Abstract: A sealing assembly (4) is used to seal the gap between the two member (1, 2) that move relative to each other. It includes first and second rings (5, 6) provided in a groove (3) formed in one of the members. A portion of the outer peripheral surface of the first ring (5) is in contact with the other member. None of the surfaces of the second ring (6) makes contact with the other member. The second ring (6) engages with the portion of the first ring (5) which is not in contact with the other member. The second ring (6) has a coefficient of thermal expansion smaller than that of the first ring (5). When the first ring (5) expands due to the heat generated by the slide of the first ring (5) against the other member, the expansion of the first ring (5) is limited by the second ring (6).

Abstract: A microprocessor based time-of-use electricity meter register uses an external real time clock powered by a backup battery during a power outage to measure real time elapsed during the outage. Upon detection of a power outage, line power and real time data are transferred by the microprocessor to an external, non-volatile memory, the external real time clock is energized by the backup battery and the clock reset to accumulate elapsed real time (days, hours, minutes, seconds) during the duration of the outage. Upon resumption of line power, the elapsed real time accumulated by the clock and the content of the non-volatile memory are transferred to the microprocessor, the backup battery is disconnected from the external real time clock and the real time previously stored in the nonvolatile memory is updated by the elapsed real time so that no customer billing data are lost during the outage.

Abstract: In a radiographic method, radiation shielding ele­ments (54, 56; 70, 72) are arranged between two radia­tion sources (50, 52; 66, 68) and an image converter (14). When an object (6) is irradiated in a first state with radiation beams (4), from the first radiation sour­ce (50, 66) the radiation shielding elements (54, 56; 70, 72) pass both some of the transmitted radiation beams which are not scattered by the object (6) and transmitted therethrough and scattered radiation beams (8) which are scattered by the object (6) so that a first radiation image is obtained in the form of elec­trical signals based on the transmitted radiation beams and the scattered radiation beams (8) In a second state, when the object is irradiated from the second radiation source (52, 68) the radiation shielding ele­ments (50, 52; 66, 68) pass only some of the scattered radiation beams (8) scattered by the object so that a second radiation image is obtained in the form of elec­trical signals based on only the scattered radiation beams (8). The first and second radiation images are electrically processed to reproduce and display a two-­dimensional transmitted image which is not influenced by spatial variation of radiation-transmittance for the radiation shielding elements and by the scattered radiation beams (8).

Abstract: In a method for identifying anomalous noise amplitudes in seismic records, a measured amplitude factor is derived over predetermined periods of time or time windows for a predetermined number of traces comprising the records. A noise-free amplitude factor for the same periods of time and number of traces is also computed using a Gauss-Siedel method of matrix inversion. A ratio of the measured and noise-free amplitude factors is made to determine a correction factor which is compared to a used defined threshold value for determining a presence of anomalous noise amplitudes in the seismic records. Based on the comparison of the correction factor to the threshold value, the user determines whether to suppress or correct traces experiencing the anomalous noise amplitudes.

Abstract: An outsole construction for a shoe which provides all midsole and outsole functions with a single homogeneous moldable material through geometry alone is disclosed. The invention employs cut-out geometry for engineering various characteristics into an outsole of a uniform, monolithic material. Such characteristics are obtained by removing material or reinforcing the material so that it functions as if it had different densities. The invention is based on the principle of minimum sufficient thickness in order to maintain the foot as close to the ground as possible. Energy absorption/cushioning is achieved in the invention by the following features: (1) a series of transverse slots along the lateral border to provide cushion conformability to the lower foot column; (2) an array of compression columns or holes in the heel region to accept the known pressure distributions; (3) an array of small holes in the ball region to add both cushioning and flexibility; (4) a raised heel cup to constrain the heel fat pad expansion during impact and enhance the natural shock absorbing characteristics of the foot; and (5) relief of the rear lateral heel border to dynamically smooth and cushion initial heel strike.

Abstract: In known grate furnaces, the air slots between the individual grate bars are aligned perpendicularly to the grate surface. The primary air flowing through thus forms jets directed perpendicularly upwards. A new grate bar (4) has been developed, in which the cross-section of the grate bar head (6) has a shape similar to a rhomboid. In a furnace grate, which is equipped with grate bars (4) of this type, the primary air jets emerge at an angle. Surprisingly, it has been found that the utilisation of the primary air is consequently significantly improved. The grate bar (4) is particularly suitable for use in roller grate furnaces of waste incineration installations.
