A reflectance spectroscope, which is provided with one or more optical paths which prevent substantially all singly reflected light rays from reaching the intended destination(s), is provided with a source of illumination for generating light rays, a support member adapted to support a reagent pad, the support member having a position in which the reagent pad is illuminated by the light rays gener...

The invention is directed to a method for allocating the wheel positions to air pressure control devices (6a to 6d) in an air pressure control system and is directed to an air pressure control system for carrying out the method. First measuring devices are provided which are permanently allocated to air pressure control devices 6a to 6d, and a second set of measuring devices 4a to 4d is provided w...

The invention provides an optic coupler for a fiber optic system, having a single coupler, a first optical port, a second optical port, a system port and a detector port. The first optical port responds to and provides a first forward optical signal. The second optical port responds to and provides a second forward optical signal. The single coupler responds to the first forward optical signal and...

The present invention relates to a device (1) at an implant (2) for closing a passage (3), as e.g. an aperture through the auricle diaphragm (4) or the ventricle diaphragm of a heart (5) or in a body channel and comprising a closing body which is fixable at the passage. According to the invention, a fluid tight closing body (6) which is expanding and stiffening in a radial direction is arranged t...

The polymer compounds according to the invention prepared from specific amidines, zinc mercapto compounds and elastomers are ideally suitable for the production of thermally stable rubber vulcanisates containing halogen. The vulcanisates of rubbers containing halogen obtained by means of the polymer compounds are distinguished by a reduced tendency towards unwanted post-vulcanisation and, at eleva...

The demonstration plates (1-5) can turn around their suspension axes. Each plate has a projecting component (6) which extends outwards horizontally from a position near one corner of the plate. This component works in conjunction with one of the rails (7,8) so that when the plate is turned around the suspension axis the component is brought into contact with one of the rails and stops movement. - ...

Apart from a memory component, further components are incorporated for processing telephone subscriber data, feeding in (2) a search order by a user, and for presenting (3) information for a user. The information contained in the unit (1) covers names, addresses, telephone numbers, tele-facsimile numbers and/or E-mail addresses. It also has capacity to include subscriber information in the form of...

A method for removing e.g. heavy metals from e.g. process effluent such as scrubber or condensate water in biofuel-burning power stations - comprises cooling the ash from the furnace with water and then using the high pH ash water to precipitate heavy metals from the effluent.

The invention relates to a navigation system receiver comprising at least two antennas one of which is a "reference" antenna A multiplexer multiplexes the signals from the antennas and a first processor situated downstream from the multiplexer delivers at least one navigation parameter on the basis of the signals from the multiplexer . The receiver includes a second processor having an input recei...
