US Patent:

41649605, Aug 21, 1979

Filed:

Feb 13, 1978

Appl. No.:

5/877335

Inventors:

Charles W. Howard - San Dimas CA

Assignee:

Early California Industries Inc. - Phoenix AZ

International Classification:

F16K 1900

US Classification:

137604

Abstract:

A fluid mixer for mixing a carrier liquid such as water with a thickening agent such as a liquid polymer employs a mixing apparatus in the form of an elbow pipe interconnecting the carrier liquid inlet with a discharge pipe. The polymer thickener is introduced into the fluid stream of the carrier liquid at a point on the outer radius of the elbow where the high velocity stream of carrier liquid impinges upon the side of the elbow pipe to cause the thickener to be impinged upon by the carrier stream at the point of its highest velocity to impart maximum hydraulic shear to the thickener liquid, insuring optimum mixing of the two liquids in the discharge pipe.

Early California Industries, Inc. - Los Angeles CA

International Classification:

G05D 1103

US Classification:

137 88

Abstract:

A fluid-blending system supplies a constant preestablished ratio of two or more fluids through a common output conduit over a wide range of variations of the flow rate established through the output conduit by a pump controlling such flow rate. This constant ratio also is maintained in spite of variations in the different head pressures of the fluids supplied to the blender. Separate fluid supply chambers are used for each of the fluids to be blended and are connected in common to the output conduit. The inlet orifices for each of the fluid supply chambers are normally closed by diaphragm-controlled valves mounted in the chambers. The amount of valve opening is controlled by pressure-sensing diaphragms in response to a partial vacuum created by the demand for fluid in the output conduit. The operation of the diaphragms is such as to maintain the same absolute pressure in each of the fluid supply chambers, so that the blender system is unaffected by variations or differences in the head pressures of fluids supplied to the chambers.

Charles S. Howard - Upland CA

International Classification:

B65D 4320
B65D 8556

US Classification:

206540

Abstract:

A dispensing and storage container for various articles, particularly pills, wherein the stored articles are readily available when needed, without risking the chance of the container being opened accidentally, the container comprising a cover adapted to slidably received a rectangular receptacle formed to define a compartment. The cover includes longitudinal side walls having channels disposed therein to slidably receive rail members integrally formed along the side walls of the receptacle. To prevent accidental opening of the container the forward wall of the receptacle is provided with a lock recess in which a locking lug is removable received, the locking lug being integrally formed along the forward edge of the cover. In order to unlock the cover from the receptacle, the cover is provided with a pair of oppositely arranged, flexible tab members which, when pressed inwardly, cause the cover to bow and thus disengage the locking lug from the locking recess, whereby the cover can be moved rearwardly of the receptacle and thus expose the storage compartment.
