Title: Earth-boring tools having expandable members and related methods
Inventor: RADFORD STEVEN R
IPC: E21B10/32
Filed: 2010-09-30
Abstract: Expandable apparatus for use in subterranean boreholes include a tubular body having at least one opening and at least one member positioned within the at least one opening. The member is configured to move between a retracted position and an extended position. A sleeve member including a constricted portion may be disposed in the tubular body and may selectively retain the at least one member in the retracted position. In some embodiments, the sleeve member may be biased in an initial position. Methods of moving a member of an expandable apparatus include repeating retracting and expanding of the member.

Title: Inclusion detection in polished gemstones
Inventor: SMITH JAMES GORDON CHARTERS
IPC: G01N21/87
Filed: 2010-11-02
Abstract: A method and apparatus for generating a 3D model of and/or detecting inclusions in a polished gemstone such as diamond is described. The gemstone (103) is rotated in a series of discrete increments. At each rotational position of the gemstone, the gemstone (103) is illuminated with collimated light (111,112) and a silhouette image recorded. At each rotational position, the gemstone (103) is also (before further rotation) illuminated with diffuse light (109), and a diffuse image recorded. The images are analysed to obtain a 3D model of the surface of the gemstone. Features may then be identified in the diffuse images and tracked between subsequent diffuse images. The tracked features may be located relative to the 3D model of the gemstone, taking into account reflection and refraction of light rays by the gemstone. Some or all of the located features may then be identified as inclusions.

Abstract: An apparatus for facilitating sequential viewing of streams of images of a common scene. The images are captured by an image sensor system having different viewing configurations generating visually dissimilar views. The electronic circuitry is configured, on transition between a first and a second viewing configurations, to input images captured using the first or second viewing configurations, and to generate a signal, derived from the input images. The signal corresponds to a gradual graphic transition between images captured using the first and the second viewing configurations, thus simulating a continuous viewing of the common scene. The gradual graphic transition includes transition due to a change of viewing direction, a change of aspect ratio, a change of sensor technology, a change of spectral sensitivity, a change of sensor sensitivity, a change of spatial resolution a change of sensor location, a change of binning level a change of displayed region of interest.

Abstract: A system for discharging hydrogen from two or more hydrogen storage vessels (1A, 1B, 1C) containing solid hydrogen storage material. The system includes at least one hydrogen supply line for connecting the hydrogen storage vessels to a hydrogen demand (3), an energy delivery system (6A, 6B, 6C) to provide heat to the hydrogen storage material in each hydrogen storage vessel to desorb hydrogen from the solid hydrogen storage material, and one or more supply connection conduits (4A, 4B, 4C) for connecting the supply line or lines to the hydrogen storage vessels (1A, 1B, 1C). Each supply connection conduit has a backflow prevention device (5A, 5B, 5C) to prevent hydrogen in the supply line from flowing back into the hydrogen storage vessels (1A, 1B, 1C). Also disclosed is a system for delivering a supply of hydrogen to a hydrogen supply line including a control system (7) to determine the timing of activation of an energy delivery system based (6A, 6B, 6C) on the hydrogen demand in the hydrogen supply line. The control system (7) activates the energy delivery system (6A, 6B, 6C) in the next hydrogen storage unit to provide a sufficient period of time for the material in the next hydrogen storage vessel to heat to the temperature at which hydrogen is provided at the supply pressure for the hydrogen supply line.

Inventor: GRIMES DAVID J
IPC: F04B17/00
Filed: 2011-06-02
Abstract: An exemplary magnetically-driven fluid pump includes a magnet housing ("cup") that enables one or more sensors to be in indirect ("non- wetted") contact with the pumped fluid while avoiding the static seals normally required with sensors that are mounted to a fluid conduit or chamber and extend into the fluid pathway. Sensors may be used for monitoring the fluid or for feedback control of the pump. By coupling sensors directly to electronic circuits that control the pump, the number of wires located outside the motor housing is minimized, making the assembly more rugged. This is particularly advantageous in hazardous environments or submerged applications. Pumps and hydraulic systems disclosed exhibit fewer leaks under more aggressive pumping conditions and while providing improved pump performance, compared to conventional pumps and systems.

Filed: 2011-06-16
Abstract: A catalytic tank heater includes a catalytic heating element supported on an LPG tank by a support structure that holds the element in a position facing the tank. Vapor from the tank is provided as fuel to the heating element, and is regulated to increase heat output as tank pressure drops. The heating element is internally separated into a pilot heater and a main heater, with respective separate fuel inlets. The pilot heater remains in continual operation, but the main heater is operated only while tank pressure is below a threshold. Operation of the pilot heater keeps a portion of the catalyst hot, so that, when tank pressure drops below the threshold, and fuel is supplied to the main heater, catalytic combustion quickly expands from the area surrounding the pilot heater to the remainder of the catalyst.

Abstract: The invention is directed to an accessory which is fabricated and shaped to cover the bosom area of body. It is particularly useful when applied to a brassiere showing a cleavage of a human body at a center thereof. The accessory, when applied to a brassiere will cover the cleavage area of a wearer to simulate an undergarment. The inventive accessory can be removed from the brassiere when the person is in a different social setting. The accessory can be fabricated from different materials but it is preferred to be stretchable so that it can be applied to differently sized brassieres and the accessory, additionally, can move with the movements of the wearer. It is preferred that the fabric of the accessory be doubled over so that most of the fastening elements do not touch the skin of the wearer which adds to the comfort of wearing the accessory.
