Patent DE-3617849-A1 (DE)
Title: Breathing air purification apparatus with gentle electrical separation for motor vehicles
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H3/06
Filed: 1986-05-27
Abstract: The invention relates to an air purification apparatus for motor vehicles. The purpose of such an apparatus is to purify the breathing air for motor vehicle occupants from pollutants from car exhausts, solvents of components in motor vehicle manufacture, petrol and oil vapours and residues caused by smoking. In order to carry this out, a multiplicity of purification apparatuses have become known which operate by the most diverse principles. However, all of these have in common the fact that, apart from the advantageous effects doubtless present, they are also burdened with disadvantages. In order to eliminate these disadvantages, according to the invention it is proposed that, apart from introducing chemisorption filter layers, a negative ion generator is connected upstream and a permanently electrically acting dust filter is connected downstream of the chemisorption filter. In this manner, a significantly improved very fine dust separation is achieved and, moreover, the separation of gaseous pollutants is improved. Furthermore, the gentle electrical separation avoids positive ionisation.

Patent DE-3629206-A1 (DE)
Title: Method for transmitting a bit sequence by coded octonary phase-shift keying of a carrier oscillation
Inventor: BERTELSMEIER MANFRED DR ING
IPC: H04L27/18
Filed: 1986-08-28
Abstract: A novel system using coded octonary phase-shift keying is particularly suitable as replacement for existing 4PSK systems. Before the modulation, 4 bits are in each case jointly recoded by convolution coders with 4 to 32 internal states into code words of 5 bits. In dependence on these 5 bits, two successive phase-shift-keyed symbols are in each case generated in a combined modulation step, one of which symbols originates from a set of 8 phases and the other one of which originates from a set of only 4 phases. A sequence generated in this manner contains symbols of a 4PSK, and the carrier oscillation required for coherent demodulation can be recovered with almost the same noise immunity as in conventional 4PSK. The redundancy contained in the recoding allows frequencies to be formed which have an increased Euclidean distance compared with 4PSK and which can be decoded again with the aid of a Viterbi receiver. Compared with 4PSK, the required signal/noise ratio is reduced by about 3 to 4.1 dB (Figure 2). <IMAGE>

Patent DE-3709244-A1 (DE)
Title: Non-return air valve for motor vehicles
Inventor: PRIEN MANFRED
IPC: B60H1/24
Filed: 1987-03-20
Abstract: The closure flap, consisting of a flexible and low specific-weight material, of the non-return air valve is mounted in a suspended manner, bears by virtue of its inherent weight against an oblique grille in the housing of the non-return air valve and, in the event of airflow, moves opposite to the outflow direction into the closed position. In the event of a high rate of the ventilation flow, the flap generates fluttering noises which are annoying in the passenger compartment of the motor vehicle. To prevent the fluttering noises, a plurality of downwardly projecting hook-like webs are mounted above the rectangular closure flap in the movement range thereof such that, at the vertical position at which the fluttering begins, the flap contacts the free end of at least one web and, with increasing air velocity, buckles in the lower edge region, conforms to the webs and is held in angle form.

Title: Glass roof-tiles which act as solar-cells - produced by plastic deformation of float glass material
Inventor: KIRSCHNING HANS JOACHIM DIPL P
IPC: H01L31/048
Filed: 1987-05-09
Abstract: The solar cell substrate is light-transmitting and serves at the same time as a roofing tile. It is formed by stamping from a flat sheet of glass and subsequent plastic deformation at a high temp. The process can form several tiles at the same time. USE/ADVANTAGE - The method takes advantage of the extensive automation already used in float-glass mfr. and adds stages which can also easily be automated. The solar cell can easily be formed or attached to the underside of the tile. This makes the tiles cheaper and gives better control over form and properties. The capital costs associated with the production can be distributed over a range of products which can be made from the float-glass e.g. window glass for buildings and automobiles.

Title: System for using the radiation incident on structural members (rooves, walls, paths and other metalled (paved) surfaces)
Inventor: BRAUNEISEN HEINRICH DIPL ING
IPC: H02S99/00
Filed: 1988-01-16
Abstract: System for using the radiation, especially solar radiation, incident on structural members (rooves, walls, paths and other metalled (paved) surfaces). The acquisition and conversion of the radiation into heat and/or electrical energy is performed by light-collecting and energy-converting materials (solar cells, absorbers, fluorescence collectors) which are accommodated - in a freely selected way - in energy-converting cells, specifically in such a way that they can be exchanged without intervening in the structure of the energy-converting cells if this becomes necessary due to a reduction in efficiency or the like. The structural member forms the support for the energy-converting cells. The cover of the energy-converting cells is at the same time the surface of the structural member; it consists of material which is light-transmitting (translucent) and resistant (fast) to light (photostable), stable, resistant to environmental influences and, as the case may be, impact-resistant (unbreakable). The energy-converting cells can be used as bearing or non-bearing elements, and can be produced as prefabricated components. The energy produced in the energy-converting cells is led to accumulators installed at the site of use, and excess energy is fed into regional grids.

IPC: D06F34/28
Filed: 1988-02-04
Abstract: A household appliance is equipped with a programmer for the control of various selectable working programmes. In this connection, in order to simplify the selection of the working programme and to make manual intervention unnecessary, the selection of a working programme is achieved through the recognition and evaluation of a code word spoken by the appliance user. Provided for this purpose is a sonic transducer (7) with post-connected speech analyser (6), from which the analysis signal is compared, by means of a processor (1), with individual speech pattern signals of a speech pattern memory (8). Each memory location has assigned to it in this case a working programme, corresponding to individual pushbuttons (5) of a manually operable switching device (4). The processor (1) then launches, via a programme controller (2) with which it is in dialogue, the control of electrical devices (3) of the household appliance, according to the programme. Additionally, in one speech pattern memory (8), a plurality of memory locations are provided for the storage of a plurality of code words, which are assigned to the same functions and, for example, are expressions coloured by dialect or in a foreign language. The memory locations can be optionally populated with new code words. So that the most frequently used code words are not cleared, each newly input or newly called-up code word has time-dependent information added, which is compared in each case of new input in such a manner that only the ... which has remained unused the longest ....

Title: Apparatus for filtering flowable material to be filtered
Inventor: KNAUER JOACHIM FRIEDRICH
IPC: B01D25/00
Filed: 1988-03-08
Abstract: There is an apparatus in which a high-pressure pump 1, furnished with a drive 3, operates on a filter press 8 in which a growing counter-pressure builds up, the throughput of the high-pressure pump 1 decreasing with increasing counter-pressure of the filter press 8 and in which the drive 3 of the high-pressure pump 1 is furnished with on and off switches. It is desired that the maximum filling of the filter press is achieved in a shortened time. This is achieved by a computer 12, to which are sent the results of throughput measurements 10 and counterpressure measurements 11, adjusting the drive 3 and thus the entire throughput in a manner such that the counter-pressure builds up in dependence on the time essentially continuously, i.e. without noticeable steps. By keeping the increase of the counterpressure constant, a filter cake is built up in the filter press which makes possible complete filling of the filter press with a greatly decreased time. <IMAGE>
