Abstract: A gas turbine engine for an aircraft comprises, in axial flow sequence, a compressor module, a combustor module, and a turbine module, with a first electric machine being rotationally connected to the turbine module. The first electrical machine is configured to generate a maximum electrical power PEM1 (W), and the gas turbine engine is configured to generate a maximum dry thrust T (N); and a ratio S of: S = ( Maximum ? Electrical ? Power ? Generated = P E ? M ? 1 ) ( Maximum ? Dry ? Thrust = T ) is in a range of between 2.0 and 10.0.

Abstract: A box erecting machine includes a transport mechanism that can move an un-erected box from an entry portion of the box erecting machine to a forward portion of the box erecting machine. The transport mechanism can include pivot arm(s) and clamp(s) for securing and moving the un-erected box. The machine can also include a box erecting assembly that erects the un-erected box. The box erecting assembly can include an opening or unfolding mechanism that opens or unfolds the un-erected box into a generally rectangular tube. The machine can also include a folding mechanism and a closure mechanism for folding and securing the bottom flaps of the box.

Abstract: There is provided an inductive sensing circuit, comprising a signal generator, configured to generate a drive signal; one or more sensing arrangements, each of the one or more sensing arrangements comprising: two sets of one or more inductive sensing elements, configured in a half bridge arrangement, the two sets of one or more inductive sensing elements driven by the drive signal; a correction signal circuit, configured to generate a correction signal, wherein the correction signal is an adjustably scaled version of the drive signal; and a summing circuit, configured to sum an output signal of the two sets of one or more inductive sensing elements with the correction signal; and a demodulation circuit, configured to demodulate an output of the summing circuit of each of the one or more sensing arrangements.

The method further includes bending major and minor flaps on the unerected box relative to sides of the unerected box. The method further includes, while the major and minor flaps are bent relative to the sides of the unerected box, performing an automated opening operation on the unerected box, wherein the unerected box comprises a stacking fold.

Abstract: Apparatuses, systems, and methods are disclosed for a dual conveyor sorting system. An apparatus includes a first conveyor belt assembly that includes a first conveyor belt moving at a first rate in a first direction. An apparatus includes a second conveyor belt assembly that includes a second conveyor belt moving at a second rate in a second direction. The first rate is faster than the second rate and the first direction is the same as the second direction. The first conveyor belt assembly is positioned along a first axis perpendicular to the second conveyor belt assembly positioned along a second axis. A first edge of the first conveyor belt assembly is positioned substantially adjacent to a first edge of the second conveyor belt assembly.

Abstract: In a mobile satellite system, a system for providing satellite communication between multiple users in a closed user group arrangement includes first and second mobile earth terminals (METs) responsively connecter to and registering with the mobile satellite system. The first MET selects a closed user group network identifier (NET. ID) representing a NET group including the first and second METs to establish voice communication therewith and transmits the NET ID to a central controller. The central controller receives the NET ID from the first MET, validates the first MET for communication, validates the NET ID, allocates a frequency for the NET group, and broadcasts the message to the NET group including the second MET informing the NET group of the allocated frequency and the voice communication associated therewith. The second MET tunes to the frequency in response to the message broadcast by the central controller, and the central controller assigns the first MET as current speaker for the NET group.

Abstract: This invention is a portable hand operated viewer for micro-fiches and other material with writing too small to be read by the unaided eye. A translucent table has a clamp for the reading matter and that carries an adjustable binocular lens unit, with a head piece for correct location and for movement to scan the table. It is cheap and can be assembled by a child and is suitable for use in schools.
