Abstract: A method of preventing separation of a vertically adjustable support column having sections connected together by mating threads and a support column. External threads of a second section are mated with internal threads of a first section until a first end of the second section protrudes into an enlarged diameter portion of an interior bore of the first section immediately adjacent to the internal threads. A top few of the external threads at the first end of the second section are mechanically damaged. The mechanically damaged threads prevent the first end of the second section from being removed from the enlarged diameter portion of the first section but permit relative telescopic adjustment of the first section and the second telescopic section within a limit provided by the enlarged diameter section.

Patent CA-2251627-C (CA)
Inventor: HSU MICHAEL S
IPC: H01M8/24

Granted: 2002-07-30
Abstract: A natural gas reformer (10) comprising a stack of thermally conducting plates (12) interspersed with catalyst plates (14) and provided with internal or external manifolds for reactants. The catalyst plate is in intimate thermal contact with the conducting plates so that its temperature closely tracks the temperature of the thermally conducting plate, which can be designed to attain a near isothermal state in-plane to the plate. One or more catalysts may be used, distributed along the flow direction, in-plane to the thermally conducting plate, in a variety of optional embodiments. The reformer may be operated as a steam reformer or as a partial oxidation reformer. When operated as a steam reformer, thermal energy for the (endothermic) steam reforming reaction is provided externally by radiation and/or conduction to the thermally conducting plates. This produces carbon monoxide, hydrogen, steam and carbon dioxide. When operated as a partial oxidation reformer, a fraction of the natural gas is oxidized assisted by the presence of a combustion catalyst and reforming catalyst. This produces carbon monoxide, hydrogen, steam and carbon dioxide. Because of the intimate thermal contact between the catalyst plate and the conducting plates, no excessive temperature can develop within the stack assembly. Details of the plate design may be varied to accommodate a variety of manifolding embodiments providing one or more inlets and exit ports for introducing, pre-heating and exhaust the reactants.
Patent CA-2252246-C (CA)

Granted: 2004-10-12
Abstract: A system is disclosed for generating and transmitting data signals to the surface of the earth while drilling a borehole, the system operating by generating pressure pulses in the drilling fluid filling the drill string. The system is designed to maximize signal strength while minimizing the probability of jamming by drilling fluid particulates. The system uses a rotary valve modulator consisting of a stator with flow orifices through which drilling fluid flows, and a rotor which rotates with respect to the stator thereby opening and restricting flow through the orifices and thereby generating pressure pulses. The flow orifices with the stator in a "closed" position are configured to reduce jamming, and to simultaneously minimize flow area in order to maximize signal strength. This is accomplished by imparting a shear to the fluid flow through the modulator, and minimizing the aspect ratio and maximizing the minimum principal dimension of the closed flow area. A preferred embodiment and three alternate embodiments of the modulator are disclosed.

Abstract: A device, used in particular in telecommunications technology to supply power to parallel-connected, electrical loads has side-by-side arranged potential lines. These are secured inside a connecting housing, with connections for supplying the operating potential. The connections supply plug-in modules for connecting individual loads, which modules are fitted against the connecting housing in longitudinal direction of the potential lines. The potential lines are configured as rigid, parallel bus bars that project on a side from the connecting housing. With the aid of passages that make contact with the bus bars, the plug-in modules are fitted side-by-side onto the bus bars, such that they fit against the connecting housing or against each other, and are frictionally secured.

Granted: 2008-07-08
Abstract: A remote traffic data exchange and intelligent vehicle highway system is provided. In-vehicle equipped devices locate time-related vehicle positions on a digitized road network using information received from a global position system and send the time-related vehicle positions to a traffic service center. The traffic service center collects the road traffic data from all vehicles that travel in the roadway system and installed with the devices, processes the data and provide a real-time traffic forecast and digitised road network. The in-vehicle equipped devices receive the real-time traffic forecast and the digitised road network, and provide route guidance services based on the traffic forecast for the drivers. The traffic forecast is based on normal traffic conditions in a historic period and adjusted by factors related to real-time abnormal traffic situations. The system provides a practical and economic solution for building such an intelligent vehicle highway system in a wide area and providing a general and complete traffic forecast for the public.

Abstract: A plate yoke has an upper surface formed with a projection and a guiding rail. A new magnet block is transported by sliding on the upper surface of the plate yoke, and is bonded side by side with the projection or a magnet block which is already fixed. During the above operation, a magnetic member is held above the plate yoke. Preferably, the new magnet block is transported toward a corner portion, with side surfaces of the magnet block held parallel to a side surface of the projection and a side surface of the guiding rail respectively. When the magnet unit and the column yoke is connected, the column yoke or the magnet unit is lowered so that a guiding rod attached to an end face of the column yoke is inserted into a hole formed in the magnetic unit. Further, the column yoke is guided by a guiding member disposed between a permanent magnet on the plate yoke and a position where the column yoke is to be connected on the plate yoke.

Title: Method and apparatus for stretch wrapping a load
Inventor: LANCASTER PATRICK R III
IPC: B65B11/04
Filed: 1999-08-10
Granted: 2005-03-22
Abstract: A leading end of packaging material is grasped in a packaging material holder while a load is wrapped. Packaging material is dispensed from a packaging material dispenser, and relative rotation is provided between the dispenser and a load to wrap packaging material around the load. The packaging material holder may be positioned on the rotating surface of a turntable but isolated from any electrical or fluid power source of a rotatable surface of the turntable. During the wrapping cycle, the packaging material holder moves downstream along the turntable, automatically releasing the leading end of the packaging material and automatically grasping a trailing end of the packaging material. The packaging material is weakened and then severed between the packaging material holder and the load. The packaging material holder is mounted to permit it to move upstream due to force exerted by the packaging material held in the holder.

Abstract: An enhanced mechanisim (400) for the reverse link power control in a wireless communication system, especially for high speed data applications and fixed wireless communication applications, dynamically adjusts the power control step size (404, 408, 412) of the reverse link power control. The power control step size is dynamically adjusted based on various factors including types of service, number of reverse supplemental code channels, total received power at the base station, estimated diversity gain and required mobility, among others. The system which includes stationary infrastructure, can query a subscriber unit's capability in the support of a pre-defined set of power control step sizes before assigning it to the subscriber unit (402, 406, 410). Furthermore, the subscriber unit may decide its optimized power control step size based on certain feedbacks from the system. In a specific embodiment, enhancement to the ANSI EIA/TIA-95 system is provided such that it supports a variable subscriber unit power control step size and associated signaling in accord with this invention.
