Title: Push-pull services for the internet
Inventor: SABNANI KRISHAN KUMAR
IPC: H04L29/08
Filed: 1999-05-04
Abstract: In an arrangement that employs a push-pull paradigm, information that is to be communicated to clients is broadcast, or multicast, to cache servers, wherein the information is cached in preparation for its being pulled by clients. By pushing information to points close to the clients, both source overload and network overload are avoided. The pushed information in the disclosed approach is transmitted over Internet links, or over other communication channels, such as cable and radio systems.  In operation, clients subscribe to specific services of the provider, an association is established between the subscribing client and a cache server, and the server informs the network that it should be included among the destinations to which information from the provider is transmitted. When information is subsequently transmitted by the provider and received by the cache servers, it is stored in the cache server in preparation for its being pulled by the clients, as desired and when desired.

IPC: B25B21/02
Filed: 1999-07-21
Abstract: A hammering screwdriver 1 for tightening and loosening screws offers the possibility of operating the rotating action alone when tightening the screws, and a rotation/hammering action when loosening the screws. This is primarily attained by the construction of the cam controller casing 2 between which and the hammering mechanism cage 6 a ball 10 is arranged. With this exclusively rotating motion, this ball 10 lies in a salient 16 below an elevation 8 on the head end 7 of the cam controller casing 2. With rotation/hammering motion, the ball 10 is moved over the track 3 to the head end 7 of the cam controller casing 7 until it reaches the elevation. Here the cam controller casing 2 moves forward in an axial direction owing to which hammering action occurs.

Title: Introduction of fiber-free foam into or near a headbox during foam process web making
Inventor: ROKMAN KAY
IPC: D21F1/02
Filed: 1998-09-03
Abstract: In a foam laid process for producing a non-woven web of fibrous material (such as of synthetic or cellulose fibers) substantially fiber free foam is introduced at various locations in or adjacent to a headbox to get improved results. By introducing pure foam into the foam/fiber mixture near (e.g. just before) where the foam/fibre mixture is introduced into the headbox a more uniform basis weight profile of the non-woven web produced may be provided (e.g. a basis weight variation of about 0,5 % or less). By introducing another stream of substantially fiber-free foam into the headbox at a surface remote from the foraminous element, to flow along the surface (typically parallel to the flow of the foam/fiber mixture), it is possible to minimize shear of fibers in the headbox so that the fibers do not become unidirectional, in the direction of movement of the foraminous element, and keep the surface clean. The surface is typically a roof surface of an inclined headbox.
