IPC: G01N27/416
Filed: 1989-07-25
Abstract: A pre-determined amount of solubilized reagent is reacted 
to release CO₂ in a controlled-temperature reaction vessel 
and a controlled-pressure area adjacent the reaction 
vessel.  
     The devices that enable the system to be maintained in the 
liquid phase, and the reaction vessel itself, are 
controlled, assuming that the O₂ in the solution is such 
as that deriving from the presence of O₂ in the 
atmosphere, if necessary corrected for the effect of the 
reaction producing CO₂.  
     Thus, the amount of reagent taking part in the reaction 
being known, either by assay or by controlling the 
reaction time, by controlling the amount of O₂ in the 
solution containing the reagent, the barometric pressure, 
the temperature in the reaction vessel, and the 
coefficients of solubility of the two gases, it becomes 
possible to predict the partial pressures of O₂ and CO₂ in 
the liquid phase produced, which liquid phase is suitable 
for use as a calibration substance for an apparatus for 
measuring blood gases.

Title: Device for editing spoken text stored on a magnetic tape and/or in a semiconductor memory
IPC: G11B27/036
Filed: 1990-06-30
Abstract: 2.1. In conventional dictating machines, magnetic tape stores are used for storing the dictation. It is also possible to store the dictation in a semiconductor store. A dictating machine with a semiconductor store the storage capacity of which corresponds to the storage capacity of a magnetic tape store is a relatively expensive device. 2.2. By combining magnetic tape and semiconductor stores in accordance with the invention, the advantages of both families of stores are combined and it is possible to edit a dictation in a surprisingly simple manner. In a first embodiment, the dictation is temporarily stored in the semiconductor store. It is only after the temporarily stored text has been monitored and if necessary edited that it is written into the magnetic tape store. In a second embodiment, the semiconductor store is only used for temporarily storing the new text section. The new text section is read out of the semiconductor store in such a manner that the end of the new text section is gaplessly joined to the original text contained in the magnetic tape store. 2.3. The circuit arrangement according to the invention enables corrections to be carried out in any passages and of any length. By storing the edited dictation in the magnetic tape store, it is possible to continue to use conventional replay machines. <IMAGE>
