Title: ETHYLENE-'alpha'-OLEFIN/DIOLEFIN POLYMER SOLUTION POLYMERIZATION PROCESS.
Inventor: SCHIFFINO RINALDO SORIA
IPC: C08F210/16
Filed: 1996-04-19
Abstract: This invention is a solution process for the preparation of ethylene-'alpha'-olefin/diolefin copolymers comprising contacting ethylene, one or more 'alpha'-olefin monomer, and optionally one or more diene monomer, with a catalyst system containing a catalyst activator and a Group 4 metallocene compound, comprising a) conducting the polymerization reaction at a temperature of about 60 to 150 degree C; b) selecting as the Group 4 metallocene compound one or more members of the group consisting of cyclic monocyclopentadienyl Group 4 metal and covalently bridged (bis) indenyl hafnium metallocene compounds; and c) maintaining the 'alpha'-olefin concentration at a molar ratio to that of ethylene of between about 0.3 to 7.0 and a diolefin to ethylene molar ratio of between about 0.01 and 0.4. In a preferred embodiment the process comprises: 1) mixing with a reaction solvent the one or more 'alpha'-olefin monomer, the optional one or more diene monomer, and the catalyst activator, either together or separately, thereafter 2) mixing with the reaction solvent an effective scavenging compound prior to or with introduction of the unactivated Group 4 metallocene compound under conditions such that the scavenging compound is in contact with the activator compound for a period of time not exceeding about 1 minute, and 3) contacting the activator compound with the unactivated Group 4 metallocene compound in the presence of said monomers. The process can be advantageously practiced at a reaction temperature of at least 60 degree C, preferably above 80 degree C, most preferably above 110 degree C, to achieve high number average molecular weight polymer having high 'alpha'-olefin monomer and diene monomer contents with high diene conversion rates. The process is particularly suitable for the preparation of elastomeric ethylene-propylene or ethylene-propylene-diene monomer elastomers.

Patent MX-9709948-A (MX)
Title: Composite gasket comprising surface formed tangs.
Inventor: TENSOR PAUL M
IPC: F16J15/12
Filed: 1997-12-09
Abstract: A composite gasket including facing material and a core material. The core material includes tanged portions which are formed by disturbing a surface of the core. The tang portions preferably terminate into pointed tips which penetrate the facing material when it is forced aginst the tangs. When sufficient force is applied agains the facing material, the pointed tips of the tangs deform inwardly forming hook shaped ends. These hook shaped end help form and maintain an excellent mechanical bond between the core material and the facing material. The forming of the tangs does not penetrate completely through the thickness of the core material but simply forms a slight divot in the surface of the core material. Thus, there is no possibility of leakage through the core material.

Title: Single-ply imprintable receipt and method of imprinting a receipt.
Inventor: MCCORMICK JOSEPH A
IPC: B41L1/28
Filed: 1997-12-19
Abstract: An apparatus and method is provided for imprinting duplicate copies of a credit card receipt using a single-ply roll of paper. The paper can be either coated on a first side with a carbonless coating that contains rupturable microcapsules, each filled with reactive, colorless dyes, and coated on a second side with a resin adpated to react with the colorless dyes, or coated on a single side with self-contained microencapsulated colorless dyes and reactive resins. To include transaction information printed on the credit cart receipt as well as information written on the receipt by the customer (such as a signature and an indication of the amount of any gratuity), the transaction information is substantially duplicated in two separate fields each on a separate portion of the credit card receipt. At least part of the two separate portions are then aligned and presented to the customer for completion. The two separate portions can be aligned by either folding the credit card receipt along a printed or imaginary line between the two separate portions, or by separating the two separate portions from one another and stacking the two separate portions one upon the other.

Patent NL-255226-A (NL)
IPC: C07C51/27
Abstract: The invention comprises a solution of dinitrogen tetroxide in a mixture of acetic and nitric acids wherein the molar ratio of acetic to nitric acid is from 0.5 to 3 to 1.  The solution, which may contain up to 15% by weight of water, may be prepared by absorbing N2O4 in the acid mixture by countercurrent contact in a column at atmospheric or superatmospheric pressure, e.g. 100 p.s.i.g.  The acid mixture is preferably a substantially azeotropic mixture. The solution may be used for the oxidation isobutylene to a -hydroxyisobutyric acid (see Division C2). Specifications 785,152, 855,880 and 883,493 are referred to.ALSO:a -Hydroxyisobutyric acid is prepared by oxidising isobutylene with dinitrogen tetroxide in a reaction solvent comprising a mixture of acetic and nitric acids having the dinitrogen tetroxide absorbed therein, wherein the molar ratio of acetic to nitric acids in the reaction solvent is from 0.5 to 3 to 1.  The reaction is carried out at below 40 DEG C., and preferably below 10 DEG C.  The N2O4 may be dissolved in a mixture of acetic and nitric acids and then the isobutylene passed into the resultant solution or, alternatively, the N2O4 may be dissolved in a first mixture of acetic and nitric acids, isobutylene may be dissolved in a second mixture of acetic and nitric acids (thus forming t-butyl acetate and t-butyl nitrate), and the resulting solutions combined. The preferred concentration of N2O4 in the acid mixture is between 20% and 60% by weight although smaller amounts may be used.  Desirably at least one mole and preferably 3 moles of N2O4 is used for each mole of isobutylene.  In addition to a -hydroxyisobutyric acid the oxidation yields a -nitratoisobutyric acid, a -nitratoisobutyraldehyde, a -hydroxyisobutyraldehyde and a -(a -hydroxyisobutyroxy)-isobutyric acid which may be converted to further a -hydroxyisobutyric acid by further oxidation and/or hydrolysis.  Specifications 785,152, 855,880 and 883,493 are referred to.ALSO:A mixture of acetic and nitric acids wherein the molar ratio of acetic to nitric acid is from 0,5 to 3 : 1 is used for separating dinitrogen tetroxide or isobutylene from gases containing them. Dinitrogen tetroxide may be separated from carbon dioxide, carbon monoxide, nitrogen and nitrous oxide while isobutylene may be separated from complex mixtures of hydrocarbon gases containing both saturated and unsaturated hydrocarbons.  In Example 6 isobutylene is separated from a mixture of isobutane, butene-1, isobutylene, butene-2, n-butane, butadiene and trans butene-2 and in Example 8 isobutylene is separated from a mixture of n-butane, isobutane, propane, isobutylene, butene-1 and trans butene-2.

Abstract: In a branched optical fibre network in which an optical signal (I) modulated with a data signal is distributed by a transmitter connected to the network, OTDR based on correlation is applied independently of position by uncoupling both a signal part (I1) of the distributed signal (I) in the forward direction and a signal part (R1) of the reflected signal (R) in the return direction at an arbitrarily chosen uncoupling point P in a fibre connection (46) of the network, detecting them and correlating them with one another. A device for performing such a positionally independent correlation OTDR is provided with uncoupling means (60) having a first signal output (68) and a second signal output (66), via which outputs the signal part (I1) and the signal part (R1), respectively, are fed to optical receivers (70 and 71).
