20090130475 | Wood treatment solution and process - The present invention features a single aqueous solution that imparts acceptable levels of water resistance, fire resistance, mold resistance and pest resistance to wood, and which may be used in standard wood treatment techniques commonly utilized in the wood treatment industry. In one preferred embodiment, the aqueous solution comprises a fire retardant, preferably sodium metasilicate nonahydrate (about 5% to 30% by mass), an insect and termite repellant, preferably sodium tetraborate decahydrate, also known as borax, (about 1.5% to 9% by mass), a mold inhibitor, preferably thymol (about 0.01% to 0.1% by mass) or ethanolamine (about 0.5% to 20% by mass), and a pH buffer, preferably sodium carbonate (about 1% to 10% by mass). It is believed that the borate/silicate components polymerize upon drying, and become water insoluble, which in turn prevents leaching and provides water repellent characteristics to the wood after treatment. It has been observed that the sodium carbonate may also act as a mold inhibitor, so that the ethanolamine and thymol may be optional ingredients in the solution. The calcium carbonate, in addition to serving as a buffer and imparting some mold and mildew inhibiting properties, is thought to also serve as a catalyst that maintains the water solubility before and during the immersion (impregnation) step, and helps to polymerize the silicate/borate compounds during the drying step. The aqueous solution should have a pH in the range of 9.5 and 13. Additionally, a powder mixture of the above-recited components may be prepared, and may be added to an appropriate amount of water to form the aqueous solution. | 05-21-2009 |

20090005804 | TRAINING TOURNIQUET AND METHOD OF USE - A training tourniquet for use in training a user or another person, such as a medic, includes a non-functioning tensioning mechanism to model application of developing a tensile force in a strap of a tourniquet. The training tourniquet has particular application to training field personnel, such as medics and soldiers as to how to apply a tourniquet, without actually creating a compressive force that could damage a person's tissue during the training or practice sessions. In one embodiment, an inoperative windlass can be rotated to simulate the action necessary to create tension in a strap of a real tourniquet, however, the inoperative windlass spins around without actually tightening a strap of the training tourniquet. | 01-01-2009 |
20090062842 | TOURNIQUET AND METHOD OF USE - A tourniquet for restricting a flow of blood in a body part comprises a first elongated member, and a second elongated member in slidable engagement with the first elongated member. In addition, the tourniquet includes a tensioning mechanism connected to the second elongated member, wherein a compressive force is applied to the body part upon applying a tensile force to the second elongated member using the tensioning mechanism. At least one embodiment of the present invention comprises a buckle having one or more of a raised intermediate bar and one or more teeth for contacting a portion of the first elongated member. The tourniquet is suited for emergency use, and may be applied by using only one hand. Thus, the tourniquet may be applied, manipulated and tightened by the wearer, even if the wearer is limited to the use of a single hand. | 03-05-2009 |

20090256380 | TARPING SYSTEM - An apparatus is provided for tarping a cargo loaded on a flat bed vehicle which includes a pair of ruggedly constructed double scissors linkages carried by an overhead horizontal traveling trolley and connectable at their lower ends to the tarpaulin. A vertically adjustable horizontal roller is provided, over which the tarpaulin is pulled during its installation in covering relation to the loaded cargo. | 10-15-2009 |
20100307868 | RETRACTABLE ACCESS PLATFORM - An apparatus for providing access to vehicles and containers on a pair of railways or thoroughfares. The apparatus is comprised of a raised walkway between the pair of thoroughfares having a tracking platform movable thereon. Pivotally attached to and carried by the tracking platform is a turret. Carried on the turret and hinged thereto is a bridge that is rotatable in a vertical plane. At the end of the bridge is a cage pivotally attached to the bridge so that the cage remains horizontal when the bridge is rotated vertically on the turret. The bridge and cage are dimensioned so that, when the turret is rotated such that the bridge is directed between and parallel to the thoroughfares and the bridge and cage are raised, the apparatus is entirely out of the clearance envelopes of the thoroughfares. | 12-09-2010 |
20110078864 | EXTENDED SAFETY CAGE FOR RETRACTABLE GANGWAY - An extended safety cage provides access to a plurality of hatches on the top of a mobile container. The cage is rotatably attached to the end of a gangway, which extends from and is rotatably attached to a platform. The platform carries a pair of braces that extend out in opposite directions and support the cage through spring-loaded lifting arms. The apparatus can include actuators, such as hydraulic or pneumatic actuators, that urge the gangway and cage downward when activated. Secondary braces ensure that the lifting arms and safety cage move in unison. | 04-07-2011 |
20110127111 | TRACKING GATE FOR EXTENDED GANGWAY - An apparatus for providing safe access to a top of a mobile container. The mobile container has a top, a longitudinal dimension, and a plurality of hatches arrayed along the longitudinal dimension on the top. The apparatus has a raised platform and an extended cage attached to the raised platform wherein the extended cage extends along the longitudinal dimension. A tracking gate, attached to the extended cage, is adapted to vary an effective interior size of the extended cage. | 06-02-2011 |
20120042458 | PIVOT BLOCK CONNECTION - A pivot block connection and assembly is disclosed. The pivot block assembly may include a pivot block connection and a gangway device having a stationary base and a pivotable access that is capable of being raised and lowered. The pivot block connection may include a first support body attached to a first side of the pivotable access, a first pivot bracket attached to the stationary base, and a first pivot rod spacer positioned between the first support body and the first pivot bracket. The pivot block connection may also include a second support body attached to a second side of the pivotable access, a second pivot bracket also attached to the stationary base, and a second pivot rod spacer positioned between the second support body and the second pivot bracket. A pivot rod may extend through the first pivot bracket, the first pivot rod spacer, the first support body, the pivotable access of the gangway device, the second support body, the second pivot rod spacer, and the second pivot bracket to secure and allow pivotable rotation of the pivotable access. | 02-23-2012 |
20120056364 | ADJUSTABLE WORK SURFACE FOR LARGE IRREGULARLY SHAPED OBJECTS - An adjustable work platform comprises a fixed platform carrying a multiplicity of adjustable members designed to slide out of the fixed platform to variable lengths as needed. A large irregularly shaped object, such as an aircraft, may be driven into the interior of the platform with the adjustable members retracted. Once in place, the adjustable members are extended to form a heavy duty work platform conforming to the irregular shape of the exterior of the object. | 03-08-2012 |
