Abstract: The present disclosure is directed towards a marine vessel comprising a bow section, a stern section, a centreline and a planing hull. The planing hull comprises a vee bottom section extending along the centreline from the stern section to the bow section and a pair of retainer walls extending from the stern section towards the bow section along either side of the vee bottom section. Each retainer wall extends downwardly parallel to, or at an acute angle to, the centreline. The vee bottom section is configured to, in use, direct water outwardly from the centreline towards the retainer walls. The retainer walls are configured to downwardly direct said outwardly directed water for providing lift to the marine vessel.

Abstract: An inhalation device for use with an inhaler is disclosed. The device includes a dispersion chamber constructed for fluid communication with the inhaler and a suction chamber of variable internal volume in fluid communication with the dispersion chamber. The internal volume of the suction chamber can be increased during use, producing a negative pressure in the dispersion chamber, thereby drawing a substance to be inhaled from the inhaler into the dispersion chamber for subsequent inhalation.

Abstract: An inserter for the positioning of an intrauterine device in the uterus, which inserter includes a plunger, a handle attached to the plunger, a string for the removal of the IUD, a locking device to lock the string in such a way that the IUD remains immobile in relation to the plunger, and a protective tube around the plunger. The protective tube is arranged in relation to the plunger in such a way that it can be pushed, at the forward end that goes into the uterus, past the plunger at distance (L) , which corresponds substantially to the length of the IUD assembled for insertion. The stop members ensure that the front edge of the protective tube is stopped in a configuration in which the hemispherical tips of the wings of the transverse member of a T-shaped IUD remain partly uncovered by the protective tube, but the wings nevertheless remain pressed against each other.

Abstract: A variable magnification scanning optical system for a copying machine includes a lens (10) for projecting an image of an original document (2) with a pre-selected magnification onto a moving imaging member (6). The scan speed may be varied relative to the speed of the imaging member to alter the magnification in the scan direction. To this end a reference signal is generated which is derived from the imaging member and is indicative of the nominal pre-selected magnification. A second signal is generated indicative of the scan speed and the scan speed is varied, e.g. by a servo system (see FIG. 2), until the second signal matches the reference signal. To compensate for tolerances between the nominal magnification and the actual magnification, the reference signal may be adjusted by applying an offset value (23) stored in the memory. This offset value may be entered into the memory by an operator via a keyboard panel (22).
