Abstract: Provided is a stator assembly of an axial flux electrical machine that includes stator coils and core segments arranged circumferentially to define a segmented stator core. Each core segment has a tooth part extending axially and adapted to mount a respective stator coil. The stator core can also be non-segmented with tooth parts arranged circumferentially. Adjacent mounted stator coils are spaced apart by a substantially trapezoidal void. The stator assembly also includes stator coil retainers. Each retainer is received in a respective void between a pair of adjacent mounted stator coils and its position in the radial direction is independently adjustable and each also includes at least one channel for receiving a cooling fluid and a pair of contact surfaces that are spaced apart in the circumferential direction and each retainer applies a contact pressure to the respective pair of adjacent mounted stator coils through the contact surfaces.

Abstract: Provided is a gearless conveyor drive for driving a conveyor belt of a conveyor system that includes a substantially tubular barrel having a radially outer surface adapted to contact the conveyor belt, and a stationary shaft that is supported by a pair of support structures, each support structure supporting a respective axial end of the shaft. A first drive unit includes a first rotor assembly and a first stator assembly that includes at least one first rotor fixedly connected to the barrel for rotating the barrel relative to the shaft and the first stator assembly includes at least one first stator fixedly connected to the shaft.

Abstract: A data communication system for construction machines for uploading data from and downloading data to other construction machines that may have better and/or more frequent communication connectivity to an off-board computer that is connected to a computer network.

Abstract: A casing for a portable communication device having an operating face comprising a fragile input region providing recesses for operation of respective user input elements and a protection arrangement protruding beyond the fragile input region having an external profile that provides a plurality of contact points defining a contact plane such that when placed face downwards on a generally planar surface, the fragile region is spaced therefrom and impulses received on contact between the generally planar surface and the operating face are substantially dissipated away from the fragile region.

Abstract: A portable communication device is disclosed comprising a front face (3) having a plurality of openings therein, and an array (6) of keys. Each key has a switch actuator, a switching element, and coupling means. The switch actuator has an upper surface bounded by side walls, and the switch actuator of each key of the array (6) protrudes from one of the plurality of openings to provide its upper surface for tactile actuation by a user and is physically discrete from the others. The coupling means couples the tactile actuation of the upper surface by a user to the switching element.
