Abstract: Docket No. PC-989 METHOD OF CLARIFYING AND REMOVING WATER      FROM WATER-SOLIDS SUSPENSIONS    Abstract of the Disclosure A method of clarifying and removing water from water-solids suspensions wherein the solids are formed into flocculent masses and clarified water is continuously removed by the withdrawal thereof through a screen.    The present invention relates generally to the clarification and removal of water from water-solids suspensions, and more particularly, but not by way of limitation, to the removal of clarified water from sumps or pits containing spent aqueous drilling fluids and the like.    In industry waste aqueous solids suspensions are often produced and accumulated in sumps or pits.  For example, in the drilling of oil and gas wells, aqueous drilling fluids are commonly utilized.  Such drilling fluids contain both cuttings produced in the drilling of the wellbore which are brought to the surface by the drilling fluid and various fluid loss additives, weighting materials and other additives for controlling the fluid loss characteristics, density and other properties of the drilling fluid during use.  Commonly, the drilling fluid is circulated down the wellbore being drilled and back to the surface from where it is routed to a sump or pit which functions as an accumulator as well as a settling basin for the heavier cuttings and other solids which settle by gravitation out of the drilling fluid.  At the end of the drilling procedure, the aqueous drilling fluid containing suspended solid materials must be disposed of.  With the em-phasis on environmental protection, the disposal of spent drilling fluids and other similar industrial wastes presents a problem.    Heretofore, in the disposal of water-solids suspensions contained in sumps or pits, solids flocculating additives have been utilized to form the suspended solids into flocculent masses whereby the masses gravitate to the bottom of the pit allowing clarified water to be removed from the top of the pit.  Such methods involve numerous treatment steps and are time consuming and expensive.  For example, in treating spent aqueous drilling fluids contained in mud pits, the heretofore used methods involve dispersing a solids flocculating additive into the drilling fluid to form suspended  solids into floccu-lent masses, allowing the flocculent masses to settle a short distance and when withdrawing clarified water from the top of the pit.  Additional solids flocculating additive is dis-persed in the remaining fluid in the pit and after the flocculent masses formed have again settled a short distance, additional clarified water is withdrawn from the top of the pit.  This procedure is repeated until a major portion of the water con-tained in the pit has been clarified and removed, often being incomplete and requiring a long period of time to accomplish, typically a matter of days.

Abstract: METHOD FOR MAKING CONDUCTION-COOLED CIRCUIT PACKAGE             Abstract A method for making a circuit package which exhibits an excellent heat transfer path from a semiconductor chip or other heat generating device to the heat sink can or cover of the package.  A heat conducting pad is placed in proximate relationship to either the heat sink or to a surface of the chip and is metallurgically bonded to the other.  In one of the preferred embodiments a low melting point solder, such as indium or an alloy thereof, is metal-lurgically bonded to the inside of the heat sink cover in a limited central region thereof.  The solder is then posi-tioned adjacent the chip and reflowed to substantially fill in the gap between the solder and the chip, but with no stress between the chip and the solder.  The assembly exhibits excellent heat transfer from the chip to the cover and any associated heat dissipating structures.  The pre-ferred method involves the reflow of a mass of solder against the back side of the chip, which has previously been solder-bonded on the front side to conductors on the surface of an alumina substrate.

Abstract: ABSTRACT OF THE DISCLOSURE     A disc press for continuous pressing of aqueous or suspended pulp for fractionating the pulp in a liquid fraction and a dry substance fraction, comprises two plane parallel pressing discs mounted for rotation about a shaft and having strainer plates which haul the pulp therebetween by friction.  The press also comprises inner and outer pressing means extending between the pressing discs and together with the latter define a curved pulp passage which in the transport direction has a varying cross section and constitutes a filling or dewatering zone, a pressing zone and a discharge zone.  The passage zones of the pulp passage combined extend throughout an angle which is less than 360°, and the filling or dewatering zone has an approximately constant cross section.  The subsequent pressing zone (B) has a uniformly decreasing cross section the centerline of the pressing zone following an arc having an approximately constant radius about the axis of rotation.  The pressing zone of the pulp passage has an outer confining surface which is shaped as pivoted arm having a curved concave surface, the arm at its one end being mounted for swinging about a point at the start of the pressing zone and at its other end being connected to a power means in the form of an adjustable hydraulic cylinder which holds the arm with a predetermined force, and which when the pulp pressure in the press exceeds a predetermined value, will influence and displace the pivoted arm.  Possibly, the pressing discs are kept at a correct mutual distance by an hydraulic cylinder which acts as an additional safeguard by automatically opening the complete pulp passage when the pressure in the press exceeds a given threshold value.

Each contact of the connector utilizes three spheres of equal diameter defining a tricuspid interstitial space there-between into which the end of a fiber is mounted.  The spheres are embraced by a circular race.  In the preferred embodiment, the spheres engage each other and the race.  When a pair of contacts are mated in axial abutting relationship, the spheres in the mating contacts nest with respect to each other, thereby precisely later-ally aligning the optical fibers which are mounted in the intersti-tial spaces of the sets of spheres in the two contacts.  In another embodiment, the spheres are dimensioned so they do not engage each other, but engage the optical fiber at three points.  Also, more than three spheres may be mounted in a contact for positioning a fiber therein.

Abstract: ABSTRACT OF THE DISCLOSURE             A method and apparatus are provided for handling heat-softenable batch material.  The batch components are mixed together and then mixed with liquid and formed into pellets of substantially uniform size and shape.   The pellets are preheated in a heat-exchange chamber through which hot gases are passed from a melting unit to which the preheated pellets are supplied, saving considerably on energy requirements.   A physical characteristic such as the depth of a portion of the batch being formed into the pellets is sensed, the depth being related to moisture content.  The ratio of the batch material and liquid is regulated in dependence upon this sensing to achieve uniformity in pellet size.  Size uniformity is important in maintaining relatively free flow of the hot gases through the pellets in the heat-exchange chamber.
