Abstract: A hair-removing and exfoliating device is provided with a pair of counter-rotating abrasive surfaces for pressing against the skin to abrade hair there-from and to exfoliate the skin. The surfaces may be adapted for continual alternating movement in counter-rotating directions at the surface of the skin. In the preferred embodiment, two concentric counter-rotating abrasive surfaces are provided, one rotating clockwise and the other rotating counterclockwise.

Abstract: A combination juicer and shaver includes a juicer portion removably receivable in juxtaposition to a shaver portion. The juicer portion includes a juicer for extracting juice from a food item. The shaver portion includes a chamber and a shaver in the chamber for producing shavings of a food item disposed in the chamber. A drive selectively produces operating movement of the shaver means and the juicer, and a coupling communicates the operating movement between the shaver and the juicer.

Abstract: A system for bi-directional digital serial communication and control of remote units including video cameras and input/output devices in machine vision systems. The communication system includes a main processor, communication hubs and remote units. The system is capable of monitoring and controlling the remote units in real-time while receiving video data images from the remote video cameras. Digital signals are transmitted in two different protocols; one for data communications, and one for control communications.

Abstract: A water distribution valve, ideally suited for distributing water from a recirculating pump of a swimming pool to selective outlet lines, is designed with a main housing in the form of an outer cylindrical section. This main housing has outlet ports located through the peripheral surface thereof at equal angular spaced intervals. These outlet openings are located in a plane which is perpendicular to the central axis of the main housing. A fluid distribution member, in the form of a T-shaped body, is rotatably mounted inside the main housing member. The base or stem of the T is connected with a water inlet; and one arm of the T has a fluid delivery opening in it for delivering water from the inlet through the opening.
