Title: Method and apparatus for suppressing explosions and fires
Inventor: O'CONNELL MICHAEL O
IPC: A62C3/04
Filed: 1988-03-25
Granted: 1993-05-18
Abstract: ABSTRACT            Apparatus for suppressing explosions comprises a reservoir means containing hot pressurised water which is heated by a heating means.  On explosion conditions occurring in an enclosure a high speed differential pressure diaphragm is fractured to release a charge of hot pressurised water into the enclosure.   When the water enters the enclosure portion it is converted into water droplets to suppress the flame front of a deflagration and portion of the water flashes  off  as  flash  steam to  reduce  the  oxygen concentration and suppress the explosion.  A differential pressure  diaphragm  40  comprises  a  pair  of  bursting diaphragms having a space therebetween which is maintained at a balance pressure.    When explosion conditions occur the balance is disturbed and the diaphragms burst under the higher pressure.

Title: Arc device with adjustable cathode
Inventor: WLODARCZYK JANUSZ
IPC: B23K10/00
Filed: 1988-05-03
Granted: 1992-06-02
Abstract: ABSTRACT            An arc plasma generating system includes components for adjusting spacing between the cathode and the anode.  A piston affixed to the cathode is slidingly positioned in a cylinder partitioning therein a first chamber and a second chamber.  The first chamber is receptive of discharged cooling fluid at reduced pressure. A first valve selectively infuses pressurized control fluid into the second chamber such as to move the piston against the reduced pressure and thereby move the cathode axially in a first direction.  A second valve selectively discharges the control fluid from the second chamber such that the reduced pressure in the first chamber moves the piston opposite the first direction.          Telescoping tubing affixed between the piston and the end wall of the cylinder is located within the cylinder and conveys cooling fluid to the cathode.  A flexible electrical cable connected between the cathode and a source of arc current is located within the cylinder member such as to be cooled by fluid therein.

Abstract: TITLE: SOD HARVESTER WITH CURVED CONVEYOR A sod harvester in which sod is cut, conveyed upwardly, and then travels downwardly over a floppy conveyor and falls into a roll forming enclosure formed by a bottom conveyor and a vertical conveyor. The floppy conveyor swings downwardly at the start of roll forming, to reduce the free fall of the sod, and swings upwardly as the roll grows. When the roll is formed, the bottom conveyor is unlatched and tilts downwardly to discharge the roll, at the same time pulling into cocked position a core tube injector arm. When the roll discharges, the bottom conveyor snaps upwardly, releasing the core tube injector arm which injects a fresh core tube into the roll forming enclosure. The sod is rolled with its grass side outwardly to facilitate laying and to protect the grass roots. A tray on a cart at the end of the harvester receives the discharged roll and can convey it to either side of the cart. When the tray reaches either side of the cart, a cam tilts the tray to discharge the roll onto the ground clear of the next pass of the harvester.
