Title: Method for measuring the concentration by total reflection spectroscopy
Inventor: MUELLER G
IPC: G01N21/55
Filed: 1979-08-02
Abstract: In a method for measuring the concentration by means of total reflection (ATR Spectroscopy), a transparent material with a high reflection index is used to regenerate a clean optical surface pertaining to the reflecting elements. This substance acts as an intermediate layer (12, 15) between the reflecting element (4) and the sample (6).

Title: Machine capable of working as an engine,a compressor or a pump
Inventor: HIMBERT J
IPC: F01C21/08
Filed: 1981-08-13
Abstract: In the casing of the machine, which has a non-circular cross section, an axial piston (38, 39) rotates. Sealing blades (18) are arranged between the axial piston and the inner wall of the casing. Sealing blades, for example of a Wankel engine, abut directly on the inner wall of the working chambers; the invention proposes to rotate the flanges (20, 40), which define the front faces of the working chambers, together with the axial piston, to arrange the sealing blade in the slots of the flange (40), and to arrange a section of the casing (24) on the outer face of the flange which has the same diameter as the inner wall of the casing defining the working chamber and on which bear the sealing blades. The centrifugal forces are absorbed in the outer portions of the casing, hence in a region which is not subject to the very high temperatures of the working chambers.

After decoding said states, is displayed on a display device the decimal figure which corresponds to the code of the label.
Patent WO-9007053-A1 (WO)
Inventor: KLENK MARTIN
IPC: F02D41/18
Filed: 1989-11-29
Abstract: L'un des deux procédés de détermination d'une quantité de carburant est caractérisé en ce que l'on calcule la pression du collecteur d'admission prévue pour la course d'admission suivante et que l'on détermine sur cette base la quantité de carburant à injecter pour la course d'admission suivante. Le second procédé est caractérisé en ce que l'on corrige la quantité d'air déterminée à l'aide de la pression du collecteur d'admission à l'aide d'un modèle qui tient compte des effets de la température. Ces procédé contribuent tous deux à un meilleur calcul des quantités de carburant, ce qui est particulièrement avantageux dans le cas des transitions instationnaires. A l'aide des quantités d'air calculées à l'avance, on peut aussi régler avantageusement le moment d'allumage.
