Abstract: A device for direct, visual estimation of dimensions of measurement objects that are difficult to reach, such as organs and foreign articles within human and animal bodies. The human eye gives a good size apprehension when comparing a measurement object with a similar thing of known dimension close to that of the measurement object. The comparison can be carried out on an X-ray picture in which a measurement object as well as a comparison body are reproduced close to each other and on the same scale. Means are provided for fixing the comparison body at the exterior surface of the human or animal body. The comparison body is confined by a series of surfaces of revolution with different sizes within an interval matched to the dimension interval of the dimension object.

Abstract: In an internal combustion engine with spark ignition and one or more reciprocating pistons, with an ignition device positioned in a roof-shaped top face of the combustion chamber and at least one fuel delivery device for each cylinder for direct fuel delivery essentially in the direction of the ignition device, and with at least one intake port configured so as to generate a swirl movement, the piston exhibits an asymmetrically shaped piston recess whose walls are configured as arcuate flow guiding faces assisting the swirl movement of the cylinder charge. To obtain reliable ignition of the directly introduced fuel on the one hand and maximum liberty in designing the engine on the other hand, the proposal is put forward that the piston recess between opposite walls should essentially constitute an open channel of meander-shaped or S-shaped configuration in plan view, at least one end of the channel forming an inlet area into the recess, which starts at the piston rim.
