Abstract: New intracorporeal radiodense medicaments and certain medical uses and methods for use of such high energy phototherapeutic medicaments for treatment of human or animal tissue are described, wherein a primary active component of such medicaments is a halogenated xanthene or halogenated xanthene derivative. The halogenated xanthenes constitute a family of potent radiosensitizers that become photoactivated upon irradiation of the treatment site with ionizing radiation.

Abstract: New intracorporeal photodynamic medicaments and certain medical uses and methods for use of such photodynamic medicaments for treatment of disease in human or animal tissue are described, wherein a primary active component of such medicaments is a halogenated xanthene or halogenated xanthene derivative. In preferred embodiments, such medicaments are used for treatment of a variety of conditions affecting the skin and related organs, the mouth and digestive tract and related organs, the urinary and reproductive tracts and related organs, the respiratory tract and related organs, the circulatory system and related organs, the head and neck, the endocrine and lymphoreticular systems and related organs, various other tissues, such as connective tissues and various tissue surfaces exposed during surgery, as well as various tissues exhibiting microbial or parasitic infection.

Abstract: New photodynamic, topically-applicable medicaments and certain medical uses of such photodynamic medicaments for treatment of human or animal tissue are described, wherein a primary active component of such medicaments is a halogenated xanthene. The halogenated xanthenes constitute a family of potent photosensitizers that become photoactivated upon illumination of the treatment site with visible wavelengths of light. In preferred embodiments, such medicaments are used for treatment of a variety of conditions affecting the skin and related organs; the mouth and digestive tract and related organs; the urinary and reproductive tracts and related organs; the respiratory tract and related organs; various other internal or external tissue surfaces, such as tissue surfaces exposed during surgery; and for treatment of a variety of conditions related to microbial or parasitic infection.

Abstract: A torsional vibration damper assembly for the transmission of power in a torsional coupling or automotive vehicle clutch wherein the coil springs normally disposed between the driving and driven plates of the assembly are replaced by one or more bowed leaf springs to provide a non-linear elastic system.

Abstract: A controlled lock-up clutch interposed between the impeller and turbine in a torque converter of an automatic transmission for an automotive vehicle where the clutch lock-up and unlock is controlled at a torque converter speed ratio design point by the stator movement and loading. A lock-up clutch is actuated from a hydraulic source and controlled by a rotary valve that is actuated by a one-way overrunning clutch positioned between the stator of the torque converter and the rotary valve movable between two control positions.

Abstract: A trench shoring assembly including first and second spaced walls having upper surfaces with third and fourth spaced walls stacked upon the upper surfaces of the first and second walls. A plurality of tubular collars project from the various walls and are aligned vertically at each end thereof. Spreader pipes interconnect these collar projections at one end of the assembly and a spreader assembly interconnects the stacked walls at the other end. More specifically, the spreader assembly includes vertically extending metal beams interconnecting the collars projecting from the walls and tie bars extending between the vertical beams at a position spaced well above the upper surfaces of the lower walls thereby facilitating a pipe having a diameter which is greater than the vertical height of the lowermost walls.

Abstract: This invention relates to a trench shoring assembly which includes a pair of spaced apart side walls for vertical disposition within a trench. Spreader pipes and spreader collars interconnect the side walls and allow limited pivotal movement between the wide walls. Each side wall includes outer and inner metal plates connected to a plurality of interconnected structural members which define a main frame. The interconnected structural members include horizontally extending hollow metal beams including a top beam which extends longitudinally along the top of the side wall, two intermediate beams parallel the hollow metal beam and a bottom beam. A hardwood insert is disposed within the top beam to prevent the collapse of the hollow metal beam. Each side wall contains a number of hollow beams extending perpendicularly to the horizontal beams and ribbed members extending perpendicularly to the horizontal beams. These vertical beams and members are interconnected by a strip member.
