Abstract: FIELD: fire-extinguishing equipment. SUBSTANCE: fire-extinguishing gun has dissipating member positioned behind gun nozzle outlet cut at compact flow path and formed as oval-shaped streamlined body or ball, i.e. edgeless body. Practically effective curvature radius of oval surface faced to nozzle cut may be changed, but maximum fog forming effect is reached, if curvature radius is 1.2-3 times as large as nozzle radius. When this ratio is reduced to 0.5, volumetric part of fog in dispersed spray beam is reduced to 0.5, and spray beam hitting range is increased. Such construction allows compact water jet to be dispersed so as to form finely dispersed foglike spray beam at reduced average pressures of 0.2-0.4 MPa in the regions downstream of gun. Natural water basin with contaminated water may be used as water source. EFFECT: simplified production, enhanced reliability in operation and convenient maintenance and operation. 1 dwg

Granted: 2000-04-27
Abstract: FIELD: digital processing of voice signals, which are transmitted through communication lines. SUBSTANCE: method involves detection of adjacent high-level doubled (having opposite signs) leaps in level of first derivative of voice signal by means of storing previous piece of voice signal, measuring mean absolute value of first signal derivative during this piece by means of accumulation of absolute values of difference between two adjacent PCM signal samples and setting two identical adaptive opposite-sign thresholds which are proportional to mean absolute value of first derivative. If two adjacent PCM signal samples exceed thresholds, anomalous digital error is detected and corrected by means of alternating inversion of high-order bits of PCM code, until doubled leaps of first derivative are removed. EFFECT: decreased requirements for noise protection of communication lines, decreased cable cost, or increased length of retransmission lines, or increased relative number of pairs to be compressed in cables, while keeping constant subjective perception quality of voice. 4 dwg

Granted: 2001-04-20
Abstract: FIELD: power-plant engineering; operation of gas-and-hydro-jet propulsors; generation of power; operation of devices pumping-out water in an emergency. SUBSTANCE: method consists in delivery of sea water and combustible gas to working cylinder which is profiled in shape terminating in nozzle. Water is admitted to working cylinder when it is filled with rarefied gas-and-water mixture. Water moves towards nozzle (towards lower pressure) freeing space behind it in working cylinder and combustion gas is admitted to this space where it expands simultaneously compressing and expelling the previous gas-and-water mixture through nozzle, thus creating the reactive thrust. Then, combustible gas is mixed with remaining sea water forming the gas-and-water mixture which creates rarefaction in cooling, thus admitting sea water and hot gas into working cylinder. Gas may be adiabatically expanded in power turbine. Sea water and hot gas may be admitted to cylinder in turn through revolving spool valve. Sea water may be admitted to working cylinder through hydraulic pulsator entrapping the hot gas. EFFECT: enhanced efficiency of shipboard power plant. 5 cl, 1 dwg
