollow space serves as an insulator, minimizing the need for other insulating materials.

摘要： A hand-operated polymerizer for the polymerization of synthetic materials, such as dental plastics. The polymerizer has a housing in which a light source and a fan are disposed, and which includes a light-emitting opening for emitting the light generated by the light source. The housing contains openings for permitting cooling air to enter the housing and for allowing heated air to exit the housing. In order to prevent the operator of the polymerizer from being impaired by heated air when operating the polymerizer, at least one air-conducting member is provided, wherein the position of the air-conducting member is changeable relative to the housing.

摘要： Polymerization devices having an irradiation space in an irradiation chamber, the space being accessible via at least one pivotable or displaceable wall, and having a light conductor and a radiation source unit, wherein the light conductor feeds the radiation from the radiation source into the irradiation space of the irradiation chamber and forms a releasable connection between the irradiation chamber and the radiation source unit, are known. To create a polymerization device that makes it possible to operate an irradiation chamber for curing plastic dental parts by means of a hand-held polymerization unit, with the capability of easy conversion from a hand-held polymerization unit to a stationary polymerization device, the radiation source unit is a hand-held polymerization unit, which is retained by its housing part on a first support, disposed on a support plate of a support frame; the light conductor is guided in a second support of the support plate; and the irradiation chamber is supported on a part of the support frame.

摘要： A driving circuit for a low-pressure discharge lamp, particularly a compact fluorescent lamp, features a heating transformer with two separate secondary windings, which are respectively permanently connected to the lamp electrodes, and furnish them with pre-heating current. Parallel to the primary winding of the transformer, there is connected a series circuit of an operating switch, a ballast inductor, and the discharge path formed between the lamp electrodes. The electrodes are connected to each other via a starter connected in parallel to the discharge path.

摘要： The present invention is an improvement upon a known apparatus for polymerization of a body from dental plastic material by irradiation of the body with radiation of a selected wave length in the range between about 350 nm and about 550 nm. To achieve a desired degree of polymerziation of the dental plastic, a specific amount of radiation must be applied to the body. In order to achieve reproducible irradiation results in spite of fluctuations in supply voltage, alterations in lamp characteristics, burn out of one or more lamps, shifting of spectral outputs, replacement of defective or superannuated lamps, soiling of lamps and reflector surfaces and/or changes of operating temperatures in the irradiation area, a supplemental detection system in provided. Upon beginning of irradiation, a photocell measures a percentage component of the radiation within the selected wave length range from each irradiation source, generates an electrical signal therefrom and the electrical signal is integrated and compared to a predetermined value corresponding to the desired degree of polymerization. When the predetermined value is reached, the irradiation is interrupted.
