  • Patent number: 5954714
    Abstract: Apparatus for thermal coagulation having an improved circulation assembly and heating assembly. The apparatus includes a balloon catheter secured to and in fluid communication with a handle for inserting the apparatus into a human uterus. A distensible bladder is secured to the distal end of the catheter and encloses a heating assembly having a tubular core configured with a spiral groove which retains a heating filament. An impeller having at least two blades is positioned distal of the heating assembly and includes a cable having a distal end secured to the impeller. The impeller cable is partially disposed in the handle, in the elongate tubular member and in the core of the heating element, such that axial rotation of said cable rotates the blades of said impeller. During use of the apparatus, the distensible bladder is inflated with a fluid to a desired pressure and rotation of the impeller blades is initiated.

  • Patent number: 4988097
    Abstract: A combination exercise and refreshment device to be worn about a runner's or other athlete's wrist or forearm that contains liquid, the weight of which provides vigorous exercise to the muscles of the hands, arms and shoulders during the earlier part of the run or other aerobic exercise and the liquid serving to be drunk to replenish lost body fluids during the latter part of the exercise and reduce stress on the fatigued muscles comprising a liquid-containing pouch adapted to fit around the wrist, a fastener for attaching the pouch around the wrist, and a valve for introducing and withdrawing the liquid from the pouch directly into the user's mouth.

  • Patent number: 4773571
    Abstract: A package (10) for dispensing a fluid (26) in the package under gas pressure has a biaxially oriented polyethelene terepthalate bottle (12) with a neck (14). A dispensing head (22) is attached to the neck (14). A normally closed valve (16) is mounted in the neck and has a housing (50) sealed to the inside surface of the neck (14). The housing (50) has a syphon flange (54). An integral structure (56) having a spring (58) at one end and a poppet (60) at a second end rests on the syphon flange (54). The housing has an opening (48) above the syphon flange 54). The integral structure (56) extends between the syphon flange (54) and the opening (48). The integral structure (56) is dimensioned so that the spring (58) is compressed to bias the poppet end of the integral structure (56) into sealing engagment around the opening (48). The dispensing head (22) has an integral diaphragm (42) and rods (52) and (46) extending above and below the diaphragm (42).

  • Patent number: 3992697
    Abstract: A character recognition system comprising means for scanning a character on a document field, the field being composed of plural features each of which lies in a respectively defined area on the character. A pair of video shift registers, one for positive video and one for negative video, are provided to shift the signals therethrough. Each video shift register includes a plurality of stages for serially storing and shifting a binary quantization of a character pattern sample within said field. Feature extraction logic circuitry is provided and includes a plurality of feature detecting means to provide signals indicative of the recognition of predetermined features as the character pattern is shifted through selected stages of the video shift register. The detecting means include plural mask matrices coupled to said video shift registers.
