The present invention relates to a process of segregation for producing metals such as aluminum in a very high state of purity in respect of eutectic elements. The process comprises adding to a metal which is already very pure, at least one eutectic element, in a hypoeutectic amount, to ensure efficiency of the segregation operation. The added element or elements must be capable of being easily el...

The invention relates to an absorbent product, such as a sanitary napkin, comprising a fluid-impermeable layer (1) and a fluid-permeable layer (2) as well as a core (3) of absorbent material layer therebetween. Characteristic for such a product according to the invention is that at least the fluid-impermeable outer layer (1) extends somewhat beyond the two longitudinal side edges of the absorbent ...

An extended nip press for a paper machine for removing water from a wet paper, cardboard or that kind of a fibrous or porous web. The press comprises a rotatable press roll and two band rolls parallel to the press roll and an endless press band running around them which is pressed against the press roll for forming an extended press zone. The paper web to be dried is conveyed through the pressing ...

An extended nip press for a paper machine for removing water from a wet paper, cardboard or similar fibrous or porous web. The press comprises a rotating press roll and at least one stationary loading shoe as well as a band impermeable to a medium and movable between said press roll and loading shoe. The loading shoe is provided with a sliding surface against which the press roll is pressed throug...

A control system for controlling a double-acting cylinder includes four pilot-operated, proportional-type poppet valves for controlling fluid flow between the cylinder, a pump and a reservoir. Four solenoid-controlled pilot valves operate the poppet valves in response to error signals generated by a control circuit. The control circuit receives a cylinder position feedback signal and an operator-g...

A cable culvert (c) consisting of a number of steel fibre concrete elements, which is made up of two facing bowl-shaped elements and an intermediary ring-shaped element.

The sanitary tool is for picking up animal excrement in a bag, and comprises two closable grips between which the bag can be inserted. The grips comprise two identical, articulated scoops, hand grips and at least one spring arrangement tensioned between the scoops to bring them together. In this latter action, the scoops turn around a rotary link formed in a closed accommodation space.
