摘要： It has been discovered that high amplitude, low frequency, broadband spectrum pressure oscillations of sufficient time duration can help stabilize lung volumes and improve gas exchange in a patient receiving ventilation assistance by helping to recruit and stabilize alveoli. A novel device is presented which can produce pressure oscillations having high amplitudes, a low broad-band frequency spectrum and long time duration. Additionally, the device can maintain a patient's mean airway pressure at one or more controlled levels. The device can control the oscillatory amplitude, frequency range and composition, time duration, and mean airway pressure levels by adjusting certain device parameters, such as the angle and depth of the device in a fluid. A device and mechanical system for remotely adjusting and measuring the angle of the device in a fluid are also disclosed. Furthermore, a device and system are disclosed that can deliver pressure oscillations having high amplitudes, a low broad-band frequency spectrum, long time duration, and multiple mean airway inspiratory and expiratory pressure levels. The device and system also provide means for controlling respiration timing in a patient, including: breaths per minute, inspiratory time, and the ratio of inspiratory to expiratory time.

摘要： A gravimetric system for feeding flowable, solid, particulate materials includes an open-topped trough receiving the material from a hopper at one end and discharging it from the other end at a desired rate in terms of weight per unit of time. The trough is formed in two, longitudinally aligned and continuous sections with a rotatable auger extending through the hopper and trough to move the material from the hopper to the discharge end of the trough. The first trough section is fixedly supported and the second section is supported at two spaced points on each side in an essentially frictionless manner by contact of pointed terminal ends of upwardly extending pins with conical recesses in blocks affixed to the sides of the second trough section. One pair of supports, one on each side of the second trough section remote from the end adjacent the first section, is connected to a load cell, whereby the weight of material in this portion of the trough is reflected in an electrical signal which controls the auger speed to adjust the rate of material feed to the desired discharge rate.
