Title: Device for passing steam into a liquid
Inventor: GOESLING ROLF ING GRAD
IPC: B01F5/04
Filed: 1984-01-25
Abstract: The device described comprises a liquid reservoir with a number of plunge pipes 11 which have steam flowing through them and whose inlet sides are connected to the steam supply and whose outlet ends open out into the liquid. According to the invention it is provided that at least one of the pipes has an outlet orifice 12 which is narrower than the free cross-section 15, and the internal profile of the pipe outlet end section 13 forms a nozzle-like transition from the pipe inner wall 16 to the outer edge 14 of the outlet orifice 12. If given such a shape, which is preferably provided for a plurality up to all of the plunge pipes, each pipe end has only a small flow resistance with respect to the outflowing steam, but has a high flow resistance with respect to liquid flowing into the pipe. As a result, it is possible to prevent an interfering effect designated as "steam-chugging", which is based on a sudden and violent influx of liquid into the pipes. <IMAGE>

Title: Process and device for preheating raw materials for glass production, in particular a batch of glass fragments
Inventor: ROLOFF HELMUT
IPC: C03B3/02
Filed: 1984-05-03
Abstract: In glass production, waste gases usually occur which, although they are normally used for preheating the fresh air for a glass-melting furnace, still have a residual temperature of 400-600 DEG C. In order to be able to utilise this residual energy effectively for preheating the raw materials for glass production, in particular glass fragments, the invention proposes leading the waste gases through a hopper (19) for the temporary storage of glass fragments (20) and thereby heating the batch of glass fragments (20) to up to 380 DEG C. The waste gases which are cooled and contaminated during the preheating of the batch of glass fragments (20) are in one proposal of the invention led via a wet scrubber (26) before they are led back into the waste gas duct (17) leading to the stack or the like. <IMAGE>

Title: Regulating device for obtaining stationary pressing forces during the compaction and conveying of dispersed solids using piston extruding presses, piston briquetting machines, piston solids pumps and piston pressing sluices
Inventor: HORRIGHS WOLFGANG DIPL ING
IPC: F04B49/12
Filed: 1985-01-29
Abstract: To obtain stationary pressing forces during the compaction and conveying of dispersed solids using piston extruding presses, piston briquetting machines, piston solids pumps and piston pressing sluices, a regulating device is presented which counteracts a deviation from the desired piston compacting pressure by axially adjusting the position of the top dead centre of the piston. This results in a modification of the friction ratios, which are of crucial importance for the pressure level, so that there is subsequent adjustment of the pressure ratios which exhibit a deviation. The axial adjustments which are to be carried out in displacement of the top dead centre of the piston are made possible by appropriate devices, the essential element of which comprises an adjusting element which is to be hydraulically or pneumatically actuated, it being possible to use different types of regulating system with different guide parameters (pressure and/or pressure and length of piston stroke). <IMAGE>

Title: Spark plug for internal-combustion engines with fuel injection
Inventor: SCHWAIGER ODILO
IPC: F23Q7/00
Filed: 1985-02-08
Abstract: The invention has two aspects of current importance: the protection of the economical combustion method for passenger car engines combined with prevention of the production of damaging NOx emissions in the exhaust gas. The invention modifies the diesel principle (self-ignition) into the pseudo-diesel principle in that the spark plug according to the invention serves not only, in a known manner, as a starting aid but, furthermore, in particular in direct fuel injection combustion methods, serves for the continuous introduction of the ignition of the fuel jets even after a short length of jet, in order to eliminate the delay in ignition which is unavoidable with self-ignition, during which delay the fuel usually passes completely into the combustion space and then suddenly oxidises resulting in very high peak pressures which cause the characteristic hard combustion noises and the high temperatures associated with the high pressures, furthermore the dominant component (T > 1800 K) of the complex conditions for the production of NOx pollution, the critical emissions in the exhaust gas in diesel engines. The spark plug is characterised by two stilt-like columns which protrude out of the spark plug housing and form the electrical poles between whose ends the ignition loop is arranged, furthermore it can be of single-pole or two-pole design (connected in parallel or in series) and have two (heating) power stages.

Filed: 1985-05-20
Abstract: The contact apparatus has at least two contact bodies and at least one segmented body. The latter possesses bars separated from each other by slots and having a curved central area. Furthermore, the bars have the form of a three-dimensional curve. In their end areas, the bars possess in each case a section curved in the opposite sense to said curved central area. Besides, the bars are linked together at their ends by means of edge strips. Moreover, the slots extend up to the curved section. In this way, points of contact clearly defined as regards their position and values are assigned to the convexity as well as the end areas of each bar. These measures lead to an improvement of the mechanical and electrical characteristics of the contact apparatus.
