Abstract: A detector 10 used to sense the presence of control markings 20 on a moving web 12. The detector responds to abrupt changes in intensity of electromagnetic radiation rather than merely to absolute intensity values. Gradual changes in or a constant level of detected radiation or detector temperature do not change the magnitude of the abrupt changes in radiation intensity to which the detector responds. This capability allows the detector to distinguish between electromagnetic radiation emitted by wavelength-shifting control marks 20 and changes in web background and/or ambient radiation. A filter 38 is interposed between a photo diode 36 in the detector 10 and the web 12 to further enhance detector performance.

Abstract: An electromagnetic relay has a hallow coil body and coil having a longitudinal axis with a bar-shaped armature pivotably mounted for movement in and extending through the coil body, a permanent magnet arrangement having polarization directions perpendicular to the coil axis, two yokes disposed in a single plain parallel to the permanent magnet arrangement, two pole plates connected to the yokes and also extending perpendicular to the coil axis, and a flux plate overlapping and spaced from the yokes and having a flat segment with the magnet arrangement being disposed in the volume defined between the overlapping area of the flux plate and the yokes, the magnet arrangement extending substantially longitudinally parallel to the coil axis. The structural arrangement of the flux plate and yokes so as to define a volume which can accommodate the magnet system permits the magnet system to be encompassed within the relay without adding to the overall length thereof, thereby adapting the relay to miniaturization. Additionally, the surfaces of the yokes and permanent magnet can exhibit a relatively large area, again without causing any increase in the length of the relay.

Abstract: The present invention relates to a method for comminuting a coarse lump mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction is determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a size distribution graph obtained by screen analysis of a grinding mill charge of material obtained after an autogenous grinding process. The smallest particle size of the coarse fraction is greater than the particle sizes in the upper of said inflexion points, and the ratio between said fractions is determined on the basis of achieving a given charge quantity for a particular, selected set-point power value fo the mill in question, and determined with respect to a selected degree of grinding.The grinding efficiency of autogenous primary grinding mills is greatly improved by means of the invention (Figure 4).

The water, acting as a heat source, is fed into a vacuum vessel and subjected to triple-point conditions thereby concomitantly forming water vapor and a water/ice crystal suspension. The evaporator is disposed in the vacuum vessel out of direct contact with the water/ice crystal suspension for absorbing heat from the evaporated water vapor.

Abstract: A seal for use around a rod electrode passing along an axis through a hole in the wall of a furnace into the interior of the furnace has an annular and at least limitedly flexible seal ring fitted snugly around the electrode in the hole and a holder carrying the seal ring and sealingly engaged with the furnace wall. Thus gas flow through the wall at the hole past the seal ring is substantially blocked. The seal assembly has structure forming with the electrode and seal ring a substantially closed chamber surrounding the electrode axially inward into the furnace from the ring. This chamber is pressurized at superatmospheric pressure with an inert gas and the electrode is cooled inward of the furnace from the seal ring. The seal ring is compressed axially by a packing assembly so it is pressed radially against the electrode. The packing includes rigid split compression rings bearing axially on the seal ring.

Abstract: An apparatus for treatment of elongated objects (51) comprises a vessel (7, 45, 46, 47, 48 and 55) in which it is arranged for a liquid bath to be maintained. Openings (36) in each of two opposite side walls (45, 46) are adjusted to the cross-section of the objects and the objects are intended to be conveyed through the bath via the openings. The liquid bath is maintained partly by pumping treating liquid from a storage sump (15) to the vessel and partly by subjecting the apparatus to a vacuum by means of a fan (4). The storage sump (15) is provided with means for level regulation (17, 19) so that an essentially constant liquid level can be maintained. The storage sump can be replaceably mounted to the vessel. According to one embodiment the vessel (7, 45, 46, 47, 48 and 55) can be provided with a housing (2, 7, 47, 48, 5) which has openings (37) in front of the respective openings (36) of the vessel. As the housing communicates with the vessel and the storage sump ambient air will be sucked in through the openings in the housing and thereby reducing foaming of the treating liquid in the apparatus will be obtained.

Abstract: The rollers or curved rods and other elements supporting the glass sheets as well as the apparatus necessary for bending and/or tempering are preferably mounted on a pair of longitudinally flexible strips that rest on a pair of rigid templates having the desired curvature. Each flexible strip advantageously is a chain whose links are hinged on one another, these links being provided with flanges to which are fastened the rollers or curved rods, all other elements for supporting the glass sheets, and the elements necessary for bending and tempering. To permit modification of the curved profile, the templates are removable and interchangeable. To facilitate changing of the templates, the apparatus is equipped with a system for lifting the strips or chains. Such lifting system comprises one or more pivoting beams that are lifted by drive means such as a jack and a bent connecting rod. When the beams are raised, they lift the strip or chain off the template, thereby freeing the template to be replaced with a template having a different curvature.

Abstract: A batteryless, portable, transponder useful in a tag for a presence detection system. The transponder detects electromagnetic radiation at a first predetermined frequency and responds to said detection by transmitting electromagnetic radiation at a second frequency that is a subharmonic of the first frequency. The transponder includes an amorphous magnetic material component (48) for storing energy from the electromagnetic radiation detected at the first frequency for transmission as the electromagnetic radiation transmitted at the second frequency. In one embodiment (Figure 9A), the transponder includes a thin, flat ribbon (48) of low coercivity magnetostrictive amorphous magnetic material having a transverse uniaxial magnetic anisotropy defining a magneto- mechanical resonant frequency "f" in accordance with the dimensions of the ribbon, when in the presence of a magnetic bias field of a predetermined intensity, wherein the ribbon responds to the detection of electromagnetic radiation having a frequency "2f" by transmitting electromagnetic radiation at a subharmonic of the frequency "2f"; and means for biasing the ribbon with the predetermined magnetic bias field. In another embodiment (Figure 1), the transponder consists of a single resonant circuit including a nonlinear inductor (L1) having a core made of amorphous magnetic material; and a capacitance (C1) connected in series with the inductor to define the resonant circuit. The core of the nonlinear inductor includes an elongated thin, flat ribbon of low coercivity amorphous magnetic material. It has been observed that this resonant circuit exhibits a bifurcated frequency-division characteristic in relation to the amplitude of the detected electromagnetic radiation at the first predetermined frequency, whereby additional frequency divisions occur as the amplitude is increased. A coded tag (Figure 10) includes two amorphous magnetic material transponders (60, 62) that detect electromagnetic radiation at different frequencies.
