A lighting system is provided whereby long operating life can be reasonably ensured by taking into account requirements of the application, characteristics of the LEDs, characteristics of the fixture containing said LEDs, the desired number of operating hours, and—via developed relationships—taking an iterative approach to supplying power to the LEDs. Through the envisioned compensation methodology and effective luminaire design, a relatively constant light level can be assured for a predetermined number of operating hours (possibly longer); this is true even if operating conditions change, known behavior of LEDs proves untrue over untested period of time, or some other condition occurs which would otherwise cause end-of-life prematurely and prevent the system from meeting the desired number of operating hours.

A combustion chamber of a combustion system comprises a combustion space, a support structure, a heat shield, and at least one through-opening. The heat shield has at least two segments, and each segment has an edge region, a gap communicating with the combustion space being formed between edge regions of adjacent segments, and a retaining device. The adjacent segments include a support element disposed in a bottom region of the gap. The retaining device fixes the respective liner element on the support structure via the respective support element. The at least one through-opening communicates with the gap so as to enable a cooling gas to flow through the through-opening. The at least one through-opening is disposed in at least one of the respective edge region and the support element at the bottom region of the gap.

Also provided is a lapboard siding and trim system in which siding components for clapboard siding are manufactured by extruding wood / thermoplastic resin composite material through a die. Associated trim components are manufactured using the co-extrusion process described above. The siding and trim components are completely waterproof, and installation proceeds with almost no face nailing and almost no caulk.

An inner lining for the steel shell of a carbothermic reduction furnace for the production of alumina has a base layer of graphite and a coating layer of refractory material. The refractory material is corundum (Al2O3) bound by Sialon (Si.Al.O.N). The lining structure provides protection against the molten slag and it is not attacked by the CO-rich melt furnace atmosphere. Further, the lining does not contaminate the melt and it provides an effective heat dissipation system in case of a power shut-off.

The present invention is drawn to inertial type transducers and a system for reducing the complexity and difficulty of installing the transducers internal to a structure. The transducer is equipped with a wireless receiver for receiving both sound content signals and control signals, and an amplifier, along with a power supply. Because the amplifier is activated by the wireless receiver, there are no wires necessary to connect the transducer to the source of the sound content or control signals thereby vastly simplifying installation. Heat dissipation and height minimization are also addressed.

The cups and containers also have an inner concentric structure that follows the shape of the cup or container just above the base to offer stabilization, and ease of stacking, removal, and manufacture.

In the repair of a blisk or blisk drum, the damaged airfoils are completely cut off at the same low-stress nodal line peculiar to the respective blade type, except for a blade stump (2), and are each replaced by a new blade repair element (3) of a same shape and size which is accurately clamped onto the blade root by a ledge (5) formed onto its mating end, with this ledge (5) also serving for fixation of the processing fixtures and stabilization of the thin airfoil, and is then welded to the blade root and subsequently subjected to a cutting or non-cutting operation for removal of the ledge (5). This highly efficient repair method can similarly also be applied to the new manufacture of blisks.

The current invention relates to encapsulation methods comprising alginate-based microencapsulation for the immune-protection and long-term functioning of biological material or therapeutics. The biological material or the therapeutics are encompassed by a membrane formed by jellifying an alginate polymer. Specifically, although by no means exclusively, the encapsulation system is intended for use in allo-or xenotransplantation. The membrane provides for a protective barrier of the encapsulated material, ensuring the longevity and preventing unwanted influences from outside the barrier, such as inflammatory reactions or immune-responses. The invention is furthermore directed to methods of producing and providing the encapsulated products for use in cell therapies. The therapeutic products obtained by the encapsulation method may provide a method for ameliorating of treating a range of conditions.

A system for structuring credit support in connection with life insurance premium finance loans and securitizing longevity risk includes a trust having a life insurance policy and a premium finance loan from a lender that finances the cost of the premiums of the life insurance policy. The life insurance policy is used as collateral for the premium finance loan. The trust provides to the lender additional collateral in the form of a letter of credit or other forms of collateral to cover any shortfall between the balance and the policy cash surrender value. A longevity risk fund provides the credit support by entering into a collateral support agreement with the trust through a credit source. The longevity risk fund receives compensation in the form of risk adjusted return on exposure, in exchange for providing the additional collateral. The cash flows received from the credit support obligations are then securitized through the transfer of the related collateral support agreements (either by legal transfer or economic participation) to a special purpose vehicle that issues securities (either equity or debt) to the capital markets.

Unattached elastic portions of an elasticised web are grasped and raised above a support surface for feeding the elasticised web. The raised portions are brought into contact with a knife blade that is positioned to protrude through the thickness of the raised elastic layer into free space so as to remain spaced from the support surface that is moving beneath the blade in a direction normal to the support surface. The raised elastic layer is held raised during trimming with the knife blade by an elevation element over which the elastic layer runs. A grasping device holds the unattached portion being cut in a taut state in the cross machine direction. The elastic layer thus spans across the elevation element and the grasping device. The knife blade extends through the thickness of the elastic layer along the spanned part of the elastic layer into free space.
