Abstract: METHOD OF CUSTOM FITTING EYEGLASS FRAMES        AND ARTICLE FORMED THEREBY                ABSTRACT OF THE DISCLOSURE           A method of custom fitting eyeglass frames to the nose of a wearer, which is in part performed by an optician or the like and in part performed by an eyeglass frames laboratory.          The optician or the like heats a preferably horseshoe shaped wax wafer until it is moldable, then positions such on the bridge area of the wearer's nose and applies pressure thereto, bending the wafer concavely to conform its shape to that of the bridge of the nose.  The eyeglass frames are then situated against the convex surface of the wafer in their normal viewing position and an imprint of the nose bridge portion of the frames is made on the outer surface of the wax wafer.  Finally, the wax pattern thus formed is removed from the frames and wearer's nose and cooled to fix its shape, and the outline of eyeglass frames bridge is drawn thereon.  The resulting wax pattern is then sent to an eyeglass frames laboratory and a plastic nosepiece is there fabricated by a two-step dental stone casting procedure, which renders the plastic nosepiece a precise replica of the wax pattern.  The finished plastic nosepiece is returned to the optician for attachment to the eyeglass frames.  With this nosepiece in position on the bridge of the wearer's nose, the optician performs the final adjustment with the eyeglass frames in the normal viewing orientation, and a quick setting adhesive or the like is used to attach the finished nosepiece to the bridge portion of the eyeglass frames.

Abstract: ABSTRACT OF THE DISCLOSURE A composite pressure sensitive adhesive construction contains a central release liner, a lay-er of an adhesive on each side thereof, and an exter-ior release liner on at least one of the adhesive layers.  The central release liner and the exterior release liner contain release coatings on surfaces thereof which contact the adhesive layer. The compos-ite construction may be made up in the form of a roll for easy dispensing or in the form of a precut tape. The pressure sensitive adhesive construction is gener-ally useful for making any type of sealing connection wherein an initial releasable connection is desired. For example, the pressure sensitive adhesive construc-tion may be utilized in sealing pipe insulating jack-ets wherein the exterior release liners are removed and the adhesive construction is applied to the oppo-site longitudinal ends or sides of the insulating jacket cover. The insulating jacket may then be stored until utilized whereupon the central release liner is removed, the jacket inserted about the pipe, and a sealing connection then made by pressing the two ex-posed adhesive layers together. Alternatively, the adhesive may be applied through rolling, spraying, or painting directly to both opposite longitudinal ends or sides of the jacket cover, the two applied adhesive layers being separated by the interposition of the central release liner during storage.

Abstract: ABSTRACT OF THE DISCLOSURE    A switch, that appears the same as an ordinary snap switch, is shown with a positive ON and a positive OFF with a variable control circuit therebetween.  The variable control circuit includes a triac gated through a diac to give an infinite control range that depends upon the point at which the triac is triggered.  In using the variable control circuit of the switch, a shunt or a bypass is provided for the gate of the triac through a full wave bridge rectifier circuit for a predetermined time interval.         The time interval is determined by an RC time constant connected across the bridge.  Therefore, for the afore-mentioned predetermined time interval, essentially a full wave AC voltage is passed through the triac to a load.  For motors, this allows the motor to come up to speed prior to subsequently reducing the speed of the motor by the variable control circuit after the predetermined time interval.

Abstract: A B S T R A C T     Processes for manufacturing a metal-plastic composite foil having a plastic core covered on both sides with an outer layer of thin metal strip, in particular aluminum thin strip are already known.            However, the use of a so-called triplex composite of the kind just mentioned for relatively large volume containers of full weight up to about 30 kg has been very limited be-cause of the unsatisfactory deep drawing properties of such composites in deep drawing or deep drawing by elongation of the foil (stretching).            By means of the invention a process for manufacturing a metal-plastic composite (1,10 and 20) of the so-called triplex composite kind and a metal-plastic composite foil made by this said process have been developed which allow in particular the manufacture of semi-rigid light-weight containers which have a weight of up to ca. 30 kg when full and this even by cold forming. Containers made from such composite foils are particularly resistant to break-age or leakage and can be closed or fitted together by known sealing methods.     (Fig. 1)

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates generally to fluidized catalytic cracking. More particularly, the present invention relates to a baffle arrangement that improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit.  The catalytic re-actor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel.  An inlet riser conduit forming a primary reaction zone extends generally within the shell from the lower end of the vessel to a location near the top of the vessel. A shroud surrounds the upper end of the riser conduit and forms an annular outlet for downwardly discharging a mixture of hydro-carbon and catalyst.  According to the present inven-tion, an annular catalyst disengaging riser baffle for deflecting the mixture from the outlet toward the wall of the vessel in arranged on the outside of the riser conduit below the annular outlet above the strip-ping zone.  Still further, in the preferred embodiment an annular catalyst disengaging wall baffle is arranged on the inside of the shell for again deflecting the mixture, now mostly catalyst, generally downwardly and toward stripping the zone of the vessel. Preferably, the riser baffle and the wall baffle are arranged with-in the shell such that the baffles in concert with the annular discharge outlet form a partial cyclone separating zone between the baffles to thereby improve the separation of hydrocarbon vapors from the catalyst.  This cyclone action promotes early disengagement of hydrocarbon vapor from the catalyst and reduces undesirable catalyst carryover in the vapor to conventional cyclones through which the hydrocarbon to conventional cyclones through which the hydrocarbon products are recovered.  At the same time, stripping efficiency is also increased by quickly and effectively delivering spent catalyst to the stripping zone and undesirable secondary cracking reactions in the dilute phase are minimized by lowering the concentration of spent catalyst in the dilute phase.
