Title: Plug valve
IPC: F16K5/02
Filed: 1977-04-05
Abstract: A valve, of the type employing a plug rotatable through substantially 90 DEG between open and closed valve positions, employs a plug which has an elongated configuration along its axis of rotation with the opposing ends of said elongated plug each exhibiting a spherical, ellipsoidal, or other curved configuration that merges smoothly into the elongated sides of the plug. The plug is provided with a passageway which is elongated in the direction of elongation of the plug and which extends through the plug in a direction transverse to the axis of rotation of the plug. The plug surface is sealed relative to the valve housing by at least one continuous seat of elongated closed loop configuration which engages the surface of the plug along a continuous noncircular line or band having a direction of elongation extending generally in the same direction as the central axis of the plug. The valving and sealing functions of the improved valve are similar to those of a conventional spherical ball valve, but achieve a given port area by use of a plug having a smaller cross section relative to the turning axis, than would be required of a ball exhibiting that port area.

Title: Method of manufacturing optical fibre preforms
IPC: G02B6/00
Filed: 1978-03-21
Abstract: In the manufacture of silica optical fibers a tube having an internal coating of a volatile dopant is locally heated by a hot zone repeatedly traversed along its length to promote shrinkage and finally collapse of the tube bore. During the shrinkage prior to the final collapse traversal a gas flow of oxygen and a halide of the volatile dopant is maintained through the tube in order firstly to provide a small overpressure to ensure circularity in the shrinkage and secondly to compensate for the tendency for dopant to be lost by volatilization.

Title: Method of machining solids of revolution by rotary cutting tools and a toolholder for carrying same into effect
IPC: B23P17/00
Filed: 1978-04-03
Abstract: A method of machining solids of revolution by a rotary cutting tool whose effective portion is shaped as a solid of revolution set on a spindle and having a circular cutting lip, said solid of revolution being imparted rotation during the cutting process, wherein the tool axis is positioned in the plane parallel to the basic plane passing through the axis of machine centers and makes up an angle with the projection of the axis of machine centers on said plane. The distance from the plane of the tool axis to said basic plane and said angle of setting the tool axis are estimated using the following relation: H=(D/2) sin omega +(d tg omega /2 2ROOT sin2 phi +tg2 omega ) where H is the distance from the plane of the tool axis to the basic plane passing through the axis of machine centers D is the diameter of the workpiece being machined d is the diameter of the circular cutting lip omega is the central angle of setting the tool point with respect to the basic plane phi is the angle of setting the tool axis with respect to the projection of the axis of centers on the plane of the tool axis. The toolholder for carrying said method into effect comprises a body having an inclined top bearing surface and provided with longitudinal ways, a tool clamp mounted traversably along the body ways and fixably in a required position on the inclined body surface, and having a hole for the tool to accommodate. The hole in the tool clamp makes up an angle with the body ways and is parallel to the body base, whereas the angle of elevation of the inclined top bearing surface of the body is equal to a preset central angle of setting the tool point with respect to the basic plane passing through the axis of machine centers. The present invention is instrumental in increasing vibration resistance of the cutting process and adding to the quality of workpieces machined.

Title: Polyvinyl alcohol pellets containing a plasticizer, and method for their preparation.
IPC: C08J3/20
Filed: 1979-03-16
Abstract: For the thermoplastic processing of polyvinyl alcohol, the processing temperature must be below the decomposition temperature of the polyvinyl alcohol this is attained by incorporating plasticizers.
