Abstract: Docket 75-49 PATENT APPLICATION of Thomas Gerald Maxon, Jr. and James Francis Reynolds for BROADBAND MICROWAVE BIAS NETWORK     ABSTRACT            For supplying a bias (modulation) signal, either AC or DC, to a microwave circuit, a network consisting of a low pass filter is provided which presents a high isolating impedance to an extremely wide bandwidth of microwave frequencies, while allowing low frequency bias or modulating signals to be supplied to the microwave circuit without significant attenuation.  The network consists of two helical inductors, one within the other, plus a bypass capacitor.  The inner small inductor presents a high, non-resonant impedance to high microwave frequencies and the outer, larger inductor presents a high impedance to lower microwave frequencies.  The bypass capacitor cooperates with the outer inductor to complete the filter circuit for the lower microwave frequencies.  The smaller inductor's proximity to and within the larger inductor provides a distributed shunt capacitance to ground so as to terminate the filter for the higher microwave frequencies at the smaller inductor.

Abstract: ABSTRACT An improved method for forming wiring channels in a concrete floor.  Parallel trenches are formed in a concrete floor slab when the slab is poured.  A metal cover placed over each trench has a metal U-shaped channel attached thereto for dividing the trench into at least two and preferably three separate wire raceways with the center raceway completely shielded by the channel and cover.  Access boxes are selectively positioned over knockouts in the cover plate.  Metal channels are positioned to extend perpendicular to the trenches for forming main distribution ducts.  A concrete surface is then poured over the slab to extend flush with the tops of the access boxes and the main distribution ducts and a cover plate is attached to enclose the main distribution ducts.  The resulting floor structure has embedded therein parallel wiring raceways spaced across the floor with spaced accesses into each raceway and main distribution ducts interconnecting the parallel raceways.  If desired, concrete floor slabs with trenches and metal covers may be prefabricated for later use in constructing buildings.

Abstract: ABSTRACT OF THE DISCLOSURE        An input/output system couples to a host processor through a system interface unit and includes at least two input/output processing units and a memory unit.  The system interface unit includes interrupt processing logic circuits for each input/ output processing unit for processing interrupt requests on a priority basis.  The system interface unit further includes a processor intercommunication network which connects to each of the interrupt processing logic circuits.      The input/output operating system initiates an input/ output operation in response to a connect interrupt generated by the host processor executing a connect instruction.  The interrupt is directed to an assigned input/output processing unit by the System Interface Unit (SIU).  The assigned pro-cessor executes an instruction sequence which causes an appropriate entry to be places in an operating system queue located within the memory unit.  The queue entry has sufficient data to specify the desired I/O operation.  The processing unit in control stores information in the memory unit to specify the interrupt priority level of the connect operation, sets an interrupt request at that same priority level, and causes an interrupt at a very high priority level for the other processing unit via the intercommunication network.  The high priority level interrupt causes the other processing unit to execute instructions which load the priority level information from the memory unit and set an interrupt request at the specified level.  With both processing units having outstanding interrupt request at the specified priority level, the pro-cessing unit which completes all of the processes at priority levels higher or equal to that of the queue entry responds to the interrupt first.  By having the least busy processing unit respond to the interrupt utilizing the queue entry to initiate the desired input/output operation process, a balance in the utilization of the input/output processing units is insured.

Abstract: Abstract of the Disclosure There is disclosed a coin wrapping machine in which coins of a particular denomination are fed into a hopper from which they are conveyed to a coin count module. The coin count module ejects the coins one at a time, counting them as they are ejected, until a predetermined quantity has been reached. The ejected coins are directed to a stationary, removable coin tube having a central bore whose diameter is sized for the particular denomination of coins. Paper from a roll is fed to the coin tube to sur-round the stack of coins formed in the tube and a wrapping roller is brought to bear to wrap the paper about the coin stack. Crimper blades are extended into the coin tube and actuated to crimp the ends of the paper tube formed about the coin stack. The completed coin roll is dropped through an opening in a floor upon which the coin tube is seated, and the discharge of a roll is sensed by a door in a dis-charge chute. The discharge chute also detects the pre-sence of loose coins indicating an improper roll having been formed. The opening in the floor is normally closed by a coin pad, and a coin stool extends through the pad to support the bottom of the stack for positioning of the stack and to vibrate the stack to assist in settling of the coins. The operation is continuous, and is triggered by the discharge of a roll. The machine is set up for a different denomination of coin by adjusting the coin count module, replacing the coin tube with one sized for the new denomination, and replacing the paper roll with paper sized for the new denomination.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved optical system is disclosed for rapid, accurate spectral analysis of the   reflectivity or transmissivity of samples.  A concave holographic diffraction grating oscillated at high speed is utilized to provide a rapid scanning of mono-chromatic light through a spectrum of wavelengths.  The grating is positively driven at very high speed by a unique cam drive structure comprising identically shaped conjugate cams.  The rapid scan by the grating enables the reduction of noise error by averaging over a large number of cycles.  It also reduces the measurement time and thus prevents sample heating by excessive exposure to light energy.  A filter wheel having dark segments for drift correction is rotated in the optical path and is synchronous with the grating.  Source optics is employed to optimally shape the light source for particular applications. The system optics further includes a unique arrangement of lenses, including cylindrical lenses, to obtain the best light source shape which results in maximum light throughput.  Fiber optics are also employed and arranged to meet the optimum requirements of the system for light collection and transmission through portions of the optical system.

Abstract: Docket 6352 INTERLACING RECORDER                Abstract Of The Disclosure A jet drop recorder has a plurality of print heads, which print contiguous bands of graphic matter upon a sheet of printing material mounted on a rotary support.  Each print head projects a row of spaced jets toward the printing sheet, and the jets print non-contiguous spiral tracks on the sheet.          The individual jets are so spaced relative to the track width that the combination of paper rotation and advancing movement of the print heads causes side-by-side overlapping or inter-lacing of the spiral tracks.  Thus each print head prints a steadily widening solid band.  The heads each have the same number of jets and the same jet spacing so as to achieve identical track interlacing patterns.  The distance between the print heads is adjusted such that the full width printed bands interlace at their edges.  This prevents printing of an unsightly seam along adjoining boundaries of two adjacent bands.
