Title: Geothermal pipe setting tool
Inventor: PULLMAN DOUGLAS G
IPC: F24J3/08
Filed: 2011-05-19
Abstract: A pipe setting tool includes a tool shaft, a coupler mounted on a first end of the tool shaft, and a tool sleeve affixed to the tool shaft defining a space therebetween. An outside diameter of the tool sleeve ensures close conformity to a borehole to position a geothermal pipe mounted thereto in close proximity to the outside diameter of the borehole. A moveable seal cap may be mounted on the tool shaft, moveable between a first position spaced-apart from the tool sleeve during down-hole movement of the tool to permit fluid flow through the space and a second position against the tool sleeve during up-hole movement of the tool to establish a seal with the tool sleeve to prevent fluid flow through the space. A second end of the tool shaft may receive a pipe hook to attach a geothermal pipe to the pipe setting tool.

Title: Gas-fired portable radiant heater
Inventor: VANDRAK BRIAN S
IPC: F24H3/06
Filed: 2004-09-30
Abstract: A portable heater (A) adapted for use in a recreational enclosure or temporary work enclosure includes a housing (10) having an air inlet (40) on the lower front face. A  gas supply (50) is at least partially enclosed by the housing which provides propane to the mouth (64) of a burner venturi (60) located within the housing. Air is drawn through the air inlet and also enters the mouth of the burner venturi. The air and gas are mixed thoroughly as they travel upwardly through the burner venturi. A chimney effect increases fresh air flow velocity into the burner venturi and allows the heater to operate at a reduced fuel gas pressure. Upon exiting the burner venturi, the air/gas mixture is to a plenum (72) and radiant surface (70) where combustion takes place.
Patent CA-2761072-A1 (CA)
Title: Subsea overload release system and method
Inventor: MOHR HARVEY O
IPC: E21B33/08
Filed: 2010-04-30
Abstract: The disclosure provides a subsea overload release system and method. The disclosure provides a releasable connection system that can be overridden during an overload condition, and is resettable in a subsea location in situ. During normal operation, a collet sleeve is slidably engageable with a collet having one or more fingers that can releasably couple a first member with a second member. During an overload condition, an overload piston acting on fluid in an overload reservoir causes an overload pressure and a rupture or other release of fluid through an overload pressure member, causing the overload reservoir to at least partially collapse. The collapse allows the system to extend and force open the fingers to disengage the second member from the first member. When the overload symptom is rectified, the overload reservoir can be reset and the overload pressure member reset or replaced without requiring repairs above sea surface.

Title: Controllable prosthetic joint system
Inventor: HERR HUGH M
IPC: A61F2/38
Filed: 2001-03-29
Abstract: The invention relates to an automated speed-adaptive and patient-adaptive control scheme and system for a knee prosthesis (110). The control scheme and system utilizes sensory information measured local to the prosthesis (110) to automatically adjust stance and swing phase knee resistances to a particular wearer under a wide variety of locomotory activities. Advantageously, no patient-specific information needs to be pre-programmed into the prosthetic knee (110) by a prosthetist or the patient. The system (110) is able to adapt to various types of disturbances once the patient leaves the prosthetist's facility because it is patient-adaptive and speed-adaptive.

Title: Non-binary holograms for increased capacity
Inventor: HERSHEY JOHN ERIK
IPC: G11B7/0037
Filed: 2011-12-15
Abstract: Techniques are provided for increasing storage capacity in a holographic storage system.  While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded in each data position. In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.
