Abstract: Rails are fixed by a W-shaped steel spring clamp (9) made from bar steel, in which the central part passes round the shank of a square-headed bolt (11) anchored in a slot (10a, 10b) in the ribs (3a, 3b) of the sole plate (3); the free and closely-located ends (9a) of the clamp (9) exert a pressure on the rail foot (1a, 1b) and the pressure arms (9c) of the clamp (9) opposite the rail foot (1a, 1b) press on the outer side of the ribs (3a, 3b) of the sole plate. To enable pre-assembly, the free ends (9a') of the clamp (9') rest, in the pre-assembly position, on the upper surface of the ribs (3a, 3b) of the sole plate (3) in such a way that they provide a tight closure with the lower edge of the ribs and the two clamps of a support point form a rail-guide with their two free ends. In the assembly position, the free ends (9a) of the clamp (9) press on the rail foot (1a, 1b), by means of the square-headed bolt (11). The middle part (9e) is then located slightly above (a) the rail foot (1a, 1b) and the pressure arms (9c) opposite the rail foot rest on the outer side of the ribs (3a, 3b) and press on the sole-plate (3).

Abstract: A distributed sensor system including an optical source (100) having a short coherence length for optionally continuously monitoring each sensor in the system. In one preferred embodiment, an array of fiber-optic sensors (110) are organized in a ladder configuration, with the sensors positioned in spaced relation and defining the rungs of the ladder. Light transmitted through the sensors is multiplexed onto a return arm (114) of the ladder, with sensor spacing being such that interference between light from different sensors is prevented. The multiplexed signals are received by an optical fiber receiver (118, 120) which couples the mutiplexed light with an interfering optical reference signal to produce a phase difference signal representing conditions influencing selected sensors. Embodiments are disclosed for use of either pulsed or continuous wave light sources. In another preferred embodiment, the sensors comprise a plurality of interferometers (404,406) connected in series configuration by a common optical fiber (402), which provides multiplexed output signals from the sensors to another plurality of interferometers (418, 420) comprising receivers. Functional equivalents of the series configuration provide sensors and receivers comprising birefringent or two-mode fiber. The optical path length differences between each pair of sensor arms (409, 410, 411 and 412) are selected to prevent interference between the multiplexed sensor output signals from the various sensors. The optical path lengths through the sensors (404, 406) and receivers (418, 420) are structured so that each receiver (418, 420) produces a phase difference signal relating to conditions affecting light transmission through a specific sensor (404, 406). A phase and amplitude modulation technique is disclosed for providing heterodyned output signals from the dristributed sensor system.

Abstract: A method and apparatus for locking the frequencies of a number of first beams of coherent radiation from respective sources (17) are disclosed. Typically, the sources (17) will form local oscillators in respective transmitters (1). The apparatus comprises a reference beam generator (10) such as a HeNe laser which generates a primary reference beam fed to an interferometer (12) which generates a second, reference beam composed of a number of reference frequencies. This second reference beam is caused to interfere with each of the beams from the local sources (17) in an optical coupler (16) and the resultant beam is detected with a photodiode (22). The electrical output signal of the photodiode (22) is filtered and fed to a discriminator (25) which controls the frequency of the local laser (17). The discriminator (25) controls the laser (17) to maintain the relationship between the frequencies of the laser (17) and the reference laser (10) substantially constant.

Abstract: A magnetic field applicator to heat magnetic substances in biological tissue, having a magnetic yoke with two pole shoes across from each other and separated from each other by a distance that defines the magnetic field exposure volume produced by the applicator, and with two magnetic coils, one assigned to each of the two pole shoes, to produce a magnetic field. The magnetic yoke and the pole shoes consist of ferrite segments assembled together. The pole shoes oppose each other and are surrounded by magnetic disk-shaped coils with one or more windings extending helicoidally, which creates an intermediate air gap between the pole shoes and coils. This results in a magnetic field applicator with the ability to effectively and efficiently administer hyperthermia and thermo-ablation procedures to destroy cancerous tissue in a patient, as well as having uses in other medical and industrial applications.
