Seal ring assemblies for use with rotary valves and methods to manufacture the same are disclosed. A seal ring assembly is described that includes a ring-shaped seal to be fixed within the rotary valve, where the seal enables the sealing engagement of a control member with a flow control aperture. The seal is compressed between a first seal clamp and a second seal clamp by a compressive force maintained by a plurality of fasteners extending through the seal and fixed to the first and second seal clamps.

A method of numerically controlled grinding for forming a curved profile on a workpiece. A rotary grindstone having an arc-shaped grinding periphery. The rotating grindstone is moved along the target profile of the workpiece as keeping a constant attitude thereof as far as such a condition is satisfied that the spotty contact of the arc-shaped periphery of the grindstone to the target profile is maintained. Immediately before the satisfaction of the condition expires, the attitude of the grindstone is reset to satisfy the same condition.

Fireplaces suitable for outdoor patio and built-in fireplaces, fire pits and the like that burn biomass solid particulate fuels wherein such fireplaces comprise at least one feed system that is modular which can feed from at least one feed bin onto one or more burn grates. This allows for greater control over aspects such as heat output, energy generation, mixing different varieties of fuels such as flavored pellets or chips when used in a barbecue grill or smoker or other food preparation device, and if desired a wider, more full flame for example where aesthetic considerations are important.

The interlocking interior trim is a modular baseboard system that may be installed without using additional specialized tools or materials. The baseboard sections are stackable, and will connect to each other before being secured to the wall. The interlocking trim can be used around the walls of a room or along a staircase. When used along a staircase, the sections are cut at an angle to allow the system to run parallel to the slope of the stairs.

A method to generate a quincunx video stream is disclosed. The method includes generating a first-type quincunx field from a first high resolution video frame. The first-type quincunx field has a plurality quincunx pixels, each of which has an associated pixel in the first high resolution video frame. The quincunx pixels are calculated using a smoothing filter and a pixel block containing the associated pixels and other high resolution pixels near the associated pixels. A second-type quincunx field is generated from a second high resolution video frame.
