Patent DE-3221287-A1 (DE)
Title: Process for eliminating phosphorus compounds from waste water
Inventor: STAEHLER HUBERTUS
IPC: C02F3/12
Filed: 1982-06-05
Abstract: In processes for biological clarification of waste waters, the waste water is passed through an activated-sludge tank to convert organic nitrogen compounds into nitrites and nitrates and, to separate water and sludge, through a secondary clarification tank, from which water and sludge are separately withdrawn. The sludge withdrawal is periodically interrupted. During the interruption, the nitrites and nitrates are degraded by microbes, the oxygen being taken up by the microbes and the nitrogen escaping in the gaseous state from the water. In order also to eliminate the phosphorus compounds from the water, the content of free oxygen in the waste water in the activated-sludge tank is maintained at a value sufficient for nitrification of the organic nitrogen compounds and the withdrawal of sludge is only interrupted for a period of time sufficient for a denitrification of the nitrites and nitrates.

IPC: B60B39/06
Filed: 1982-07-27
Abstract: Arranged on each of the steerable front wheels of a motor vehicle is a spreading nozzle which is connected to the spreading-material container by means of a flexible hose and which brings flowable spreading material in front of the vehicle wheels. The spreading-material container forms at the same time the bumper bar of the vehicle and is located in its place on the vehicle. Each spreading nozzle is assigned a valve. A further valve is located inside the spreading-material container at the outlet to each of the spreading nozzles. The valves can be actuated from the driver's seat. Moreover, the valves of the spreading nozzles are coupled to the brake pedal of the vehicle. If the spreading nozzles are attached additionally or only in front of the rear wheels of the vehicle, the spreading-material container is located between the backrest of the rear seat and a vertical partition wall arranged in the boot space. By means of the laterally outwardly and obliquely downwardly extending bottom surface of the front and rear spreading-material container, the spreading material flows in front of the vehicle wheels as a result of its own weight, without a conveying aid, when the valves are opened.

Patent DE-3233425-A1 (DE)
Title: Matrix printer with a replaceable print head
Inventor: DROGI DIETER
IPC: B41J25/34
Filed: 1982-09-09
Abstract: The requirement for high print quality which approaches that of a typewriter is constantly increasing with matrix printers. For this purpose, mosaic print heads (29) are known with print elements (31) arranged in two column rows, the print elements (31) of the one row being arranged offset with respect to those of the other row. The print elements (31) in the two column rows are actuated with a delay. This delay time has a constant value in known mosaic printers. In mosaic printers with replaceable print heads (29) this is disadvantageous since the spacing tolerance of the dot image elements which is due to manufacturing reasons is too large for high quality print. The invention is based on the object of obtaining print quality which is similar to that of a typewriter each time the mosaic print head (29) is changed by the person operating the machine. This quality is ensured by means of a detection device for detecting the column spacing of the print element rows which automatically sets the delay time of the delay device (39, 41) via a control device. Therefore, the print head change can be performed by any operator and a high print quality is maintained. <IMAGE>

IPC: A23K50/75
Filed: 1984-02-15
Abstract: The invention relates to a feed for chickens and chicks and a process for its production and a process for rearing and keeping chickens with use of the feed. According to the invention it is proposed to use as feed up to 80% compost, in particular 40 to 60% compost, the remaining fraction being composed of conventional cereals and/or manufactured feed. The compost in this case should preferably be obtained from a pile of vegetable wastes having a maximal height of 40 cm, in particular 25 to 30 cm, an amount of 200 g to 1000 g, preferably 500 g, of primary rock meal, in particular basalt meal, being added per M<3> of vegetable wastes. The vegetable wastes should be aerated during the compost formation by regular raking up. When the above described feed is used in feeding, a high resistance to disease and parasites and a decrease in aggressive behaviour combined with increased vitality and activity and improved growth are achieved. In addition, higher rates of fertilisation and hatching are achieved which are maintained over the entire year. Scratching and ejecting feed from the feeding positions cease.
