Abstract: FREQUENCY RESPONSIVE SWITCHING CIRCUIT               ABSTRACT OF THE DISCLOSURE       A frequency responsing switching circuit that, in the preferred form, includes circuit means for generating a periodic first electrical signal.  The first electrical signal is applied to a retriggerable monostable multivi-brator having as its output a second electrical signal.          A timing circuit associated with the retriggerable monostable  multivibrator controls  the duration of the output pulses constituting the second electrical signal.   If the period of the first electrical signal is less than a predetermined amount, the second electrical signal is maintained at a fixed voltage level due to continuous retriggering of the multivibrator.  The second electrical signal is applied to the data input of a shift register and the first electrical signal is supplied to the shift register as a trigger input.  Multiple bit outputs of the shift register form the inputs to a gate circuit.  If the second electrical signal is maintained at the fixed voltage level for a plurality of periods of the first electrical signal, then the gate circuit produces an output signal indicative of this circumstance.  Thus, if the period of the first electrical signal, for a plurality of its cycles, is below a predetermined amount of time, an output signal is produced.

Abstract: ABSTRACT OF THE DISCLOSURE             A device for scanning adjacent profiles in stereo-photographs is particularly used in differential rectification operations including automatical image correlators.  Such a device permits when dynamically operated a high scanning speed due to the flying spot raster control employed for scanning.          The control is effected by a d.c. tachometer which, connected to a servo-motor for performing advance operations, supplies signals proportional to the scanning direction and scanning speed. Said signal is superimposed to the voltage which deflects the raster generating cathode rays so that one is capable of additionally deflecting the raster in advance direction.  The raster control permits an on-line dynamic operation between a differential rectifier and a stereo plotter.

Abstract: ABSTRACT OF THE DISCLOSURE A simplified method for the fabrication of a fire-place water jacket, and the water jacket produced by the fabrication method.  Each of several walls of a water jacket is formed from first and second metal plates.  The first metal plate of each wall is disposed in a generally horizontal position on an orificed support, and a punch is brought into operative engagement therewith to punch a hole in the plate and simul-taneously deform the area surrounding the hole so that the plane of the hole is spaced a given distance as from the plane of the plate.  The first plate is then placed on the second plate so that the plates are generally parallel and so that the area surrounding the hole in the first plate abuts the second plate, and then the plates are secured together by welding around the area defining the hole in the first plate to the portion of the second plate visible through the hole in the first plate.  The plates when joined together are spaced apart a distance S and water may circulate between the plates.  The various walls are joined together to form a water jacket having an inlet and an outlet, and preferably at least three walls are provided including two sides and a back wall.  The bottom of the water jacket may be formed by a header extending between the two side walls and a plurality of water-conducting, log supporting pipes extending generally perpendicular to the header from the header to the back wall of the water jacket.  The pipes are disposed at a small positive angle (1 to 2°) with respect to the horizontal.

Abstract: 1022.005 GKP     S P E C I F I C A T I O N            READILY INSTALLED FOOD PROCESSOR CUTTER TOOL WITH NEGATIVE                      BLADE LIFT     Inventor: Carl G. Sontheimer ABSTRACT OF THE DISCLOSURE     In order to overcome the unexpected dynamic lifting action of an easily installed rotary cutter tool in a food processor-as the lower blade revolves at relatively high velocity through food material, such as shelled nuts in making nut butter, a downward inclination in a forward direction is provided in at least the lower blade, near its outer tip.   If desired, such an inclination may be in-corporated into both blades of the cutter tool.   This downward inclination of the blade surface to provide a negative angle of attack (-A) relative to the direction of rotation may be accomplished in a preferred embodiment by twisting the outer blade portion into a negative angle of attack relative to the remainder of the blade or by mounting the whole blade onto the hub at a negative angle of attack. Thus, as the lower blade moves at relatively high velocity through food material, there is a continuous impact of the food material against the downwardly inclined blade surface at least near the tip region producing a downward component of thrust for holding the tool hub down firmly seated in its proper relationship upon the rotating drive shaft.

Abstract: ABSTRACT OF THE DISCLOSURE      The servomotor outputs of two substantially identical servo channels, are connected through a differential mechanism to position an attitude control surface of an aircraft in response to common or separate, normally identical, command signals applied to the respective channels.  Position and rate feedback means responsive to the movement of the control surface and each servomotor provides position and rate feedback signals to their respective channels.  The primary position rate feedback term for each servomotor channel is derived from the position feedback means rather than from a servo tachometer to increase the stiffness of the output in resisting the motions commanded by a failed servo channel and to improve fault detection capability by increasing the difference velocity between a good and a failed channel. Improved electrical equalization means, to allow more effective or lower velocity mismatch between the two servo channel motors, is provided wherein the equalization includes limits, which are varied in response to the input command.  Also, monitoring with fault isolation is provided employing an estimate of surface position whereby the system is provided with fail operational characteristics.

Abstract: 28.3.79                  1                      PHN 9079 ABSTRACT: System for transmitting binary data via a number of channels.           In a system for introducing binary data elements into or for extracting these elements from a medium, the medium comprises a number of data channels in which each time a group of data bits are introduced together, i.e. one per data channel. During the intro-duction, the data bits are also applied to a coding de-vice. In synchronism with the introduction of such a group of data bits, this coding device each time forms a first correction bit for a first correction channel and a second correction bit for a second correction channel. The first correction bit is formed on the basis of a second group of data bits, the second correction bits being formed on the basis of a third group of data bits. Each data channel supplies the data of two sub-groups of data bits for this purpose. When the delay operator having a length of one  bit cell  is represented by D, a series of directly successive bits can be re-presented by a polynomial in D: xO.DO + x1.D1 + x2.D2 + ..., in which xj (j = 0,1 ...) represents the bit value. The quotient of the polynominals relating to the two sub-groups of a data channel is different for each data channel in order to enable correction of an arbitrary error pattern in a single data channel. When the data bits and correction bits are extracted from the medium, each time a first and a second error elimination bit are 28.3.79                   2                   PHN 9079 calculated from the extracted data bits by using the same algorithm, i.e. the same configurations of the sub-groups. Comparison of first/second correction/elimination bit each time produces two error detection bits. When a given num-ber of successive error detection bits do not indicate a discrepancy, the passage through the medium is error-free. When a given configuration of discrepancies is detected, a correction vector is formed which indicates, after storage, the channel containing an error, whilst further error detection bits indicate the error pattern which can thus be corrected.

Abstract: ABSTRACT An ultrasonic level measuring system is disclosed for determining by a time-ratioing technique the level of a liquid within a storage tank.  An instrument sensor assembly, including a waveguide formed of a tensioned, ferromagnetic wire having a low thermoplastic coefficient is vertically sup-ported within a storage tank containing a liquid.  The waveguide is positioned to span both the tank liquid and vapor spaced.  Two permanent magnets are positioned in close proximity to the waveguide at a known dimensional separat-ion which defines the calibration span of the system.  The waveguide and magnets are housed in a protective shield which acts as a process barrier and which is convoluted over a substantial portion of its length allowing the instrument sensor assembly to be easily transported and installed.  A float housing a permanent magnet is positioned concentrically about the instrument sensor assembly to rise and fall with the liquid level.  An ultrasonic trans-ducer is formed of a field coil wrapped about a section of permanently magnet-ized, magnetostrictive wire.  The magnetostrictive wire is butt welded to the top end of the waveguide.  The field coil is excited by a current pulse intro-ducing a torsional ultrasonic pulse into the waveguide.  As the ultrasonic pulse passes each of the three magnets (i.e., the top, float and bottom mag-nets), a low level voltage pulse is generated across the waveguide.  The voltage pulses are detected and amplified by sensing circuitry and coupled to a signal processing unit.  The processing unit produces an output signal indicative of the liquid level by ratioing the time interval between the float and bottom magnets to the time interval between the top and bottom magnets.          The resulting ratio is scaled by being multiplied by the known distance between the top and bottom magnets, (i.e., the system span) to produce a measure of the liquid level in the tank.
