Abstract: DIGITAL FLUID FLOW RATE SENSOR                      ABSTRACT      A flow rate sensor includes a diaphragm operated switch coupled to a Venturi in a flow conduit.  The appara-tus includes a housing having a diaphragm defining a cham-ber.  The chamber has a first port connected to the Venturi and a second vent port.  A valve connected between the first port and the diaphragm is spring loaded so that the first port is normally open.  In the absence of fluid flow, the Venturi pressure is zero under the diaphragm and the dia-phragm is at rest in an up position so that the valve is open.  With fluid flow through the Venturi, vacuum will build under the diaphragm so that the diaphragm will tra-vel down until the valve closes the first port.  With the valve closed, pressure under the diaphragm will increase due to flow through the vent port and the diaphragm will move up.  The valve will remain closed until the diaphragm up stroke is equal to the valve stem lost motion.  The valve will then open and the process will cycle so that the diaphragm oscillates at a rate that bears a relation-ship to the square of the fluid flow rate through the Venturi.  A sensor coupled to the diaphragm produces a pul-sating digital signal, from which signal the flow rate may be calculated.

Abstract: Abstract In the multi-layer welding of a joint of two pieces of metal to be welded by arc welding, the proper number of passes and the desired tracing positions of a welding torch for each layer are automatically established during the welding of the preceding layer.  The welding torch is subjected to a Y-axis control so as to maintain constant the arc voltage or current during the welding and simultaneously the torch is caused to weave in the direction of an X-axis within the groove.  The tracing of the groove by the torch is accomplished by controlling the weaving turning positions of the torch in accordance with the X-axis and Y-axis direction displacement data of the torch and the torch displacements in the X-axis direction are compared with a predetermined value thereby determining the proper number of passes to be made in the welding of the next layer.

Abstract: ABSTRACT   An improved rotating disc wood chip refiner would provide the required pulsating cavitation regime , but would use less than 50% of the energy consumed by usual rotating disc wood chip refiners with square, sharp-edged radial bar/slot profiles, due to 3 minimum energy conditions.  First, a resonating cavity model of wood refining is tuned for least energy and agrees with Atack's classic obser-vations of wood fibers (1).  Second, a low fluid-dynamic drag radial bar profile would require less than 50% of the usual square bar-drag energy, see Hoerner (2).  Third, a pressure  recovery radial slot profile would require less than 50% of the usual square slot drag energy, see Adkins(3).          References 1.

Abstract: Abstract of the Disclosure Signals from redundant sensors located throughout a pressurized water reactor (PWR) nuclear power plant are processed in four independent channel  sets each of which includes  a  plurality  of  independent  microcomputers which calibrate,  convert  to  engineering  units  and  calculate partial  trip  signals  and  engineered  safeguard  actuation signals from the sensor signals for use in the conventional voting logic of a plant protection system. The primary and secondary partial  trip and engineered safeguard actuation functions associated with various postulated abnormal events are allocated to different independent microcomputers in the channel  set  for  reliability.  A  test  unit  common  to  the channel set automatically, rapidly bypasses and tests each protection function independently while the other protection functions  in  the  channel  set  remain  on-line  and  also continually tests each microcomputer through a dummy test function  performed  along  with  the  assigned  protection functions. Signals representative of the analog value of the sensor  signals  are  stored  by  the microcomputers and are transmitted by a serial data link through a common elec-trical isolation unit to a common analog output device for use by the plant control and monitoring systems under the control of a communication processor common to a group of microcomputers in the channel set.

Abstract: ABSTRACT                    DATA COMPRESSION     An adaptive system for binary data compression incorporating a coding scheme which is simple to implement, which limits codeword length and which can be implemented by software.   Data compression is achieved by assigning four bit codes to the eight most frequently occurring characters in the data and eight or nine bit codes to the remaining characters wherein the code assignment is made according to a continuously updated evaluation of character frequency distribution.  Run length encoding may be used in conjunction with this technique, to achieve further data compression.   For transmission, error control protocols are applied to the compressed data where such protocols may include the use of forward error correcting (FEC) coding and an automatic repeat request (ARQ) system.  The data may be transmitted using a burst error control system based on interleaving so that a single error correcting FEC coding can correct bursts of errors characteristic of a telephone system.
