  • Patent number: 8574452
    Abstract: A heat dissipation composition includes a hydroxy function group contained double-bond substance (such as 2-hydroxybenzophenone, 2-hydroxydibenzoacid, and alkyl 2-cyano-3,3-diphenylacrylate) formed of aromatic hydrocarbons having precursor of benzene, which is mixed with a resin-based coating agent and a diluting agent at predetermined ratios for application on a surface of a heat dissipater to facilitate heat dissipation, whereby when the heat dissipater receives heat to be dissipated, the double-bond substance absorbs the heat and induces displacement to form a resonance structure so as to more efficiently dissipate the heat and when the heat is dissipated, the substance restores the double-bond condition thereby realizing improvement of efficiency of heat dissipation.

  • Patent number: 4487707
    Abstract: A stop leak composition for sealing leaks in refrigeration systems and method for using same. A mixture of smooth surfaced particles having a size small relative to the leak size is suspended in refrigeration oil and injected into the refrigerant circuit of a system. The particles will be forced into small leaks and will agglomerate to seal the leak. Graphite particles and Teflon.RTM. particles in size ranges from 20 microns to 65 mesh are suitable.

  • Patent number: 4256158
    Abstract: A pneumatic tire having, between two vulcanized elastomeric partitions, a layer of a sealing mixture arranged on the inner wall of the cavity of the tire, at least below the crown and from one shoulder to the other, is improved due to the fact that the layer of sealing mixture has a base of at least one vulcanizable elastomer of low molecular weight, preferably less than 30,000, contains at least one component of a vulcanization system for the vulcanizable elastomer and has an apparent viscosity of between 10.sup.3 and 10.sup.7 N/s/m.sup.2 at 60.degree. Celsius measured with a Weissenberg rheogoniometer at a shear velocity gradient of 10.sup.-2 to 10.degree.s.sup.31 1 ; at least one other component which forms the vulcanization system with the component contained in the sealing mixture being contained in a dispersion within the cavity of the tire.

  • Patent number: 4239076
    Abstract: A tire whose inner wall is provided, below the crown of the tire and at least from one shoulder to the other of the tread, with a lining containing at least one means for sealing puncture holes is improved due to the fact that the lining comprises at least one layer of a vulcanizable sealing mixture separated by a vulcanized elastomeric partition from at least one layer of a vulcanizing mixture capable of vulcanizing the vulcanizable sealing mixture, each of the layers containing between 20% and 100% by weight of an elastomer of low molecular weight, preferably less than 30,000.

  • Patent number: 4237952
    Abstract: A pneumatic tire whose inner wall is provided beneath the crown with a lining which extends at least from one shoulder to the other of the tread and comprises a layer of a sealing mixture capable of flowing into a puncture hole, the layer being covered radially inward by a vulcanized elastomeric partition, is improved due to the fact that the layer of sealing mixture has a base of at least one elastomer of low molecular weight, preferably less than 30,000, mixed with at least one thermosetting resin, and due to the fact that at least one cross-linking agent or hardener for the thermosetting resin is isolated from the layer of sealing mixture by means of a vulcanized elastomeric partition arraged radially inward of the layer of sealing mixture.

  • Patent number: 4238638
    Abstract: An electric cable having a core made of insulated conductors disposed within a polymeric sheath. Voids within the core, between the conductors, are at least partially filled in the unused cable with a mixture comprising untreated calcium carbonate and a water-attracting polymer able to form a gel on contact with water without swelling. The cables are made waterproof by the presence of the mixture, which is cheaper than prior mixtures but as effective.
