Abstract: A system for reducing internal combustion engine emissions includes an engine, a catalytic converter fluidly connected to a combustion chamber via an exhaust line, a glow plug positioned along the exhaust line between the catalytic converter and the combustion chamber, and a flame accelerator, without a fluid connection to a separate fuel supply. Methods of using the system include igniting a mixture of air and fuel in the exhaust line using the glow plug, producing an amount of heated combustion gas.

Abstract: An aeration system for aerating particulate material disposed in a storage bin. The aeration system includes an aerator forming an elongated hollow body for being placed inside the storage bin such that a longitudinal axis thereof is oriented substantially vertical and an air supply duct connected to the aerator for providing the airflow thereto. The aerator enables an airflow therein along the longitudinal axis and provides the same to the particulate material. The aerator is made of a plurality of modular sections adapted for being stacked upon each other along the longitudinal axis. Each modular section has a bottom connecting element and a top connecting element placed at a bottom end and a top end thereof, respectively, with the top connecting element being mated with the respective bottom connecting element of an adjacent modular section. Each modular section has a conduit enabling the airflow along the longitudinal axis.

Abstract: A locking device for preventing freewheeling of an aeration fan rotor. The locking device comprises an elongated body having a predetermined length. The elongated body is adapted for being disposed through an opening of a fan housing containing the aeration fan rotor therein such that in a first position a first end portion of the elongated body is enabled to interact with the aeration fan rotor for preventing freewheeling of the aeration fan rotor and a second opposite end portion of the elongated body is placed outside the fan housing. The locking device further comprises means for holding the elongated body in the first position and a second position such that in the second position the first end portion of the elongated body is prevented from interacting with the aeration fan rotor.

Abstract: The cooling system includes a jacket disposed at least partially around a combustor having a combustor channel opening. The jacket includes a slot having an opening oriented towards a downstream end of the combustor. The slot may include a width ranging from around 0.5% to around 100% of a width of the combustor channel opening. The slot accepts a coolant through the opening of the slot.

Abstract: A fan including a housing having an air inlet and an air outlet. An impeller is disposed in the housing and driven by a motor connected thereto. A connecting mechanism is disposed on the housing in proximity to the outlet. The connecting mechanism is adapted for being mated with a respective connecting structure.

Abstract: A flow measurement apparatus comprising an elongated mounting stem having an inner stem cavity, the mounting stem configured to be mounted in an area of flow to be measured. A probe housing is mounted to an outer surface of the mounting stem and positioned on an upstream side of the mounting stem. The probe housing has a first hole near a center point of the housing and a second, third and fourth hole positioned near the perimeter of the housing. A fifth hole is located on a downstream side of the mounting stem. At least five pressure sensors and a plurality of pressure tapping tubes connecting the holes to the corresponding pressure sensors are included.

Abstract: A tip structure for a turbine blade comprises a tip surface of an airfoil that extends from a leading edge to a trailing edge and from a pressure side to a suction side of the airfoil. A suction side rail protrudes from the tip surface and comprises: a trailing portion extending flush with the suction side of the airfoil from an origination location at or near the trailing edge to an intermediate location on the suction side; and a leading portion extending from the intermediate location across the tip surface so as to create a suction side shelf region between the leading portion of the suction side rail and the suction side of the airfoil.

Abstract: A system for controlling access to enterprise software on a premised-based server or running as a cloud service for a plurality of end users that includes a first tier Administrator, a second-tier Administrator, a user interface, a database, and a per seat license. The first-tier Administrator identifies a community that can access the cloud service and an upper limit of end users that can belong to the community. The second-tier Administrator is selected by the first-tier Administrator. The second-tier Administrator can create at least one Organizational Unit that is a subset of the end users within the community. The user interface includes all the Organizational Units, and each Organizational Unit corresponds to a particular cloud service. The database is controlled by the first-tier Administrator, and it controls the end users that can access the cloud service.

Abstract: An illustrative system for managing a plurality of cloud services that includes a first cloud service, a second cloud service, a relational database, a cloud management console, a global user profile, an invitation, and a synchronization module. Each cloud service includes an LDAP directory configured to manage end users accessing the corresponding cloud service. The relational database is communicatively coupled to each LDAP directory. The cloud management console manages the relational database, which identifies a maximum number of end users that can access each cloud service and an end date for accessing each cloud service. The global user profile is stored on the relational database. The invitation communicated from the cloud management console enables an end user to access the cloud service. The synchronization module enables the relational database to synchronize with each of the LDAP directories according to each end user's accepted invitations.
