20080277557 | Anchor assembly - An anchor assembly includes a base to which at least one connector and three legs are operatively connected. The connector provides an anchorage point for connection to a lifeline. The legs are secured to a support structure. The legs are reinforced proximate the base and when a force is exerted on the at least one connector by the lifeline, the legs bend proximate the support structure thus placing a shear load on the legs proximate the support structure. | 11-13-2008 |
20090152045 | MOBILE MOUNT FOR ATTACHMENT OF A FALL ARREST SYSTEM - A mobile mount for attachment of a fall arrest system. The mobile mount includes a mobile base, a support, at least one base, at least one arm and at least one anchor. The mobile base has a first side and a second side. The support extends upward from proximate the first side of the mobile base. The support also has a first end coupled to the mobile base and a second end. The at least one brace is coupled between the support and the mobile base to maintain the support in an upward position in relation to the mobile base. The at least one brace is slideably coupled to the mobile base. The at least one arm assembly is coupled to the second end of the support and extends from the support so as to be cantilevered over the mobile base. The at least one anchor is configured to be attached to the fall arrest system. Moreover, the at least one anchor is coupled to the at least one arm assembly. | 06-18-2009 |
20100236799 | COMPRESSED AIR FOAM SYSTEM FOR FIRE RETARDANCE - An apparatus for protecting a structure from fire includes a foam generation system by mixing compressed air, water from a pump and a foaming agent from a metered supply together with a series of motor driven nozzles and a control device which is programable to provide a program of operation to control the motors of the nozzles so as to pre-determine a pattern by which a building is repeatedly covered by a layer of the foam. The control device can include plurality of different programs of operation of the nozzles with different times for different fire conditions. A remote control allows the apparatus to be activated from a safe remote location. An arrangement is provided to automatically start the foam generation system including an internal combustion engine. | 09-23-2010 |
20110002731 | LATCHING DEVICE FOR INSERTION INTO A TUBE FOR LATCHING MOVEMENT OF THE TUBE RELATIVE TO AN EXTERNAL ELEMENT - A latching device for insertion into a tube provides two large flat buttons one on each side to lock the tube relative to an outer tube or to two parallel plates. A tubular housing with open ends slides into the tube between the side walls of the tube with the ends of the housing substantially butting inside surfaces of the side walls. The buttons are mounted on respective slide members mounted in the housing spring biased apart so that the buttons can be depressed. One or two set screws acting as stop members can be inserted after the housing is moved to the required location in the tube to prevent depression of the buttons to a position inward of the inner surface of the tube so that the housing is held in place. | 01-06-2011 |
20110073408 | LIFELINE SUPPORT RAIL - A life line support for the traveler of a safety harness includes an elongate flexible tensioned cable and a square tube loosely surrounding the cable defining an outside surface for receiving the traveler for movement along the tube. The traveler includes rollers and is formed in two parts which can open to engage around the tube from one side and held closed by the attachment of the life line. The tube is tensioned between wall mountings and the cable is tensioned relative to the wall mountings by additional springs pulling on the cable separately from the tube. The cable thus provides the support strength while the tube provides the rolling surface. | 03-31-2011 |
20120193165 | Apparatus for Receiving Shock Loading - A fall restraint system includes a cable for attachment to a fall restraint harness assembly of a worker. The cable can be attached to a boom arm cantilevered on a mast carried from the ground or can be stretched between two points on opposed walls. A shock absorber is provided for absorbing at least part of the shock forces so as to reduce the loading applied to the support system. This comprises an elongate member with a movable member or sleeve mounted on it for longitudinal movement. The movement is resisted by a friction brake or a compressible material contained within a tube so that the sleeve moves along the tube in response to loads exceeding the normal load to reduce the loading on the cable while compressing the material in the tube. | 08-02-2012 |

20130313396 | Base for Supporting an Upstanding Mast - A portable base is provided for supporting an upstanding mast and particularly a davit with a jib where the jib includes a load connecting point arranged such that on application of a load beyond a predetermined limit the spacing of the load connecting point from the mast is reduced to reduce a side load on the base. The base includes bottom and side panels connected edge to edge to form a container with a hollow interior filled by concrete where at least one side by side panels forming a top wall has a sleeve extends from the panel at least partly through the hollow interior to the base. The sleeve which is welded to reinforcing bars passing through the material receives and supports the mast and is held in place by forces contributed both by the set filling material and the panels. | 11-28-2013 |
20140069666 | Helicopter Carried Aerial Fire Suppression System - An aerial fire suppression system for carrying by a helicopter features a liquid storage tank having a longitudinal dimension that equals or exceeds each other dimension of its shape, and an attachment arrangement for suspending the tank in an upright orientation in which the longitudinal dimension of the liquid storage tank depends downwardly away from the helicopter, thereby minimizing the distance to which the tank's contents can shift outward from the aircraft's longitudinal center of gravity for improved aircraft stability. A discharge boom for emitting fire suppressant media is pivotally supported on the tank, and a winch chain connects the tank to the helicopter to reduce allowable twisting of this tethered connection between the tank and helicopter. | 03-13-2014 |
