Abstract: The present disclosure provides systems and methods for electronically providing each of a plurality of content distributors with access to a library of content items, facilitating the selection of a combination of the content items, creating a unique set of links for each recipient-distributor combination, and distributing the selected content and unique links via one or more distribution channels to a plurality of recipients. As each link is associated with both a recipient and a distributor, conversion actions stemming from the selection of a link by a recipient are attributed to the proper distributor. Distributors can create content distribution approaches that can be shared with other distributors.

Abstract: An electronic requisition processing method and system are disclosed. The method comprises the steps of preparing an electronic requisition including a requisition proposal; establishing an electronic list of approvers for the requisition; and at defined times, electronically recalculating the list. Preferably, this list is recalculated after each of at least some of the approvers act on the requisition; and the list is recalculated according to a given set of rules. Also, in the preferred system, the approval process is synchronous, whereby upon submission of the requisition, the requisition is immediately available for approval. Additionally, preferably, when each approver approves, the list is dynamically recalculated to take into account the availability of approvers further down in the list.

Abstract: A work extraction arrangement (10) comprises a cooling assembly (12) for cooling a gas to provide a working fluid capable of doing work. The arrangement (10) further includes storage means (14) for storing the working fluid and a turbine assembly (18) for extracting work from the working fluid. A fluid delivery assembly (16) is also provided to deliver the working fluid to the turbine assembly (18).

Abstract: A heat exchanger (10) comprises a first sheet (12), a second sheet (14) and an additional sheet (30). The first and second sheets (12, 14) are wound around an axis (X), each sheet (12, 14) has hot and cold edges at the hot and cold ends (16, 18) respectively of the heat exchanger (10). The hot and cold edges of the first sheet (12) are-joined to the hot and cold edges of the second sheet (14). The end (12A) of the first sheet (12) is joined to the second sheet (30) by an axially extending join (28) at a position spaced from the end (14A) of the second sheet (14). The end (30A) of the additional sheet (30) is joined to the end (14A) of the second sheet (14) by an axially extending join (28). The additional sheet (30) is thicker and wider than the first and second sheets (12, 14) such that at least one of the hot and cold edges (30C, 30D) of the additional sheet (30) extend beyond the hot and cold edges of the first and second sheets (12, 14).

Abstract: A starter motor for an internal combustion engine has an inertia type pinion mechanism and an axial solenoid 34 which is arranged to prevent pump out of the pinion 48 during start up of the engine.

Abstract: A household energy management system uses measurements of the household electricity supply 4 to identify and to determine the energy consumption of individual household appliances. From these measurements, models can be built of the behaviour of the occupants of the house, the thermal properties of the house and the efficiency of the appliances. Using the models, the household appliances—in particular heating and cooling appliances—can be controlled to optimize energy efficiency; and maintenance programmes for the appliances and for the house itself can be recommended to the householder or arranged with a service company.

Abstract: Fluid flow diffuser has a first divergent duct connected by a sudden enlargement of flow area to a second divergent duct. The enlargement is defined by a fence situated downstream of the downstream end of the first duct. The top of the fence is on a flow perimeter intermediate between the downstream end of the first duct and the upstream end of the second duct, the latter end being defined by the bottom of the fence. An opening defined by the downstream end of the first duct and by the top of the fence gives access to a chamber connected to a pressure less than that at latter downstream end thereby to generate a vortex having a surface bridging the opening and assisting transition of flow from the first duct to the top of the fence. A second vortex formed immediately downstream of the fence assists transition of flow from the top of the fence to the surface of the second duct. The first duct has a rate of divergence low enough to avoid boundary separation.
