Abstract: In a stencil printer system, a stencil is made by the use of master material unrolled from a stencil material roll and is wound around a printing drum by clamping the leading end of the stencil on the printing drum and rotating the printing drum while the stencil is once slackened on the way to the printing drum. There is provided along the stencil conveyance path between the stencil material roll and the printing drum a tension blade which is pressed against the stencil to apply back tension to the stencil when the stencil is run by the printing drum and the tension blade is formed so that the stencil undergoes force which tends to displace outward the stencil from the central portion in the direction of width of the stencil.

Abstract: A two-stroke engine with an isolation chamber. The isolation chamber has a pressure-sensitive wall attached to or slidably mounted within the isolation chamber. The pressure-sensitive wall is substantially impervious to air, oil, and the fuels used in an internal combustion two-stroke engine. When the piston of the engine moves away from the crankcase, a vacuum is created in the crankcase. This draws the pressure-sensitive wall toward the crankcase within the fluid communication circuit, which movement of the pressure sensitive wall also pulls air into the intake side of the isolation chamber through a one-way valve or time induction mechanism. When the piston moves toward the crankcase, the increased pressure within the crankcase forces the pressure-sensitive wall away, fluidwise, from the crankcase and thus pushing air from the isolation chamber into the combustion chamber. The pressure-sensitive wall therefore is effective in preventing oil from flowing into the combustion chamber from the crankcase.

By passing over the exhaust port, the piston ring better accommodates fluctuations in dimensions that are induced by temperature changes by passing over other regions of the cylinder wall, the piston ring enhances the distribution of lubricant, especially in cylinders having a generally horizontal or inclined center axis.
