摘要:
A method is described for treating bacterially induced meningitis, comprising administering a prostane derivative of formula I or Ia ##STR1## wherein X.sup.1, X.sup.2, X.sup.3, X.sup.4, X.sup.5, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as described below, and the --O--R.sup.3 -- group is in the .alpha.- or .beta.-configuration. The prostane derivative can optionally comprise or serve as an adjuvant, and it can be administered in combination with an antiobiotic.

The invention relates to an analytical technique for the quantitative determination of an analyte and a reagent solution useful in said quantitative determination. The analytical technique is conveniently adapted for quantitative determination of carbonyl and even more particularly adapted for finishing an alcohol produced in the Oxo Process.

The invention relates to a pressure measuring line, particularly for invasive blood pressure measurement, which presents a wall made of a flexible material, which surrounds a passageway. The wall consists particularly of at least one inner hose and an outer hose enveloping the former, where the material of the inner hose is harder than the material of the outer hose, and the wall thickness of the inner hose is less than the wall thickness of the outer hose. The inner side of the outer hose is in full-surface contact with the outer side of the inner hose.

The invention concerns a valve arrangement installed in a hydraulic system including a housing (17a, 17b) which is provided with two connections (22, 23) and includes a closing element (14) which lies in a neutral position on a valve seat (6). In accordance with the invention, a valve element (11) is provided which has two step valves (15a, 15b), arranged at a distance, each being associated with one flow direction, whose the closing elements (14) are acted upon by a spring force.

In a mechanism for the drive of a tool spindle which performs a rotating indexing motion, particularly for the production of gear-wheels, a rocking lever is used which is connected by a displaceable sliding swivel joint to a second member such that linear motion is able to be executed by the second member thereby causing a linear adjusting movement in the indexing mechanism.

A Luer-Lock connector for medical devices with a tubular body and a swivel nut enclosing it and secured on it. The swivel nut has a radially inward-protruding edge and the tubular body has at least one radially outward-protruding elastic arm, whose end can be stopped against the edge.
摘要:
An apparatus for determining the wear of a mold wall during continuous casting of metal by using at least one distance measuring sensor disposed in the mold wall to measure the instantaneous distance from the sensor to the casting. The surface of the casting adjacent the mold wall may be irregular, so the minimum value of the distance between the sensor and casting is stored and used as the current distance between the sensor and the inner mold wall. Mold wear is determined by subtracting the current distance between the sensor and the inner mold wall from the original distance, before the abrasive casting process began. The sensor signals are also used to determine when the mold geometry should be adjusted to compensate for the wear. This is accomplished by storing the maximum distance between the sensor and casting and subtracting the current distance from this maximum, since the maximum distance increases as the casting shrinks away from the mold wall.
