Abstract: A method that incorporates teachings of the present disclosure may include, for example, the steps of transmitting media content to a group of set top boxes for presentation with an overlay superimposed onto the media content, where the overlay can include a timeline corresponding to the presentation of the media content and receiving a first comment from a first set top box of the group of set top boxes, where the first comment is presentable with the overlay and the media content by the group of set top boxes. Additional steps can include receiving a tag generated at a first set top box during presentation of the media content, presenting the tag while the media content is presented, correlating the tag to a portion of the media content timeline and analyzing metadata associated with the portion of the media content timeline that is tagged to determine a first marketing parameter. Other embodiments are disclosed.

Abstract: A reusable apparatus for multiphase, multistage countercurrent liquid separation is presented. The apparatus is particular useful in progressive multistage separation of target microorganisms from background organisms and materials with precise transfer, air exclusion, homogeneous mixing, isolation from the ambient atmosphere, in the absence of valves and at ow cost. The structure has at least one chamber in which a piston-like sliding bottom is sealingly moved or braked and includes internal structure for mixing, preferably a magnetic-stainless steel ball which can be reciprocated from the outside to mix the liquid contents. Motion of the bottom is limited by stops. A number of ways to actuate the apparatus are taught.

Abstract: A clamping jig releasably holds a workpiece of elongate cross section such as a radiator core. The jig includes an upright frame and a parallelogram-shaped horizontal articulated linkage having a pair of parallel side rails and a pair of end members pivotally connected to the ends of the side rails for movement about vertical axes. The side rails are spaced apart a distance greater than the width of a radiator core, and are moved by a pneumatic cylinder or other actuator so that the links pivot about their axes, and the side rails move closer together to clamp the radiator core between them. The clamping mechanism is operated by a foot pedal, for hands free operation. The vertical height of the parallelogram linkage may be readily adjusted, and hold-down elements are provided to exert a downward pressure on the radiator when it is held clamped between the side rails.
