Abstract: ROTARY DRILLING DRILL STRING STABILIZER-CUTTINGS GRINDER                               ABSTRACT          An arrangement for alleviating the problem of differential sticking of a drill string in rotary drilling of a highly deviated borehole by grinding and reducing the size of the cuttings generated by the drilling operation to enable the mud-return flow to better remove the cuttings from the wellbore.  At least one full gage, rotating stabilizer-grinder is placed along the drill string at a selected point in the high angle section of the hole.  In one embodiment, this stabilizer-grinder is constructed with an inner mandrel which is part of and rotates with the drill string and powers the first part of the grinder, and an outer mandrel which is free to rotate separately from the inner mandrel.  The outer mandrel is full gage and fits against the borehole wall such that it remains stationary with respect thereto.  The outer mandrel thus forms the second part of the grinder on which cuttings are broken and reduced in size.  In another embodiment, a downhole turbine mud motor powers a grinder positioned just above the downhole drilling collars.

Abstract: ABSTRACT OF THE DISCLOSURE         A chair of the tilting type which includes a base, a seat and back, with the base pivotally supporting the seat with two opposite non-parallel links of the four bar non-parallel linkage, with one of the opposite links ex-tending to support the back and also being formed to provide an arm rest.  The four bar linkage is duplicated on each side of the chair by forming the two opposite non-parallel links or cranks from the upturned ends of the tubes which pass through the base in parallel but vertically offset fashion, the base thus forming the fixed bar of the linkage with its opposite bar or coupler being formed by the seat. A spring within the base is operative on one of the tubes to urge the chair to an upright position.  The tubes are pivotally connected to the seat and one of the tubes extends and is fixedly connected to the back in a manner to emphasize the isolated and separate appearance of the seat and back. With the above construction the seat and back both tilt in their proper natural body support positions but in a respective ratio of about 1 to 3.  The chair thus obviates some of the problems of prior chairs where only the back tilts or both the seat and back tilt as a unit.

Abstract: MEDICAL FLUID MEASURING SYSTEM            ABSTRACT OF THE DISCLOSURE    A urine discharge measuring system for medical use which includes a gimbal mounted frame supporting a urine container of fixed dimensions to collect urine from a urinary catheter attached to a patient.  An ultrasonic transceiver mounted above the container and operated in conjunction with a microprocessor based control unit, positioned adjacent to the transceiver, periodically and automatically measures the height of the urine collected within the container.  The measured fluid height is converted to fluid volume by the control unit.  To maintain the  sterility   of  the  container,  the  transceiver transducer(s)  is mechanically isolated from the urine container by elements which allow the ultrasonic energy to be transmitted to and received from the interior of the container. In one described embodiment, desired measured volume accuracy is achieved by employing  a reflective target within the urine container at a known fixed distance from the transceiver transducer.  Comparison by the control unit of the measured distance with the actual distance to the target allows generation of corrections for variations of the speed of sound in air due to temperature and humidity to be applied when obtaining the urine height within the container.  Digital displays in the control unit provide indication of past and present accumulation of the urinary output of the patient.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the recovery of zinc from zinc-containing sulphidic material which also contains iron and from zinc oxide containing material, at least one of the materials containing lead and/or silver values. The process includes leaching zinc-containing sulphidic material and zinc oxide containing material under pressurized oxidizing conditions at a temperature in the range of from about 130 to about 170°C in aqueous sulphuric acid solution with a stoichiometric excess of sulphuric acid relative to the zinc content of the materials of from about 40 to about 100% to produce a residue containing a major proportion of lead and/or silver values and a leach solution containing a major proportion of the zinc and iron.  The residue is separated from the leach solution and treated to recover lead and/or silver values.  The pH of the solution is then raised to neutralize the acid in an iron removal step to cause precipitation of at least some of the dissolved iron from the leach solution as an iron com-pound.  The precipitated iron compound is separated from the remaining leach solution, and the remaining leach solution is treated to recover zinc.

Abstract: High Density Dot Matrix Printer ABSTRACT      A high density dot matrix printer is disclosed which can print characters with variable font and having print resolution close to that of a typewriter. Printing on both a forward and reverse pass of a line of characters with the dot print head coupled with offsetting the dot matrix print head for the reverse pass printing doubles the line density in printing characters to increase resolution. In addition, a compacted character code arrangement is utilized having a different printing code for the reverse pass printing than for the forward pass printing, and uses single binary words to represent many dot printing positions dependent on the location of the single binary word in the character code coupled with using single binary words to represent many possible dot positions in which no dots are to be printed. This compacted character code arrangement permits the use of a relatively small amount of memory and results in operating a larger number of print head pins in printing each character than heretofore practiced in the art to greatly increase print resolution. A lower level of increased resolution printing is obtained by utilizing the compacted character code technique for the forward pass printing but deleting reverse pass printing to increase printing speed when required.
