Title: Subassembly electrical isolation connector for drill rod
Inventor: LOGAN DEREK W
IPC: E21B47/13
Filed: 1999-01-25
Abstract: A subassembly electrical isolation connector for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations electrically isolates the inner connection of the drill rods.      The connector comprises a housing, a mandrel, a connector for connecting the housing to a first tubular drill rod, a connector for connecting a mandrel to a second tubular drill rod and a device for interconnecting the housing and the mandrel in a manner to electrically isolate the housing from the mandrel with the housing overlapping at least a portion of the mandrel. The housing has an isolated end which is electrically isolated from the mandrel and the connector for connecting the mandrel to a second tubular drill rod. Such arrangement provides enhanced strength to resist bending moments along the connector and resisting drilling forces. The subassembly is particularly useful in applications involving directional drilling in earth formations, particularly oil well drilling, the drilling of bore holes under river beds and other obstacles and earth formations, bore hole inspection systems, directional drilling in respect of geothermal wells, ventilation shaft drilling in mineral mining formation and the like.

Title: Roughener for grips and handles
Inventor: LANDYMORE W M
IPC: A63B57/00
Filed: 1999-04-19
Abstract: A device for roughening the worn or smooth grip of a golf club or other handled item includes a flat plate member with an aperture therethrough. A plurality of sharp-tipped serrations extend around the periphery of the aperture, with the tips defining a circular line that has a diameter greater than the maximum diameter of a grip at the free end thereof.  Adjacent serrations define a valley therebetween. In use, the plate member is clamped in a bench vise and the grip, still affixed to its golf club, is moved through the serrated aperture with a radially directed force being applied thereto so that the serrations will cut a series of grooves into the material of the grip. Preferably the grip will be rotated and moved reciprocally through the serrated aperture so that a random pattern of grooves is cut into the grip, thereby restoring the grip to a condition that approximates its original textured surface. The device may include a set of transversely extending saw-tooth-like serrations along one transverse edge thereof for roughening the grips or handles of other handled items, including golf clubs.

Title: Proton beam digital imaging system
Inventor: BLAIR MARK S
IPC: A61N5/10
Filed: 1997-10-27
Abstract: A proton beam digital imaging system comprising an X-ray source which is movable into the treatment beam line that can produce an X-ray beam through a region of the patient. An X-ray receiver receives the X-ray beam after it has passed through the patient and the X-ray receiver generates photons that correspond to the X-ray image. The photons are directed to a TEC CCD camera to produce a patient orientation image which displays the orientation of the center of the beam relative to selected monuments in the patient's skeletal structure. The system also receives a master prescription image which displays the target isocenter with respect to the same selected monuments of the patient's skeletal structure. By comparison of the relative positions of the center of the beam in the patient orientation image and the isocenter in the master prescription image with respect to the selected monuments, the amount and direction of movement of the patient to make the beam center correspond to the target isocenter is determined.

Abstract: An ozone fade resistant dyed carpet made of dyed sheath/core face fibers has a sheath substantially or completely covering the core. The sheath is composed of a fiber-forming polymer which is inherently chemically compatible and is selected from polymers that are resistant to dye migration and yet inherently chemically compatible with the core polymer. The face fibers are dyed with at least one acid dye, basic dye or disperse dye and resist ozone fading as indicated by a CIEL*a*b* total color difference from the original unexposed sample after at least 3 cycles of ozone fading that is less than one-half of the CIEL*a*b* total color difference seen for a fiber composed substantially completely of said core polyamide component that is dyed with the same dyes. The fibers may be cabled and heatset in which case even more substantial improvement in the ozone fastness is observed.

Patent CA-2282117-A1 (CA)
Title: Optical switching gate
Inventor: MACDONALD ROBERT I
IPC: G02F3/00
Filed: 1999-09-13
Abstract: The present invention relates to an optical logical AND gate comprising an erbium doped waveguide which is attenuating at a signal wavelength and responsive to pump light energy to be transmissive at a signal wavelength. A first laser pump excites a portion of the waveguide. A second laser pump excites a remaining portion of the waveguide. The waveguide is only transparent to transmit a signal if both the first and second pumps excite the waveguide together. The optical AND gate of the present invention can be used as the control element of an NxN matrix. A number of first ports and a number of second ports are interconnected by erbium waveguide AND gates. Pump light is switched to a selected first port. Pump light from a second pump is switched to a selected second port. Only the erbium waveguide gate interconnecting the selected first and second port is transmissive to switch a signal. All other gates are attenuating and other signals are accordingly blocked. A single signal can be switched to a selected output or to a number of outputs to achieve a broadcast function. Advantageously, active switch elements are removed from the signal path, and the signal is switched passively. This switch unit is used to advantage in a multiple stage switch architecture.

Patent CA-2285972-A1 (CA)
Inventor: MOSTAFA MOHAMED
IPC: H04L12/46
Filed: 1998-04-14
Abstract: A communication protocol proxy enables a CEBus network to be mapped across a non-CEBus network, thereby allowing a remotely located node (e.g., a controller) to communicate via a non-CEBus network with electronic devices connected to the CEBus network, while still conforming with the EIA/IS-60 protocol requirements. In a preferred embodiment, a proxy node is provided on a CEBus network, wherein the proxy node is also connected to a non-CEBus network, (e.g., a wide area network ("WAN")), such that a remotely located controller on the non-CEBus network may communicate with a device on the CEBus network by transmitting messages to the proxy node over the non-CEBus network.  The proxy node then forwards the message to the respective CEBus device over the CEBus network. If the message requires a CEBus Ack message response, the CEBus device transmits a CEBus Ack message to the proxy node, so that it is received within the time interval specified by the CEBus standard. On receiving the CEBus Ack message, the proxy node transmits a non-CEBus standard acknowledge message to the controller, which can be received over an extended time interval. If the message does not require a CEBus Ack message response, the proxy node still transmits a non-CEBus standard acknowledge message to the controller in order to verify receipt of the message.

Abstract: The present invention is intended to obtain an ethylene copolymer composition having excellent transparency, mechanical strength and moldability. The ethylene copolymer composition comprises an ethylene/ .alpha.-olefin copolymer and high-pressure radical process low-density polyethylene. The ethylene/.alpha.-olefin copolymer is a copolymer of ethylene and an .alpha.-olefin of 6 to 8 carbon atoms and has the following properties: the melt tension (MT) and the melt flow rate (MFR) satisfy the relation 9.0×MFR-0.55 > MT > 2.2×MFR-0.84; the activation energy ((E a)×10 -4 J/molK) of flow, the carbon atom number (C) of the .alpha.-olefin in the copolymer and the .alpha.-olefin content (x mol%) in the copolymer satisfy the relation (0.039Ln(C-2)+0.0096) × x+2.87 < E a×10 -4 <=  (0.039Ln(C-2)+0.1660) × x+2.87; and the haze of an inflation film produced from said copolymer satisfies a specific relation. This ethylene copolymer composition can be used for producing molded products such as films, sheets, packaging materials, injection molded products, expansion molded products and fibers. These molded products are excellent in mechanical strength, heat resistance or transparency.
