Abstract: Feldy-Stephens - 3-2 STEPPING MOTOR CONTROL CIRCUIT                 ABSTRACT OF THE DISCLOSURE    A stepping motor is described having two operative modes, the first mode being a normal rotary mode and the second a stationary mode.  during rotary operation, the induced energy created by interruption of the current flow through the energized phase winding is dissipated quickly by a zener diode connected across the winding.  In the stationary mode, a pulsed current is fed to one of the phase windings of the motor to assure stationary position-ing of the rotor.  During stationary operation, the zener diode is shunted with a second conventional diode provid-ing a low impedance path to the current induced in the phase winding upon de-energization.  This low impedance path greatly reduces the energy dissipated during the off condition of the pulsed current thereby greatly reducing motor power requirements during stationary operation.

Abstract: Abstract of Disclosure An indicator which is suitable for measuring a body temperature has a generally planar member shaped for retention against a very small outer surface of a body.  A temperature-sensitive material is visually activatable within a predetermined temperature range.  The temperature-sensitive substance emits, reflects or refracts visible radiation to indicate the temperature.  The color sequence in normal white light progresses from tan through red, green and blue and ultraviolet on temperature activation, the color red normally being the first easily visible response when the temperature reaches its responsive range.  Thereafter, the color falls off and tends to remain n blue color after the temperature moves above the activation range.  An optical filter visually blocks out the blue color to limit the response to the active range.

Abstract: ABSTRACT OF THE DISCLOSURE        A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex copy mode, wherein sheets are fed from a selected sheet stack one at a time, to the copier's transfer station, by a sheet feeding means which includes a combing wheel. The combing wheel shingles the leading edge of the stack's top sheet to an open feed roller nip, to be sensed there by a pneumatic sensor.  Sensing of this leading edge causes the combing wheel to be lifted off the stack.  Subsequently, at a time determined by the crpier's control logic, the drive nip closes to thereby feed the top sheet to the copier's paper registration gate, and then to its transfer station.  As soon as this sheet's trailing edge has cleared the pneumatic sensor, and the drive nip has opened, the next sheet is staged at the shingled position, in the open drive nip.  Side-one copied sheets, of intended duplex copies, are auto-matically stacked in a duplex bin.  The bottom of the duplex bin includes a flat, resilient bottom-of-the-bin pad.  This pad's position is adjustable in a plane parallel to the bottom of the duplex bin, to facilitate control of the direction in which side-one copied sheets are fed out to the copier's paper registration gate, for side-two copying.

Abstract: DISTRIBUTED PRIORITY RESOLUTION SYSTEM                  ABSTRACT OF THE DISCLOSURE      Multiple stations exchange information without central supervision.  Stations requiring a cycle of access time on a shared time-divided bus participate in a cyclic access resolution process.  The station having highest priority for a next bus cycle indicates its precedence to the other stations, and assumes exclu-sive use of the bus in the next cycle.  The bus may comprise separate sections for data and response com-munications.  Separate access resolution processes are conducted relative to each section.  After gaining ac-cess to the bus for one cycle of data transfer a sta-tion becomes ineligible to compete for access to the data section until it receives an associated response. Accordingly receiving stations may control both the rate of data transmittal and the rate of access com-petition activity at associated origin stations.  The data and response communications may include address information for enabling stations to intercommunicate directly in pairs.  Data processing stations subject to multi-level interruption may present control sig-nals designating acceptable interruption priority levels.  Other stations seeking to interrupt such pro-cessing stations are eligible to compete for access to the bus only if assigned interruption priorities are at designated levels.

Granted: 1980-04-22
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to the manufacture of fibrous wool by the rotary process.  In the rotary process heat softenable material, such as molten glass, is supplied to a centrifuge wherefrom streams of said heat softenable material emanate and are acted upon by a fiber attenuating high velocity gaseous medium located about the periphery of the centrifuging means.  As a result thereof, a cylindrically shaped veil of high velocity gases having attenuated fibers contained therein flows axially away from the centrifuging means to a suitable collecting means.  By the present invention improved method and apparatus are provided for distributing the entrained fibers upon the collecting means.  The cylindrically shaped veil is intermittently acted upon by finite planes of high velocity gas thereby interrupting the otherwise columnar flow of the cylindrical veil and establishing diverging flows of fibers.  By the intermittent action of the gaseous planes upon the cylindrical veil a randomly uniform distribution of fibers upon the collecting means is realized.
