Abstract: ABSTRACT OF THE DISCLOSURE         A tubular element for removing particulate matter and bacteria of dimensions in excess of a predetermined value from a fluid flowing from the interior to the exterior of the filtration element has a first inner layer of a highly porous material that has a low coefficient of sliding friction, and a second layer of a microporous filtration material having pores of substantially uniform size.  The element may include an outer support layer of a porous material that is not subject to shedding.  In a preferred form, the inner layer is formed from a high wet strength paper, the micropourous filtration layer has sufficiently small pores to remove all bacteria from the fluid, and the outer layer may be a fine porous plastic sheet material or a high wet strength, high porosity paper that is impregnated with the polymeric material that forms the micro-porous filtration material.  The fine pore structure of the outer layer supports the fragile filtration layer.  In a preferred form, both ends of the tubular element are impregnated with a suitable sealing material such as a polyurethane potting compound. The ends are preferably dipped in the sealing material to a predetermined depth.  When cured, these end portions provide additional mechanical support for the tube ends, and block the passage of particulate matter and bacteria past the filtration layer at its edge.  A fabrication process for the filtration element that doe not damage the fragile microporous filtration layer involves helically wrapping the inner layer on a fixed mandrel to act as a carrier, and helically wrapping an over-lying layer of the microporous filtration material.  If an outer layer is used this is wrapped on the microporous material. All layers move in unison along the longitudinal axis of the mandrel. Each layer is self-overlapping and at least the fil-tration layer is sealed in the area of the overlap.

Abstract: ABSTRACT OF THE DISCLOSURE   In a reactive metal-water electrechemical cell, an alkaline electrolyte, containing soluble peroxide ions which improve the raiformity of reaction at the amode, reduces the amode's sensitivity to changes in the hydroxyl ion concentration of the electrolyte, reduces the amode's sensitivity to electrolyte flow rate and reduces the amode's sensitivity to temperature. The improved characteristics of the cell result from the ability of the peroxide ions to stabilize the amode and also to be reduced at a more electronegative potential than is required for the reduction of water.  The soluble peroxide ion, HO2, is formed when hydrogen peroxide, sodium peroxide and other soluble inorganic peroxide compounds are dissolved in the alkaline solution.

Abstract: ABSTRACT OF THE DISCLOSURE           A rechargeable battery provides a source of operating potential for an electronic circuit load.  An operator controlled on-off switch connects the battery to a relay, and through the normally open relay contacts, to the electronic circuit.  The relay winding is returned to ground through a capacitor.  When the switch is closed the relay is momentarily energized by the current which charges the capacitor.  A transistor has its collector-emitter path in parallel with the capacitor and its base coupled to the movable top on a voltage divider connected across the load.  In the absence of a low voltage condition across the load, the transistor conducts maintaining relay closure for normal circuit operation.

Abstract: Title of the Invention IMPROVED MATRIX PRINT HEAD AND SOLENOID DRIVER          Abstract of the Disclosure A matrix print wire solenoid actuator for a high speed wire matrix printer is disclosed wherein a small diameter print wire is propelled against printing paper and ribbon by the linear motion of the solenoid plunger, to which the print wire is attached, in an improved impact printer having one or more in number and variously arranged print wires for use in dot matrix printing.  High magnetic circuit efficiency, high repetition rate and minimized plunger coil heating and plunger mass are achieved by providing a continuous magnetic flux path through the solenoid interrupted only by two working air gaps of low reluctance for generating accelerating force on the plunger during coil energization.  The opposing air gap surfaces formed by the plunger and solenoid pole pieces are conical for insuring that both air gaps generate accelerating force on the plunger.

Abstract: RANGING SYSTEM WITH RESOLUTION OF CORRELATOR                AMBIGUITIES     ABSTRACT OF THE DISCLOSURE    A ranging system, particularly useful for sonic depth sounding employing a receiver utilizing one bit sampling of received  echoes.  A correlator correlates a sequence of one bit samples against a sequence of reference samples, such a sequence of reference samples being conveniently provided by a transmitter of sound waves.  An envelope detector circuit provides the envelope of received echoes and a peak detector provides the time of occurrence of the peak of the envelope.          A gate generator responsive to the time of occurrence of the envelope peak provides a gate signal which brackets a succession of output pulse signals from the correlator to delineate coarse range or depth while individual output pulses within the gated interval are applied to a second peak detector to give a range or a depth reading corresponding to the time of occurrence o-the maximum output pulse of the correlator.

Abstract: ABSTRACT OF THE DISCLOSURE      A system and method for providing an improved control store arrangement in which a single memory having a plurality of memory locations can be used for storing sequences of microinstructions or scratch pad information.  The number of storage locations defining the scratch pad area can be increased or decreased as required by assigning tag addresses to a desired number of scratch pad storage locations when the microinstruction routines are being assembled.  In this man-ner, the locations defining the scratch pad areas can be tailored to the particular system operation to be performed. This eliminates the need for modifying the control store circuits to change the size of the control store scratch pad area.

Abstract: ABSTRACT OF THE DISCLOSURE   The annular passage defined by the interior of a perforated liner and the exterior of a stinger pipe extending through the liner is substan-tially restricted so that the resistance to flow in the annular passage is increased sufficiently to maintain high fluid flow velocity outside the liner during gravel packing.  The increased flow velocity prevents the premature settling of gravel and stabilizes the formation of gravel dunes in the wellbore annulus, thereby significantly increasing gravel packing efficiency in inclined wells.  The proper flow restriction can be obtained using a wide diameter stinger pipe.

Abstract: A COMPATIBLE AM STEREO BROADCAST SYSTEM             ABSTRACT      A compatible AM stereo broadcast system has a pair of carriers in quadrature are separately modulated with stereo information.  The resulting signal is multiplied by the cosine of an angle ?, the angle between the vector sum of the two carriers and a line that bisects the angle between the carriers in quadrature.  The signal envelope contains the sum of the information on the two channels, thus providing compatible monophonic reception.  In a stereo receiver the two carriers in quadrature can be restored by dividing the signal by the cosine of the angle ?.  The original modulation can be obtained from each channel by product detection.
