Adam Sampson - Ramona CA, US

International Classification:

E03D 1/14

US Classification:

4325

Abstract:

A toilet flush valve that has a moveable buoyant float therein, wherein the float has an open bottom end to trap air therein and wherein the housing includes controls to selectively release air to allow the float to move upwardly therein to permit flushing. By timing when one or two air vents on the housing are open, the duration and volume of the flush can be controlled, with the buoyancy provided by the water lifting the float to open the flush valve. This provides a flushing system with minimal activation energy.

International Classification:

B01D 2126

US Classification:

2190781

Abstract:

A filtration device, apparatus, and method of filtration useful for filtering liquid samples are disclosed wherein filtration occurs opposite the direction of centrifugal force. The filtration device is placed within a container that contains the liquid sample to be filtered. Together, the filtration device and the container comprise the filtration apparatus. Centrifugation forces the liquid sample present in the container to enter the filtration device, thereby effecting filtration. The vertical position of the filtration device is fixed within this container during filtration.

International Classification:

E03D 11/16

Abstract:

A toilet seal for sealing between a plumbing fixture discharge and a waste drainpipe outlet is described. The toilet seal comprises a flange member having an inwardly extending flexible lip. A flexible sleeve extends downwardly from the flange member. The toilet seal further includes a compressible member having an upper surface disposed adjacent to a lower surface of the flange member. The compressible member further has a lower surface and a plurality of ridges extend downwardly from the lower surface of the compressible member.

International Classification:

F16K 31/126
F15D 1/02
F16K 47/06

Abstract:

Some embodiments include a flow regulator with a main body dimensioned to be received within a flow passageway that includes an inlet and an outer surface, and an inner volume positioned within the main body and extending from the inlet along at least a partial length of the main body. Some embodiments includes two separate spiral structures positioned spiraled around the main body where one spiral extends further from the outer surface than the other. Some embodiments include a fluid flow space extending between the spirals. Based on a fluid pressure, the spirals can expand and contract to control the fluid flow space and affect downstream, fluid flow rate as a function of upstream fluid pressure.

International Classification:

E03D 11/16

Abstract:

A toilet seal for sealing between a plumbing fixture discharge and a waste drainpipe outlet is described. The toilet seal comprises a flange member having an inwardly extending flexible lip and one or more raised ridges defining an annular seal extending upwardly from an upper surface of the flange member. The toilet seal further includes a radiused wall extending downwardly from the flange member, which cooperates with the flange member to define a cavity for receiving a compressible member. The toilet seal further comprises a flexible sleeve extending downwardly from the radiused wall. Related methods are described.

International Classification:

E03D 5/10
G01S 15/04
G01J 1/42

Abstract:

A touchless activation system comprising an infrared detector configured to detect an object within a target range, wherein an initial reading is measured by the infrared detector. A second sensor operatively connected to the infrared detector, wherein the second sensor is turned on when the initial reading is measured. The infrared detector measures whether the object is within the target range by comparing the initial reading with an object initiated reflection and determining if a predetermined threshold is exceeded, wherein the second sensor is configured to receive a system activation request. An activator mechanism configured to process the system request and cause the touchless activation system to execute an action associated with the system request. The system is configured to flush a toilet or other plumbing fixture, wherein the system request causes the activator mechanism to flush a toilet.

International Classification:

E03D 5/10
E03C 1/05

Abstract:

A toilet sensor and actuator assembly, having: (a) an infrared sensor configured to detect the presence of an object at a far distance from a toilet; (b) an ultrasonic sensor configured to detect the presence of the object at a near distance from the toilet, wherein the ultrasonic sensor remains in a sleep mode until awakened by a signal from the infrared sensor that the infrared sensor has detected the presence of the object at the far distance; and (c) an actuator mechanism that flushes the toilet in response to a signal from the ultrasonic sensor that the ultrasonic sensor has detected the presence of the object at the near distance.
