摘要: Mask includes support member with head band arranged horizontally to fit head of wearer. Conduit sections are secured to each side of support member, and flexible ventilation conduit is connected to exhaust means. Transparent face plate is held to support member in spaced relation to wearer's head. Aperture means in conduit allow ingress of air, and exhaust means connected to conduit sections exhaust air from ventilation conduit and interior of mask. In one form, means in upper portion of face plate admit airflow and direct it down over inner surface of face plate to prevent fogging. Hood of air-impermeable material fits over head and shoulders. Gown of similar material over body and lower part of hood and tied at neck completes assembly. Any leakage is that of sterile air from exterior to interior of mask because of continuously operating exhaust system.

摘要: A pneumatic brake system for a tractor-trailer vehicle incorporates a double check valve within the tractor brake system which functions to quickly port air to the trailer brake system to improve brake response of the vehicle. The double check valve incorporates a cage member suspended within a bore in the valve housing in combination with a spring biased detent mechanism arranged in such a manner to dampen oscillations of a ball valve member within the cage member thereby permitting air to flow unimpeded through the check valve.
