Abstract: ABSTRACT OF THE DISCLOSURE             A cable branch-off sealing member and a method of making a cable branch-off seal using the sealing member.  In the method, a heat shrinkable material is wrapped around two closely spaced parallel cables and pinched together between the cables to one side of the cables to create a loop of heat shrink material between the cables.  The cable sealing member has an elongate tongue smoothly tapered at its leading end for insertion into the loop of heat shrinkable sheet material, which tongue has a width greater than the spacing between the cables to bridge between the peripheries of the cables and is bowed centrally of its width along its length to cause the two layers of heat shrink material to bow outward midway between the cables.  A narrow tail is connected to the trailing end of the tongue generally midway of the width of the tongue and extends perpendicular to the length of the tongue to extend into the space between the peripheries of the cables to maintain the spacing between the cables and to keep the tongue generally centered between the cables as the heat shrink material is heated and shrunk.  The narrow tail has smooth surfaces for contacting the cables to assure that it will not damage the cable sheaths during the heat shrinking process.

Abstract: ABSTRACT OF THE DISCLOSURE       A submarine cable with optical fibers which prevents damage to the fibers due to tensile stresses or water pressure without the use of an external armor.  The cable has a central core with an anti-torsional wire rope around which a plurality of tubes are helically wound.  Each tube loosely contains at least one optical fiber, and the spaces within the tubes and any spaces within the rope are filled with a substantially incompressible fluid.  The core is surrounded by a sheath of plastic material which contacts the tubes and the rope in a manner which eliminates voids between the sheath and the core elements.  The rope may have a cladding of plastic material, and the rope may have a wire or tape of good conductivity metal for supplying electrical power to repeaters.

Abstract: FERROELECTRIC LIQUID CRYSTAL DEVICES            Abstract In a display device utilizing ferroelectric (e.g., chiral, smectic C material), a stabilizing electric field perpendicular to the cell surfaces forces the molecules to orient themselves in one of two states both of which are parallel to the cell surfaces.  A particular state is selected by a switching electric field also oriented perpendicular to the cell surfaces.  The stabilizing field has a half-cycle time shorter than the switching time of the ferroelectric material, whereas the switching field duration is longer than or equal to the switching time of the material.  The invention enables the use of relatively thick (e.g., ? 2 µm) ferroelectric cells.  (FIG. 5).

A method of manufacturing a semiconductor device including the step of depositing from the vapour phase layers on a substrate in the chamber of a reactor in which a vector gas and a reactant gas are introduced, characterized in that the vector gas and the reactant gas are introduced into the chamber of the reactor by means of a system of three coaxial tubes, the first of which (the inner tube) has a diameter smaller than that of the second tube (the intermediate tube), which in turn has a diameter smaller than that of the third tube (the outer tube), the first ends of these tube being independent, but the second ends thereof situated in the proximity of each other cooperating with each other so as to form a valve controlling the introduction of the reactant gas into the hot zone of the chamber of the reactor mixed with a vector gas, these tubes being disposed in such a manner that: the said second end of the inner tube merges into the intermediate tube, the said second end of the intermediate tube provided with a restriction merges into the outer tube, the said second and of the outer tube provided with a restriction merges into the chamber of the reactor in the proximity of the hot zone, the said first end of the intermediate tube is provided with a valve V, in that the reactant gas is introduced through the first end of the inner tube and circulates in the direction of the second end to the intermediate tube, in that the vector fluid is introduced through the first end of the outer tube and circulates in the direction of the second end to the chamber of the reactor, in that, the flow rate of the vector gas being chosen to be very much higher than the flow rate of the reactant gas, the tube system behaves like a commutation valve which directs the whole quantity of reactant gas to the chamber of the reactor when the valve V is closed and to the first end of the intermediate tube when the valve V is opened.

Abstract: Process for copolymerisation of acrylonitrile with at least one conjugated aromatic olefin comprises adding at least a part of the olefin to the reaction mixture during reaction, to form a copolymer with a mol. ratio of acrylonitrile: olefin of 2-6:1, the reduced viscosity (measured on a 0.5% soln. indimethylformamide at 25 deg.C) being 0.5-1.2 (for a mol. ratio below 4:1), and 0.5-1.8C for a mol. ratio of above 4:1). The process is employed for the prodn. of copolymers of crylonitrile with conjugated aromatic olefins, particularly styrene, in which the olefin units are evenly distributed throughout the polymer chains. This is achieved by controlling the mol. ratio of acrylonitrile: olefin, together with the mol. wt. of the copolymer, as indicated by its reduced viscosity. The copolymers have excellent mechanical properties, and are very suitable for injection moulding.

Abstract: A self-supporting sandwich element for use as a roof or wall element in smaller or medium-sized houses. The element is made up of two parallel metal plates at a certain mutual distance apart and the interspace between them is filled with foamed concrete made of cement, water and a bicomponent foaming agent. By keeping the bulk density of the foamed concrete down within the range 200- 600 kg/m3, an element having a low heat transmission coefficient (0.06-0.10 W/(m3 . K)) is obtained. Because of the good adhesion between the metal plates and foamed concrete and the good strength characteristics of the foamed concrete, an element is obtained which has very good bearing strength and is insensitive to shock.

Abstract: A filter system for collecting amalgam-containing sludge and heavy metals from dental clinics. The filter consists of 4 circular pipes having smaller and smaller diameters such that these pipes can be placed inside each other, thereby resulting, when they are closed at the top and the bottom, in a chamber system which has an inlet in the outer diameter of the filter and an outlet in the middle of the filter. These chambers have to be connected internally by overflows from chamber to chamber. These overflows are placed in a staggered manner above each other such that the water in the filter has to flow upwards in order, finally, to reach the outlet connection. The circular form of the chambers will bring about a centrifugation of particles which are heavier than water, such that these particles are kept away from the internal passages of the chambers. In addition, a number of water-borne, air-filled PVC spheres are placed in chamber 1, which spheres decrease the turbulence of the water as it flows through the filter. In addition, these spheres remove surface tensions from saliva and blood, such that even very small particles sediment.
