Abstract: Embodiments disclosed herein are directed towards a compartmentalized housing configured to house components of an electronic device. The compartmentalized housing may include a pictorial parts map disposed on an inner surface of a cover of the compartmentalized housing, the pictorial parts map including an image associated with each type of component of the electronic device. Each image on the pictorial parts map is positioned at a location corresponding to where the type of component should be placed.

Abstract: A tool for treatment of rock, masonry or concrete by drilling, grinding or cutting off, the tool has a plurality of cutting segments each having a plurality of bonded cutting bodies formed as diamond crystals and subjected to an abrasive wear during an operation, a tool base body which carries the cutting segments, and at least one marking provided on at least one segment and forming a wear indicator, the at least one marking being arranged so that it changes during operation of the tool with wear of the cutting segments.

Abstract: An electric motor-operated grass cutter includes a housing; an electric motor; a plurality of cutting blades projecting from the housing, at least one of which is driven by the electric motor so as to reciprocate, and a chargeable storage battery connectable electrically with the electric motor. The storage battery also has a plurality of electrical contact lugs for charging. So that it can be charged safely and rapidly without disassembly the grass cutter also includes a charging socket mounted on the housing and accessible from the outside. The charging socket can have a plurality of additional contact lugs to facilitate electrical connection of a plug of an external charging device with the storage battery. The chargeable storage battery is structured so as to be quick-chargeable and external devices for quick-charging and trickle charging can be provided. A temperature contact lug can be provided for transmitting measured values of temperature for monitoring the quick charging.

Abstract: A scraper-chain conveyor comprises a plurality of channel sections joined together end-to-end. Each channel section has a pair of side walls joined together by a floorplate. The floorplates separate upper and lower runs for a scraper-chain assembly which circulates within the conveyor. Each of the side walls has a generally sigma-shaped cross-section defined by a V-shaped recess in that side wall. Each floorplate is connected to the side walls of its channel section at the bases of their V-shaped recesses. Each side wall of each channel section is connected to the adjacent side wall of each adjacent channel section by respective connection means constituted by a pair of coupling elements and a coupling member. One coupling element of each pair is attached to one side wall of a given channel section, and the other coupling element of that pair is attached to the adjacent side wall of the adjacent channel section.
