Abstract: A flush handle assembly itself and a stationary frame 36 can be prevented from being damaged even when a door 35 is opened and closed in a condition in which a front end of a latch 30 is projected from the door 35. In the assembly: a handle 9 has its base end pivoted to side walls 3 of a casing 1 through a pivot 18; a leaf spring 19 keeps the handle 9 in position and urges the same to be projected from or retracted in the casing 1; the latch 30 is received in a latch casing 24 and is urged by a spring 33 to move forward; a control projection 17 of a rear surface of the handle 19 is abutted on an oblique-plate portion 32 of a side surface of the latch element 30; the projection 17 of the handle 19 is moved back and forth as the handle 19 is projected or retracted, so that the latch 30 is slidably moved horizontally along guide portions 28, 29 of the latch casing 24.

Abstract: Waste-gas suppressor for internal-combustion engines, utilizing negative pressure generated in the carburetor of the engine. A flow-regulator valve operated by the negative pressure adjusts water flow in proportion to engine speed, the water being evaporated by the exhaust heat of the engine. The resulting steam is supplied to the combustion chamber of the engine.

The resulting steam is supplied to an air cleaner, and the cleaned air containing the steam is supplied to the combustion chamber of the engine.
