PURPOSE:To enable responsive power transmission without slippage, improve the durability of a V-belt, and remove the sense of incompatibility at the time of speed change on restarting by driving a speed change motor in line with the change gear ratio of a pulley, when braking is removed or a throttle is opened after quick application of braking. CONSTITUTION:After quick application of braking is d...

PURPOSE:To carry out rapid speed change at the time of quick application of braking while enable responsive power transmission without slipping at the time of restarting, improve the durability of a V-belt, and remove the sense of incompatibility at the time of speed change by operating a speed change motor at the same time as the quick application of braking. CONSTITUTION:The position of a movabl...

An apparatus for the high-frequency artificial respiration of living animals or human beings has a flexible endotracheal tube for introduction into the trachea thereof. The flexible endotracheal tube has an outlet end, a valve at the outlet end and control and air supplies along the endotracheal tube to the valve. The control operates the valve to produce steep-flanked respiratory-air pulses. The ...
