Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a device for detachably attaching a lens tube (2) to a lens barrel (1). It is characterized in that the lens barrel inside its forward free edge (5) is provided with peripheral grooves (3) extending in the same plane, the respective bottom of which at the ends (9) of the groove inclined in said plane transforms into the shell surface of the barrel (1), which shell surface tapers conically (6) to the free edge (5) of the barrel. A guide shoulder (4) tapering in wedge-shape thereto is located on the shell surface between two adjacent grooves (3). The tube (2) is provided with radially resilient hooks (11) capable at mounted tube (2) to engage with the grooves (3) of the barrel (1).

Abstract: The invention relates to a device for data recording at photographic cameras equipped with a separate film magazine. The device according to the invention is characterized in that it is designed as a separate unit (3), which can be attached detachably on the film magazine (1), and which comprises a microprocessor (8) for controlling predetermined information and a necessary power source (9) as well as optical means (5,13) for information transfer to the emulsion side of the film (1) while the film is being advanced.

Abstract: A circular horizontal slide magazine intended for use with a film slide projector of the type in which sequential slides are released down into a position of preparedness, and then to a projection position, with the previous slide being returned to the magazine. This invention obviates the necessity of the magazine having one slide compartment which must be left empty by providing a manually operated locking mechanism which operates to prevent all of the slides from being released from the magazine.
