Abstract: FIELD: finishing of high-precision inner surfaces of rotation. SUBSTANCE: inner surfaces of rotation are finished by a fixed abrasive tool, whose mandrel axle is installed proceeding from the condition of intersection at acute angle α of the axis of finished hole. The mandrel is linked with the spindle by means of a hinge for fixing their position. Angle α is originally determined proceeding from condition α = arcsin[(D-d n -2c)/(2l o +H)], and then, with wear and dressing, it is periodically changed to α = -arcsin[(D-d n -2c)/(2l o +H)],, providing the non-repeating trace principle, where D - diameter of finished hole; H - height of abrasive wheel; d n  - hinge diameter; C-guaranteed clearance between spindle and finished hole; l o  - mandrel length. The wheel has two flats diametrically arranged at distance B = 2[D 2 /4-(0,5Htgα+c) 2 ] 0,5  from each other, parallel to the plane of turn at a change of angle α, for cleaning the wheel of chips and mud.

Filed: 1996-09-27
Granted: 1997-11-20
Abstract: FIELD: biology; medicine. SUBSTANCE: patient is first subjected to scanning in order to localize area to be treated and to obtain positive pulse. Therapeutic effect is caused by mentally concentrated radiation emitted at frequency 2.5-5.0 MHz, wavelength 60-120 m, focused first on center of functionally affected organ, and next upon entire organ for 20-80 s. Cure is achieved by applying right hand's palm onto projection of affected organ, namely: palm is applied first in parallel to patient's body (frequency 0.15-1.5 MHz, wavelength 200-2000 m, power density at least 0.15 mWt/sq.cm) and, next, palm is placed "on rib" (perpendicularly) to patient's body. Hand's palm is held in this position until appearance of elevated temperature in affected zone or until disappearance of muscular contractions therein. If hand's palm is placed "on rib", radiation is emitted at frequency 1.5-2.5 MHz, wavelength 120-200 m, power density at least 0.15 mWt/sq.cm. In case of acting with "on rib" placed palm, therapeutic session must last as long as body temperature is charged in affected area or parasthesia appears therein in form of vibrations or slight movements. EFFECT: method permits to preliminary detect area in patient's body for subsequently subjecting it to sparing treatment.

Abstract: Изобретение относится к судостроению и касается парусных систем с жесткими парусами для судов различных классов. Каждый жесткий парус имеет несимметричный аэродинамический профиль. Изогнутые боковые поверхности противоположных парусов каждой их пары расположены параллельно. Эти паруса соединены общим реем. Он установлен на мачте, имеющей возможность вращения вокруг вертикальной оси. Центральный участок рея снабжен элементом привода его вращения. Механизм подъема и опускания жестких парусов выполнен в виде механизма наклона мачты или ее верхней части вместе с парусами. Привод вращения общего рея может выполняться в виде реверсного двустороннего гидроцилиндра. В нем находится поршень с зубчатой поверхностью, находящейся в зацеплении с шестерней в центральной зоне рея. Его привод вращения может выполняться и в виде тросовой системы со звездочкой. Она может крепиться в центральной зоне рея и через трос соединяться с лебедкой, имеющей реверсный электродвигатель для ее привода. Способ эксплуатации этой парусной системы характерен тем, что при переводе парусов из рабочего положения в нерабочее вращают мачту. Плоскости, проходящие через хорды парусов, размещают параллельно продольной оси судна. Затем наклоняют мачту или ее верхнюю часть вместе с парусами до размещения кромок парусов на палубе. При смене галса рей с парусами вращают на 180 o  его приводом и вращают мачту вокруг ее вертикальной оси, устанавливая положение парусов с учетом курса судна и направления ветра. Технический результат реализации изобретения состоит в упрощении конструкции узлов парусной системы и повышении эффективности ее эксплуатации путем автоматизации рабочих операций системы. 2 с. и 10 з.п.ф-лы, 12 ил.
