Patent CA-2452100-A1 (CA)
Title: Centering device
Inventor: JENNER ANDREW
IPC: E21B17/10
Filed: 2002-06-20
Abstract: A spring centraliser device for supporting a tubular member spaced from the wall of a bore is made from a single piece of boron steel material. The spring centraliser device has first and second collars spaced apart along a longitudinal axis. Spring bow portions extend between the collars. As the device is made from a single piece of material, the material extends seamlessly from each collar portion through the bow portions so that there are no joins or points of weakness. Use of boron steel means that the device can be made by cold forming.

Title: Weighted gradient method and system for diagnosing disease
Inventor: GRAOVAC MILAN
IPC: A61B6/00
Filed: 2004-03-23
Abstract: A method for detecting and diagnosing disease states in a body part is described. The method starts with a preparatory step of modeling the body part as a grid of many finite elements, then calculating the effect of the electrical property of each finite element at any one of a plurality of electrodes on the periphery of the body part as a function of the position of the finite element within the grid. This is termed the weight (influence) of the element.    With this baseline information, electrical impedance measurements made at the plurality of electrodes on the periphery of the body part can be used in a diagnostic module to calculate a Weighted Element Value (WEVaI) for each element. In a preferred embodiment of invention, the difference in WEVaI magnitude between corresponding elements of homologous body parts serves as an indicator of the presence of disease.

The hopper conveys material in the direction of movement of the unit and the material is dispensed from the conveyor into the trench to form the bed. An adjustable height blade is provided which both sets the bed height and also smoothes the bed upper surface. As the unit moves, the utility or utilities are laid on the bed upper surface. Thereafter, material is dispensed from the bottom of the hopper on top of and around the utility or utilities to encase them. An adjustable height blade is also provided to set the height of the encasement and also to smooth out its upper surface.

Title: Method for operation of a power generation plant
Inventor: KOLLER MARTIN
IPC: H02J3/28
Filed: 2003-06-30
Abstract: The invention relates to a storage power station (S), for example an air storage plant, comprising a compressor unit (V), a turbine unit (T), and a storage volume (100). Said storage power station is operated according to a special mode of operation which enables it to react as quickly as possible t o changes in the load requirements. According to the invention, rapid changes in the load requirements are compensated by regulating the power absorption of the compressor unit (V), resulting in a variable net power output at the sam e time as a constant power output of the turbine unit (T). The power of the compressor unit can be regulated faster than a regulation of the power engin e, by approximately one order of magnitude. In extreme cases, the compressor un it can be simply switched off, whereby within seconds the drive power thereof i s released for an electricity network. The turbine unit can meanwhile continue to be normally operated and slowly follow the power requirement, reducing th e load on the turbine. A storage power station operated according to the invention is outstandingly suitable for frequency support and for covering rapid load ramps in an electricity network.
