A radial tire carcass fabricated by a first stage process has bead portions which are placed over a pair of spaced-apart coaxial bead seats. The bead seats may be segmented radially expandable rings which are expanded by fluid pressure into engagement with the bead portions. The tire carcass is initially positioned on the drum with the bead seats at a spaced-apart distance so that upon expansion o...

An interference image of a biaxially stretched film strip 4 is generated optically. Streaks in the film strip are areas of different orientation and/or thickness d which are distinguished from the streakfree areas in the interference image by clearly different intensities. In order to generate the interference image, a light-source 1, a diffuser screen 2 and a polarizer 3 are arranged on one side ...

An extrusion molding tool for the production of a drill blank made of a plastic raw material by extruding the material in a longitudinal extrusion direction across a production mandrel and through a bore in a die, the bore having a longtiudinal axis, the mandrel having at least one elastically deformable wire radially spaced from the longitudinal axis projecting into an intake end of the bore for ...

A splice between ends of precured tread material is effected by establishing a gap between the ends that are to be spliced together after the tread material has been fitted to the buffed area of a tire with a cushion layer of uncured rubber between the material and the buffed area. The gap is established without compressing the tread material adjacent the gap and is approximately three-sixteenths ...

Upper and lower rollers have grooves for a bead ring having a clamp area portion produced by a bead winding machine. The bead ring is placed in the groove of the lower roller with the beginning of the clamp area portion in position for pressing by lowering of the upper roller so that the bead ring is engaged by the groove in the upper roller. The rollers are oscillated between the pressing positio...

Electrochemical biosensor systems or apparatus, components thereof, and methods for quantitatively measuring or assaying concentrations of selective substrates or metabolites in aqueous media as a function of electrochemical response to hydrogen peroxide concentration, using immobilized enzyme electrode means selective for the substrate or metabolite being measured.

Disclosed herein are free-standing, pinhole-free, ultrathin, polyarylate films having thicknesses of about 400 angstroms or less and a process to prepare them. The films find particular utility in separatory applications.

A polyester film containing 20% or less by weight of a mixture comprising a white pigment and a pearlescent pigment is disclosed. The polyester film has a pearly luster and a high degree of whiteness.

A hair dryer includes a hand grip with a push switch for energizing the electrical components of the dryer. The components are turned on by depression of the push switch when the grip is held by the user and are automatically turned off when the user releases the grip. A holder with an insertion socket carried by an angularly adjustable neck is provided for supporting the dryer by insertion of the...

PURPOSE:To improve surface properties of a fine cell-containing film, particularly smoothness and bonding properties by laminating a polyester film of density larger than the specific value on one or both surfaces of a polyester film containing a number of fine, closed cells and having density in the specific range. CONSTITUTION:A film layer (layer B) almost not containing any fine, closed cells i...

The presentation means 5 comprise a presentation head 50 carried by a flexible belt 55 mounte...

Werkwijze voor het bereiden van soepel polyurethaanschuim, waarbij men een polyether polyol met een gemiddeld moleculair gewicht van 1000 tot 8000 en een gemiddelde functionaliteit niet groter dan 4 in reactie brengt met een organisch polyisocyanaat in aanwezigheid van een schuimstabilisator, een katalysator en een blaasmiddel dat methylformiaat bevat waarbij men aan genoemd reactiemengsel een ver...

A method of removing heavy metals from aqueous solution, a composition of matter used in effecting said removal, and apparatus used in effecting said removal. One or more of the polypeptides, poly ( gamma -glutamylcysteinyl)glycines, is immobilized on an inert material in particulate form. Upon contact with an aqueous solution containing heavy metals, the polypeptides sequester the metals, removin...

Printed wiring boards useful for high frequency applications are obtained by laminating a copper foil pretreated with a silane to a polynorbornene prepreg. The prepreg is made by impregnating a fiberglass cloth with a ring-opening polymerized polymer. The copper foil is pretreated with a silane which is capable of improving the bond strength between the copper foil and a norbornene copolymer.

Disclosed herein are free-standing, pinhole-free, ultrathin, polyphenylene oxide films having thicknesses of about 400 angstroms or less and a process for preparing them. The films find particular utility in separatory applications.

A thermal transfer dyesheet having a printing surface against which a receptor substrate may be held to receive a thermally transferable dye in response to thermal stimuli applied to the dyesheet, the dyesheet comprising a substrate supporting a dyecoat comprising the thermally transferable dye dissolved in or dispersed throughout a polymeric binder, characterised in that the polymeric binder comp...

A film prepared from a compatibilized resin blend comprising an olefin polymer, a polymer of a vinyl aromatic monomer and a compatibilizing amount of a graft copolymer of a vinyl aromatic monomer and an EPDM rubber exhibits improved properties making it highly desirable in such end uses as grocery and trash bags.

Disclosed is a curable epoxy resin composition having excellent flexibility and toughness, comprising (a) an epoxy resin, (b) a glycol type di(meth)acrylate, (c) a nitrogen containing heterocyclic compound, and (d) a polyamine having at least two amino groups with an active hydrogen. The resin composition is very suitable for a vibration damping laminate.

An aqueous composition containing an organic oxygenate, such as a ketone or alcohol can be separated by pervaporation across a non-porous membrane separating layer of a blend of polyvinyl alcohol and a polyacrylic acid.

An electromagnetic device such as an electromagnetic brake or an electromagnetic coupling comprises an electromagnet, at least two parts arranged so that, when the electromagnet is switched on, a magnetic flux extends through the parts.
