Abstract: The present invention relates to an optical aiming device of the type having a light source and a mirror or lens reflecting or projecting an image of a reticle, i.e. a sight, to the eye of a user. The optical aiming device comprises means for attaching the optical aiming device to a weapon, such as a shot gun. The optical aiming device comprises a base part comprising the opticals and at least one attachment member for attaching the base part to the weapon. The base part and at least one attachment member are displaceable with respect to each other. The relative displacement can effectively be used to dampen the recoil force imparted to the base part carrying the sensitive opticals of the optical aiming device, e.g. by at least one force absorbing member.

Abstract: A pressure vessel 1 with an output arrangement 5, primarily for use with pulp bleaching using peroxide at high temperature and high pressure, comprising a pressure vessel housing 1, a first end 2, as well as an output arrangement 3 at a second end, whereby the output arrangement 3 comprises an output scraper 4 with at least one scraper arm 5, as well as at least one cleaning member 6, a driving arrangement 7, a driving axle 8, a bearing 9, a supporting structure 10 for the driving arrangement 7, a normally open first outlet 11, as well as, preferably, a normally closed second outlet, whereby the first outlet 11 and the second outlet 12 are provided in the wall 1 of the pressure vessel.

Abstract: A method and a device for holing an oblong member, particularly a guard rail, substantially directly in front of a hole in a second member, particularly a pole, by utilizing a punching device comprising a punch and first and second pressure means with different ratios, of which the first means causes the punch to abut the oblong member, and the second means effects further movement of the punch to carry out holing in said member.

Abstract: Platforms for bottom casting are prepared prior to the casting operation by charging hollow bricks into a mobile loading member shaped in conformity with the pattern formed by the platform channels and by transferring the bricks to the channels to form runner conduits therein by lowering the loading member bodily into the channels and releasing the bricks onto the channel bottoms.
