Title: Gas-fired heating unit operation - for low nitrogen oxide(s) emission, using oxidn. catalyst to reduce carbon mon:oxide emission
Inventor: RAGERT RAINER DIPL ING
IPC: B01D53/86
Filed: 1990-03-03
Abstract: In the operation of a gas-fired heating unit to form relatively innocuous off-gases, the novelty is that (a) measures are employed, in the gas burner-contg. combustion chamber of the heating unit, for controlling and/or modifying the burner flame so that the combustion gas NOx content is reduced with concomitant increase in CO content; and (b) the combustion gases are fed through a conduit, adjoining the combustion chamber, which contains a catalyst for post-oxidn. of the CO, the gases being passed through the catalyst at a location in the conduit at which the gas temp. at the end of the catalyst is still within the CO oxidn. process temp. range of the catalyst. ADVANTAGE - The process combines extremely low NOx emission with redn. of CO emission to below the prior art optimal threshold value.

Title: Rail heat treatment - forms angled transfer zone into untreated rail section to overcome any weakness
IPC: E01B11/44
Filed: 1990-07-31
Abstract: The sections of railway lines, and railway line parts, between heat-treated and untreated zones are formed by heating the treated section so that the transfer zone between the two sections runs at an angle to the longitudinal axis of the rail and its riding edge, into the untreated rail zone, as seen in plan from the riding surface. In changing the shape of the rail, the heat is applied at the end at an angle, using a gas burner or in induction coil, or a furnace with an angled opening. While the rail is being heated, a covering of heat-resistant material such as asbestos is passed over the rail to define the angled transfer zone between the heated and non-heated sections of the rail. The untreated section of the rail is heated as a short heat build-up zone at a temp. below the decarburistaion temp. of the rail, such as 400-500 deg.C.  ADVANTAGE - The technique prevents the development of projections and weakness in the rail, and the railway wheel does not rest on the whole transfer zone.

USE/ADVANTAGE - Producing sintered bodies of Si3N4 and SiC as cutting tools and ceramic parts in armatures and motor construction. By using a dicarbonyl compound, no significant increase in the oxygen content of the powder material is detected which leads to a higher high temp. strength in the sintered body as the prod. of low viscosity glass phase in the grain boundaries is prevented. The sintering agent is very well dispersed in the powder.

Title: Control circuit identifying misfiring of IC engine - analyses misfire signals to determine degree of misfire and adjust fuel injection
Inventor: FUKUI WATARU
IPC: F02P17/12
Filed: 1991-06-25
Abstract: The i.c. engine is fitted with a detection system for each cylinder to monitor the ion current from the spark plug discharge. The ion current is analysed to determine if a misfire has occured and to what degree. The processor separates genuine misfires from partial misfires, which still provide a spark, and from error signals attributed to noise etc. in the sensing circuit. The genuine misfires result in a cut-off in the fuel feed to the respective cylinder. The system generates a misfire signal if the ion current is below a set level. This signal is incremented and analysed. The peak signal as well as the incremental signal is measured to determine if the misfire is total. The fuel feed can be totally cut off or reduced by a programmed amount. ADVANTAGE - Even running; improved engine control.
Patent DE-4123692-A1 (DE)
Inventor: ROMANN PETER DIPL ING
IPC: F02M61/18
Filed: 1991-07-17
Abstract: A fuel injection valve with a thin perforated metal plate fitted on a valve seat member downstream of a valve seat surface is already known. Here, the perforated plate must be thick enough to prevent its bending as a result of the prevailing fuel pressure, but this adversely affects the preparation of the fuel which is injected through at least one aperture. The use of a thin perforated plate is therefore to be made possible in order to improve fuel preparation. The thin perforated plate (22) allocated to the valve seat member (18) is supported by a plate (26) with a through aperture (61) which is thicker than the perforated plate (22). This effectively prevents any undesirable bending of the perforated plate (22) and at the same time improves the fuel preparation at the injection apertures (37). The supporting plate (26) is pot shaped and is welded together with the perforated plate (22) to the valve seat member (18) by a circumferential weld seam (24). The fuel injection valve may be used in fuel injection systems of compressed-mixture spark-ignition internal combustion engines.
