March 16, 1978 1561564 UK Non-Return Hot Water Diving Suit
June 23, 1981 4,274,759 US Non-Return Hot Water Diving Suit
ABSTRACT: A non-return hot water diving suit in which hot water is supplied to keep the diver warm is exhausted from the suit through a single outlet valve, readily accessible to the diver. In the event of failure of the hot water supply the valve can be quickly closed, trapping the existing hot water in the suit and extending the length of time available for the diver to return to safety. In the preferred form the valve is combined with a flow controlling baffle, which will allow normal hot water outlet flow, but inhibits sudden or rapid intake of cold water through the open outlet.

August 14, 1984 4,464,795 US Easy Access Underwater Diving Suit
ABSTRACT: An easy access underwater diving suit in which the torso portion of the suit is longer than a diver’s torso height and that has a diagonal zippered opening in the upper front portion from shoulder to opposite hip to provide a maximum, easy access opening. After the diver is inside the suit, the torso portion of the suit is adjusted to the height of the diver. A fastening arrangement holds the suit in the adjusted condition.
March 25, 1985 4,502,817 US Air Inlet Valve for Underwater Diver’s Dry Suit
ABSTRACT: An air inlet valve for an underwater diver’s dry suit including a restricted opening in the air inlet coupling on the air inlet hose whereby the air inlet hose acts as a plenum chamber. A valve member is opened to pass the air in the inlet hose to the interior of the suit with a burse. Due to the restricted opening, air can be exhausted from the suit faster than it is introduced and thus avoiding a blow up in the suit, thereby bringing the diver to the surface causing a serious accident.
October 22, 1985 4,547,904 US Survival Suit
ABSTRACT: A wet type survival suit, particularly useful for oil rig workers or pilots and crew members stranded in water, includes an outer layer of material including a sheet of breathing material sandwiches between layers of fire protection material, a middle layer of insulation material that provides flotation, and an inner layer of fire protection material. This arrangement protects against fire, allows perspiration to evaporate, and allows the user to float in water. Suit adjusting laces are provided to adjust the suit to a comfortable configuration for the user. Zippers close the suit to a tight fit for use in water and can be loosened to reduce the restriction when desired.
