Abstract: ABSTRACT OF THE DISCLOSURE HEADING REFERENCE AND LAND NAVIGATION SYSTEM A heading reference system for sensing vehicle heading relative to fixed inertial space is mountable in a vehicle such as a land-based vehicle and includes a two-degree-of-freedom (TDF) dynamically tuned gyroscope responsive to vehicle rotation about pitch and yaw axes for generating rate signals indicative of the rotation.  A caging loop generates force signals for torquing the gyroscope to a null position.  A pair of accelerometers are responsive to misalignment of the vehicle relative to a horizontal plane formed by the pitch and roll axes.  Processor circuitry is responsive to the force signals, the misalignment of the vehicle relative to pitch and roll axes, and distance signals generated by an odometer unit to apply heading signals to an indicator unit for visually indicating to a vehicle operator the directional heading.

Abstract: ABSTRACT OF THE DISCLOSURE          FOCUSING CONTROL CIRCUITRY FOR AN OPTICAL MEMORY SYSTEM        An optical storage system employing a lasesr beam which is directed and focused onto an optical disk for reading and/or writing data in a track of the disk.  Proper focusing is maintained using focusing control circuitry which produces a focus error signal that is applied to a focus motor.  This focusing control circuitry is able to return the objective lens assembly to its in-focus position so long as the objective lens assembly remains within a predetermined capture range.  In the event that the objective lens assembly is outside of this capture range, a waveform generator is enabled which produces a correction signal that causes the focus motor to move the objective lens assembly back within the capture range with a velocity and for a time period sufficient to permit the focusing control circuitry to regain control and return the objective lens assembly to its in-focus position.

Abstract: A TIME SHARED CONFERENCE ARRANGEMENT      ABSTRACT OF THE DISCLOSURE The conference circuit provides for estab-lishing a conference call between three conferees in a T-S-T digital switching network.  The voice samples of the three conferees are sequentially stored in input buffers.  When all three conferees' samples are stored, the samples are transferred to working buffers, while the input buffers store three other conferees' samples.  In the time slot succeeding the transfer to the working buffers, two conferees' voice samples are compared.  During the next time slot, the resultant of the comparison is transmitted to the third conferee.  This conference arrangement provides for time sharing up to 64 three-port con-ference calls via the switching network.

Abstract: OIL RECOVERY METHOD             ABSTRACT OF THE DISCLOSURE          Oil is recovered from an oil-bearing reservoir in a process employing an in-situ combustion process utilizing a combustion-supporting gas containing at least 75% by volume pure oxygen, and preferably substantially pure oxygen, and a sequence in which the production well or wells are cyclically throttled.  In place of using an in-situ combustion process, mixtures of steam and carbon dioxide or mixtures of steam and low molecular weight C3-C8 hydrocarbons are injected into the reservoir and the production well is cyclically throttled.  The production well flow rate is restricted until the bottom-hole pressure of the well has increased to an amount of about 30% to about 90% of the fluid injection pressure at the injection well.  Thereafter, the production well is opened and oil is recovered therefrom as the bottom-hole pressure declines.  The throttled production cycle may be repeated at appropriate intervals during the process.

When the lock arrangement is formed, the primary locking tab is locked' behind a shoulder on the inner closure panel defined by the displace-ment of the secondary flap and the primary locking tab extends through the aperture and is locked behind the locking ear.  The primary locking tabs and the secondary tabs are disposed in side by . side relation with the secondary locking tab project-ing generally normal to the closure panels and projecting between adjacent containers so as to hold the containers apart.  The secondary flap is of a width at least equal to the overall width of the primary lock arrangement.

Abstract: ANCHORING ARRANGEMENT FOR FREELY OSCILLATING STEEL TENSION  ELEMENTS OF A DYNAMICALLY STRESSED STRUCTURAL COMPONENT                               ABSTRACT        The tension elements of a steel tension member are anchored at their ends by means of wedge clamps in an anchor body, through the bores of which, running parallel to one another, they are led.  The diameter of one end section of each bore is constant and larger than that of the ten-sion elements.  For the purpose of taking up deflecting forces, there is provided in the deflection zone of the anchor body a resiliently yielding ring which is accommodated in a circular recess in the wall of the exit end of each bore.  In the deflection zone of a spreader ring, where the tension elements converge to form a bunch, there is provided an insert of material softer than that of the spreader ring or the tension elements. The material of the resiliently yielding ring is likewise softer than that of the anchor body or the tension elements.  With this anchoring ar-rangement, the deflecting forces acting upon the tension elements are eliminated at both the first and the second deflection locations.
