Abstract: A smoke alarm has a housing with a heating device for heating walls of the housing to a temperature above the dew point. The heating device has at least one heating light emitting diode (LED). The heating LED has an opening angle for the emission of light, which opening angle leads to an irradiated area of the housing.

Abstract: A plug connector for connecting to an electric connection of a fuel injector of an internal combustion engine can comprise a rail extending in a longitudinal direction and at least one insulating element arranged in a linearly movable manner in the longitudinal direction relative to the rail, wherein the at least one insulating element protrudes out of the rail in a transverse direction. In some embodiments, the at least one insulating element comprises means for electrically connecting to the electric connection of the fuel injector in an oil-tight and releasable manner on a side facing away from the rail in the transverse direction. In some embodiments, the rail comprises a guide extending in the longitudinal direction configured to guide the at least one insulating element relative to the rail in the longitudinal direction and hold the same in a formfitting manner in the transverse direction relative to the rail.

Abstract: A portable solar-thermal device produces fresh water from sewage water or salt water. The device has a closed fluid circuit made of connected pipe or hose elements with a sewage water supply and a fresh water runoff. The fluid circuit has a tilted heating section essentially aligned normally to the sun irradiation for heating and vaporization of the sewage water. Connected to this is an essentially vertically aligned condensation section for condensation of the fresh water and heating of the sewage water. A storage section is designed as base area for the condensed fresh water. The heating section of the fluid circuit has a solar collector for concentration of the thermal energy of sun irradiation on a vaporization area inside the heating section.

Abstract: The invention concerns a portable solar-thermal device (1) for the production of fresh water from sewage water or salt water. The device is characterised in that it has a closed fluid circuit (2) made of connected pipe or hose elements with a sewage water supply (3) and a fresh water runoff (4) with the fluid circuit (2) having a tilted heating section (5) essentially aligned normally to the sun irradiation (S) for heating and vaporisation of the sewage water. Connected to this is an essentially vertically aligned condensation section (6) for condensation of the fresh water and heating of the sewage water, and a storage section (7) designed as base area for the condensed fresh water. The heating section (5) of the fluid circuit (2) is characterised by a solar collector (10) for concentration of the thermal energy of sun irradiation (S) on a vaporisation area inside the heating section (5).

Abstract: A building component having a core of recycled material is manufactured according to a method having the following steps: cutting small waste; mixing the small waste particles with a resin; supplying the mixture of small waste particles and resin to a sleeve of set plate material, wherein a hardening agent is added; allowing the mixture in the sleeve to cure; positioning the entirety of the cured mixture and the sleeve in a closed vacuum mould in which set plate material is arranged; filling the mould with a filler; allowing the material in the mould to cure; and releasing the building component thus obtained from the mould. The building component thus obtained has many advantages. In particular, this component is indestructible, durable, strong and lightweight. Moreover, application thereof contributes to a reduction of the mountain of waste and an increased safety.
