    摘要： A projection objective for imaging an object arranged in an object plane of the projection objective into an image of the object lying in an image plane of the projection objective has a multiplicity of transparent optical elements and holding devices for holding the optical elements at prescribable positions along an imaging beam path of the projection objective. Each of the optical elements has an optical useful region lying in the imaging beam path and an edge region lying outside the optical useful region. At least one holding element of the holding device assigned to the optical element acts at the edge region in the region of a contact zone. At least one of the optical elements is assigned a diaphragm arrangement with a false light diaphragm arranged directly upstream of the optical element and a second false light diaphragm arranged directly downstream of the optical element. Each of the false light diaphragms is fashioned in such a way that the false light diaphragm screens at least a part of the edge region against radiation running outside the imaging beam path.

    摘要： In the art of acoustic well sounding a gas-gun for the sudden discharge of a measured quantity of compressed gas, comprised of two chambers, viz. a discharge chamber closed at one end by a poppet, and on the opposite end by a power-head, the latter a cylinder including a sealed piston, with the poppet connected by sealed piston rod penetrating the cylinder head, and terminated at the piston. The entire assembly to be so proportioned that regardless of the position of the piston a gap remains between the piston and the cylinder-head penetrated by the piston rod. Means for connecting this gap to the inside of the discharge chamber through a check valve permits gas flow from the discharge chamber to the gap, but not in the reverse direction, and means for venting the gap to the atmosphere. A passage from the opposite side of the piston to the axial outlet of the discharge chamber, a spring or a positive locking device for pressing the poppet against the valve seat. The entire construction is limited by the requirement that the piston rod be smaller in diameter than the seat diameter of the poppet, and the latter to be smaller than the diameter of the piston.
