Title: Fire-resistant wall element which reduces the passage of heat and is intended in particular as an insert for a fire-retardant door, process for the production thereof and fire-retardant door equipped therewith
Inventor: TIESLER HARTMUT DIPL CHEM
IPC: B32B19/04
Filed: 1985-03-26
Abstract: A fire-resistant wall element, for instance as an insert for fire-retardant doors, for example as composite panel, is obtained by combining at least one mineral-fibre insulating layer (16) with at least one fire-protection zone (17) consisting of granular, bound, carbonate-containing rock such as dolomite or limestone. Possible inorganic binders are, in particular, a non-alkaline hydraulic binder such as magnesium oxychloride or magnesium oxysulphate, or a thermoplastic binder such as an aqueous melt of aluminium sulphate. In the event of fire, a plurality of highly endothermic reactions take place at high temperature, giving, on balance, a very high negative heat of reaction. Remaining after the corresponding conversions and reactions are predominantly fireproof oxides, such as magnesia or quicklime; carbon dioxide is the only gas to escape. Even with a low overall thickness, a wall element of this type satisfies the requirements for fire-resistance grading F90 in accordance with DIN 4102, Part 5. <IMAGE>

Title: Photographic still camera and films cassette therefor
Inventor: STEMME OTTO DR
IPC: G03B17/22
Filed: 1985-04-23
Abstract: In a photographic still camera having two chambers, sealed against the incidence of light in the operating state, for a film cassette having an unexposed film part located on a supply spool, and for a film cassette having an exposed film part and having a cutting device for severing the exposed film part from the unexposed film part, it is proposed to seal off from one another with respect to the incidence of light the two chambers containing the cassettes and to provide locked covers which can be operated separately from one another. This eases the extraction of the exposed segments in a way that saves film. In a development of the invention, special flat cassettes are proposed for the exposed film parts, which are preferably curved in the shape of a U and because of their design can easily be despatched by mail and processed and can be used advantageously with a large supply of film, particularly when the camera is designed as a disposable camera. <IMAGE>
