Abstract: ABSTRACT   In the manufacture of a packing container laminated packing material is used which with the help of a rotating cylindrical cutter is made thinner within a limited longitudinal region.  This reduction of thickness has been difficult to realize up to now with the desirable accuracy, since the specified depth of cut that has been set may readily be influenced by vibrations in the moving material or in the cutter.   These difficulties are overcome in accordance with the invention by means of a guiding device arranged in the immediate vicinity of the edge of the cutter which limits the thickness of the strip cut away. The guiding device is suspended in contact with the cutter in such a manner that not only are the vibrations reduced, but also the influence of the remaining vibrations on the depth of cut is minimized.

Abstract: METHOD FOR STIMULATING SILICEOUS SUBTERRANEAN FORMATIONS                   ABSTRACT     Wells of subterranean siliceous formations contain-ing hydrocarbons are stimulated by the injection of  cross-linked acid polymers wherein the polymer is a polysaccharide selected from the group consisting of carboxymethyl hydroxy-propyl guar and carboxymethyl hydroxyethyl cellulose. The crosslinked  acid polymer is a gel formed from a hydrated polysaccharide sol containing from about 1 to about 15 weight percent hydrochloric acid and from about 0.2 to about 6 weight percent hydrochloric acid to which a water hydro-lyzable polyvalent metal salt is added to cause the cross-linking.  The metal salt is zirconium, titanium or hafnium. Additionally an adjunct salt can be added in an amount of from about 5 to about 50 pounds per 1,000 gallons acid prior to the addition of the hydrolyzable polyvalent metal salt.     The crosslinked acid polymer retards the chemical re-activity of the acid mixture of hydrochloric and hydro-fluoric acid, thereby allowing the acid mixture to pene-trate deeper into the formation before the activity of the acids are spent.  After its injection, the crosslinked acid polymer breaks down as a result of time and temperature of the reservoir into a less viscous fluid allowing the acids to react with the formation.

Abstract: ABSTRACT OF THE DISCLOSURE           An  image  signal processing  architecture  for image  filtering  using  high  and  low  image  resolution scanning arrays to scan a document original.  The image pixels produced by the high resolution scanning array are analyzed to determine  the presence of high frequency halftone image pixels.   Where high frequency halftone image pixels are not found, the image pixels are filtered to enhance the signal content and thereafter thresholded adaptively.  Where high frequency halftone image pixels are determined to be present, the pixels produced by the low  resolution  array  are  descreened  and  thereafter rescreened at different  screen frequency.   A control switch permits the user to process continuous tone images directly.  In the principal embodiment, both high and low resolution  scanning  arrays  are  disposed  on  a common substrate to form a unitary structure.   In a  second embodiment, separate scanning arrays are spaced at preset distances from the object plane to provide the requisite high and low image reading resolutions.   To correlate image resolutions between the scanning arrays interpola-tion means are provided to interpolate additional image pixels in the output of the low resolution array.

Abstract: Abstract In screening apparatus for paper making stock incorporating a cylindrical screen member provided with screening perforations which are circular in section, the screen member is provided with multiple bars extending generally axially thereof in circumferentially spaced relation along the inlet side thereof to define with the adjacent surface of the screen member a series of pockets.  The radial dimension of these bars is such that the bars occupy a sufficient portion of the distance between the screen member and the rotating vanes in the supply chamber of the screen to interrupt the circulation of the stock adjacent the inlet side of the screen member and thereby to develop turbulence in the stock within each pocket.  Test results have established that this construction and mode of operation result in significant increase in the capacity of the screen in terms of the tonnage per day of accepted stock and also in the avoidance of fractionation of the stock on the basis of fiber length.

Abstract: NEH:em FLEXIBLE BAG WITH RECESSED SCRAPLESS HANGER          Abstract of the Disclosure A hanger construction for a collapsible contain-er for medical fluids which is fabricated in such a manner that it is scrapless and positioned within the confines of the container.  The hanger is formed with tear and hinge lines so that one or more tab portions are easily torn from and displaced from the bag surface to provide a hanger hole.  Hinge lines are positioned to afford a biasing of the displaced portions outwardly from the bag surface so that they will not "reclose" in the hanger hole.  A tear point is utilized for ease in initiating the tearing away of the tab portions.  The resulting hanger hole is of a geometric configuration in that it will accommodate most any support structure and the displaced portions are of a configuration in that they will not "hang up" or "dig" into the support structure.  These features permit ease of fabrication and placement of the bag over a support device.

Abstract: Abstract of the Disclosure An ocean mining system for mining manganese nodules comprises a sur-face subsystem and an ocean bottom subsystem.  The ocean bottom subsystem includes a mobile maneuverable, self-propelled, miner vehicle which picks up, handles, washes and crushes nodules while retaining nodule fines.  The under-water subsystem also includes a buffer which functions to provide temporary storage for nodule material picked up and crushed by the miner vehicle.  The buffer further serves to isolate the miner vehicle from the  dynamics of a pipe string extending down from a surface ship.  All equipment not needed for operation of the miner vehicle is located on the buffer to distribute the weight between the buffer and the miner vehicle in a way that provides maximum mobility of the miner vehicle.  The underwater subsystem also includes a flexible link-age, extending between the  miner vehicle and the buffer.  A flotation block holds the flexible linkage up and out of the way of the miner vehicle during operation of the vehicle.  This flexible linkage permits operation of the miner vehicle within a boundary envelope beneath the buffer as determined by the flexible linkage.  The surface subsystem includes a ship which provides all operational control and maintenance support for the bottom subsystem.  The ocean mining system includes sensors and controls.  The sensors sense the location of the miner vehicle within the permitted area of operation, display the topography of the ocean floor adjacent the miner vehicle and also display all aspects of the movement of the miner vehicle and pick-up and handling of the nodules.  The controls provide active control of every com-ponent of the  ocean bottom subsystem from the surface ship.

Abstract: ABSTRACT OF THE DISCLOSURE        A small, inexpensive apparatus for receiving and purifying the smoke generated at a welding station comprises four serially arranged chambers and a gas flow conduit, with a vacuum means for drawing the smoke through the conduit.  The conduit is equipped with fixed vanes to induce circulatory motion of the gas therein, and a circumferential aperture so that heavy particles forced to the outside of the conduit by the centrifugal force induced by the vanes exit through the circumferential aperture.  The gas and particles thus removed pass into a water bath, in which the particles are absorbed, the purified gas passing through the water and recombining with gas in the conduit, through an inlet aperture disposed in the second chamber.  The purified gas proceeds out of the conduit in a third chamber, where it impinges upon a surface bearing adhesive coating to remove the fine suspended particles from the gas, and leave substantially clean air to issue from the apparatus.

Abstract: CIRCUIT AND METHOD FOR MEASURING PSA OUTPUT                 AND ENERGY Thomas C. Barthel ABSTRACT OF THE DISCLOSURE Apparatus and method for accurately measuring the energy output of a pacing system analyzer or other pulse generator.  Voltage measurements are made across the output capacitor before and after the pulse is generated.          These voltages are measured by a microprocessor using an analog-to-digital converter and various gating and control circuitry.  By using a known value of capacitance for the output capacitor along with the voltages measured before and after the stimulation pulse is generated, the microprocessor can calculate the total amount of energy within the stimulation pulse.  This value is displayed on an integral display device.  Through the use of additional circuitry, measurements may be made for both atrial and ventricular stimulation pulses in a dual chamber stimulation device.  Provisions have also been made for measuring the output energy for constant voltage pulse generators.  This technique employs measurement of pulse width.
