Abstract: OVERLOAD DEVICE FOR GAS TURBINE ENGINES     A B S T R A C T         An overload device in an output gear box of a high speed turbine engine protects the output gears and shaft system of the turbine against damage due to instantaneous high loads imposed on the turbine as, for example, high loads due to out-of-phase paralleling of a generator.  The device comprises interleaved friction discs normally compressed together under a predetermined load by a plurality of spring-biased clamping bars.  When the torque load on the friction discs exceeds a predetermined amount, the discs will slip whereby the torque overload is alleviated.

Abstract: "FOLDING BOX FOR CONTAINING AND DISPLAYING ARTICLES          SUCH AS FRUITS AND VEGETABLES"     Abstract of the Disclosure Bottom parts,overlapping on a longitudinal median strip  and connected at bending lines with the long sidewalls of a folding box, are attached to the short sidewalls by connection flaps which have triangular ears glued to the adjacent short sidewall halves.  The triangular adhering ears are bounded by 45° fold lines from the remainder of the connecting flap.  The lower bottom part has a shallow oblique cutout at each end with its apex on the folding line between it and the connecting flap, so that the upper bottom part will ride on it easily as the box is set up while blunt corners on the leading edge of the oblique cut-out press in to provide snap action as the box is set up by inward pressure on the short sidewalls.  In the folded condition, the sidewalls are folded together along the midline of the narrow walls.  The two bottom parts are fastened together by a sticking strip edge along the middle.  The lower bottom part bends on a folding line at the edge of this strip as the box is set up.

Title: Apparatus for recording and reproducing video signals  on a magnetic tape movable at different speeds

Abstract: ABSTRACT OF THE INVENTION             In apparatus for recording and reproducing video signals in successive parallel tracks on a magnetic tape by means of magnetic beads or transducers repeatedly traversing the tape at a steady rate while the tape is driven longitudinally, and in which at least a portion of the video signals, for example, the luminance component of color video signals, frequency modulates a carrier to provide frequency modulated signals applied to the beads for recording in the tracks; the speed at which the type is driven is reduced from a normal value to a relatively slow speed for eliminating guard bands between the tracks and reducing the widths of the latter so as to achieve a high recording density on the tape, and the frequency deviation of the frequency modulated signals applied to the heads is relatively reduced  when the tape is driven at such slow speed during recording for minimizing the interfering signal due to cross-talk that occurs upon reproducing of the signals recorded in the tracks of reduced width without guard bands therebetween.

Title: Telephone system for automatic redialing of  busy numbers
Inventor: SUTTON PAUL J
IPC: H04M1/30
Filed: 1977-08-29
Granted: 1980-07-22
Abstract: ABSTRACT OF THE DISCLOSURE         A telephone set which will automatically redial a telephone number after a busy signal has been received and continues redialing that number until the party being called answers, or until a predetermined number of attempts have been made.  As the user dials a telephone number onto the telephone line, whether by manual dialing or by utilizing pulse-type dialing of "touch-tone" type, the number  is simultaneously stored in a storing device.  A signal detector detects the receiving of a busy signal in response to the dialing of the telephone number.  A control circuit, responsive to both the detection of a busy signal and the releasing of the telephone line, waits a predetermined fixed amount of time subsequent to which it seizes the line and causes the number  stored to be redialed onto the telephone line. If a busy signal again occurs, a line disconnect circuit responds by releasing the line.  The routine is repeated for a predetermined number of times or until a normal ringing signal is obtained, and thereafter the control circuit and the storing means are reset.

Abstract: FUEL METERING AND DISTRIBUTION                 Abstract of the Disclosure A combustible air-liquid fuel mixture having a substan-tially constant air-to-fuel ratio is produced for delivery to the intake manifold of an engine.  Air is passed through a fluid flow device having a variable area throat zone to increase the velocity of the air to sonic, and the area of the throat zone is varied in correlation with operating demands imposed upon the engine for which the mixture is produced.  Liquid fuel is metered from a sup-ply and distributed into the air stream at or before the throat zone in direct proportion to the cross-sectional area of the throat zone.  Due to the particular design of the fluid flow device, air at sonic velocity passes through the throat zone over substantially the entire operating range of the engine down to low manifold vacuum levels.  A fuel bar in the form of a rod meters and dis-tributes the liquid fuel into the air stream.  The rod has spaced apart tapered slots and the fuel flows along these slots and is stripped away by the rapidly moving air stream.

Abstract: ABSTRACT         A stress relief device for a flexible shaft used to connect a rotary drive to a rotary load, wherein the shaft flexes in response to loads that produce bending stresses during shaft rotation.  The shaft has a radial flange, or hub, on at least one end for connecting the respective end to another rad-ial flange on either the rotary drive or the rotary load.  In order to relieve the joint between the shaft and the hub from the stress concentration that occurs due to flexure of the shaft while being supported as a cantilever beam, an annular stress relief member is mounted on the shaft inwardly of and tightly secured to the radial flange, or hub.  The specially designed stress relief member is tightly positioned around the underlying cylindrical surface portion of the shaft to provide a fixed-end cantilever-type support therefor so that beading stresses occurring due to shaft flexure are more gradually transmitted to and through the stress relief member to avoid stress concentration at the junction of the shaft and the radial flange, or hub.
