Abstract: The invention relates to a seal system comprising a stationary assembly having an angled profile, and a rotary assembly comprising a resiliently flexible rotary elastomeric member. When in a rest position, the rotary elastomeric member contacts the angled profile of the stationary assembly to seal a gap therebetween. On rotation of the rotary elastomeric member, the gap between the assemblies is opened to allow fluid flow therethrough.

Abstract: A mechanical seal includes an elastomeric member, a spring biasing member, a longitudinally floating first member, a longitudinally non-floating second member, a longitudinally floating third member and a longitudinally floating seal face. The elastomeric member is in sealing engagement with the seal face and the first and second members and the spring biasing member is longitudinally pointed between the seal face and the third member. The first and second members are longitudinally restrained and rotationally coupled by male longitudinally protruding portions engaging with female portions.

The elastomeric member is in sealing engagement with the first member, second member and third member and the spring biasing device is longitudinally positioned between the first member and the second member. One of either the first member or the second member is provided with at least one protruding male portion and the other member of either the first member or the second member is provided with corresponding female portion into which the male portion locates.

Abstract: A mechanical seal support system includes a bladder accumulator with a first connection to the top of the bladder accumulator and a second connection to the bottom of the bladder accumulator with a device that is responsive to the pressures at each of the first and second connections of the bladder accumulator for providing an output determined by the difference between the pressures. The mechanical seal support system further includes a display for displaying the output in a manner indicative of the volume of the fluid in the bladder accumulator relative to a predetermined volume.

Abstract: A mechanical seal for providing a fluid-tight seal between relatively rotatable elements includes a stationary part for securing to a housing, which has a stationary seal face, a rotary part for securing to a shaft, which includes a rotary seal face, a spring urging the rotary seal face into engagement with the stationary seal face and a toroidal sealing member between the rotary component and the shaft. The toroidal sealing member is accommodated within a recess of the rotary part, and the recess is defined by two members of which the first rotary part member includes the seal face and a second rotary part member is positioned between the first rotary part member and the spring.

Abstract: A mechanical seal support system includes a pre-pressurized bladder accumulator containing a barrier fluid and a gas under pressure. A cooling circuit includes a mechanical seal for feeding the barrier fluid from the accumulator to the cooling circuit with a pressure regulating device located between the accumulator and the cooling device. A device, responsive to the pressure in the cooling circuit, for indicating when an actual pressure is below a predetermined pressure level is included.

Abstract: A method of and system for transmitting video images preferably allows a specially trained individual to remotely supervise, instruct, and observe administration of medical tests conducted at remote locations. This system preferably includes a source device, a transmitting device, and at least one remote receiving device. The transmitting device, and the remote receiving device communicate over a network such as any appropriate data network. The transmitting device transmits the video images to the remote receiving device either for live display from the source device or for pre-recorded display from a video recorder device. The remote receiving device is also capable of communicating with the transmitting device while simultaneously receiving video images to provide remote control. The source device is preferably a medical test device such as an ultrasound, a sonogram, an echocardiogram, an angioplastigram, and the like.
