The two drip lines are connected one to the other by an annular hollow surface.

Abstract: A slight tube assembly, in combination with a sensing instrument, such as an optical pyrometer, for use in continuously monitoring the temperature of the first row of rotating blades in large gas turbines, particularly the type used in industry. Temperature data received by the pyrometer unit is fed to a control circuit, which regulates fuel input to the tubine to control the firing temperature. The key to obtaining reliable blade temperature data in the practice of this invention is the position of the sight tube in the turbine, which enables the pyrometer to "view" the rotating blades along a direct line of sight that penetrates a hot gas duct, but not the turbine section of the engine.

Abstract: A method for the production of polyolefin resins containing both an organic amide and a zinc compound. One composition is prepared which contains the polyolefin and the amide, but which does not contain the zinc compound. Another composition is prepared which contains the polyolefin and the zinc compound, but which does not contain the amide. The two compositions are extruded separately, and the individual resins so obtained are blended to form the desired resin composition containing both the amide and the zinc compound, thereby preventing the zinc stearate from catalyzing the dehydration of the aliphatic amide to a nitrile.

Abstract: Process and apparatus for extruding synthetic resinous thermoplastic materials, wherein a heat plastified stream of such material is divided into a primary or core stream, and non-primary or secondary stream(s), the secondary stream(s) heated to a temperature substantially hotter than the core stream, and the hot secondary stream(s) thereafter layered onto the opposite surfaces of the core stream prior to expelling the material from an extrusion die. Such a process and apparatus is practiced to avoid a loss of surface smoothness in the extruded product.

Abstract: A cell for absorbing and electrolyzing the water vapor transmitted from a sample used in an apparatus for rapidly determining the water vapor transmission rate through plastic films or like structures and water content in solid, liquid and gaseous materials wherein electrolysis of the water vapor from a test sample takes place in a cell electrolysis assembly comprising a first electrode support and a first electrode and a second electrode support and a second electrode with a formaminous matrix having an electrically conductive water absorption material therein disposed electrically between the first and second electrodes. The water vapor transmission rate or water content of the sample can be rapidly and accurately determined by quantitative mass spectrometer calculations of the oxygen and hydrogen generated during electrolysis or by calculation of the electrical current needed to electrolyze the water vapor which are related with primary accuracy.

Abstract: Method of quantitatively determining chloromethyl methyl ether and/or bis-chloromethyl ether at greater sensitivity comprising utilizing an alkali metal salt of a lower alcohol and a readily detectable organic hydroxy compound in lower alcohol medium in a salt-to-hydroxy compound molar ratio of from about 0.2:1 to about 5:1 to react, when warmed, with either or both of said ethers, to form derivatives thereof; adding water to the reaction mixture and an immiscible hydrocarbon solvent; agitating and partitioning the mixture and directing at least a portion of the immiscible organic solvent extract onto a suitable gas chromatograph, preferably packed with glass beads with a stationary liquid phase thereon and more preferably with the beads coated with OV275 as the liquid phase; and eluting the reaction product or products off the column and through a detector therefor with an inert gas.

Abstract: A cable shielding tape comprising a first layer of substantially pure aluminum bonded to a second layer of aluminum alloy which can beneficially be used in cable constructions designed for the transmission of electric power or communications. The cable shielding tape may be formed as a strip having one or both sides coated with or laminated to an adhesive thermoplastic resinous polymer. The tape is disposed within a cable at the desired location to provide good mechanical and electrical properties therein. In addition to providing good mechanical and electrical properties for a cable, the aluminum/aluminum alloy shielding tape substantially reduces the problem of bi-metallic galvanic corrosion caused as a result of interfacing metals having widely differing electrolytic potentials.

Abstract: A compression stressed liner for refrigeration equipment and a method of stressing the same is disclosed. The effective life span of refrigeration equipment liners can be significantly increased by compression stressing. Stressing liners in compression before or during assembly of refrigeration equipment is accomplished by bending the liners, molding the liners to form a shallow arc in one direction of its structure or shrinking the liners and then securely attaching the same. Compression stressed liners counteract localized tensile stresses that normally develop because of shrinking of the liners during use at temperatures substantially below assembly temperatures. Compression stressing of liners also reduces the size of or eliminates foramina on the exposed surfaces of the liners, normally increased in size by the tensile stresses, thus decreasing chemical penetration and attack of liners.

Abstract: A heat or thermal energy storage structure comprising a crosslinked polymeric resinous matrix having a plurality of substantially unconnected small closed cavities and a heat sink material encapsulated within the cavities. The structure is characterized in that the heat sink material forms an essentially stable dispersion in the uncured polymeric resinous matrix when mixed therewith before the matrix is crosslinked. The structure can beneficially be used in conjunction with low level heat or thermal energy collector means and heat transfer means to provide a space heating or cooling apparatus. The storage structure may also be effectively used to provide an additional function of a building component in a building construction such as a wall structure.
