Title: Improvement of our living conditions by letting those areas of the countryside which have been paved for traffic grow again
Inventor: PAESELT ARTUR
IPC: E04D11/00
Filed: 1988-01-02
Abstract: Our nature has been robbed, particularly in built-up areas, of cultivatable countryside for huge car parks for supermarkets; these areas are cultivated again by the flat roof which is covered with soil and rests on supports. The flat roof comprises relatively small individual surface areas which fit together closely, excess rainwater is directly channelled away in each case, and ventilation windows are formed by individual grilled surface areas. The cultivation is laid out in the manner of a park and comprises everything from mosses to pines which are as high as a man; a virtually maintenance-free flora which flourishes naturally and withstands the harshest of winters and weeks without rain. Entering by way of steps, visitors come up to see the area and to sit around it. Nothing is being sold here, there is only parkland. All parts are prefabricated in steelworks and can be rapidly erected by the prefabricated-home construction method. Everyone is happy about this innovation and for the steelworker who is kept busy as a result and, above all, that this puts an end to the concrete jungle.
Patent DE-3802298-A1 (DE)
Inventor: MERCER PETER G
IPC: D21F1/02
Filed: 1988-01-27
Abstract: A process and a device are disclosed to improve the homogeneity of the fibre distribution during the mechanical production of a fibrous web from a suspension of fibrous materials, in particular during the production of a paper web. The suspension of fibrous materials is ejected (36) as a jet through an opening formed by lips (31, 32) on a headbox and is conveyed on to screening means. On the screening means the suspension of fibrous materials is prograssively dewatered. In order to control or adjust the output of fibrous materials in the feed direction of the machine and transversely thereto, a gaseous, vapor-like and/or fluid medium is pressed in sheet form, for example as an air carpet, against the suspension of fibrous materials, transversely to its flow, in the area of the through-channel of the headbox, preferably at a point near the lip opening. By controlling the supply of said medium it is possible to adjust the flow of fibrous materials.

Title: Method for automatically measuring surface tension or interfacial tension in order to optimise physical processes at the interfaces
Inventor: RUEHLE DIETER DIPL ING
IPC: G01N13/02
Filed: 1988-03-17
Abstract: The method for measuring surface tension is based on the determination of the wetting angle on a drop (3) which is formed by wetting a solid. For the determination of the wetting angle, a video image of the drop (3) is first generated and the brightness values of the appertaining image pixels are digitilized and stored in a computer (6). The computer (6) then determines the contour of the drop (3) in the vicinity of the three-phase point where liquid, solid surface and atmosphere meet one another. This contour is then approximated analytically by a polynomial and the wetting angle subsequently determined by means of formation of the first derivative of the polynomial at the position of the three-phase point. The appertaining measured value is further processed directly by the computer (6), in order to determine the desired surface tension of a liquid or a solid having polar and non-polar components. <IMAGE>

Title: Process for the preparation and purification of an aqueous phosphorous acid
Inventor: BELTZ KLAUS DR RER NAT
IPC: C01B25/163
Filed: 1988-03-18
Abstract: The present invention relates to a process for recovering an aqueous phosphorous acid from the calcium phosphite sludge from the production of hypophosphite and the purification of the acid of the accompanying heavy metals and arsenic. Phosphorous acid is used as raw material for the synthesis of phosphonates. The process is characterised by the following technical measures, that the secondary calcium phosphite, which is sparingly soluble in water, is converted by treatment with sulphuric acid with precipitation of calcium sulphate into the free phosphorous acid, the precipitated calcium sulphate is separated off from the aqueous phosphorous acid and the heavy metals and arsenic are very largely converted into sparingly soluble compounds by addition of an aqueous solution of alkali metal hexacyanoferrates and an aqueous solution of salts of polysulphanes and separated off from the acid solution.

Patent DE-3825262-A1 (DE)
Title: Circuit arrangement for the dynamic focusing of the electron beam of image pick-up tubes
Inventor: FROEHLICH WALTER DIPL ING
IPC: H04N3/26
Filed: 1988-07-25
Abstract: It is known to supply the focusing electrode (g) of image pick-up tubes (AR) with correction signals for dynamic focusing. Because of the capacitive load on the focusing electrode (g), the amplifier driving the latter must have a low output impedance if the voltage of the focusing electrode is to follow the input voltage of the amplifier. To reduce the power requirement of the amplifier, the latter (V1) has a high output impedance so that it acts as integrator in connection with the capacitive load (C3). To compensate for the integrating effect, a differentiating section (C1, V1) precedes the amplifier. The invention is used in television cameras. <IMAGE>
