Title: Formation of humus layers on e.g. rubbish dumps to provide reclaimed and for long-term agricultural use - comprises working compost into surface, applying mineral fertiliser, then sowing plants and subsequently working into surface
IPC: A01B79/02
Filed: 1992-11-30
Abstract: Producing a layer of humus on e.g. rubbish tips, consists of (I) after levelling, a first layer of vegetable matter compost of relatively even strength is applied and (II) working into the surface to a shallow depth using the customary equipment; (III) applying a mineral fertiliser; (IV) sowing with humus-forming and surface-covering plants; (V) breaking-up and working resulting vegetation into surface to more than a shallow depth; (VI) further applying vegetable matter compost and working into surface to a shallow depth; and (VII) sowing agriculturally useful and substrate-specific plants. A shallow depth means a depth of 10 cm or less, and a more than shallow depth means of depth of 15 cm or less. The required compost is pref. produced by growing suitable plants on neighbouring areas which have already been covered with a layer of humus. These plants are harvested, placed in stacks, aerated, after 20 days turned over a first time, and after 40 days turned over for a second time. Earthworms may be added to the compost. Absorptive soil may be placed between the layers of compost, lime may be added, and the compost heap may be constantly moistened. The humus-forming plants may be mixtures of grasses and/or herbs. The substrate-specific plants may be harvested for use, or may be broken up and worked into the surface. The pref. plant is lucerne. Further sowings and applications of fertiliser are used until the required thickness of humus has been formed. Breaking-up of the sowings takes place immediatley before implementation of the subsequent procedure. USE/ADVANTAGE - Used for formation of humus layer on rubbish dumps and other areas which are at risk of erosion and are not suitable for direct sowing with plants, in order to produce reclaimed land which can be used in agriculture. Substrate is effectively covered and the reclaimed land is suitable for long-term use in agriculture.

Title: Prodn. of heat energy using closed circuit reaction driven by solar power
Inventor: HEMMER KLAUS DR ING
IPC: F24S90/00
Filed: 1994-01-02
Abstract: Solar energy is captured and stored in a process to substitute for fossil fuel by the production of a reactant using solar energy, which surrenders adequate heat energy in combination with water. The original reactant, e.g. liquid sodium hydroxide, is recovered in a second subsequent process after combustion.  The novelty is that a reaction cycle is produced which is closed other than for the continual introduction of solar energy. Solar energy added to the closed circuit materials produces a reactant, water and oxygen. Oxygen produced is surrendered to the atmosphere. The reactant and water are combined to yield a by-product and hydrogen. Hydrogen combined with atmospheric oxygen yields usable energy for combustion, while the by-product is split by solar energy back to the original reactants, water and oxygen. No further energy is required other than the solar energy.

Filed: 1994-09-19
Abstract: Horizontal motion vectors are determined by interfield correlation of input video signals S1, S2 whilst first vertical motion vectors are determined by interframe correlation of the input video signals S1, S3. A second vertical motion vector may be determined by interfield correlation; the first vertical motion vector is chosen as the true vertical motion vector unless the second vertical motion vector exceeds a threshold. Initial motion vectors are stored in memory 5. Transition areas between moving and still picture areas may be detected (13, figure 11) and the null vector (V0) used as an initial motion vector in these areas (rather than a vector stored in memory 5). Initial motion vectors for a block may be selected from a plurality of motion vectors previously determined for that block and motion vectors already determined for blocks surrounding that block. <IMAGE>
