Patent DE-3819100-A1 (DE)
Inventor: SCHULDT HANS-PETER
IPC: G01N33/00
Filed: 1988-06-04
Abstract: In an apparatus for the automatic calibration of gas sensors which, in particular, are combined in a gas detection system having a multiplicity of measuring heads which are connected to central evaluation electronics and carrying gas sensors, it is proposed for the purpose of facilitating perfect calibration by one man that when a calibration device in the preferred form of a calibration cap is placed on the measuring head in conjunction with the simultaneous provision of a flow of a calibration gas to the gas-sensitive region of the particular sensor a calibration signal is fed to the measuring head electronics and is relayed by the latter to the central evaluation electronics, which thereupon confirm the entry into the calibration phase, automatically recognise the particular calibration gas, automatically monitor the calibration process, automatically accept the particular calibration value, and in so doing continuously inform the operator, who is feeding the test gas, about the course of the calibration process. <IMAGE>

Patent DE-3827936-A1 (DE)
Title: Equipment and process for reducing the entrained slag fraction with the least possible residual steel quantity in the converter
Inventor: BERNER KLAUS DR ING
IPC: C21C5/46
Filed: 1988-08-12
Abstract: When converters are tapped, slag is also entrained with the steel towards the end of tapping. The fraction of entrained slag must be minimised with the least possible residual steel quantity in the converter, in order to improve the accuracy of analysis, the degree of purity and the output. The cause of the entrainment of slag is essentially the formation of an eddy and of a sunk chute above the tap hole when the level drops below the critical height of steel baths. According to the invention, a depression is therefore created around the tap hole, the height of which depression is greater than the critical bath height for eddy formation and in which weirs, inert gas inlets and/or coils for producing flows in the steel bath and measuring instruments for detecting slag entrainment are arranged in order to prevent eddy formation. The process provides for uniformly filling the depression up to the end of tapping, if appropriate increasing the slag stiffness by means of lime and/or disturbing the eddy flow of the melt by pulsed introduction of inert gas and/or by electromagnetic fields. By means of the novel equipment and the process, the formation of the eddy is very largely prevented, and this leads to the advantage of an improvement in the accuracy of analysis, the degree of purity and the output of steel when tapping converters. <IMAGE>

The castings removed from the moulds are conditioned at 780 to 850 DEG C for from 6 to 30 hours. The conditioned castings are finally treated for 6 hours at a temperature of from 600 to 820 DEG C in an oxygen atmosphere. 
<??>The castings can be converted into mouldings of any desired dimensions by mechanical methods before conditioning. 
<??>The shape and dimensions of the mouldings can also be determined through the shape and dimensions of the mould used in the production of the castings.

Patent DE-3911188-A1 (DE)
Inventor: TESTIN WILLIAM JOHN
IPC: G06F11/14
Filed: 1989-04-06
Abstract: A microprocessor initialization assurance system includes a normally open, momentarily closed on-off switch, Z4, which assures that the microprocessor has completed the initialization routine. First and second charge storage means 17, 19 are responsive to the switch to place the microprocessor in a reset mode upon the closure of the switch. The ratio of capacitances of capacitors 17, 19 is such that the first capacitor is recharged before the person actuating the switch has released it. This ensures that adequate time is allowed for the microprocessor, 11, to reset. Closure of the on-off switch produces a logic low level state at the input terminal 13 of the processor which state is sensed and indicates that the TV receiver, controlled by the processor, is to be turned on or off, whichever is the opposite condition to that which currently obtains. <IMAGE>
