142	Multiple liquid proportional dispensing device	US530770	1983-09-07	US4585150A	1986-04-29	Robert C. Beacham; Robert E. Switek, Jr.; Jack Buelow
The apparatus of this invention is for dispensing two liquids so that the ratio K of the flow rates of the liquids is substantially constant. The apparatus comprises two containers each having a dispensing orifice and an air vent passage having two ends, an inlet end at the outside surface of the container and an outlet end inside the container. In the preferred embodiment, the containers are geometrically proportional in shape with the dispensing or pouring orifices and vent passages all in corresponding locations. The ratio of the cross-sectional areas of the pouring orifices of the two containers is C K.sup.5/6 where C is the ratio of the flow coefficients of the two liquids to be poured. When the containers are placed in the same spatial orientation and each filled to the same proportion of fullness with different liquids and then tilted simultaneously to the same pour angle while maintaining the outlet end of the vent passage at a higher elevation than the pouring orifice for each container, the ratio of the flow rates of the liquids poured from the pouring orifices of the containers is equal to K.

145	MASONRY BLOCK HAVING A BIASED-RUBBER FACE	US16194541	2018-11-19	US20190249429A1	2019-08-15	Nasser M. AL-AQEELI; Homoud M. ASSEHDI; Mohammad MASLEHUDDIN
A cementitious composite and cured masonry block made from the cementitious composite. The cementitious composite contains a cement, a non-rubber aggregate, a crumb rubber and at least one of cement kiln dust and limestone powder. The crumb rubber aggregate is extracted from scrap tires after being processed and then mixed in specified percentages with the aggregate, the cement and water, then cured in forms to make the masonry blocks. In the present disclosure sand, which is used in conventional masonry blocks, is at least partially replaced with crumb rubber to produce a sand-free or sand-reduced masonry block that contains crumb rubber. The crumb rubber masonry blocks satisfy the ASTM non-load bearing requirements. The use of crumb rubber decreases the unit weight and increases thermal resistance of the masonry blocks. The use of cement kiln dust or limestone as a partial replacement of cement will lead to decrease in the cost. The use of industrial waste materials, such as crumb rubber, limestone powder and cement kiln dust, will lead to economic and environmental benefits.
