Abstract: A method of free forging work-pieces in forging presses and a forging tool for carrying out the method. In the known free-forging installations it is often the case that the forging operation cannot be completed in heat; on the contrary, the work-piece (20) has to be reheated. In addition, upon direct contact between work-piece (20) and tool (13, 15), bulges, partly with crack formation, occur in the free side faces, and to correct these bulges transverse upsetting has to be carried out several times while the cooling-down time is prolonged. Consequently, the expenditure of energy is relatively high. It is possible with the invention to reduce this expenditure of energy, with at the same time surprisingly improved product quality, by the material flow in the work-piece (20) being specifically controlled, even segment-by-segment, at any angle to the longitudinal axis of the forging (20), the material flow being controlled by means of specially profiled tools, preferably by appropriately designed top and bottom saddles (13, 14). <IMAGE>

Abstract: Improved activated carbon electrodes are disclosed, which electrodes have increased charge storage capacity. Such improved electrodes are incorporated into energy storage devices such as electrical double layer capacitors. The improved charge storage capacity is due to the adsorption of polyoxometalate compounds into the activated carbon, which compounds are capable of reversible redox reactions and so provide a secondary charge storage mechanism without decreasing the charge storage ability of the activated carbon.

Abstract: A lost motion clutch assembly is disclosed which hasfirst (31), second (32), and third (33) clutch members. The first and third dutch members are mounted coaxially and contain a plurality of recesses (43) in the surfaces facing each other. The second clutch member is disposed between the first and third, and preferably includes a plurality of balls disposed in arcuate recesses in the first and third clutch members. Each recess has two terminating ends (41A, 42A and 41B and 42B) forming engagement shoulders to engage a portion of the balls at the termination of each of the two directions of rotation. Upon initial rotation of the first clutch member in a first rotational direction, the third clutch member is not rotated until a ball has come into contact with the opposite end of the recess in the first clutch member and also in engagement with the opposite end of a recess in the third clutch member. By this means, an additional angle of angular lost motion is achieved for a given number of balls. Only 80 degrees of motion is achieved on the balls relative to one clutch member, but an additional 80 degrees is achieved between the balls and the other clutch member, for a total of about 160 degrees of lost motion, yet three balls are utilised for symmetry and for carrying the load.

Abstract: A receiver for radio broadcasts is proposed which has an analysis circuit for digitally transmitted traffic information. The radio receiver has a memory with road-oriented segments which are subdivided into route segments. For reception of digital traffic information it is sufficient to specify the road, the route segment, and the direction. On the basis of the arrangement in the memory, it is then possible for the receiver to generate the other information itself. This means that the digital data transmission can take place at a high repetition rate. <IMAGE>

Abstract: An optical emission microscopy system comprises a macro optic system (30) having a high numerical aperture for obtaining global views of an integrated circuit device under test (10). The device under test (10) is subjected to illumination and stimulation conditions, and images are obtained to form a "global difference" image in which defects, wherever located in the chip, can be discerned by the system operator. The operator can select apparent "defect bright spots" to be further inspected, and zoom in with a higher magnification micro optics system (40) to repeat the image formation steps. "Difference images" are processed to further eliminate noise spots using an approved two-stage filtering operation. The system may be operated under manual or automatic control, and may be inter­faced to various data input, storage, and output device as desired.
