Abstract: A carrying device (10) comprises one or more storage pouches (12), at least one shoulder strap (14), intended for carrying, connected to the storage pouch. An attachment member (20) is intended for attachment of a long narrow object (3) and comprises a first part (21) and a second part (22), being releasable from one another. The first and second parts have a respective connecting end and a respective fixation end. The connecting ends are configured to receive and lock one another. The fixation end of the second part is configured to allow attachment to a long narrow object (3). The fixation end of the first part is fastened on the storage pouch, the shoulder strap or a frame, at a position proximally behind one of the shoulders (4), thereby allowing freedom of when said long narrow object is secured. A method for handling a carrying device is also disclosed.

Abstract: A dust separator in which a plurality of elongated emission electrodes are detachably held at one end in respective holder fittings secured to a pair of parallel, slightly-resilient inner frame members, or holders, which in turn are secured to substantially non-resilient outer frame members, and at their other ends in at least one holder fitting secured to a common cylindrical central holder extending between and parallel to the frame members; the electrode assembly is tensioned by adjustment of screws fastening said inner frame members or holders to said outer frame members. In one form the holder fittings are hollow cylinders through which the electrodes extend, and the electrodes are positioned in the fittings by their bent-over ends and clamped therein by tubular members forced into the hollow cylinders. In another form, specially-shaped holder shoes are used, in which dove-tailed ends of the electrodes are held.
