Title: Process and apparatus for removing the ammonia and/or nitrate content of waters
Inventor: BITSKEY JOZSEF DR
IPC: C02F9/00
Filed: 1984-03-27
Abstract: The invention relates to a process for removing the ammonia and/or nitrate content of waters (surface waters, subterranean waters, waste waters) and an apparatus for carrying out this process. It is characteristic for the invention that the removal of the ammonia and/or nitrate content is carried out in a biological stage. In the biological reactor packed with granular particles, a culture of lower-order fungi non-pathogenic to humans (for example Aspergillus niger) is established and kept there under aerobic conditions. Before the water to be purified is passed into the reactor, nutrients essential for the fungi are added. This is not necessary when waste water is purified, since the waste water contains sufficient nutrients. The fungi bind the ammonia and/or nitrate content of the water significantly more rapidly than the known biological stages operating with bacteria. The apparatus according to the invention contains, in addition to the biological reactor mentioned, metering devices for chemicals, filters, metering devices for chlorine, a flocculation vessel and an activated charcoal adsorber.

Abstract: The paper machine press section has, in the running direction of the web (W), at least three successive separate press gaps (N1, N2, Np) which essentially drain the web (W) and between which the web (W) is between closed guides. The draining takes place at least in the first press gap (N1) through both surfaces of the web (W), the first gap (N1) being formed between two press rollers (24, 25) having an expediently hollow-profiled surface. In the press section, there is a first cloth (20) which serves as a pick-up cloth to which the web (W) is transferred from the forming wire (10). The press section includes at least one upper cloth (30) and lower cloths (40, 50), those cloths which are the first (20, 40) in the running direction of the web (W) being water-absorbing press cloths which are arranged in such a way that one of these first cloths serves as a press cloth in the first gap (N1) and the other cloth serves as a press cloth both in the first press gap and in the second press gap (N1, N2). Of the cloths (30, 50) which are second in the running direction of the web (W), the upper cloth (30) is a water-absorbing press cloth, and the other, lower cloth serves essentially as a transport cloth (50) or belt which does not absorb water. The web (W) is taken downstream of the third press gap (Np) between closed guides by the transport cloth (50) or belt to the dry end which follows the press section. A so-called long-gap press (100) serves as a third separate pressing location ...

Patent DE-3517339-A1 (DE)
Title: Conveying trough with or without stabilisation of the temperature of the bulk material
Inventor: REIMER FRANZ
IPC: B65G27/04
Filed: 1985-05-14
Abstract: The method and the device permits conveying with the possibility of simultaneously stabilising the temperature of bulk materials. The arrangement permits cooling or heating or both alternately. This effect is achieved by using a multi-track floor, with or without a throughflow of temperature equalising agent, as a trough floor. The multi-track floor may have the structure of a lamellar heating body or may comprise one or more lamellar heating bodies directly. A permporous hollow body, for example a pipe or a flexible tube, through which conveying gas or temperature-stabilised gas is guided, can be inserted into the individual tracks for fluidisation and/or temperature stabilisation. Connection of an oscillator optimises conveying and temperature stabilisation.

Title: Ignition lock cover for motor vehicles
IPC: B60R25/04
Filed: 1985-06-28
Abstract: A device is described which makes it possible to attract a motor vehicle driver's attention to a particular piece of information before he/she actuates the ignition and which can also be retrofitted to almost all current motor vehicles, without incurring a large outlay. This device is an ignition lock cover, which covers the keyhole when the ignition key has been pulled out and must be raised before the ignition key is inserted, thereby attracting the attention of the driver. The ignition lock cover essentially comprises a covering part and a fastening element, which is connected to the covering part by means of a flexible connecting strip. In order to permit rapid and easy assembly, the fastening part may be an adhesive strip which, like the connecting strip, is made of a flexible plastic and is also stuck to the covering part. The said ignition lock cover is, for example, a simple means for reminding the driver of a motor vehicle before he/she actuates the ignition that he/she should put on his/her safety belt.
Patent DE-3537141-A1 (DE)
Title: Screw-screwdriver system with conical groove
Inventor: SIEBKER THOMAS
IPC: B25G1/00
Filed: 1985-10-18
Abstract: The invention relates, in principle, to all applications of screws. In practice, screws are often so blocked that they are very difficult to unscrew (e.g. bonding to paint, rusting through, etc.). The slipping-off of the tool is an additional problem. The problem was solved by widening the screw-head groove inwards and, to match this, conically widening the end of the screwdriver. Slipping back is prevented. Additional blocking bulges also prevent lateral jumping out. Both screws and screwdrivers can be used with conventional screwdrivers and screws.
Patent DE-3539161-A1 (DE)
Title: Convection heat sink
Inventor: DAUB DETLEF
IPC: H01L23/467
Filed: 1985-11-05
Abstract: A convection heat sink to receive electrical, preferably electronic, components, and to dissipate the heat generated in them, is to be formed so that, on the one hand, it permits dissipation of high heat output with small dimensions, and, on the other hand, at the same time, various sizes with various heat emission capabilities can be manufactured easily and using relatively few tools. To achieve this aim, a flat supporting plate to receive the electrical components to be cooled, or legs joined to the plate, are connected to vertical cooling ribs, which enclose continuous vertical hollow spaces like honeycombs, and which, expediently, consist of sections which are connected to each other as well as to the supporting plate or the legs, and each extend only over part-sections and/or part of the length of the base area of the honeycomb construction, so that, on the one hand, the groups of vertical cooling ribs can easily be assembled from elements in various sizes, and, on the other hand, the vertical cooling ribs can cause intense heat emission by means of the chimney effect of the heated rising air.

Title: Automatic transmission system for vehicles
Inventor: KURIHARA KAZUMASA
IPC: B60W10/10
Filed: 1985-11-08
Abstract: An automatic transmission system for a motor vehicle, in which the gear changes are performed according to electrical signals, has signal generators, which generate a first signal indicating the speed of the vehicle and a second signal, which indicates the magnitude of the operation of an accelerator pedal. A third signal which indicates the speed when the accelerator pedal is operated, is generated on the basis of the first and second signals and the gear change is controlled according to the first to third signals. The system thereby responds to the driver's intention through operation of the accelerator pedal. Consequently it is possible to shift the transmission into the optimum position according to the operation of the accelerator pedal, in order to ensure optimum vehicle handling.
Patent DE-3542306-A1 (DE)
Title: Double detector
Inventor: HARJA CONSTANTIN DIPL ING
IPC: H01J47/02
Filed: 1985-11-29
Abstract: A double detector, which consists of two gas ionization chambers (3, 5) arranged one behind the other in the radiation direction (1), is provided for separate and simultaneous measurement of alpha radiation and beta radiation which are jointly emitted by a radiation source. The chamber (3) facing the radiation source is operated for measuring the alpha activity in the ionization region. The chamber (5) facing away from the radiation source is operated for measuring the beta activity in the proportional region. Suitable dimensioning of the inlet window (11), of the gas volume of the alpha chamber (3), and of the separating window (9) ensures that essentially all the alpha radiation entering the double detector is absorbed in the alpha chamber (3). The beta activity, which is measured by means of the beta chamber (5), is thus not corrupted by alpha radiation. <IMAGE>

Title: Hang glider
Inventor: LORSBACH RALF
IPC: B64C31/028
Filed: 1986-03-14
Abstract: The hang glider which is described in the main patent ... (Patent Application P 3516998.2) and has an adjustable wing area and profile displacement is considerably improved by this invention with respect to the following items. Side rods, which are split in two and are jointed in the centre, create a double-trapezoidal wing geometry in the case of which the wing warping in fact occurs only in the outer wing section. A mechanical control system, which consists of cable runs and a specially designed pilot suspension means, converts the control movements of the pilot in the lateral direction about the vertical and in the longitudinal direction into a wing area and profile displacement which is asymmetric with respect to the longitudinal axis, into an asymmetric warping angle displacement and into a symmetric warping angle displacement of the hang glider. Highly curved profiles can also be clamped on as a result of a bent shape of the front and rear struts and of the keel tube. Bracing, which consists of one or two tubes, of the kingpost (uprights) and control bar (bottom bar) replaces the conventional cable bracing of the same to the keel tube.
