Abstract: FIELD: medicine; medical engineering; prosthetics; prosthesis engineering. SUBSTANCE: as first link of articulated joint is rotated clockwise, there arises tangential force caused by existence of force generated by stretched resilient member. The latter force generating countertorque causing anticlockwise rotation of locking wedge. As a result, drum is made to slip over wedge. If attempt is made to turn first link of articulated joint anticlockwise, joint is locked so that rotation of first link of joint in relation to second link of joint becomes impossible. In relieving charge striving to turn first link of joint in relation to its second link anticlockwise, to unlock kinematic joint, suffice it to apply to resilient member force that is greater than force of stretching resilient member. When this force is applied locking wedge after turning anticlockwise in relation to axis ceases to contact drum and to make obstacle to its rotation in relation to axis of articulated joint in any direction. EFFECT: stepless locking of imitator of finger joints unbent over entire range of their bending movements; unobstructed and noiseless unlocking of finger joints after relieving gripping charge. 1 dwg

В подземную галерею бурят контрольную скважину. Ее оборудуют термодатчиком для контроля температуры в галерее. Затем осуществляют закачку пара в скважины с поверхности. Ее ведут до начала резкого повышения температуры в галерее. После этого закачку пара прекращают и ведут отбор нефти из указанных скважин до тех пор, пока дебит скважин по нефти не достигнет минимально рентабельного уровня. В дальнейшем циклы закачки пара и отбора нефти повторяют. При повышении температуры в подземной галерее до 90 o С осуществляют закачку воды через контрольную скважину.
