Abstract: Foreliggende oppfinnelse vedrører en fremgangsmåte og dertil tilhørende anordninger for å kunne utføre vedlikehold, reparasjoner, etc. av nacellen (4) og propellgruppens rotorblad (17) til vindmøller installert til sjøs, under adkomstmessige og arbeidsvennlige nye forhold, i den forbindelse, ifølge oppfinnelsen, blir nacellen (4) og propellgruppen (17) senket ned til samme nivå som adkomstbåtene (19) har. Den provisoriske monterte beskyttelses konstruksjon (8) muliggjør en slik nedsenking uten at det vertikale propellbladet (17) kommer i forbindelse med sjøen. I sin nedsenkede posisjon vil konstruksjonen (8) også gi vindfrie og tørre arbeidsforhold for vedlikehold og reparasjon av propellbladene (17) eller slepes eller går for egen maskin til land for utskifting av rotorbladet (17). For større reparasjoner, vedlikehold eller utskifting av hele nacellen (4) kan propellbladet (17) som er tredd ned i konstruksjonen (8), løsnes fra nacellen (4) og hele nacellen (4) med resterende propellerblad (17) sliskes over på en transport lekter (11) for inntransport til havn. Etter utførte arbeidsoperasjoner og eller utskiftinger, reverseres nedsenkingsoperasjonen og nacellen (4) med propellgruppen (17) løftes opp til sin energiproduserende nivå. Fremgangsmåten og dertil tilhørende anordninger, ifølge oppfinnelsen, kan også benyttes i forbindelse med varslet ekstrem vær ved å senke nacellen (4), sammen med tårnet og propellgruppen (17), ned til en lavere og sikrere nivå.

Title: Lighting fitting
Inventor: HOLTEN PETRUS ADRIANUS JOSEPHU
IPC: F21V11/02
Filed: 1996-02-08
Abstract: A luminaire has a housing with a light emission window (2), a tubular lamp supported in the housing facing the window (2) and having a center line extending in a plane P perpendicular to the window (2), side reflectors (5), and three-dimensional lamellae (10) which each have an outer edge (11) and a pair of inner edges (12). The outer edge of each lamellae is concave in a direction transverse to the window. The luminaire thus provides an optimized cut-off angle, screening light which would otherwise be dazzling but permitting non-dazzling light to pass. Each of the lamellae has a concave curvature in a direction parallel to the plane P but which flattens out going from plane P towards the side-reflectors (5). That enlarges the aperture through which light emanates and makes the illumination provided by the luminaire more uniform.

Title: Method of and apparatus for safety identyfying a mobile user roaming within a communication network
Inventor: TSUDIK GENE
IPC: G06F21/34
Filed: 1994-10-27
Abstract: A method and an apparatus are provided for securely identifying a mobile user while avoiding trackability of his/her movements, i.e. it provides a way for a secure user identification in secrecy. The gist is to encrypt the user's identifier, and/or his/her password, and a synchronization indication, preferably a fixed time interval, under a secret one-way function and sending the encrypted message, called a "dynamic user identifier", to the user's "home authority" where he/she is registered. The home authority comprises correspondence tables listing, pre-computed for every time interval (or another chosen synchronization), the dynamic user identifiers and the corresponding true identity of the user and can thus quickly decide whether the received encrypted message originates from a registered user. On the other hand, an intruder is neither able to detect from the encrypted messages the identity of the user nor can he/she track a user's moves.

Abstract: PCT No. PCT/EP97/06249 Sec. 371 Date Dec. 1, 1998 Sec. 102(e) Date Dec. 1, 1998 PCT Filed Nov. 11, 1997 PCT Pub. No. WO98/24676 PCT Pub. Date Jun. 11, 1998A multiple-unit railway vehicle having three car bodies where the respective neighboring car bodies are each connected in a pivoting manner to one another by means of a single coupling, and each car body sits only on one two-axle truck. In the vicinity of the respective center pivot and possibly also on the trucks, there are actuator elements that are used to influence the articulation angle between the longitudinal axes of the car bodies. To control the articulation angle so that when the train is traveling over a curved segment of track, the car bodies assume a position in relation to one another that corresponds at least to a significant extent to the static rest position of the railway vehicle on the corresponding section of track, the profile and curvature of the track are determined during travel for the segment of the track that currently lies between the first and last trucks, and from that measurement, the set point position is determined, and by means of the actuator system measurements are taken to counteract at least an overshooting or undershooting of the set point value.

Material to be separated into a light phase is supplied through inlet ports (6) in the body, and the heavy phase is discharged through discharge ports in the bowl at one end of the conveyor. Between the inlet ports and the discharge ports for the heavy phase, the body of the screw conveyor carries a baffle (8c), generally shaped as a radial rib which forms a helical surface turning in the same direction as the screw (7). Owing to its shape the baffle actively contributes to the transport of the heavy phase, and with retention of the same gap between the baffle and the inner surface of the bowl, the gap area can be increased by increasing the axial length of the baffle.

Title: Method of obtaining water-soluble, powdered derivatives of cellulose
Inventor: SCHLESIGER HARTWIG
IPC: C08J3/12
Filed: 2001-02-26
Abstract: The present invention relates to a new, particularly economical process for preparing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a superheated gas mixture, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The superheated gas mixture, with which the feed composition is contacted, is selected from: (i) a superheated gaseous mixture of steam and an inert gas; and (ii) a superheated gas mixture of steam and air. The superheated gas mixture has a steam content of 40 wt. % to 99 wt. %, based on the total weight of the superheated gas mixture.

Filed: 1999-10-01
Abstract: A valve assembly includes a valve body and, located therein, a valve member which can be moved between a first position, in which the valve is in a first operational mode, and a second position, in which the valve is in a second operational mode. The valve member has a rare earth magnet which, when the valve member is in either one of the two operational modes, causes the valve member to be magnetically biased against movement toward the other operational mode. The valve is provided with a device for generating a magnetic field sufficient for overcoming the magnetic bias in the first or second operational mode, so as to cause the valve member to move to the other of the operational modes.

Title: Self-heating or self-cooling containers
Inventor: SEARLE MATTHEW JOHN
IPC: B65D81/34
Filed: 2000-02-28
Abstract: A self-heating container (10) has an internal cavity (22) for its contents and an external cavity (20) for a heating mechanism, for example, comprised of first and second chemically reactive materials which are arranged to be mixed when heating is required. A closure (30) closes the external cavity (20). When the heating mechanism is operated to mix the chemicals and cause an exothermic reaction, vapor, such as steam and hot air, is produced. The vapor is constrained to flow to the exterior of the closure (30) through grooves (62) therein. A sleeve (60) is arranged around the container (10) contiguous to the closure (30) such that the exiting vapor is constrained to flow between the sleeve (30) and the can (10). By this means, a user of the can is protected from coming into contact with the hot steam and air and the heat in the vapor generated can enhance the heating process. Preferably, the sleeve (60) is constructed of an absorbent material, such as a cardboard, to absorb any condensates and this absorbent material is surrounded by an impermeable plastics material to insulate the user from the heat of the reaction.
