Abstract: EDUCTOR APPARATUS HAVING A VARIABLE ORIFICE ANNULAR VENTURI NOZZLE FOR VACUUM CIRCULATION IN DRILLING SYSTEM          Abstract of the Disclosure.  A drill system uses double walled concentric pipe and a drill bit attached at one end of the drill pipe and a power swivel at its upper end having means for applying compressed air to the outer annulus within the drill pipe and means for attaching a vacuum line to the center annulus of the drill pipe.  A flexible hose attached to the vacuum portion of the drill pipe has an  eductor assembly using compressed air to create a vacuum to remove the cuttings during the drilling operation.          The  eductor assembly includes an annular nozzle surrounding a straight-through bore providing an obstruction-free passage for induced air and drill cuttings.  Motivating air flowing through the nozzle passes through flow restriction, then diverging diffuser, to accelerate air to supersonic velocity.          Means are provided to vary the nozzle orifice in response to changes in the pressure of the motivating air to optimize the pressure drop across the orifice and thus compensate for varying air volume flow rates.  A diverting valve, having its input connected to pressurized air from an air compressor, has one output connected to the input of the eductor and its other output connected to the outer annulus portion of the drill pipe.  The diverter valve provides the operator the ability to pressure reverse circulate, to vacuum reverse circulate, or an infinitely variable combination of the two.     -1a-

The second jaw presses the cable onto the support when the jaws are in closed postion, to make the cutting means protrude beyond the support to a selectively adjustable extent to effect the incision to a predetermine depth.  A gripping means associated with one of said jaws is then used in effecting the relative rotation to complete the cut.

Abstract: ABSTRACT OF THE DISCLOSURE The accuracy of monitoring a process involving heat exchange, as in the case of monitoring the "instantaneous" power output of a nuclear reactor may be improved by reading the steady state rate from the heat transfer indicated by the coolant, and obtaining a second reading representative of the rate of change in power level, using a neutron flux read out from one or more selected reaction zones to provide a fast response value for the rate of change.  Integration of this rate value gives an accurate value for the extent of power rate change, which can be added to the first, steady state thermal read out, to give a power reading of short response time and acceptable accuracy.  The dynamic error resulting from the flow time of coolant in passing through the process is also corrected by introducing a time delay allowance  which reduces the coolant quantity and temper-ature parameter readings to a common datum.

Abstract: Abstract of the Disclosure An optical fiber waveguide is disclosed wherein germanium dioxide (GeO2) and phosphorus pentoxide (P2O5) are radially graded in the core of the optical fiber for the purpose of achieving minimum modal disper-ion over a broad range of wavelengths.  The phosphorus pentoxide has its maximum concentration on the axis of the fiber core and is graded to zero concentration at the core-cladding interface.  The germanium dioxide has its maximum concentration at the core-cladding interface, is constant throughout the cladding and is graded to zero concentration on the axis of the fiber core.  The ratio of maximum P2O5 to maximum GeO2 is approximately 11.6 and therefore the numerical aperture is only slightly degraded as a result of the reverse doping of germanium dioxide.
