A liquid temperature controlling method and apparatus are provided in which on/off valves are utilized. The on/off valves are housed in a compact manifold assembly having a number of channels through which hot and cold water flows to and from the valves. Each of the valves communicates with an orifice, with each orifice communicating with the hot water valves being of a different size to produce binary flow patterns of water exiting the hot water associated orifices and valves. Similarly, each of the orifices communicating with a cold water valve is of a different size so that the flow rate of water from each cold water associated orifice is related in a binary manner to the flow rates through the other cold water associated orifices and valves. Because of the greater viscosity of the hot water, it is preferable that the hot water associated orifices be of a smaller size than corresponding cold water orifices. The opening/closing of the valves is controlled using information stored in memory. The programmed information correlates valve openings with information relating to water temperature. When there is a difference between actual and desired temperatures, one or more different combinations of valves can be opened in a predetermined manner without cycling through all possible valve combinations defined between the current combination of valve openings and the next combination of valve openings whereby the difference between the actual and desired temperatures is rapidly reduced.

Method and apparatus for controlling the temperature of a liquid

A remote controller is disclosed for controlling the throttle, brake and steering mechanism of a conventional motor vehicle, with the remote controller being particularly advantageous for use by severely handicapped individuals. The controller includes a remote manipulator which controls a plurality of actuators through interfacing electronics. The remote manipulator is a two-axis joystick which controls a pair of linear actuators and a rotary actuator, with the actuators being powered by electric motors to effect throttle, brake and steering control of a motor vehicle adapted to include the controller. The controller enables the driver to control the adapted vehicle from anywhere in the vehicle with one hand with minimal control force and range of motion. In addition, even though a conventional vehicle is adapted for use with the remote controller, the vehicle may still be operated in the normal manner.

Remote control for motor vehicle

A novel mechanical power coupling means employed with a novel material compacting apparatus and utilizing either reciprocal or continuous drive inputs with the coupling means. In the preferred compacting apparatus embodiment a reciprocal drive is used such that the compactor is powered by both reciprocating movements of the input shaft. The compactor may be driven in a variety of speed/torque arrangements using the novel coupling means. The coupling means includes a wrapped spring clutch which automatically engages the highest speed mechanical arrangement capable of overcoming the load on the output shaft.
