Title: Calcium carbide prodn. using oxygen@ blown converter in two=stage process - by increasing temp. of 1st stage and 2nd to reduce iron carbide
Inventor: GRUNDMANN HORST
IPC: C01B32/942
Filed: 1991-01-30
Abstract: CaC2 prodn. is by heating molten pig Fe and lime in an oxygen converter to above 1650 deg.C, O2 is fed to initiate an exothermic reaction and redn e.g. the Fe3Co. CaC2 is formed by feeding in C. Pref. first stage O2 blowing lasts for about 15 min and is controlled so that the C in the melt does not go below 0.5%. Co produced is collected and reused. Amt. of time used in the first stage is 1/5 the amt. of pig Fe. Speed of the second stage process may be increased by bottom blowing the converter with argon. This endothermic reaction takes place with several additions of Fe3C to maintain the temp. ADVANTAGE - O2 converter process lends itself to the production of CaC2 as the exothermic reaction in the first stage produces the heat required to establish the optimal conditions needed, i.e. the C has better solubility in the Fe and the C has better reactivity with other materials notably

During transport along a circular path the portions can be compressed by pressure directed radially outwards. A fluid such as water can be sprayed onto the portions of filling material, more particularly before their compression. USE/ADVANTAGE - Improved continuous prodn of packets of chewing tobacco.
Patent DE-4114087-A1 (DE)
Inventor: HARTMANN UWE
IPC: F02P11/06
Filed: 1991-04-30
Abstract: An ignition system for internal combustion engines is characterized by a high degree of freedom from misfires together with minimal electrode burning. To this end, an ignition device (5) associated with each cyclinder is switched on in synchronization with the theoretical ignition point for the corresponding cylinder and, when switched on, may deliver an ignition current to the park plug for an indefinite period. When the air/fuel mixture in this cylinder is ignited, a sensor (1) detects the burning in the cylinder and immediately switches off the ignition device (5). In any case, the ignition device (5) of every cylinder is switched off after a predetermined maximum time-interval has elapsed, i.e., even if no burning has taken place. In one variant, the ignition device (5) is first switched off in any case independently of the sensor after a time-interval equal to the normal delay between switch-on of the ignition device and burning and then switched on again when and only when no burning is or has been detected by the sensor (1).
