Title: Melanin-based agents for image enhancement
Inventor: WILLIAMS ROBERT F
IPC: A61K51/08
Filed: 1992-04-15
Abstract: The present invention involves an image-enhancing agent comprising paramagnetic melanin combined with an essentially non-dissociable signal-inducing metal. The signal-inducing metal has an association constant for its melanin combination of at least about 1020. Upon suspension or dissolution in water the metal remains undissociated. A preferred signal-inducing metal is paramagnetic or superparamagnetic, of course for magnetic resonance imaging.  Preferred paramagnetic or superparamagnetic metals are gadolinium, iron, nickel, copper, erbium, europium, praseodymium, dysprosium, holmium, chromium or manganese. Gadolinium is the most effective metal. The metal is incorporated into the melanin in an ionic or particulate form. Metals may be utilized which are particularly useful to modify ultrasound images by the enhancement of the image obtained from emission and detection of high-frequency soundwaves. Metals emitting gamma particles may also be utilized to enhance images resulting from gamma particle emission scanning.  51Chromium, 68gallium, 99mtechnetium and 111indium are preferred metals for gamma particle scanning. Additionally, native or synthesized melanin, in and of itself is an effective MRI  image-enhancing agent because of the ability to control the free radical content of the melanin polymers.

Abstract: A fairlead mechanism for guiding a dragline drag rope includes a support on the chassis of the dragline and a guide mechanism mounted on the support.  The guide mechanism includes at least one pair of guide sheaves each having an annular groove.          The guide sheaves are rotatably mounted on the support to present the grooves in facing relation to define between the sheaves a guide path through which the drag rope passes in primary frictional contact with at least one of the guide sheaves to cause the contacted guide sheave to start-stop cycle between rotating and nonrotating modes as the drag rope reciprocates during operation of the machine.  The fairlead mechanism further comprises a synchronizing mechanism utilizing gears or belts for causing the pair of guide sheaves to simultaneously stop or counterrotate in unison in response to rope contact with either one of the guide sheaves to minimize wear that would be induced by scrubbing between the rope and the guide sheaves.

Title: Removal of hydrogen sulphide
Inventor: CLAPP PHILLIP A
IPC: B01D53/86
Filed: 1992-07-20
Abstract: Hydrogen sulphide can be removed from a gaseous stream by contact with a 2,3-dialkyl substituted naphthoquinone in the presence of a catalytic amount of an amine catalyst dissolved in a hydrophobic organic solvent system, with consequential formation of a corresponding quinhydrone and insoluble elemental sulphur. Preferably the total number of carbons in the alkyl substituents is from 2 to 6. Particularly suitable compounds comprise dimethyl and/or ethyl/methyl naphthoquinones. Preferably the amine catalyst has a pK in the range of about 9 to 11.5. Preferred solvent systems comprise mixtures of aromatic hydrocarbons with aliphatic esters such as methyl cyclohexanol acetate or dialkylketones such as diisobutylcarbinol. Advantageously, the naphthoquinones react with hydrogen sulphide significantly faster than do the anthraquinone or tetrahydroanthraquinone compounds hitherto proposed. The insoluble sulphur can be recovered as product and the resultant solution containing a reduced species, believed to be naphthoquinhydrone, can be contacted with an oxygen-containing gas for generation of hydrogen peroxide and reformation of the naphthoquinone. After extraction of the hydrogen peroxide with water, the organic solution is available for contact with further hydrogen sulphide.

Title: Transparent inband signaling
Inventor: PROHS JOHN R
IPC: H04M3/523
Filed: 1992-07-28
Abstract: A method and apparatus for transparent inband signaling during a telephone conversation provides an advantageous way of enabling a party to a telephone conversation to signal a telecommunications system to perform desired functions. A person signaling a system with a generated inband signal, such as DTMF, can do so transparently, that is without the other party hearing the inband signals used. This innovation is based on detecting the inband signal (65A) muting the inband signal (65C) to prevent the other part from hearing it, and determining which party generated it while allowing the conversation to continue substantially uninterrupted. In an alternate method and apparatus, the inband signal is delayed (71A) for a short period of time in order to compensate for the time delay in reliably detecting DTMF signals and thus mute the inband signal more completely.

Title: System for grouping and conveying continuously arriving articles
Inventor: ODENTHAL HEINZ F
IPC: B65G47/29
Filed: 1994-05-03
Abstract: ABSTRACT OF THE DISCLOSURE A handling system used with an input conveyor operating at a substantially constant input-advance speed and delivering articles one at a time at the input speed to an input station has an output station spaced from the input station and adapted to hold an upwardly open receptacle and a transfer conveyor having an upstream end at the input station and a downstream end at the output station. The upstream end is positioned to receive the articles from the input conveyor. A drive continuously advances the transfer conveyor to displace the articles in a travel direction from the input station to the output station and to deposit the articles at the output station in the receptacle. A blocking element can move between the stations between a position blocking movement of the articles from the input station to the output station and a freeing position permitting such movement. A controller connected to the blocking element periodically displaces the blocking element into the blocking position and thereby causes the articles on the transfer conveyor upstream of the blocking element to bunch up and slide on the transfer conveyor immediately upstream of the blocking element. Thus even though the input and transfer conveyors operate continuously, the articles are piled up in groups and delivered as groups to the receptacle. The handling system can easily be reconfigured to different size articles, to groups including different numbers of articles and to different size output boxes. A method of operating the handling system is also disclosed.

Title: Fibre-optic sagnac interferometer for measuring rate of rotation, comprising a wavelength-stabilized light source
Inventor: KEMMLER MANFRED
IPC: G01C19/72
Filed: 1994-08-19
Abstract: Abstract Fibre-optic Sagnac interferometer for measuring rate of rotation, comprising a wavelength-stabilized light source The invention relates to the additional use of an inte-grated optics chip (MIOC) as Michelson interferometer for stabilizing the wavelength of a light source (L) within a fibre-optic Sagnac interferometer for measuring rate of rotation,  wherein in addition to a resetting digital phase ramp (AT1) dependent on the rate of rotation also a statistically independent second signal component is applied to a phase modulator included in the integrated optics  chip  (MIOC),  said  second  signal  component optimizing the working point of the phase modulator (PM). With this type of statistically independent variation of the  phase  modulation,  the  light-wavelength-dependent measuring signal of the Michelson interferometer can be demodulated from the detector read-out signal and can be used for readjustment of the light-source wavelength via a  light-source  temperature  change  and/or  injection current change for the light source (L). In open loop operation, variations of the scale factor can be compen-sated  using  the  light-wavelength-dependent  measuring signal.             The invention provides the advantage that on the one hand the  wavelength of  the  light  source  (L)  is measured directly and that on the other hand no additional hard-ware is required due to the employment of a separate interferometer for measuring and readjusting the wave-length of the light source (L), and for controlling the scale factor, respectively.

Title: Modular pneumatic accumulation conveyor
Inventor: SCHIESSER RICARDO N
IPC: B65G47/26
Filed: 1994-08-24
Abstract: An accumulation conveyor includes a product sensor that is positioned along the conveyor at a particular zone for sensing the presence of product at that zone and for causing actuation of the zone upstream of that product sensor with respect to product movement along the accumulation conveyor. The product sensor includes an arm that is selectively positioned in the path of product being conveyed, a switch having an actuation member juxtaposed with the arm, and a force-producing member responsive to actuation of the downstream zone actuator in order to apply a force to the switch and, in turn, retract the sensor. This may be accomplished by physically locating the product sensor within the downstream zone and providing an actuator for that downstream zone that is mechanically coupled to the product sensor physically located within that zone. When the actuator is actuated, it retracts the product sensor from the path of movement of product along the accumulation conveyor concurrently with actuation of the downstream zone. The switch may be selectively mounted either to a stationary member or to the downstream actuator. If the switch is mounted to the stationary member, the associated sensing member is not responsive to actuation of the downstream actuator and a non-retractable sensor function is achieved. If the switch is mounted to the actuator, actuation thereof will retract the sensing member from the path of movement of the product along the accumulation conveyor. Thus, each product sensor may be made into either a retractable sensor or a non-retractable sensor. Each actuator includes a moveable member that reciprocates with respect to a stationary support member to which is mounted a signal manifold that interconnects with signal manifolds of adjacent control devices and with a force-producing device for reciprocating the moveable member of that actuator. The accumulation conveyor further includes a drive assembly that is entirely supported by the side rails of the accumulation conveyor in order to thereby be positionable at substantially any longitudinal location along the product conveying surface.
