Title: Device for guiding and driving a high-pressure spraying head
Inventor: SOLLINGER MICHAEL DR ING
IPC: B23Q5/34
Filed: 1989-02-13
Abstract: An especially light and compact device for guiding and driving a reciprocating high-pressure spraying head (14) is described for treating the surface of concrete. The spraying head (14) is arranged on an extension arm (11) which is articulatedly mounted on a guide element (10) which can, in its turn, be displaced on a guide rail (12). The extension arm (11) is supported by supporting rails (16, 17) in the vicinity of the spraying head (14). The linear drive is brought about by means of an endless cable (19) which is guided back and forth around a U-shaped track and is fastened twice to the extension arm (11).

Title: Ventilation nozzle for vehicle interiors
Inventor: BRUHNKE ULRICH DIPL ING
IPC: B60H1/34
Filed: 1989-03-16
Abstract: A ventilation nozzle for vehicle interiors has an air-outlet opening recessed in the interior soft trim, an air-ducting housing connected to the air-outlet opening and a closure for optionally closing the air-outlet opening. In order to obtain an aesthetic integration of the air-outlet opening in the interior soft trim, with the aim of rendering the air-outlet opening as invisible as possible when the ventilation nozzle is closed, the closure comprises a flexible cover which is connected on one side to the interior soft trim, and a driving device which can be switched on as desired, spreads the cover out, from its side connected to the interior soft trim, over the air-outlet opening and pulls it away from this again. The cover preferably has the same surface structure and colouring as the interior soft trim.

Title: Motor vehicle, especially an armoured motor vehicle, driven by an internal combustion engine
Inventor: WOHLFARTH PETER
IPC: B60K13/04
Filed: 1989-04-06
Abstract: A motor vehicle, especially an armoured motor vehicle, is described, which is driven by an internal combustion engine, the exhaust gases of which are cooled before emerging into the open air by mixing with cooler air delivered by a fan.

Patent DE-3918568-A1 (DE)
Title: Rotary slide valve with integral injection nozzle and adapted piston cavity for charge cycle control and mixture formation for supercharged four-stroke diesel engines
Inventor: JONITZ GERT
IPC: F02B75/02
Filed: 1989-06-07
Abstract: Four-valve technology and widely varying injection methods are currently used in order to improve the efficiency and to reduce sooting. The technological cost is correspondingly high. The new control is intended to regulate the said processes more effectively. By means of the supercharged fresh air and due to the design of the piston cavity, the rotary slide valve, which forms the entire cylinder head, (D rotary slide valve = 2 D cylinder) guarantees optimum scavenging, cooling and filling of the cylinder. The volumetric efficiency reaches almost 100%. A good mixture formation is achieved due to the rotating injection nozzle (in the rotary slide valve). Combustion is low in soot and the efficiency correspondingly high. The engine functions with equally good characteristics even at high speeds. Two sealing rings assume the function of the conventional cylinder head gasket. This control is especially suitable for supercharged four-stroke diesel engines. <IMAGE>

Title: Modular construction method for waste water purificn. system - in which central sedimentation chamber of modular construction elements is surrounded by biological water purificn. chamber
Inventor: SCHLEICH JOSEF DIPL ING
IPC: C02F3/28
Filed: 1989-11-21
Abstract: In a modular waste water cleaning and disposal sysetm, the central functioning space for sedimentation, pre-rotting, and final rotting and storage of sludge is made up of a floor shell and a roof shell of rectangular ground plan. The roof and floor consist of the number of unitary elements made of plastic, concrete, non-rusting metal plaets, etc. necessary to form an installation of the required size and capacity. The end  surfaces of the space thus formed are closed by flat or curved m elements in which the inlet and outlet pipes are preferably located.  A biological reactor space, enclosed below by a half shell element or a flat floor element, is arranged around this central space and is filled with gravel or crushed stone or plsatics particles of different sizes. This reactor space receives the distribution pipe and the outlet pipes at the appropriate elevations. The central space may be divided perpendicular to its axis, by curved partitions which do not extend to its floor, into a pre-rotting chamber and a  final rotting chamber. The construction elements making up the floor, roof, etc., may have an undulating or trapezoidal or U-shaped cross section, and may be reinforced by cast-in-place concrete. USE/ADVANTAGE - This invention comprises a modular construction method for a non-mechanical multi-function system for the treatment and disposal of waste water from domestic households, agriculture, or businesses of from two to one thousand inhabitants.
Patent DE-3942757-A1 (DE)
Inventor: ZANZIG HANS-JUERGEN DIPL ING
IPC: H04M1/58
Filed: 1989-12-23
Abstract: State of the art: Summing amplifiers with feedback operational amplifiers are generally known. 
<??>Technical problem: The weighting factors are quotients obtained from the feedback resistance common to all addends and the individual series resistances. Only the feedback resistance has a directly proportional effect. The individual series resistances have an inversely proportional effect. The formation of pre-defined complex weighting factors is impeded. The problem occurs, for example, in two-wire/four-wire interfaces. 
<??>Fundamental principle: Two-stage summing amplifier, where the second stage (VS2') adds up using real factors and complex factors are implemented in the first stage (VS1'). 
<??>Advantages: Interfaces which are balanced and unbalanced about earth are equally simple to implement with one capacitor only. In-phase signals can be evaluated (SSE) with ease; in-phase signalling (DS) is possible.
