Abstract: A fuel primer is disclosed. The primer includes a rigid valve body having first and second ends with first and second check valves therein. The pump also includes an elastic and substantially fuel impermeable bulb substantially encasing the rigid valve body and sealing to the valve body proximate the first and second check valves.

Abstract: Drill bits and cutting elements having a functionally-engineered surface comprise a cermet material selected from the group consisting of refractory metal carbides, nitrides, borides, carbonitrides and mixtures thereof. A functionally-engineered material is disposed over a surface portion one of the cutting elements to form a wear resistant surface thereon having a hardness that is different than that of the underlying cutting element. The wear resistant surface is provided by forming a conformable material mixture by combining one or more powders selected from the group consisting of cermets, carbides, borides, nitrides, carbonitrides, refractory metals, diamond particles, cubic boron nitride particles, Co, Fe, Ni, and combinations thereof, with an applying agent. The applied material mixture is pressurized under conditions of elevated temperature to consolidate and sinter the material mixture, thereby forming the wear resistant surface having desired properties of hardness and/or fracture toughness.

Abstract: Methods and apparatuses for programming content reconstruction in a content delivery system are described. In one embodiment, a method to repair programming content at a receiver controller includes receiving a programming content on the receiver controller from a broadcast transmission; identifying, if present, a portion of the programming content received on the receiver controller that is corrupted; determining in a broadband network, other servers and receiver controllers connected to the broadband network that have an uncorrupted version of the corrupted portion of the programming content; sending a request to one of the other servers and receiver controllers for the uncorrupted version of the corrupted portion of the programming content and receiving the uncorrupted version of the corrupted portion of the programming content from the one of the other servers and receiver controllers. Other embodiments are also described.

Abstract: A bit body formed of a mixture of matrix material and superabrasive powder and including pockets lined with superabrasive-free matrix material, and a method for forming the same, are provided. The pockets are shaped to receive cutting elements therein. The superabrasive-free matrix material enhances braze strength when a cutting element is brazed to surfaces of the pocket. The method for forming the drill bit body includes providing a mold and displacements. The displacements are coated with a mixture of superabrasive free matrix-material and an organic binder. The mold is packed with a mixture of matrix material and superabrasive powder and the arrangement heated to form a solid drill bit body. When the solid bit body is removed from the mold, pockets are formed by the displacements in the bit body and are lined with the layer of superabrasive-free matrix material. The superabrasive material may be diamond, polycrystalline cubic boron nitride, SiC or TiB2 in exemplary embodiments.
