Abstract: SYNTHETIC PLASTICS ARTICLE MANUFACTURING SYSTEM                 ABSTRACT OF THE DISCLOSURE     An extruder or the like, continuously issues a heated plastics material in the form of an elongated web, which is moved sequentially to molding and article severing sta-tions.  The products cut out are moved to lip rolling printing and drying stations.  Articles such as containers are formed by the mechanism which includes a turntable assembly for varying the length of the web travel path between an extruder and forming station to thereby control the residual heat in the web at the time of forming, and a molding drum with im-proved plug assist devices which are air powered and also in-clude air emitting ports to move the web into intimate engage-ment with the mold cavities as a final forming step under con-trolled conditions which assure that the pressure is applied at exactly the proper time.  The system includes a lip curling system which feeds containers severed from the web in step-wise fashion through forming roll sections and releases them in timed relation to indexible mandrels. The system further includes a Printing assembly which utilizes offset printing mechanism in combination with the mandrels, and associated ink drying mechanism, to print the containers prior to re-leasing or ejecting them.

Abstract: ABSTRACT     Solar distillation apparatus are disclosed in which a substantial part of the heat of condensation of the condensing liquid is recovered.  A conduit having an inclined smooth lower surface is disposed above the liquid to be dis-tilled and on which the evaporated liquid condenses and re-leases its heat of condensation.  A fluid is circulated through the conduit in a heat exchanging relationship with the lower surface thereof, the fluid absorbing a substantial part of the released heat of condensation. The condensed liquid flows along the bottom of the inclined lower surface and is discharged from the lower end thereof and collected.  The conduit in the pre-ferred embodiments is flat and transparent and the spacing between the upper and lower walls of the conduit is selected so that only a small part of the solar energy is absorbed in the conduit while the fluid in the conduit recovers a substantial part of the released heat of condensation.  In accordance with the invention, more fluid is circulated in the conduit means than the quantity of liquid evaporated from the distillation compartments and condensed on the conduit means in order to carry away the released heat of condensation while maintaining the temperature of the fluid below that of the condensing liquid vapor.  In accordance with the preferred embodiments; salt water is distilled and the quantity of fluid circulated through the conduit to absorb and carry the heat of condensation released by the condensing water vapor, will greatly exceed, for example, by 10 times, the quantity of condensed water evapor-ated, and distilled by the apparatus.  Much more fluid is circulated in the conduit to maintain the fluid temperature below that of the condensing water vapor.  The concentrated brine at for instance 80°C may be recycled one or several times in separate distillation units or in distillation channels or compartments of the same unit wherein brine instead of preheated water to be distilled is introduced into the distillation compartments.  Thus, the heat of the brine may be recovered and the concentration of the brine may be increased in successive compartments and units, allowing a more economical extraction of salts from the brine.  A separate heat exchanger using a fluid heated for instance to 150°C by solar energy in a separate solar energy unit can be used to preheat the water to be distilled, increasing its temperature to for instance 75°C before introducing the water into the distillation compartment.  The production of dis-tilled water according to the invention is substantially higher than by conventional solar ponds and the cost of producing distilled water reduced to zero in certain locations when credit is obtained for the salts extracted from the concentrated brine.  Preferably, the bottoms of the distilla-tion compartments are blackened by a water-proof flexible material such as Esso Butyl or a similar material.

Abstract: ABSTRACT OF THE DISCLOSURE     A connector for electrodes in the form of an electrode clip is provided herein which is formed of resilient plastic material, e.g., polypropylene.  It includes a fixed jaw and a movable jaw, the jaws being provided with cooperating female electrical contacts.  An opera-ting mechanism is provided which is composed of a plurality of elements interconnected together by at least two living hinges, one of which being secured to the movable such jaw, and the other interconnecting two opera-ting members but preferably having at least three living hinges, one of the living hinges being integrally secured to the movable such jaw, with the other two living hinges interconnecting three operating members.  The operating mechanism includes an operating lever which is movable to urge one jaw towards the other jaw, and thus to urge the jaws into a closed position.  This action simultaneously forces a preselected one of the living hinges to an over-toggle position to lock the jaws in such closed position.  This electrode clip can be easily manipulated with one hand to secure the connector to the electrode stud which is disposed, e.g., on a human body, to a lead cable, e.g., of an electrocardiograph, without any pressure being applied directly to the stud and hence transmitted to the human body.

A pressure roller is biased into rotating engagement with the feed roller for flexible sheet material to drivingly pass therebetween with the pressure roller having at least one resiliently deformable segment that is eccentric to the pressure roller axis to pick up the leading free end of sheet material on a full roll and lead it into the nip between the feed roller and pressure roller, this pressure roller also has axially spaced conical resilient portions along the length thereof with the conical portions facing from the opposite ends of the pressure roll inwardly toward the mid-point of the pressure roll to promote spreading out the sheet material passing between the feed roller and the pressure roller. A serrated cutting knife is pivotally mounted within the feed roller to sever the sheet material, the serrations on the knife being spaced to accommodate therebetween the deformable eccentric segment and the conical portions on the pressure roller during initial projection of the knife from within the feed roller in severing the sheet material. The cutting knife swings about an axis laterally displaced from the plane of a radially outward portion of the knife and cam followers are carried by the ends of the knife extending beyond the ends of the feed roller with the followers displaced from the pivot mounting axis of the knife. Stationary cams are mounted adjacent the ends of the feed roller with which the cam followers on the knife edge engage to positively project the knife cutting edge beyond the feed roller periphery and retract the cutting edge upon rotation of the feed roller.
