Abstract: A mnotorized flow valve and electronic controller is mounted to a flowmeter (1) having a sensor (3) creating a flow-related signal. The valve (11) includes a tapered valve stem (52) linearly moving through a round sharp-edge opening (53) in an orifice plate (43) to establish a precise flow rate at high pressures as in a treating furnace. The stem (52) is longer than the opening (53). A stepping motor (26) has a linear moving shaft (57) connected to the valve stem (52). A knob (27) on the shaft (57) permits manual valve setting, and interlocks to fix the shaft (57) against rotation for motor positioning. The stem (52) and shaft (57) are releasibly coupled for use of different stems in one orifice plate (43), which is also replaceable. An electronic controller (6) provides compensation for non-linearity in flow rate. A relatively constant force relationship on the stem (52) is established, with the valve (11) totally closed with a small seating force and with a relative low breakaway force. The controller (6) actuates the motor (26) through a special multiboard circuit to a demand flow. A manual control is enable if the programmed circuit malfunctions. A motor speed change circuit responds to a differential in the level of the sensed and demand signals. Limit signals set the manual control. A control panel (30) includes an auto/manual switch (31), a manual control switch (32) and lamps (36, 37) which indicate the state of the valve control malfunction thereof.

Abstract: A shaft angle encoder is provided with a symme­trical code wheel and pattern of photodetectors for providing an index pulse indicative of shaft angular position. The code wheel has two concentric index tracks each of which is symmetrical in a circumferential direction and are symmetrical with respect to each other and also with respect to a data track for indicating increments of angular position. In an exemplary embodiment there is a pair of windows of unit width in the one index track with a spoke therebetween with a width of at least two units. A pair of lateral windows extend away from each other more than a unit width along the second track. An opaque area at least two units wide is provided between the lateral windows in the second track. The photodetectors are arranged so that when the code wheel is in the index pulse position, a pair of photodetectors for the inner track are illuminated through the windows in the inner track, and two photodetectors for the outer track are both occulted by the opaque area between the lateral windows in the second track. Such an arrangement provides symmetry of the code wheel so that it can be inverted either accidentally or intentionally during assembly and yet side lobes of photocurrent from the photodetectors on the separate tracks are not coincident, thereby avoiding false index pulse triggers.

Abstract: A method for balancing the loads on channel paths in a digital computer during long running applications is disclosed. Only the load associated with relatively long running applications is monitored. For each volume of data eligible for processing, the selection of volumes is first made from those having affinity to the calling host. The load across the respective connected channel paths is calculated. The calculation is weighted to account for the different magnitudes of load resulting from different applications and to prefer the selection of volumes connected to the fewest unused channel paths such that processing of the selected volume will maintain the maximum number of unused channel paths. The optimal volume is selected as the next volume to be processed. The monitored load on each channel path is then updated to include the load associated with the newly selected volume, assuming that the load associated with processing the volume is distributed evenly across the respective connected channel paths. The selection of the following volume is then based on the updated load information and the method continues cyclically during subsequent selection of the remaining volumes for processing.

Abstract: A fluid-powered servo actuator having a body, an annular piston, and a shaft extending co-axially therewithin. The shaft has an interior chamber located within the body with two fluid channels extending to the chamber in which the piston is mounted. One channel communicates with each side of the piston. A valve spool is positioned in the shaft chamber, and a cam follower or threads are used to longitudinally move the valve spool therewithin in response to its selected rotation. The valve spool has a pair of valve lands which, when in a neutral position, close the two channels. When the valve spool is moved longitudinally, pressurized fluid is communicated with one or the other of the channels to cause the piston to move longitudinally. Splines or rollers convert the longitudinal movement of the piston into rotational movement of the shaft. The cam follower or threads cause the resulting rotational movement of the shaft to move the valve spool back to the neutral position when the shaft has rotated by an amount and in a direction corresponding to the selected amount and direction the valve spool was rotated.

Abstract: In a speech parameter encoding method of encoding an input speech signal into a sequence of encoded signals, vector quantization is carried out through a plurality of vector quantizers which are connected in cascade to one another through subtractors and which cooperate with code books, respectively. Such a cascade connection of the vector quantizers may be supplied with the input speech signal either at every frame or at every subframe shorter than the frame to produce a set of code vector candidates from each of the vector quantizers. Each set of the code vector candidates is sent to a cumulative distortion calculator to select an optimum combination of the code vector candidates and to produce, as the encoded signals, an index representative of the optimum combination. Alternatively, a sequence of coefficients which represent a spectrum parameter is calculated at every frame and is divided into a plurality of coefficient groups each of which is subjected to vector quantization to produce a plurality of code vector candidates for each coefficient group. Cumulative distortions are calculated for combinations of the code vector candidates to select an optimum combination.
