Abstract: A method and apparatus is provided to quantitatively characterize a lense or optical system as to best focus position at various locations of the lense as well as to determine the curvature or focal surface, and the relative depth of focus of the various locations. A test vehicle is provided having an array of object groups, each object group being comprised of a small object (12) having a size about equal to the resolution limit of the lense or optical system and a large object (10) having a size substantially larger than the resolution limit of the lense or optical system, the groups being separated by opaque areas. The test vehicle is interposed in the lense path and the focal length set at a position which will resolve the large object but not the small object on an image sensor. The sensor is moved orthogonally with respect to the lense and the focal length changed and the object group projected again on the sensor. These steps are repeated successively until both large and small object images are resolved, and further continued thereafter until only the large object is resolved. A series of large and small images is produced for each object group, and the median point of the small image series for each object group represents the best focal distance for the location of the lense corresponding to that object group.

Abstract: An electrical ground fault detection and limitation system is used for example in a nuclear reactor utilizing a liquid metal coolant, e.g. sodium. Elongate electromagnetic pumps (80) submerged within the liquid metal coolant and support electrical equipment may experience an insulation breakdown occasioning the development of electrical ground fault current. Without some form of detection and control, these currents may build to damaging power levels to expose the pump drive components to the sodium with resultant undesirable secondary effects. Such electrical ground fault currents are detected and controlled through the employment of an isolated power input (120,128,124,122) to the pumps and with use of a ground fault control conductor (163,164) providing a direct return path from the affected components to the power source. The ground fault control conductor is additional to the electrical ground of the nuclear facility. By incorporating a resistance arrangement (160) with this ground fault control conductor, the amount of fault current permitted to flow may be regulated to the extent that the reactor may remain in operation until maintenance may be performed, notwithstanding the existence of the fault. Monitors such as synchronous demodulators may be employed to identify and evaluate fault currents for each phase of a polyphase power and control input to the submerged pump and associated support equipment.

Abstract: In a spatial, non-unwindable bellows, its mechanical rigidity in the direction of extension is appreciably less than transversely to the direction of extension. In a longitudinal section, it has the thinner wall thicknesses in the folding region than the other regions of the bellows in order to prevent the bellows from breaking out perpendicular to its direction of extension. Furthermore, it has rail-shaped bearings (51) located at least parallel to each other, to which the concertina wall parts (53) are connected in a swivelling manner, which bearings (51) form an inner and an outer closed wall when the bellow is closed. Between these walls the concertina wall parts (53) rest on one another. Cavities (55) are thereby bounded which are equilateral triangles in cross-section. This bellows allows the pleasant appearance of the furniture to be kept when the table top is adjusted and, despite this, allows the inner structure to be of optimum design for receiving electric leads and the like. <IMAGE>

Abstract: Machine tools work at ever higher speeds for driving the workpieces or tools. If such a part is flung away from the machine due to a lack of adequate mounting, it has a very high kinetic energy. To protect the operator, protective coverings are necessary which have to be designed to be movable in the area of the workpiece and the tools and also have to be transparent so that the work progress can be observed. If protection is to be provided in the face of the speeds possible nowadays in combination with the possible workpiece or tool weights, steel coverings in the meantime reach a thickness whose dead weight becomes problematic. It is therefore proposed to extend the polycarbonate plates, hitherto used only as sight windows in a steel covering, to the entire covering. On account of the high elasticity of such plastics, polycarbonate coverings of this type are not only thin but in particular are also light so that, apart from a counterhold taking into account the corresponding deformation in the event of being bombarded, no design problems due to a high dead weight occur.

Abstract: In a lock of the kind where a cylinder assembly (4) is slidable as a whole to shift a locking member (14) to its locking position and is retained in that position by a lateral retainer bolt (16) extending into an associated detention (17), a member (13) which carries that bolt (16) is formed separately from the cylinder barrel (5) and plug (6) and is connected to the barrel (5) by screws (25) which will fail when subject to a predetermined load in the unlocking axial direction of the cylinder assembly (4) which is less than that which will cause failure of the retainer bolt (16) or its detention (17). Accordingly, if an attempt is made to attack the lock by forcibly withdrawing the cylinder assembly (4) from its locking position there will ultimately be a preferential failure of the connecting screws (25). Even though the cylinder assembly (4) is withdrawn to what would be the normal unlocking position, therefore, the retainer bolt (16) and locking member (14) remain secure and unaffected.

Abstract: In a communication apparatus comprising a communication path through which a message passes and, a plurality of communication subjects, each of which includes a message transmission function to the communication path, and a read function for reading the message from the communication path, each communication subject maintains a communication cumulative amount table for each communication subject so as to store the communication cumulative amount of messages transmitted by each communication subject as communication history data; the communication subject adds the latest communication cumulative amount in the communication cumulative amount table to a message which is transmitted to the communication path; the communication subject compares the communication cumulative amount table stored thereby with the communication cumulative amount added to the message being received. Thus, troubles of the communication subjects in the communication apparatus according to the result of the comparison can be detected. In addition, without complicated operations of each communication subject, while the overhead of processes is kept low, it is possible to prevent a bad effect due to a trouble or error of communication subjects from being propagated to other communication subjects.
