Abstract: ABSTRACT OF THE DISCLOSURE       A liquid pump is provided and particularly a downhole pump for use in an oil well bore for pumping oil or in a gas well to re-move condensate.  The downhole pump includes a plurality of pump and transfer modules, each of which includes an elongate housing with end couplings and with two internal passages extending there-through.  The pump module further has a bladder extending between the end couplings around the internal passages with the couplings having passages connecting one of the internal passages to space on one side of the bladder.  When fluid, preferably gas, under pressure is supplied to that passage, the bladder forces liquid therein upwardly into the next  module.  At the same time, fluid under pressure is exhausted through one of the passages from the space on the opposite side of the bladder of the next pump module, aiding it to receive liquid from the pump module therebelow.  The transfer modules supply the liquid up from a lower pump module to an upper one and connect the fluid passages to enable the fluid to operate the bladders.  The modules have  check valves at the lower ends enabling flow of liquid only in the upward direction.  However, the check valves have provisions for being opened when fluid under greater than operating pressure is applied thereto to enable liquid in the module to drain back down through the pump.

Abstract: ABSTRACT OF THE INVENTION         This invention is directed to a reamer-stabilizer which is useful in drilling oil wells and holes in mineral formations.  The reamer-stabilizer extends the life of the drill bit by maintaining the diameter of the hole to original specifications.  The reamer-stabilizer comprises a stabilizer portion which reduces excessive lateral movement of the drill bit, a reamer portion which reams away undersize portions of the walls of the hole and a rock chip grinding portion which breaks down oversize rock chips in the hole.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for assembling hollow balls from molded hemispheres which are fed to the apparatus. The hemispheres fed to the apparatus are received in a plurality of slots located about the circumference of a wheel.  While the hemispheres are in the slots, an appli-cator disc applies a solvent to the hemispheres and pressure cams force the hemispheres together, thereby forming complete balls.  The balls are then discharged from the apparatus.     The same apparatus may be used to assemble hollow balls from hemispheres which are adapted to be snapped together.  In that case, no solvent is applied by the applicator disc and the pressure applied by the pressure cams is used to snap the hemispheres together into hollow balls.

Abstract: APPARATUS FOR COUPLING SIGNALS TO OR FROM A TWO-WIRE LINE         Abstract of the Disclosure Voice-band signals are coupled to and from a telephone subscriber line via a low-pass filter which has a shunt capacitor coupled across the line.  In order to simultaneously couple above voice-band signals to and from the line, this capacitor is coupled to the line via windings of a transformer.  The above voice-band signals are coupled via the transformer to and from the line, for example via series inductors which are series resonant with the filter capacitor, as reflected through the transformer, at above voice-band signal frequencies.  A parallel resonant circuit, which has a low impedance in the voice-band, is connected in parallel with a winding of the transformer to prevent degradation of the filter characteristics in the voice-band.

Abstract: Attorney's docket 6994 CAN     INVENTOR:  BRUNO M?LHAUPT          INVENTION: CENTRIFUGAL SEPARATOR     ABSTRACT OF THE DISCLOSURE     A  centrifugal  separator,  especially  a  pusher centrifuge is disclosed, wherein at least one rotatable sieve or filter drum is mounted within a housing.  Within the sieve or filter drum there is arranged a to-and-fro displaceable pusher or thrust element, for instance in the form of a pusher floor member, which serves for displacing solid materials in the form of a filter cake towards outlet or discharge openings for the treated product.  To process thin suspensions with the pusher centrifuge the pusher floor member is arranged for oscillating movement between two turning or deflection points preferably located at the region of an imaginary central line of the sieve or filter drum.   A feed or  supply pipe for  the infeed of  the suspension which is to be separated extends substantially coaxially with respect to the sieve or filter drum and its outlet  or  outflow  opening,  which  extends  radially outwardly, is located essentially at the center between the turning or deflection points of the pusher floor member.     The pusher floor member further possesses a central opening which frees a passage for the supply pipe.  During the to-and-fro oscillating displacement  of  the pusher  floor member relative to the outflow opening of the feed pipe this outflow opening is alternately located to one or the other  side of  the pusher floor member.   The outlet or discharge openings for the treated product, i.e. the filter cakes are provided to both sides of the sieve or filter drum.  According to an alternative construction the sieve or filter drum can be moved relative to the pusher floor member.

Abstract: METHOD FOR FORMING RECESSED ISOLATED REGIONS                      Abstract A method is described for forming the recessed di-electric isolation in a silicon substrate involves first forming trenches which are less than about 1 micron in depth in areas of one principal surface of the silcion substrate where isolation is desired. Where, for example, an NPN bipolar transistor structure is planned to be formed it is usually necessary to have a P+ region underneath the recessed dielectric isol-ation to allow full isolation between the various bipolar transistor devices   A PNP transistor uses an N+ region underneath the isolation.  Where a field effect transistor is planned a channel stop can be substituted for the P+ region.  Under the circumstance of bipolar devices, the P+ region is formed in the substrate prior to the deposition of an epitaxial layer thereover.  The trench formation is caused to be formed through the epitaxial layer and into the P+ regions therein.  The surface of the trenches are then oxidized in an oxidizing ambient to form a silicon dioxide layer thereon.  A glass is deposited over this principal surface.  The glass used has a thermal coefficient of expansion that approximates that of silicon and has a softening temperature of less than about 1200°C.  The structure is then heated to a temperature that allows the flow of the deposited glass on the surface so as to fill the trenches.  The glass on the principal surface above the trench can be removed by a reactive ion etching method.  Alternatively and preferably, the glass is removed from areas other than the immediate area of the trench by lithography and etching tech-niques followed by a second heating of the structure to cause the glass flow to result in surface planarization.

Abstract: Abstract of the Disclosure Enzymes which are activated by pyridoxal phosphate are assayed in a dry analytical element which includes a high coverage of pyridoxal phos-phate.  The coverage of pyridoxal phosphate is such that the multiplication product of the coverage and the spreading coefficient of the element results in a reagent mixture concentration of at least about 0.9 mmole per liter when a liquid sample is contacted with the element thereby eliminating the need for a preincubation of the sample with a solution contain-ing pyridoxal phosphate.  The reactions for the determination of the enzymes are initiated by contact of the dry elements with a liquid sample.
