Abstract: FLOATING GRAIN BIN EXTENSION FOR   USE WITH AGRICULTURAL COMBINE                     ABSTRACT OF THE DISCLOSURE           A grain bin adapted to be mounted on the upper part of an agricultural combine is provided with at least one "floating" bin side wall extension which is automatically movable into substantially vertical grain-retaining position as the bin approaches and reaches a full condition.  Clean grain which has been separated from the straw, chaff or the like is conveyed by an elevating conveyor which discharges the grain via a chute into the intake end of an elongated "floating" bin loading conveyor which is pivotally mounted for angular move-ment in a vertical plane.  In the illustrated embodiment, the bin loading conveyor is an auger conveyor and the rotatable shaft of the floating auger conveyor is driven by a suitable drive means through a universal joint.  As the grain level in the grain bin approaches a full condition, the bin loading conveyor moves angularly upwardly from a horizontal position due to an upward thrust on the bin loading conveyor caused by the reaction of the grain discharging from the bin loading conveyor against the upper surface of the already loaded grain.           In the illustrated embodiment, a pair of oppositely disposed bin side wall extensions are hingedly connected to the fore and aft walls of the upper edges of the grain bin, the bin wall extensions normally being folded downwardly in a lowered position.  The respective bin wall extensions are connected by suitable link means to the floating bin loading conveyor whereby upward pivotal movement of the loading conveyor, as the level of the grain in the bin approaches a full condition, causes the bin wall extensions to be swung upwardly about their hinge connections into a vertical grain-retaining position.            When the grain bin is unloaded, the hinged bin wall extensions move downwardly with the pivoted bin loading conveyor to a substantially horizontal lowered position.

Abstract: ABSTRACT OF THE DISCLOSURE   In a subsurface formation, where shaliness affects the results of typical electrical will logging measurements, partial water and partial hydrocarbon saturations are determined from measurements of dielectric constant.  A relation defining dielectric constant change as a function of partial water saturation is used to determine the partial water saturation and partial hydrocarbon saturation.  The relation between dielectric constant and conductivity due to shaliness in a partially water saturated formation is also used to determine partial water saturation and partial hydrocarbon saturation of said formation.  The value of "shaliness exponent" for the formation is determined from measurements of dielectric constant as well.

Abstract: LOW MOLECULAR WEIGHT MESOPHASE PITCH     ABSTRACT OF THE DISCLOSURE:     A low molecular weight, anisotropic pitch consisting of essentially 100 percent mesophase and suitable for spinning into continuous filaments can be prepared by passing an inert gas through an iso-tropic carbonaceous pitch at a rate of at least 4.0 scfh. per pound of pitch while heating the pitch at a temperature of from about 380°C. to about 430°C. to produce mesophase and simultaneously agitating the pitch so as to produce a homogeneous emulsion of the mesophase produced and the remaining non-mesophase portion of the pitch, said heating and agitation being continued until the pitch has been essentially completely converted to mesophase and the emulsion has been transformed into an essentially single phase system.  When examined under polarized light, the pitches of the present invention are seen to consist of a single phase which is essentially com-pletely anisotropic. The fibers spun from such pitch are also essentially completely anisotropic and can be further processed to produce carbon and graphite fibers having a high Young's modulus of elasticity and high tensile strength.

Abstract: ABSTRACT OF THE DISCLOSURE          Mica flakes are separated from other particulate material and classified according to their aspect ratios (i.e. ratio of average diameter to thickness), by a combination of screening and dropping a mass of mica flakes optionally mixed with other particles into an air stream flowing in a direction making a substantial angle with the vertical, and having a high degree of uniformity and low turbulence, so that the particles and flakes assume trajectories determined by their terminal velocities.  The distance downstream travelled by a flake or particle is           proportional to its terminal velocity, which in turn is inversely proportional to the product of diameter and thickness of the flake, and to the density of the particle or flake.  Receptacles are provided at different downstream distances from the location of introduction of the material, below the flowing air stream, into which particles and flakes of different terminal velo-cities are collected.  Previously or subsequently, the flakes are screened to separate them on the basis of diameter, to give a final separation according to aspect ratio.

A conductor plate is provided in-side the ski and has at least one threaded opening therein for threadedly receiving a screw which facili-tates a fastening of a base plate for a ski binding member to the upper surface of the ski.  The screw is threadedly received in the opening and the base plate of the ski binding member is clamped between the head of the screw and the upper surface of the ski.  The screw is electrically insulated from the base plate of the ski binding member but does provide a metal-to-metal contact with the conductor plate.  The base plate of the ski binding member and the conductor plate are electrically conductive so that these two plates can function as com-ponents of an electrical circuit embodied within the ski. A battery can be mounted within the ski and the afore-mentioned base plate and conductor plate utilized in circuit with the battery to provide power to electrical loads located elsewhere on the ski, as for example in the ski binding members.

Abstract: ABSTRACT      A dental implant system to provide a mechanically self-sufficient artificial tooth possessing a functional pseudo peridontal ligament that does not cause resorption of the supporting bone and ultimate loss is disclosed.  The im-plant includes a core component that withstands the masti-catory loadand transmits such load to the root system. The root system comprises an outer component that adheres to the jawbone and possesses a similar modulus of elasticity thus capable of transmitting masticatory stresses along its interface with the bone without excessive stress concentrations and an intermediate component adhering tightly to both the core component and the outer component and having a much lower modulus of elasticity than either the core com-ponent and the outer component.  The longitudinal movement of the core component causes the oblique or diagonal stretch-ing of the intermediate component which pulls or applies a force on the outer component which tends to contract it and creates tensile stresses in   the portions of the supporting jawbone which interface with the outer component. Such tensile stresses cause bone deposition and stabilize the implant further.
