Abstract: Invention concerns to underground construction and can be used at maintenance of capital mine workings on big depths.        Technical result of the invention is maintenance of stability of mine working at their location on depth of 600-1200 m. In working face is carried up a yielding support and simultaneously inject in the lining space a friable mix of a cold bitumen-mineral material of thickness of 250-450 mm. Then in 8-12 days forcing a liquid mix of a bitumen-mineral material is made into the elastodeformed zone under pressure 1,5-3,0 atm. The method is effective both for the strong form of section of mine working and for round one. Presence in the lining space of a viscous-plastic environment from bitumen-mineral material improves interaction of a construction of a support 1 with a rock mass owing to uniform distribution of active forces and creation of uniform system of support file.      2 figs.

Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE.        To provide for a space-saving, yet high-capacity storage system for sheet elements, for example folded printed paper sheets or the like, a plurality of segments (6) are slidable along a guide track.  The segments are interconnected, for example by welding, hinges or the like, in zig-zag or accordeon pleat  form.  When compressed, the structure can be empty and any number of segments can be taken from an empty storage region, transported to a loading/unloading/mixing region for insertion, removal, or interleaving of sheet elements, while the segments are in expanded position; and then, again, compressed so that sheet elements or folded sheets will continue to be carried in the structure formed by the segments, with little space required.  For interleaving or intermixing of sheets, folded or single sheet elements, two such zig-zag carrier structures can be located adjacent each other or above each other, and by spreading apart the segments which may be in U-shape, two paired lateral   elements  supported on divergent rails or the rail, permit dropping of sheets or sheet elements from an upper segmental array into a lower one or, if located adjacent each other, permit   gripping of sheet elements in one array and lateral transport by grippers to an adjacent one.

Title: Method and apparatus for processing signals used in oximetry
Inventor: SMITH ROBERT E
IPC: A61B5/00
Filed: 1987-08-17
Granted: 1992-04-07
Abstract: METHOD AND APPARATUS FOR PROCESSING       SIGNALS USED IN OXIMETRY        Abstract The present invention relates to the processing of signals containing information about the pulse rate and oxygen saturation of arterial blood flowing in tissue. These signals have a relatively periodic pulsatile component superimposed upon a varying baseline component. To determine the pulse rate and oxygen saturation from the signals, the positive peaks, negative peaks, and period of the signal must be determined. The present invention accomplishes this by first searching for a sustained positive sloping region of the signal. Then the first derivative of the signal with respect to time is analyzedand points on the signal before and after the occurrence of a slope reversal marked. If the slope at the first point is positive, the interval between the two points is searched for a maximun amplitude that is identified as a positive peak. After the occurrence of a negative sloping region of the signal, another pair ofpoints are marked occurring before and after a subsequent slope reversal. The minimum amplitude of the signal between these points is then identified as a negative peak. For improved accuracy, these positive and negative peaks are then compared with waveform templates to determine whether the amplitude between the peaks falls within an allowable range and to determine whether the interval between the peaks likewise falls within an acceptable range. These ranges are adjustable in proportion to the amplitude and interval compared against them. In this manner, values for the positive peak, negative peak, and period of the signal can be determined with high reliability.
