Abstract: The invention relates to a method of preparing a surface to be treated such as a surface to be painted. The surface is initially divided into so-called patches by a method known. Subsequently, the patches are grouped in so-called main faces by the method according to the invention. The main faces are used for defining a number of so-called virtual surfaces, also by the method according to the invention, and the virtual surfaces are used to establish lines of treatment along the surface, such as paint lines, said lines of treatment defining the subsequent motion of the tool for treatment.

Abstract: A display unit for a consumer product such as a compact disk, digital audio tape, cassette tape or video tape. The display unit includes a frame having at least one generally rectangular opening adapted to receive the consumer product therewithin. The opening is defined by parallel top and bottom frame portions joined by parallel side frame portions. The frame has a front side through which the consumer product can be placed in the opening and a rear side opposite thereof. The display unit is also formed such that one of either the top and bottom frame portions or the side frame portions is spaced apart by a greater distance then the corresponding vertical or horizontal dimension, respectively, of the consumer product and the other of either the top and bottom frame portions or the side frame portions is spaced apart by a distance substantially the same as the corresponding vertical or horizontal dimension, respectively of the consumer product.

Abstract: The invention relates to a container for the safe air transport of plutonium having several intermediate wood layers and a load spreader intermediate an inner container and an outer shell for mitigation of shock during a hypothetical accident.

Abstract: The disclosure relates to an apparatus for spin ejecting a body having a flat plate base containing bosses. The apparatus has a base plate and a main ejection shaft extending perpendicularly from the base plate. A compressible cylindrical spring is disposed about the shaft. Bearings are located between the shaft and the spring. A housing containing a helical aperture releasably engages the base plate and surrounds the shaft bearings and the spring. A piston having an aperture follower disposed in the housing aperture is seated on the spring and is guided by the shaft and the aperture. The spring is compressed and when released causes the piston to spin eject the body.

Abstract: The disclosure relates to a mechanism for releasably locking a nose tip to a vehicle utilizing a pawl and ratchet and pinion arrangement.
