Patent number: 4530269Abstract: The present disclosure describes a latch assembly wherein structural members are coupled to each other by an electric match-type device interposed therebetween. The latter device generally comprises a body portion having electrical connections thereto and a rigid mass of combustible material firmly adhered to an extremity thereof. At least a pair of the structural members are individually coupled to the combustible material. Remote activation of the match by the passage of electric current therethrough results in the firing of the combustible material and the consequent opening of the latch through the elimination of the coupling force between the structural members.Type: GrantFiled: May 12, 1983Date of Patent: July 23, 1985Assignee: Burroughs Corp.Inventors: William G.

Patent number: 4424914Abstract: A completely separable seal for a container opening having a throat with a restriction therein including a casing, an explosive charge in the casing, a projectile tethered to the casing, the projectile including a thin completely separable peripheral diaphragm for closing the container throat having upper and lower surfaces, the charge mounted against the upper surface, means on the seal for engaging the throat restriction when the charge has been fired to subsequently limit downward thrust of the projectile into the container after separation of the diaphragm from the container throat to thus permit the projectile to reverse direction as the upward explosive forces overcome the downward explosive forces to thus propel the casing and tethered projectile from the container throat thus opening the container. The invention includes the complete closure for the container as well as the method of opening the rupturable sealed aperture.Type: GrantFiled: June 24, 1982Date of Patent: January 10, 1984Inventor: Milton F.

Patent number: 4248257Abstract: A gas actuated valve enabling high-speed actuation silently and rapidly os one or more blocked ports in a floodable container, thereby permitting the flooding of the otherwise closed container by ambient fluid. The valve includes a sleeve mounted for sliding movement about a base, the latter being attached to the interior of the container at each port. An electrically-initiated, gas-generating pyrotechnic bolt is threadedly connected between, and disposed in a cavity defined between the sleeve and the base. The bolt, before actuation, functions as a tensile member to withstand ambient pressure, thereby preventing the valve from opening prematurely. When actuated, the bolt fuses, separates, and releases hot gases into the cavity which expand and bear against the sleeve, causing the sleeve to move away from the port so that the container port opens completely thereby flooding the container.Type: GrantFiled: March 26, 1979Date of Patent: February 3, 1981Assignee: The United States of America as represented by the Secretary of the NavyInventor: Thomas K. C. Hardesty

Patent number: 4126184Abstract: An instantaneously actuatable, field-serviceable valve unit for pressurized fire suppression systems which allows extremely fast, essentially uninterrupted flow of extinguishant upon operation thereof and is constructed for permitting easy recharging and periodic servicing of the system in the field. The unit includes an elongated flow tube connected to a supply of extinguishant and having a pair of removably mounted rupture discs respectively located across the end of the tube and received in an aperture through the sidewall thereof, so that both discs experience the pressure of the extinguishant; a detonator is removably installed outside of the tube adjacent the sidewall-mounted disc for ready replacement thereof in the field, and is electrically actuatable in response to combustion conditions to explode and create a pressure sufficient to instantaneously burst the discs so that the pressurized extinguishant is released and allowed to flow uninterruptedly for quickly suppressing a fire.Type: GrantFiled: November 26, 1976Date of Patent: November 21, 1978Assignee: Fike Metal Products CorporationInventor: James O.

Patent number: 4077423Abstract: A high pressure gas container hermetically confining therein a high pressure gas for inflating instantaneously a safety air bag to protect occupants in a vehicle is provided with an improved discharge valve for blowing out the gas from the container. The discharge valve comprises a sealing disk disposed at a blocking cock portion, which disk has a thick center portion and thin peripheral portion so that the whole disk may be utterly ruptured upon explosion of a detonator disposed adjacent to the thicker portion of the sealing disk. Such complete destruction of the sealing disk will result in a formation of a large opening for blowing out the high pressure gas and hence allows a rapid inflation of the safety air bag due to increased flow rate of the jetted high pressure gas from the container.Type: GrantFiled: January 20, 1976Date of Patent: March 7, 1978Assignee: Nippon Soken, Inc.Inventors: Takao Kasagi, Satosi Kuwakado, Toshihiro Takei

Patent number: 4046156Abstract: Valve apparatus is disclosed for discharging pressurized fire extinguisher fluid from a container. The valve includes a diaphragm which is removably mounted within a two-part housing to facilitate field replacement. The diaphragm is formed with a semi-spherical shell which is mounted across a passage in the housing with a concave side of the shell facing the pressurized fluid. The shell is fabricated of a metal which is pre-stressed so that the diaphragm ruptures above a predetermined fluid pressure for relieving over-pressure from the container. An annular rim of the diaphragm includes a ductile metal ring which is compressed between the housing parts into fluid sealing relationship with an annular knife edge seal. A squib cartridge is mounted in the housing to rupture the diaphragm and permit the fluid to discharge through the passage. A screen is mounted in the passage to screen out fragments of the ruptured diaphragm from the flow stream.Type: GrantFiled: December 4, 1975Date of Patent: September 6, 1977Assignee: Systron-Donner CorporationInventor: Kenneth C.

Patent number: 3983892Abstract: An assembly for explosively shearing material to form openings in contain and to separate attached elements comprises an explosive material positioned within a groove in a backing support adjacent one side of the material to be severed. A shear element located on the other side of the material has its shearing edge axially aligned with the centerline of the groove and explosive material. Upon detonation, the explosive pressure forcibly displaces the material against the shearing edge, severing the material without fragmentation.Type: GrantFiled: December 6, 1974Date of Patent: October 5, 1976Assignee: The United States of America as represented by the Secretary of the NavyInventor: Thomas K.
