Abstract: In one embodiment, a proxy receives, from a client node, a file to be stored by a cloud storage server, where the proxy and the client node are part of a private network that does not include the cloud storage server. The proxy retrieves an encryption key associated with a user of the client node and encrypts the file using the encryption key. The proxy then transmits the encrypted file to the cloud storage server.

Abstract: A roll of material, e.g., thermoplastic ribbon comprises a hollow core made of a plastic strip of which the ends are mutually joined by overlapping, and the core's outer surface facing the material to be wound being of a nature opposing slippage of the material on it. The plastic strip includes an adhesive-coated foil of which the adhesive-fitted surface forms the outer core surface facing the material. The first winding layer facing the core bonds to this core and, as a result, the finished roll is made mechanically strong and this strength can be enhanced by an adhesive-coated plastic foil tautly enclosing the outside of the roll and fitted with a projecting, adhesive free or adhesive-neutralized tear-open tab.

Abstract: A roller device has a bearing axle and a wheel rotatably mounted to the axle in a roller housing. A lifting device is connected to the axle and wheel and is movable to raise and lower the wheel out of and into a travelling plane. A supporting device is fitted to the lifting device and has a support area lowered onto the travelling plane in response to rotation of the lifting device. The lifting device comprises a pair of eccentric discs which are mounted at both ends of the bearing axle and are connected thereto in a rotationally fixed manner. One of the discs engages in a form locking manner a corresponding recess in a side plate of the supporting device and at least one of the discs has two spaced apart spiked surfaces which can be rotated with the disc about the bearing axle in opposite directions against a stop protrusion on the side plate to thereby raise and lower the wheel.

Abstract: A universal local area network power line carrier repeater system and method provides: 1) LAN interfaces for converting high speed LAN data to high speed PLC data and high speed PLC data to high speed LAN data, 2) a high speed PLC data transceiver for exchanging PLC data with other repeaters, and 3) a repeater control system and method for arbitrating data communications on the power line medium among the plurality of repeaters seeking access to said medium.

Abstract: The invention concerns a process and a device for avoiding interruptions of operation caused by the strapping, on machines for the strapping of packing elements. The process is characterized by a second strapping coil with further strapping, and in that the leader of one of the two strappings is constantly kept at a standby position in the machine from which, upon removal of the other strapping from the strapping guideway, it is automatically fed to the strapping guideway. The device is characterized in that the feed system is preceded by a switch with two strapping guideways for a leader section for each one of the two strappings, with a strapping feed for the alternative introduction of one of the two strapping leaders into the feed system.
