Patent number: 6536633Abstract: An apparatus for applying spray texture to a wall, ceiling or the like. The apparatus comprises an aerosol can containing pressurized spray texture material. The spray texture material is released from the can by a valve and passes along a fluid path, out of an outlet orifice, and on to a surface to be textured. The apparatus further comprises an outlet means capable of varying the effective cross-sectional area the outlet orifice.Type: GrantFiled: November 21, 2001Date of Patent: March 25, 2003Assignee: Homax Products, Inc.Inventors: Donald J. Stern, James A. Tryon

Patent number: 6536634Abstract: A fluid dispensing solenoid valve includes a plunger tube that forms an inlet orifice and an outlet orifice. A plunger that forms a fluid chamber is slidably disposed within the plunger tube. The plunger is movable between a fluid fill configuration, wherein the fluid chamber communicates with the inlet orifice to allow the fluid chamber to be filled and a fluid dump configuration, wherein the fluid chamber communicates with the outlet orifice to allow the fluid chamber to be emptied. The fluid dispensing solenoid valve is used to dispense a very accurate quantity of fluid in very controllable manner.Type: GrantFiled: April 5, 2001Date of Patent: March 25, 2003Assignee: Delphi Technologies, Inc.Inventors: Axel H Berndorfer, Ivan Rafael Samalot

Patent number: 6536636Abstract: A support hose applicator and method for applying and removing elastic tubular material from a limb of a patient comprises a resiliently expandable support ring having rotatable sidewalls, and a mandrel with elongated sidewalls on which the support ring fits. The hose or tubular material is applied to a patient by first pulling an open end of the hose over the mandrel. The support ring is then placed over the hose and mandrel. The hose is then rolled onto the support ring as the support ring is rolled along the mandrel. The hose is applied to a patient by rolling the support ring along the limb of the patient while holding a free end of the hose in place. The support ring comprises a plurality of ring segments rotatably mounted on a resiliently expandable band that is expandable to make the ring larger.Type: GrantFiled: November 26, 2001Date of Patent: March 25, 2003Inventor: Thomas B. McDonniel
