Title: Method for producing load-bearing lawns
Inventor: DIENER DIETRICH
IPC: E01C13/08
Filed: 1981-02-28
Abstract: The invention relates to a method for producing load-bearing lawns on a subsoil which is levelled by means of rough grading and into which a slot drainage with vertical drainage slots is incorporated, the slots reaching down into a water-diverting zone, in which method a lawn support layer enriched with aggregates down to a predetermined depth is placed on the levelled subsoil, and vertical dewatering slots are incorporated in this lawn support layer and reach down into the subsoil and extend transversely to the drainage slots. In the production of the lawn, in order to prevent an interlocking between the drainage slots and dewatering slots, on the one hand, and between the subsoil and the lawn support layer, on the other hand, which interlocking leads to formation of silt, and in order to improve the growth conditions for the lawn, the necessary work steps according to the invention area carried out as follows: first, the lawn support layer is placed on the levelled subsoil; water-storing aggregates are then placed on the lawn support layer, which aggregates begin to lead-off water when a predetermined moisture content is reached; the applied aggregates are worked into the lawn support layer down to the predetermined depth, which is smaller than the thickness of the lawn support layer, and only then are the vertical dewatering slots incorporated and, at the same time, filled with filler material; and, finally, fertilisers are applied to the lawn support layer thus treated and are worked into the lawn support layer together with the seed.

Patent DE-3125029-A1 (DE)
Title: Non-return valve
Inventor: STRATE WOLF-PETER
IPC: F16K37/00
Filed: 1981-06-23
Abstract: Non-return valves (backflow preventers) are used in pumping stations to prevent the pumped water from flowing back when the pump is switched off. The closing plate of the non-return valve is subject to the action of a force which accelerates the closure process and counteracts that of opening. Hitherto, the closing plate has been borne by a spindle which is mounted in a housing and at one end of which is attached, via a lever arm, a weight which brings about the force on the closing plate. In order to reduce the bearing load caused by the weight and the heavy non-return valve, the closing plate is attached to the housing via separate, unsupported suspension on the housing. The force acting on the closing plate is produced by a damping spring which engages between the housing and a spindle on which is secured a lever which, due to the spring force, presses against the closing plate. On that end of the said spindle which is outside the housing there is a pointer which indicates the position of the closing plate.
Patent DE-3134649-A1 (DE)
Title: Stereoscopic television system
Inventor: PUESCHEL DIETMAR
IPC: H04N13/00
Filed: 1981-08-28
Abstract: The invention relates to a stereoscopic image system in which television engineering is used for the first time. The invention is based on the object of creating a stereoscopic television system which provides for high-quality stereoscopy with low technical expenditure and using conventional apparatus. This object is achieved by the fact that the images recorded by two black/white television cameras standing at eye distance from one another are converted, via only two channels of a colour encoder, into signals of a two-colour mixed image which is supplied to a conventional colour television receiver, the image of which must be viewed through spectacles, the glasses of which are correspondingly coloured. Thus, only two conventional black/white television cameras and one colour encoder are needed for the stereoscopic television system according to the invention, which encoder, however, only acts on two colour channels. The signals formed in the colour encoder for a two-colour mixed image are then optionally recorded via a colour television receiver or a commercially available video recorder and viewed through conventional two-colour stereo spectacles. The system thus provides a black/white image which is sensed to be three-dimensional. The hardware expenditure has thus become minimal and the stereoscopic image reproduction has become easy. <IMAGE>

Patent DE-3202062-A1 (DE)
Title: Chopping block
Inventor: KANNENBERG DIETER
IPC: B27L7/08
Filed: 1982-01-23
Abstract: The wood-catching basket is a basket produced from sheet steel and strong wire mesh welded thereto, which basket is screwed on 15 cm from the top edge of a chopping block. Its technical function resides in the catching of wood chips flying away from the chopping block during the chopping of firewood. The split wooden chips collect on the inner edge of the wood catching basket. In an upright position, the split wood can effortlessly be transferred from the catching basket into a wheelbarrow or container. Also, it is no longer necessary to bend again in order to produce those wood chips which have to be chopped even smaller (kindling). Spectators standing around the chopping block can no longer be injured, during wood cutting, by wood chips flying away sideways and forwards, since the wood-catching basket prevents this. The wood-catching basket can be used domestically or in forestry and agriculture. <IMAGE>

Title: Structural element of solid-wood parts connected to one another
Inventor: MELANG HANS-GEORG
IPC: E04C3/16
Filed: 1982-09-02
Abstract: The structural element is composed of four parallel corner slats (1) arranged at the corners of a square and having the same square cross-section and the same length and also of centre slats (2, 3) of the same cross-section which at all four sides in each case connect the two corner slats (1) to one another while maintaining a flat outer surface. The centre slats start from the planes of the end faces of the corner slats (1) and contain a number of intermediate slats (3) of the same length which are arranged at a mutual distance from one another in accordance with the single edge length of the slats. Corner slats (1) and centre slats (2, 3) are connected to one another by pressure gluing. Rectangular bodies or bodies with square cross-sections can be assembled from several structural elements of the same size according to the same scheme as this. Characteristic of the basic structural element and the bodies which can be made from it are the continuous hollow spaces running in the longitudinal axis and the hollow spaces perpendicular thereto, the distances of which from one another are identical. These openings offer various possibilities for accommodating further construction elements, such as square slats or the like. The basic structural element and the bodies which can be assembled from it are especially suitable for wooden constructions, for furniture making, for interior finishing and for training and toy construction kits. The saving in unhewn timber compared with a corresponding solid body is about 26% in the basic structural element. <IMAGE>
