  • Patent number: 8794157
    Abstract: Automatic machine for leveling and alignment of ballastless railway, prior to concreting, having a structure (1) that moves along the track, provided with fastening elements to, once located in the track section to be positioned, firmly grab both rails (10) keeping the track in suspension while it performs millimetric movements of displacement until placing it in the desired final position, both in plant and height of the rails and cant; said machine has a measuring system, which includes tilt sensors (11) and a total station (12) of GPS or topographic type, that allow to identify the actual position of the track, in real-time. It also has a control system that includes process software of the position data acquired by the measuring devices (11-12), from which it determines the required movements to be carried out to achieve the desired final position of the track.

  • Patent number: 7089867
    Abstract: A device for use in television and motion picture industries lifts and re-positions a track on which camera dolly or crane is located. The device includes a first bar member of a substantially elongated shape comprising a hinge, a first caster wheel assembly, and a first track hook which is positioned at one end of the first bar member. A second bar member of a substantially elongated shape shorter than the first bar member is pivotably attached to the first bar member via the hinge such that when in a closed position the first and second bar members form a substantially straight line. The second bar member further comprises a second caster wheel assembly and a second track hook which is positioned at one end of the second bar member, this one end of the second bar member being at an opposite location than the other end of the first bar member along the substantially straight line.

  • Patent number: 6208994
    Abstract: A system and method for adding support for new contained classes to a container class that does not require the container class to be recompiled. Also disclosed is a system and method for building container classes that does not require a programmer to explicitly code methods related to the contained classes. A set of classes, called Supporters, provides support for contained classes. Related Supporters can be packaged as a library that can be shipped with programming environments, updated APIs or device drivers. A SupporterAffinity manages Supporters for use by a particular contained class. A SupporterAffinity method (“getSupporter”) can be invoked to add a Supporter for a new contained class to the SupporterAffinity, allowing an instance of the container class to use that Supporter's methods on instances of the new contained class. Because support for the new container class is provided via the SupporterAffinity and the new Supporter, there is no need to recode the container class.

  • Patent number: 5400550
    Abstract: An improved turntable is provided for use in a building, such as in a residential or office environment, wherein the turntable is constructed from modular components for facilitated installation within a relatively low profile space. The turntable comprises a skeletal frame including an outer rim in combination with a plurality of radially extending support beams, wherein the assembled frame defines a plurality of generally pie-shaped openings for nested reception of a corresponding plurality of lightweight modular panel units. Wheels are mounted to the outer rim in adjacent pairs on opposite sides of each radial support beam for shared distribution of loads applied to the turntable during use. A traction drive surface is formed on the periphery of the outer rim in a position engaged by a drive roller of a low profile drive unit.
