Abstract: A rocker arm cover providing diagnosis and repair access to the rocker arm while the engine is running. The rocker arm is also capable of protecting a rocker arm from contacting other components of the engine, reducing contamination, and inhibiting oil and fluids from dispersing. The casing includes a multiplicity of access holes positioned along the casing, and positioned for accessing the rocker arm. A plurality of removable caps and joining mechanisms cover the access holes. Upon removal of the caps and joining mechanisms, a listening device with a diaphragm may be utilized to listen for specific rattling sounds associated with a loose rocker arm, or other valve in the cam system. After this diagnosis, a fastening device may be utilized to engage and adjust the rocker arm, rocker arm fasteners, or the intake and exhaust valves linked to the rocker arm.

Abstract: The present invention describes a method for producing multifunctional materials comprising the steps of: a) chemically activating functional groups present in a micro- or nanoparticulate base material; b) performing a nucleophilic substitution reaction between at least one terminal amino, carboxyl or thiol group of a PNA or DNA type A chain and at least one activated functional group of the base material produced in step (a); c) conjugating to a biomolecule by means of chemically activating functional groups of a PNA/DNA type B chain, which is complementary to the PNA/DNA type A chain; and d) hybridizing the PNA/DNA type A chains which are bound to the base material according to step b) and the PNA/DNA type B chains having biomolecules bound thereto according to step c) by means of PNA-PNA or PNA-DNA molecular recognition.

Abstract: Phenolic resins and processes of making these phenolic resins that are useful for making binders for mineral wool insulation products are disclosed. The addition of a boron salt early in the process of making these phenolic resins leads to enhanced properties such as a reduction in the amount of tetradimers and an improvement in the stability of both the base resin and the pre-react.

Abstract: The invention relates to a process for producing non-CFC resol foams of low density using perfluorinated ethers along with a HCFC or CFC blowing agent, and to foams produced by such a process. The process generally comprises: (a) forming a mixture by combining a resol resin with a blowing-agent blend comprising (i) at least one blowing agent selected from the group consisting of hydrogenated chlorofluorocarbons and hydrogenated fluorocarbons and (ii) at least one perfluoroether additive selected from the group consisting of peiurinated ethers; (b) adding an acid catalyst to the mixture to initiate foaming and form a foam; and (c) curing the foam to form a cured foam that is essentially free of CFCs.

Abstract: This invention relates to the production of low density resol foams from resol resins. The foams have a density of 2.0 pounds per cubic foot or less and are produced with a blowing agent of low boiling point HCFCs and perfluoroalkane.

Abstract: A phenol-formaldehyde resol to which urea has been added is mixed with a boric acid-hydroxyl-amide component to provide high temperature resistant binder compositions for use in the manufacture of thermally stable bonded mineral fibre insulation structures.

Abstract: This specification discloses ecologically desirable, improved binder compositions suitable for bonding fibers. These binders exhibit low pollutant characteristics and improved properties, due to a combination into the binder of aminoplast resins or non phenolic monomeric materials capable of co-condensing with formaldehyde, together with a substantially phenol free, low mono methylolphenol high ortho para di methylol phenol content, water soluble thermosetting phenol formaldehyde resole solution. The phenolic resole resin is made to conform to the desired composition by mixing together a high mole ratio of formaldehyde with phenol and calcium hydroxide with cooling so that very little reaction takes place. The reaction is then allowed to proceed according to a carefully controlled temperature-time cycle without external heat input until substantially all the phenol has reacted to form condensation products and yet the mixture is still infinitely dilutable with water.
