Patent DE-4130846-A1 (DE)
Inventor: BADUR KLAUS
IPC: G01M15/00
Filed: 1991-09-17
Abstract: The aim is to test production engines with regard to their ability to function by means of so-called cold tests. Such cold tests have hitherto only been possible for combustion engines as such. It has hitherto not been possible to test the individual components of the combustion engine, in particular the injection system, by means of cold tests with the engine driven externally. It is the object of the invention to make this possible. The procedure according to the invention, for testing components in internal combustion engines, is based on comparing measured values obtained during the cold testing of the engine alone with measured values which have been achieved with the component to be tested while driving the engine externally. The procedure according to the invention is particularly suitable for testing injection valves (10), system-pressure regulators (11) and idle-speed actuators (12) of Otto engines. <IMAGE>

Abstract: In order to improve a process for treating the backwash liquid of a backwash filter in such a way that it can be carried out more economically and is more reliable than known processes, it is proposed that the backwash liquid conducted away from the backwash filter be subjected to a sedimentation process and during this be at least intermittently subjected to pressure and that after completion of the sedimentation process, the backwash liquid be separated off in a pressure-tight manner from at least a part of the sediment thus obtained and the latter be then removed and a part of the backwash liquid, which is at least substantially freed from dirt particles, be returned to the cleaning process. In addition it is proposed to improve a sedimentation device having a sedimentation vessel (26), which includes a first region (32) for receiving cleaning liquid to be treated by sedimentation and a sediment collection region (34) located below, by the first region (32) and the sediment collection region (34) being able to be separated from each other in a pressure-tight manner by means of a separating apparatus (36) and by the sediment collection region (34) being provided with a vessel outlet (42), which can be closed by a closure (40), for conducting away the sediment. <IMAGE>

Title: Melting of pig iron@ without coking coal - comprises allowing agglomerate of ore, coal and bonding agent to stream down from top of cupola furnace, heating with gas stream and contacting with bed of ceramic spheres
Inventor: HOFMANN WERNER DR ING
IPC: C21B11/02
Filed: 1991-11-25
Abstract: Melting pig iron consists of the following stages. An agglomerate made up of iron ore, coal and a bonding agent is introduced into the top part of a cupola furnace. The agglomerate is allowed to stream downwards and is subsequently heated to a temp. above 1000 deg.C by gases flowing through the furnace. The charge is converted into molten pig iron and slag using contacting spheres of a heated ceramic bed. The liq. pig iron passes through the ceramic bed and falls into the base structure of the furnace from where it is drawn off. The pressure in the initial redn. zone in the top part of the furnace is kept higher than 1.3 bar. The air for generation of combustion gases is preheated and enriched with oxygen. The fuel (gases, oil or powdered coal) introduced for this purpose undergoes complete combustion. The agglomerate is introduced in the form of briquettes to reduce the resistance to the opposing flow of the combustion gas. Oxygen is added to the combustion gases in the agglomerate reduction region to burn off the resulting carbon monoxide. New spheres are added to compensate the wear of the ceramic bed. USE/ADVANTAGE - The invention can be used in metallurgical plants producing pig iron intermittently or in amts. not warranting the use of blast furnaces. The process does not require coking coal for reduction, and allows arbitrary fuels to be used for heating.

Title: Loudspeaker prodn. for increasing acoustic pressure or giving determined resonant response - comprises bonding metallised piezoceramic disc to metal carrier plate with non-conductive adhesive contg. filler with specified viscosity
Inventor: BERTHOLD HEINRICH DIPL ING
IPC: G10K9/122
Filed: 1991-12-20
Abstract: Prodn. comprises adhesively bonding a metallised piezo ceramic disc to a larger metal carrier plate. The adhesive is a non-conductive material contg. a filler with a dynamic viscosity of 800-100000 mPa/s. USE/ADVANTAGE - The system is used for mounting in a housing to increase acoustic pressure or give a determined resonant response. The unit can be fitted and mounted by ultrasonic welding without damage. In an example, an adhesive of 0.02g bicomponent Permabond E32 (RTM) epoxy resin with a viscosity of about 80000 mPa/s is applied by screen printing centrally to a metal carrier plate with a dia. of 46mm. A piezoceramic with a dia. of 25mm and a thickness of 0.1mm is laid on it. The bonding is applied by a die with a dia. of 24mm and at a pressure of 6 bar to spread the adhesive between the two. Surplus adhesive is spread outwards to form a beading round the edge of the piezoceramic without affecting the visible insulating edge of the ceramic. In the combined hardening stage, thermal and UV energy are used so that in the thermal stage at 80 deg.C, the adhesive is hardened in the gap between the two sections, and in the UV stage at 300-400 nm wavelength, the beading is hardened and the surface is hardened at a wavelength of less than 300 nm. The finished unit has high mechanical stability for operation up to very high acoustic pressure levels and can be subjected to ultrasonic welding within a thermoplastic housing at a light pressure without exceeding a temp. of about 80 deg.C. The ultrasound for bonding is by friction at the mating surfaces of the housing sections by a sonotrode at 20 kHz at right angles to the bonding surfaces.
