Patent DE-3413417-A1 (DE)
Title: Sleeperless rail fastening
IPC: E01B9/68
Filed: 1984-04-10
Abstract: The rail fastening has a metal bearing plate (13) of high elasticity, which is underlaid with a rail bearing (14) made as an under-casting. The bearing plate (13) is systematically pretensioned by anchoring bolts (19) so that the surface pressure, with which the bearing plate (13) presses against the upper side of the rail bearing (14), is essentially constant over the entire width and does not subside at the plate edges. By means of this full-surface pretensioning, it is brought about that the transverse stresses which arise are transmitted from the bearing plate (13) to the hard rail bearing (14) without local tension peaks and without displacements. <IMAGE>

Title: Portable group filtration apparatus for obtaining drinking water from contaminated surface water, in particular a filtration unit comprising a hand pump, adaptor and disposable sterile filter therefor
Inventor: GRUNDMANN PETER WALTER
IPC: C02F9/00
Filed: 1985-04-19
Abstract: The present invention "portable group filtration apparatus for obtaining drinking water from contaminated surface water, in particular a filtration unit comprising a hand pump, adaptor and disposable sterile filter therefor", relates to a treatment apparatus which permits improved clarifying and/or sterile filtration versus known pressure filtration systems having pneumatic piston displacement pumps and disposable filter holders having a membrane filter. In this case, risk-free filtration of A/B/C-contaminated surface waters is possible via a by-pass-free sterile filter holder. A special disposable filter holder having a membrane filter package is provided which has a high filter surface area and is exposed to a restricted filter pressure in such a way that water situated in a pretreatment vessel can be sucked in via a 3-way adaptor and can only be passed into the disposable filter below a filter pressure which is preset within a narrow pressure range. As soon as a filter pressure is established which is higher than the preset filter pressure, the water remaining upstream of the disposable filter flows back into the pretreatment vessel via an open check valve. If the threshold pressure determining the opening pressure of the check valve is undershot, the safety valve closes so that the contaminated water again flows through the disposable filter holder.

Title: Washer system
Inventor: LIETZ JUERGEN H
IPC: B60S1/50
Filed: 1985-10-14
Abstract: The washer system for which a patent has been applied is a system in which the freezing of water or cleaning liquids mixed with de-icing agents in the washer systems of motor vehicles is avoided by virtue of the fact that the liquid is stored in a storage container which is insulated against the cold and has a heating device and by virtue of the fact that the liquid remaining behind in the line between the pump and the spray nozzle after the windscreen has been sprayed is sucked back into the storage container and heated and by virtue of the fact that the spray nozzle is protected against being cooled down by the relative wind by heat-insulating material (Patent P 3236839), and by further measures such as providing the metal tubes in the spray nozzle carrier and in the spray nozzle itself with an inner coating of silicone and by means of heat-conductive metal tubes which project into the engine compartment and are intended for the transportation of the liquid, the freezing up of liquid in this part of the system is prevented.
Patent DE-3536927-A1 (DE)
Title: NOx-decreasing measures in coal combustion
Inventor: HOELTER HEINZ DIPL ING
IPC: F23K1/04
Filed: 1985-10-17
Abstract: It is known, in the combustion of coal, to design the coal dust burners in such a way that, as a result of feeding the combustion air, they produce lower amounts of NOx than is conventionally the case. It is further known to reduce via catalysts the NOx value in the flue gas downstream of fossil-fuel combustion plants. According to the invention, it has now been found that with certain types of coal, preferably coal having high volatile proportions, preheating the coal significantly contributes to decreasing the NOx value in the combustion. The preheating can carry on up to the low-temperature carbonisation gas region. In the case of fluidised-bed fired plants, the coal is fed above the fluidised bed and with nozzle-fired plants, the feed of the preheated coal is carried out via the nozzles into the combustion chamber.
Patent DE-3539525-A1 (DE)
Title: Process for the extractive separation of hydrocarbons from an aqueous solution
Inventor: GOTTSCHLING RUDI DIPL ING
IPC: C02F1/26
Filed: 1985-11-07
Abstract: In a process for the extractive separation of hydrocarbons, and halogenated hydrocarbons, from an aqueous solution, to separate the constituents exploiting their differing solubility, the solution is brought into intimate contact with an extraction medium in an extraction stage. In a subsequent treatment stage, the extraction medium loaded with the hydrocarbons is subjected to a thermal separation process in order to separate the hydrocarbons and the extraction medium from each other and the latter is returned in circulation to the extraction stage. In order to carry out the process as operationally safely and inexpensively as possible and to obtain the components separated off for reuse or disposal, the invention provides the use of a methylsilicone oil, methylphenylsilicone oil, methylhydrogensilicone oil and/or polyoxyalkylene-modified silicone oil as extraction medium. In the treatment stage, the separation only needs to be carried out as far as is required for the extraction with the recycled extraction medium. Depending on the hydrocarbons to be separated off, silicone oils of different molecular weights are used.

Title: Laminar displacement current for the breathing region of the driver, preferably of a bus or heavy goods vehicle
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H3/06
Filed: 1985-12-06
Abstract: In the main application P 3541671.8, an arrangement is described with which bus drivers or heavy goods vehicle drivers are supplied with cleaned air in the breathing region with the aid of chemisorption filters and nozzle arrangements. In this embodiment, however, there is the risk of the air becoming contaminated again by undesired mixing due to cross-currents and turbulences on the way from the orifice of the nozzle arrangements to the breathing region. In order to eliminate these disadvantages, it is proposed according to the invention that the cleaned air current (6) emerging from the nozzle arrangement (5) is formed as a directionally stable laminar current, this air current (6) being additionally safeguarded by an edge-shielding air current (8). <IMAGE>
