Title: Method for developing thick beds of minerals
Inventor: TRIPOLKO ALEXANDR S
IPC: E21C41/16
Filed: 1991-07-15
Granted: 1998-05-05
Abstract: A method for developing thick beds of minerals accomplished by large-section rooms, comprising preparation of the room for winning which consists in executing a conveyer working below the soil of the room tothe entire length thereof, driving transport and fan drifts and raises, inclined working to fit the design contour of the room. The winning is effected in horizontal layers in a descending order by forward and reverse movements of the cutter-loader, each said layer is developed by stopes throughout the entire length of the room overlapping the cutter-loader movements. The first stope in each layer is developed in the range of raises, and subsequent - in the direction from the first stope toward the eges of the room.  Extraction of subsequent layers starts from the soil of the preceding layer by deepening the cutter-loader to a layer underneath to the height of its actuator. In the end part of the room within the limits of one stope there is formed an inclined descent to a layer below which is then suppressed while developing this layer opened by this descent.  The inclined working is opened in each layer by developing extreme movement.  The mineral is upplied to the raises and passed to the conveyer working.

Granted: 1999-09-28
Abstract: Diene polymers or copolymers having improved raw polymer viscosity, good processability in carbon black reinforced stocks and reduced hysteresis in the cured and carbon black reinforced state are provided. These diene polymers or copolymers comprise a mixture of diene polymer or copolymer chains containing carbon-tin bonds in the main polymer or copolymer chains and diene polymer or copolymer chains containing terminals derived from vinyl-compounds containing heterocyclic nitrogen groups.

Abstract: A novel pneumatic tire is provided herein. The tire includes a tread portion, a pair of axially-spaced bead portions, a pair of sidewall portions extending between tread edges and said bead portions and a pair of bead cores, each bead core disposed in an associated one the bead portion. A carcass extends between the bead portions through the tread portion and the pair of sidewall portions. A belt is disposed radially-outside the carcass and extends across the width of the tread. Each sidewall portion is provided axially-inside of the carcass with an inside sidewall rubber layer, the inside sidewall rubber layer extending radially-inwardly to the bead portion and radially-outwardly into the tread portion along a convexly-curved inner surface of said carcass. The total thickness of the tire measured from the outer surface to the inner surface of the tire satisfies the condition that the total thickness (TA) is substantially-constant in a region (8), the region S being defined as extending between a maximum width point (A) at which the maximum width of the tire lies under an unloaded state, and a 65% height point (B) located at a 65% height (HB) of the tire section height (H), each being measured from the bead base line (b) under the unloaded state.      The unloaded state is such that the tire is mounted on its regular rim and inflated to its regular inner pressure but is loaded with no tire load. The total thickness (TC) measured at a contacting point (C) is larger than the total thickness (TA) in the region (S). The contacting point (C) is defined as a point at which the outer surface of the tire starts to contact with the radially-outer edge of a flange of the regular rim under the unloaded state.

Title: Rail lubrication application system
Inventor: SZATKOWSKI JAMES GERARD
IPC: B61K3/02
Filed: 1993-03-09
Granted: 1999-09-14
Abstract: A lubrication applicator presses a block of solid lubricant against the flange of a locomotive wheel. An applicator nozzle loosely fits over the body of the applicator and lightly engages the block of lubricant to bridge the gap between the body and the wheel. The applicator is supported by a main bracket fixed to an unsprung portion of the locomotive truck, such as a journal box or a traction motor, and an adjustable bracket which establishes a good attitude of the applicator and is movable radially of the wheel to accommodate wheels of different diameters. A bracket attached to a journal boat fits in a restricted space between the truck frame and the wheel and comprises a plate with upper and lower channels attached to opposite sides to provide strong and light structures subject to minimal inertial loading in a severe vibrational environment. To lessen the inertial forces the brackets angle upward (rather than horizontally) to position the applicator within about 45° of the vertical plank of the wheel.

Filed: 1993-09-23
Granted: 1998-06-23
Abstract: A vehicle restraint system includes restraint means positioned in a vehicle to restrain motion of an occupant upon operation of the restraint means.  An impact sensor includes means for sensing vehicle impact of non-magnetic construction having an internal cavity, a permanent magnet movably mounted within said cavity, means for resiliently urging the magnet to a first position within that cavity, means for sensing motion of the magnet within the cavity against force of that urging means to generate an impact signal, and means responsive to that impact signal for operation of the restraint means.  The motion-sensing means comprises a Hall sensor that provides the impact signal as an analog electrical signal having a magnitude that varies as a continuous monotonic function of position of the magnet within the cavity, and the signal-responsive means includes means for analyzing rate of change of that analog electrical signal and for operating the restraint means when that rate of change indicates a vehicle impact condition.  The system can include means for selectively testing operative condition of the impact sensor and means for disabling operation of the means for operating the restraint means during testing of the impact sensor.  The system also can include a light emitter at the sensor responsive to the electrical signal to provide a light signal, a light sensor at the signal-responsive means for reconverting that light signal into an electrical signal, and a fiber optic connecting the light emitter to the light sensor.

Title: Multi-level conference management and notification
Inventor: GALLAGHER DONALD DEAN
IPC: H04M3/56
Filed: 1993-10-19
Granted: 1997-09-16
Abstract: A multi-level conference in which an originator of telephone conference of the multi-level conference controls the parties that can be added to that conference and can terminate any party at any time. Further, if two existing telephone conferences are combined together to form the multi-level conference, the party that originated the combining of these two conference calls can control not only the parties on its conference call but can disconnect all of the parties on the second conference call. In addition, the control of the conference resides in the telephone terminals beingutilized by the participants, rather than in a centralized service computer. Information concerning the conference and control of the conference is communicated between the telephone terminals utilizing the standard telecommunication communication control channel and does not require the establishment of a separate data call to a centralized service computer. In addition, the telephone terminals display the names and telephone numbers of parties on the multi-level conference and identifies parties controlling the individual conferences. In addition, when two conferences are combined together, each originator of a conference maintains control over their subconference and can independently separate that subconference from the other conference in a multi-level conference.

Abstract: Jettisonable sabot for a subcaliber projectile.   In a jettisonable sabot for a subcaliber projectile, which is fired from a weapon barrel having helical grooves, there is a risk that  individual  segments  of  a  sabot  body, strike  the projectile body with their edges during the separation from the projectile body, with these impacts against the projectile body impairing the impact accuracy. In order to avoid these impacts, the parting planes or slots between the individual segments of the sabot body are not arranged radially, as in the past,  but rather parallel with radial planes with a specified distance (d) corresponding to at least half of the radius (R) of the projectile body, with the slits between the segments  of  the  sabot  jacket  preferably  being  arranged parallel to radial planes with a specified distance (d).
