20100269379 | RIPPER BOOT INCLUDING A HIGH TENSILE TIP - The present invention relates to an improved ripper boot which includes a carrier section, and a ripper tooth section having a high tensile tip adapted to be press fit into a contact end thereof. In operation, the carrier section is placed over and conformed to fit over a ripper boot shank of a bulldozer, or one or more excavator loader bucket shanks. In using a press fit high tensile tip, less maintenance is required on the ripper boot during operation, which means that the machinery does not need to idle so often, saving considerable time and expense. The reason for this is that the tip is made of a high tensile metal such as tungsten which is less susceptible to wear and tear so it can be used for considerably longer periods before it becomes worn. Furthermore, hard and abrasive rock in front of the tungsten tip has been found to “explode” in its path resulting in the location of precious stones which would otherwise have been missed using conventional equipment. | 10-28-2010 |

20080229627 | Ripper Boot - The present invention relates to improvements to ripper boots of the type adapted to be mounted to a bulldozer tyne for use in cleaving through hard ground. The ripper boot embodied in the present invention has particular application in opal mining where sometimes extremely hard ground is to be penetrated and ripped. The ripper boot includes a replaceable ripping tooth which is secured within the boot by way of an interference fit so that during use, it does not rotate. The interference fit prevents particular matter from entering between the walls of the tooth and the associated socket. In further forms of the invention, the replaceable ripping tooth is angled upwardly with respect to the carrier so that the angle of attack of the ripping tooth is raised so that it is almost parallel with the ground. The ripper boot provides a number of benefits including improved cleaving effect, reduced chatter and drag, reduced wear and tear, and reduced load on associated machinery. | 09-25-2008 |

20140163940 | METHOD AND SYSTEM FOR MODELING RF EMISSIONS OCCURRING IN A RADIO FREQUENCY BAND - The method and system for modeling RF emissions occurring in a radio frequency band utilizes commercial off-the-shelf (COTS) hardware to perform the steps of converting legacy PDW databases to RF signal I and Q format and storing the I and Q data in a digital I and Q data signal library. Alternatively, real-time RF signals are recorded in I and Q format and routed to the library. Moreover, a synthesizer is provided to form I and Q data and forward the data to the library. I and Q library data is time-tagged. An RF editor includes editing tools to modify the I and Q library accordingly, as required. A channelizer extracts channel information from the I and Q data and sends that channelized data to at least one to vector signal generator. A combiner is used to combine outputs of multiple vector signal generators connected to the channelizer. | 06-12-2014 |
