THE SAVOX APPARATUS. This was a short period apparatus designed for a period of wear of only 45 minutes. It comprised an oxygen cylinder, absorbent cartridge, cooling device, reducing valve, pressure relief valve and corrugated breathing tube with mouthpiece attachment.

Background why most divers use OPV's

Sabre developed their SEFA (Selected Elevated Flow Apparatus) in conjunction with Mines Rescue Service. It was UK approved by the HSE in 1985.

Proton rebreather by Siebe Gorman

To ensure immediate oxygen availability, as "Oxylithe" takes a couple of minutes to react sufficiently, an "Oxylet" capsule provides an initial charge of high-pressure oxygen when its seal is broken.

The Novus rebreather from Siebe Gorman was primarily developed for the Siebe Gorman submersible decompression chamber

One of the early minerescue oxygen rebreathers designed in 1906 Information on the Meco-Briggs Breathing Apparatus factual information regarding the Meco-Briggs breathing apparatus: A Landmark Study of Mine Rescue Technology: “Baking a New Technology” John Singleton’s paper, “Baking a New Technology: Breathing Apparatus for Mine Rescue in Britain, c. 1890 – c. 1930,” offers a vital…

The first selfcontained underwater breathing apparatus? In 1825, British inventor William H. James constructed what is widely recognized as the first workable, full-time self-contained underwater breathing apparatus (SCUBA). His new design represented a significant improvement over the surface-supplied air systems of that era, as it allowed the diver to carry their own air supply. The…

The MRS was an adaptation by Siebe Gorman of an oxygen-nitrogen gas mixture self contained diving dress designed by Sir Robert Davis and his son R.W.G. Davis before World War II.

The origin of the Oxilithe technology began with the scientific work of the French chemist Professor Georges Jaubert, who at the beginning of the 20th century discovered that sodium peroxide in solid form offered an ideal solution for enabling breathing in enclosed spaces

Minox Oxygen Breathing Apparatus Specifications The Minox is a one-hour minimum duration, closed-circuit oxygen breathing apparatus developed by Siebe Gorman (p. 5). Its key innovation is a compact, efficient flow control unit that replaces the conventional reducing valve, simplifying initial check procedures (pp. 5-6). The apparatus is back-worn, housed in a tough moulded glass fibre…

The very beginning It is surprising how few people know who discovered photosynthesis, considering that without it, we wouldn’t have the oxygen we need to survive. In 1779, a Dutch doctor named Jan IngenHousz changed everything. Through a series of clever experiments in London, he proved that plants need sunlight to create the “good air”…

Sleeping Beauty, Another underwater apparatus Christian Lambertsen helped advance was the motorized submersible canoe, nicknamed: Sleeping Beauty.The ‘Sleeping Beauty’ submersible canoe was built by the British SOE to hold a single frogman to conduct clandestine reconnaissance or attacks against enemy vessels. It earned its nickname when a British officer walked past the canoe and found…
