Title: Method for producing a sealed package, cut blank for the production of the package and produced package
Inventor: KRAJNOVIC RADOVAN
IPC: B65D3/22
Filed: 1991-04-17
Abstract: ABSTRACT           A  perforation  (11)  is  made next  to  at least one joining edge (42) in a basic layer (1).  A plastic film (2)  is then applied to at least one side of the base layer (1), covering the perforation (1).   A cut-out is made from the package material (3) so obtained.  The cut-out has at least one film tab which juts out next to at least one joining edge (42) and which previously formed the portion (21) of the film placed over the perforation.   A joining edge (42) on the inside or outside of the package is then covered and sealed by this film tab.  The basic layer  is  preferably  paper  or  cardboard  and  can therefore be simply and attractively printed.   If the basic layer (1) is enclosed between two plastic films (2), the two films can be united in all film tabs.  The joining edges are then already completely enclosed on  the  cut-out.   Very  strong,  flat  and tightly sealed joins can be obtained.  Webs, sheets or cut-outs of packaging material for finishing the package can be supplied during filling.

Title: Image generator
Inventor: BAKER STEPHEN JOHN
IPC: G09B9/32
Filed: 1991-06-03
Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus for simulating the illumination effects of a vehicle mounted light source in an image displayed on a screen.  The image is intended to represent the appearance of a model defined in a database in world space coordinates from an eyepoint position in world space, the model being defined in terms of a plurality of features each having predetermined attributes. The vehicle mounted light source is defined in terms of an origin and a direction in eyepoint space.  For each feature potentially contributing to the image, the angular position of a point on that feature relative to the light source is calculated as the angle between the light source direction and a line drawn to that point from the light source.  An illumination intensity for that point is determined by reference to the calculated angle, and the illumination intensity is reduced as a function of the distance from the eyepoint to the said point to provide a resultant intensity.  The attributes of the feature at the said point are modulated as a function of the resultant intensity.

Title: Method of doping porous glass preforms
Inventor: BERKEY GEORGE E
IPC: C03B37/014
Filed: 1992-12-01
Abstract: Abstract of the Disclosure Disclosed is a method of forming a doped glass article.  Heated glass particles are deposited on a mandrel where they adhere together to form a porous glass preform having interconnective pores.  The mandrel is removed to form a tubular preform having an axial aperture.  The preform is suspended in a consolidation furnace by a gas conducting handle having a dopant containing chamber.  As the handle and preform are heated, there is flowed through the chamber a gas that reacts with the heated dopant to form a reactant gas that flows into the aperture and into pores, whereby a dopant is incorporated into the porous glass preform.  The doped preform is heat treated to consolidate it into an elongated non-porous glass body containing the dopant.  The glass body can be provided with cladding glass and drawn into an optical fiber.

Title: Apparatus, insert and method for forming curing envelope
Inventor: KASSAW CALVIN M JR
IPC: B29C43/10
Filed: 1993-01-20
Abstract: An apparatus and method for forming curing envelopes which apparatus and method enable the use of a conventional inner tube mold for making a curing envelope preform in the form of an envelope tube which may have a portion thereof easily removed to provide a curing envelope suitable for use in a tire retreading process. A curing envelope is made by placing an annular tube of uncured envelope material in a curing mold having a center core and a mold insert installed therein. The insert includes a pair of coaxial annular rings projecting radially outwardly from the center core and connecting straps for maintaining the axial spacing between the rings. The mold is closed and heat and internal pressure are applied to the envelope tube for curing the envelope tube and urging the tube against the interior cavity surface with the annular rings penetrating into the inner wall of the tube for forming therein corresponding annular grooves. The mold is then opened and the envelope tube is removed from the mold after which the envelope tube is severed along the annular grooves to remove the portion of the inner wall of the envelope tube between the grooves thereby to form a curing envelope of generally U-shape cross-section.

Inventor: FISCHER ADDISON M
IPC: G06Q10/10
Filed: 1993-03-31
Abstract: A method and apparatus for creating, supporting and using a travelling program is disclosed. A "travelling program" is a digital data structure which includes a sequence of instructions and associated data and which has the capability of determining at least one next destination or recipient for receiving the travelling program and for transmitting itself together with all relevant data determined by the program to the next recipient or destination. The travelling program can compute, according to any algorithm whatsoever, the digital material which is to be signed, and also, as needed, the digital material which is to be verified. The present invention also allows the program to conditionally decide, based on any known criteria, which users should participate in the signature process. The present invention also allows use of digital signatures to allow the travelling program to provide other types of valuable authentication. For example, as a security convenience the present invention allows for the digital signature authentication of the entire transmission from one user to another. This includes the travelling program itself, its variables, and any ancillary data or files. The present invention provides a unique mechanism for automating data collection among a group of users.      The travelling program may be sent to one user, attach (or detach) relevant data files and move on to the next user. Data or files, collected from one or more users can be deposited with another user, or accumulated for hatched processing as desired.      This methodology eliminates the need for individual users to be counted on to transmit all the required data in the required format. The present invention also efficiently performs electronic document interchange (EDI) in the context of a travelling program which sends itself from user to the next within an organization, collecting, editing and approving data.
