Abstract: ABSTRACT OF THE DISCLOSURE            Novel aqueous crosslinked gels are described herein which are useful for fracturing subterranean formations.  The novel gels are com-prised of a solvatable polysaccharide and a soluble zirconium crosslinking agent.  The zirconium cross linking agents are novel and are prepared by reacting a zirconium alkoxide with certain alkanolamines under anhydrous conditions.  The zirconium compounds are activated by contact with water.  As an example, a zirconium crosslinker was prepared by reacting zir-conium tetra(n-propoxide) with triethanolamine in an n-propanol solvent under anhydrous conditions.  The zirconium compound thus prepared was activated with water and used to form a stable aqueous crosslinked gel by blending the aqueous crosslinker into an aqueous hydroxypropylguar solution.

Abstract: Abstract:       This invention relates to a method and apparatus for judging the calibration of a voltage attenuation probe.  A square-wave signal is applied to the probe to be judged.          A reference level is adjusted to be within a selected range of a peak level of the output signal of the probe.          The reference level is compared with the output signal from the probe at a plurality of points along a portion of the output signal to provide a comparison result.  A juding takes place as to whether or not a duty factor of the comparison result is equal to a known duty factor of the square-wave signal.  The duty factor of the comparison result is computed according to the number of points at which the probe output signal is greater in magnitude than the reference level.  The probe is judged to be calibrated when the duty factors of the comparison result and the square-wave signal are equal to one another.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved process for drying water-wet, cellulose ester membranes is described.  It has been found that by contacting one side of the membrane with a liquid mixture of a water-miscible, volatile C1 to C6 hydro-carbon and a water-immiscible organic compound, while an inert gas stream or vacuum is maintained on the other surface of the membrane, water can be displaced from the membrane economically, rapidly and without adversely affecting the structure of the membrane.  A 1 to 1 volume mixture of isopropanol and isooctane is particularly preferred in this step.  The essentially water-free membrane is then dried by applying reduced pressure or an inert gas stream to produce a membrane having exceptional separation characteristics.   30,333-F

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus in which contaminants transferred from a copy sheet to a photoconductive member are attracted back to the copy sheet. During the transfer of the toner powder image from the photoconductive member to the copy sheet, the copy sheet contaminants are attracted to the photocon-ductive member. Simultaneously with this transfer process, the copy sheet contaminants have their polarity charged to the same polarity as the polarity of the charge on the toner powder image. In this way, the contaminants are attracted back to the copy sheet from the photoconductive member preventing contamination thereof.

Abstract: Abstract Regenerating Catalytic Particulate Filters and Apparatus Therefor A method and apparatus for regenerating a catalyzed particulate filter in the exhaust stream of a combustion source (particularly a diesel engine) are provided that do not necessitate excessive heating of the exhaust stream flowing from the combustion source.  During regeneration the intake air is supplied in a pulsed manner, preferably but not necessarily, to less than all of the cylinders of the engine so that the combined engine exhaust carries sufficient "fuel", primarily in the form of a carbon monoxide and a hydrocarbon fraction, that will be catalytically oxidized thereby generating an exotherm. Due to the liberation of heat during that carbon monoxide and hydrocarbon oxidation above the light-off temperature of the filter, the particulates stored by the filter will be ignited and burned, cleaning and regenerating the filter.

Abstract: ABSTRACT            An optical disk servo system includes a coarse access and tracking system for optical head control and a fine access and tracking  system  for  read/write  beam  control.   Enlarged servo tracks  are pre-recorded  on  the  optical  disk  between bands of data track locations.  The coarse system illuminates a relatively large  area  of the disk  surface  encompassing at least one  of  the  servo  tracks  and  detects  light  from  the enlarged illuminated area.  Suitable means including a photo-detector array  identifies  and  controls  the  optical  head position by means of the light returned from the  illuminated servo track.  Such photo-detection means are insensitive to light reflected from the data tracks.  The fine access and tracking system uses a conventional, three spot tracking and read system,two spots for data track following and one spot for data track reading.          The fine access and tracking system controls a galvanometer mirror or other suitable means steering the read spot beams.  Data writing is accomplished by fine tracking a previously recorded data track and maintaining the write beam a constant distance therefrom.

Abstract: ABSTRACT     The invention relates to a new method of assembly of pneumatic counterbalance units and to apparatus for carrying out that method.  Components of the unit are positioned within crimping die tools in a crimping press with a small quantity of lubricating oil pre-introduced into the cylinder component.  The die parts holding the components are moved in a direction towards assembly.  The die tool parts engage and provide a sealed compartment surrounding all components of the unit.  At this stage the compartment is pressurized by gas at several atmospheres and, while pressurized, press movement continues.  As the crimping die parts move together the piston assembly parts including the rod seal and the end bushing move into the cylinder and entrap a quantity of pressurized gas within the cylinder.  As press action continues, the open end wall portion of the cylinder is crimped inwardly by the crimping die tool, thereby retaining the bushing, seal, rod and piston in the cylinder and completing the assembly.  The sealed die compartment is vented, pressurization is released, the press is reversed and the tools move apart to permit removal of the assembled counterbalance unit.  The crimping die tools are structured so as to maintain the counterbalance components in their pre-assembly positions and to provide a closed sealed cavity around the components while that compartment is being pressurized and depressurized.
