Abstract: ABSTRACT OF THE DISCLOSURE         An image size control system for controlling the size of the image produced by pixels generated by a raster scanner.   A binary rate multiplier is used for image size control along the X-axis, the multiplier being programmed to the size image desired to vary the fre-quency  of  the  pixel  clock  signals  output  by  the multiplier.  A control flip-flop astride the image pixel stream is driven by the multiplier clock signals to speed up or reduce the rate at which image pixels are output with consequent change in image size along the X-axis.    For  image  size control  along  the Y-axis,  a phase lock loop speed controller  is provided for  the scanning carriage drive motor with programmable frequency generator.   The frequency output of  the generator  is settable to the image size desired, changes in image size being achieved either by increasing or decreasing the rate at which the scanning carriage is moved.

Abstract: ABSTRACT OF THE DISCLOSURE         A well completion and workover method wherein a sub-terranean formation is contacted with a high density, nondamaging treating fluid which comprises a saturated, aqueous saline sol-ution with at least one water soluble salt that is substantially insoluble in the saturated saline solution.  The water soluble salt has a particle size range of about 5 microns to about 800 microns, and greater than about 5 percent of the particles are coarser than 44 microns to control the pressure in the formation; to bridge and seal off the formation; to avoid particle invasion; and also to minimize fluid loss to the formation.  A minor amount of a fluid loss additive is included in the treating fluid to in-hibit loss of fluid into the formation and a minor amount of a suspension additive is included in the treating fluid to prevent settling of the water soluble salt particles in the aqueous saline solution.  The aqueous saline solution should have a den-sity of at least about 10 pounds per gallon,

Abstract: ABSTRACT OF THE DISCLOSURE:           Heat gellable droplets of a suitable liquid feed material are dielectrically heated to the gelling temperature by exposure to microwave radiation during free fall through a heating zone.  The gelled microspheres thus produced are caught and collected in a washing liquid.  The microwave radiation is provided through the use of a hollow cavity resonator.  And a vertical for microwave transparent tube extends through the resonator to delimit the processing zone for the free falling droplets.  Frequency control means and a reflected radiation measuring device are associated with the resonator and radiation generation means so that the opera-tion of the system may be closely controlled.

Abstract: ABSTRACT A transducer housing assembly for an ultrasonic flowmeter is disclosed. The housing may be made by an injection molding and preferably has a pair of pedestals for supporting the transducers at a specific angle while acoustically isolating the transducers from each other and providing an air backing for the transducers to improve the sensitivity of the transducer assembly.  The pedestals are integral with a base of the housing and the base has a partially-cylindrical concave external surface which has a radius of curvature less than that of the pipe to which it is to be clamped.  An acoustic coupling material is received in the space defined between the concave surface of the base and the convex surface of the pipe.  This material cannot easily escape from the space because of the firm connection of the base to the pipe along two parallel lines at the outer edges of the base.  This spaced parallel line connection also prevents rocking of the assembly on the pipe, a problem with prior systems.

Abstract: ABSTRACT An internal combustion engine analyzer provides both data acquisition and data processing and includes an analog waveform analysis subsystem together with a general purpose background system wherein appropriate power distribution is provided for the system as a whole and peripheral equipment such as a printer, keyboard and an analog/digital CRT is also provided.  The input signals to be analyzed are waveforms generally associated with internal combustion engines and peripheral equipment.  Exemplary waveforms are the primary and secondary ignition waveforms.  The waveforms are attenu-ated to reasonable levels and multiplexed to analog circuitry which serves to measure waveform magnitude at one or more sampling points along the length of the wave and to also measure the manner in which the characteristics of the waveform change.  The analog measurements are digitized and coupled to a processor which in turn controls the operation of the analog circuitry.  The digitized measurements together with previously entered engine identification data are analyzed by the processor to thereby control subsequent data taking and to generate appropriate maintenance and repair instructions which are communicated visually to an operator in the disclosed embodiment.

Abstract: IMPROVEMENTS IN DIELECTRIC CONDITIONING                  ABSTRACT OF THE DISCLOSURE     There is disclosed in the present application a method and apparatus for treating variable batches of moist dielectric materials by the application of radio frequency energy which reduces the moisture content.  According to the present method and by the use of the present apparatus, full power or another pre-determined power level from a radio frequency power source is maintained on the load by an electro-mechanical adjusting device which incrementally reduces the coupling between the source and the load until the boiling point of water is reached.  After the boiling point is reached, the coupling is incrementally increased to reach a pre-determined moisture content in the material being treated.  There is included in the present apparatus, means for counting the number of discrete coupling adjustments in both directions.  The difference between these two counts is utilized to select the final average moisture content of the batch and for terminating the treatment cycle when the load has reached the selected average moisture content.
