Abstract: ABSTRACT OF THE DISCLOSURE The method of the present invention comprises coating the surface of particles, such as glass beads, with a first coat-ing, placing the coated particles in spaced relationship within a die so as to expose a portion of that coating, contacting that exposed portion with a second coating of material which forms an adhesive, and pressing the particles while still in the die against an electrode surface for a time and at a pressure sufficient to deform that surface and to bond the particles to that surface by the second coating without crushing the particles.  The particles may be imbedded up to about 35% of their average diameter.  The second coating is applied by a kiss coating technique utilizing a roller or the like.  The electrode is thus provided with strongly adherent, discrete spaced particles which act as a separator to space the electrode from another electrode or the like.  The method is simple, inexpensive, rapid and efficient.  The coating materials can be selected so as to be highly resistant to chemical and other forms of degradation in use.

Abstract: ABSTRACT OF THE DISCLOSURE            A construction for wooden stairs that pro-vides for rapid layout and assembly of the stairs by using an interlocking technique that locks the treads and risers into the stringers without the use of fasteners, adhesives or wedges.  The construction technique and the resulting unique stairs substantially reduces the layout and assembly time from that required by conventional stairs by accurately machining the re-quired dovetail grooves in the stringers and the cor-responding male dovetail on each tread and riser end.          Each tread and riser are then slid into place in the stringers and are interlocked so that once the stairs are assembled and interlocked, it is impossible for the components to become separated.

Abstract: ABSTRACT OF THE DISCLOSURE   According to this invention, a process is provided for preparing an ethylene copolymer having  a melt index of 0.1 to 10 and a density of 0.900 to 0.945.  The process comprises copolymerizing (1) ethylene, (2) at least one of propylene and butene-1 and (3) an  ?Y-olefin having 6 to 12 carbon atoms while maintaining the total amount of the components (2) and (3) in the range of from 1 to 40 mol% of the component (1) and the molar ratio of the component (2) to the component(3) in the range of from 0.01 : 0.99 to 0.90 : 0.10, in a substantially solvent-free vapor phase and in the presence of a catalyst comprising a solid substance and an organoaluminum compound, the solid substance containing magnesium and at least one of titanium and vanadium.  The reaction can be carried out in a very stable manner and in an extremely high polymerization activity, with decreased production of coarse or ultra-fine particles, improved particle properties and bulk density, and with little adhesion to the reactor and agglomeration of polymer particles.  The copolymer formed has a high melt index and superior physical properties, e.g., transparency, and can be easily and inexpensively obtained.  The copolymer has an extremely high transparency, good appearance and gloss, and excellent flexibility and elasticity even at a low temperature, not to mention at room tempera-ture.  It also exhibits a strength equal to or even higher than that of ordinary polyolefins.  The copolymer contains very few unsaturated bonds and very little residual catalyst or other impurities, so it is very superior in weathering and chemicals resistance and also in electrical characteristics, e.g., dielectric loss, break-down voltage and resistivity. It further exhibits a very high resistance to impact and to environmental stress cracking.  Consequently, the copolymer can be formed into various products, e.g., films, sheets, hollow containers and electric wires, by the existing molding methods such as extrusion molding, blow molding, injection molding, press forming and vacuum forming.  In the field of films, the copolymer exhibits its features because it is superior in strength, elongation, transparency, anti-blocking property, heat-sealing property and flexibility.  The copolymer which, when extracted with hexane, only gives an extremely small amount of extract and thus satisfied the "U.S.          Food Medicines Administration Standard on Extracts to be Contacted with Foods" (n-hexane extract not more than 5.5% by weight at 50°C.).  The copolymer can be used safely as a food packaging film.  It is also a suitable resin for blow molding because of its superior transparency, stiffness and resistance to environmental stress cracking.  It is further superior in electrical characteristics and is easy to be extrusion-molded, which allow the copolymer in question to be used suitably for electric wires.

Abstract: ABSTRACT:          Method of and arrangement for the determination of the pitch of speech signals in a system of speech analysis, wherein sequences of significant peak positions of the amplitude spectrum of a speech signal are derived from time segments of the speech signal by means of a discrete Fourier transform.  In order to reduce the influence of noise signals and noise components, respect-ively, in the amplitude spectrum the significant peak positions are compared with different masks, which have apertures at harmonic distances of an associated funda-mental tone.  The mask which matches the sequence of significant peak positions best is selected.  A probable value for the pitch is now computed with the harmonic numbers now known of the significant peak positions which are located in apertures of the selected mask.  The mean square error between these significant peak positions and the corresponding harmonics of the fundamental tone can be used as a criterion.  This method and arrangement can be used in so-called vocoders.

Abstract: ABSTRACT OF THE DISCLOSURE         A three phase gas pipe cable is disclosed which has at least one gas pipe cable section in which three phase conductors are arranged in a triangular configuration within an enclosing pipe.  Each phase conductor is supported by at least one supporting insulator such that the longitudinal axis of each phase conductor is substantially  parallel to the longitudinal axis of the enclosing pipe.  The supporting insulator  is connected by a slide bearing member to the enclosing pipe.  The slide bearing member accommodates an insulator foot end of the supporting insulator in such a manner that the supporting insulator is capable of motion in the direction of the longitudinal axis of the enclosing pipe.  When the phase conductors linearly  expand as a result of differential heating of the phase conductors, each phase conductor is free to expand in the longitudinal direction thereby moving the supporting insulator associated with each individual phase conductor a corresponding amount in the axial direction with no detrimental mechanical effects to any part of the gas pipe cable.  A single compensator for each phase conductor in each gas pipe cable section is sufficient to absorb the thermal expansion of each phase conductor.
