20090065599 | RAILWAY RAIL FASTENING CLIP - A substantially M-shaped rail clip is disclosed in which the clip is substantially flat when in its non-operative configuration, and, when the clip is in an operative configuration, the toe of the clip lies substantially in a second plane and the legs of the clip lie substantially in a third plane, the second and third planes being non-parallel to one another. | 03-12-2009 |
20090218410 | ANCHORING DEVICES FOR RAIL FASTENING CLIPS - A shoulder for use in retaining a railway rail fastening clip, comprising two interconnected spaced-apart walls, between which a portion of the clip to be retained is held when the shoulder is in use, and clip-engaging means, supported by the walls, for engaging a portion of the clip to be retained, does not have any feature or surface which engages the surface of that clip portion which faces downwardly when the clip is in use. Alternatively, or in addition, none of the contact regions, at which the device engages the rail clip, can be seen when the anchoring device is viewed from above when in its operative orientation and all of the contact regions can be seen when the anchoring device is viewed from below when in the operative orientation. Alternatively, or in addition, all the contact regions lie substantially at the same horizontal distance from the edge of the rail foot when measured perpendicularly to the axis of the rail and in the plane of the rail foot. | 09-03-2009 |
20090261177 | RAILWAY RAIL PAD - A rail pad is disclosed having two upstanding portions, integrally formed with the rail seat portion along opposite edges thereof, so as to extend along only a central part of the edge. Preferably, the upstanding portions are attached to the rail seat portion in such a manner as to be readily detachable therefrom. | 10-22-2009 |

20150107491 | CEMENTITIOUS BINDERS, ACTIVATORS AND METHODS FOR MAKING CONCRETE - A cementitious binder comprises at least 90% by weight of a hydraulically-active material comprising ground granulated blast furnace slag (GGBS) and/or pulverised fuel ash (PFA), and at least 0.1% by weight of CaO in an activator composition for the hydraulically-active material. The cementitious binder does not comprise any Portland cement and is, therefore, more environmentally friendly. The binder further comprises a superplasticiser such as a polycarboxylate ether (PCE). A concrete, mortar, grout, screed or render may be formed from a mixture of the cementitious binder, aggregate particles, water and superplasticiser. | 04-23-2015 |

20150121785 | IMPALEMENT PREVENTION APPARATUS FOR EXTENDING OVERTOP OF AND AROUND THE EXPOSED ENDS OF A PLURALITY OF SPACED-APART REINFORCING BARS - There is provided an impalement prevention apparatus for use with a plurality of spaced-part bars. The apparatus includes an elongate top portion shaped to extend overtop of exposed ends of the bars. The apparatus includes a pair of elongate spaced-apart side portions connecting to the top portion and extending downwards therefrom. The apparatus includes a pair of spaced-apart end portions each connecting to and extending between the side portions. The top portion, the side portions and the end portions form an enclosure extendable around the exposed ends of the bars. | 05-07-2015 |

20090296184 | Illumination Obscurement Device - An illumination obscurement device for controlling the obscurement of illumination from a light source which is optimized for use with a rectangular, arrayed, selective reflection device. In a preferred embodiment, a rotatable shutter with three positions is placed between a light source and a DMD. The first position of the shutter is a mask, preferably an out of focus circle. This out of focus circle creates a circular mask and changes any unwanted dim reflection to a circular shape. The second position of the shutter is completely open, allowing substantially all the light to pass. The third position of the shutter is completely closed, blocking substantially all the light from passing. By controlling the penumbra illumination surrounding the desired illumination, DMDs can be used in illumination devices without creating undesirable rectangular penumbras. | 12-03-2009 |

20100287487 | Virtual Reality Interface for Show Control - A system for designing light and sound systems for use in stage productions. Virtual reality interfaces facilitate the selection and location of lighting and sound displays by providing a real-time simulation of the devices and the display produced thereby. The system also calculates parameters with respect to structural elements used for mounting the lighting and sound equipment. In addition, the virtual reality interface permits the simulation of the packing of the lighting and sound equipment and the automatic calculation of parameters relating to packing space, package weight, preferred location, and order of packing. | 11-11-2010 |

20120008325 | Programmable Light Beam Shape Altering Device Using Separate Programmable Micromirrors for Each Primary Color - Three-digital micromirror devices (“DMD”) are used to alter the shape of light that is projected onto a stage. The DMDs each receive a primary color and selectively reflects some light of that color, thereby shaping the light that is projected onto the stage. The control for the alteration is controlled by an image. That image can be processed, thereby carrying out image processing effects on the shape of the light that is displayed. One preferred application follow the shape of the performer and illuminates the performer using a shape that adaptively follows the performer's image. This results in a shadowless follow spot. | 01-12-2012 |
