Title: Bottom blowing converter blast system - using octagonal lime-oxygen loop for tuyeres shrouded by enveloping gas tubes
Inventor: STEPHAN RAYMOND CLINTON
IPC: C21C5/48
Filed: 1973-09-14
Abstract: A system to feed oxygen, lime and an enveloping gas into a quality-basic oxygen process converter consists of a closed-loop distributing main below the converter bottom, with branch pipes to take the lime entrained by the oxygen to the tuyeres. At two points, a fresh oxygen/lime mixture can be added to the loop. Flexible hoses carry the enveloping gas from a central point to each tuyere where it shrouds the oxygen/lime tube in the annulus left be a concentric outer tube. This eliminates the conventional cylindrical collector and facilitates the individual exchange of tuyeres. Damage on one does not involve other tuyeres; the system is simpler and requires less upkeep.

Title: Composite model railway track intersection or loop - uses separate curved elements to build up complete circle
Inventor: SEEBERGER GUENTHER
IPC: A63H19/32
Filed: 1973-11-29
Abstract: The railway track intersection is derived from a radially arranged system in which the radius of curvature of the track is 9.87 or 9.74 times the length of arc subtended by the radius from the centre of curvature. By employing either single lengths of this curved track or multiples of such lengths it is possible to construct a total length of curved track turning through any number of degrees up to 360 deg. The choice of the numbers 9.87 or 9.74 is justified by mathematical considerations with respect to an approximate value of pi, the square root of ten, and the metric equivalent (2.54 cm) of the inch.

Title: Beer filling system for bulk shipment tanks - uses pressurising air which is freed from oxygen in reactor before entering tanks
Inventor: KRUEGER ECKHARD PROF DR ING
IPC: B67C3/06
Filed: 1974-02-21
Abstract: Beer filling system involves the use of air low in oxygen for pressurising the shipment tanks prior to filling these with beer. Oxygen is removed from the compressed air supplied by compressor, in a reactor for this purpose. Preferably an air in the tanks prior to filling is circulated through the reactor to remove the oxygen content. In this way all air coming into contact with the beer is freed from oxygen and thus should have no effect on the taste and storage properties of the beer as tanked, prior to the bottling operation. When the air is circulated through the reactor to remove its oxygen, it is recirculated several times until the last trace of oxygen has been eliminated.
Patent DE-2418356-A1 (DE)
Title: Pickling of steel - in a cold oxidizing bath followed by coagulation of the ferricompounds in a hot medium
Inventor: HEIMBERGER WALTER DR ING
IPC: C23G1/08
Filed: 1974-04-16
Abstract: Steel is treated in a prepickling bath in known manner and then without washing in water, and after cooling, in a non-heated oxidising pickling bath in which the ferro cpds. are converted into molecular dissolved ferri cpds. The steel is subsequently treated in a hot bath at 80 degrees C in which the ferri cpds. are converted into colloids which are coagulated forming an insoluble sludge floating on the surface of the bath. The sludge is easily removed from the surface. The oxidation bath and pptn. bath is made up from an aq. stock soln. of HNO3, H2O2 (acid to peroxide ratio is 1:2 and 2:1), and a buffer which, before use, is suitably diluted with water. The oxidation bath is regenerated not always by addn. of fresh stock, but occasionally by adding H2O2 without other addns. Process eliminates the wash stage between prepickling and pickling and does not require a post treatment. The process presents therefore a saving in costs and reduces problems associated with waste water treatment.
