Abstract: APPARATUS AND PROCEDURE FOR THE BELT           CASTING OF METAL               ABSTRACT OF THE DISCLOSURE           In apparatus for the continuous casting of metal in strip form between moving belts, belt support means comprising a multiplicity of elements that are distributed crosswise and lengthwise of a belt path area beside the mod space and are individually yieldable against a loading force, permit close belt stabilization to a selected path while yielding locally under excess outward force by the belt such as caused by solidified metal. Arrangement of belt support and cooling means along the mold space in successive sections each indi-vidually adjusted in respect to one or more of the conditions of: belt path taper; degree of compliance, if any, in the re-tention of the belt against the support; and cooling action; are such that these features, as well as provision, if desired, of local yieldability, permit accomodation of the apparatus to various requirements of casting operation.      A specific process for casting, well realized with the foregoing apparatus, includes controlling the stabiliza-tion of the belt along its path so that in a first zone where the metal is essentially liquid, the belt is held firmly against the supports, while in a second zone the belt may if necessary have soft support in the sense of locally following the surface shell of metal to avoid local impairment of cool-ing; this method may include provision of highly localized yieldability as by the above means, especially in later zones of the path where the metal completes solidification. Process -?-improvement is further afforded, with a closed path for liquid coolant, by recirculatin the liquid while controlling its temperature to a somewhat elevated level and if desired, ad-justing its chemical character.      The apparatus also has means for adjusting the con-tour of the belt support sections transversely of the path, e.g. to afford a profile concave toward the mold space for better assuring a flat product, such means coacting especi-ally with the individually yieldable support elements across and along the path. The belts travel around carriage struc-tures supported in desired relation to each other, with simpli-fied means for seperating one carriage from the other, for servicing purposes.     -?-

Abstract: METHOD OF PREPARING DIELECTRIC INSULATOR                   SEPARATED SUBSTRATE          FOR SEMICONDUCTOR INTEGRATED CIRCUITS            ABSTRACT OF THE DISCLOSURE         A dielectric insulator separated substrate is prepared which comprises a plurality of monocrystalline semiconductor island regions in which circuit elements are formed and a support region for supporting the island regions while separating them from each other electrically and insulatedly through a dielectric film.  After poly-crystalline semiconductor layers and at least one oxygen diffusion preventive film are laminated alternately to form the support region having its extreme outer layer comprised by the polycrystalline semiconductor layer, the extreme outer polycrystalline semiconductor layer is polished to such a thickness as to prevent the substrate from being curved greatly by the wedge action due to the oxygen diffusion.  The extreme outer poly-crystalline semiconductor layer thus polished exposes a flat surface, thereby assuring easiness of the prepara-tion of the substrate.  The substrate devoid of any curveness deformations permits a highly accurate forma-tion of the circuit elements in the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE A container for fluid products having telescoping parts and operable by outside manual pressure is provided. A base cup open at the top receives a plunger cup that is slidable therein with product being filled in both cups.  A slidable piston in the plunger cup dispenses product from the plunger cup concurrently with the dispensing of the same or different product by the plunger from the base cup.  A dispensing nozzle is provided in one of the cups with a transfer tube connecting the nozzle to the other cup.  The container assembly includes four injection molded plastic part, namely, (1) the base cup, (2) the plunger cup, (3) the piston and (4) the cap and nozzle assembly, these parts snapping together during the combined filling and assembling process.  Integral snap rings and snap beads are used to lock the parts together.  Once assembled, the piston locks the plunger cup against either in or out telescop-ing movement to prevent accidental dispensing during shipping and handling.  Additional break-off safety strip and heat shrink band at the juncture between the cups may be employed.  In pro-ducts requiring longer shelf life, the band may be required, as well as flip-up or rotary cutoff valves as disclosed.  Check valves may be advantageously employed, especially for products of low viscosity.  Different viscosity products are accommodated by sized passages and orifices, reducing inserts for the passages and/or multiple passages. The process provides filling the base cup, assembling the plunger cup and piston and combining with the base cup, filling the plunger cup and installing the cap and safety strip and seal band.

Abstract: APPLICATION OF: STANLEY K. JASINSKI, and FRANK A. ODORICO   FOR:             TREE TOP EJECTOR !     A B S T R A C T     An improved harvesting and processing apparatus for trees is provided.  The harvester is of the type having a gripping means disposed adjacent its forward end and a boom along its longitudinal axis.  A shear and delimber associated with the apparatus are longitudinally movable relative to the boom.  The shear and delimber are initially positioned adjacent each other.  During delimbing, the delimber moves rearward relative to the shear.  At the end of the delimbing stroke, the shear is activated to sever a bolt.  A greater pressure is then applied to the delimber blades so they grip the remaining trunk during the return stroke as the delimber moves forward.  At the end of the return stroke the delimber and shear have returned to their initial positions and a delimbed portion of the remaining trunk extends forward a sufficient distance to be clamped by the gripping means.  The pressure on the delimbing blades is reduced to the regular delimbing pressure, and the harvester is then in position to perform a second delimbing stroke, followed by a second return stroke, and if necessary, a third set of strokes.    When the desired portion of the harvested tree has been delimbed and cut into bolts an ejector located between the shear and the delimber is activated. The ejector ejects any remaining tree trunk and limbs which may be on the harvester away from the harvester.  Thus after rapidly delimbing and sectioning a tree, the harvester can be rapidly cleared for further harvesting.
