Abstract: A plurality of spray nozzles are utilized to introduce a fluid into a vessel. Control valves are associated with each one of the plurality of spray nozzles. The control valves are either fully closed or fully open. The actual value of a process variable is compared to the desired value of the process variable to generate a difference signal. Control signals are generated in response to the difference signal. Different combinations of the control valves are opened in response to the control signals so as to provide a fluid flow rate which will maintain the actual value of the process variable substantially equal to the desired value. The on-off nature of the control valves provides a substantially maximum pressure drop across the spray nozzles when fluid is flowing through the spray nozzles.

Abstract: The invention relates to a coin validator for use in a micro-processor controlled call coin box telephone instrument. The validator comprises first and second coil sets driven by square wave interrogation pulses. The arrangement of the coils is such that when a coin is in the coin-runway of the call coin box, one coil pair is used to interrogate the coin in the runway while the other coil pair provides environmental conditions apertaining to the runway. The information generated by both coil sets is combined thereby compensating for environmental changes and drift. Information pertaining to the relative response times of the secondary coils is then used to determine coin validity.

Abstract: knee brace comprises generally U-shaped upper and lower support members (12, 14) for fitting around the upper and lower leg above and below the knee joint, two pairs of upper and lower support arms (16, 18, 20, 22) extending downwardly, respectively, from the upper and lower support members (12, 14) along opposite sides of the patient's upper leg, and polycentric hinges for pivoting the upper support arms (16, 18) to the lower support arms (20, 22) adjacent lateral and medial sides of the knee joint. Floating condyle bads (52, 54) are affixed to fixed inside portions of the polycentric hinges. The condyle pads (52, 54) are held in direct contact with the lateral and medial sides of the patient's knee joint. The condyle pads (52, 54) are restrained from rotational movement but are hinged so they can pivot toward or away from each other about common generally vertical axes within the space between the polycentric hinges (64, 66). The condyle pads can be spring-biased inwardly by their hinges for contact with opposite sides of the knee joint during swinging movement of the upper and lower leg about a horizontal axis. Flexible and longitudinally elastic upper and lower straps (96, 98) are releasably secured to the upper and lower limb support members. The straps extend in opposite directions away from the sides of the upper and lower support members. This provides a de- rotation strapping system which inhibits twisting of the lower leg relative to the upper leg about a vertical axis.

Abstract: An electronic controller having a detachably mounted front panel unit on which display devices and control elements are arranged is disclosed. By means of the control elements, the process variables and the control parameters are changed incrementally. Values of the control parameter, process variables, and the selected control parameter are indicated by the display devices. To provide a compact, independent front panel unit which can be removed from the main housing of the controller for protection against unauthorized operation, the front panel unit is provided with a slave microprocessor which is connected via a plug-in connector to a master microprocessor in the main housing. Because the master microprocessor operates independently of the front panel mounted slave microprocessor, the front panel unit can be removed without affecting the operation of the controller.
