Abstract: TITLE   An Electrical Timing Control Switch.                         ABSTRACT    An  electrical timing  circuit  for  controlling  the activation  and  deactivation  of  an  electrical  load  by setting a predetermined time period for which the load will be on and for providing one or more short warning periods wherein  the  load  is  deactivated  prior to  the expiration of the predetermined time period.    The in-vention may be used as a switch for a light whereby the light may be actuated to remain on for an hour,  but just prior to  the expiration of hour period the light will momentarily go off for one or more warning periods prior to the  light being turned completely off  so that  the switch may be reaetuated to start another timing period.          Momentary switches (12) control a set-reset circuit (16) which sends a signal to a NAND gate  (18).    A timing circuit (20) is responsive to the momentary switches (12) to provide a plurality of time spaced-signals.    A first gate means  (22) responds to the timing circuit  (20)  to provide an input to the summing gate (18)  to effectively turn the load off,  but only for short warning periods.  A second gate means  (24)  is responsive to both the first gate means (22) and the timing circuit (20) to provide an input to the set-reset circuit  (16)  to effectively turn the load off at the end of the predetermined period.

Abstract: Abstract of the Disclosure An image distortion correction method and appar-atus is disclosed. An electron beam generated in a Cathode-Ray-Tube (CRT) sweeps horizontally. Simultan-eously therewith, the intensity thereof varies in ac-cordance with an incoming video signal representative of video information. As a result thereof, the video information is transferred to a display of the CRT. Various types of video image distortion appears on the CRT. To compensate for this distortion, the rate at which the video information is transferred to the dis-play of the CRT is varied in accordance with the posi-tion of the electron beam during the sweep thereof. Since the video image distortion is a function of the position of the electron beam during the sweep there-of, in accordance with this invention, said rate at which the video information is transferred to the dis-play of the CRT is varied in accordance with the par-ticular distortion being compensated therefor.

Abstract: ABSTRACT OF THE INVENTION         A circuit having a nonlinear response characteristic provides gamma compensation to a video luminance signal and matches any desired output response curve by selecting the number of diodes connected as series connected circuits in the compensation circuit.  The relationship among the various numbers of series-connected diodes is dependent upon having a current flowing into an output circuit which is the same as a current flowing out of a collector circuit of a differential amplifier, to which the input video luminance signal is applied, and through series-connected diode circuit. These currents are maintained equal by use of a current-mirror circuit, which provides an input current to an output transistor that has in its emitter circuit one of the series-connected diode circuits, and the compensated luminance signal flows in the collector circuit thereof.  The differential amplifier is stabilized and balanced by a difference amplifier connected in feedback across the collector leads of the differential amplifier in conjunction with a pedestal clamping synchronization signal and a capacitor to provide a balancing signal at the base lead of the second transistor of the differential transistor amplifier.

Abstract: Abstract:    A process for upgrading low quality, highly oxidized coals to make them more suitable for carbonization, combination or liquefaction.  The process comprises reducing (e.g. grinding) the coal to a particle size of 60 mesh (about 250µ ) or less, feeding the resulting pulverized coal to a reactor, contacting the coal with water or steam and with carbon monoxide or synthesis gas (CO + H2), heating the reactor contents to bring about upgrading and then cooling the reactor and removing the coal.  The reaction temperature must be about 50°C + 5°C below the softening temperature of the coal as measured by a Ruhr dilatometer and the reaction should be allowed to proceed at that temperature for 45-55 minutes.  The initial gas pressure should be 1500 + 100 psi (10.3 + 0.7 MPa) at 25°C.  Finally, the amount of water or steam relative to the coal should be at least 0.2:1 by weight. When these reaction conditions are followed, a coal having significantly improved combustion, coking or liquefaction properties can be obtained.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved apparatus for conveying a strip of raw material for producing bags in a bag producing machine is disclosed which includes continuously operating conveyors, a inclined belt conveyor and intermittently operating conveyors.  The inclined belt conveyor is disposed at the intermediate position between the upstream and downstream conveyors so as to displaceably hold the loosened part of the material strip on the inclined upper surface and includes an endless belt made of air permeable material such as cloth, net or the like.  A suction device is arranged just beneath the endless belt of the inclined belt conveyor to suck air through the air permeable belt so that the strip is attracted toward the upper working surface of the inclined belt conveyor.  To assure that the strip is delivered to the processing section in the bag producing machine, a horizontally extending guide roller is disposed above the inclined belt conveyer in the proximity of the latter at the working area extending between the middle part and the upstream end part of the inclined belt conveyor.

Abstract: INTERNALLY DRIVEN EARTH ANCHOR HAVING SMALL DIAMETER ANCHOR ROD     Abstract of the Disclosure An improved modular screw anchor is pro-vided which is adaptable for use with many sizes of elongated anchor rods, is inexpensive to manufacture, can be installed in a wide variety of soil conditions including rocky soils, and permits use of a number of wrench tubes having different  internal dimensions.          The anchor preferably includes two main components, namely an elongated anchor rod having an obliquely oriented, beveled earth-penetrating lead at one end, and a polygonal in cross-section drive boss separated from the lead by an enlarged, annular flange, and, secondly, an anchor member having a bore-defining hub, an outwardly extending, helical blade circumfer-entially secured to the hub, and an apertured plate affixed across the bore of the hub. The anchor rod and anchor member are interfitted for installation by inserting the rod through the apertured plate of the hub until the drive boss extends through the aperture and the flange abuts the apertured plate.  A polygon-al in cross-section tubular anchor wrench is then telescoped over the rod and inserted into the hub bore;  the wrench tube is complementally configured for establishing a driving engagement between the outer faces of the wrench and the hub, and between the inner faces of the wrench and the drive boss. Axial rotation of the wrench thus effects rotation of the anchor for installation.  The engagement of the flange to the apertured plate is particularly advan-tageous because this arrangement allows the lead, flange, and drive boss to be dimensioned for use with a smaller diameter rod.
