A non-woven fibre product in which the fibre material consists, totally or in part, of fibres which are able to form bonds with natural or artificial fibres of the same or different type, and in which said fibres capable of forming bonds are cellulose carbamate fibres.

A method of, and apparatus for, separating phases in a polyphase system is described and particularly in separating oil from produced water by the contact of gas bubbles and oil droplets by a dispersed gas flotation technique. A polyphase system is divided into at least two portions. The pressure of one portion is reduced to form bubbles of a gas, the the two portions are then recombined whereby t...

The invention provides a process for production of silver-containing precursor alloys to oxide superconductors, said alloys having reduced amounts of intermetallics. Powders containing metallic elemental components of an oxide superconductor are high energy milled for a predetermined amount of time to increase homogeneity of the mixed metallic elemental components of the oxide superconductor. Silv...

A rigid foam, especially a largely closed-cell polyurethane or polyisocyanurate rigid foam, includes a cell structure being formed by the expansion of rigid foam raw materials with carbon dioxide as an inflating agent. The cell structure is substantially homogeneous and has a cell content of substantially CO2 inflating agent and proportions of a physical inflating agent being at least substantiall...

A method of moving and guiding a cart on a course, comprising the step of burying magnetic elements under a ground surface of the course to form a marker line in a moving direction of the cart. The magnetic elements comprise different poles defining one of S-shaped and zigzag-shaped routes and a predetermined route of a cart movement. A pole polarity is sensed for switching movement of the cart be...

PURPOSE:To reduce the deformation of a tread rubber of a tire during the release of a die by inclining a tread groove forming bone and a carf molding blade to the center line in the cricumferential direction of a tread forming surface within a specified range of angle. CONSTITUTION:In the meridional section of an upper die, angles at which side wall surfaces 8a and 8b of a tread groove forming bon...

A method of manufacture of a pneumatic tire in which an annular component, such as a tread/breaker assembly, is accurately located in a supporting box (30)(l5). Other tire components such as sidewalls, and carcass, are assembled to said annular component whilst it is held in the box. The box (l5) (30) is a transfer box which is detachable from a rotatable conveyor (ll) for relocation in turn at ea...

The known center mechanism in a tire vulcanizing machine is improved in that the center mechanism comprises condensate ejection means which can be accommodated within a member disposed in the center mechanism and which can be moved between the member and a condensate stagnating portion, a sleeve movable vertically within an upper ring by an operation of a pneumatic cylinder and adapted to be engag...

PURPOSE: To prevent a necessary rotational work from being reduced by the compression of a release spring at the time of a frontward twisted overturn by specifiedly constituting a control plate and angle levers respectively. CONSTITUTION: A toe piece is provided with a casing 2 which is fixed to a ski board 3 and has an axial hole 2b. A release spring 5 is stored in the hole 2b, its one end is sup...

Disclosed is a skin packaging film for skin packaging high profile and/or heavy articles. The film comprises linear ethylene/alpha-olefin copolymer. In one embodiment, the film is antistatic and may be employed for skin packaging of electro-static sensitive items such as circuit boards.

A change-speed construction for a propelling system of a work vehicle. The construction has a neutral return mechanism for causing a stepless transmission to return to the neutral in response to disengagement of a main propelling transmission clutch. Then, when the clutch is engaged again to resume vehicle run after a temporary stop for e.g. replenishment of materials to be worked, the vehicle doe...

This invention provides a process for preparing a heat shrinkable film by extruding a blend of elastomer, hydrocarbon oil and polyolefin to form a film, stretch orienting the film to form a stretched film, annealing the stretched film while still under stress, then cooling while further maintaining stress on the film. This invention further provides a process for preparing an elasticized composite...

A method and apparatus are disclosed for producing polyolefins by a fluidized gas phase polymerization process utilizing two stacked, substantially vertically aligned, reactors (10, 40) and a substantially vertical product transfer line (70) for transfer of intermediate polyolefin polymer product from the polymerization zone (14) of the upper reactor to the polymerization zone (44) of the lower re...

A dimensionally heat-recoverable article carrying a heat curable adhesive coating on a surface thereof, the adhesive coating comprising (a) a mixture of substantially solid particles of a first reactive component with separate substantially solid particles of at least a second reactive component and (b) a water soluble polymeric binder having substantially no hydroxyl groups, the first and second ...

A polyorganosilsesquinoxane fine powder having a moderate hydrophilicity, which is surface-treated with a block- or graft-copolymer comprising a polyoxyalkylene segment and a polysiloxane segment.

A thermosetting resin containing composition can be heated to reduce its viscosity and used as a liquid in a liquid injection molding method. It has a phenolic resin content of about 80% to about 90% solids by weight, and contains about 5% to about 40% of a polyglycol. The composition may also contain resorcinol as a compatibilizing agent and a polyalkylene glycol as the polyglycol agent. In a nov...

The present invention relates to styrene polymer foam containing carbon black and includes both particulate and extruded forms. Such foams have decreased thermal conductivity.

A method is provided for detecting outflow of fluid from an offshore wellbore to a surrounding earth formation or inflow of fluid from the formation of the wellbore. The wellbore is in fluid communication with a conduit extending between the wellbore and an offshore structure floating above the wellbore, which wellbore and conduit are at least partly filled with a body of fluid. Liquid is injected...
