    Abstract: An energy absorber comprises an intermediate portion interconnecting a first end and a second end. The intermediate portion and the first and second ends are on the same plane. The intermediate portion includes curved portions configured and arranged to deform and begin to straighten when subjected to a pre-determined load to absorb energy from the pre-determined load. Should a user fall, the energy absorber will deform (begin to straighten) to absorb energy from the fall. Optional pins prevent material from getting caught in the energy absorber, assist in stiffening the energy absorber, and assist in pre-stressing the energy absorber so that it will not open up when subjected to a load less than the pre-determined load. Optional tabs and slots or protrusions and notches prevent material from getting caught in the energy absorber.

  • Patent number: 7910856
    Abstract: A processing table 3 holding a workpiece 2 is accommodated in a chamber 4 with a gas-tight condition kept, and a liquid column W is jetted to an upper surface of this chamber 4, and a processing head 9 that guides laser beam L to the liquid column W is secured to the upper surface of this chamber 4. An oil-sealed rotary pump 11 and a diffusion pump 12 provided in parallel are connected to the chamber 4, and the diffusion pump 12 is actuated after the actuation of the oil-sealed rotary pump 11, bringing the inside of the chamber 4 into a vacuum state. No gas currents are generated around the liquid column W jetted from the processing head 9, making it possible to prevent turbulence of the liquid column W due to turbulence of the gas currents and enabling a liquid column having a small diameter to be jetted in a stable state.

  • Publication number: 20100324868
    Abstract: Core samples may be easily, quickly, and safely split using a fluid cutter, such as a water jet. Cutting may take place upon exit of the sample from the drill tube, or core samples may be placed in core carriers for cutting. Core samples may also be stored and transported in the core carriers. Assessment of core samples is facilitated by scanning the core samples, with the results stored to produce a virtual core sample. Virtual core samples may be displayed on a computing device, including a core sample display device which simulates the appearance of a section of an actual core.

  • Publication number: 20100263323
    Abstract: A decorative tile or set of tiles is provided for use in swimming pools, bathrooms, kitchens and the like. Tiles are manufactured to have a glazed front surface of a first color, and one or more openings in said front surface in a pattern. Decorative grouts are used to fill the openings in the glazed tiles to produce the desired decorative effect. In use, the tiles are held in place by a conventional bedding grout, and finished with a finishing grout. The openings are preferably holes through the tile, having openings at front and back. In a preferred embodiment, some or all of the decorative grouting that is used to fill the openings is a phosphorescent grout that accumulates solar or other light energy, and glows in the dark.

  • Patent number: 7806750
    Abstract: An apparatus and method for cutting a material using a water jet. A central shaft is mounted so as to extend outward from a material to be cut. A support member is mounted on the central shaft so as to extend transversely therefrom. At least one water jet cutting head is mounted on the support member so as to be translatable therealong. In addition, the at least one water jet cutting head is mounted so as to be rotatable about the central shaft. By controlling the translatory and rotational motion of the at least one water jet cutting head (for example, using computer numerical control or other computer control), a desired cut pattern can be followed with respect to the material being cut.

  • Publication number: 20100243332
    Abstract: A soil auger for creating smooth-walled cylindrical holes in the earth is provided for use with a drill. The auger has a central rotational axis with a tubular body that is open at a bottom cutting end, and enclosed at a top end by a cap assembly. The cap assembly has a top wall and a bottom wall. The top and bottom walls have apertures aligned with the central rotational axis for receiving a shaft in alignment therewith, and for attachment to a drill. The distance between the top wall and bottom wall compared to the overall length of the assembled auger determines the minimum height of the cap assembly to minimize the rotational imbalance of the auger during use for a given body length. A method of manufacturing the auger is provided using precision cutting tools to create apertures in the body and to maintain concentricity of the auger components.

  • Publication number: 20100180738
    Abstract: A liquid cutting device employing pressurized working liquid which includes a nozzle assembly. The assembly includes a plurality of liquid jet nozzles, each nozzle of which has a nozzle axis. The plurality of nozzles are arranged so that their nozzle axes intersect at an intersection point located at a predetermined distance downstream from the nozzles. The device also includes an apparatus for delivering the pressurized working liquid to the nozzles. Each of the nozzles is configured to selectably emit a liquid jet operative to cut through a target material. The liquid jets emitted from the nozzles interfere and disperse each other when meeting at the intersection point and the liquid jets are atomized. The device includes a spacer element adjustably mounted onto the nozzle assembly, which increases or decreases the cutting depth of the device. A method for employing the liquid cutting device is also discussed.
