Patent number: 5215721Abstract: A gas generating device for supplying gas in an air bag or the like is provided with a gas generating composition, which is burned by an ignitor to generate gas, and a primary filter for filtering the burnt gas. The gas generating composition and the filter are placed in a combustion chamber having a primary gas exhausting port. The primary filter is chemically inactive with respect to the burnt procedure of the gas generating composition. The filter has a metal screen whose melting point is equal to or higher than the burning temperature of the gas generating composition. A cooling chamber is provided which communicates via the primary gas exhausting port with the combustion chamber. In the cooling chamber is disposed a secondary filter which cools gas coming out of the combustion chamber and filters the burning residue in the gas. A secondary gas exhausting port is formed in the cooling chamber to discharge the gas filtered by the secondary filter.Type: GrantFiled: September 6, 1991Date of Patent: June 1, 1993Assignee: Nippon Oil and Fats Co., Ltd.Inventors: Youji Tasaki, Nobuyoshi Sasaki

Patent number: 5213773Abstract: A liquid treatment system receives untreated liquid from a pressurized source and outputs treated liquid on demand. An ozone containing gas from a generator is combined with untreated liquid to accomplish the desired treatment before the liquid is output; and the necessary operations include pumping, venting, a demand event switch, and a control system to accomplish the necessary functions. A valved liquid passageway conducts untreated liquid to a contact region, accumulated gas is vented from the system. A demand event can be manual operation of an output switch or manual operation of an outflow valve that causes a liquid level change within the system. Treated liquid outflow can occur by gravity, as a passive outflow in response to opening an inflow valve, and as an active outflow driven by a pump.Type: GrantFiled: March 10, 1992Date of Patent: May 25, 1993Inventor: William A.

Patent number: 5145647Abstract: The pressurization period of an autoclave is controlled by an oscillator which provides an output to the autoclave control unit. The control unit has a microprocessor with its own clock. The number of times that a portion of the program is carried out by the microprocessor during the pressurization period of the autoclave, is counted into a register to decrease a separately established count in the register. This separately established count is representative of the correct operating time of the pressurization period. If, at the end of the pressurization period, the count in the register exceeds zero by more than an allowable error, a fault indication is produced on a display and the autoclave door is maintained locked so as to prevent access to articles in the autoclave.Type: GrantFiled: October 22, 1990Date of Patent: September 8, 1992Assignee: Smiths Industries Public Limited Co.Inventor: Richard Murray-Shelley
