Abstract: An engine cooling system has an engine water jacket, a coolant circulation passage connecting a water jacket outlet to a water jacket inlet and a radiator disposed in the coolant circulation passage. A thermostat valve selectively closes and opens the coolant circulation passage leading to the radiator. A bypass passage extends from between the water jacket outlet and the thermostat valve to an outlet side of the radiator. A bridge passage connects a portion of the bypass passage to a portion of the coolant circulation passage located downstream of the radiator and upstream of where the bypass passage merges therewith. A resistance generating section is located downstream of the bridge passage connection to the coolant circulation passage and upstream of the bypass passage connection to the coolant circulation passage. The bridge passage has an oil heat exchanger to exchange heat between the cooling medium and transmission oil passing therethrough.

Abstract: Novel cyclohexenone derivatives, which are shown by the general formula ##STR1## wherein each of R.sup.1 and R.sup.2 represents a hydrogen atom, lower alkyl or phenyl group; one of R.sup.3 and R.sup.4 represents a hydrogen atom or lower alkyl group, and the other represents an unsubstituted or substituted phenyl, lower alkyl or aralkyl group, or R.sup.3 and R.sup.4, taken together with the adjacent nitrogen atom, form a 5 to 6-membered heterocyclic ring; one of R.sup.5 and R.sup.6 represents a hydrogen atom or lower alkyl group, and the other represents a lower alkyl, phenyl or aralkyl group, or R.sup.5 and R.sup.6, taken together with the adjacent nitrogen atom, form an unsubstituted or substituted 5 to 6-membered heterocyclic ring, and their pharmaceutically acceptable salts, useful medicines such as analgesics.
