Abstract: An implantable electrical connector includes a male portion and a female receptacle. The male portion includes a number of wires that terminate in a pattern of conductive areas. The male portion is inserted into a female receptacle and guides in the female receptacle limit the insertion of the male portion to a single direction. A locking mechanism such as a setscrew on the female receptacle forces conductive areas of the exposed conductors onto connecting pins within the female receptacle. The setscrew itself is electrically isolated from the conductive areas. Each pin in the female receptacle is surrounded by a rigid seal that engages a compressible insulating member under compression of the locking mechanism to prevent an electrical connection forming between adjacent pins in the connector.

Abstract: The dispenser provides for accurate and easily repeatable dispensation of selected volumes of paint colorant. The dispenser has an adjustable stop for limiting the travel of a piston in a paint colorant metering pump. The stop position can be adjusted in equally spaced increments by a coarse adjustment which includes a pin which may be engaged in equally spaced holes in a stop support member. The stop position can be adjusted to intermediate positions by a fine adjustment. The fine adjustment includes a threaded stop member mounted in a threaded aperture. The pitch of the threads on the stop member is such that the stop moves a distance of one increment in a single rotation of the stop member. The stop member may be turned by a knob. The knob is slidably mounted so that it does not move axially with the stop member and has a limited rotation so that each position of the knob corresponds to only one stop position.
