Title: Method and agent for influencing the combustion in internal combustion engines
Inventor: LOHBERG WERNER
IPC: F02M25/022
Filed: 1986-11-03
Abstract: The object is to improve the combustion in an internal combustion engine with metered feeding of a moderating agent and to reduce the pollutant emissions and simplify the metering process. 0.5 to 5 per cent hydrogen peroxide is added to the moderating agent, water. The moderating agent is fed as a mist or vapour to the combustion chamber as a function of the engine speed or the fuel consumption. The addition of surface-active agents to the moderating agent promotes the formation of minute mist droplets, which feed active oxygen, released in the combustion, directly to the added fuel mist. The method and agent can be used in internal combustion engines with carburettor or fuel injection.

Title: Method and circuit arrangement for generating a phase-shifted digital signal
Inventor: REIN HANS-MARTIN PROF DR
IPC: H03K5/135
Filed: 1987-04-06
Abstract: The invention relates to a method for generating a digital signal which is shifted by an arbitrary adjustable phase value between 0 and pi , particularly a high-frequency clock signal, using conventional phase shifters which can be continuously adjusted between 0 and  pi /2 or, respectively, 3 pi /4, and is characterised by the fact that the frequency of the original signal is halved by means of a frequency divider, that frequency shifts of 0, - pi /2 and - pi  of the frequency-divided signal are generated, that two controllable phase shifters of the conventional type are used in such a manner that the first one is fed by the undelayed signal and, respectively, the frequency-halved signal phase-shifted by - pi /2 at its two inputs and that the second one is fed with the frequency-halved signal phase-shifted by - pi /2 and, respectively, with the frequency-halved signal phase-shifted by - pi  at its two inputs and that they are jointly activated and, as a result, can generate continuous phase values in the ranges from 0 to - pi /2 and - pi /2 to - pi  which can be arbitrarily input, that then the frequency of the signal thus phase-shifted is doubled again so that phase shift values of between 0 and  pi  are produced. <IMAGE>

Title: Clean-room ceiling system
Inventor: ZIEMER WOLF DIPL ING
IPC: B01D46/52
Filed: 1987-05-07
Abstract: There is described a clean-room ceiling system having a supporting profile which is suspended from a ready-installed structure by suspension means and is in the form of longitudinal and transverse beams which are symmetrical with the Z-axis and have horizontal flanges, for the installation of suspended-matter filters from below, and sealing strips between the flanges and the filter frames. The essential feature of the invention is that, for partial compression of the sealing strips (3), (18) between the flanges (20) and the filter frames (25 and 27), a metallic contact via a corresponding spacing element (30, 38) is provided. Furthermore, the filter frame (25) has flanges (27) which point horizontally outwards for fastening to the supporting profile (1). This affords the advantage that a constant sealing-off of the dust side from the clean-room side is obtained, and that rapid and trouble-free mounting or exchange of the filters can be carried out from below (24). <IMAGE>
Patent DE-3716326-A1 (DE)
Title: Propeller
Inventor: OEHLER CLAUS DR ING
IPC: F04D29/32
Filed: 1987-05-15
Abstract: In the case of a propeller for thrust generators, volume flow generators or wind energy converters which are acted on by air, the blade tips (14) of the vanes (12) which project essentially radially from the hub (10) pass through different circular paths (16), in order to reduce the noise. For this purpose, the vanes (12) advantageously have different lengths. In order to compensate for the unbalance induced thereby, an asymmetric arrangement was selected, with different angular separations between the vanes. According to a modified embodiment, the vanes are aligned on the hub such that the circular paths on which the blade tips run are arranged in planes which are parallel to one another but are axially offset with respect to one another. <IMAGE>

Title: Process for preparing sodium sulphate
Inventor: HOFMANN GUENTER DIPL ING
IPC: B01D36/00
Filed: 1987-06-26
Abstract: The invention relates to a process for preparing a pure, crystalline sodium sulphate by working up natural minerals which contain, besides thenardite and/or mirabilite, additionally glauberite, calcium sulphate and water-insoluble naturally occurring materials in the form of magnesium aluminium silicates. A process is proposed which, with as small as possible a plant expense, makes possible a pure crystalline sodium sulphate from naturally occurring minerals having a sodium sulphate content below 50 %, characterised in that the raw natural minerals are mixed with water, that this slurry is cooled until the dissolved sodium sulphate crystallises out in the form of Glauber's salt, that the Glauber's salt is separated from the mother liquor and is again dissolved in water, that the aqueous solution is admixed with a flocculation aid and that the sodium sulphate is, after separating the undissolved solids from this solution, recovered by crystallisation according to a conventional process. <IMAGE>

IPC: E05B63/12
Filed: 1987-10-26
Abstract: With the locks known at the present time, doors or the like can be locked in a burglar-proof manner only if the locking plate or the locking bolt is transferred into the locking position by means of a key. In the newly developed lock, simply pulling the door shut will already lock in a burglar-proof manner the latch which thereby engages in the frame. After the actual locking operation, the latch is secured by one or more retaining members, in such a way that it can no longer be pushed back into the lock without the actuation of the actuating members provided. During the unlocking of the latch, the retaining members, that is to say the fastening points, are released before the actual unlocking operation. The lock is suitable for all doors or the like, especially for all wing elements, and, with appropriate extensions, is also used in conjunction with multi-point locking systems, electrical door openers, etc.
