Abstract: ADDRESS TRANSLATION CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE Disclosed is an address translation control system comprising an address translation buffer having a plurality of entries each including at least a valid flag, a logical address field, and a physical address field, a memory array having copies of at least the valid flag and the physical address field, and a purge register for storing information showing a portion of the contents of the address translation buffer to partially purge the address translation buffer. When the coincidence between the physical address of the address translation buffer and the contents of the purge register does not occur, the ordinary access processing can be carried out, and when the entry of the memory array is accessed in turn and the coincidence between the physical address in the memory array and the contents of the purge register occurs, the partial purge is performed by clearing the valid flags of the corre-sponding entries of the address translation buffer and the memory array. Thus, the partial purge processing can be carried out separately from the ordinary access processing, and the application efficiency for the address translation buffer increases. Particularly, the performance efficiency for the application of this invention to a pipeline system or a virtual machine can be increased.

The ingredients include corn kernels having a moisture content of about 11.5 percent or more and the peelable seal has sufficient strength to remain closed for at least one-half of the time required to pop substantially all of these kernels.  The top edge seal opens before popping is completed to release steam and prevent the popped corn from becoming too chewy.

Abstract: 51,450 ABSTRACT OF THE DISCLOSURE         A sludge lance nozzle for removing sludge from between the tubes of a nuclear steam generator includes positioning apparatus mounted on top of the nozzle.  The positioning apparatus includes a cylindrical eddy-current sensor mounted inside a cup-shaped non-magnetic electric-ally  insulating  spacer,  which is in turn mounted in a cup-shaped support member fixedly secured to the nozzle.          The tubes are arranged in rows and columns with the axes of the tubes in each column  lying in a  common column plane.  The nozzle is moved perpendicular to the column planes close to one of the rows of tubes.  The  sensor produces a maximum-amplitude output signal when the sens-ing axis is coplanar with the column plane of a tube in the closest row of tubes and a minimum-amplitude output signal when the sensing axis is midway between adjacent tubes in the closest row of tubes.

Abstract: ABSTRACT           Apparatus for grinding twist drills comprises a drive shaft and a grinding wheel, which is coupled to said shaft and is mounted thereon to be axially movable relative to the shaft and is spring-loaded toward a drill-guiding structure facing the grinding surface of the grinding wheel.  The drill-guiding structure comprises guiding passages for guiding drills differing in diameter against the grinding surface and in association with each guiding passage comprises at least one guide lug for extending into a flute of the twist drill extending through the associated guiding passage, and a drill stop for limiting the advance of the twist drill in the guiding passage against the elastically yielding grinding wheel.          To said drlll-guiding structure at least one abutment is connected which is engageable by the grinding wheel and has a higher  ?       hardness than the grinding wheel.  That abutment has an abutment surface which is parallel to the grinding surface of the grinding wheel and is engageable by said grinding surface to limit the displacement of the grinding surface toward the drill-guiding structure under spring force in an end position in which the grinding surface is closer to the guide lugs than the drill stop.  The provision of said abutment ensures that the wear of the grinding wheel will not change the position of the grinding wheel relative to the drill-guiding structure and that the grinding surface will be restored substantially to its original shape when the grinding surface has been subjected to irregular wear.

Abstract: ABSTRACT OF THE DISCLOSURE     A paper is a unitary structure but has more than one layer.  The layers are of respective different fibres. The paper is made by applying a second slurry to a first slurry at a time when both layers have a consistency which is primarily liquid but the first is less liquid than the second.  The second slurry is applied to the first so as to provide a disturbance at an interface between the surfaces of the layers.  This application of the second slurry is carried out under predetermined conditions of angle, distance, rate and consistency having regard to the conditions of the first slurry when the second slurry is applied so as to control the extent of disturbance in the interface between the layers and hence the degree of intermingling and interlinking in the interface region.  This ensures the bonding together of the layers irrespective of the nature of the material of the slurries.      The process allows the strength of the paper at the interface to be at least as great as that in either of the two layers.  Thus this process is particularly suitable for forming a battery separator or a gas-cleansing filter.

Abstract: METHOD OF MEASURING LEAK RATES                    ABSTRACT OF THE DISCLOSURE           An improved method of measuring leak rates by placing a source of fluid pressure in communication with a cavity being tested, and measuring the flow rate to the cavity after a predetermined time to determine the leak rate from the cavity.  The improved method achieves a determination of the leak rate in a shorter time than that required to establish steady state flow conditions between the pressure source and the test piece cavity.          The improved method measures the flow rate to the test piece cavity at a much earlier time after pressurization of the cavity than normally required to establish such steady state conditions, and applies a previously generated calibration function based on a linear correspondence between the measured flow rates and the steady state flow rates.  Flow rate measurements at the earlier time in the test cycle in regular testing of testing pieces are converted to steady state flow rates by application of the calibration function to substantially shorten the time required for leak rate testing of the test pieces.

Abstract: Abstract Of The Disclosure A fingerprint image is derived from the direct optical reading of a finger by an optical and electronic scan of the finger with a beam of coherent, collimated light.  The beam is shaped in the form of a slit of light which extends the length of the finger zone to be inter-rogated.  That slit light beam is scanned across the finger in a direction perpendicular to the axis of that slit.  The rays which constitute the interrogating light in the slit define an incident light beam in the form of a plane which is substantially perpendicular to the surface of the finger being interrogated. The light beam and the rest of the optical system is rotated about an axis that is substantially coincident with the axis of the finger so that this perpendicular relationship be-tween the plane of the interrogating light beam and the surface of the finger is maintained throughout the scan.
