Abstract: A displacement pump is configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A flange projects from a pump body of the pump and a ring projects from the pump body of the pump. A portion of the drive housing is received in a gap between the flange and the ring.

Abstract: A fluid spraying system includes a displacement pump configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring that includes threading is configured to rotate about a cylinder of the pump and shift axially along the cylinder and engage with a bottom side of the drive housing to secure the displacement pump to the drive housing.

Abstract: A tank fill adapter device for a portable fluid tank provides a connection between an inlet collar of a tank and a supply pipe for filling the tank with a fluid that introduces an air gap into the connection. An annular mounting flange mounts against the inlet collar using a fastened connection. A pipe supporting portion protrudes upwardly from the annular mounting flange for supporting an open end of the supply pipe spaced above the inlet collar. An outer annular baffle protrudes downwardly from the annular mounting flange for being received into the tank through the inlet collar and an inner annular baffle is supported within the outer annular baffle to define a generally annular space between the outer and inner annular baffles which remains in open communication at a bottom end thereof with an interior of the tank.

Abstract: Methods and apparatus for detecting the possible rejection of a transplanted tissue by a host. The transplanted tissue is subjected to illumination with light to induce fluorescence. The light can be ultraviolet light, visible light or infrared light, which can be used alone or in any combination, which means one, two or three forms of light may be used together. The induced fluorescence is collected and analyzed, then compared with fluorescence that is obtained using the same procedure for a known, healthy tissue that is the same type of tissue as the transplanted tissue. Also provided are methods and apparatus related to the determination of probe orientation and the need for biopsy.

Abstract: The present invention provides umbilical cord clamps that comprise two or more different colors at the distal end of each of the elongated arms of the clamps. The colors are complementary to each other so that, when combined, they create a third color.
