Abstract: METHOD TO DIVERT STEAM FOR THERMAL RECOVERY PROCESS               ABSTRACT          The sweep efficiency of a steam flooding process is significantly improved if steam is injected into the lower portion of the formation via an injection well and fluid including oil is produced from the formation via a production well until steam channeling or steam overriding has occurred, after which steam injection is terminated and a predetermined amount of an oxygen-containing gas such as air, oxygen-enriched air, or oxygen is injected into the formation which oxidizes the residual oil in the portion of the formation where steam override or channeling has occurred forming an asphaltic material in that zone that increases the permeability of that zone.  Thereafter, steam injection is resumed and as a consequence of the oxidized asphaltic material plug, the steam moves into portions of the formation to mobilize viscous oil not swept by the initial injection of steam.  During injection of the oxygen-containing gas production of oil may be terminated or continued, however if production is continued, the rate of gas injection is higher than if the production well is shut-in.  Multiple cycles of steam and oxygen-containing gas injection may be applied to a formation to better control sweep efficiency.  The process may be applied using an oxygen-containing gas or a mixture of steam and an oxygen-containing gas.

Abstract: ABSTRACT OF THE DISCLOSURE           A surface acoustic wave (SAW) device con-figured to operate as a spectrum analyzer, and having an array of input transducers disposed on a substrate in such positions as to produce a focused beam of acoustic energy at a focal arc, each position on the arc being representative of an input signal frequency.          Output transducers produce electrical signals corres-ponding to the energy received at successive segments of the focal  arc.   The disclosed device includes various combinations of input transducer array improve-ments, some of which are to provide amplitude weighting of the input array, including aperture width weighting, capacitive weighting, resistive weighting, series-parallel weighting,  and  source withdrawal weighting.          Another  improvement  in  input  array  configuration eliminates close or overlapping electrodes of opposite polarities and thereby reduces parasitic capacitance and acoustic radiation between electrode elements.  The use of curved input transducer fingers improves opera-tion of the tranducers as point sources.   Other im-portant  improvements  include the  use of  acoustic transducers before to transmit the focused output energy from the focal line to conventional output transducers,  thereby  improving  frequency resolution, and the use of electromagnetic waveguides to transmit energy from output transducers located on the focal line.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method and equipment for the detection of mechanical injuries in the lumbar spine of a patient and the identification of these injuries, using a mathematical model applicable to the five lumbar vertebrae of a human being, and to their disks.  According to this method, the electro-myographis (EMG) activities of the erectores and abdominals of the patient are measured in the bilateral and symmetrical manner with respect to the spine of the patient while the same is flexing forward in the mediane plane and pulling up a small load.  The angle of flexion   of the patient is measured during this flexion and is supplied as variable input to the mathe-matical model.  A computer is used to run the model with its variable input in order to calculate the EMG activities of the erectores and abdominals that would normally be used by a healthy person to produce the same task.  The so calculated EMG activities are then compared to the EMG activities actually measured on the patient and the parameters of the models are tuned to fit the calculated EMG activities for those measured on the patient.  The amount and type of tuning that are necessary to complete the last step, are sufficient in practice to detect and identify the mechanical injuries that may be present in the lumbar spine of the patient.

Abstract: ABSTRACT A timing recovery circuit includes a detector for detecting the varying points of a split-phase signal having a repeating logical "1" and "0" pattern at its beginning.  A voltage-controlled oscillator (VCO) generates a signal whose frequency is twice as high as that of the timing signal of the split-phase signal and controls the frequency of the generated signal in res-ponse to a control signal.  A frequency divider divides by two the output frequency of the VCO.  A selector selectively supplies the output of the VCO and that of the frequency divider.  A phase detector phase-compares the output of the varying point detector and that of the selector, and supplies the VCO with a signal indicating the relative delay or advance between the two outputs as the control signal.  A control circuit controls the selector so that it selects the output of the frequency divider during the repetitive pattern of logical "1" and "0" and that of the VCO elsewhere.  The invention permits large scale integration and permits the frame length of data to be large without requiring a highly stable oscillator.

Abstract: ABSTRACT OF THE DISCLOSURE           A time independent data transmission system which allows a computer to access a remote data set at any time via non-dedicated telephone line is disclosed.  The system is coupled to a telephone instrument, a data set and the telephone transmission line and normally connects the data set to the telephone transmission line.  The telephone instrument is normally disconnected. In a preferred embodiment, a counting circuit senses the number of ring bursts in a ringing signal from a caller and a central computer is programmed to transmit a ringing signal having only one ring burst.  When only one ring burst is sensed, the data set remains connected to the telephone transmission line and the data set begins to communicate with the central computer when the ringing signal terminates.  If more than one ring burst occurs, a non-computer call is being sensed and the data set is disconnected and the telephone connected to the telephone transmission line so that normal telephone usage is allowed.  Communication between the computer and the data set via the telephone line occurs without ringing the telephone instrument and without otherwise interfering with normal telephone usage.  In the event the user wishes to use the telephone instrument at any time, including the time when communication between the computer and data set is taking place, a subscriber priority circuit allows the user to recouple the instrument to the line by merely lifting the telephone handset and to decouple the instrument by replacing the handset.

Abstract: Abstract of the Disclosure Apparatus for determining the depth of precipitation accumulating on the surface of a pathway, such as an airport runway or the like, includes a sensor having electrical trans-ducer means for emitting and sensing ultrasonic energy and having a body of material adapted to be embedded in the path-way with the top surface of the body being substantially flush therewith and exposed to the precipitation, the transducer means being physically coupled to the body.  A circuit causes the transducer means to emit pulses of ultrasonic energy, which are reflected as first and second reflections from the top surface of the body and from the upper surface of an accu-mulation of precipitation on the top surface of the body and are respectively returned to the transducer which, in response to the reflected pulses, produces corresponding first and sec-ond electrical signals.  An amplifier is connected to the transducer means for amplifying the first and second electri-cal signals corresponding to the first and second reflections, thereby to produce an amplifier output.  Another circuit is connected to the amplifier for initiating a first timing sig-nal upon the occurrence of the first electrical signal.  A further circuit compares the amplifier output with a threshold level which has a magnitude that decreases with time, the op-eration of the comparing circuit being started upon an occur-rence of the first timing signal, the comparing circuit initi-ating a second timing signal when the amplifier output reaches the threshold level.  Still another circuit in the apparatus generates a third electrical signal representing the depth of the precipitation as a function of the time interval between occurrences of the first and second timing signals.  Other circuits and methods for depth and related measurements are also described.

Abstract: ABSTRACT:          "Conductivity-enhanced combined lateral MOS/bipolar transistor"     A semiconductor device comprising a combined lateral MOS/bipolar transistor includes an intermediate semiconductor layer (16) of the same conductivity type as the channel region (20), which layer extends laterally from the channel region to beneath the drain contact region (24) of the device. Additionally, a floating semiconductor layer (14) of opposite conductivity type to that of the channel region (20) is provided between the inter-mediate layer (16) and the substrate (12) of the device. Both the intermediate layer (16) and the substrate (12) are relatively lightly doped, to effectively isolate the floating layer (14) from above and below. This structure substantially improves the oper-ating characteristics of the device, thus permitting operation in both the source-follower and common-source modes, while also pro-viding a compact structure which features a relatively low normal-ized "on" resistance.
