| 181 | Suppressing explosions and installation | US744982 | 1996-11-07 | US5728967A | 1998-03-17 | John H. Parkes |
| A method of limiting an environmental disturbance caused by exploding explosive material, comprising spraying liquid to generate a liquid dispersion about the explosive material to be exploded and detonating the explosive material so that it explodes in the dispersion. The invention also relates to an installation for limiting the environmental disturbance of an explosion. | ||||||
| 182 | Collapsible duct coupling | US124710 | 1993-09-24 | US5449320A | 1995-09-12 | Lawrence E. Shea |
| Fiberglass reinforced plastic duct exhaust systems including sections of the duct system joined together by collapsible collar plastic joints having low melting points which collapse or drop-out of the system when exposed to high temperatures. | ||||||
| 183 | Flame arrestor | US147749 | 1988-01-25 | US4964882A | 1990-10-23 | Alan R. Gaul |
| The invention teaches a method of spacing the elements of a flame arrestor and securing that spacing in a simple and economical manner. A shim is used to space the elements, the elements are welded together and the shim is removed. This leaves a controlled flow path between the elements, but the spacing is such to prevent the propagation of a flame through the arrestor. | ||||||
| 184 | Flame arrester having detonation-attenuating means | US300034 | 1989-01-23 | US4909730A | 1990-03-20 | Nicholas Roussakis; Kenneth O. Lapp |
| A flame arrester for a pipe line is provided comprising a detonation attenuator mounted within the arrester chamber between the quenching element and the backflash flame inlet. The attenuator is generally cup-shaped, aligned with the inlet, of greater diameter than the inlet but of lesser diameter than the arrester chamber, and is positioned close to the inlet so as to circumscribe it. The major portion of the high pressure central portion of a detonation wave generated by a backflash is received by the cup and reflected back into the pipe. Some of the detonation wave passes around the cup and impinges on the arrester element--however it has been delayed sufficiently to ensure complete quenching of the flame front in the element. | ||||||
| 185 | Blast wave choke | US926509 | 1986-11-03 | US4751874A | 1988-06-21 | Edward A. Quarterman |
| A blast wave choke to be disposed at the above ground entrances of a ventilation system for a underground personnel shelter wherein a plurality of annular choke elements of progressively smaller inside diameter are aligned along a common axis and spaced one from the other by annular interposed spacer elements wherein each spacer element has an inside diameter that is greater than the adjacent choke elements wherein a blast wave entering the ventilation system will encounter a series of rings and set up an interference pattern which will dissipate the energy of the blast wave before it can enter the underground shelter and cause injury to persons or damage to property therein. | ||||||
| 186 | Flame arrestor | US233769 | 1981-02-12 | US4374649A | 1983-02-22 | Subbarao N. Rao |
| A flame arrestor is disclosed which includes a conduit extending along inside of a drum arranged to contain a quantity of non-combustible liquid. This conduit is equipped with bubbler nozzles that discharge a combustible gas into the liquid in the form of separate, discrete bubbles. The gas is drawn from the drum through outlets above the liquid level and deflectors are positioned to deflect and distribute a flame front entering the drum through any of the nozzles. | ||||||
| 187 | Gas flame torch system with flash arresters | US204336 | 1980-11-05 | US4361420A | 1982-11-30 | Theodore F. Bell |
| For use in a welding system which uses combustible gases and the like, a flash arrester comprising a main body having an opening therethrough and including a frusto-conical seat, and a ball cage body positioned in the main body and having an axial opening therein. The ball cage body has a frusto-conical seat complementary to the first-mentioned seat of the main body. The other end of the ball cage body has axially extending slots to provide spaced axially extending fingers. The fingers have frusto-conical surfaces. A ball seat member is provided on the other end of the main body and has a frusto-conical ball seat. A ceramic ball is provided between the fingers and is freely movable between the second valve seat and the ball seat. | ||||||
| 188 | Safety device | US3711259D | 1970-03-10 | US3711259A | 1973-01-16 | GURNEY W |
| A FLAME ARRESTER WHICH COMPRISES CLOSURE MEANS FOR ALLOWING GAS TO PASS THERETHROUGH WHILE PREVENTING PASSAGE OF A FLAME AND RETAINING MEANS FOR RETAINING THE CLOSURE MEANS IN POSITION IN OR ADJACENT AN APERTURE OR PASSAGE AND IN WHICH THE CLOSURE MEANS COMPRISES A POROUS METAL AND/OR CERAMIC MATERIAL IN THE FORM OF A THREE-DIMENSIONAL NETWORK ARRANGED TO DEFINE A PLURALITY OF CELLULAR SPACED WHICH INTERCOMMUNICATE WITH ONE ANOTHER AND THE RETAINING MEANS COMPRISES A COMPRESSED PORTION OF THE THREE-DIMENSIONAL NETWORK OF THE CLOSURE MEANS. PREFERABLY THE CLOSURE MEMBER IS A RETICULATED POLYURETHANE FOAM WHICH HAS BEEN ELECTROPLATED WITH THE NICKEL OR IORN.

| 189 | Flow system having electrostatic charge reducer | US3616815D | 1969-06-17 | US3616815A | 1971-11-02 | ERICKSON CHARLES D; CIOTTI GEORGE A |
| A FLOW SYSTEM FOR PETROLEUM PRODUCTS AND THE LIKE. AN UNSHROUDED STATIC CHARGE REDUCER TUBE IS CONNECTED IN THE STORAGE MEANS OF THE FLOW SYSTEM FOR ELIMINATING ELECTROSTATIC MEANS OF THE FLOW LIQUID FLOW. THE REDUCER IS FORMED OF A SUITABLE PLASTIC AND A PLURALITY OF PINS PROJECT INWARDLY INTO THE INTERNAL FLOW PASSAGEWAY. A CONDUCTIVE MEMBER CONNECTS THE PINS TO THE STORAGE MEANS OR SOME OTHER ELEMENT WHICH DEFINES A GROUND CONNECTION.
