On the basis of the formulas of time associations and time periodicity an alternative time algorithm is produced, at a replacement of the numerical values of these years with the numerical values of their periods and their annual two-digit residues, the alternative algorithm may be used in the computer equipment. In the periodic time chart the code symbols are made in the form of squares, whose angles correspond to 4 years, one of which is a leap-year. Seven such squares make up a time coded net equal to one period of 28 years. Each angle of the square is the year corresponding to it with its own coded annual calendar, with its own code symbols-pentagons and squares.

Title: Downhole shock absorber with crushable nose
Inventor: COGHILL ANTHONY S
IPC: E21B17/07
Filed: 2009-03-19
Granted: 2013-11-14
Abstract: A downhole shock absorber preferably is filled with well fluid in a chamber that is reduced in volume due to impact. A rupture disc can hold the initial non- compressible liquid charge until impact. Upon impact, the rupture disc breaks to allow the fluid to be forced through an orifice to absorb some of the shock that occurs when a string hits a fixed object after dropping in the wellbore. The nose of the shock absorber is a soft material that has voids so that the combination of the softness of the material and the voids allow the nose to reshape until it encounters a surrounding tubular wall and then to collapse inwardly into the voids, making it simple to remove. The nose is releasably mounted to the shock absorber so the two can separate if the nose gets stuck after impact.

Abstract: FIELD: medicine; medical engineering. SUBSTANCE: method involves applying mechanical body skin treatment. Electromyographic examination is carried out before beginning the treatment for determining functional state of dorsum muscles. Then bandage is applied. The bandage is a ribbon bearing blocks with cylindrical protrusions having hemispheric surface at the top. The bandage is brought over both suprabrachial zones through axillary areas crossing it in interscapular area placing the protrusions on the frontal surface of the brachial articulations. Electromyographic examination is periodically carried out. The area subjected to block protrusion action is determined from increased bioelectric activity of dorsum muscles. It makes 70-90% when compared to the initial value. Time required for wearing the bandage is determined from stable increase in electromyographic values by 40-50% relative to the initial level. The bandage for treating degenerative dystrophic diseases and traumas of the vertebral column has fabric ribbon having blocks fixable thereon. The blocks have two halves on the working surface of which cylindrical protrusions with hemispheric surface at the top are uniformly spaced. One half of the block has latch. Triangular protrusions are spaced over the surface of the other block half-adjacent to the ribbon.
