Abstract: The authentication of a data receiving device prior to the transfer of data from a data storage device to the data receiving device over a wireless radiofrequency communications channel is described. One disclosed embodiment comprises conducting an authentication communication exchange in which one or more of an authentication request received from the data storage device and an authentication response sent to the data storage device is transmitted via an optical communications channel. This may allow the data storage device to ensure that a data receiving device requesting the transfer of data is a desired recipient of the data before transferring the data.

Abstract: A material processing plant comprises two screw-type extruding machines (1, 2) which are interconnected by means of a link (29). The link (29) is movable from a position of connection into an open position of release of the casing bores (12). Provision is further made for a mover (38) which acts on the link (29) for implementation of the motion.

Abstract: A screw loosening prevention structure and a gas-pressure device are provided. The structure includes a first member that is formed with a container space filled with gas, and includes a first threaded portion, a second member that includes a second threaded portion, wherein the second member is threadedly coupled with the first member by threadedly engaging the second threaded portion with the first threaded portion, and receives a pressure from the gas in the container space of the first member, and a spring member provided between the first and second members in a deformed state in which the displacement of the spring member is greater than a relative displacement of the first and second members due to a loosening factor including the gas pressure that is received by this second member.

Abstract: A method is described for controlling the exhaust temperature of an emission controlling device in the exhaust using both a higher heat loss path and a lower heat loss path along with parallel/sequential turbocharging. The exhaust path is adjusted based on a rate of change of temperature control error.
