Abstract: The invention concerns a multi-wavelength pyrometer for the measurement of the temperature and emissivity of a surface above 900 K. The pyrometer has several radiation detectors sensitive in different wavebands  lambda 1...  lambda i...  lambda n as well as a data processor to which the detector outputs are fed after digitalization and which calculates the temperature of the surface from these detector outputs using Wien-Planck's law, assuming the surface is a perfect black body. The emissivity is then calculated, as a function of the temperature and the wavelength, from these calculated temperature values using an approximation method, and from this, the required temperature. The invention calls for the differences between the actual pyrometer signals and the signals which would be expected from the assumed emissivity and the temperature calculated from this emissivity to be determined for various approximations and various wavelengths. The approximation which gives, for all the wavelengths, the least sum of the squares of these differences is then selected.

Abstract: An electric motor is disclosed including heat spikes (36) within the stator slots (34). The heat spike (36) extend radially inward from the stator back iron into the slot (34) between the stator teeth (32). The heat spikes (36) placed within the stator slots reduce the heat path length and increases the heat transfer areas to the iron. Together, these allow the winding heat to dissipate quicker and, at the same time, reduce the winding hot spot temperature and improve the motor's load rating.

Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object (4) includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member. The apparatus also includes an elongate, flexible band (8) capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object (4) whose displacement is to be measured is moved. The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object (4).

Abstract: A disposable pricker has a two part body with the parts connected by a hinge (6). A spring (10) and a lancet (1) are entered in one tubular part (7) which is then hinged to a ready position in which the leading end of the lancet; projecting from the tube (7), is confined by a guide (17,22) on the other part. The tip (4) of the lancet is protected by a cap (5) which is removed before or as the two parts (7,11) are hinged closely together. This takes the leading end of the lancet clear of the guide (17) and into a passage (13) with a restricted mouth (14). The spring (10), which may be energised at the ready position or by the guide (22) wedging the lancet (1) back, can then act to shoot the lancet (1) forward to cause momentary projection of the tip (4) through the mouth (14). Retraction is assured by the spring (10) or resilient tabs (21) at the mouth.

Date Jun. 27, 1991.The transmission equipment includes a plurality of subscriber nodes which are connected serially to an optical fiber. Every node comprises an access unit with at least one directional coupler, an address detection unit, a receiver, a synchronization unit, as well as a control unit with a switching transmitter. Addressed packets continuously reach the nodes and pass through the latter via the fiber in the form of modulated light. In a first switching position, the directional coupler branches off a part of the light power of the packets from the fiber, converts the light in the optoelectrical transducer into electrical signals and reads the respective packet address in the detection unit. If this packet address matches the address of the node the control unit switches the directional coupler into a second switching position. The coupler branches off another part of the light power of the packet in this second switching position and, in so doing, feeds the occurring electrical useful signals to the receiver. The first and second switching positions differ in that a considerably greater proportion of the respective light power is branched off from the fiber in the second position than in the first switching position.

Abstract: A description is given of a method and an apparatus for guiding a continuously moving tow in synthetic fibre manufacture. In this case, the profile (the thickness distribution and width) and the position of the tow are sensed continuously in a contactless fashion, and a corresponding electric signal is generated. This electric signal is used to control the profile and the position of the tow in such a way that the profile and position remain within prescribed set value ranges. A CCD camera (12) is preferably used to sense the tow geometry, while the control of the tow geometry is performed by deflecting means (16) engaging the tow. It is possible in this way to optimise the profile and position of the tow, for example for the entry into a crimping chamber (8). …<IMAGE>…
