| 20120132838 | MANUAL TO AUTOMATIC VALVE CONVERSION DEVICE - An apparatus and method for automating the operation of a manual control valve upon the occurrence of a specified condition includes a valve handle engaging member mounted on an operating shaft turned by a motor held by a housing or support which is mountable to the manual valve body or associated conduit. The motor is operated by a motor control circuit when a sensor detects the condition. The structure and method of mounting may include a quick disconnect mechanism. The control circuit may operate at different power levels depending on the state of the sensor. | 05-31-2012 |

| 20090316238 | OPTICAL SECURITY DEVICE - A holographic effect generating structure (HEGS), either stand alone or integrated with a security diffractive image, generates a holographic optically varying image by a process of diffraction of light, this image under white light illumination generates a smoothly and continuously variable structureless optically variable apparent motion effect which moves along a pre-determined track within pre-determined limits, the device characterised that it generates 3 planes of images under white light illumination—an image plane image located at or near the image plane corresponding to the real plane of the device which defines the predetermined movement track of the apparent motion effect and its bounds, a second virtual image plane situated away from the image plane of the device forming a virtual viewing zone corresponding at which an observer would be positioned to observe the visual effect and a third image plane, which defines a region where all the light rays from the image plane artwork to the viewing zone pass through or appear to originate from which defines the defines the viewing track of the apparent motion effect. | 12-24-2009 |

| 20090312995 | SYSTEM AND METHOD FOR MODELING FLOW EVENTS RESPONSIBLE FOR THE FORMATION OF A GEOLOGICAL RESERVOIR - A system configured to model geometric architectures of flow events in geological reservoirs. In one embodiment, the system comprises a geological control input, a rules module, and a modeling module. The geological control input is configured to receive a set of environmental conditions that act as geological controls impacting a geometric architecture of a geological reservoir at a point in geologic time. The rules module is configured to apply a set of rules to the set of environmental conditions present at the point in geologic time to determine geometric flow parameters of the geometric architecture, wherein the set of rules comprise one or more empirical rules. The modeling module is configured to model the geometric architecture based on the geometric flow parameters determined for the flow event by the rules module. | 12-17-2009 |

| 20110215610 | Retrofit Tailgate Damper - A tailgate control mechanism used to exert a force on a pivot. The tailgate may include a pivoting main body and a pivot fixed to a truck bed, where the main body may move about the pivot. The tailgate may also include a piston element including a first end connected to the pivot and a second end connected to the main body. The second end may be positioned above the first end when the main body is in a closed position. The piston element may also be configured to provide a counter force to balance the weight of the tailgate. The piston element may also be retrofitted. | 09-08-2011 |
| 20110217662 | IGNITION SYSTEM FOR PORTABLE LPG BURNER - A gas-fired heat gun is ignited using an electrode tip located downstream of a flame holder such that the electrode tip is in the path of the flowing gas. The electrode is connected to a voltage source that causes a spark to jump from the electrode tip to another part of the heat gun, such as the flame holder or a casing of the heat gun, when a trigger is pulled, thereby igniting the flowing gas. The electrode is typically a thin wire extending through a portion of a diffuser defining a portion of the gas flow path upstream of the flame holder. The electrode may be continuous from the diffuser to a terminal end downstream of the flame holder. | 09-08-2011 |
