Abstract: PURPOSE:To improve the safety of a solid fuel feeding device by constituting the device with a piston-cylinder combination and a pressure feed motor for the piston which piston-cylinder combination is capable of feeding under a condition of airtightness between a succeeding device and the atmosphere. CONSTITUTION:A solid fuel raised with a stepped belt (not shown) is dropped into a hollowed piston 36 in a cylinder 41 and supported therein. At this time, the airtightness is maintained between a succeeding device and the atmosphere with a sealing section 49 of the hollowed piston 36. The stepped belt is stopped with a slide-drop signal of the solid fuel 8, a pressure feed motor (not shown) works to draw a rod 43 out, to retract a piston 36, and to cause the solid fuel 8 to slide down along a slope 38 to a hollow 37. At this time, seals 50, 51 keep airtightness. The pressure feed motor is then reversed to move the piston 36 and the hollowed piston 39 forward to forward the solid fuel. By repeating the procedure, the solid fuel is fed under airtight condition. The safety is improved because the contact between the fuel and air is shut off.

Abstract: PURPOSE:To perform stabilized food storage without influence by span gas or air entered in the calibration or filter exchange, by providing a control means to ignore the gas concentration signals from the gas monitor until a blower has been operated for a specified time to completion. CONSTITUTION:When a gas monitor 45 is to be calibrated or a filter exchanged, the switch 48 fitted on said monitor 45 is turned 'ON'. The signals from the switch 48 then enters the input terminal of a sequencer 49. And the sequencer 49 closes change-over valves 41, 42, 50, 51 to isolate a storehouse 1, combustion furnace 12 and absorption devices 22, 23 from a gas monitor 45 and chamber 46 during the switch 48 is 'ON'. When the calibration or filter exchange has been done, the switch 48 is turned 'OFF'. The sequencer 49 then opens the changeover valves 41, 42, 50, 51 to open the pipe to the storehouse and operate the blower 14 for a specified time, thus sufficiently replacing the span gas or air left in the gas monitor 45 and chamber 46 with the gas in the storehouse to effect unaffected state.

Abstract: PURPOSE:To restore the oxygen concentration to a preset level in a short time in case of the lowering of the oxygen concentration of a gas atmosphere in a preservation chamber for a perishable good, by using a preservation chamber receiving carbon dioxide gas generated from a combustion furnace and circulating the air from the chamber to the combustion furnace, and providing a change-over valve connectable to outer atmosphere between the combustion furnace and the preservation chamber. CONSTITUTION:Carbon dioxide gas generated in a combustion furnace 12 is introduced into a preservation chamber 1 for perishable goods through adsorption apparatuses 22, 23 and the air in the preservation chamber 1 is circulated to the combustion furnace 12. In the preservation apparatus having the above structure, change-over valves 28, 29, 33, 38 are provided at the upstream and downstream sides of the adsorption apparatuses 22, 23 and between the preservation chamber 1 and the combustion furnace 12. When the oxygen concentration in the preservation chamber is decreased below an arbitrarily preset level, the gas in the preservation chamber is discharged through the change-over valves 28, 38 to outer atmosphere and air is introduced through the change-over valves 35, 29 to return the oxygen concentration to the arbitrary preset level within a short time.

Abstract: PURPOSE:To obtain a perishable food storage apparatus cable of storing a perishable food in stable conditions, by constituting the apparatus so as to change O2 in a storage cabinet to CO2 by CO2 produced by combustion of fuel containing carbon and returning O2 concentration to set concentration. CONSTITUTION:A fuel containing carbon is fired in a combustion furnace 12 and simultaneously air fed for firing is circulated by an air blower 14. Excess CO2 is adsorbed with adsorbers 22 and 23 containing a charged adsorbing material and gas atmosphere of a change-over valve 49 and storage cabinet 1 are detected and each part is operated by means 50. In the above-mentioned case, clean gas is stored in the storage cabinet by changing over the valve using time control means 48. Further, even when O2 and CO2 concentrations in the storage cabinet 1 are deviated from prescribed concentration during storage, the perishable food can be stored in stable conditions, because the concentration can be readily returned to prescribed concentration.
