  • Patent number: 7210471
    Abstract: A breather chamber is located in a blow-by gas passage to separate oil from blow-by gas. A partitioning member partitions the interior of the breather chamber into a plurality of spaces. The partitioning member is arranged such that the spaces extend along the flowing direction of the blow-by gas and that an adjacent pair of the spaces are connected at ends in the flowing direction. A separating member is provided in at least one of the spaces. The separating member obstructs the flow of the blow-by gas in the associated space, thereby separating oil from the blow-by gas. Therefore, oil is separated from the blow-by gas securely and is prevented from being brought out of the breather chamber.

  • Patent number: 6659471
    Abstract: A gasket is disclosed, which is adapted for the use in sealing of a tri-face area where a cylinder block, cylinder head and timing-chain housing meet together and come into abutment against one another. With the gasket of this invention, a deposit of bonding agent is applied on an end lug of a solid gasket material to improve the adhesive property and close adherence of the solid gasket material with a fluid gasket material that is filled in the tri-face area. The fluid gasket material charged in the tri-face area is securely fastened to the solid gasket material through the bonding agent. The end lug of the solid gasket material on which the bonding agent is applied is exposed to the tri-face area where both the cylinder head and the cylinder block are cut at their confronting edges to form bevels.

  • Patent number: 4109000
    Abstract: 5-Benzy-2-pyridine carboxylic acids, in which the benzyl group is optionally substituted by one or two like or different alkyl, halo, alkoxy, nitro, amino, acetamido, hydroxy or acetoxy groups, and the corresponding amides and esters, possess dopamine .beta.-hydroxylase inhibitory properties and are useful as blood pressure lowering agents. The compounds, of which 5-(4-chlorobenzyl)-2-pyridine carboxylic acid, 5-(4-hydroxybenzyl)-2-pyridine carboxylic acid and 5-benzyl-2-pyridine carboxylic acid are typical examples, can be prepared by a number of chemical methods.
