Abstract: A method and apparatus for representing a processed workpiece in perspective with invisible covered edges on the picture screen of a numerically controlled machine tool includes the steps of resolving both the workpiece and the tool into equidistant sections and storing the coordinates of these sections in a RAM. In correspondence to the relative movements of the tool and workpiece determined by the numerical control program, the associated sections of the tool and workpiece are superimposed in an image point memory. With the aid of a simple algorithm the section contour of the workpiece is altered by the superposition is determined, and its coordinates are stored in the RAM. After this process has been completed for all section planes, all sections are successively fed into the image point memory, with succeeding sections offset by several image points in the X and Z directions with respect to the preceding sections. After each superposition, the algorithm is used to determine the resulting outer contour, which is applied to the display. Covered parts of sections lying in the background are not represented on the display, since they lie inside the outer contour determined up to that time.

Abstract: A multilayer ceramic capacitor characterized by a stack of alternate dielectric layers of oxidic ceramic material and electrode layers consisting of a mixture of a metal having a high electric conductivity and ceramic particles of a material having a sintering temperature which is above the sintering temperature of the oxidic ceramic material of the dielectric layers. As a result of this electrode composition the capacitor can be manufactured by means of a uniaxial pressure sintering process in which the stack is sintered while simultaneously applying pressure in the direction transverse to the plane of the layers. This leads to dielectric layers which are substantially free from pores and have a thickness of at most 20 µm.

Abstract: The shut-off vaive (1, 40, 85) comprises a valve housing (2) having at least two chambers (3, 4, 5) adjoining one another in axial direction. The chambers are communicating with one another through a passage bounded by a valve seat (6,7). A valve body (15) is axially movable in the housing and co-operates with each valve seat for closing the associated passage. The valve body is guided with sealed passages through the walls of the axially outer chambers opposite the valve seat (6, 7). The passages and each valve seat have substantially the same diameters. The valve body can be composed of an upper body and a lower valve body part both being provided with a sealing ring co-operating with the same cylindrical valve seat.

Abstract: @ The improved method of the present invention comprises making selected polyesteres by condensation polymerization of polycarboxylic acids with a plurality of diols, the diols being in a eutectic mixture having a melting point below that of the individual diols in the mixture. Thus, the eutectic mixture is charged in the liquid state with a sufficient amount of the acid and reacted under condensation conditions to form an ester and to polymerize the ester to the desired extent. A substantial saving in the amount of labor necessary to prepare the polyester is provided by the present method. The diols are preferably selected from the group consisting of neopentyl glycol, trimethyl pentanediol, cyclohexane dimethanol, and 1,6 hexanediol. Usually two diols are employed to form the eutectic mixture. They are normally waxy solids at ambient temperature, but are liquid when mixed in the proper proportions to provide the eutectic. Usually the molar ratio of the eutectic mixture of the two diols varies between about 30:70 and about 70:30. One preferable eutectic mixture comprises neopentyl glycol and 1,6 hexanediol in a molar ratio of about 1:1.
