Abstract:
The invention relates to a method and an arrangement for optimising the operation of a fiberising device forming mineral fibres. In the method measuring values are collected from at least one fiberising rotor, forming mineral fibres, rotating around a horizontal or nearly horizontal axis and provided with a magnetic bearing, which measuring values describe the rotational track of the fiberising rotor around the magnetic bearing. Based on the obtained measuring values the shape of said fiberising rotor and change in the shape during the fiberising process are controlled. The invention also relates to a software product.
Abstract:
An improved system and method for addressing issues raised by denial of service attacks. The present invention provides for a "SIP washing machine," which acts as a SIP redirect server. The SIP washing machine asks a client contact to redirect its messages to a different IP address/other SIP server. "Fake" clients do not understand the redirection request, while valid clients understand the redirection request and act appropriately. Therefore, by acting as a redirect server, the SIP washing machine "cleans" the useless SIP traffic, while the operator's service continues to operate satisfactorily for legitimate users.
Abstract:
An improved system and method for implementing communications hand over in a simple manner. RTP is used to signal to other terminals that an IP address has been changed for a particular. The receiving communications application notices from the RTP data flow that the other party in a communications session has changed its IP address. Based on this information, the communications application adjusts the communications session without having to perform any session signaling.

Abstract:
Improved systems and methods for establishing peer-to-peer calls such as voice over IP calls and video over IP calls. In various embodiments of the invention, SMTP messages are exchanged between devices using a SMTP server, with the SMTP messages including IP address information. With this arrangement, the need for SIP service providers can be eliminated. In other embodiments of the present invention, SMS messages including IP address information are transmitted between devices during a GSM or other type of telephone call, enabling the call to "migrate" to a VoIP or video over IP call.

Abstract:
The invention relates to an arrangement and a method for the manufacture of mineral fibres. The system comprises a fiberising apparatus, which has at least two, typically three or more, fiberising rotors which rotate around a horizontal or nearly horizontal axis. Mineral melt is fed to the mantle surface of the first rotor, which mineral melt is thrown from the mantle surface of the first rotor to the mantle surface of the second rotor, and thence onwards to the mantle surface of a possible subsequent rotor, whereby mineral fibres are formed on the active mantle surfaces of the rotors. The blow-off means are arranged to surround the active mantle surfaces of the rotors of the fiberising apparatus and they are arranged in the immediate vicinity of the active mantle surfaces for blowing the fibres from the mantle surfaces towards a collecting member, which is arranged at a distance from the fiberising apparatus. Ready-made fibres are added with the addition means for ready-made fibres to the mass of the fresh fibres formed on the mantle surfaces, and binder is added with binder means to the mixture of fresh fibres formed on the mantle surfaces and ready-made fibres. The binder means are arranged in the immediate vicinity of the blow-off means and the addition means for the ready-made fibres are arranged on the side of the binder means, which is away from the blow-off means.

Abstract:
An arrangement for joining together wall or screen units (1, 2) comprising rails (3) arranged along the edges of said units which are to be joined together, and fittings (14) attachable to said rails and operable from the outside. The novelty of the invention resides in that the rails (3) comprise open grooves, defined side walls having longitudinal guide means (11) and inwardly collared flanges (8), one rail wall (8) having a series of slot-shaped holes (6), that the fitting (14) comprises a displaceable and fixable slide (15) provided with positioning means (17) and a through opening (18) for an axially non-displaceable, turnable sleeve (19) provided with a nut grip (24) and a socket-shaped portion (31) having cam curves (32) and a locking member (35) turnable in the sleeve (19) and axially displaceable against the action of a spring means (42), the locking member being provided with a locking head (36) at one end and, at the opposite end, with radially projecting means (46) adapted to be held in engagement with the cam curves (32) which comprise two portions, one steep (51) and one flat (49).
Abstract:
The invention relates to a method and an arrangement for transporting a mineral fibre web in the manufacturing process of a mineral fibre web. In the method, mineral fibres are manufactured using a fiberising apparatus, the mineral fibres are transferred from the fiberising apparatus to a collecting member, a mineral fibre web is formed on the collecting member, and the formed mineral fibre web is transported with a conveyor away from the collecting member for further processing. According to the invention, the formed mineral fibre web is transported a certain distance after the collecting member, supported by gas blows formed on the transport surface of the conveyor.
