23,256. Metcalfe, J., and Forrester, T. Nov. 18. Corking.-Relates to corking-machines for bottles containing beverages &c. The movable parts of the machine are operated synchronously by cams &c. on the shaft e, which is driven from the main shaft d. The bottles are placed in the sockets c on the revoluble table c, mounted on the pedestal b, the hub m of the table being formed with teeth or projections m, which are engaged by the tappet l on the shaft e, to bring the bottles successively under the corking-plunger o'. The spring-controlled detent n is adapted to engage in the recesses c in the table, to lock the latter in position during the corking operation. The table is also formed with inclined surfaces c , on which the detent bears when released from the recesses c' by the projection e' on the gear-wheel e', the detent thus serving as a brake, to steady the table during its rotation. The bottles are raised into position for corking, independently of differences in their lengths, by the plunger f, which is actuated for this purpose by the weighted lever g or a spring, the downward movement of the plunger for releasing the bottles being effected by the cam h engaging a bowl on the plunger. During corking, the plunger is locked by the wedges i, which are carried by the sliding block i and engage behind the double-ended pawls k pivoted on the lever g. The cam j releases the wedges before the plunger f is lowered. Thecorking-plunger is carried by the vertically-reciprocated slide o, which is actuated through the rod q by the crank q on the cam j. The slot o in the slide actuates the cork-feeding shuttle p , which conveys the corks from the tube o to the corking-plunger in a known manner. The corks may be delivered to the tube o by hand, or, automatically, from the tubular magazine o , Fig. 4, in which the delivery is controlled by the pivoted trigger r having a pin r' on each end. The trigger is normally held by the spring r in the position shown, the corks resting on the lower pin r'. To release the lowest cork, the trigger is rocked so that the upper pin r enters the magazine and the lower pin is retracted therefrom. The operation of the trigger may be effected by the arm s on the slide o.
Abstract:
A method and system referred to as PALM (Patterning by Adhesive of Large Relief Three- Dimensional Micro structures) with large reliefs exceeding 1 µm and being as large as 100 µm. The Micro structures can be either deterministic (such as micro prisms), or random (such as diffusers), the first obtained by copying an original super master, and latter obtained by copying a laser speckle pattern. The master process entails copying a super master into the form of the micro structure constituting a pattern on the patterning cylinder (called a drum), to be then continuously multiplied in the PALM system, in a continuous roll-to-roll web process. The latter method, together with the related system, is the subject of this invention. The rolls continuously repeat the master pattern, copying by adhesive with large viscosity on acrylic (hybrid) as well as by a monolithic process. The monolithic process can be accomplished using temperature and pressure, or by UV-cured polymerization. Therefore, the invention comprises three alternative processes: one, hybrid (adhesive on acrylic), and two monolithic ones. In the PALM (hybrid) process, an epoxy is wet-coated on film substrates such as polycarbonate (PC), polyester (PET), (PE), or other flexible material. The adhesive, in liquid form, is applied to the substrate by a self-metered coating sub-process. In the present invention, the adhesive is used for forming the micro structure pattern. The micro structure pattern is replicated from a master roll or image drum onto a coating roll.
