Abstract: The present application relates to a method and to an apparatus (12) for producing a corrugating roller, with a corrugating roller helical toothing having corrugating teeth (7). The method comprises the steps of providing a corrugating roller blank (1) which has a corrugating roller blank central longitudinal axis (3), and machining the corrugating roller blank (1) by means of a machining apparatus (12) having at least one machining device (16), with a relative displacement between the corrugating roller blank (1) and the at least one machining device (16), thereby producing the corrugating roller helical toothing. The present application further relates to a corrugating roller with an improved corrugating roller helical toothing.

Abstract: A package has a container formed with a dispensing opening and a supply of nonwoven disinfecting wipes in the container. The wipes are made of fibers containing lignin and impregnated with a disinfectant solution having at least two liquid components. A lignin content of the nonwoven wipes is between 0.02 g/m2 and 1 g/m2 and/or the disinfectant solution contains a dye. Thus if at least a part of one of the wipes is overexposed to air, it will change color as oxidized lignin and/or dye collects in it.

Abstract: A method for producing a nonwoven element particularly for hygiene products, has at least the following steps: forming a fibrous web sheet with a width direction extending transverse to the production direction and a thickness direction perpendicular thereto by supplying staple fibers from at least a first group which are formed from a thermoplastic material, consolidating the fibrous web sheet to form a nonwoven web by heating exclusively a first side of the fibrous web sheet through contact with a heated surface such that the staple fibers of the first group are partially melted, and cooling the nonwoven web.

Abstract: The invention relates to a method for examining the resistance of a connection between two bodies, whereby one of the bodies only has a small mass. A correspondingly directed force is exerted upon the connection until disconnection thereof. The force used is the centrifugal force which acts at a distance from a rotational axis in a concentric manner about said rotated connection. Said method is particularly advantageous if the body having a small mass is a coating which is applied to the other body. In order to obtain a sufficiently high centrifugal force, an examining stamp is applied to the body having the small mass and/or the coating on the side oriented away from the connection. The adhesion between the body and/or the coating and the examining stamp is greater than between both of the bodies and/or the coating and the other body.

Abstract: A network-accessible virtual environment includes objects that represent users of a service. The users are allowed to control their representative objects in the virtual environment to interact with other users represented in the virtual environment and also to become voice-enabled. Those users who are voice-enabled can speak with other voice-enabled users via phones.

Abstract: A communications system includes a teleconferencing system for hosting teleconferences, and a server system for providing a virtual representation for the teleconferencing system. The virtual representation includes objects whose states can be commanded to transition gradually. The server system provides clients to client devices, and each client causes its client device to display the virtual representation. Each client device is capable of generating a command for gradually transitioning an object to a new state in the virtual representation and sending the command to the server system. The server system commands the clients to transition an object to its new state by a specified time.

Abstract: A virtual representation includes objects that represent participants (i.e., users) in a teleconference. Volume of sound data in the teleconference is controlled according to how the users change location and relative orientation of their objects in the virtual representation.

Abstract: A virtual reality environment is applied to teleconferencing such that the environment is used to enter into a teleconference.

Abstract: Control of objects in a virtual representation includes receiving signals from audio-only devices, and controlling states of the objects in response to the signals.

Abstract: An apparatus for three-dimensional single-channel seismic measurements, wherein at least one seismic source and hydrophone devices are towed behind a vessel, and a pair of submerged deflectors are used and which, as the vessel moves, seek to move in a direction transverse to the vessel's direction of travel. Fastened between the deflectors is a wire which limits the spacing between the deflectors. Along the wire there are also mounted thereon hydrophone devices which in relation to the spacing of the devices have a short lengthwise extent. The devices are connected together by a hydrophone signal cable. An additional signal cable connects the cable to the signal processing equipment on the vessel. The seismic source may be connected to signal equipment on the vessel and located in an area between the vessel and the wire, or at least one of the deflectors may be equipped with a seismic source.

Abstract: An apparatus for three-dimensional single-channel seismic measurements, wherein at least one seismic source (1; 1?, 1?) and hydrophone devices (2) are towed behind a vessel (3), and wherein a pair of deflectors (4, 5) are used that are submerged in the sea (6) and which, as the vessel moves, seek to move in a direction transverse to the vessel's direction of travel. Fastened between the deflectors (4, 5) is a wire (7) which limits the spacing between the deflectors (4, 5). Along the wire (7) there are also mounted thereon hydrophone devices (2) which in relation to the spacing (d3) of the devices have a short lengthwise extent (d4). The devices (2) are connected together by a hydrophone signal cable (8). An additional signal cable (12) connects the cable (8) to the signal processing equipment (10) on the vessel (3).
