Abstract: METHOD AND APPARATUS FOR CONTROLLING CHARGE ON A PHOTOCONDUCTOR       Abstract of the Disclosure In an electrophotographic reproduction apparatus and method a corona charger is used for depositing an electrostatic charge of one polarity upon a moving photoconductor prior to making an exposure.  In a calibration phase, an electrometer moves across the photoconductor and measures the level of charge at selected locations across the photoconductor to provide data regarding the distribution of charge in a direction transverse to the photoconductor's direction of movement.  This data is compared with a desired range of values.  Where the level of charge is measured at some locations to be outside of the desired range of values, then the level of charge at such locations is adjusted differentially.

Abstract: ABSTRACT In the process, two signals are created. The first signal allows the detection of a periodic signal for a short time preceding the theoretical timing position of the periodic signal. The second signal is transmitted a very short time after the theoretical timing position of the periodic signal and serves as substitute periodic signal when the periodic signal has not been detected prior to transmission of the second signal. The circuit, used to receive broadcasted digital data, is comprised of a counter (L), a D flip-flop (Bl) and a clock (CLX) whose frequency is equal to a multiple of the data bit rate to be received. The counter (L) has an initializing input connected to the Q output of the flip-flop (Bl). It has two outputs (X, Y) corresponding to the transmissions of the first and second signals. The first output (X) is connected to the 1 setting input while the second output is connected to the O resetting input of flip-flop (Bl) whose D input is connected to a O level voltage and clock input receives the periodic signal.

Abstract: MISCIBLE FLOODING AND WATER PRODUCTION OF PREVIOUSLY               WATER FLOODED RESERVOIRS     (D#77,400-TCRL-011) ABSTRACT     The invention is a tertiary hydrocarbon recovery method to be used with reservoirs which do not communicate with an aquifer and that have been previously waterflooded.  The method is performed by injecting a miscible solvent into the reservoir to form an oil bank from the hydrocarbons therein.  Water is con-currently produced from the waterflooded region of the reservoir.          The oil bank, followed by the miscible solvent, is driven through the waterflooded region of the reservoir to resaturate the water-flooded region with oil.  The following miscible solvent bank sweeps the oil from the region newly resaturated with oil.          Complete production of the oil is delayed until after the leading edge of the oil bank has passed through the previously water-flooded regions of the reservoir.

Abstract: I.       BOREHOLE COMPENSATED OXYGEN ACTIVATION       NUCLEAR WELL LOGGING      (D#76,104 -F) ABSTRACT OF THE DISCLOSURE      Formations adjacent a well borehole are activated with neutrons from a pulsed neutron source in a sonde at an energy level, such as 14 MeV, to energize oxygen present in the formation and borehole, giving rise to gamma radiation from 016(n,p)N16 reaction.  Gamma radiation in the energy windows 3.25 - 4.00 MeV and 4.75 - 7.20 MeV is detected in a time gated detector and counted.  Count rate contributions from the borehole and from the formation are differentiated on the basis of radial distance from the center of the sonde.  In this manner, compensation for adverse effects of borehole oxygen activation on formation oxygen activation measurements of interest is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE An anchoring system for semisubmersible drill rigs is described which includes a wire rope-chain cable anchor line and in which system components co-operate to convey the junction of the wire rope and chain cable smoothly over a fairlead sheave. The connector joining the anchor line has a narrow end in which the rope is rigidly retained, a large end at which a chain end link is pivotally retained, and a radially symmetric, generally concave surface extending between the two connector ends. The outer surface of the connector is shaped to seat in a sheave groove which otherwise serves to convey the chain cable, in a predetermined orientation in which a limited fixed bend angle is formed between the connector and the wire rope. The geometry of the connector naturally biases the connector to seat in the fairlead sheave in the predetermined orientation during hauling in of the anchor line. A collar fitted about the penultimate chain link displaces the large connector end from the sheave during paying out of the anchor line until the outer connector surface can be drawn by the wire rope into engagement with the sheave. Wire rope bending is accordingly minimized without significantly enlarging or altering the size of the fairlead sheave.

Abstract: ABSTRACT OF THE DISCLOSURE     An electronic stringed musical instrument having an electrically insulating fingerboard is disclosed.  The fingerboard is provided with a number of segmented frets attached across its upper surface at desired points along its length.          Each of the frets includes a number of electrically conducting fret segments each of which are electrically insulated from one another.  Any number of strings may be provided on the instrument each string is disposed adjacent to and associated with a single fret segment of each of the segmented frets.  A top-octave generator and octave dividers are utilized to selectively provide a fret segment of one of the frets with an electrical signal of at least one known referencing frequency.  The strings are attached to the instrument in a spaced relationship with respect to the fret segments.  Displacing a string to contact one of the fret segments completes an electrical circuit having at least one frequency equal to a frequency of the signal provided to that fret segment.  Displacing the same string to contact a different fret segment completes a different electrical circuit having at least one different frequency.  Simultaneously depressing a plurality of the strings simulataneously completes a number of electrical circuits each capable of producing a number of different frequencies.  The amplitude output of the instrument is dependant upon the voltage applied to each of the strings and is controlled by hand operated transducers.

Abstract: BRUSHLESS DC MOTOR            Abstract of the Disclosure A brushless DC motor having a number of armature poles which is neither a multiple for a submultiple of the number of field poles, thereby providing a relatively high cogging-ripple frequency.  The field pole facts, which are generally arcuate in cross-section, have centrally disposed depressions.  These depressions reduce the torque exerted by the armature when pole boundaries of the armature pass by the centers of the field poles. This reduces both torque ripple and cogging ripple and it doubles the frequency of torque ripple.

Abstract: In the case of a process for producing pourable spherical-segment-shaped packing material particles made of plastic which have an external convex and an internal concave surface, the plastic material is mixed with additives, such as bubble forming agents, coloring pigments and similar agents. The plastic material is fed, by means of a feeding funnel into an extruder through an opening in a bush surrounding the extrusion screw The plastic material plasticizes over the course of the extruder and, because of the difference in speed existing over the cross section of the mass, comes out of an opening in the die with a bent surface. The plastic material is cut off directly at the opening of the die and before any considerable expansion has taken place. Before the processing of the plastic granules in the extruder a bubble-forming agent is applied to their surface in a drum.

Abstract: Abstract of the Disclosure In a liquid crystal device one interior surface of the cell is coated with a polymer (e.g., a crystalline polymer such as PET) which, when rubbed, produces alignment of the liquid crystal molecules, and the opposite interior surface is coated with a material (e.g., an amorphous polymer, such as PMMA) which, even if rubbed, does not produce such alignment.  Also descried is a combination of an aligning polymer and a non-aligning, non-polymer (e.g., a silane surfactant or bare ITO).  This technique is particularly useful in producing alignment of relatively thick, ferroelectric smectic liquid crystal cells.
