PURPOSE:To reduce the load of the roofing against the side plate of the tank and to lower the moment of overturn at the time of earthquake by means of anchoring of the terminal part of dome roofing on the upper part of the concrete body.

PURPOSE:To manufacture a foamable heat-shrinkable tube capable of easily shrinking and foaming on heating, by winding a foamable thermoplastic resin sheet having heat shrinkability with an adhesive layer in two or more layers.

Fibres are produced by centrifugal spinning a solution of a thermosetting aldehyde resin, e.g. an aqueous UF resin solution, and drying the fibres by contact with a stream of hot, dry, air flowing downwardly from above the spinning cup. To avoid premature drying of the resin solution and fibres, a stream of cold, humid, air is fed to the spinning cup (5), from whence it is thrown, by rotation of t...

A multiple optical core fiber and method for manufacturing it. Two or more chemical vapor deposition type preforms are fused with a hydrogen-oxygen torch and then etched in a solution of 50% hydrofluoric and 50% nitric acid. A hollow quartz tube is subjected to internal gas pressure while a hydrogen-oxygen torch is passed along it. This expands and cleans the tube. The chemical vapor deposition pr...

PHN 829 1 3.3.76 An apparatus is described for reading a record carrier, on which information, for example video and/or audio information, is stored in an optically readable track-shaped information structure. Errors in the focussing of a read beam relative to the plane of the information structure can be detected with the aid of two detectors which are disposed in the far field of the informatio...

Disclosed is a diaper comprising an absorbent body, diaper end margins defining front and back waistline regions and lateral margins extending between the end margins. Each lateral margin has a predetermined unconstrained length between those end margins. The diaper further comprises limiting means operative to shorten the length of a lateral margin from its unconstrained length.

A disposable product and a process for manufacturing the disposable product on a flexible conveyor. The disposable product has an absorbent core formed by sandwiching a corrugated tissue between two separate feeds of fluffed pulp. Upper and lower layers of wadding are provided, the lower wadding being first folded around the absorbent core longitudinally and then an upper wadding is laid on top. T...

Baling apparatus is disclosed which is capable of baling waste material which is not shredded prior to being fed into the baler. The apparatus includes an enlarged baling chamber with two reciprocal baling heads moving in perpendicular direction, each having a shearing blade fixed thereto which engage each other and a blade fixed to the side wall of the chamber to shear off material extending abov...

This invention relates to adducts of tetra-substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particular fillers, including pigments; the compositions of fillers and the aforesaid adducts with epoxy resins and other casting resins; the reaction product of said adducts with aromatic polyamines; the use of said reaction products for curing epoxide and ...

A method for etching at least one aperture having a defined crystallographic geometry in single crystals which includes masking the crystal to protect predetermined portions thereof from being etched, and then anisotropically etching with a mixture of sulfuric acid and phosphoric acid.

A method and apparatus for controlling the temperature of a spraying zone in a process of fabricating heat-reflecting glass sheets by a traversing spraying means which is located over a transfer line of a hot glass sheet. The spraying zone is enclosed in an inner hood, which is in turn housed in an outer enclosure to provide a substantially closed heat-controlling space on the outer side of the in...

Production of a polyurethane embedding material from an aromatic diisocyanate in stoichiometric excess with a polyol mixture consisting essentially of castor oil and trimethylolpropane to first form a prepolymer containing unreacted isocyanate groups and being sufficiently flowable to permit coating onto membrane surfaces in all types of coating methods, and subsequently hardening the prepolymer b...

1454379 Coating glass PPG INDUSTRIES Inc 10 Dec 1973 [15 Dec 1972] 13829/76 Divided out of 1454377 Heading C1M An apparatus for applying a coating to a glass ribbon by directing on to the substrate a mixture of gaseous reactants comprises means for supporting the substrate and a nozzle elongated in a direction transverse to the ribbon for delivering the gaseous mixture. The nozzle 43 converges fro...

The leading end of an intermittently fed flattened tubular web is clamped by a gripper, whereupon a severing mechanism cuts a section from the web. The gripper advances the leading end of the tube section before the trailing end has cleared a pair of clamping rollers and while a folding roller engages an intermediate portion of the section and moves it laterally to form a loop in the tube section ...

The apparatus has an exit slit (13) and a passage for communication of product including a main conduit (1), a plurality of secondary conduits (2) which are of equal length and internal diameter and a primary slit (6) communicating with a chamber (7)....

PURPOSE:To absorb the amplitude fluctuation dependent upon the irregularity of head efficiency and the unevenness of a medium by using an amplitude discriminator independent of data patterns to reduce the time constant of a LPF and make a high-speed response possible and rducing the drop of control signals even in case of no input signal. CONSTITUTION:Variable gain amplifier GAC where input signal...

The ideal response expected of an electromagnetic transducer, particularly of the Magneto-Resistive (M-R) type, obtains with signal translating circuitry for amplifying the varying signal produced and for dynamically biasing the transducer for maintaining the transducing operation in the linear portions of the characteristics of both the transducer and the amplifying circuitry. An M-R transducer i...
