Abstract: In an aspect of the invention a ripping mechanism for a vehicle is provided which includes a support frame, a ripping member and an impact mechanism, such as a vibrator, which is configured to reciprocate the ripping member forwardly and rearwardly about a transverse pivot axis. The ripping member is mounted within a sleeve that pivots with the ripping member about the pivot axis, while at the same time selectively permitting movement of the ripping member along the sleeve. The ripping member may thereby be raised or lowered relative to the sleeve in order to adjust the depth of the engagement head relative to the support frame.

Abstract: An impacting apparatus and a vehicle having such an apparatus, the apparatus having a mounting portion securable to the vehicle, a tool support portion pivotally connected adjacent a first edge of the tool support portion to the mounting portion via a pivotal connection and flexibly connected at a second edge of the tool support portion to the mounting portion via a flexible connection remote from the pivotal connection, vibration means mounted between the mounting portion and the tool support portion for reciprocating the tool support portion relative the mounting portion via the flexible connection and a tool extending from the tool support portion. The flexible connection comprises resilient elements held by a fastening means between end plates. The fastening means has tightening means for adjusting the flexible connection to a predetermined compression setting of the resilient elements.

Abstract: A plow trenching apparatus for a vehicle having a raisable boom and a trenching plow pivotally mounted at a distal end of the boom in a plow holder, to extend rearwardly and downwardly therefrom. The plow has an upper portion and a lower portion, with a forwardly protruding toe portion, and a forward facing cutting portion. The plow is pivotable in the holder about a pivot axis located behind the holder and behind the plow, as seen in the travel direction of the plow during operation. A pivoting motion is imparted to the plow by a vibrator arranged at the upper portion. The vibrator is arranged to impart vibrations generally in a vertical plane, so that the lower portion is pivoted generally back and forth in the travel direction. The vibrator can be located behind or in front of the upper portion.

Abstract: A plow trenching apparatus for a vehicle having a raisable boom structure, for example a skid steer vehicle. The apparatus comprises a tool attached to a tool mounting plate of the boom structure. The tool has an arm mounting plate, attachable to the tool mounting plate, a J-shaped curved arm having an arm mount arranged at one end and a plow holder mount arranged at the other end, a plow holder attachable to the plow holder mount, the plow holder mount permitting the plow holder to pivot horizontally, a plow attachable to the plow holder, and a hydraulic cylinder. The arm mount is attachable to the arm mounting plate via an arm pivot attachment. The curved arm is horizontally pivotable at the arm mount by the hydraulic cylinder. The hydraulic cylinder is extendable and retractable and attached to the arm mounting plate via a hydraulic cylinder attachment and attached to the curved arm via an arm pivoting attachment arranged on the curved arm.

Abstract: An isolation mount having a first mounting surface arranged on a vehicle. The first surface has substantially vertical first mounting lugs arranged at a lower end of the first surface, and a first fastening device for holding at least one pair of resilient device. The resilient devices comprise first resilient portions and second resilient portions. The first fastening device is preferably arranged at a top end of the first surface. The isolation mount further has a pivoting device, which has a first side facing the first surface, a second side facing away from the first surface and substantially vertical second mounting lugs arranged at a lower end of the first side of the pivoting device. The second mounting lugs are attachable to the first mounting lugs via pins to form a first hinge, about which the pivoting device is pivotable. The pivoting device further has resilient device holding device arranged at a top end of the pivoting device.

Abstract: Conventional cable-laying apparatus has been adapted for the removal of cable. A trenching plow blade is towed behind a bulldozer or the like. Mounted above the area of the blade is a powered cable-pulling assembly. Once an initial length of cable is excavated and routed to the cable pulling assembly, the equipment is advanced along the line of the cable to dig the trench, preferably just a small distance above the cable, such as about a foot, and the cable pulling assembly is driven to pull the cable from the ground behind the advanced blade. The cable may be routed to lie on the ground behind the advancing apparatus, or alternatively may be routed forward over the cab of the bulldozer onto a powered rewind reel. The cable pulling assembly includes a pulling wheel rotatably mounted to the blade support assembly, rotated by a hydraulic motor through a reduction gearbox. A series of rollers are mounted between two roller support arms.

Abstract: A trenching plow blade having replaceable wear components is disclosed. A preferably octagonal rod with regularly spaced transverse holes drilled therethrough is welded to the leading edge of the blade. Replaceable leading edge cover pieces each have a channel therein with a shape complementary to the front face of the rod, and transverse holes adapted to align with the transverse holes in the rod. Pins are positioned through the holes to hold the covers in place. Preferably, straight and curved sections of the covers are provided as required. For the toe of the blade, a toe cover is preferably provided. The rod and covers may be supplied as a kit, which is readily installed since the only operation required is welding.

Abstract: The invention provides automated adjustment of the height of a trenching blade. There is a blade holder having a generally vertical channel defined therein, and support means for carrying the blade holder behind a vehicle at a height above the ground. A trenching blade for dragging through the ground behind the vehicle has a shank portion extending upwardly therefrom into the channel and slidably engaging in the channel for vertical movement therewithin, whereby the depth of the blade may be varied. At least one hydraulic cylinder is connected between the blade holder and the blade shank for varying the position of the blade shank within the blade holder and thereby varying the depth of the blade. In the preferred embodiment, the support means is at the end of a boom which is pivotally connected to the vehicle for pivotal movement about a generally vertical axis, and the blade holder is pivotally mounted to the support means, for pivotal movement about a generally vertical axis.

Abstract: The method of this invention is particularly, although not exclusively, adapted for effecting accelerated oxidation reactions in a downhole or deep well wet oxidation apparatus, including the processing of aqueous organic waste, such as municipal sludge. It includes injecting a multiple-phase composition which contains an oxygen or an oxygen-rich gas which is fully saturated with water vapor and which also contains water in the liquid phase into a wet oxidation reaction apparatus which contains an aqueous stream of combustible waste, preferably at the temperature and pressure of the waste stream at the point of injection. This reduces the likelihood of hazardous spontaneous combustion which may otherwise occur if dry spots are allowed to form in the reaction apparatus. The volume of water in the composition should be equal to at least twice the volume of water necessary to saturate the gas with water vapor to maintain at least 50 percent of the water in the liquid phase.

Abstract: A process for reducing calcium, magnesium and aluminum salt scale build-up in continuous flow or plug flow tube reactors in which a fluid waste undergoes a chemical reaction under heat and pressure to form more environmentally desirable compounds. The process includes the injection of a precipitating reagent into the influent path of a fluid waste stream in a tube reactor to preferentially precipitate calcium, magnesium and aluminum ions which are then carried through and out of the reaction apparatus in a non-scale forming suspension.
