Abstract: ABSTRACT OF THE INVENTION    Rotary processors and methods for mixing a low viscosity liquid with a viscous material while controlling plugging of the means for introducing low viscosity liquid to the processor.  Viscous material is introduced to a mixing rotary processor comprising at least one annular channel carried by a rotor and enclosed by a housing to form a mixing passage.  The material is dragged forward by the rotating channel walls from the passage inlet past a spreader as films on the channel walls, forming a void downstream of the spreader between the films.  Low viscosity liquid is sprayed from a point within the void to be deposited on and carried downstream with the films of material and to be mixed with material collected at a passage end wall. In one embodiment, pressure sealing means permits spraying into a saturated vapor zone in the void so that liquid vaporizes and is condensed onto the films as well distributed fine droplets.  An especially preferred embodiment provides devolatilizing apparatus in which a low viscosity, low boiling devolatilizing aid is deposited onto and mixed with a viscous material to aid in the removal of one or more difficultly devolatilizable impurities.

Abstract: SCANNING CONTROL SYSTEMS            Abstract A checkout system for processing purchased merchandise items includes a checkout counter in which is located a scanning assembly for scanning a coded label on the purchased item to produce data signals identifying the item purchased, a display member on the counter for displaying the price of the merchandise item purchased, an indicator light and a tone generator located in the display member, a back office processor for obtaining the price of the merchandise item scanned from a price look-up table using the data signals as an address and a data terminal device for printing the price of the items scanned on a record member.  Processing means located in the scanning assembly and the display member cycles the operation of the tone gnerates when the price of the item scanned is not found in the table and cycles the operation of the indicator light whenever a malfunction occurs in the operation of the terminal. In both cases, the operation of the scanning means is disabled.

Abstract: PHD 85 328                  14             21.4.1986 ABSTRACT: Circuit arrangement for sampling a ternary signal.     In a circuit arrangement for sampling a ternary signal, this ternary signal is divided by amplitude decision circuits into two binary signals and the binary sub-signals are sampled at m-times the rate of the symbol clock. The binary samples of each sub-signal are shifted through a shift register having at least m stages and intermediately stored in a buffer store  for one period of the symbol clock. With the aid of a logic circuit it is then determined in which regions of the buffer store accumulations of identical binary values occur.          Regions in which the accumulations always re-occur - the number of occurrences is checked by means of counters -are considered to be eyes of the ternary signal. In each clock period of the symbol clock, a sample falling within the eye of the ternary signal is transferred from each buffer store at an output of the circuit with the aid of a gate circuit.

Abstract: ABSTRACT         A conveyer-belt reeling device comprises an open box frame structure having an axle extending traversely the width of the frame.  One extension of the axle protrudes through an upper horizontal frame member for connection to a drive unit mounted externally of the frame. The opposite extension of the axle is located within an opposite frame member which is pivotally attached at each end and is therefore capable of pivotal movement in either direction to allow the lateral transference of the axle with its associated roll of belting.  A cradle is located in the bottom of the frame and extends traversely the width of the frame, being capable of vertical movement by means of an integrated lifting apparatus.

A  projection  extends outwardly  from  the  tip  portion.   A  piercable barrier    is   provided   for   preventing   fluid communication   between   the   chamber   and  the passageway.  A hub having a forward end, a rearward end   and   a   conduit   therethrough   is   movably positioned within the passageway.  A first cannula extends outwardly from the forward end of the hub and  a  second  cannula  extends  outwardly  form  the rearward end of the hub.  A needle shield movably engaging  the tip,  covers the first cannula.   This needle  shield  has  an  outer  extension  portion extending  over  a  portion  of  the  tip  which  is capable of contacting the projection for  limiting the motion of the needle shield toward the proximal end  of  the  barrel.   The  outer  extension portion also includes a longitudinal groove which is wider than the projection and  capable of  receiving  the projection   The  needle  shield  also  includes  an inner extension portion projecting proximally into the passageway and capable of contacting the hub. The     inner    extension    portion   is long  enough  so  than  when  the  needle  shield  is rotated to align the groove and the projection, and moved in a proximal direction with respect to the tip so that the projection enters the groove,  the inner  extension  pushes  against  the  hub  and moves the hub in a proximal direction causing the second cannula to pierce the piercable barrier.

Abstract: NO-TURN TOOL            ABSTRACT OF THE DISCLOSURE     Designed primarily for use in the production of heavy and medium oil in conjunction with a screw-type pump in rela-tively shallow or medium wells, the device comprises an inner mandrel within an outer casing situated below the pump and connected to the pump casing and prevents right-hand rotation in the event that the torque reaction of the pump increases due to sand, for example, and attempts to rotate the pump stator together with the production string  tubing,  but  at  the  same  time  allows  vertical movement  of  the  string  to  take  place  for withdrawal purposes.   Once the production string together with the pump and the no-turn tool  is  lowered to the  desired position,  drag blocks engage the well bore casing thus holding or steadying the outer casing while the inner mandrel is rotated slightly so that cams thereon force slips into contact with the well casing thus preventing right-hand rotation of the outer casing which, because it is connected to the stator casing of the pump and to the production tubing,  also prevents right-hand rotation of these parts thereby preventing separation at the loosest joint.   Shear pins are provided in the event that the slips catch in a casing joint, casing perforations or the like when withdrawing the tool and a shear ring on the mandrel shears these pins when vertical movement of the assembly is initiated thus clearing the cams from the slip blocks so that slip springs retract the slips and allow withdrawal to continue.

Abstract: An apparatus and method to determine with a high degree of precision the position of the inside wall of a translucent or transparent tube (10) comprises a laser beam at a wavelength for which the material being measured is transparent or translucent and a directing means (12) for aiming the laser beam toward the tube and normal to the axis of the tube while moving the aimed beam to traversely scan the tube. A light detection means (16), positioned to receive light polarized normal to the axis of the tube which light, having been reflected by the inside wall (14) and refracted by the tube, causes the detection means to generate signals. The signals are processed (23) to analyze when the light beam is reflected by and when the light is refracted at the inside wall (14) of the tube. The apparatus is also useful in connection with finding the position of the inside wall (14) of curved material of generally uniform thickness. The method includes the steps of aiming a beam of laser light polarized normal to the axis of the tube and intercepting the outside wall of the tube at a height substantially equal to the inside wall and normal to the axis of the tube (10) so that the laser light reflected by or refracted through the inside wall (14) can be detected and related to the transition point between reflection and refraction as a measure of the radius of curvature of the inside wall.
