Abstract: The present invention relates to a method for data transmission from a first user equipment to a base station of a cellular network, where the first user equipment is camping on under coverage enhancement conditions, the first user equipment being communicatively connected to at least one second user equipment via a device-to-device communication channel, wherein for the data transmission of at least one data packet, the method comprises the steps for the first user equipment of: transmitting the at least one data packet to the at least one second user equipment via the device-to-device communication channel, instructing the at least one second user equipment to transmit the at least one data packet time-synchronized with the first transmission to the base station.

Abstract: A method for operating a user equipment in a cellular network, the cellular network comprising a plurality of base stations, wherein at least one base station is configured to maintain neighbor relation data, wherein the user equipment is operating with an active base station in narrowband communication category, the method including, for the user equipment—receiving from the active base station a measurement instruction message, the measurement instruction message containing at least one restriction parameter relating to at least one of a reporting time indication and a minimum power level indicator, —receiving a connection release message, —measuring signals from at least one neighbor base station considering the at least one restriction parameter, and, on occasion of a reconnection—transmitting at least one neighbor measurement report to the active base station.

Abstract: A discharge lamp includes a lamp tube containing a noble gas, two internal electrodes, and a secondary electrode disposed outside and close to the surface of the lamp tube. In one embodiment, studs are disposed on the lamp tube so as to affix the secondary electrode. In an alternate embodiment, a reflector includes an indentation pointing toward the lamp tube and configured as the secondary ignition wire.

Abstract: A process for the dewatering and particle classification of solids from suspensions, e.g. coal from a slurry in which the coal is transported, makes use of a dewatering centrifuge having two frustoconical centrifuge drum sections of different inclinations such that in a first filtering zone the particles are preliminarily dewatered and then pass by automigration to the next centrifuge drum at which further dewatering takes place. The suspension on the first sieve surface forms a thin layer classification zone having a thickness up to 5 mm and in which the coarse fraction is retained while the fine fraction is passed. The coarse fraction automigrates to the next sieve surface where it is dewatered and the fine fraction separated out in the thin layer classifying zone is then filtered under pressure in a subsequent stage.

Abstract: A rotary filter has a pressure vessel and a rotor from which a plurality of filter cells are suspended from outer portions of the rotor so that they clear a conveyor located proximal to the axis of rotation and upon which the filter cake is removed. Conduits are connected to the filter cells from a single distribution head for initially evacuating the cells in the filter stage and thereafter pressurizing the cells to dislodge the filter cake while the vessel remains under pressure. The filter cells can have the filter surfaces extending generally in axial planes or in axially spaced relationship in planes wherein a plurality of angularly spaced filters extend generally radially from respective filtrate conduits running axially along the outer part of the rotor.
