The present invention relates to a method of automatically cutting indexes and an automatic index cutting machine for carrying out the method. The index cutting machine is constructed of number of modules where each module includes a counting arrangement which functions to count a predetermined number of pages automatically for a specific index indentation, and a knife arrangement for cutting this predetermined number of pages. The book is transported between the modules hanging from a transporting arrangement which includes a transporter to hold the book hanging from its spine. Each module counts up to an index indentation and the index indentation is then cut in the knife arrangement, whereafter the book is transported to the next module in which a count is made to the next index indentation and this index indentation is cut. This procedure is repeated module after module.

The present invention is drawn to a system to be used for measuring NO levels in exhaled breathing air. The system comprises: (i) a face mask that tightly covers the nose and/or mouth of the individual that the mask is intended to be used on; (ii) an inlet unit for inhaled breathing air, (iii) an outlet unit for exhaled breathing air, (iv) a non-rebreathing valve through which inhaled and exhaled breathing air, respectively, passes, and (v) a measuring unit for NO connected to the outlet unit. The present invention furthers encompasses a method for the diagnosis in mammals of inflammatory conditions in the airways. The characteristic feature is that nitric oxide NO is measured in exhaled breathing air and a found abnormal level is taken as an indication of an inflammatory condition in the airways.

This invention relates to an arrangement for driving a high-frequency oscillating tool arrangement (1) which includes, inter alia, a device (1a) whose form changes with a change in voltage, utilizing an electric drive circuit (2) constructed to generate alternating voltage which can be connected to the device and the frequency of which is adapted, through a first control circuit (7), to a value (C1, L1) which momentarily corresponds to the resonance frequency of the reactive element which varies during a working operation. The first control circuit (7) is constructed to control momentary frequency in dependence on momentary phase difference between the current and voltage values of the alternating voltage. A second control circuit (4) is intended to control an inductive element (12) included in an oscillation circuit having a capacitive element (C2) corresponding, inter alia, to the form-changing device, such that the inductive element (C2) will obtain a value (1a) which corresponds to resonance for the prevailing alternating voltage frequency.
