Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure is directed to a process for producing a reverse osmosis module in which a tubular reverse osmosis membrane is wrapped about a coil form.  The tubular reverse osmosis membrane is manufactured of a desired length, after which a porous supporting member is applied to the exterior of the tubular membrane to enable it to withstand internal pressu-res.  Then couplings are applied to the opposite ends of the tubular membrane and the supported tubular membrane is heat treated under predetermined conditions of temperature and pressure which are selected as of 72° to 94°C, and 5.2 to 9.4 kg/cm2, respectively.  The process is also characterized by winding the supported tubular membrane on to a coil form to form a helical module under conditions substantially the same as those employed for the heat treatment, these conditions being continually maintained during both the heat treating and wind-ing steps.  A reverse osmosis module produced in this manner has average rejection characteristics above and beyond the rejection characteristics of modules formed in known manner.          The process is economical in that the heat treatment and coiling steps are carried out either sequentially or partly or completely simultaneously.  The processing is more economical because the module is manufactured employing fewer steps and less handling so that the possibility of operator error is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of producing a concentrated sodium carbonate solution low in calcium from calcined natural trona to minimize the deposition of pirssonite on the surfaces of processing equip-ment exposed to the solution from which the insoluble impurities, normally present in natural trona, have been separated.   The method comprises dissolving the calcined trona in a hot aqueous medium to form a concentrated solution containing insoluble impurities and soluble calcium salts and adding an amount of pirssonite effective to insolubilize the major portion of the soluble calcium in the sodium carbonate solution.  The pirssonite may be added to the calcined trona either before,during or after its dissolution.  The pirssonite may also be added by recycling excess muds back to the sodium carbonate solution from which the insoluble impurities have not been separated.  In addition, the sodium carbonate solution may be aged in the presence of the contained insoluble impurities prior to their separation from the sodium carbonate solution to reduce the amount of soluble calcium salts.

Abstract: ABSTRACT OF THE DISCLOSURE           In apparatus for deflashing thermoplastic articles which includes an edge member for slicing through the flash and guide means for the articles during slicing, there is provided temperature sensing control means upstream of the edge member, a rotating screw and adjacent support bar for delivering the articles to the guide means, a retractable support bar section and reciprocable plunger operable in response to a signal from the temperature sensing control means and individual deflashed article carrier assemblies linearly moving beneath the edge member.   The  process involves supplying untrimmed thermo-plastic blow molded articles, such as preforms, having in the region of the joint of a neck moil and the rest of each preform a cool outer skin at a temperature approaching the surface temperature of the blow mold cavity and an inner wall between the skin temperature and the extrusion temperature, sequentially advancing such untrimmed preforms toward a deflashing station while allowing the thermoplastic in such region to partially equilibrate in temperature through the full wall, sensing the surface temperature in such region upstream of the deflashing station and determining whether it is within a predetermined range with respect to the glass transision temperature of the thermoplastic material, ejecting untrimmed preforms whose surface temperature is outside this range, slicing through the thermo-plastic in said region of non-ejected preforms in the deflashing station to remove the moils and then catching them in holders as they fall by gravity after removal of the moils.

Abstract: ABSTRACT:              A television camera tube is provided with a discrete structure of photosensitive elements provided on an electrically conductive carrier. By applying to the conductive carrier a potential which is suitable for that purpose, which carrier is covered entirely with photo-conductive material or another resistance material, a potential distribution occurs having successive saddle points  for the scanning beam. Variation and exposure of the discrete photoconductive elements then results in a variation in beam splitting in the saddle points. As a result of this a greater or smaller extent of natural amplification can be given to the tube.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention disclosed sets forth a method and machine for forming a sleeve of a shrinkable, cellular polymeric material from a predecorated web.  The web is processed to provide (1) a partial-depth slit along the longitudinal dimension, and (2) cross-dimension pleats.  Predecorated shrunken neck labels are formed from the web for overlying the neck and closure of the bottle and including a pilfer-proof feature.  Such a label is formed from the processed web by cutting a blank having the cross pleats therein and winding the blank on a mandrel to overlap the ends and seam the overlap to make a sleeve.  The sleeve is stripped onto the top neck end and over the closure of a bottle of room temperature to a label position and shrunken to a snug fit, the pleats absorbing wrinkles that occur in shrinking the material onto a "cold" bottle.

Abstract: PROXIMITY SWITCH                 Abstract of the Disclosure A proximity switch is connected to close a circuit between a source and a load when a metal object is adjacent to a coil in the switch.  The coil is part of an oscillator circuit that is selected to have its output damped below a selected amplitude when the metal object is close enough to the coil.  The reduced amplitude of oscillation opens a capaci-tor shunting switch thereby permitting the capacitor to be charged.  The charging of the capacitor to a selected level turns on an SCR to connect the load to the source through the SCR.  A power storage circuit has a capacitor that is charged when the SCR is turned off to provide operating current for the circuits of the switch when it is not available because the SCR is turned on to shunt the current from the main power source.  A circuit for controlling the proximity switch upon initial energization prevents spurious operation with a switching circuit that does not turn on until after a selected period of time after energization of the proximity switch from the main power source.

In one aspect, the system includes an apparatus mounted at the stern of the vessel and coupled to the near end of the streamer.  This apparatus is adapted to provide measurements of the yaw and pitch of that por-tion of the streamer adjacent the vessel.  These measurements are employed in the generation of the position model.

Abstract: ABSTRACT OF THE DISCLOSURE         To place a driven shaft in accurate angular alignment with respect to a continuously rotating driving shaft or selective-ly, with respect to a fixed reference, the fixed reference is formed as a housing, the driving shaft has a disk with a cam track attached thereto, and the housing likewise has a disk with a cam track.  The driven shaft has an engagement pin connect-ed thereto, axially slidable and  engageable, respectively, with the cam tracks of the driving shaft, or of the housing.          The cam tracks are arranged to carry along and gradually accelerate the pin coupled to the driven shaft until the pin locks at a predetermined position in the cam track to define the relative angular position of driving shaft and driven shaft; upon different axial movement, the engagement pin is permitted to slide out of engagement with the cam track disk coupled to the driving shaft and engage a similar, and stationary cam track on the housing, again formed with a stop or rest position which again determines the angular relationship of the driven shaft with respect to the housing, and hence with respect to the reference.  Axial sliding movement of the engagement pin is controlled by pneumatic pressure acting on spring-loaded pistons.  The clutch is particularly useful in connection with printing machinery, especially rotary screen printing machinery, to provide for accurate alignment of intermittently operating printing stencil cylinders with respect to the instantaneous angular position of the machine drive shaft.
