Abstract: 20.2149 METHODS AND APPARATUS FOR DETERMINING    DYNAMIC FLOW CHARACTERISTICS OF PRODUCTION FLUIDS IN A WELL BORE                    ABSTRACT OF THE DISCLOSURE        In the representative embodiments of the new methods and apparatus disclosed herein, a well tool incorporating the principles of the present invention is arranged for selectively discharging discrete minor quantities of a first radioactive tracer and of a second radioactive tracer.  When the tool is stationed in a production well, upon discharge of whichever one of the two tracers that is believed to be miscible in the continuous-phase fluid at that depth location, radiation detectors arranged at spaced locations on the tool respond to provide one or more measurements of the level of radioactivity in the well bore fluids from which one or more dynamic flow characteristics of the continuous-phase fluid at that depth location may be determined.

Abstract: ABSTRACT OF THE DISCLOSURE    The transmission means for transmitting a traction force to the middle truck defines a theoretical point of attack at a height (h) above the rails so as to have a moment exerted on the middle truck during traction which relieves the load on the leading axle of the middle truck by an amount equal to the relief force on each axle of the leading truck,  Likewise, a load is added to the trailing axle of the middle truck equal to the force added to each axle of the trailing truck.  This height is defined as h =    where a and b are the spacings between the axles and H is the height of the draw hook above the rails.

Abstract: ABSTRACT:               For recording and/or reproducing colour television signals steps are proposed which enable the crosstalk signal from an adjacent track to be suppressed during reproduction.  This is possible both for the chrominance signal and for the luminance signal.         For this purpose the polarity of the signals in the line periods in all tracks is switched during recording in periodically recurrent groups with the same pattern of consecutive polarities, the groups comprising at least four line periods and being offset relative to each other in adjacent tracks by at least one line period.         During reproduction the signals secured from the relevant track whose polarities have been switched, at least in respect of the chrominance signal, are restored to signals with the original polarities.         The frequency specific of the useful signal relative to the crosstalk signal from an adjacent track are then interlaced, which is utilized for suppressing the crosstalk signal.

By the use of such a specific catalyst, the selectivity for the desired acrylonitrile is remarkably improved, and there can be attained high yield of the product.   In the process of the present invention, the catalyst can maintain a high activity and a high selectivity for a long time, without undergoing attrition.  The catalyst is well prevented from sublimation-escaping of the ingredient molybdenum therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE A thermoplastic container having multilayered side-walls is compression molded from a multilayer billet having a first and a second thermoplastic layer, the layers being so adapted that when the thermoplastic material of the layers is heated to the heat softened state and a compressive force is imposed thereon, the layers are extruded at differential flow rates into a molding cavity whereby the fastest moving layer forms the flange and exterior surface portions of the container and the slower of the layers forms the interior surface of the multilayer container.  A multilayer container, having improved gas barrier properties, which can be sealed by double seaming to metal end closures without fracture, is obtained when the faster moving of the billet layers is comprised of a relatively flexible thermoplastic resin material and the slower moving of the layers is formed from a thermo-plastic resin having incorporated therein materials which improve the gas barrier properties of the resin.

Abstract: WIRELESS REMOTE CONTROL FOR ELECTRIC WELDER                 ABSTRACT OF THE DISCLOSURE      The position of the main rheostat on an arc welding  machine  determines  the  pre-set  welding current.  An operator, working at a location remote from  the  welding  machine,   carries  a  pen-type adjustable   rheostat   which  carries   calibrations indicative  of various  percentages  of the  pre-set welding  current.   There  are  no  extra  electrical connections,  such  as  wires,  between  the  remote rheostat and the welding machine.   If the operator wishes  to  change  the  magnitude  of  the  welding current, he need not return to the main rheostat at the  welding machine,  but instead merely sets the remote rheostat for the percentage of pre-set current desired, and inserts the remote rheostat between the electrode  holder  and  the  workpiece.   The minimum resistance of the remote rheostat is  sufficiently high to present an arc from being struck.  A current transformer in the welding machine senses the output (calibrating)  current  flowing  through  the welding cable.  A signal proportional to the desired welding current reference is compared with a stored value of the present welding current reference to produce a control signal which is fed to an up/down counter whose output is the stored welding current reference. The  welding  current  reference  is  thus  either increased or decreased until it reaches the value called for by the adjustable remote rheostat.  After a  few  seconds,  the  operator  removes  the  remote rheostat from the electrode holder, and the welding current reference will now be at the precise desired value to produce the desired welding current.

Abstract: ABSTRACT             Labels for use as markings that can be judged by later observers as to the validity of the marking.  The labels comprise a handleable support sheet and a fragile easily tearable heat-softenable film adhered to the support sheet.  A visible or machine-sensible component, such as a printed image, extends over the area of the film.  The film extends beyond at least one edge of the support sheet and carries a layer of adhesive so that it can be adhered to an article that is to be marked.  Upon removal of the label from the marked article, the extending portion of the film will tear and remain adhered to the article.  The removed label will not be useful if applied to another article with a portion missing.  Also, if an  attempt is made to superpose a label removed from one article with a torn portion of film remaining on a different article, the statistically likely mismatching of the label and torn portion, e.g., through mismatching of the visible or machine-sensible component, will reveal the transfer.

Abstract: ABSTRACT OF THE DISCLOSURE                An adapter for connecting in fluid communication a liquid dispensing syringe with the interior of a bottle containing a liquid, such as a liquid medication, includes a tubular body member composed of resilient material and being  generally cylindrical in shape to fit snugly within the mouth of the bottle.  Projections or beads are provided on the body member for engaging the inside surface of the bottle thereof in a continuous line of engagement therewith with a high pressure per unit area of engagement.  An opening extends axially through the body member for receiving the nozzle of the syringe, and the opening includes a forward nozzle receiving portion and a rear portion.  The axial length of the forward portion is substantially the same as the axial length of the nozzle so that the exit end of the nozzle terminates at the rear enlarged portion when the nozzle is inserted fully within the opening.  A fluid pathway disposed at the rear portion of the opening for the adapter guides liquid to the forward nozzle receiving portion and prevents or minimizes the introduction of air into the attachment opening.  In one form of the invention, the fluid pathway is in the form of an enlarged portion of the opening to prevent air from entering the syringe when the bottle is inverted to fill the syringe.
