Abstract: The known techniques for controlling the speed of revolution of electric drives are not suitable or too costly for a control of the entire speed of revolution range which is of practical interest in laboratory centrifuges. According to the invention, a rotary current drive is proposed whose speed of revolution control is based essentially on a Y-delta change-over in conjunction with a voltage and frequency conversion. The synchronous speed of revolution is automatically controlled and the Y-delta change-over activated as a function of a preselected speed of revolution, a speed of revolution control range which comprises both low-speed and high-speed laboratory centrifuges or other small centrifuges being obtained in conjunction with the load characteristic of the respective centrifuge rotor by combining these techniques. Thus, all the practically relevant speed of revolution ranges of such centrifuges can be covered in an economical manner with an electric drive. <IMAGE>

Abstract: A document handler (20) for presenting documents to the platen (23) of a copier (10) for copying with a document transport system (32) having document-transport belts (35) movable under a substantially-planar background surface (33a) overlying the platen, and a suction system (33) for applying a partial suction to a document sheet being transported by the movable belts over the platen; with a clamping and unclamping system for moving the background surface against the platen to flatten the belts and a document thereon against the platen for copying. During unclamping, the surface lifts slightly away from the platen, while the document is retained on the belts by suction, by first lifting one edge of the surface 33a up away from the platen substantially before the opposite side, and then subsequently lifting the opposite side, to generate a controlled air flow across the face of the document to retain it on the belts, and moving the belts when the surface is lifted away from the platen. During clamping the one side of the surface 33a moves towards the platen, beginning slightly before the opposite side, to generate a controlled expulsion of air. The disclosed system has two pairs of commonly rotatably driven cams (60, 60a, 62, 62a) with different cam rise times connected to lift the one side of the clamping surface with a motion different from that of the opposite side. The cams can first lift the one side about 2.5 mm, while the opposite side remains in contact with the platen, then lift the opposite side about 0.8 mm, and then the clamping surface can be leveled by lifting the opposite side to about 1.75 mm while the one side is dropped to about 1.75 mm.

Abstract: A superfluorescent broadband fiber laser source comprises a fiber doped (108) with laser material coupled to a multiplexing coupler (104). In the preferred embodiment, a source (100) of pumping illumination provides pumping light to the doped fiber (108), and the coupler (104) is adjusted to have a 0% coupling efficiency at the wavelength of the source (100). The pumping light is sufficiently intense to produce amplified spontaneous emission within the doped fiber (108), and gives rise to a forward signal and a backward signal. One of the superfluorescent signals is reflected back to the doped fiber (108) by a reflector (118) cemented to one end of the doped fiber (108) or to one end of another fiber through the coupling function of the coupler (104). The coupler (104) is adjusted to provide complete coupling at the frequency of the lasing light. The temperature dependence of the coupler (104) can be selected to reduce or cancel the temperature dependence of the superfluorescent signal. Other arrangements utilizing the mutliplexing properties of the coupler (104) are also described. An all-fiber reflector can also be used.

Abstract: A field-based movement sensor adapted for measuring strain along a certain axis in an object on which the sensor is attached. The sensor includes a substrate having a working surface and formed with a pair of fingers projecting from a first direction, and a third finger projecting from a direction opposite the first direction, to a position between the pair of fingers. The pair of fingers and third finger extend generally perpendicular to the axis along which strain is to be measured, with the pair of fingers being moveable with respect to the third finger along the axis when the strain occurs. An electrically charged element for producing an electric field is disposed on the working surface of the third finger, and a pair of field-effect transistors (FETS) are each disposed on a working surface of a different one of the pair of fingers. As the object is subjected to strain causing the pair of fingers to move relative to the third finger, the variations in the strength of the electric field from the charged elements to the FETS is determined and this provides a measure of the variation in distance between the third finger and the pair of fingers and this, in turn, provides a measure of the strain in the object to which the substrate is attached.
