Abstract: The present invention relates to a hull construction for a vessel, especially a drilling and/or production vessel for hydrocarbons. The invention also relates to the application of the hull construction according to the invention. The invention is especially related to designing hulls for single hull ships which are provided for carrying our operations at sea, and especially vessels which are used for drilling petroleum wells, and for intervention and maintenance of this type of well. With the invention, the aim is to provide a hull shape for a vessel which makes the vessel especially well suited for realising these types of well operations in deeper waters and at sea, and so that the vessel can be operative even under difficult weather conditions which are created by waves, ocean currents and winds.

Abstract: The drive arrangement for the two-cycle engine employs a multi-lobe cam and piston rods which are reciprocated in a rectilinear manner. A roller is mounted on each piston rod to contact and be driven by the multi-lobe drive cam off the drive shaft of the engine. Each lobe of the drive cam is of non-symmetrical shape so that ignition is timed to take place prior to the full extension of the piston rod into an associated combustion chamber.

Abstract: A method is provided for determining at least one of the coefficient of lift and the coefficient of drag of a golf ball for a given range of velocities and a given range of spin rates from launch. A method is also described for simulating the flight of a golf ball in a computer. A ball is launched at a selected velocity, spin rate and launch angle. Calculations are made of the x and y coordinates of the ball during flight and the coefficients of lift and/or drag are calculated mathematically in dependence on the launch velocity, spin rate, angle and calculated x and y coordinates. Repeated launchings are made to obtain a plurality of mathematically calculated values of the coefficient(s). Thereafter, an aerodynamic model for the flight of the ball is mathematically determined in dependence upon the mathematically calculated values of at least one of the coefficients relative to the velocity and spin rate.

Abstract: A filling machine employs a rotary table with a plurality of peripheral openings for receiving bags for filling with particulate matter as the table rotates. A gathering and severing unit is provided on the table in order to close the bag after filling. This unit includes a pair of guide plates which serve to gather a part of the bag when the guide plates are moved towards each other. In addition, a reciprocally mounted severing blade is positioned on one of the guide plates and is reciprocated transversely of the movement of the guide plates in order to sever the gathered part of the bag. The blade may be reciprocated twice to ensure complete severance of the gathered part of the bag.

Abstract: The housing of a hinge assembly is provided with elongated apertures and a plate of less width than the housing is clamped over the apertures by mounting screws which secure the housing to a cabinet. The housing wall and the surface of the plate are serrated to secure the plate against lateral movement after being clamped to the housing. A cover is snap-fitted onto the housing to seal off the elongated apertures and to eliminate any exposed gaps.

Abstract: A clear crystalline faceted substrate is provided with a coating of a colored transparent ink in order to enhance the appearance of the otherwise inexpensive gem stone.
