Abstract: Techniques are provided herein for tracking activation events associated with a given serial number and using the data from the activation events to autonomously determine whether the serial number has been leaked. Numerous different characteristic parameters of activation events collected over a given time period for a serial number can be tracked and stored in a database. A plurality of different input variables can be generated based on the characteristic parameter data, which create the inputs that are used by a trained neural network to determine the leakage probability. If the leakage probability is determined to be above a certain threshold, an alert of some kind can be generated to indicate that the serial number has been leaked.

Abstract: A method and catalytic systems for treating a gas to reduce nitrogen oxide emissions are disclosed. The catalytic systems can include a catalytic composition which comprises an active phase on a support. The active phase is based on rhodium in the form RHx+ and at least another element selected among palladium and platinum and the support is based on cerium oxide and zirconium oxide. Gases capable of being treated by the method and the catalytic systems include in particular those derived from gas turbines, from gas-fired or coal-fired stream plant boilers, or from internal combustion engines.

Abstract: The invention concerns a method for treating a gas to reduce nitrogen oxide emission. Said method is of the type using a catalytic composition comprising an active phase on a support and is characterised in that the active phase is based on rhodium in the form Rhx+ and at least another element selected among palladium and platinum and the support is based on cerium oxide and zirconium oxide. Gases capable of being treated by said method include in particular those derived from gas turbines, from gas-fired or coal-fired steam plant boilers or from internal combustion engines.

Abstract: A socket cavity formed in a concrete slab of the type poured horizontally and subsequently tilted up, which cavity affords engagement of hoisting equipment to the slab. The inner portion of the cavity is in the form of a frusto-conical wall surface communicating with the surface of the cavity through a cylindrical bore concentric with the frusto-conical surface. The cavity is formed by placing in the slab form an expendable flask-like hollow article formed of synthetic resin or the like which is left in the slab after erection thereof. Engaging apparatus cooperable with the cavity which has on the inner end thereof arms that are pivotally moveable between a retracted position and an extended position, the arms engaging the frusto-conical wall of the cavity when in the extended position.

Abstract: A hanger for suspending concrete forms from a beam or other support. The hanger is provided with cast ends which have screw threaded openings proximate their upper portions for receipt of a tension rod and non-threaded sockets proximate their lower portions for receipt of a compression strut. The ends are also provided with openings for the receipt of support rods used to suspend forms from the hanger and these openings accommodate the suspension of such support rods at varying angles relative to the ends.
