A sofa bed having a friction damper on the main angle of the bed frame, which prevents the front tube and front legs of the frame from rapidly swinging forward as the frame is opened to prevent injury to the operator.

The rolling mill has two working rolls and at least two supporting rolls. At least both rolls of one roll pair are axially slidable opposing each other and each of the oppositely slidable rolls has a curved contour extending over its entire length which is convex over one longitudinal half segment and concave over the other longitudinal half segment. The contours of both rolls of these roll pairs ...

An electrosurgical technique of achieving coagulation involves conducting a predetermined ionizable gas in a jet to the tissue at a predetermined flow rate sufficient to clear natural fluids from the tissue and to substantially expose the tissue stroma. Electrical radio frequency energy is conducted to the tissue in ionized conductive pathways in the gas jet. To achieve fulguration, the electrical...

An automated system is provided for selectively separating resin pellets having a gel count below a specified maximum from pellets having a gel count above the specified maximum, while the pellets are flowing in a pneumatic conveyor. The separation is based on an essentially continuous measurement in which a laser beam is utilized to detect the number of gels in a film made from pellets withdrawn ...
