  • Patent number: 4450886
    Abstract: A method of producing suction manifolds for automobile engines. In forming an exhaust gas re-circulating pipe passage integrally with a suction manifold for re-circulating exhaust gases from the engine to the suction manifold, a curved pipe of aluminum having a high-temperature resistant film formed on its surface is molded into a manifold of aluminum alloy at a suitable place on the latter.

  • Patent number: 4153400
    Abstract: Rotary pumps wherein the conveyed fluid, e.g. foodstuffs, entering around the rotor seats, is prevented from staying there statically, by circulating part of the fluid from the high-pressure side of the pump chamber to the low-pressure side through appropriate holes or apertures disposed around the rotor seats, and by making use of the fluid pressure itself. Washing can be carried out around the seats by circulating water that is fed to the pump, instead of the fluid, after the use of the pump has been stopped. The pumps feature a fluid circulating passage between the high-pressure side and a space in a cap portion, for purposes of cleaning that space.

  • Patent number: 3966240
    Abstract: Quick-action pipe joint having a pair of clamp members in which tapered groove portions are adapted to engage the peripheries of flanges of the pipes to be connected. The members are curved so as to be able to encircle the pipe flanges, one end of each clamp member being mounted so as to rotate or pivot freely, toward and away from each other. The other ends can be held tightly clamped with a special bolt and a nut arrangement.
