Abstract: MICROWAVE CIRCUIT BOARDS            Abstract of the Disclosure Microwave circuit boards and methods of making microwave circuit boards, the circuit boards having re-latively high dielectric constants, excellent moisture resistance, and reduced tendency to incur changes in di-mensions after processing.  The method comprises blend-ing in a polymer dispersion, a particulate filler mate-rial having a high dielectric constant and micro-fibrous material to form a slurry of polymer, filler, and fiber. A flocculant is added to the slurry to agglomerate the polymer particles, the filler particles, and the micro-fibers to produce a dough-like material.  The dough-like material is eventually formed into a sheet, and is there-after dried.  A conductive foil such as copper is then applied to both sides of the sheet to provide a microwave circuit board.

Abstract: DOUBLE DISK OPENER ASSEMBLY AND        DISK BLADE THEREFOR             Abstract of the Disclosure An improved double disk blade opener assembly and disk blade therefor are provided for a grain drill or the like.  A pair of bearings are supported on opposite sides of a seed boot casting or arm structure mounted on the implement.  Each bearing supports a threaded shaft which extends outwardly therefrom to a blade-receiving end.  A pair of generally flat disk blades each fabri-cated from a single piece of sheet metal and having opposed outwardly cupped central portions to accommodate the bearings are secured on and rotate with the shafts.  Mounting the bearings in the boot rather than in bearing caps on the blade decreases the overall width of the opener and increases trash flow between adjacent openers.  Socket screws which previously were used to secure the blade assembly to the boot, which required tapping of the boot and which frequently worked loose therefrom are elimi-nated.  The specially shaped disk blades retain the desired furrow cutting characteristics of conventional flat disk blades.

Abstract: ABSTRACT OF THE DISCLOSURE          For separating mold sand residues, particularly those containing zirconium and titanium oxide, from castings mechanical and electrochemical processes in salt melts have been used heretofore.  However, these processes are very costly; they corrode the surfaces of the castings or they fail in the case of difficultly soluble mold sand components.  These disadvantages are avoided when the castings with adhering mold sand residues are put into a melt consisting of 55 to 97% by weight of alkali hydroxide and 3 to 45% by weight of one or several fluorides of the first to third principal group of the periodic system of the elements and/or of zinc at 400 to 800°C.  The salt melts also contain 1 to 40% of a boron-oxygen compound and/or of boron-fluoride compound.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to skis, more particularly to a ski designed to be folded.  For locking the front and back parts of the ski into stretched out position, ready for use, it is possible to have a top part acting as a splint which is bolted, for example, to the inner ends of the two ski parts, preferably between two heel-pieces on top of the ski parts.  As a further possible design, the system for locking the ski parts into the stretched out or operable position, two links with a toggle function may be used, or the top face of the two ski parts may have a groove into which the top part is slipped.  As a further possible locking system, the two ends of the ski parts, nearest each other, are designed with a groove into which a locking core-piece with side teeth is placed and kept in position by a metal cover plate on top of it.  In a further design, as part of the present invention, a lever and a chain link are present on the top side of the ski at the position where its two halves are joined together.  One end of the chain link, furthest from the lever, is slipped over a hook and then the lever is pushed downwards pulling tight the chain link and making certain of a firm overall ski structure.

Abstract: ABSTRACT     Regulation of pressure at which fluid is allowed to flow is deter-mined by a device which is externally substantially monolithic in character and includes internal components assembled within it through an end coupling. Relatively low height and small girth are promoted by unique communication of internal flow around the edge of a diaphragm from one side and which is distinctively sealed only along the opposite side.  The device includes a hollow cylindrical body member, one end of which is internally threaded to serve as an inlet port connection and to receive and hold an externally-threaded insert which centrally carries a coaxial main valve, the movable stem of which is directed inwardly of the body member.  The insert traps a diaphragm inside the body which is backed by a spring and edge-clamped in sealed relation with a rigid cartridge member.  The exterior of the cartridge member is sealed with an interior surface of the body, but at least one passageway is afforded from the site of the main valve laterally across the diaphragm and around its outer edge and, thence, generally in an axial direction through the body member, to a downstream exit port.

A voltage application means applies to the decelerating grid such a voltage that only the outer electrons which defines the outer shell or envelope of an electron beam which has been subjected to the crossover in the vicinity of the pre-focusing lens and directed toward the main lens are subjected again to the crossover.  The blooming due to the spherical aberration of the main lens can be reduced to a minimum and the desired diameter of the beam spot can be positively maintained even when a high beam current flows.
