Abstract: ABSTRACT   A structurally toughened heat resistant adhesive composition comprising a solution of polyisoprene elastomer in polymerizable  acrylate ester monomers.  The adhesive composition also contains an adhesion promoter, a cross-linking agent, a free-radical generator and a free-radical accelerator.  The adhesive compositions are generally used as two-part systems, and yield bonds with improved heat and solvent resistant properties. The polymerizable acrylate ester monomers may be monofunctional or a combination of mono- and polyfunctional monomers.  Among the useful classes of monomers are alkyl and cycloalkyl acrylates, alkyl and cycloalkyl methacrylates, alkoxy acrylates and methacrylates, alkylene diacrylates and dimethacrylates.  A few of the preferred monomers are methyl methacrylate, lauryl methacrylate, isobornyl methacrylate, and tetrahydrofurfuryl methacrylate.   The preferred polyisoprene rubbers are generally copolymers (or block copolymers) of (i) isoprene with styrene, acrylonitrile, or methacrylonitrile; (ii) homopolymers of polyisoprene; or (iii) copolymers of either (i) or (ii) with a functional monomer; or (iv) mixtures of the above.  Most preferred are the homopolymers of isoprene.

Abstract: A B S T R A C T            Counter circuit for counting high frequency pulses.           The counter circuit is adapted to counting high frequency pulses and to being read while counting said pulses.          It comprises a plurality of pulse counting stages of increasing numerical significance, and read means for reading the states of said stages.  Said plurality of pulse counting stages comprises lower significance stages (101 to 104) connected as a synchronous counter (10) and higher significance stages (121 to 12n) connected as a ripple counter (12).  The synchronous counter is so connected that it counts the high frequency pulses (H) directly, and that any change of state required in any of its stages on counting a pulse occurs substantially simultaneously with the arrival of said pulse.          The ripple counter is so connected that it counts count cycles of the synchronous counter, and that it takes a long time relative to the interval separating two successive high frequency pulses for a change of state to propagate, where necessary, from the least significant stage (121) of the ripple counter to its most significant stage (12n).  Early count signal means (244) are provided to apply a count signal to the ripple counter during each count cycle of the synchronous counter at an instant which is early relative to the synchronous counter cycling from its full count to its empty count.  Further, the  read means (49) are provided with read timing means (244 & 57) for causing the state of the ripple counter to be read regularly at a predetermined synchronous counter state.

Abstract: ABSTRACT OF THE DISCLOSURE   On a measuring table (1), a bridge (2) extends over a printed sheet (5) to be measured. A measuring carriage (3) carrying a three color-simultaneous measuring head is arranged on the bridge (2) for linear movement in a back and forth manner along a desired path on the printed sheet.  For control of the movement of the measuring head during measuring runs and for the evaluation of the measured data, a computer (7) with an integrated image display terminal and a processor system (6) controlled by the computer, is provided with the necessary interfaces.  The analysis of a color measuring strip (MS) located along the desired path on the printed sheet is effected in two phases.  In a first, so-called recognition run the measuring strip is scanned stepwise with high resolution in all three color channels, for the purpose of an analysis of its configuration.  By means of flat locations in the density variations, effective positions (e.g, the centers) in the measuring fields are determined as possible measuring positions for subsequent measuring runs.  During the measuring runs the measuring strip is measured only at the measuring positions determined during the recognition and the measured data obtained in this manner are transmitted for processing and/or display to the computer (7).  By the division of the measurements into a recognition and a measuring run, coupled with the determination of measuring positions by means of flat locations in the density variations, a practically completely automatic evaluation of the color measuring strips independently of their configuration and without the need of prior knowledge of the strips by the apparatus, is rendered possible.

Abstract: Abstract:    A jack pump of the type used to pump crude oil from oil wells.  The jack pump comprises a reciprocating hydraulic motor fox operating sucker rods extending down the well to a down hole pump.  The motor has a power stroke for lifting the sucker rods and a dissipating stroke allowing the sucker rods to fall again.  The jack pump includes a variable displacement hydraulic pump, a gas-charged accumulator, a reservoir for hydraulic fluid and a hydraulic flow control circuit connecting the motor, pump, accumulator and reservoir.  The flow control circuit allows the jack pump to operate as follows.  During the power stroke of the hydraulic motor, pressurized fluid flows from the accumulator to the motor to operate the latter.  During the dissipating stroke of the motor, fluid flows from the motor to the reservoir.  During both the power stroke and the dissipating stroke, the pump operates continuously and under balanced load to charge hydraulic fluid from the reservoir to the accumulator.

Abstract: ABSTRACT OF THE DISCLOSURE       A method of and apparatus for sorting pieces or particles of  radioactive  ore where  the particles are moved one after another substantially horizontally then discharged into a gravity-accelerated trajectory which is  substantially  free-fall  but  can  be  controlled  to follow a modified path by a low-friction slide plate. The  falling  particles  pass  a plurality  of  radiation detectors arranged in line along their path with in-creasing velocity due to gravity providing the required separation  of  the  pieces  so  that  each  detector  is subject to the radiations of essentially only one piece at a time.  The size and number of detectors and the path length covered by the detectors is determined by the size of the pieces and the cut-off grade and accur-acy required.  All counts corresponding to a particular piece and derived successively from the plurality of detectors are accumulated since accuracy increases and percentage of probable error decreases with increased total count.  The position and velocity of each piece are  determined  during  their  fall  to  provide  close tracking of the particle's path in space and time.  If the pieces are sufficiently closely sized the decision to accept or reject a particle may be made on the basis of total accumulated counts being greater or less than a preset figure.  If the pieces are not closely sized then the size of each particle is also determined and used in a counts/time/size computation which is compared with set cut-off grade data to provide a decision to accept or reject the particle.

Abstract: "COMBINATION SEEDER AND FERTILIZER SHOVELS FOR AIR SEED-ING DEVICES"          ABSTRACT OF THE DISCLOSURE         Conventionally, seeding takes place after broad-casting of fertilizer or after side banding of the fertil-izer takes place.  The former is inefficient and wasteful and the latter is of course inaccurate as it is difficult to locate the fertilizer in correct relationship to the seed.  The present device comprises a shovel which in-cludes a plurality of seed outlets at the rear thereof and a plurality of fertilizer shanks depending from the underside of the shovel and having fertilizer outlets at the rear thereof and being situated longitudinally between the seeding outlets.  The seed and fertilizer outlets are connected via manifolds to an air fertilizer and seeding device.

Data representing individual pixels is quantized into white, gray and black levels. During enhancement, gray pixel data is selectively changed to black or white while some black is changed to white, both operations depending on the white, gray or black levels in adjacent pixels.  The enhanced data is scanned for a multiplicity of simul-taneous conditions which define when a matrix of the data includes a character pattern which is optimally positioned within the matrix.
