EXPANSIBLE BREAKING-DOWN DEVICES | 3 |
| 20150102652 | CARTRIDGE FOR TUNNEL BLASTING - A cartridge for tunnel blasting is provided a cartridge for tunnel blasting, which easily breaks a rock, by inserting a cartridge containing water into a bore hole formed in a rock by using a boring device, and injecting liquid nitrogen into the inserted cartridge, so as to induce cracks of the rock by using the characteristic of the water that expands when it is frozen. | 04-16-2015 |
| 20090218877 | DEVICE FOR BREAKING SOLID MATERIAL AND METHOD OF MANUFACTURING A HOSE ELEMENT FOR SUCH A DEVICE - A device for breaking solid material comprises an expansible hose element which is insertable into a hole in the solid material and has an externally substantially geometrically regular cross-section. At least at one of its ends, the hose element comprises a coupling. The device further comprises at least one expansion portion with an expansion chamber. The hose element further comprises an expansion limiter which has a varying radial distance from the outside of the hose element along the circumferential direction of the hose element. | 09-03-2009 |
| 20120091783 | EXPANSION DEVICE FOR BREAKING SOLID MATERIAL, USE OF THE DEVICE AND METHOD FOR PRODUCING IT - An expansion device for breaking solid materials, including at least one hose element having an inner expansion chamber with a non-circular cross section before pressurization or having an inner pressuring means and/or a reinforcement arranged on the outside of the inner expansion chamber which has a non-circular cross section before pressurization. The inner pressuring means is arranged around the inner expansion chamber and the reinforcement is arranged around the inner pressuring means. Optionally an outer layer is arranged around the reinforcement, having at least one “directional-breaking-force amending” material portion which is arranged outside the reinforcement. The at least one hose element has a coupling connection on a first end of the hose element, and optionally a second coupling connection on a second end of the hose element. | 04-19-2012 |

ICE-WORKING DEVICES | 2 |
| 20140145494 | Ice Breaking / Rubblizing Machine - An ice breaking machine has a frame adapted to be mounted on a vehicle, and two subframes rotatably connected thereunder. The subframes in turn carry axles on which are mounted a plurality of wheel assemblies each composed of a wheel with six point mounts carrying six standard heavy equipment teeth. The wheels are keyed to the axle, with a mathematical relationship between the angles of the keyways of adjoining wheels so that the teeth of each wheel are slightly out of line with the teeth of the wheels on either side. | 05-29-2014 |
| 20150308063 | ICE PULVERIZING KNIFE AND ICE PULVERIZING DEVICE COMPRISING AN ICE PULVERIZING KNIFE - The present specification relates to an ice pulverizing knife for pulverizing ice from a ground surface, and to an ice pulverizing device equipped therewith. The ice pulverizing knife comprises a frame and a plurality of blades. The frame has a substantially circular base and comprises a top, a base and at least one opening. The top has a socket adapted for mechanically coupling the frame with a vertical drive shaft. Rotation of the vertical drive shaft results in rotation of the frame. The base engages with the ice on the ground surface. The at least one opening is positioned between the top and the base. The plurality of blades is secured to the frame. Each blade radially projects from the frame and engages with the ice on the ground surface for cutting the ice. Ice cut by the blade and accumulated inside the frame is expelled from the frame through the at least one opening. | 10-29-2015 |

MISCELLANEOUS | 1 |
| 20140361600 | Cold Planer Anti-Slabbing Mechanism - A cold planer includes a frame and a cutting mechanism having a rotatable cutter configured to cut material of a substrate. An anti-slabbing mechanism is coupled to the frame and includes an upwardly oriented base plate, and a plurality of skids. The skids are arranged in a first subset and a second subset positioned upon opposite outboard sides of a forwardly projecting plow, and downwardly depend from a base plate of the anti-slabbing mechanism, for applying a slabbing opposition force to uncut material of the substrate. | 12-11-2014 |
