Title: Electronically enabled forms
Inventor: WITHUM TIMOTHY O
IPC: G06F19/00
Filed: 2007-04-05
Abstract: Electronically readable forms include radio-frequency identification (RFID) devices enabling automated processing of the forms to obtain indicated responses to questions as well as entered information. In one embodiment, an electronically readable form (10) includes a substrate (12), a plurality of response areas (14A-14G) thereon, and a plurality of separate radio frequency identification (RFID) devices (20A-20G) thereon that are associated with the response areas (14A-14G). The response areas (14A-14G) may correspond with answers (16A-16G) to questions (18A-18C). Upon appropriate indication of a response within its associated response area (14A-14G), each RFID device (20A-20G) is enabled to transmit a code (22) in response to an activation signal (30) from an RFID reader unit (32). Each code (22) is different permitting a determination of which response areas (14A-14G) have responses indicated therein based on the codes (22) that are received by the RFID reader unit (32).
Patent CA-2584988-A1 (CA)
Inventor: ETO KOICHI
IPC: F16F15/26
Filed: 2005-11-08
Abstract: A device for removing engine vibration, capable of effectively removing secondary vibration cause by reciprocation of a piston (21) of a multilink-type variable compression ratio engine (E). The secondary vibration can be removed even if the direction of the secondary vibration is inclined relative to the cylinder axis (L1), and the removal is made by inclining the direction (see the arrow direction) of vibration exciting force, produced by a secondary balancer device (43), so that it matches the direction of the secondary vibration. The secondary balancer device (43) is constructed by having balancer weights (44a, 45a) respectively supported by a pair of balancer shafts (44, 45) rotating in the directions opposite from each other.  Displacing the phases of the balancer weights (44a, 45b) enables the direction of the produced vibration exciting force to be inclined so that it matches the direction of the secondary vibration of the engine (E).

Inventor: HAGGERTY PETER DALE
IPC: B01D61/00
Filed: 2005-10-25
Abstract: Forward osmosis methods and apparatus using a controllable osmotic agent to establish or enhance an osmotic forward bias are disclosed. In a conventional osmosis environment, a controllable osmotic agent is selectively added to an effluent to establish or enhance an osmotic imbalance that favors transfer of an influent solvent to the effluent. After desirable transfer of the influent solvent to the effluent, the controllable osmotic agent is isolated e.g. by magnetic forces, removed or neutralized so that the transferred solvent and/or concentrated influent can be recovered. The controllable osmotic agent comprises a composition that is reactive to an external influence that does not appreciably affect the effluent solvent, for example, magnetic forces, electrical charges and filtration. Batch and continuous process methods and apparatus are also disclosed.

Title: Fiber optic cable with integral radio frequency identification system
Inventor: COOK THOMAS C
IPC: H02G1/00
Filed: 2007-05-18
Abstract: A communication cable, such as an optical fiber cable, can comprise radio frequency identification ("RFID") elements that facilitate locating and identifying the cable. The RFID elements can provide information about the cable from a remote location, for example when the cable is spooled in a warehouse, buried underground, suspended overhead, or installed in a cable tray. The RFID elements can be attached at defined locations along a plastic tape within the cable. Each RFID element can comprise an antenna that extends lengthwise along the tape and/or circuit traces or other components that are imprinted on the tape. Each RFID element can have a unique code or address, thereby providing a record of manufacturing parameters that are specific to that cable. Also, the unique code can be specific to an incremental length of cable.  Accordingly, the RFID elements can yield information about each fiber segment of the cable.

Abstract: A stinger for attachment to the lower end of a cylindrical shroud for a submersible pump of an artificial lift assembly comprises an elongate tubular member having screened openings to permit passage of well fluids into the stinger and thence to the pump while preventing the entry of larger debris particles. The stinger is substantially smaller in diameter than the shroud, so as to create an annular debris chamber between the stinger and the inner wall of the wellbore or casing into which the stinger is to be inserted. The stinger may a guide member to facilitate manoeuvring the lift assembly past or into lateral wells branching off from a main wellbore. The guide member may have an offset lower end to facilitate entry, or avoidance of entry, into a lateral well. Alternatively, the lower end of the guide member may have a large bullnose section to facilitate passage of the lift assembly past lateral well openings.

Abstract: Self -purging, low force opening, aerosol valve system with an orificed valve stem groove and gasket forming a first valve for product and propellant, or propellant, flow. A check valve element, biasing element and housing first opening form a second valve for product flow. Actuating the valve stem sequentially opens first valve and then second valve. After actuation, second valve closes before first valve, and propellant from housing second opening purges valve stem and actuator until first valve closes. No first valve closing return spring acts directly on valve stem, allowing easy opening.  Gasket in stem groove and product and propellant flow fully close first valve after second valve closes. High solid and/or resin content products can be dispensed through an actuator with mechanical break-up insert.

Abstract: The present invention utilizes simple dimethylsilicone fluids of the proper viscosity/molecular weight added to modify the low temperature properties of polycyclic hydrocarbons. One preferred embodiment of a polycyclic hydrocarbo n is a perhydro dimer of alpha- methyl styrene. Addition of the dimethylsilico ne fluid to the perhydo dimer of alpha-methyl styrene improves the low temperature performance without degrading the requisite low shear stress she ar strength properties. Low viscosity dimethylsilicone lubricating fluids combined with polycyclic hydrocarbons are suitable for use in infinitely variable transmissions providing good Io w temperature flow properties and high shear strength at high temperature and low contact stress conditions.</ SDOAB>

Abstract: Identity document processing equipment with a mechanism designed to maintain tension in a ribbon used in a processing operation in the processing equipment. The tension maintaining mechanism is separate from the supply roll and the take-up roll for the ribbon, eliminating the need for clutches or brakes attached to the supply or take- up rolls to achieve tensioning. Since the tension maintaining mechanism is separate from the supply roll and the take-up roll, the inertia of the supply roll or the take-up roll does not affect the tension on the ribbon during use of the processing equipment.
