Abstract: Abstract of the Disclosure An improved process and apparatus for recovering hydro-carbons from an air-hydrocarbon vapor mixture such as the mixture of air and vaporized light hydrocarbon compounds expelled as a result of loading gasoline or the like into storage tanks and tank trucks.  The air-hydrocarbon vapor mixture is caused to flow through a bed of solid adsorbent so that the hydrocarbons are removed from the mixture and a residue gas stream comprised of substantially hydrocarbon-free air is produced.  The substan-tially hydrocarbon-free air is vented to the atmosphere and a second bed of solid absorbent having hydrocarbons adsorbed there-on is subjected to conditions which cause desorption of the hydrocarbons and thereby regeneration of the bed.  The flow pat-tern of the inlet air-hydrocarbon vapor mixture and the bed of solid adsorbent being regenerated are periodically changed so that when the bed through which the inlet air-hydrocarbon mix-ture is flowing becomes loaded with adsorbed hydrocarbons, the inlet air-hydrocarbon mixture is caused to flow through the bed which has just been regenerated.  The regeneration of the beds is accomplished by evacuating the beds with vacuum pumping so that a major portion of the hydrocarbons are desorbed there-from and subsequently introducing a small quantity of heated hydrocarbon-free air into the beds so that additional hydrocar-bons are stripped therefrom.  The air-hydrocarbon vapor mixture produced in the regeneration of the beds is contacted with a heated first portion and a second portion of a liquid absorbent so that a major portion of the hydrocarbons are absorbed therefrom and recovered.  The first portion is heated by passing it in heat exchange relationship with a seal liquid used in a vacuum pump which effects the vacuum pumping of the adsorbent beds.          Apparatus for carrying out the process of the invention is also provided.

Abstract: ABSTRACT Ink jet and xerographic binary graphic printers are disclosed which make reproductions by marking the pixels within a raster pattern on a copy sheet with a high or low density (e.g. black or white) mark in response to electrical printing signals. The printing signals are generated by comparing the magnitude of video signals representative of a continuous tone raster image with electrical screen signals organized into halftone cells according to a pattern. A shift circuit processes received video signals and identifies the center of the black (or white) video signals within the confines of a screen halftone cell. The pattern of screen signals within a halftone cell is shifted to the center of the black video signals. The cell shifting suppresses beat frequencies in reproductions of originals containing screens or image detail with frequencies near that of the electrical screen.

Abstract: ABSTRACT A method and apparatus for controlling an AC induction motor, having at least two phases. The motor is controlled in a known manner by two input signals S1, S2, which are connected to a resolver (1), the output signals of which are used to generate separate supply signals to the  motor phases. A measured signal U, representing the rotational speed of the motor, is fed back to the control system and is used for calculating the oscillator frequency of the oscillator (5), which drives the resolver.    A calculating circuit calculates the oscillator frequency as the sum of the first control signal S1 multiplied by a first constant factor, and the tachometer signal U multiplied by a second constant factor.    As a result of this control method the oscillator frequency will in-crease with increasing control signal S1 and increasing tachometer signal U, but decrease with increasing motor load, because the motor speed will de-crease. This automatic frequency adjustment results in constant amplitude of the stator magnetic field at all motor speeds and at all different loads.

Abstract: APPARATUS AND METHOD FOR DETERMINING THE POSITION OF A GAS-SATURATED POROUS ROCK IN THE VICINITY OF A DEEP BORE-HOLE IN THE EARTH             Abstract of the Disclosure Apparatus for determining the position of a gas-saturated porous rock in the vicinity of a deep borehole in the earth, drilled to a selected depth below the expected position of the porous rock.  The apparatus includes a source of seismic waves of selected characteristic, positioned at a selected point in the borehole, with an array of geophones positioned on the earth in known positions around the borehole.  These geophones are adapted to receive the seismic waves generated by the source in the borehole, after traveling upwardly through the earth, and to produce corresponding facsimile electrical signals.  If the seismic waves from the source, in their upward movement to the surface, pass through a gas-saturated porous rock they will be attenuated, and therefore the signals from the geophones which are in the shadow of this gas-saturated rock will show a change of character and/or an attenuation.  If the shadow is observed while drilling at two or more known depths, the depth, azimuth, and radial position, from the borehole, of the gas-saturated rock can be determined.  Using the principle of reciprocity, the same measurements can be made by inter-changing the positions of seismic source and receiving sensor.  A geophone lowered into an open borehole on a wire line will receive signals from a surface seismic source.  Attenuations along certain downward ray paths indicate the shadow zones from which the depth, size, and position of a gas-saturated reservoir can be deduced.
