摘要： In an oil fired boiler (with a combustion chamber and a burner which blows a flame into it) there is a J-shaped heat-exchange duct, built on the combustion chamber floor out of thermally ultra-conductive and non-corroding pipes and fittings. Because of the extreme rigidity and brittleness of these, our structure is designed with masonry-like constraints on duct layout: Must rest on floor--never two attachments to anything--must not rely wholly on cement for stability.The J-duct becomes hot from the radiation in combustion chamber. It serves to heat secondary air and delivers it at suitable discharge regions from which it will join the base of the entering flame.The tip of J's long leg is outside chamber and gets secondary air from blower. This leg extends into chamber through its front wall then, curving around, its short leg extends forward and ends at location next to front wall's hot face. The heated air is either discharged at this location through an orifice, or else is carried up in a tower-like riser duct and discharged at a higher discharge point almost directly above the location where the short leg ends.

摘要： A needle adaptor (10) for connecting a needle (20) to an electrosurgical tool (56). The adaptor (10) includes a stem 12, an integrally formed post (14) and a collar (16) press-fitted on the stem (12). An annular ridge (50) or a spiral ridge (54) formed on the interior surface (32) of the collar (16) grips the flange (42) of the needle hub (22) to firmly hold the needle (20) in place on the post (14). The stem (12) is sized and shaped to be slidably received within a cylindrical terminal (64) positioned in the nose portion (60) of the electrosurgical tool (56).

摘要： A transparent shield for the electrode of an electrosurgical device. The shield is designed to prevent the spray of blood and splatter of tissue generated during electrosurgery from being deposited upon the surgeon using the device and is particularly adapted to protect the face and eyes of the surgeon against contact by such airborne fluids and particles. The shield is adapted to be mounted upon a wide variety of electrodes or electrosurgical instruments and may be curved for use with curved electrodes. The shield may also be curved in the transverse direction along its length to better confine spray and splatter.
