Title: Pull tab innerseal
Inventor: HAN HAK-RHIM
IPC: B32B15/08
Filed: 1990-05-03
Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to containers, and, in particular, to multi-layer sheet materials for sealing containers. A problem encountered with tabbed innerseals currently used in the marketplace is known as springback.  In most conventional tabbed innerseals, after the tab is folded to allow insertion of the innerseal in the cap, the tab springs back about 90° so that rather than laying flat against the portion of the innerseal covering the mouth of the container, it extends roughly perpendicular to the plane of the innereal.  After the innerseal is inserted into the cap, springback of the tab can push the innerseal out of the cap and cause it to be misaligned during sealing so that an inadequate seal is formed.  Springback of the tab can also cause the innerseal to fall out of the cap, resulting in an unsealed container.  This invention provides a reinforced sheet material suitable for making innerseals and sealing membranes for containers.  The sheet material comprises a layer of sealing material for bonding the sheet to a container, a layer of material substantially impermeable to air and moisture, and a reinforcing layer comprising at least two plies of monoaxially oriented film combined in lamination with the strong direction of at least one ply crossing the weak direction of another ply.  Tabbed innerseals made from the sheet material of this invention exhibit less springback than do tabs of conventional tabbed innerseals.  The invention also includes innerseals and sealing membranes made from the aforementioned sheet material and containers utilizing these innerseals and sealing membranes.

Title: Method for the preparation of catalyst components for the polymerization of ethylene with a relatively narrow molecule weight distribution
Inventor: SORMUNEN PEKKA
IPC: C08F10/00
Filed: 1990-07-13
Abstract: Abstract The invention relates to a method for the preparation of a supported procatalyst intended for the polymerization of olefins, in which particles are formed from magnesium halide and alcohol, the particles are reacted with an organo-metallic compound of any of the metals of the groups I to III, the thus obtained particulate product is activated by means of a titanium(IV) compound, and optionally a prepoly-merization is carried out for the activated particles. A problem with this kind of a method is, how to form particles from magnesium dihalide and alcohol having an advantageous structure for the polymerization of ethylene and particular-ly ethylene with a narrow molecular weight distribution. The problem has in the present invention been solved so that the particles are formed by spray-crystallizing a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol and that titanium(IV) alco-xyhalide has been used as the titanium compound. The catalytic properties of the particles thus obtained are improved, especially after the prepolymerization carried out by means of ethylene, which leads in the polymerization to a still more active, very hydrogen and comonomer sensible procatalyst having a better molecular weight selectivity.            The invention also relates to the specific use of the pro-catalyst prepared by such a method for the polymerization of alpha-olefins. By a procatalyst is meant in this context the catalyst component of the Ziegler-Natta-catalyst which is based on the transition metal and which before the poly-merization is combined with the organometallic compound of aluminium or some other metal acting as a cocatalyst.

Abstract: A video display apparatus includes a video data generator which generates video data of a still picture and a moving picture (graphic data) on the basis of still picture pattern, still picture character code, moving picture character code and etc. programmed in an external storage unit in advance.  A microprocessor applies, in accordance with priority data for the still picture and the moving picture and mode data both programmed in the external storage unit in advance, first priority data to the video data of the still picture character and second priority data to the video data of the moving picture character, respectively.  A priority encoder selects a still picture character or a moving picture character having the highest priority on the basis of the first and second priority data, and applies the number of that character to a decoder.  The decoder outputs a gate control signal in accordance with the number.  In response to the gate control signal, the video data of the character having the highest priority among the respective still picture character and the moving picture character is outputted from a gate.
