A multi-foil lift force creator (1) for a fishing trawl is disclosed, said multi-foil lift force creator comprising a plurality of hydrofoil elements (2) aligned in a stacked manner and designed to be arranged between and attached rigidly at both ends to a spherical buoyancy element (9) for being mounted on a fishing trawl head rope (11), wherein the hydrofoil elements are shaped to deflect the water during towing of the trawl net (12) in such a way that the hydrodynamic force thereby created complements the buoyancy force from the buoyancy elements, and wherein, rather than having butt ends, the hydrofoil elements join smoothly to multi-foil end caps (5) fitting tightly around the two buoyancy elements at the ends of the multi-foil lift force creator, respectively. Furthermore, a multi-foil lift force creator assembly comprising such a multi-foil lift force creator and the use of such multi-foil lift force creator assemblies during trawling operation are disclosed.

A unattached traffic bollard (1; 101; 201) is disclosed comprising an elongated upright part (2; 102; 202) and a base part (3; 103; 203) arranged to be placed onto the underlying surface, wherein the upright part is arranged to be releasably mounted onto the base part from the top side thereof.
摘要:
A flow booster (8) is disclosed, shaped as a thick hydrofoil with an internal cavity (32), being aerodynamically inefficient on its own with a bulky relative thickness larger than 24 %, and being arranged to be positioned substantially below the rear part of a trawl door (37) comprising an overlapping sequence of several very slender hydrofoils (2), in such a way that the flow booster (8) forms a structurally connected integrated part to the hydrofoil (2) and impacts the upstream flow forcing it into a velocity boosted region (28) upstream of the flow booster (8) and to the pressure side (31) of the conventional part of the trawl door (1), such that the flow is pre-accelerated prior to running through the conventional trawl door channels (29) between the hydrofoils (2). Furthermore, a trawl door (39) comprising such a flow booster (8) and some uses of such a trawl door is disclosed.

A pump crane for a slurry wagon or trailer (1) is disclosed, which is mounted on the slurry wagon or trailer by means of a turntable and comprises a crane arm with a plurality of intermediate parts (12, 15, 16) connected by knuckle joints (13), piping from the turntable to a hydraulic pump head (5) arranged at the outermost end of the crane arm, means for swinging, raising, lowering, unfolding and folding the crane arm, and means for pumping slurry through the piping to or from the pump head, wherein one or more of the intermediate parts comprise telescopic joints (9) so that the length of the intermediate part(s) can be varied, the piping from the turntable to the pump head is double, and solid pipe sections forming part of the piping and having substantially circular cross-sections, constitute the supporting part of the telescopic joints. Furthermore, a slurry wagon or trailer (1) comprising such a pump crane is disclosed.
摘要:
A power tool adaptor for holding a tool adapted thereto including an adaptor body, a tool insertion cavity formed in an end of the adaptor body for receiving the tool, an elongated tool bit insertion cavity formed as a continuation of the tool insertion cavity, means for fixating the tool by protruding into one or more fixation recesses on the outer surface of the tool and means for attaching the power tool adaptor to a power tool; a reversible tool bit holder is further disclosed for holding two changeable tool bits, which reversible tool bit holder is adapted to fit into the power tool adaptor, along with a kit including a power tool adaptor and a reversible tool bit holder adapted to fit into the power tool adaptor.
摘要:
A method for estimating and correcting or at least reducing phase errors in received ultrasonic signals in an ultrasonic flow meter is disclosed, said method comprising the steps of: measuring one or more signals in the ultrasonic flow meter, which one or more signals depend on characteristics of one or more ultrasonic transducers in the ultrasonic flow meter, using the one or more measured signals for calculating an estimated phase error value, and using the estimated phase error value for correcting transmission times measured by the ultrasonic flow meter.
摘要:
The present invention relates to a scraping roller (1) for scraping the skin side of an animal pelt, said roller comprising a plurality of teeth (10, 20, 30, 40, 50, 60, 70, 80), each tooth comprising a scraping edge (11, 21, 31, 41, 51, 61, 71, 81) having a vertex (12, 22, 32, 42, 52, 62, 72, 82), wherein the axial position of the vertex (12) of the scraping edge (11) of a first tooth (10) has a minimum axial distance from one end (2) of the scraping roller and the axial position of the vertex (52) of the scraping edge (51) of a second tooth (50) has a maximum axial distance from said one end (2) of the scraping roller, and wherein at least one of said plurality of teeth (20, 30, 40) is situated intermediate between said first tooth (10) and said second tooth (50) and at least one of said plurality of teeth (60, 70, 80) is situated intermediate between said second tooth (50) and said first tooth (10), these intermediately situated teeth (20, 30, 40, 60, 70, 80) being formed so that the axial position of the vertex of the scraping edge of successive teeth varies gradually between said minimum distance and said maximum distance.
摘要:
A dose delivery device is disclosed wherein a dose can be set by rotating a dose setting member, whereby a push button (4) is elevated from one end of the device a distance proportional to the set dose from a position fixed relative to the housing, and wherein the set dose can then be injected by pressing the push button back to its non-elevated position, through which motion a piston rod will move approximately the same distance. The invention provides a method of forcing a numbered scale drum to rotate both during dose setting and injection to allow the user to read the remaining dose at any time during setting and injecting a dose.
