Patent DE-4126255-A1 (DE)
Title: Improved conversion of silica to silicon@ using electro-furnace - comprises addn. of small amt. of magnesium silicate which improves the conversion of evaporated silicon mon:oxide
Inventor: LASK GERT-WILHELM DR
IPC: F27B1/09
Filed: 1991-08-08
Abstract: Silicon is mfd. by the conversion of quartz in an electro-furnace using a fill of preforms of fine quartz and a fine grained carbon medium as well as coarse quartz. The conversion consists of a first stage in which a coke structure with open pores is formed by the formation of Sic by reduction of fine grained SiO2. The second stage occurs in the bottom of the furnace and consists of redn. of coarse quartz by SiC under the formation of gaseous Si-oxide. The feature is that Mg-silicate is added to the preforms in a quantity which measures a Si yield improvement of at least 5 wt.%, pref. 10-20 wt.%. The furnace is operated in such a way that Mg-silicate in the upper parts is converted almost completely into Mg-carbide, pref. at a temp. below the m.pt., which converts the Si-oxide which is generated in the preforms and rises in the furnace. Also claimed are the use of other silicates in the preforms which are converted into carbides in the furnace, and a process for the formation of the preforms. USE/ADVANTAGE - The process improves the conversion yield of the process significantly without resulting in a large contamination of the end prod. by Mg, as this escapes at the end of the process. The contamination level can be made very low by using low contamination starting prods. The processes are assumed to occur as follows: MgSiO3 + 4C = MgC2 + SiO + 2CO then : MgC2 + 2SiO = Mg + 2Si + 2CO. The liq. Si is rapidly converted to the carbide : Si + C = SiC. The Mg formed is gaseous and reacts easily with the C to form new carbide : Mg + 2C = MgC2.

Patent DE-4131500-A1 (DE)
Inventor: REITER FERDINAND DIPL ING
IPC: F02M61/20
Filed: 1991-09-21
Abstract: A prior-art electromagnetically operable injection valve makes use of a helical return spring the ends of which are compressed and ground flat. A valve closer and a valve seat body can rotate circumferentially in relation to each other so that the continuous fresh mutual adjustment of the mating surfaces results in a travel which alters during operation with consequent variations in the quantity of fuel injected per stroke. The novel injection valve has a return spring (26) in which the ends (52, 53) of the spring are bowed, extend axially and parallel to a longitudinal valve spindle (11) and engage so as not to rotate in recesses (45) and (46) of a fixed adjusting bush (27) on one side and a needle bush (51) on the other. Thanks to the fixed angular position of the valve seat body (21) in relation to the valve closer (55) throughout the entire useful life of the valve, the adaptation process of the two components is restricted to a single running-in stage. The novel injection valve is especially suitable as an injection valve for fuel injection systems in mixture-compressing spark-ignition internal combustion engines.
