Abstract: ABSTRACT            A method and apparatus for granting selected access to material such  as  data  and  databases,  messages  and other  textual information, graphs, tables, maps, facsimiles (FAX) of all manner of transmitted materials, audio such as speech and music, video, images,  and photographs,  provided on storage media utilizing information encoded in the storage media.  The storage media are included  in  one  or  more  reading  devices  associated  with  a computer.  A storage accessing device, such as a smart card, is used in conjunction with the computer to determine whether access to a particular user to specific storage media is granted.  The storage media can be sub-divided into a plurality of logical zones and access to all or a portion of the material on the storage media is granted based upon the logical zones to which the user is allowed access.  Information provided on the storage media  would  include  an  index  table  listing  the  security identification code, the logical zones to which a particular user is  assigned  as  well  as  a  personal  security  key  used  in conjunction with a personal security key provided in the smart card.   The  interaction between the user's personal accessing device  and  the  index  table  provided  on  the  storage  media determine  if access is granted as well as access privileges accorded to the user.

Abstract: An article having a substrate with a synthetic resin surface that has an affinity for printing inks is printed with a laser-induced hot print method. A transfer medium, printed on a face side with an image formed of sublimable dyes is faced against the synthetic resin surface, and a laser beam is made to impinge upon the unprinted back of the transfer medium. The laser beam is of sufficient intensity to cause the dyes to sublimate and penetrate at least partially into the synthetic resin surface of the substrate.

Abstract: A membrane distillation module is provided with a thin, flexible microporous P.T.F.E. membrane (16) positioned against an impermeable condensor sheet (12) that is stiffer in bending than the membrane. Distillate vapour diffuses through the membrane from a hot feed flowing rapidly past the membrane, and condenses and collects between, and in intimate contact with, the membrane and the condensor sheet. The condensed distillate is stripped by forces exerted by the hot feed acting on the distillate across the membrane, and flows toward a distillate outlet (40) located in the downstream direction of the hot feed flow. Cold feed flows past the condensor sheet in the counter direction to that of the hot feed.

Abstract: A process is dislosed for rejecting nitrogen from a natural gas feed containing nitrogen over a wide range of composi- tions, e.g. 5-85% nitrogen by volume, under elevated pressure using a single distillation column and a closed loop methane heat pump which reboils and refluxes the column. An intermediate reflux condenser is refrigerated by both the heat pump and overhead nitrogen fraction from the distillation column. The process can handle feeds with increasing nitrogen content and more than 100 ppmv carbon dioxide. The feed can be at pipeline pressure with the natural gas liquid components still present or at lower pressure with natural gas liquids removed. A mixed cryogenic refrigerant can be used in the heat pump as an alternative to methane. The process provides a high methane recovery over the entire feed range, and provides a nitrogen product stream having an elevated pressure suitable for recycling and reinjection to an oil or gas well to improve well head pressure.

Abstract: It has been found that monovinylidene aromatic/conjugated diene/ethylenically unsaturated acid copolymer compositions are provided with good combinations of physical properties when a sulfoalkyl monomer is employed in minor amounts in such polymer in place of emulsifying additive(s). In particular, the combinations of wet and dry pick resistance have been shown to be maintained or improved when paper coating formulations are prepared from latex polymer compositions according to this invention. Sulfoalkyl (meth)acrylate salts and 2-acrylamido-2-methylpropane sulfonic acid salts are shown to be suitable sulfoalkyl monomers for this purpose.

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 organometallic 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 prepolymerization 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 particularly ethylene with a narrow molecular weight distribution. The problem has in the present invention been solved by forming the particles by spray-crystallizing a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol and by using titanium (IV) alkoxyhalide 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 sensitive procatalyst having a better molecular weight selectivity. The invention also relates to the specific use of the procatalyst 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 polymerization is combined with the organometallic compound of aluminium or some other metal acting as cocatalyst

Abstract: A dither drive system for a ring laser gyroscope includes a computer, a digital to analog converter, a filter and a power amplifier. The system also includes a frame mounted to a flexure having a resonant frequency, the flexure being mounted between a base and the frame such that the frame may be dithered relative to the base.      The dither frequency is sensed and a digital signal that corresponds to a specified dither drive signal is produced.      The digital signal is converted to a corresponding analog signal and the dither drive signal is toggled to drive the flexure at its resonant frequency. This system avoids the necessity of using much of the expensive hardware included in previous systems.

Abstract: ABSTRACT OF THE DISCLOSURE    The analog signals from the reading means and the plural number of detecting means provided in the facsimile communication apparatus of the invention are selected sequentially by the selective connecting means for connection to the analog/digital conversion means and converted into digital signals.  This eliminates the necessity of connecting individual analog/digital conversion means to the reading means and the plural number of detecting means and enables miniaturization of the apparatus construction by reducing the number of parts used.          Moreover, the miniaturization of the construction can be further promoted because of the fact that the parts reduced are the parts for processing analog signals.
