| 161 | Float type breathing device for diver | JP2735581 | 1981-02-25 | JPS57140290A | 1982-08-30 | HAYAZAKI TADAO |
| PURPOSE:To improve the safety in diving by providing a floating body with inhaling and exhaling pipes in such a manner that the pipes pass through the inside of the floating body and that an inlet and an outlet of the pipes are always held in predetermined positions above the water level, so that water is prevented from coming into the pipes. CONSTITUTION:By using singular or plural hollow daughnut shaped floating ring(s) 2 of flexible synthetic resin provided with plugs 1 for inhaling and exhaling, a floating body 14 is formed to have a top surface cover 11. An inhaling pipe 15 and an exhaling pipe 16 are provided in such a manner that they pass through the inside of the floating body 14. The bottome ends of the inhaling pipe 15 and the exhaling pipe 16 are connected to a diving mask 28, while the top ends of the same are made to project above the floating body 14 and bent downwards to constitute inflow-preventing pipes 21 and 21' with an inhaling and an exhaling parts formed at the ends of these pipes. Accoding to this arrangement it is possible to prevent water from flowing into the inhaling and exhaling pipes 15 and 16. Since the floating body 14 can be collapsed by deflation, it can be transported and stored easily. | ||||||
| 162 | Air filter for diving | JP12491780 | 1980-09-08 | JPS5751597A | 1982-03-26 | TAURA TATSUMI |
| PURPOSE: To proide avoidability of pure air in which minut particles supended in lubricating oil and affecting badly the divers are completely elimiated by arranging an oil filter to eliminate minute particles on oil in the air and a wate filter in the air- sending circuit. CONSTITUTION: Filter 2 is connected through a tube to compressor 1 and dusts and the like in the air, are eliminated through this filter 2. Further, after the minute particles of oil is eliminated by an oil filter 3, the air is sent to a diver through a water filter 5. The oil filter 3 gushes out the supplied air into the water through an air dispersing nozzle 3d and generates numerous small bubbles. Thus the minute particles of lubricating oil in the course of sending the air are eliminated by using water or medicinal fluid in the filter 3 when thses small bubles are moving upward.

| 163 | Simplified rescue diving equipment | JP128880 | 1980-01-11 | JPS5699892A | 1981-08-11 | ITOU FUMIO |
| PURPOSE: To achieve the safety of working under water by securing a position feeding of air to a worker as driver by introducing to the worker the air taken in from an air-inflated flat bag provided with an air intake and a path for introducing air. CONSTITUTION: An air inflated flat bag in made spherical comprising upper and lower sections. The upper half serves to separate air from water while the lower half constitutes an air bag provided with an air injection inlet 6. A plastic tube runs through the center of the float bag from the upper to lower end thereof and a tapped hole 7 for mounting a radar reflecting net is provided at the uppermost section. Air is sent to a diver through a hose fitted with a check valve after passing through a waterproof cylindrical section 3 from an outside air intake and then, through the plastic tube from an intake 4. A weight is provided at the bottom of the flat bag to prevent turning thereof sideways. COPYRIGHT: (C)1981,JPO&Japio | ||||||
