Patent DE-3050807-A1 (DE)
Title: Automatic venetian blind controlled and powered by solar cells - has housing accommodating motor and battery and operates according to outdoor conditions for energy saving
Inventor: GOETZBERGER ADOLF PROF DR
IPC: E06B9/70
Filed: 1980-12-18
Abstract: The blinds are opened when the solar cells detect sunlight so that the hot house effect can be exploited. Otherwise they are closed to use their heat insulating effect. They are powered by an electric motor with a built-in power supply, the battery being charged from the solar cells fixed to the case of the roller blind drive mechanism. The solar cells trigger the raising and lowering of the blind by having their output measured, e.g. if the output is low it is dusk and the blind is dropped. If this system could be confused by, e.g. street lights, an integrated quartz timer can take over this function.

Title: Process for producing hydraulic and eminently hydraulic binders
Inventor: WISSING WILHELM
IPC: C04B18/12
Filed: 1981-01-17
Abstract: The mechanical mining of hard coal at the same time necessitates the mining of the intrusive rocks in which the coal strata are embedded. The weight of the quantities of rock, usually occurring as shale, is often higher than the weight of the minable coal. This causes huge tipping problems. These rock tips - known as refuse tips - are a huge environmental problem because they are water soluble. The shale rock - known as refuse - is a utilisable natural material from which useful materials and raw materials can be obtained. This patent application relates to processes for producing hydraulic and eminently hydraulic binders from washed-out and picked-out refuse. The clinkers produced as intermediate product are ground to form cements. The clinkers themselves, unground, are a good aggregate material and road building material.

Patent DE-3113299-A1 (DE)
Title: Process for the surface treatment of workpieces with organic substances
Inventor: JENNERT HEINZ
IPC: C09D9/00
Filed: 1981-04-02
Abstract: With reference to an example of paint stripping gratings and other coated wet and stoved article supports or workpieces, the following was described: paint-contaminated workpieces are treated in a cold paint-stripping bath based on methylene chloride. Depending on the particular application, the active bath is adjusted to be acidic or alkaline. After completion of the exposure time of from approximately 1 hour to 24 hours, the parts are transferred to an aqueous bath at approximately 50 DEG C for 5-8 min. The boiling point of the organic medium, methylene chloride, is 42 DEG C, and distillation into the air above the vessel therefore takes place. The air loaded with organic solvent, in this example methylene chloride, is extracted via an active carbon system. The methylene chloride is absorbed on the carbon, the clean air with a concentration of methylene chloride of < 100 mg/m<3> can be discharged by a roof stack.

Title: Optical coating system on a curved surface and method for producing the same
Inventor: BOLLA ISTVAN DR
IPC: H01K1/32
Filed: 1981-07-03
Abstract: The invention relates to a coating system prepared on a curved surface made from dielectrics, and to a method for producing the coating system. The essence of the invention is that the coating system contains coatings of an optical thickness which increases/decreases with the increasing/decreasing angle of incidence of the light beam. In accordance with the method, when the coatings are being produced the pressure of the diffusing gas and the position of an object having the curved surface are set such that the spectral distribution of the light retroreflected by the individual surface elements is the same or approximately the same. The coating system according to the invention forms on the curved surfaces, in particular on belly-shaped objects, a cover which ensures the spectral distribution characterised by the transmission and reflection curves of the cold mirrors. The coating system can also be produced effectively and economically in long series.
Patent DE-3128474-A1 (DE)
Title: Process for countercurrent washing of finely divided crude terephthalic acid
Inventor: VAILLANCOURT JOSEPH ANTHONY
IPC: C07C51/47
Filed: 1981-07-18
Abstract: A process is disclosed for countercurrent washing of finely divided crude terephthalic acid using a washing liquid of substantially different density in a washing tower. In order to avoid channel formation and back-mixing of the liquid in the tower, and to intensify the washing or scrubbing of the particles, the column is subdivided in the transverse direction by at least one intermediate floor having therein a multiplicity of specially dimensioned holes which affect particle penetrability. In addition, the process comprises a continuous and hydraulic sequence of steps, in which, in one step, a deposition (or ascension) takes place, under the influence of gravity, for a sufficiently long period of time, so that the terephthalic acid particles collect and agglomerate, and can form a non-fluidised bed in the vicinity of the intermediate floor; subsequently, a step takes place involving the transport of the terephthalic acid particles with the aid of a unidirectional liquid stream, the speed and duration of which is sufficient to fluidise the bed and to transport the fluidised particles of terephthalic acid through the holes of the intermediate floor.
