Title: Process for the production of heat-activatable mats free from supports and release agents and their use for bonding various substrates
Inventor: NEBE VOLKER
IPC: D04H1/56
Filed: 1994-06-03
Abstract: A PROCESS FOR THE PRODUCTION OF HEAT-ACTIVATABLE MATS FREE FROM SUPPORTS AND RELEASE AGENTS AND THEIR USE FOR BONDING VARIOUS SUBSTRATES                 A b s t r a c t The invention relates to a process for the produc-tion of heat-activatable mats based on hydroxyl polyester polyurethanes which are free from supports and release agents and which have viscosities of 600 to 3500 mPa.s, measured as solution viscosity in methyl ethyl ketone (15% Brookfield LVT viscosimeter, spindle 3, 60 r.p.m., 23°C) and weights per unit area of 5 to 200 g/m2, charac-terized in that the mats are produced by melt blowing (for example REICOFIL? melt blowing process)  at melt temperatures in the range from 230 to 260°C using a receiving conveyor belt of which the constituent material has a surface tension of 18.5x10-5 N/cm to 46x10-5 N/cm.     The mats produced by the process according to the invention  can  be wound  into  rolls  without  blocking despite the absence of release agents or spacers and are eminently suitable for bonding various substrates.
Patent CA-2129393-A1 (CA)
Inventor: DEROSA MARC S
IPC: B32B11/04
Filed: 1994-08-03
Abstract: ABSTRACT      An exemplary method for measuring the impact resistance of polymeric film-based laminates involves a falling dart test using laminates that are essentially fully adhered to an inclined mortar block in emulation of stone impacts in backfill situations. Methods for protecting subgrade vertical walls from stone impacts in backfill operations involve the use of a four-layer laminate having an impact energy of at least 50 lb-ft2/sec2 in accordance with a falling dart test using a mortar block inclined at an angle of 60° from vertical. The film-based laminate, comprising a center film having a Young's modulus of at least 200,000 psi (ASTM D 882), is surprisingly discovered to have synergistic properties to provide an average impact energy, as determined in accordance with the 60° impact test, which far exceeds the additive impact energy of the components and which reflects more accurately the performance of the laminate in the actual backfill situation

Title: Coated article for hot hydrocarbon fluid and method of preventing fuel thermal degradation deposits
Inventor: COFFINBERRY GEORGE A
IPC: F02C7/224
Filed: 1994-09-15
Abstract: ABSTRACT OF THE DISCLOSURE      Articles for hot hydrocarbon fluid wherein the surface for contacting the fluid is a diffusion barrier material or a catalytic material coated on a metal substrate.  The material is either catalytically-inactive tantalum oxide which inhibits the formation of coke in the fluid or catalytically-active zirconium oxide which promotes the formation of a loosely adherent coke in the fluid while inhibiting the formation of gum in the fluid.          The coating materials, i.e., the diffusion barrier coating material and the catalytic coating material, are deposited by chemical vapor deposition (CVD), e.g., by effusive chemical vapor deposition of an organometallic compound on the surface without the use of carrier gas, without pre-oxidation of the surface and without thermal decomposition of the diffusion barrier material or the catalytic coating material.  The articles having the coated surface  find utility in components subjected to high temperatures wherein the components are in contact with hydrocarbon fluids without additives, without special attention to quality control and without the need for special processing.

The flow rate of material may be measured in a sec-ond chamber (34) having another outlet (37) through which the material flow also passes: The flow rate measurement outlet may be in the form of a slot (37).  Flow rate is determined by reference to the height (h2) of material flow through the slot. Bulk density may be determined by maintaining a constant volume of ma-terial in the chamber with the particle size measurement outlet, and by refer-ence to changes in the weight (31b) of the contents of this chamber.

Filed: 1993-05-28
Abstract: A method and apparatus for continuously extruding a product, and forming it into a bend by applying a force (20) to it at a point of application downstream of where its surface becomes solid. The force has a transverse component relative to the die axis (18), and performs work upon the extruded material (5), extra to the work that has already been performed to extrude it. Non-contact means of applying the force are described, and various ram-type contacting means (33) are illustrated. Alternative means of operation are described in which the point of application of the force to the extrudate during bending varies relative both to the extrudate and to the die (4), relative to the extrudate only, and relative to the die only. Means to alter the direction of bending are described, and to diminish the necessary bending force by creating a fluctuating melt pressure within the die.
