Title: Emergency escape breathing apparatus
Inventor: SWATTON EDWIN JOHN
IPC: A62B7/02
Filed: 1987-04-10
Abstract: In emergency escape breathing apparatus in which a hood 1 of a heat-resistant material envelopes the head of a wearer, there is provided a closed circuit breathing system in which the recirculating gases are kept separate from a cushion of substantially stagnant air around the head of the wearer. The breathing system comprises essentially a half mask 2 engaging the face of the wearer around the nose and mouth within the hood 1 and a breathing bag 4 carried by the hood 1 or by the half mask 2 or by both. The breathing bag 4, which is protected from hot embers by the heat resistant material of the hood 1, is fed with breathable gas, preferably oxygen, from a source 5, and provides a reservoir of breathable gas in a space separate from the general interior of the hood 1 about the head of the wearer. The breathing bag 4 and the half mask 2 are interconnected by means 7. An inhale valve 8 permits inhaled gases to pass from the breathing bag 4 to the half mask 2 and causes exhaled gases to pass through a carbon dioxide absorbent material 9. The source 5 of oxygen or other breathable gas may advantageously be located within the breathing bag 4 (Figure 2), (not shown). <IMAGE>

IPC: G05D23/275
Filed: 1990-03-26
Abstract: The sauna has a heater 1 with elements 1A1-1A3, 1B1-1B3 to heat a stone space, a heater 2 with elements 2A1- 2A3, 2B1-2B3 for an air duct and a control system operating so that the power demand is always smaller than the total power of all elements. In a first mode, switch 12 is open and initially heater 1 receives full power. elements 2B1-2B3 receive full power and elements 2A1-2A3 are off. When a two-stage thermostat 3, responsive to the stone space temperature, switches its contacts 3A, 3C to position 2, heater 1 operates at half power, elements 2A1, 2A3 are in series and operate at 3 DIVIDED 4 power and elements 2B1-2B3 remain at full power. Thereafter, when contact 3B also switches to position 2, all heaters 2 operate at full power and for heater 1 only elements 1B1, 1B2 are energised. Subsequently, a two-stage air space thermostat 11 opens its contact 11A to deenergise air duct elements and thereafter contact 11B opens to interrupt all power to the sauna. In a second mode used for a short sauna bath, switch 12 is closed causing initial operation of heater 2 at full power and heater 1 at half power. When contact 11A opens, all power is removed from heater 2 and heater 1 operates at full power.
